Abstract
A transfer case system distributes torque between primary and secondary drive trains. The system comprises a planetary gear set having a sun gear, a ring gear, a planetary gear intermeshed with the sun gear and ring gear, and a planetary carrier rotatably connected with the planetary gear. The system also comprises a torque sink connected with the sun gear and a torque input shaft connected with the ring gear and the primary drive train. The torque sink applies a braking force to the rotation of the sun gear in response to instructions from a controller, causing the ring gear to output torque to a secondary drive train.
