Patent ID: 8888640

Claim:
A torque split type automatic transmission which transmits a torque output from an engine through two paths, adds each torque passing through and being increased in each path, and outputs a final torque, wherein the torque of the engine is divided into two portions by a torque split device and each portion of the torque is transmitted respectively to first and second power delivery paths of the two paths, wherein the first power delivery path is operably connected to a driving wheel via a transfer shaft, wherein the second power delivery path is provided with a launching device and a transmission device disposed in series so as to increase the torque passing through the second power delivery path, and output of the transmission device on the second power delivery path is directly added to the torque of the first power delivery path via the transfer shaft to output the final torque, and wherein the torque split device is not directly connected to the transmission device, and wherein the first power delivery path completely bypasses the launching device and the transmission device to the transfer shaft.
