Automated manual transmission with dynamic torque transfer device

摘要

A transmission system includes an input that is operable to receive torque, and a multi-speed gear train including a final output for transferring torque to a final drive. A clutch interconnects the input and the multi-speed gear train. When disposed in an engaged position, the clutch connects the input and the final output in torque communication therebetween. When disposed in a disengaged position, the clutch disconnects torque communication between the input and the final output. A dual planetary torque transfer device, which includes a pair of planetary gear trains coupled together, and interconnects the input and the final output. The dual planetary torque transfer device is disposed in a parallel relationship with the clutch, between the input and the final output. The dual planetary torque transfer device transfers torque between the input and the final output when the clutch is disposed in the disengaged position.

主权项

1. A transmission system for a vehicle, the transmission system comprising:
an input operable to receive torque from a power source; a final output operable to transmit torque to a final drive; a clutch interconnecting the input and the final output, wherein the clutch is moveable between an engaged position connecting the input and the final output in torque communication therebetween, and a disengaged position disconnecting torque communication between the input and the final output; a dual planetary torque transfer device interconnecting the input and the final output, and disposed in a parallel relationship with the clutch between the input and the final output, wherein the dual planetary torque transfer device transfers torque between the input and the final output when the clutch is disposed in the disengaged positions; a speed control mechanism interconnecting the dual planetary torque transfer device and the final output; wherein the speed control mechanism includes one of a gear train, a planetary gear train, or a continuously variable transmission; wherein the speed control mechanism includes a gear train having a first gear combination and a second gear combination; and wherein the speed control mechanism is moveable between the first gear combination and the second gear combination to control a rotational speed of the dual planetary torque transfer device relative to a rotational speed of the final output.
