Abstract
The invention concerns a plate clutch device (5) for locking or unlocking an elastic coupling between said turbine wheel (1) and a radial wall (2a) of said case, via a set of helical shock absorber springs (22) with circumferential action held in place in the arc-shaped housings (24) integral with the turbine wheel (1) and opening in axial direction towards the radial wall (2a). The housings (24) are directly arranged in the thickened peripheral part (25) of the turbine wheel (1) made of mouldable material which for example can be overmoulded on a central metal disc (23) for connection with the driven shaft, the opposite radial ends (26) of the housings (24) acting as supports for the corresponding ends of the springs (22).
