摘要： The invention relates to a brake system that can be operated in four modes, i.e. a mode which is independent of the driver's will, an unboosted mode operated by physical strength, a hydraulically boosted mode, and an electronically regulated mode. Said brake system comprises a master cylinder (1), a first piston (2) that is coupled to a brake pedal (3), a second piston (4) actuating the master cylinder (1), and a third piston (5) which can be actuated by the first piston (2). At least one elastic element (6, 7) is provided between the first and the third piston (5) while all three pistons (2, 4, 5) are disposed in a housing (8). The inventive brake system further comprises a hydraulic pressure source (9) and a valve unit (10) for reducing the pressure generated by the pressure source (9) to a pressure value that is fed into an intermediate space (11) by means of which the second piston (4) and the third piston (5) are separated from each other in such a way that the third piston (5) is impinged in the direction extending opposite the direction of impingement of the second piston (4) with the aid of the pressure acting upon the second piston (4). According to the invention, a valve member (13) of the valve unit (10) is embodied such that the two faces thereof are subjected to the effect of the pressure prevailing in the intermediate space (11).

摘要： A vehicle braking system includes: a hydraulic booster (13) which applies output hydraulic pressure of a hydraulic power source (12) to a boosted hydraulic pressure chamber (25) after regulating the output hydraulic pressure as a control piston (90) operates to balance reaction force generated by hydraulic pressure of the boosted hydraulic pressure chamber (25) with brake operating input; and a brake stroke simulator (14) installed between the brake operating member (11) and the control piston (90) in order for a driver to feel operating strokes of the brake operating member (11). The brake stroke simulator (14) has: an input member (166) axially slidably housed in the control piston (90) of a cylindrical shape and linked to the brake operating member (11); and an elastic body (167,167') interposed between the input member (11) and the control piston (90). The elastic body (167,167') is formed into a tubular shape so as to come into resilient contact with an inner circumference of the control piston (90) by expanding its diameter under the action of axial compressive force generatedby forward movement of the input member (166). Consequently, the brake stroke simulator (14) allows large hysteresis width in relationship between brake operating stroke and operating load.

摘要： A brake booster (11, 83) amplifies driver brake pedal input into an output force and travel for operating a master cylinder. A power unit (55, 129) builds and stores high pressure fluid to provide boost. Inlet (59, 133, 139) and outlet (81, 135) solenoid valves regulate pressurized fluid to the amplifying mechanism. In one embodiment, a single boost chamber (21) provides fluid pressure to operate the master cylinder and to provide a brake pressure indicative opposing force to driver input. One travel sensor (29) monitors the position and movement of an input rod and piston (23), and a second travel sensor (31) monitors the position and movement of an output piston (15). An ECU (63, 143) monitors system parameters and controls a motor pump (77), inlet (59, 133) and outlet (81, 135, 139) valves and peripherals. In another embodiment, the opposing force to the brake pedal input is provided by a separate pressure fluid chamber (111) located within and movable with the output piston (87). Boost chamber pressure and, optionally, output piston travel are monitored to provide a braking force indication. An ECU (143) monitors system parameters including input travel (115) and boost chamber pressure (141), and controls the inlet (133, 139) and outlets valves (135) and peripherals.

摘要： A combined master cylinder and dump valve including a body having a body bore, a brake port, a tank port, and a pressure port with each port being hydraulically connected with the body bore, a piston slideable within the body bore and a plunger,
the piston delimiting a part of the body bore to define a master cylinder for pressurising the brake port, the piston further including a piston seal for isolating the pressure port from the tank port,
a plunger bore being hydraulically connected to the piston bore, such that:

in a rest condition the master cylinder is unpressurised and the seal arrangement isolates the first piston hole set from the plunger bore, thereby isolating the pressure port from the tank port, and
in an actuated condition, the plunger acts to slideably move the piston to pressurise the brake port, thereby hydraulically connecting the pressure port to the tank port.

摘要： A method and apparatus for safely braking a vehicle using a brake system under control of a controller (12). The system includes a parallel system of an electronic brake system for applying the brake and a mechanical brake system for controlling the brake. The mechanical system includes at least one restrictor (70) connected to at least one spring-applied, hydraulically-released parking brake (68). The restrictor (70) reduces the flow of brake fluid from the parking brake (68) so that the parking brake (68) is gradually applied to one or more wheels.
