Embodiment Construction

[0020] figure 1 A first embodiment of a piston-cylinder assembly according to the invention is shown, in which the cylinder forms the housing 1 . The housing 1 consists of an outer pressure wall 2 , between which a pressure space 4 extends, and a guide sleeve 3 , in which a piston 5 is arranged axially movable. The piston 5 is connected to the inner ring 6 of a release bearing 7 which, during the movement of the piston 5 , acts on a clutch of the vehicle, not further shown. The release bearing 7 is supported by a preload spring 8 .

[0021] A sensor target 10 is arranged in the recess 9 of the piston 5 such that the sensor target 10 faces the outer pressure wall 2 of the housing 1 . In this case, the size and shape of the cutout 9 are adapted to the size and shape of the sensor target 10 , so that the sensor target 10 inserted into the cutout 9 ends with the piston wall. Accordingly, protrusion of the sensor target 10 is inhibited. On the outside, on the outer pressure wal...

Abstract

The invention relates to a piston-cylinder assembly, in particular for a clutch actuating device of a vehicle, comprising a concentric cylinder designed as a housing (1), on which a piston (5) is axially movably mounted , wherein said piston (5) acts on a release bearing (7) which operates an actuator, wherein a sensor (11) externally fixedly arranged on said housing (1) is connected to In operative connection is a sensor target (10), which is connected to a movable piston (5). In a piston-cylinder assembly, a rocking movement of the sensor target is inhibited in that the sensor target (10) is fixed directly on the piston (5).

Description

technical field [0001] The invention relates to a piston-cylinder assembly, in particular for a clutch actuating device of a vehicle, which comprises a concentric cylinder designed as a housing in which a piston is axially movable, In this case, the piston acts on a release bearing which actuates the actuator, wherein a sensor which is arranged fixedly on the outside on the housing is in operative connection with a sensor target which is connected to the movable piston. Background technique [0002] From EP 1 898 111 A2 a center separator for hydraulic clutch actuation is known, said center separator having a housing arranged therein and a sleeve fastened thereon, said housing having a through-hole, An annular piston, operatively connected to the clutch, is movably guided on said sleeve, on which an inner release bearing ring is fastened. Here, to detect the axial position of the annular piston, a sensor is fastened to a housing equipped with a movably guided magnet, which ...
