  • Patent number: 7987953
    Abstract: A brake cylinder for pneumatically actuated vehicle brakes includes a parking brake spring-loaded brake section and a service brake section combined to form a structural unit in a housing. The housing is divided into two chambers by a piston. A cylinder spring of the spring-loaded brake section acts on another spring-loaded piston in the chamber, which can be blocked in relation to the first piston by a pneumatically actuated locking mechanism, and can be released from the first piston by the releasing action of the blocking mechanism. Following the release, the cylinder spring acts between the two pistons and moves the two pistons in relation to each other during a parking brake process. The pneumatically actuatable blocking mechanism acts only in an expansion direction of the spring.

  • Patent number: 7926626
    Abstract: An adjusting device for adjusting the wear of the friction surface on the brake lining and brake disc of a pneumatic disc brake having a clamping device that is actuated by a rotary lever is provided. The device preferably can be inserted into a rotary spindle of the disc brake. An anti-friction body is positioned on both axial sides of a drive element, with the one bodies being a ramp coupling with a freewheeling function. The ramp coupling has coupling bushes and clamping balls, and the coupling bush on the driven side being supported on a spring sleeve. A conical seat is configured between the coupling bush and the sprung sleeve cooperates with the ramp coupling to preclude locking of the coupling bushes.

  • Patent number: 7798294
    Abstract: A lining for a disc brake, in particular, a pneumatically actuated disc brake designed for utility vehicles, includes a pressure plate and a lining material mounted on the pressure plate. At least one return mechanism located on the pressure plate causes axial return of the brake lining after brake applications, and presses against the lining housing of a disk brake and performs a tilting motion in the lining housing when the brake is applied. The return device also includes a tensioning device acting in a tangential direction and including a tensioning spring which, when the brake is not applied, elastically prestresses the pressure plate in the tangential direction relative to a disc of the disc brake that is towards the lining house such that the return device presses tangentially in prestressed manner against the lining housing.

  • Publication number: 20100084229
    Abstract: A brake cylinder for pneumatically actuated vehicle brakes, especially for commercial vehicles, includes a housing. The housing is divided into two chambers by a piston, one of the chambers being used as a pressure chamber for actuating an operating brake section, and a cylinder spring of a spring-loaded brake section being arranged in the other chamber on the opposite side of the piston. The cylinder spring acts on another spring-loaded piston in the chamber, which can be blocked in relation to the first piston by a pneumatically actuated locking mechanism. The other spring-loaded piston is released from the first piston by a releasing action of the blocking mechanism, and is connected to a piston rod for actuating the vehicle brake. Following release of the blocking mechanism, the cylinder spring acts between the two pistons and moves them in relation to each other during a parking braking operation.

  • Publication number: 20100078272
    Abstract: A brake cylinder for a pneumatic vehicle brake, particularly for a commercial vehicle includes a spring-loaded brake section for performing parking brake operations by a spring-loaded spring, and a service brake section for performing compressed air-actuated service brake operations. The spring-loaded brake section and the service brake section are combined in a structural unit in a housing. The housing is divided by a piston into a pressure chamber to which compressed air can be applied and a further space. The pressure chamber serves the actuation of the service brake section in the pressure space and the spring-loaded spring of the spring-loaded section being disposed in the additional space on the opposite side of the piston. The spring-loaded spring acts on an additional spring-loaded piston in the space. The piston is lockable in relation to the piston by a pneumatically operable locking mechanism and releasable from the same by releasing the locking mechanism.
