Abstract: A hydrokinetic coupling device is intended, in particular, for a motor vehicle. The hydrokinetic coupling device comprises a casing rotationally connecting a driving shaft and an impeller wheel, a turbine wheel fixed to a turbine hub rotationally connected to a driven shaft, a clutch locking the coupling of the driving and driven shafts, and a damping element comprising elastic washers for restricting the essentially-radial circulation of the fluid at least inside a front axial space which is located between a front guide washer and a web, such that the fluid circulates though the lockup clutch of the device.

Abstract: A hydrokinetic coupling device (10) which is intended in particular for a motor vehicle. The inventive device is characterized in that it consists of a damping element (20) comprising elements (100,110) for restricting the essentially-radial circulation of the fluid at least inside the front axial space (E1) which is located between a front guide washer (28) and a web (29), such that the fluid circulates through the lockup clutch (16) of the device (10).

Abstract: A torsional vibration damping device (1), in particular for a motor vehicle clutch, said device comprising a disc (60) and a support (80) mounted mobile in rotation relative to each other about a common main axis, and linked in rotation via circumferential elastic members (90) damping torsional vibrations, said elastic members being interposed between the disc (60) and the support (80) and maintained in position circumferentially via lugs (65) of the disc (60) and lugs (82,84) of the support (80) whereon are supported the elastic members (90) and radially via a guide ring (100) passing through the elastic members (90) and integral with the disc (60). Said device is characterised in that the lugs (82,84) of the support (80) are mounted on either side of a section of the ring (100) and the lugs (65) of the disc (60) can move freely at the angle between the lugs (82,84) of the support (80).

Abstract: Hydrokinetic coupling apparatus with an axis of rotation X—X, in particular for motor vehicles, in which the connection without clearance between the turbine wheel, the turbine hub and the input element of the damping device is accomplished by axial rivets. Bearings (80) are axially interposed between turbine hub (14) and a hub of a reaction wheel (13).
