A housing-piston assembly for a coupling device, especially a wet-running, multi-plate clutch or a bridging clutch of a hydrodynamic coupling device, wherein the piston () is attached to a housing () by means of connecting elements () in such a way that it has a certain freedom of movement, and rivets () are provided as fastening elements between the piston () and the connecting elements () and/or between the connecting elements () and the housing (), and wherein at least one support element () can be positioned in a riveting position between the piston () and the connecting elements () and/or between the connecting elements () and the housing () in such a way that anvil sections () of the support element () lie behind the set heads () of their associated rivets (). A method of assembling a housing-piston assembly is also provided.

A bridging clutch for a clutch apparatus which has a hydrodynamic circuit in a clutch housing. The bridging clutch may have a piston which is arranged on a hub and which is connected to a piston mount, which is mounted on the clutch housing, such that it can be moved axially via axial force stores. The piston mount has cutouts between radial extensions in the circumferential direction for projections which are provided on the piston and which pass through the piston mount. Axial force stores engage behind the piston mount on its side facing away from the piston and are attached to the piston at one connecting end and have lever ends which act on contact surfaces of the piston mount with predetermined prestressing in the direction of the piston.
