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.

An electromagnetic actuating device for a torque transmission system includes a shell arranged around an axis X. The shell being fixed relative to the axis X and includes walls defining an annular cavity which houses a coil and at least partially a plunger which is able to move axially along the axis X to actuate a coupling device.

Electromagnetic actuating device and transmission system provided with said electromagnetic actuating device

A torsional vibration damping device (), in particular for a motor vehicle clutch, said device comprising a disc () and a support () mounted mobile in rotation relative to each other about a common main axis, and linked in rotation via circumferential elastic members () damping torsional vibrations, said elastic members being interposed between the disc () and the support () and maintained in position circumferentially via lugs () of the disc () and lugs () of the support () whereon are supported the elastic members () and radially via a guide ring () passing through the elastic members () and integral with the disc (). Said device is characterised in that the lugs () of the support () are mounted on either side of a section of the ring () and the lugs () of the disc () can move freely at the angle between the lugs () of the support ().

A hydrokinetic coupling apparatus for a motor vehicle including a crankcase (), designed to link in rotation, about an axis X, an input shaft to an impeller wheel; a turbine wheel () designed to be linked in rotation to an output shaft () via hub () and a flange () transversely oriented extending radially outwards relative to the hub; a lockup clutch () coupling the input and output () shafts comprising a piston () for releasably connecting the turbine wheel () to a substantially transverse wall () of the crankcase () against which the piston () is urged to lock the coupling; and at least a friction stop () interposed axially between the turbine wheel () and the piston (). A friction stop () is arranged radially beyond the outer periphery () of the flange ().
