A torque transmission device for a vehicle includes a torque input element coupled to a crankshaft of a combustion engine, a first torque output element coupled to a first input shaft of a gearbox, a rotating electric machine including a stator and a rotor arranged in the direction of the transmission of torque, between the input element and the first output element, a rotor support radially supporting the rotor of the rotating electric machine, the rotor support selectively connected to the input element by an input clutch, a fixed distributor fastened to the gearbox and supporting the rotor support, a fixed wall including a first radial end fastened to the gearbox, and a second radial end connected to the torque input element, a first rolling member arranged between the rotor support and the fixed distributor, and a second rolling member arranged between the rotor support and the fixed wall.

Transmission device for a hybrid vehicle

A torque transmission assembly including a hydrodynamic torque convener able to be coupled to a crankshaft on the one hand, and able to be coupled to a gearbox input shaft on the other, the torque converter including a primary element and a secondary element which are rotationally mobile about an axis of rotation, and damping means including a transmission member and a bearing element, the transmission member including an elastic leaf rotating as one with the primary element or with the secondary element, and the bearing element being home by the secondary element or by the primary element respectively, the elastic leaf being capable of flexing and of transmitting a rotational torque between the primary element and the secondary clement, the flexing of the elastic leaf being accompanied by a relative rotation between the primary and secondary elements.

Torque transmission assembly for a motor vehicle

A vibration damping device for a motor vehicle, features a first movable element () and a second movable element () both rotatable around an axis X, at least one group of elastic members () mounted between the first movable element and the second movable element and acting against rotation of the first movable element and second element with respect to one another, and a phasing member () rotationally movable around the axis X. The first movable element () and the second movable element () are coaxial and capable of transmitting a torque. The phasing member () includes a first portion () and a second portion (), for arranging the elastic members of the at least one group in series so that the elastic members of each group deform in phase with one another.

Vibration damping device

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.

Vibration damping device for motor vehicle transmission drivetrain

A friction clutch device for coupling a first rear motor shaft to a second front forced shaft by allowing free relative axial displacement between the two shafts. The clutch device includes a double shock-absorbing steering wheel having a primary couple input assembly which is fixedly mounted axially to the motor shaft, a secondary couple output assembly which is rotatably connected to a reactive plate of the clutch device which is supported by the forced shaft. An elastic circumferential action member is arranged in a cavity that is peripheral to the primary assembly to rotatably connect the secondary assembly, with circumferential shock absorption, to the primary assembly. The secondary assembly is fixedly mounted axially relative to the reactive plate.

Friction clutch device comprising double damping flywheel having secondary assembly fixedly mounted axially relative to reaction plate

The invention relates to a multiple clutch assembly comprising: first () and second () friction elements; first () and second () plates for applying pressure to said respective friction elements; first () and second () diaphragms for actuating said respective plates, each diaphragm being mobile between a disengaged position (or) and an engaged position (or), said first diaphragm () approaching the second diaphragm () when it passes from the disengaged position thereof to the engaged position thereof; and first () and second () means for actuating said respective diaphragms. Said second actuating means () comprise means for renewing the course of the second diaphragm (), in such a way that the second diaphragm () follows a pre-determined course between the disengaged position (or) and the engaged position () thereof, independently of the degree of wear of the second friction element ().
