ABSTRACT:
A powertrain includes a hydrokinetic torque converter driven from an electric motor that has an idle speed up to about half of its maximum speed. Three planetary gear sets, the first of these having two sets of planetary pinions mounted on a carrier for rotation, are located in the torque transmission path between the coupling and a differential. The transmission and motor are coaxial with the driveshaft of the vehicle. One-way brakes operate to fix elements of the gear sets against rotation to the transmission housing when torque is transmitted from the motor to the differential. Hydraulically actuated clutches and a brake band produce three forward speed ratios and a reverse drive ratio. The brake band and one clutch can be adapted to produce hill braking and regenerative braking during operation in the first two forward speed ratios.
