Hybrid motor and propulsion unit for motor vehicle, uses epicyclic gear train to couple engine and electric motor to drive wheels, using a gear brake to select which is driving the vehicle

摘要

The unit has a heat engine (1) and an electric motor (3) coupled through epicyclic gears (2) to a transmission (8) driving the wheels (9). The epicyclic gears have the satellite carriers (21) fixed to an output shaft (26) driving the transmission, and the electric motor drives the planetary gears. A brake (5) locks crown wheel (23) to frame (20), coupling electric motor to output shaft.
