Abstract: A parking brake for a body mounted brake cylinder having either a single locking mechanism cooperates with a threaded shaft that is centrally mounted within the brake cylinder or with multiple locking mechanisms that are positioned symmetrically about the centerline of the brake cylinder push rod so that the push or piston rod can still accommodate arcuate motion of the level of the braking system. The locking mechanism may be controlled by a mechanical linkage or through a pneumatic circuit. Activation of the locking mechanisms prevents axial movement of the brake piston. As a result, engagement of the locking mechanism may be used to prevent a release of the brakes after then have been applied to provide an automatic parking brake.

Abstract: A vehicle brake system comprises an electronic control unit (ECU) for controlling a vehicle brake arrangement, and an electric machine operating as a motor and a generator. The ECU controls valves and the electric machine so that, when a brake pedal is actuated, hydraulic fluid is supplied to a wheel brake from a master cylinder to generate a brake pressure. After a corresponding brake pressure is attained, the supply of hydraulic fluid is disabled, wherein the brake pressure effected by the hydraulic fluid is gradually dissipated, and, correspondingly, the electric machine is operated increasingly as a generator. Upon an increase of driver braking demand, hydraulic fluid is additionally supplied from the master cylinder to the wheel brake, and with decreasing vehicle speed, the electric machine is operated decreasingly as a generator, and, correspondingly, hydraulic fluid is supplied to the wheel brake from an intermediate accumulator and/or from the master cylinder.
Abstract: A friction brake device has a brake rotor that rotates around an axis of rotation, brake pads that can rotate around an axis of autorotation parallel to the axis of rotation, support members that support the brake pads respectively, and pressing devices that press the brake pads against the brake rotor respectively. In the friction brake device, when the brake pads are pressed against the brake rotor, the brake pads revolve around the axis of rotation relatively to the brake rotor while being frictionally engaged with lateral faces of the brake rotor respectively. The support members press the brake pads in a direction perpendicular to the axis of rotation, and frictionally engage outer peripheries of the brake pads with a cylindrical face of the brake rotor respectively. The brake pads auto-rotate around the axis of autorotation upon beginning to be pressed, but come to rest when the pressing force increases.
Abstract: A device for generating a force applied to a component includes a force generating element supported on a resilient support device having first and second, or only a second, spring elements in series in a force transmission chain being stressed during force transmission. The first spring element is less stiff than the second. The first spring element is stressed by a first supporting force over a first spring travel. A spring travel exceeding the first spring travel and a force absorption by the first spring element exceeding the first supporting force are prevented by a first mechanical engaging device. The second spring element is formed by a spring module having a second spring stressed by a second mechanical engaging device with a second supporting force permitting the second spring to only be further stressed when exceeding the second supporting force. A travel sensor detects displacement of the force generating element.
