  • Patent number: 9670970
    Abstract: A transport lock for a clutch release system, in particular for a slave cylinder of a motor vehicle, is provided having an axially movable piston and a clutch release bearing that is connected to the piston being arranged concentrically on a housing. In order to lock the piston or the clutch release bearing during transport, a retaining ring which has a collar that extends outwards in a radial direction and which is secured on the housing in an inner cavity of the clutch release bearing is provided. A contact surface of the piston lies against the collar of the retaining ring in such a way that the retaining ring restricts the axial movement of the piston.

  • Patent number: 9476463
    Abstract: A piston-cylinder arrangement, in particular for a clutch actuation system in a motor vehicle, including 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.

  • Patent number: 8905215
    Abstract: A clutch arrangement for connecting two components, which can rotate relative to one another, of a motor vehicle drive train, in particular for connecting two shafts of a transmission or a shaft to an idler gear rotatably mounted on the shaft. The clutch arrangement has a clutch and an actuator arrangement. The clutch is opened in a first actuator position of an actuator section of the actuator arrangement. The clutch arrangement has a locking device for locking the actuator section in a locked position to keep the clutch closed. The locking device has a slotted-link guide with a first guide section and a second guide section for the actuator section, wherein the locked position can be reached from the first actuator position via the first guide section, and wherein the first actuator position can be reached from the locked position via the second guide section.

  • Patent number: 8584825
    Abstract: This bearing forms a clutching-declutching thrust bearing for a motor vehicle and comprises an inner ring, an outer ring and rolling elements. A flange mounted on the inner ring is equipped with two crenellated series of flange segments extending radially on the same side of a cylindrical web of the flange, and being offset angularly about an axis of symmetry of the inner ring, and axially along said axis. In addition to the bearing, the device further includes a control device, provided with a stationary portion and with a moving portion mounted to move axially and suitable for moving the bearing relative to the clutch mechanism, and a protective bellows disposed between the stationary portion and the bearing. The flange segments define between them an annular volume for receiving and for clamping one edge of the bellows.

  • Patent number: 8474586
    Abstract: A dual clutch actuation assembly includes a housing, an annular central piston, a plurality of satellite pistons, and an annular apply member. The housing includes an inner cylindrical wall, an outer cylindrical wall, and a plurality of satellite cylindrical walls. The inner and outer walls define an inner piston annulus and the satellite walls define a plurality of satellite piston bores. Each of the satellite walls is disposed at least partially radially outward of the outer wall. The central piston is disposed in the inner piston annulus and is in sliding engagement with the inner and outer walls of the housing. The satellite pistons are disposed in the satellite piston bores and are in sliding engagement with the satellite walls of the housing. The apply member is axially engaged with each of the satellite pistons and includes an annular plate portion disposed radially outward of the outer cylindrical wall of the housing.
