Powertrain with a multi-speed transmission

摘要

A powertrain has an engine, torque converter and a multi-speed transmission. The multi-speed transmission has a planetary gear arrangement disposed between an input shaft and an output shaft. The planetary gear arrangement consists of a simple planetary gear set and a compound planetary gear set that are interconnected and controlled by six torque transmitting mechanisms to provide six forward speed ratios and a reverse speed ratio between the input shaft and output shaft. Each of the torque transmitting mechanisms is engaged during at least two of the speed ratios. One of the torque transmitting mechanisms is established during six of the speed ratios including the reverse speed ratio.
