Differential with torque coupling

摘要

A torque coupling unit (12) for use with a differential assembly (10) is provided. The torque coupling unit comprises a first member (48), a second member (58), a clutching assembly, and a clutch actuator (76). The first member (48) is in driving engagement with a side gear (30) of the differential assembly. The second member (58) is in driving engagement with an output shaft (18). The clutch actuator assembly (76) is disposed adjacent the clutching assembly and comprises a roller and ramp assembly (82). In response to a rotation of a portion of the clutch actuator assembly a portion of the roller and ramp assembly is driven in an axial manner to apply a force to the clutching assembly, causing a first portion of the clutching assembly to be at least variably frictionally engaged with a second portion of the clutching assembly.
