摘要: A master cylinder for use in the power train of a motor vehicle to actuate the brakes or the friction clutch is designed to avoid the generation of screeching noise and/or the transmission of stray movements to the piston rod in response to shifting of the piston relative to the housing and relative to the sealing element(s) between the piston and the housing. This can be accomplished by causing the piston to turn relative to the housing and the sealing element(s) during axial movement in the housing and/or by installing one or more dampers between the piston and the housing and/or between the piston and the piston rod. The dampers can constitute separately produced parts and/or specially configured and/or finished surfaces provided on the piston and contacting the housing and/or the sealing element(s). The invention also relates to improvements in the configuration and/or the material(s) of the piston.

摘要: The friction clutch between the prime mover and the change-speed transmission in the power train of a motor vehicle is actuatable by a slave cylinder cooperating with a master cylinder wherein the piston is movable by a clutch pedal or by an electric actuator. The casing of the slave cylinder is made, at least in part, of a plastic material and defines a plenum chamber arranged to receive pressurized fluid from the master cylinder by way of a conduit extending through a bell which contains the clutch and the slave cylinder. The annular piston of the slave cylinder surrounds the input shaft of the transmission. The plastic material of the casing of the slave cylinder can contain one or more additives which enhance its strength and/or influence its frictional engagement with the adjacent surfaces of the piston or of a lip seal which reciprocates with the piston. The piston and/or the lip seal can be installed in the casing to contact one or two metallic or plastic guide sleeves which are connected to or form part of the casing.

摘要: A sealed, single row angular contact ball bearing is distinguished by the fact that the seal (25, 40, 47, 48, 49, 50) is arranged at both axial ends in the region of the rims (21, 22, 23, 24), one bearing ring (16) having on both sides in each case one receiving opening (37, 44) for the sealing lip carrier (26) and the associated other bearing ring (15) having on both sides in each case one sealing face (30) for the sealing lip (29, 55, 56, 57, 58), and the rims (21, 22, 23, 24) being coordinated with one another in such a way that receiving openings (37, 44) and sealing faces (30) lie in in each case one plane (38, 39) at the same radial spacing from a bearing axis.It is ensured in this way that the same seal can be used for sealing the angular contact ball bearing of generic configuration on both sides.

摘要: A hydraulically controlled disconnect system for a friction clutch of motor vehicles is provided and is constructed as a slave cylinder which includes a pressure housing (2) which is arranged concentrically in relation to a gear box input shaft (3). A guiding sleeve is arranged radially apart from the pressure housing to create a circularly configured pressure chamber (9) in which a ring piston (7) is axially guided and movable. A reinforced seal (8a) on the pressure chamber side of the ring piston (7). The seal (8a) includes sealing lips (14, 15) which are arranged radially spread apart. In accordance with the invention, the reinforcement (18a) of the seal (8a) is held form-locking on the ring piston (7) with a degree of axial and radial freedom.
