Torque transfer assembly with planetary differential

摘要

A torque transfer assembly including an input gear, a first output shaft, a second output shaft, a planetary differential and a torque control system. In one embodiment, the planetary differential includes first and second planetary gear set pairs each with inner and outer planetary gear sets. The torque control system includes first and second torque control mechanisms each having a control element rotating with one of the planetary gear set components as well as a controller communicating with the first and second control mechanisms and selectively controlling a resistance torque exerted by the first and second torque control mechanisms on the first and second control elements. In another embodiment, the torque control system includes a hydraulic control arrangement hydraulically intercoupling the first and second torque control mechanisms and a controller operable to selectively control the direction and amount of fluid flow in the hydraulic control arrangement and the resistance torque exerted by the first and second torque control mechanisms.
