Torque split type automatic transmission

摘要

A torque split type automatic transmission which transmits torque output from an engine through two paths, adds the torque passing through and increased in each path, and outputs a final torque, may be provided wherein the torque of the engine is dividedly transmitted to first and second power delivery paths, a launching device for converting the torque and a transmission device for achieving multiple-shift are disposed on the first power delivery path in series, and a torque combining device is disposed on the second power delivery path, and wherein the first power delivery path is connected to the torque combining device such that output torque of the first power delivery path is added to output torque of the second output path to output the final torque.

1. A torque split type automatic transmission, which transmits a torque output from an engine through two paths, adds first and second torques that pass through the two paths respectively and that are increased in each path, and outputs a final torque,
wherein the torque of the engine is dividedly transmitted to first and second power delivery paths forming the two paths, wherein a launching device for continuously receiving and converting the first torque and a transmission device for achieving multiple-shifts are disposed on the first power delivery path in series, wherein a torque combining device is disposed on the second power delivery path and continuously receives the second torque, and wherein the first power delivery path is connected to the torque combining device such that output torque of the first power delivery path is added to output torque of the second power delivery path to output the final torque, wherein the second torque transmitted through the second power delivery path is larger than the first torque transmitted through the first power delivery path.
