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