1. A clutch mechanism intended to be installed between an engine and a transmission of a motor vehicle, said mechanism comprising:

  • a subassembly comprising;

    at least one clutch (100, 200);

    a clutch support (500) configured to support the clutch radially by means of a rolling bearing (113);

    a clutch control system (300) comprising a housing (307) and at least one annular piston (320, 330) configured to move axially with respect to the housing (307) in order to engage or disengage the clutch (100, 200), the clutch support (500) being arranged in an axially intermediate position between said control system (300) and an output hub (120, 220) of the clutch mechanism;

    a system for axial locking of the control system with respect to the clutch, said axial locking system comprising;

    a first axial locking element (304, 402) configured to implement at least an axial retention between the control system (300) and the transmission (400);

    a second axial locking element (600) configured to implement at least an axial retention between the clutch and a shaft (A1, A2) of the transmission,wherein the clutch mechanism comprises a means (303, 503) for rotational coupling of the clutch support (500) with respect to the control system (300), said rotational coupling means (303, 503) being different from the axial locking system.
