  • 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.

  • Patent number: 8079448
    Abstract: An axle shaft includes an electromechanically or pneumatically actuated disc brake, especially for a useful vehicle. The brake disc and the caliper can be displaced in relation to each other, and the caliper is fixed to the axle shaft on at least two fixing plates extending preferably from the axle shaft in different directions, at at least respectively one fixing point. The axle shaft is characterized by the arrangement, especially the orientation and/or embodiment, of the fixing plates, and the fixing points of the caliper or of an optional brake carrier on the fixing plates, which is selected in such a way that there is either no displacement of the fixing points on the fixing plates or a parallel displacement of the fixing points on both fixing plates perpendicularly to the brake disc.

  • Patent number: 7523999
    Abstract: A brake cylinder for brakes of a motor vehicle, in particular for utility vehicles, comprising a spring loaded brake section and a service brake section is configurable in such a way that a total length is substantially shortened. In the inventive cylinder, the spring loaded brake section and the service brake section are constructed in such a way that they form a single unit. The brake cylinder comprises a pressurized piston for service braking and a spring-loaded piston for parking braking. The two pistons are connected to each other through a shift cylinder and are disconnected by the pressure relief in a second pressure chamber through the shift cylinder in such a way that the piston is displaceable by a spring-loaded spring. In order to release the brake, the piston for service braking is pressurized and reconnected to the piston. The unit is displaced to a release position by the action of a return spring through the pressure relief of the piston.

  • Publication number: 20060238150
    Abstract: A method for controlling an electronically commutated DC motor is provided, the DC motor including at least one particularly permanent magnetic rotor and a wound stator, which is a drive motor for an adjuster device on a pneumatically operated disc brake. The rotor position is determined from electrically measured parameters without sensing of the rotor position. The invention is characterized in that two determination methods for determining the rotor position from electrically measured parameters are combined with each other, whereby one is an inductive measurement and a further one of the determination methods is a measurement of the inducted voltage.

  • Patent number: 6851761
    Abstract: A control process can be carried out during parking braking by way of a parking brake arrangement. The brake is applied by way of a service brake cylinder, and a position of a piston rod is fixed by rotation of a self-locking rotating spindle and application of the rotating spindle to the piston rod or an element connected in front of the piston rod. By additionally rotating the rotating spindle during parking braking, compensation can be made for shrinkages, particularly of a brake disk and/or brake linings, which occur during brake cooling.
