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 ().

Hydrokinetic coupling apparatus, in particular for motor vehicle

Hydrokinetic coupling apparatus with an axis of rotation X&#x2014;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 () are axially interposed between turbine hub () and a hub of a reaction wheel ().

Hydrokinetic coupling apparatus, in particular for motor vehicles

The invention concerns a hydrokinetic apparatus, in particular for motor vehicle, comprising a casing ( ); a turbine wheel ( ) secured in rotation to a hub ( ); a lock-clutch comprising a piston ( ) whereof the radially inner part ( ) is mounted sliding along an outer cylindrical shaft ( ) belonging to the central ring called piston ( ) whereof a rear end surface ( ) extends opposite a transverse surface belonging to the turbine wheel ( )/hub ( ) assembly, and comprising stop means ( ) axially interposed between the central ring and the turbine wheel/hub assembly. The invention is characterised in that are provided radial centering means for axial stop ( ) relative to the hub ( ) or relative to the piston ( ) or relative to the web ( ).

Hydrokinetic coupling apparatus, in particular for motor vehicle, comprising a needle thrust bearing between the piston and the turbine hub

The invention concerns an apparatus comprising a housing ( ) with a radial wall ( ) coupled with another input shaft, a turbine wheel ( ) coupled with a hub ( ) and an output shaft; and a lockup clutch comprising a piston ( ); an annular friction disc ( ) with global radial orientation, coupled in rotation with the turbine wheel ( )/hub ( ) assembly and bearing on a first surface a first counter-track ( ) co-operating with a first friction track ( ) integral with the piston to define a first annular friction zone (Z ), and which bears on its second surface opposite to the first surface, a second counter-track ( ) co-operating with a second friction track ( ) integral with the radial wall ( ) to define a second annular friction zone (Z ). The invention is characterized in that the first and second friction zones (Z Z ) are radially offset relative to each other.

Hydrokinetic coupling apparatus in particular for motor vehicle

The invention concerns a hydrokinetic coupling apparatus comprising a wall ( ) with globally transverse orientation and a central ring ( ) along which the piston ( ) is mounted sealingly sliding to define a control chamber ( ) with variable volume, and comprising an annular disc ( ) linking in rotation the piston ( ) with the ring ( ), which is axially arranged between the transverse wall and the piston ( ), which is linked to the piston by elastically deformable tabs ( ) and which comprises a central part ( ) extending radially inwards opposite an inner surface ( ) of the transverse wall ( ) against which it is axially pressed and whereto it is fixed. The invention is characterised in that the ring ( ) is axially secured to the central part ( ) of the linking annular disc ( ) relative to which the ring ( ) is radially centered.
