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.

Housing-piston assembly for a coupling device and assembly method

A hydrodynamic clutch includes a hydrodynamic circuit formed by at least a pump wheel and a turbine wheel in a clutch housing with a drive-side housing wall extending to the axis of rotation, and a bridging clutch with a piston capable of shifting axially relative to the drive-side housing wall. The turbine wheel is connected to a hub, which is connected for rotation in common to a takeoff, and is axially supported between the hydrodynamic circuit and the clutch housing, and has first and second flow passages which are axially offset from each other. The hub has a drive-side end with an axial bearing area which can be moved into axial contact with an axial bearing, which is either an axial contact surface on the drive-side housing wall or is assigned to the drive-side housing wall.

Hydrodynamic clutch device

A hydrodynamic clutch includes a hydrodynamic circuit formed by at least a pump wheel and a turbine wheel in a clutch housing with a drive-side housing wall extending to the axis of rotation, and a bridging clutch with a piston capable of shifting axially relative to the drive-side housing wall. The turbine wheel is connected to a hub, which is connected for rotation in common to a takeoff, and is axially supported between the hydrodynamic circuit and a flow guide element, which is supported between the hub and the drive-side housing wall, and has first and second flow passages which are axially offset from each other. The flow guide element has a drive-side end with an axial bearing area which can be moved into axial contact with an axial bearing, which is either an axial contact surface on the drive-side housing wall or is assigned to the drive-side housing wall.

A hydrodynamic clutch includes a housing which can be brought into working connection with a drive; a hydrodynamic circuit formed by a pump wheel and a turbine wheel; a torsional vibration damper having a drive side transmission element, a takeoff side transmission element, and at least one energy storage group between the transmission elements; and a bridging clutch including first friction elements connected to the housing and second friction elements connected to the drive side transmission element. A first flow route extends from a first flow passage to the friction elements, and a second flow route extends from the hydrodynamic circuit to a second flow passage. A sealing arrangement cooperates with the drive side transmission element to separate the first flow route from the second flow route.
