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

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.
