Abstract: A propulsion system for an electric vehicle includes an assembly of four electric propulsion machines each having a stator and a rotor having an output shaft that is movable in rotation about an axis. Also includes is a common gearwheel that is kinematically connected to the n output shafts and that is able to receive the torque provided by the electric machines so as to form a first speed reducer, and primary gearwheels able to be driven by the common gearwheel. An intermediate shaft is able to be driven by intermediate gearwheels, each primary gearwheel being kinematically connected to a corresponding intermediate gearwheel so as to form a pair of gears with which a second speed reducer is associated, and a secondary shaft that is able to drive the vehicle and that has a secondary gearwheel kinematically connected to the intermediate shaft so as to form a third speed reducer.

Abstract: A motor vehicle transmission system includes a reduction device having at least an output shaft including a first gearwheel and a second gearwheel. A differential drive device is configured to distribute the torque from the reduction device to two half-shafts. The differential drive device includes a coupling device which, in a coupled position, transmits torque between a first element and a second element of the differential drive device, the coupling device further including an actuator. A radial plane, orthogonal to the axes X and W, passes through the first gearwheel and through the coupling device.

Abstract: A module for a system for driving and synchronizing a countershaft of a transmission gearbox. The module includes a coupling device having an input element intended to be rotationally coupled to a reversible electric machine and an output element intended to be rotationally coupled to the countershaft. The coupling device has a coupled state in which the clutch device is able to transmit torque between the input element and the output element and an uncoupled state in which the input element and the output element are uncoupled. Also included is a lock-up device which has a lock-up state in which said lock-up device blocks the rotation of the input element of the clutch device, and a released state in which said lock-up device allows the input element to rotate.

Abstract: A pendulum damping device incorporated into a drive train of a motor vehicle, notably into a clutch, includes a support capable of rotational movement about an axis of rotation, a pendulum assembly of which the movement with respect to the support is guided by at least one rolling member, and an end-stop damping system borne directly by the pendulum assembly and able at least to damp the coming of said pendulum assembly into a position of abutment against the support of said pendulum assembly during the radial fall and/or saturation of this said pendulum assembly. The pendulum assembly also includes at least one radial protuberance designed to pass at least partially through an opening made in the end-stop damping system.
