Multiple speed overdrive transmission for a motor vehicle

摘要

A multiple speed transmission for motor vehicles includes three simple planetary gearsets, and hydraulically actuated friction clutches and brakes for controlling operation of the gearsets and altering the torque delivery path between an input shaft and an output shaft. A friction brake is provided for operation in reverse drive to share the torque reaction with another friction brake. The transmission is suited to produce six or seven forward speed ratios and a reverse drive ratio.
