Embodiment Construction

[0024] figure 1 Represents the power transmission system 1 for the rear axle assembly of a hybrid vehicle, including a motor 2 that directly drives a planetary gear set 4 axially arranged at the end, and is housed in a casing 6 of a transmission mechanism 8 . The planetary gear set 4 itself drives a differential on parallel shafts and laterally offset from the motor 2, which distributes the motion to drive the two shafts of the wheels 10 arranged axially on each side of the differential.

[0025] Each wheel axle 10 includes splines 12 on the outer end which engage corresponding splines in the rear axle housing to drive the wheel. In order to simplify the picture, only the axle 10 of a wheel is drawn.

[0026] The actuator 14 is located on the shaft of the electric motor 2 and on the other side of the transmission mechanism 8 relative to this electric motor, conventionally referred to hereinafter as the rear side, allowing to secure the claw coupling between the planetary gear...

Abstract

Motor vehicle drive train comprising an electric machine (2) connected to driven wheels by a movement transmission (8) to form a vehicle drive line, this transmission comprising an engagement means allowing the drive line to be opened so as to disconnect the electric machine (2) from the driven wheels, characterized in that the means of engaging the drive line comprises an electric actuator (14) that has two stable positions in the absence of electrical current, allowing this drive line to be kept in the open or closed position.

Description

technical field [0001] The invention relates to a motor vehicle power train, including an electric machine driving the wheels, and a motor vehicle equipped with such a power train. Background technique [0002] Hybrid vehicles of the type known comprising a power train comprising a heat engine originally configured and realizing the main motive power of the vehicle, and a power train comprising an electric machine driven by two shafts arranged substantially along the axles of the wheels rear wheel. [0003] The transmission line in turn includes a motor, which is driven by a reducer; a differential device, which disperses and transmits the motion to the two wheel axles. The electric motor is generally permanently connected to the drive wheels to allow the vehicle to be towed from the energy stored in the battery packs, or to use the electric motor as a generator to recharge these battery packs. [0004] But on some vehicles, as indicated in particular by document FR-A12931...
