Embodiment Construction

[0022] image 3 A piston-cylinder arrangement 9 is shown, such as is used as a clutch slave cylinder in clutch actuating devices of motor vehicles. image 3 A section from a dual clutch slave cylinder inserted in a dual clutch arrangement is shown here. It is also possible for the invention to operate a single clutch in a clutch slave cylinder.

[0023] The piston-cylinder arrangement 9 is formed by a housing 10 which extends rotationally symmetrically around an axis 11 . A ring-shaped pressure chamber 12 extends in housing 10 , in which pressure chamber a piston 13 is movably mounted. The piston 13 here has, facing the pressure chamber 12 , a sealing ring carrier 14 in which a seal 15 is arranged.

[0024] The sealing ring carrier 14 has an approximately U-shaped contour, wherein the base 14 a of the sealing ring carrier 14 rests directly on the piston 13 , while the sides 14 b, 14 c of the sealing ring carrier 14 extend axially along the housing 10 and contact it. body. ...

Abstract

Disclosed is a piston-cylinder arrangement, in particular for a clutch actuation system in a motor vehicle, comprising a housing (10) that is concentrically arranged around a shaft (11), and an annular pressure chamber (1) inside which a piston (13) is movably mounted. A sealing ring support (14) on which a seal (15) is arranged is connected to the piston. In a piston-cylinder arrangement which is less expensive to produce and nevertheless reliably prevents gap extrusion of the seal between the housing and the sealing ring support, the piston is connected without play to the sealing ring support.

Description

technical field [0001] The invention relates to a piston-cylinder arrangement, in particular for a clutch actuation system in a motor vehicle, comprising a housing arranged concentrically around an axis and an annular pressure chamber in which a piston is movably mounted In, the seal ring carrier on which the seal is arranged is connected to the piston. Background technique [0002] Clutch actuating devices are used in motor vehicles in order to break or establish a force flow between the engine and the transmission. In hydraulic clutch slave cylinders, the seal is fastened to the piston with a defined axial play by means of a seal ring carrier or is arranged directly on the piston without play. exist figure 1 A sealed connection with a defined axial gap is shown in . The clutch slave cylinder 1 comprises a housing 2 which is arranged rotationally symmetrically about an axis 3 . The housing 2 here forms an annular pressure chamber 4 in which a piston 5 is movably mounted...
