  • Patent number: 8733516
    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.

  • Patent number: 8424655
    Abstract: A brake cylinder for pneumatic vehicle brakes includes a spring brake section for parking brake actions and a service brake section for service brake actions combined in one housing. The housing is subdivided by a piston into two compartments, one compartment being used as the pressure compartment for the service brake, and the brake spring of the spring section being arranged in the other compartment on the opposite end of the piston. The brake spring acts upon an additional spring piston, which can be locked and released relative to the piston by a pneumatic locking mechanism. The spring piston is connected to a piston rod directly or via additional elements to actuate the brake. Once the locking mechanism is released, the brake spring displaces the pistons relative each other during a parking brake action. At least one pneumatic valve for controlling the brake cylinder are integrated into the brake cylinder.

  • Patent number: 8397884
    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.
