Abstract

The invention relates to a hydraulic actuating piston (24) for a clutch device, comprising an actuating piston (24), a piston chamber (76) which corresponds to the actuating piston, and a supply chamber (78) which is arranged further inward in the radial direction (10) than the piston chamber (76) and via which hydraulic fluid can be fed to the piston chamber (76), wherein the supply chamber (78) is delimited in a first axial direction (4) by a first housing part (20) and in a second axial direction (6) opposite the first axial direction (4) by a second housing part (22), and the first housing part (20) is fastened to a hub (18). The first housing part (20) is fastened to the hub (18) by clamping the second housing part (22) between the first housing part (20) and the hub (18) in the axial direction (4, 6). The invention further relates to a clutch device having such an actuating device (2) and to a method for producing such an actuating device (2).

Description

technical field [0001] The current invention relates to a hydraulically actuated piston for a clutch device having an actuating piston, a piston chamber corresponding to said actuating piston and a A supply chamber capable of supplying hydraulic fluid to the piston chamber, wherein the supply chamber is bounded in a first axial direction by the first housing part and in a second axial direction opposite to the first axial direction by the second The housing part delimits, and the first housing part is fastened to the hub. Furthermore, the invention relates to a clutch arrangement having such an actuating device. The invention also provides a method for manufacturing such a hydraulic actuator. Background technique [0002] Hydraulic actuation devices in clutch arrangements, such as multi-plate clutches, are known in practice. In this case, the known actuating device essentially consists of an actuating piston, a first housing part, a second housing part and a hub, which ca...
