Around the corner, how a differential works

(9:31) Excellent tutorial from the 30's on the principles and development of the differential gear.

BUT!!! Notice that when one wheel is stopped you can see the centre pivot moving at half the speed (rpm) of the free wheel. When both are moving the centre pivot was moving at the same speed (rpm). EXPLAIN THAT!

You can clearly see how it occurs, surely that is explanation enough?

Latest comment: No Mr Sensible, what I am seeing is the axil of the centre pivot moving at the same speed (rpm) of both tires (when both tires can move). However, when one wheel is locked the centre pivot moves at about half the rpm of the free wheel. This would mean that if the centre pivot is powered at a constant rotation then as one wheel is stopped the other will accelerate. I always assumed that a differential maintains a constant ratio between the drive shaft and at least one wheel. Or is that actually how it happens? ie the drive shaft rpm is altered slightly during cornering by a ratio determined by both the gear size of the centre pivot and the length of wheel base?

The center pivot moves at a constant rate, so when one wheel stops completely, all the motion is transferred to the other wheel via the rotation of the gears attached to the pivot.

Excellent, a bit of a slow starter but worth it for the simplicity of the explanation.
