Actuation device for a transmission system includes an electric motor kinematically connected to a speed reducer and an output shaft of the speed reducer of axis of rotation, the output shaft being arranged to pivot through three adjacent angular sectors, a first angular sector, a second angular sector adjacent to the first angular sector, and a third angular sector adjacent to the second angular sector. An actuation cam is rigidly connected to the output shaft for rotation therewith. A receiving part is axially movable along a main axis perpendicular to the axis of rotation, comprising a receiving recess for receiving the actuation cam formed by two surfaces parallel to each other and perpendicular to the main axis.

Actuation device for a transmission system

A differential drive system for a vehicle includes a differential drive device, a dog clutch device, and an electromagnetic actuator. The axis of rotation of the differential drive device is situated outside of the annular electromagnet of the electromagnetic actuator.

Differential drive system, more particularly for use in a power train of a motor vehicle

A torque transmission device for a vehicle including at least one motor, the torque transmission device including a first clutch, a second clutch and a transmission member. A first transmission mechanism is provided between the first clutch and the transmission member, and a second transmission mechanism is provided between the second clutch and the transmission member. A connection element arranged to permit or interrupt the mutual rotational drive between the first output element of the first clutch and the transmission member, by means of the first transmission mechanism.

Torque transmission device for a motor vehicle

A transmission mechanism includes an input reduction stage having an input member and an output member rotating about axes that are parallel to a reference axis of the mechanism, an output differential, two output half-shafts which are driven by the differential, at least a first plantetary geartrain kinematically connecting the input reduction stage to the output differential. A switchover mechanism switches the first plantetary geartrain between at least a first speed ratio and a second speed ratio. The first plantetary geartrain and the output member of the input reduction stage are coaxial with the reference axis and with one reference half-shaft of the output half-shafts and surround the reference half-shaft, the first plantetary geartrain being positioned, along the reference axis, between the output member of the input reduction stage and the output differential.

Transmission mechanism and associated propulsion unit

An electric drivetrain including an electric machine and at least one output pinion intended to be connected to an axle differential, and at least one speed reduction device including a first gear train and a second gear train intended to drive the output pinion in rotation in a first rotational direction or a second rotational direction.

Electric drivetrain for motor vehicle

A damping device for damping vibrations of a motor vehicle transmission drivetrain. The damping device features a first element and a second element () rotationally movable around a rotation axis X, an elastic damping member having an elastic blade () mounted rotationally integrally with the first element () and a rolling body movable with respect to the second element along a curvilinear trajectory over at least a predetermined angular sector (A). Movement of the rolling body along the curvilinear trajectory with respect to the second element is accompanied by a movement of the rolling body on the elastic blade, causing the elastic blade to flex.
