Abstract:
1. A torque split type automatic transmission which transmits a torque output from an engine through two paths, increases the torque in each of the two paths, adds the increased torques passing through each of the two paths, and outputs a final torque; wherein the torque of the engine is divided into two portions and each portion of the torque is transmitted respectively through first and second power delivery paths which form the two paths; wherein the first power delivery path is connected to a launching device, the second power delivery path is connected to a transmission device, and outputs of the launching device and the transmission device are independently met at a torque combining device such that each for torque increased through each power delivery path is added and the final torque is output through the torque combining device; wherein a torque transmitted through the first power delivery path is larger than a torque transmitted through the second power delivery path; and wherein the transmission device connected to the second power delivery path is a multiple-shift transmission device comprising a plurality of planetary gear sets, clutches, and brakes.
