Video of how a differential works

Have you every wondered what exactly is going on in a differential? When turning, how is one wheel able to turn faster than the other? What are the limitations? How does a limited slip differential work, and are there drawbacks?

This University of Toyota videos starts with the basics using some excellent graphical animations to show exactly what’s going on. It explains what is meant by the differential (or final drive) ratio, the components (ring, pinion, and spider gears), limited slip differentials (LSD), locking differentials, and brake activated LSD’s. Irrespective of your knowledge, you will probably learn something in this 4 minute video.

Kudos to Toyota.
