MOTOR-DRIVEN HUB FOR ELECTRICALLY DRIVING AN AXLE OF A HYBRID-DRIVE MOTOR VEHICLE

摘要

The invention relates to a motor-driven hub for electrically driving an axle of a hybrid-drive motor vehicle, said motor-driven hub including a hub (1) that is rotatably mounted, with respect to a hub holder (2), about a hub axis (A), the motor-driven hub including an electric-drive machine (4) including an external stator connected to the hub holder (2) and an internal rotor, the rotational axis (R) of which is spaced apart from the hub axis (A), the motor-driven hub including a reduction means and a coupling/uncoupling means capable of assuming a coupling position, in which the rotation of the electric machine (4) is coupled with the rotation of the hub (1), and an uncoupling position, the coupling/uncoupling means including a mechanism having a dog and sliding gear (9), said sliding gear being coaxial to the hub (1) while being permanently and rotatably secured to the reduction means, the sliding gear (9) comprising front teeth (13) capable of engaging, in the coupling position, with the front teeth (14) secured to the hub (1).
