ABSTRACT:
A differential drive unit has separate drive shafts extending from a housing. Respective drive plates for each shaft differentially receive rotational power from the housing as such housing rotates. Respective wedges transfer housing rotational power to the respective drive plates, upon engaging inside diameter portions of the housing. Such engagement forces the respective wedges down into contact and frictional engagement with one of the respective drive plates axially inward therefrom. The wedges are carried in circumferential slots defined through the circumference of a cage assembly, which includes an annular member located between the outside diameter of the drive plates and the inside diameter of the housing. Wedges within a given slot include a pair of wedge elements joined together with a spring under compression. Free-wheeling of a drive shaft speed is permitted whenever its respective drive plate, rotating at a speed faster than the housing, advances a trailing wedge element of a pair out of engagement with the housing engagement areas by compressing the corresponding spring between such pair of elements. Such free-wheeling does not affect drive engagement of the other drive plate, which continues to be driven so long as it is rotating at the same or a slower speed than the housing because a wedge member longitudinally aligned with such other drive plate continues to transfer rotational drive power thereto from the housing.
