摘要： An electronically controllable brake actuation system for motor vehicles is proposed, with a master cylinder actuated by means of an actuating pedal, said cylinder with brake pressure transducers driven by an electronic control unit, to which wheel brakes of the motor vehicle are directly connected and which are connectable with the master cylinder by means of hydraulic linkages that can be locked by valve devices, with at least one sensor device to recognize the drivers desired deceleration and also with at least one simulator chamber cooperating with the master cylinder. In order to improve the function of a system of this kind, in particular for ASR control processes, it is proposed through this invention that the valve devices be designed as electromagnetic valves driven by the electronic control unit and that the pressure-volume characteristic of the simulator chamber is independent of that of the wheel brakes.

摘要： In a hydraulic braking pressure control system comprising a brake device (B.sub.FL, B.sub.FR, B.sub.RL, B.sub.RR), hydraulic pressure controller (4) for controlling the hydraulic pressure supply source (2) in accordance with the amount of operation of an operating member (1), an auxiliary hydraulic pressure generator (3) including a working piston (16, 17) operatively connected to the operating member to advance in response to operation of the operating member and being slidably received in a housing (14) with a front surface of the working piston facing a hydraulic pressure chamber (18, 19), a hydraulic pressure transmitter (134) comprising a free piston (132) slidably received in a cylinder body (133) and having opposite ends facing an input hydraulic pressure chamber (130) connected to the hydraulic pressure controller and an output hydraulic pressure chamber (131) leading to the brake device, respectively, and an on-off valve (135) interposed between the hydraulic pressure chamber (18, 19) in the auxiliary hydraulic pressure generator (3) and the brake device and adapted to be closed in response to an increase in output hydraulic pressure from the hydraulic pressure controller, there is further included valve-opening device (136) for forcedly opening the on-off valve in response to the movement of the free piston by a predetermined distance or more in a direction to reduce the volume of the output hydraulic pressure chamber. This ensures that when an abnormality such as wear of a pad or a vapor lock is produced on the side of the brake device in a condition in which the hydraulic pressure supply source is normal, a deficiency of hydraulic pressure can be compensated for, and when a leak of fluid is produced, this can be detected promptly.

摘要： A fluid pressure control system which includes an operational reaction force generating device having a piston which includes a front surface facing a pressure chamber and is operatively connected to an operating member so as to reduce a volume of the pressure chamber in response to the operation of the operating member. The fluid pressure control system further includes a fluid pressure control valve capable of adjusting and outputting an output pressure from a fluid pressure supply source capable of outputting a constant fluid pressure in accordance with the operation amount of the operating member and a stroke accumulator connected to the pressure chamber. The stroke accumulator is of a structural arrangement such that the resilient biasing force acting on the accumulator piston by the movement of the back-up piston toward the accumulator piston with the abnormal reduction in fluid pressure in the pilot chamber connected to the fluid pressure supply source is increased more than the fluid pressure acting on the accumulator piston when the fluid pressure in the pilot chamber is normal. Thus, it is possible in the fluid pressure control system of this invention to prevent the amount in which the operating member operates from being increased more than necessary when the output fluid pressure from the fluid pressure supply source is abnormally reduced.

摘要： A brake system having at least one static pressure line having a static pressure generator. The static pressure line has a bilateral driving piston having one end thereof acted on by a brake pressure and the other end acted on by a control pressure, a changeover valve capable of shutting off the fluid flow from the static pressure generator to the wheel brake, a flow control valve for controlling the control pressure of the driving piston, and an electronic control unit for giving a control command to the flow control valve. The driving piston is controlled so as to keep its predetermined neutral position while the manual input is zero, and, in a normal operation phase, so as to move in such a direction as to reduce the capacity of the static pressure line so that a manual control stroke will be shortened in a predetermined relationship with deceleration or with other braking factors closely associated with the deceleration. In an antilock control phase, the driving piston is controlled so as to move in such a direction as to increase the capacity of the static pressure line, after the fluid flow from the static pressure generator to the wheel brake has been shut off by said changeover valve.

摘要： In a hydraulic brake system for feedback-free ABS control for mobile units, motor vehicles, motorcycles and the like, it is proposed that partial hydraulic units be provided in accordance with the number of desired closed and optionally also open brake circuits, and that the actuating piston of each shutoff valve provided in each partial hydraulic unit and interrupting the communication between the master brake cylinder and the associated wheel brake cylinder and simultaneously opening the communication between the wheel brake cylinder and a plunger-piston, with a pressure equalization face, which is acted upon in parallel with the pressure from the master brake cylinder line. As a result, given suitable embodiment and adaptation of the remaining pressure faces of the actuating piston, a pressure equilibrium is obtained in the sense of compensation for the working pressures exerted. It then becomes possible to embody the triggering pressure for the actuating piston in the shutoff valve independently of the pressure in the master brake cylinder, and to derive it for instance from a high-pressure pump, which starts at the onset of ABS control, without further modification.

摘要： In a pressure modulator for an anti-lock vehicle wheel braking system, responsive to a change of volume of a modulation chamber, caused by a flange of a first central piston element cooperating with a piston step of a second piston element. The piston elements are located in a bore step of the pressure modulator housing which has a diameter which is larger than that of the modulation chamber. The two piston elements each have a displaceable piston flange for forming two sides of a control-pressure space, subject to outlet pressure of an auxiliary-pressure source, which causes the piston elements to be forces, counter to a pre-stress of a modulator spring engaging thereon, into a position which corresponds to a minimum volume of the modulation chamber and when subject to a valve-controlled relief of pressure in the control-pressure space, the piston elements assume the position corresponding to a maximum volume of the modulation chamber.

摘要： A vehicle wheel brake system having a service braking section and a wheel lock control (ABS) section is provided. Under certain conditions the wheel lock control section may not be able to generate sufficient pressure to operate the vehicle wheel brakes when the master cylinder output pressure has been isolated from the wheel brakes. When such conditions occur, the displacement piston of the ABS control section moves to open a bypass valve which connects master cylinder output pressure to the vehicle wheel brake even though the ABS system has isolated it from that wheel brake. The opening of the bypass valve effectively returns the vehicle braking system to service braking until the vehicle operator releases the brake system.
