Abstract
Positive acting differentials of the type having drivers driven in rotation by a pinion pin and couplers coupled to the axles of a vehicle, the drivers and couplers having facingly disposed teeth forced into engagement when the pinion pin is driving the respective driver or drivers by forcibly contacting the same at an angle. The teeth on the drivers or couplers or both in the present invention have a chamfer on the outer part of the teeth in comparison to the base region of the teeth, so that the facingly disposed teeth on the drivers and couplers are forced into engagement when the base regions of the teeth are engaging and the pinion pin is driving the respective driver or drivers by forcibly contacting the same at an angle, but the teeth on the drivers and couplers will only climb each other when the outer regions of the teeth are engaging and the pinion pin is driving the respective driver or drivers. A preferred and an alternate embodiment are disclosed.
