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