POWER TRANSMISSION DEVICE OF A MOTOR VEHICLE WITH A FREE-WHEEL MECHANISM CONTAINING AN OIL PUMP

摘要

The device has two electrical machines (6, 7) and their respective shafts (8, 9). A mechanical assembly connects a shaft (2) of an engine, the shafts (8, 9), and a shaft (4) of the wheels (5) with each other. The shaft (2) and the shafts (8, 9) are connected to a shaft (55) of a mechanical oil pump through two free wheels mechanisms (12), where the mechanisms have two distinct, identical and independent free wheel apparatus (56, 57). The apparatus (56, 57) have their respective rings driving the driven rings, where the rings turn in the same rotational axis of the shaft (55).
