摘要： In an hydraulic cylinder for vehicle braking elements, a clamping piston (1) moved in a housing (3) by hydraulic pressure acts relative to a brake lining carrier bearing a brake lining, e.g., in the form of a brake shoe which, during braking, is forced against the brake disk. To prevent the clamping piston (1) in rest position from being pushed back into its housing (3) by axial impact forces, the clamping piston (1) can be coupled at its interior to an hydraulic volume, which, in the neutral position of the clamping piston (1), acts as an hydraulic cushion and counteracts the impact forces. The hydraulic cushion is formed by an auxiliary piston (17) which defines an hydraulic volume at the interior of clamping piston (1) and which, with the clamping piston in rest position, sealingly abuts the clamping piston and locks the hydraulic volume relative to the pressure chamber (11) of the clamping piston (1), but when the clamping piston (1) is pressurized, produces an unobstructed connection between the pressure chamber (11) and the hydraulic volume within the auxiliary piston (17).

摘要： In a brake cylinder (1) for vehicle brake systems a service and a parking brake are provided within a common housing (25). The parking brake (41) acts on a brake actuating member (37) of the brake cylinder (1) against spring force via a parking brake piston (57) which can be loaded preferably by a pressure medium, and can be locked in the parking brake position by a locking mechanism (43) that acts mechanically, i.e., pressure independently, and that is applied automatically subject to spring force when the parking brake is actuated. The locking mechanism (43) is released preferably by loading a locking piston (59) with a pressure medium in such a manner that the parking brake piston can be returned automatically subject to spring force into its release position and is mechanically maintained in this position.

摘要： A working cylinder without piston rod in the form of a band cylinder. The band (3) in the cylinder covers (8) penetrates a receiving chamber (10) for a sealing and a guide member. Each sealing member comprises a strip-like sealing element on both sides of the band, made of elastic material and, on the piston side, in the form of a lip seal. The sealing elements (12, 13) are installed in the receiving chamber (10) with elastic pre-stressing relative to the band (3). Each guide member facing the sealing member has on both sides of the band (3) a rib-like guide element (23, 24), which is also elastically forced against the band (3) by pre-stressing the sealing elements (12, 13). The guide elements (23, 24) terminate in stop faces (28) with clearance (29) in front of the wall (15) of the receiving chamber (10). The result is that the band (3) can be deflected elastically from its desired position only by the amount of the clearance ( 29); subsequently the guide elements (23, 24) brace themselves form-lockingly against the cylinder cover (8) and prevent any further deflection of the band.

摘要： The combined service and spring-loaded brake cylinder has a service brake piston (11) and a tension piston (16) assigned to a storage spring (17). Between the tension piston, a wear stroke readjusting device with non-self-locking threading (44) is arranged. The threaded spindle (29) of the wear stroke adjusting device can be moved axially and held stationary via a conical coupling (40), which is also spring loaded in the closed direction and closes in the direction of the braking force output. There is also an annular piston (22), which can be moved into the release position by means of a second release pressure cycle at the tension piston (16) in order to move the piston. On an end section (25), which projects into free space, the tension piston (16) carries a nut (27) which can be pulled into its release position by screwing.

摘要： The pull- or push rod of a brake linkage, preferably in the form of a brake clamp, features a double spindle (21) whose oppositely directed threaded ends (20) are screwed into nuts (14) which have a self-locking thread and are hinged to brake levers (4). A flat spiral spring (23) continuously loads the double spindle (21) in the direction of rotation for brake clearance adjustment, while a rotary lock keeps the double spindle (21) in place when the brakes are released. Upon achievement of an application stroke or pressure, for the brakes, the rotary lock is released, and by turning the double spindle (21), excessive play of the brakes at the beginning of the braking process is compensated immediately and completely.

摘要： A parking brake control device has a differential area shuttle valve which has an outlet connected to a brake actuator and a larger area of a poppet directed to an inlet connected to a control valve for applying a parking brake pressure and a smaller area of the poppet facing a second inlet connected to a service brake pressure such that in the event of simultaneous application of parking brake and service brake pressures the shuttle valve will be moved to close off the inlet to the service brake pressure while introducing park brake pressure to the brake cylinder.

摘要： The link joint between a brake cylinder (1) and a brake linkage has a bearing lug (4) attached to a brake cylinder part (2,3). For a pivoting connection between the two, an annular turning surface bearing (14,18) is provided for. The bearing lug (4) is pierced by screw bolts (23) with lateral play, which are screwed to the brake cylinder part (2,3) and the head portions (26) of which are supported by disc springs (28) against the contact point (27) on the bearing lug (4). The rotational center or axis of the turning surface bearing (14,18) is located on the brake cylinder axis (10) in the plane of the contact point (27). With a spherical turning surface bearing (14,18) it is possible to achieve, by an adjusting spring (29), rotatability of the bearing lugs (4) only about a straight line through the ball center (15) of the spherical turning surface bearing (14,18), perpendicular to the brake cylinder axis (10) and the longitudinal axis of the adjusting spring (29).
