Motorized hub including coupling and uncoupling means

摘要

A motorized hub for electric powering of an axle of a hybrid drive automotive vehicle, said motorized hub comprising a hub designed to receive a wheel, the hub being mounted rotationally relative to a hub carrier about a hub axis, the motorized hub comprising an electric drive motor, the electric motor comprising an external stator connected to the hub carrier and an internal rotor whose axis of rotation is remote from the hub axis, the motorized hub comprising reduction means acting between the rotor of the electric motor and the hub, the motorized hub comprising coupling/uncoupling means capable of adopting a coupling position in which rotation of the electric motor is coupled to the rotation of the hub and an uncoupling position in which rotation of the electric motor is uncoupled from the rotation of the hub, the motorized hub being characterized in that the coupling/decoupling means are arranged between the reduction means and the hub.

1. A motorized hub for electric powering of an axle of a hybrid drive automotive vehicle, said motorized hub comprising:
a hub configured to receive a wheel, the hub being mounted rotationally relative to a hub carrier about a hub axis, an electric drive motor:
an external stator connected to the hub carrier; andan internal rotor whose axis of rotation is remote from the hub axis; reduction means acting between the rotor of the electric drive motor and the hub, said reduction means comprise a drive pinion configured to be connected to a shaft of the electric drive motor and a toothed ring configured to be connected to the hub; and coupling/uncoupling means comprises a dog clutch and sliding member mechanism, the sliding member mechanism being coaxial with the hub, the coupling/uncoupling means arranged between the reduction means and the hub and configured to adopt a coupling position in which rotation of the electric drive motor is coupled to the rotation of the hub and an uncoupling position in which rotation of the electric drive motor is uncoupled from the rotation of the hub and constantly connected for rotation with the hub, one end of said sliding member mechanism comprising frontal toothing configured to interact, in the coupling position, with complementary toothing cut on a sidewall of the toothed ring.
