- Published on Sep 15, 2009 veröffentlicht
- How the automobile differential allows a vehicle to turn a corner while keeping the wheels from skidding.
Differential steering From Wikipedia, the free encyclopedia
en.wikipedia.org/wiki/Differe...
Differential steering is the means of steering a land vehicle by applying more or less drive torque to one side of the vehicle than the other. Differential steering is the primary means of steering tracked vehicles, such as tanks and bulldozers, is also used in certain wheeled vehicles commonly known as skid-steer, and even implemented in some automobiles, where it is called torque vectoring, to augment steering by changing wheel direction relative to the vehicle. Differential steering is distinct from torque steer, which is usually considered a negative side effect of drive-train design choices.

Let's take a moment to appreciate the machinist who built like 10 progressively complicated miniature differentials for this film.
@Captain Quirk รถ4พั
@Cross8ow pretty sure any science knowledge is build upon a basic foundation.
@KafkaesK I am talking about physics in elementary/high school in Europe, they do not show continuous problem solving to understand. Some teachers might do, but in general no.
@Cross8ow sure they do. U see machines and engines, etc. They do demostrations and let u do practicals. If you're not talking about engineering, then my answer would be not everything in physics can be demostrated physically. Wanna intentionally make a neutron star explodes to demostrate some principles to students?
@KafkaesK yeah but not in a practical and interesting way like this, facing problem each time they "upgraded the system"
"The differential looks complicated, but once we understand its principle, it's amazingly simple". I love that line.
I think we can apply this to humans as well! Mark looks very complicated, but once we understand his principal, he’s amazingly simple!
From the point of view of being in the motor trade for 40+ years,explaining stuff to customers or indeed other mechanics,fitters etc.my experience of people not understanding certain functions or operations seems to be primarily because they see a whole assembly and become overwhelmed,some just too thick to even understand basic principles😁 many people are much the same with wiring diagrams they see a page full of Criss crossing lines and it's all over!. Its better to break each part down into its component assemblies much like this diff,showing and explaining just the planetary and sun gears(the actual differential) and the CWP separately first, then combined makes it clearer for many. I will happily draw diagrams or even invite customers into the workshop to show them stuff first hand.Ive always believed it should be a fundamental of the driving test that you have at least some basic knowledge of how a car works before you are let loose in one,I don't expect people to perform their own clutch change but the ignorance of some motorists is staggering,sometimes dangerously so.
yeah, everything is difficult, before u understand its principle
The same statement applies in calculus too :P
I read your comment just as he said it XD
I really appreciate that they started explaining it by introducing a really basic version of the differential. Having the absolute simplest concept of things as a ground to stand on for our comprehension really makes everything easier to understand by people of all levels of intellect. I thoroughly enjoyed this.
Thats what happens when someone who truly understands how something works and is able to not only build it themselves but explain it to others.
And they show iteration by iteration how it evolves to close those gaps to the more "complex" system.
yeah, i feel like that's the most effective way to teach/explain something
Yeah I agree.
Seeing something in its full and finished version often overwhelms the mind. But if you see it step by step in a basic way, you can then move on from there with relative ease.
This is by far the best video on how a differential works.
For a video nearly 100 years old. It's really well made. Informative and interesting. I hope there are more videos from this same guy / series.
Crazy to think the 1930s are almost 100 years old
We tend to believe man was less creative in the past.
But the way of thinking of a man from the pyramid building time and a man nowadays, is exactly the same.
Same creativity, same inteligence.
The only thing that improved was the previous knowledge.
The problem when teaching things, is jumping basic concepts.
The more the teacher jumps, the more difficult to truly understand, no matter if it happened 4.000 years ago or nowadays. That is why we always had and will have good, and not good teachers.
The guys that wanted to teach how a transmission and a differential work in this video was a good teacher, with excellent didactic.
Absolutely love how their only two reasons they give as to why having a fast spinning driveshaft running through the cabin completely exposed is 'because it would be inconvenient for passengers' and 'would be awkward for carrying luggage'.
@the air accumulator It would be covered, a lot of new cars have that.
@the air accumulator " no idea, like catching your clothes or jewelry on it and getting a body part ripped to bits"
That would certainly be an inconvenience.
@EnderSpy007 which if the driveshaft broke would still turn into a propeller along with the broken drivshaft.
@the air accumulator Because people in the 80th didnt know what a casing is? 😉
@EnderSpy007 Now that's just boring, and quite silly. I prefer my cars being a workplace safety hazard.
я в шоке. сто лет назад сделали такое полноценное видео объясняющее ход мысли инженеров. браво
Потому что раньше не существовало маркетинга и рекламу делали создатели продуктов которые знают о чем говорят
@Илья Игнатов самое главное в этом обучающем фильме что его можно смотреть без знания языка и без субтитров, настолько всё понятно показана, и на столько хорошо построино повествование что тебе в колову приходят те же идеи по "апгрейду" демонстрационного устройства одновременно с показам оного
Благодарю, теперь для меня дифференциал это не просто запчасть страной формы
@Roman Koregin Да! Когда люди горели ИДЕЕЙ !!! Понимаю о чем ты... Натыкался на такие видосы... (Помню что то банальное,типа "Продление ресурса Грузовиков на производстве" 196? год вроде..)Но я был реально в "Ах.е"от подхода и отвецтвенности... Люди правда верили в "КАМУНИЗМ",и рвали спины на общее благо! Не понимая что это дорога была в Никуда....
These old explanation videos are so much more educational and easier to understand, I’ve learned how transmissions work, how differentials work and how to be a ww2 bomber gunner
😂😂😂😂😂
lol
I liked the barrel running tutorial in the end.
Today they just over complicate every day tasks
Same here
5:09 - Moment of enlightenment. I literally don't have words to explain how well made this video is - so much genuine effort went into this so that the explanation is as intuitive and easy-to-understand as possible!
@Xorberax No, no.. you should use the other word.
Inconceivable
I had the same reaction - made me almost feel stupid for not having grasped the concept before. Imagine the lateral thinking that went into designing that from first principles, though.
@American Plague Yeah like literally that annoys me like literally
@American Plague insufferable
Грамотная, поставленная речь. Очень приятно слушать. А ведь мало что изменилось в конструкции автомобиля с тех времен.
Forget about the differential, this is a masterpiece of education. Such an elegant and simple way of explaining this so that literally anyone on the planet could understand it. If schools were as good at teaching as this video is, the world would be full of geniuses
Кто ясно мыслит, тот ясно выражается! Никогда не знал как, это работает, за пять минут стало ясно с первого раза.
I really like how this is explained, it feels so much easier to understand than any modern lecture, text, or lesson.
@yara Rahman its the truth!
.....
I think the reason this explanation is so good is that it approaches the differential not only from a “ here is mechanically how it works” but a “ here’s the problem that each piece solves” as well.
yeah like they basically showed how the engineers solved it
@Sawta In reality, impact loading and number of teeth is handled seperately and are not directly related at all. In gears, the teeth are just made thicker if the number of teeth decreases. However, to account for assembly/manufacturing tolerances there is a small gap between meshing teeth called backlash(usually 50~200 microns in modern differential bevel gears) and this is the only rotational play which can cause impacts.
Impact on differential isn't much of a concern as it hardly accounts for 0.1% of a vehicle's life. Differential gears are designed completely with normal operation in mind and are simply tested at the very last stage to ensure that they can withstand certain number of impacts.
The only relation I can think of is that increasing teeth is better for impact simply because the impact wear will be distributed over more teeth, reducing its effect on each teeth.
@Sawta indeed, continues meshing of the gears prevents shock load and impacts. Shock load is when a part under high stress or no stress is suddenly accelerated. Which is why you can break a piece of spaghetti very easily but if you slowly and cautiously apply pressure to it, you can get it to flex quite a bit.
The space programs of the 50s-70s was mostly calculated by sliderules, those boys, and some women too were sharp. They were engineering students of life,physics, mechanical, chemical, metallurgical. No computers folks, in their minds,grappling with some heavy unknowns and they pulled it off. was a pleasure to be exposed to the last of them coming out of h.s.entering the workforce. Problem solving at an artform, the best education I could have gotten. Not so many specialists, some of them were amazingly versatile and wouldn't be stumped, not for long anyway. There stuff worked. I feel like a slouch now
See one of the best things about these old videos, is they're just plain honest. They weren't trying to peddle a product, promote a company or even themselves. Nowadays, even if a video exactly like this was made, we expect a hidden agenda, which almost always means: lying or giving "Technically true" statements, and our faith in the information is severely diminished.
And yes, you probably did just read that in the same voice and tone as the video.
It's so beautiful how they explained this,it's so clear and easier to visualize and understand.They don't make more like these nowadays
I am blown away with how simple and effective this video is, I didn't even know the rear wheels even moved at different speeds!
Yo tampoco
I've watched several animated videos before explaining the same stuff, but they never bothered to solve the problem using simple mechanics before, they straight up jumped into the gears and stuffs without explaining the basic solution upon which we can build more robust and complicated mechanisms, like this video did. It's excellent.
it has been really essential to start from the simplest context to understand how complicated structures work. and this video did it so well. i hope all teachers adapt this way of teaching.
Perfect education. Real knowledge is ability to explain complicated things in a simple way. People that made this film possible deserve the applause.
@frostonium
welcome
The Innate Nature in man recognizes what is good and bad, what is true and false. It recognizes that the Attributes of Allah must be True, Unique, and All-Perfect. It does not feel comfortable towards any kind of degradation of His Attributes not does it qualities to the Creator. Many who became “discontent with God” did so because of the practices of the Church in medieval Europe and because of the claims of “god dwelling in a son” and the concept of the “original sin”. However, they “escaped” into worshipping a new theory called “mother nature” as well as the “material” World. With the advancement of materialistic technology others from different religions adopted the concept of “forgetting about God” and “let us live this life and enjoy it!”, not realizing that they have chosen the worship of the “original god” of Rome: Desire!.
NOW we can see that all of this materialistic and secular progress produced a spiritual vacuum that led to complex social, economical, political, and psychological problems. Many of those who “fled” their “religions” are in search again. Some try to “escape” the complexity of their daily lives via various means. Those who had the chance to examine the Qur’an and Islam, proceed with a complete way of life that relates man to establish a purpose for his presence on earth. This is well recognized in the Attributes of Allah and what does He require from man. He does not want man to be enslaved to any false deity: nature, drugs, lust, money, other man, desire, or sex. He provides man with the proofs that He is the One who can redeem so that man can free himself from the slavery to any form of creation and to turn to his Creator Alone. THIS Creator Has Perfect Attributes. He is the First, nothing is before Him, the Ever Living. To Him is the Final Return where everyone will be dealt with in the Most Perfect and Just way. He does not begot nor He is begotten. Those who attribute Divinity to Jesus forget or ignore the fact that Jesus was in a mother’s womb. He needed nutrition; he was born and grew up to be a man. He was trusted with the Gospel as a Message to the Children of Israel: “For there is One God, and one mediator (i.e. a messenger) between God and men (the
Children of Israel), the man Christ Jesus) (I Timothy 2:5). A man-messenger calling his nation not to worship him: “But in vain they do worship me!” (Mathew 15:9). A man who needs to eat, walk, sleed, rest, etc.. cannot have Divine Attributes because he is in need and God (Allah) is Self-Sufficient.

they are dead
What is really amazing is exactly how this was brought into reality. How do you prototype this kind of system, how do you industrialize it. With everything tedious related: the engineering tolerances, the inevitable wear and points of failure. This appears robust. Great job.
I'm a layman, but even I got hooked into the demonstration. Amazing job. Keep it up
There are so many cool feats of engineering by men and this one is always something I appreciate.
You know what I appreciate about old videos? They are always clear, and they actually know how to explain stuff that they clearly understood.
@krvnjrcbs Exactly.
@Sheep picks its nose Even just old dictionaries they seem more clear and straightforward, no fear of offending, just telling it as it is. Maybe the best old stuff were preserved and we aren't given the whole picture, but in general they just seem better.
They also always have a lot of wind instruments.
Otherwise you're just biased.
It's a clear case of survivors bias: there are even more good video guides nowdays than back then, but bad old ones were forgotten, while good ones were not.
Ease of production sure adds to this, nowdays every bum can shoot a crapshoot and post it here, in 1930's it was more expensive, thus more effort was put on average.
I love watching these types of videos- they teach you with simplicity and in a way everyone will understand
83 years later, still no animation can beat this.
Is that a real old video ?
What a jool
you literally could animate this 1:1
Real
85
Es- ti-ef-yu
This is one of the best simple explanations of how a gear works and how we got to that design that I've ever seen, even though the video isn't really about gear design.
I've been learning so much from these videos sinc the one about manual transmisions popped up a couple weeks ago. Thank you to the folks who created these 85 years ago!
I love these old BnW shows, they're informative and has some iconic aesthetic plus the unnecessarily long but cool intro
Curious how they didn't think about front wheel drive until later when it came to drive shaft placement. Goes to show that innovation and engineering in an iterative process of just making things slightly better.
The fact that they did all those stunts on semi bumpy dirt and not a pavement or asphalt road makes it that much more impressive
*"...But once we understand its' principal, it's amazingly simple!"* And this video explains it amazingly and simple! Great job, 1937! 🤯
@Stephen Dias nope
@Eðin Hvassur irrelevant
Me too, what sorcery is this!?
Yes!
I love this kind of thing. It's amazing to see humanity have a problem and try and fix it and even make it better. always striving for progress.
This video is awesome, seeing an old 20th century explanation on the mechanisms of a car is so fascinating.
These ancient videos are still as relevant now as when they were made. The basic fundamentals haven’t changed, and usually they are very clear and easy to understand.
Think about it. Some machinist, probably in Michigan, worked on making all of this beautiful metal in conjunction with engineers and script writer. It's really impressive.
The presentation it's absolutely incredible. Because of its simplicity for the target audience.
Well done
I am an engineering major in my third year. Never have I ever had such a thorough explanation of a concept.
Screw modern education
What yall think about Lincoln tech?
And the self-inflated egos that teach it...
The reason modern education tends to be different is that the rate of evolution of technology has now exceeded our ability to teach it to someone before what we're teaching is obsolete. Instead, we must teach people how to learn, so they may continue learning at a rapid pace throughout their entire career.
...which reminds me, I have exploded magnets to clean up in the kitchen. My girlfriend's Christmas present isn't going to build itself, and god help her if she's counting on *me* to build it, apparently...
This explanation could be strung out over a week all for the £$.
Never knew about thisuntil today. If it was by today's standards, I'd be seeing ads in front of the gears asking if I want a new GM car.
Great learning video. Simple, clear, and starts off easy and then gradually shows the actual engineered design.
I like this explanation because I believe the sticks model is how Archimedes extended his principals of Levers into multiple continuous levers now known as "gears". With that he then constructed the antikythera mechanism and with his principals we have constructed the world as we know it.
85 years later, It's still the clearest explanation about how a differential works you can find.
I love this. So well and clearly explained.
I love how they showed the technology progress. These videos should be made today
Almost a 100 years later, this explanation is still phenomenal. These engineers/scientist were way ahead of their times.
Yea meanwhile me over in 2022 take an hour to find a site with actual information that actually teach me the straightforward point I need
I am like 90% sure my car from the mid 80's still uses more or less the same thing just with a tweak or two if that.
@DarkShadowsX5 It was white excellence.
They were not ahead, humanity just keeps on regressing and focusing on bs instead of important matters.
How can they be ahead of their time because of a creation that was invented and used during their time? That phrase only applies when people theorize something that eventually will be in use in their future.
I love how they went to the trouble of actually running a driveshaft through the cab of a car to demonstrate how inconvenient it would be.
definitely one of those things that are taken for granted. yet someone had to sit and plan it out for hours to be so good its still used today.
who would have thought that I'd learn a whole lot from something that was produced almost a century ago, this guy deserved some kind of award...
It's interesting what advertising used to be. Like there was some hope in educating their customers.
WOW I am genuinely surprised. This was way better than what I expected.
Never fails to make me smile. Everything about this video is wholesome and cool.
This is great
It doesn't just explain how it works, it also explains why a differential was necessary in the first place and does it with simplicity 👍😉
@xtlm challenge accepted. Sam o'Nella academy has videos under ten minutes.
@topdeck55 True enough but not the point. I'd like to see how it works in comparison. Doesn't matter when it was invented in relation to this film.
@Nick H The limited slip diff was only race car technology at the time. It didn't get to production cars until after WW2
@xtlm action lab
@Nick H I believe open-type differential were either the only type, or the most common differential at the time this video was made.
As you said, open-type differentials are fine for spinning on roads, but still a issue when driving on bumpy roads or off-road.
This video blew my mind. Love seeing the science, but also the presentation is perfection!
Better than most videos nowadays..... Such detailed explanation in a very simple way without extra long useless talking
Very very good. An absolute joy to go through this.
Love these old videos, you get to understand the whole tho process that led to the final product.
Love these old educational films. So well done.
Its amazing how these people back in the day where able to make high quality videos like these with animations, transitions, and overlays with little to no computer power. Its also pretty interesting how a video from the late 30's is still relevant today
That is a FILM, not a video, and film is much more difficult to work with.
Just good editing back in the days when you had a reel of film, a razor, and tape.
This is still a better explanation than I got when actually in auto tech school.
old teaching videos are the absolute best! I continue to learn things from these videos and it's great!
En basit ve etkili düşüncenin, mükemmel hale gelişinin videosu. Harika. Keşke insanlık dehasını Manyetizma içinde kullansaydı.
Still my favourite video on this subject. Hope it stays forever!
Bonita explicacion, hasta ahora entiendo bien como funciona un diferencial. Muchas gracias por instruirnos
Who would've thought that this will be useful (and exceptional) after so many years. Good job to the team that made this, it's simply faultless.
Equim i would like your comment but it's currently at 69
edit (2 seconds later) well it just hit 70
so nvm
yes, the authors are apparently dead, but their work lives.
This video from 1937 does a better job of explaining things than anything other than Bill Nye does today.
I’ve always wondered how it works. Glad we got to learn :)
85 years later this video still teaches people well about cars
Education at it's finest. Starts simple and then builds complexity over time.
This is such an exemplary way to explain a difficult mechanical concept.
I've studied mechanical engineering and was never shown as clear a video on differentials principles as this one
clip-share.net/video/58zdJmumcdA/video.html وهذا الشرح بالعربى
@The Sethioz Project u do know all this modern stuff like Google is made by people
@The Sethioz Project Why is "I don't know" a bad answer? Admitting that you don't know something is a good thing as opposed to simply spewing bullshit. And no, average IQ is steadily increasing by around 3 points a decade.
And when you say "clicking away," I don't think you realize how many different things that could be. Sometimes I get a random question about math or science and I look it up. Sometimes I'm texting a friend that I haven't seen in a decade. Sometimes I'm posting some tips on how to do something on reddit. It's about as heinus as generalizing all people in 1937 as "just staring at their televisions."
@The Sethioz Project I totally agree with you brother👍👍
@The Sethioz Project People were always dumb. They weren't smarter back then, they had to rely on others who had the luck to know someone who could teach them. Just like now, the smart people back then were only smart because they made use of the knowledge at their disposal and attempted to learn. Have you ever talked to an old person? Half of them don't even know how to use a phone, or a computer, or fix a single thing in a modern car.
I really enjoyed this demonstration its so much easier to learn with the 90s videos than today's century
I can imagine myself watching this in a 1930's theater and how awesome it would be
I LOVED this! Wish they showed stuff like this in school! Thanks!
I’ve watched this too many times. In my pursuit of ASMR, I now know how differential gears work, simple, elegant.
I love these because they were explaining to a population who may not have had the educations today we deem 'basic'. So, naturally they're easier for us.
Complicated is nothing when you have a good teacher.
exactly
Well... there are still complicated things. But yes, a good teacher/explanation makes all the difference.
It isn't complicated though
@Domino Pizza а вот и тролль проявился...
Such a great video. I'd be impressed with the visuals if someone made this today
How he gets from the spokes to the gears is like Sokrates making a point. You can't help but follow 💟
This is a nice simple demonstration of motorcycle safety from the good old days.
this is a pinnacle of explaining things. building up complexity from the simplicity
My Auto Tech teacher showed our class this and he said this was the easiest explanation ever about how a differential works. Man was he right.
@Adam Adam I just watch explanation videos in general and have to say that this is probably the best explanation of something ever besides maybe the video by 3Blue1Brown about how colliding blocks spit out pi.
Ollie Foxx I did. It was a semester class of this year (2020). I wish I could’ve stayed for more.
i wish my teacher would have done the same, altough some people in my class don't understand english.
Very cool teacher. Bet you learned alot
@Adam Adam Perhaps is the best video any has seen...
Melhor esplicacao de mecânica que já vi desse jeito aprendo até física quantica
I surprise that such interesting and easy-understanding movie has existed in 1930s. It is great idea that explaining things from simple architecture into realistic but complex thing. I like this.
This is actually what the inventor of the TV had in mind. Makes me want to take a time machine and go back. 🥺 Simple life is a happy life.
very informative and easy to understand. better explanation than this time, ever!
This old video is so simple and educational, then videos now. So simple explanation and you 'll not break your brain. And you 'll not spend a lot of time like "how does it work? I don't understand it"
it is disturbing how informative and easy to understand that was, relative to more modern edu-tainment crap we have now.....

The reason this has i much info is because people didn’t have the internet and if you were watchin this vid back then it was because you didn’t know anything about it no a days people are extremely impatient and hate learning shit they already know so people have to teach others without saying info that is easy to find on google there for leaving out info
There’s still a lot of good edu-tainment videos out there, like anything by Kurzgesagt, Vsauce, Veratasium, and 3Blue1Brown. You just have to look for it.
@Fudge Shizzles First, lets be fair. School does not 'make you' work for someone else. That's what most people do, because working for yourself is extremely hard.
But I would say that school is now more about making money, than education. And there are two reasons.
One reason is because of students. The reason why so many schools have garbage degrees like Gender-studies, is because hard sciences are hard. Learning gender studies is easy. And we have for some reason, taught people that just getting a degree makes them money, instead of teaching them that learning a school that has market value, makes them money.
And the second reason is government. Government has subsidized, and guaranteed loans for bad students, to get useless degrees. If universities had to compete with each other on price, they would be finding ways to reduce costs. Just like stores compete with each other over customers by lowering prices, schools would compete with each other for students by having lower prices.
Instead universities spend millions having a yoga center, and climbing wall, and all kinds of ridiculous things. Go look up John Stossel Rising cost of college. All the luxuries that colleges offer, cost money, and that requires higher tuition fees.
That explanation is transparent. Very well done.
Someone said you can easily understand a complex issue once you reduce it to its principles. This movie is spot on on exemplifying this statement.
Sensacional demais!!!!
It’s easy to forgot the amazingness of human ingenuity.
Some simple yet ingenious ideas even from 100 years ago.
Hell, even a gun is complicatedly interesting to see how it works
They really knew how to explain things clearly back then.
The differential is a piece of engineering that looks so damn complicated but the principles behind it are astonishingly simple. The person who thought about it for the first time must have been a freaking genius.
Btw this 70 yo video is the only one I've ever found that explains it in its pure simplicity and genius.
His name was Onésiphore Pecqueur, he was french, and he invented it before cars existed (He died 30 years before the first car ever was built). It was originally used on mechanical watches to allow two gears on the same axis to rotate at different speeds.
The creativity of old watchmakers is always mindblowing
It was invented by the Chinese for ceremonial reasons or to instill awe in the simple subjects . On a cart a statue would always point in same direction when the cart turned a corner .
@Simple Simon Some 90's cars have literally the same differential
Well, remember that technology was also simpler back then
This is the best education video I have ever seen.
We need more videos like this about many more things!
Efsane anlatım. Şunu öğrenmek gerek bu video sonunda. Bir şeyi anlamak için olabildiğince temel düzeye indirirseniz sizden daha iyi anlayan biri çıkmayacaktır.
Almost 100 years later and not much has really changed with a differential
I learned more on this video than in my 5 years in college studying mechanical engineering.
I wish modern educational videos were still like this. I could watch phone book explained if it was made in this artistic style.
Practical, applied engineering at its finest. I'd watch an entire catalog of these videos if they where available.
@ILHillbilly67 or auto shop... something you would have to attend a technical school for now
I think these were used as fillers in between movies at he local cinemas???
check the channel that uploaded it lol
these videos are so simple and explanatory that even a 5 year old could understand how these work because of how simple they explain it. it goes to show how something so simple has become complex over the years but the principle is still the same as it was back then
I love it. The 1937 voice is great, too: so entertaining and satisfying to watch.
this is not only classic, but also intuitive.
