    摘要: An actuating unit for a hydraulic brake system for automotive vehicles which operates by a precisely defined change-over pressure and with lost travel independent of the speed of actuation. The actuating unit includes a pneumatic brake power booster and a master brake cylinder connected downstream of the pneumatic brake power booster. The master brake cylinder contains a primary piston coupled with an annular piston of larger diameter. The annular piston confines a filling chamber which may be connected to the hydraulic pressure chamber. The annular piston is adapted to uncouple from the primary piston when the pressure acting on the annular piston reaches a predetermined amount. Thus, the displacement of the filling volume by the annular piston does not require an entire stroke of the master brake cylinder.

    摘要: An actuating unit for anti-lock brake systems for automotive vehicles comprised of a vacuum brake power booster and a tandem master brake cylinder, wherein on failure of the primary pressure chamber a force is simulated which is opposed to the actuating force. For this purpose, a compression spring (28) is arranged in the booster housing (10) which is brought into force-transmitting engagement with the input member only after a predetermined distance of travel of the input member has occurred (3, 23).

    摘要: In an anti-lock automotive vehicle brake system comprising a vacuum brake power booster, a considerable reduction of manufacturing and assembling costs is obtained while the system's reliability in operation is simultaneously augmented by the incorporation into this brake system of a second movable wall arranged within the vacuum brake power booster to which a controllable pressure differential may be applied. The wall isolates two pneumatic working chambers and, in the case of slip control, is movable in a direction opposite to the actuating direction of the master brake cylinder by two compensating cylinders which are connected with the master brake cylinder pressure chambers. A hydraulic chamber which is normally in communication with an unpressurized pressure-fluid supply reservoir is sealed from the reservoir by a retention valve during slip control to hydraulically prevent brake petal induced pressure from being applied to the master cylinder.

    摘要: A brake system for automotive vehicles is disclosed comprising a vacuum brake force booster operatively located between a brake pedal and a master brake cylinder. The vacuum brake force booster includes at least two working chambers separated from one another by a membrane plate, one of the working chambers, through a master magnetic valve, being in communication with a vacuum source and the other working chamber being vented through a control valve acutable by the brake pedal to generate a brake force proportional to the brake pedal force. Connected to the master brake cylinder are brake circuits applying pressure to the wheel brake cylinders. Sensors associated with the wheels detect the rotational behavior of the wheels to identify a locking condition. Output signals are applied to a central electronic regulator supplying, in response to the signals, at least one switch-over signal to the master magnetic valve so that the working chamber in communication with the vacuum source may be connected to atmosphere rather than to the vacuum source. Provided in the vacuum brake force booster is an auxiliary membrane plate fixed to a guide sleeve, separating an additional working chamber in permanent communication with the vacuum source from the vented working chamber. Supported on the guide sleeve, through a spring package, is a piston rod receiving the brake pedal force, while the membrane plate, for generating the brake force, is disposed in a manner displaceable away from the guide sleeve.

    摘要: The invention relates to an electrohydraulic brake system for motor vehicles of the ‘brake-by-wire’ type. The brake system comprises among others a travel simulator cooperating with a master brake cylinder and a pressure source consisting of a hydraulic pump and a high-pressure accumulator.In order to allow deceleration of the vehicle with brake pressures higher than the pressure predetermined in the master cylinder due to the muscular power of the operator upon failure of the electrohydraulic components of the brake system, it is proposed by the invention that a valve assembly (13) is arranged in the connection between the wheel brakes (7, 8, 11, 12) of the vehicle and the pressure source (20 and 21, respectively), which can be actuated both hydraulically by the pressure supplied by the master brake cylinder (2) and by an external force.
