Abstract
A multi-plate clutch for a motor vehicle has a U-shaped spring element fastened to an intermediate plate for holding adjacent pressure plates at a distance from one another. The intermediate plate is reliably held between the pressure plates. Grinding of friction facings arranged between the intermediate plate and the pressure plates is accordingly minimized. The spring element is arranged in an area of an external toothing of the intermediate plate and therefore does not contribute to an increase in the radial dimensions of the multi-plate clutch.
Claims21
A multi-plate clutch for a motor vehicle, comprising:
- a housing having first and second cover plates and a housing ring connecting radial outer ends of said first and second cover plates, said housing being rotatable about an axis of rotation;
- an intermediate plate arranged for rotating about said axis of rotation with said housing;
- first and second friction facings arranged on opposing sides of said intermediate plate and arranged on a hub rotatable about said axis of rotation relative to said intermediate plate;
- first and second pressure plates arranged in said housing on opposing sides of said intermediate plate for rotation with said intermediate plate and said housing about said axis of rotation and axially movable along said axis of rotation relative to said intermediate plate for pretensioning said first and second friction facings toward the intermediate plate;
- and
- a spring element arranged for separating said first and second pressure plates and said intermediate plate from said first and second friction facings, wherein said spring element contacts each of said intermediate plate and said first and second pressure plates, and wherein at least one of said first and second pressure plates comprises cooling lugs penetrating an opening in one of said first and second cover plates of said housing.
