Powertrain with a six speed transmission

摘要

A powertrain has an engine, torque converter and multi-speed transmission. The transmission has a simple planetary gear set and a compound planetary gear set. The gear sets are interconnected between the sun gear member of the simple planetary and the carrier assembly member of the compound planetary. The simple planetary ring gear member is continuously connected with an output shaft and the sun gear member of the compound planetary is continuously connected with an input shaft. Four clutches and two brakes are selectively engaged in pairs to provide six forward speed ratios and one reverse ratio.
