Abstract:
1. A bridging clutch for a hydrodynamic clutch device, said bridging clutch comprising: a housing comprising a cover having a friction surface, the housing being rotatable about an axis of rotation; a piston which can move axially with respect to the housing and can fully rotate with respect to the housing, the piston having a friction surface which faces the friction surface of the cover; a first pretensioning element mount fixed to the cover and having a first support section; a second pretensioning element mount fixed to the piston and having a second support section; a pretensioning element supported axially between said first and second support sections for actuating said piston in a predetermined axial direction wherein said friction surface of said piston is urged toward said friction surface of said cover; and a slide device located between said pretensioning element and said second support section for permitting sliding movement of said pretensioning element with respect to said second pretensioning element mount.
