Differential explained - How differential works open, limited slip

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.

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

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.

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

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

We've got a lot to learn from this

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!

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

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

Learned and understood a lot more than many textbooks 👍

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.

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!

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

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

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.

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

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
