Believe us, even it is a century old tutorial it explains the functioning of the steering differential so well that after you’ve watched you will thought that you are an experts in mechanics! Yeah, old-school studying!
The short documentary film entitled Around The Corner which was filmed by Chevrolet in 1937, tried to make a clear parallel with the one-wheel drive system and made the tutorial beginning with synchronized motorcycle ride which is explained like dedicated team work and a lot of drilling.
After that follows the explanation of the need to connect the both wheels on the rear axle to spin but independently. That way they will eliminate the sliding on one of the wheels and send the one-wheel drive into history. On this problem were working the engineers to improve the car performances. The great invention which follows their efforts of improving the performances and independent wheels spinning on the rear axle is the differential.
At first view the differential looks complicated but once you’ve understand its principles you will see that it is amazingly simple. In the video you will see very simple and amazing explanation how the differentials work.
Don’t forget to tell us what you think about this tutorial, we bet that you would like it.
