A release system (1) for a clutch and/or an accelerating coupling (2) in a motor vehicle, which automatically compensates for wear on the clutch and/or accelerating coupling (2). The release system (1) includes of a piston-cylinder unit (24), which is arranged concentrically with a transmission input shaft (12) and features a cylinder (13) and two pistons (14, 17) that delimit two pressure chambers (16, 19). The piston-cylinder unit is controlled both pneumatically and hydraulically. |
