Abstract
A bridging clutch for a hydrodynamic clutch device includes a housing comprising a cover having a friction surface; a piston which can move axially 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; and a pretensioning element supported axially between the first and second support sections for actuating the piston in a predetermined axial direction. A slide device located between the pretensioning element and the second support section permits sliding movement of the pretensioning element with respect to the second pretensioning element mount.
