Which way the gear will turn is a matter of a pinion.

At 5:17 it mentions the camshaft, but this is not correct, this is a CRANKSHAFT. The crankshaft transfers power to the drivetrain, the camshaft controls the opening and closing of the valves so that the intake and exhaust strokes are timed properly.

Very good, worth pointing out that the clutch pack can be adjusted so that it grips with different torque profiles. The differential is really an extension of the steering system, conceptually.

Thanks for the engineering lecture, and much love!!!

crank shaft not cam shaft and drive shaft is arguably a prop shaft. Drive shaft would be straight from gearbox to front wheels in a fwd car - or driveshaft is from diff to wheels in a fully independent suspension rear drive car. In a live “axle” setup as per this video - its axle shaft from diff to wheel and prop shaft from gearbox to diff

This is beyond describable. You're an absolute legend! Our huge pleasure to work with you 🤟

Just watched a video explaining the differential back in the 30s or so. And now this. Nice

Amazing video. I'm super fascinated by this. I wanted to learn how cars work for so long, but didn't know there are videos explaining car mechanics as in debt as these videos do. Great! I'll be coming back here often. That's for sure!

We've got a lot to learn from this

this channel is prob the best at integrating promotional materials into video imo

Learned and understood a lot more than many textbooks 👍

Thank you. Thank you very much. This'll save lots of time and stress on other subjects. Thank you

Videos like these is the reason why current EVs should be best understood with respect to FWD/RWD and AWD. It's not always a good idea to just jump straight to AWD (e.g. buying M3LR), knowing the drive motor, albeit computer controlled, should not be a substitute for tried-true mechanical understanding.

Very good explanation. Limited slip or positraction diffs are good but can get you into trouble. Ask me how I know! Air or electrical locking differentials are much better and give you the option to run an open diff or a "locked" diff. There's also another way which is using the ABS to intermittently apply and release the brake at the slipping wheel and allow the diff to apply more power to the non slipping wheel. You still have an open diff but when needed the ABS system gives you that "limited slip" feature. I have the ARB Air Locker in my Nissan Frontier 4X4's rear diff. Works great!

I really like the animations... Easy to understand.... More videos..!!!!

It feels weird to say, I'm so stressed out, and this video was super relaxing and informative.

The clutch pack operates by pure friction? Then how are the textured surfaces not ground smooth by the forces involved? Or is the spring precise enough in compressing the plates for that? If so, that is some very clever engineering. Very impressive

I paused to ensure i dont forget to subscribe. Fantastic vid!

One thing that was not mentioned is that when the wheel with less traction begins to spin, an outward force on the spur gears is generated due to attempting to spin the low traction wheel, this force will further lock the clutches, the spring alone won’t create enough force on its own. All bevel gears create an outward force when load is applied.

I never knew about slip in an open diff. I remember wondering years ago why a stick car suddenly acts like it's 1 wheel drive.

It is very informative and we learn a lot doing practicals based on your video

Hello sir, can you please make a video on Drone controller circuit and its programming.

i’ve been waiting for your automatic transmission and rotary injection pumps explanation because no one can explain clearly as you do. i hope you’ll make soon.

Huzzah - what a great lesson

Spiral cut gears in the diff. also allow the input shaft to be positioned at a tangent to the diff, instead of having the axis meet. This allows for cars with lower floors.

Huzzah Good video, thank you♥️

Who came up with this? What a genius!

Incredibly informative video. Thank you.

The best video I've seen regarding differentials so far.... ❤️❤️... Btw can u do another video on how a Torsen differential works ❤️

Thank you very much for the video you made, which gave me a new understanding of the principle of differentials, a problem that has troubled me for a long time. I would like to discuss the following issues with the author and fellow fans: Suppose I install motors with sufficient power on the left and right wheels respectively, so that they can mesh with the star gear and rotate in opposite directions when the differential housing and ring gear are stationary (that is, the transmission shaft does not rotate), Is this possible? If possible, does that mean assuming the differential housing and ring gear are rotating at 100RPM clockwise, when the left wheel (left side gear) is rotating at 200RPM counterclockwise, the right wheel (right side gear) Will it rotate clockwise at 300RPM? Modified (2024.2.9) After thinking about it for a long time today, I have a new understanding of this problem. Now I think that assuming that the left wheel (left side gear) rotates forward at 200RPM, when the differential housing and ring gear rotate forward at 100RPM, the right wheel (right side gear) should be at 0RPM Because when the left quadrant point of the star gear (i.e., the point of mesh with the side gear) rotates forward, the right quadrant point of the star gear (i.e., the point of mesh with the other side gear) will rotate backward, so the connecting star The speed of the differential housing and ring gear of the gear should be half of the speed difference between the left wheel (left side gear) and the right wheel (right side gear). For example, the left wheel rotates forward at 500RPM and the right wheel rotates forward at 100RPM. The differential speed The speed of the motor housing and ring gear should be 300RPM forward. Do you think my understanding is correct?

very Great explanation. ‪ ‏‪4:01‬‏ I do not think that gear ratios have anything to do with “ increasing ” fuel consumption. Above all, they are a Mechanical Advantage.

Great instructional videos. Thank you. Great info.

Thanks I always learn something new from your video. Keep it up

Well done! This helped me!

great video. some minor errors but the concept is great!

I enjoyed that and more importantly thanks for the knowledge.

Great video as always. Is there an instruction sheet that goes along with the 3D print model for assembly?

Crank shaft, not cam shaft

As a small child I learned the working of a dif from lego technics.

Thanks for such a nice video explaining differential in detail. Could you please explain how it would be with LSD, when car travels on a slippery surface while taking a turn? i.e combining the two scenario you have explained. Thanks

Solid Visuals!

Can you please make a video about a powerplant steam turbine generator. I love your channel. all the way from South Africa.

thanks for the great afrod in every video

I'm not watching this for school I'm watching this because I fuckign love engineering

Awesome video, thank you!

In the animation, the pistons are directly causing the crankshaft to rotate, not the camshaft. Cams cause valves to open and close.

@5:29 the crankshaft not the camshaft. Small error but I love the video

The pistons rotates the crankshaft and not the camshaft. Note that the spiral drive gear is not centered with the ring gear like the straight ones for mechanical reasons that provide better transmission.

great video as always, i learned a lot from you

Apakah aman jika diferential kita las dan apa kelebihan nya jika di las dan kekurangannya jika diferential di las

thank you for this video appreciated much💜

Please can you guys make a video or playlist on smart energy meters, really need it for my final year project, thanks

Good channel for sharing knowledge

I have been thinking of a 3d printed wind fence design, where lots of small (100 - 150cm high) vertical wind turbines applies torque to a common drive shaft, that then later goes into an electric motor to generate electricity. The idea is to make it easy to 3d print at home, and reduce amount of expensive components. Since you only need etc 1 motor for lets say 10 small vertical wind turbines connected in serial. One question comes to mind is how to make each turbine apply their share of torque to the drive shaft, considering some might catch more wind and spin faster than on the other end on the fence. I need some sort of gear that turns horizontal torque into vertical torque, but not the other way around. (so busy turbines dont spin up the lazy turbines).

Great Vedio as Always, Can we please get a detailed explanation of transistor amplifier circuits next please?

I'm missing a trick here at 7.20 it looks like the left side gear isn't meshed with the spider gears?

Does deceleration(increase torque and decrease revolution) always happen in the differential?

Thanks for this.

Fun fact the ratio of pinion to ring is 11:43, just 1 tooth short on the ring gear to make it a perfect ratio. Why? Because it's a hunting gear set, so named as the pinion hunts for it's original starting tooth engagement as it rotates. This is done on purpose to maximise wear life of the gears and is achieved by making the tooth count a prime number.

I 120% know how a diff works, but yet I'm here watching this video 😆

I'd swear that's a crank shaft not cam shaft.

Limited slips also can wear out or lock when going around a slick corner causing the rear to slide out.

Hey would you be willing to do a video on how to make a charge indicator?

Please make a video about the radio and how it works.

Hey man, can you make a video about fuel injection pumps explained ?

Change brakes on rear wheel drive vehicle 2010 doge charger 3.5. Had it in the air and put in the drive. Driver wheel is spinning and passenger rear wasent spinning is that normal?

You've explained how the clutch pack allows the axles to rotate at different speeds in a turn: The mere force of the different turning speeds from the wheels causes the disks to slip past the plates (I suppose by overcoming the amount of friction at the plates created by the spring). But you haven't explained the clutch pack causes the power, when one wheel encounters ice, to transfer to the other axle. Like most lsd videos, you've simply declared at the end that it does without explaining how. How does one side's clutch plates slipping prevent power from still being transferred to that side's side gear? If the open diff allows the side gears at any and all different rates, what prevents the gripping side from stopping while the slipping side takes all the power? In other words, what you've explained is how the point of slippage moves from the tire-ice contact point to the disk-plate contact point, but you haven't shown how that changes anything on the diff/opposite axle of the slipping side's clutch pack. Why would the diff act any differently on (i.e., transfer more power to) side gear B when side A is slipping? The ice situation is opposite the turning situation force-wise-- turning (assuming traction) resists axle rotation on the inside wheel relative to the outside wheel, but ice does the opposite, allowing freer rotation to the slipping side. You've explained the operation of the clutch pack in turning (where it isn't needed anyway since an open diff does that job), but you haven't explained how the clutch pack operates in the opposite condition-- ice allowing a wheel to spin freely. In other words, the difference a clutch pack makes is allowing an axle to be free (somewhat at least) of the side gear, whereas in an open diff it never is. But in an ice situation, so what? Friction is already freed, just farther out (where tire meets road). What removes power from the slipping side's side gear?

For the question at the beginning of the video, the gear indicated should rotate toward the camera.

Thanks!

Excellent

The engine delivers power through the crankshaft, not the camshaft. Your illustration is of a crankshaft but it is mislabeled/misidentified.

Thank you so much

Please make a video on "how signal jammer works".

Could you please share the 3D model for differential?

Would be helpful if you could do a video on Dident types of fire cable runs eg alalog

I have a doubt, not related to this.......when i connect a small dc mortor to a 9v battery............And it works properly. But what happens if i stop the propellor from rotating, letting the current flow(i guess).

Could you explain how this would work if the car was put in park?

ok so like how difficult is it to install lsd on a car that does not come with lsd or has no product designed to fit it? Like an AWD G37x. Should it not be easy to accomplish? The car can just be switched to RWD on the fly so I really want lsd ... ?

Can you plz make a video for clutch??? ❤️❤️❤️

Thank you

Plz make a video on how rf transmetre & reciver work🙏🙏🙏🙏🙏🙏

Do a video on power line communication and smart meter

Thanks 💟

Please talk about single phase alternating current

CRANKSHAFT is what is driven by the pistons!

Tyer STL file is 140MB, is it correct file?

thanks

At 00:05:17 I think you meant the crankshaft NOT the camshaft.

This is insane, how did anybody figure this out, like the first time

So if this is true and it'll make up for slipping and lack of turning why when you have all wheel drive car and you blow out one tire they shop wants you to always replace all four?? I've read why before but after watching this video it seems like the car knows how to make up the difference

You've made cool video, unfortunatelly packed fully with advertisemets, both external and internal. Your videos will defend itself. You don't need to pack internal advertisements, which makes my - and probably some other's perception of your video bad. Keep doing good job, don't include internal advertisements. Best regards.

Pistons are connected to the crankshaft not the camshaft.

Hi there. At 00:02:12 if you lock both whells and turn the axle with your left hand as you do in the video, does anything turn at all? I am having a hard time visualizing it. Thank you!

Any gear meshed together will turn in opposite direction

I did think how the answer to the diff spider gear rotation, is variable to the conditions LOL.

on 4wd cars isnt there also a diff between the front and rear diffs?

1) Towards us

the only incorrect thing is accidently saying the shaft that holds the crankshaft is the camshaft

Plzz, make video on crystal oscillators. Plzzzzzzzzzzzzzzzzzzzzzzz
