DIFFERENTIALS | How They Work

The Differential is one of the most important parts of your car’s drivetrain. It ensures that power is equally distributed to the wheels, even around tight turns! So how does it work? Join Bart as he explains the complicated mechanics of Differentials
Bart teaches us how cars work by blowing stuff up and cutting things in half. It’s a science show for the car lover who’s easily bored. Join Bart as he explains the science behind everything automotive. This is cars down to the atom. This is Science Garage.
Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

I thank you for starting this KZbin channel.. I started watching today and I love the information y'all are giving me about cars and how they work. Keep up the good work 💯🖖👌⛽

[@peyn]

It's important to note that clutch packs are pressed together by the preload spring and axial forces (the faster the driveshaft/axle spins, the harder they're pressed together). When they are not spinning fast, the clutch packs are allowed to slip thus the differential acts as if it's open, hence "limited slip".

[@scotthenrie5674]

Oh! Thanks, he should read the useful comments and include extra or missing info in a follow-up video.

[@aklip]

Good info but you skipped helical gear style LSDs like a Torsen

[@insanetaco98]

[@colebaranek4604]

[@darius2640]

can an open diff spin both wheels when you do a straight line burnout of is it always have to be one wheel peel?

[@rangerover06sc]

Yes an open diff can spin both wheels as long as both wheels have about the same traction. But if suddenly there is a large enough difference in traction only one wheel will spin.
