摘要： An anti-blocking braking system for a land vehicle, comprising a pump (42) which actuates a wheel brake (37), whereby said pump removes brake fluid from a brake pressure sensor unit (31) and supplies it to the wheel brake (37). A first valve arrangement (1) in an a non-actuated position (1.1) blocks the connection between the brake pressure sensor unit (31) and an input connection (42e) of said pump (42) and produces a primary fluidic connection (A) when it is in at least one actuated position (1.3). A first electromagnetic valve (50) in a non-actuated position (50.1), produces a connection between an output connector (42a) of said pump (42) and the brake pressure sensor unit (31) and blocks said connection when it is in an actuated (50.2). A second electromagnetic valve (39) in a non-actuated position (39.1) blocks a connection between the wheel brake (37) and the input connection (42e) of the pump (42) and produces said connection when in an actuated position(39.2). A third electromagnetic valve (38) in a non-actuated position produces a connection between the output connection (42a) of the pump (42) and the wheel brake (37) and blocks said connection when it is in an actuated position (38.2). In order to achieve more precise pressure modulation during a pressure maintenance operational phase, the third electromagnetic valve (38) is placed in an actuated position (38.2) during said phase.

摘要： A mechanical actuating device for displacing a piston (24) in the cylinder bore (20) and for compensating brake lining wear comprises a spreading device (34) which operates axially in a direction of brake actuation, and comprises a strut whose length can be adjusted and which is located between said spreading device (34) and piston (24). The strut whose length can be adjusted is formed by a first strut part (52) having a bolt-shaped end which is screwed into a second, essentially sleeve-shaped strut part (54) that rests with a conical flange (68) on the piston (24). A cavity (90) which is to be filled with brake fluid and which is sealed on one side in a liquid-tight manner exists between the bolt-shaped end of the strut part (52) and the sleeve-shaped strut part (54). In order to ensure a faultless filling of said cavity, the sleeve-shaped strut part (54) has a plurality of radial borings (92) which are located in the area of the cavity (90) and which connect the cavity (90) to the outer peripheral surface of the sleeve-shaped strut part (54). In addition, a plurality of axial continuous borings (96) are provided in the conical flange (68) which are arranged.

摘要： A vacuum brake booster (10) has a vacuum chamber (16) and a working chamber (18), which is separated from the vacuum chamber in a pressure-tight manner by a moveable wall (14). A control valve (20) is provided to obtain a pressure difference on the moveable wall (14). Said control valve has a housing (22) which is coupled with the moveable wall (14) in such a way that a force can be transmitted and a first valve seat (40) which is located in the housing and which interacts with a first valve sealing member (42) to control the supply of atmospheric pressure or overpressure to the working chamber (18) in dependence on the displacement of an input member (24) of the brake booster (10), which is coupled with the first valve seat (40). In order to provide emergency brake support (the assistant braking function), the first valve seat (40) is configured on a displaceable valve member (38), this valve member being coupled with the input member (24) in the direction of activation of the brake booster (10) and being constantly exposed to the pressure in the working chamber (18) on its rear surface facing towards the input member (24). After a predetermined displacement of the displaceable valve member (38) in the direction of operation in relation to the control valve housing (22) has been exceeded, said displaceable valve member is exposed to the pressure in the vacuum chamber (16) on at least a part of its front surface opposite said rear surface. The pressure difference which is then exerted on the displaceable valve member (38) maintains it in the position it has reached until the pressure between the front surface and the rear surface of displaceable valve member (38) is compensated.

摘要： A valve arrangement has a first and second fluid connection (7, 9), a valve member (3) prestressed by a spring arrangement (4) in a first position in which the first and second fluid connections (7, 9) are mutually shut off, and an actuating device (17) to bring the valve member (3) into a second position in which the first and second fluid connections (7, 9) are in a primary flow path (A). For saving costs, reducing the complexity of the arrangement and its mounting space, it should be possible to establish a relatively large flow cross-section between the fluid connections, and to reduce the force exerted by the actuating device to a relatively low level. For that purpose, another valve member (11) is prestressed by another spring arrangement (12) in a first position in which the first and second fluid connections (7, 9) are mutually shut off, and the valve member (11) can be brought by another actuating device into a second position in which the first and second fluid connections (7, 9) are in a secondary flow path (B), so that when the valve arrangement (1) is actuated, the first and second fluid connections (7, 9) are at first only in the secondary flow path (B) and then in the primary flow path (A), or in the first and second flow paths (A, B) simultaneously. The flow cross-section of the primary flow path (A) is larger than the flow cross-section of the secondary flow path (B). The disclosed valve arrangement is preferably used in a brake with an antilock system.

摘要： The invention relates to an actuator module for a vehicle brake, comprising a drive connected to the input side of a lever system, where an output side of the lever system is configured for the actuation of at least one friction element of the vehicle brake. When such a vehicle brake is used as a parking brake the friction element is subjected to static prestressing forces. To absorb these forces already within the actuator module the invention provides for the lever system to be transferred from a service brake zone in which it is self-releasing beyond its force inversion point to a parking brake position in which it is self-locking. The invention also relates to various actuating possibilities in such an actuator module and to their use in a vehicle brake.

摘要： The invention relates to a vacuum brake booster (24) with a control valve housing in which an armature (38) is provided that interacts with a permanent magnet (40) and that is rigidly coupled on the one hand with the input member (26) in the direction of actuation and on the other hand with the first valve seat (64). A spring (42) prestresses the armature (38) against the direction of actuation and maintains it in the initial position of the control valve (22) at a first distance from the permanent magnet (40). When approaching the permanent magnet (40), the armature (38), as soon as a predefined second distance that is smaller than the first distance is reached, is pulled by the permanent magnet (40) against the force which the spring (42) exerts on the armature (38), thereby releasing the rigid coupling with the input member (26) in the direction of actuation so that it contacts the permanent magnet (40). In order to dampen any undesired knocking sounds, the spring (42) that prestresses the armature (38) against the direction of actuation is mechanically coupled with the input member in such a manner that it dampens the return movement of the input member (26) that is caused when the armature (38) is released from the permanent magnet (40) before the input member (26) has completed the return movement that is maximally possible relative to the control valve housing (24).

摘要： An electro-hydraulic braking system of the type capable of operating in a braking-by-wire mode wherein hydraulic pressure is applied to braking devices (18a, 18b, 18c, 18d) at the vehicle wheels in proportion to the driver's braking demand as sensed electronically at a brake pedal (10), in a push-though mode wherein hydraulic pressure is applied to the braking devices (18a, 18b, 18c, 18d) at the vehicle wheels by way of a master cylinder (34) coupled mechanically to the brake pedal (10) and in an ABS mode in which the braking pressures at the individual wheels are controlled in dependence, inter ala, on the detected rotational behaviour of the vehicle wheels, and which includes a hydraulic travel simulator (38) which is connected hydraulically to the master cylinder (34) by way of an electrically controlled isolation valve (36) for providing improved feel for the driver through the brake pedal in the push-through operating mode. In order to ensure that the brake pedal cannot be pushed beyond a position corresponding to a wheel-locking pressure, and thereby make it easier for the driver to modulate the brake pressure and avoid excessive deceleration if the road adhesion improves, the travel simulator isolation valve (36) is arranged to be closed when the ABS mode is active.

摘要： An electro-hydraulic braking system of the type which operates normally in a brake-by-wire mode wherein hydraulic pressure is applied to braking devices at the vehicle wheels in proportion to the driver's braking demand as sensed electronically at a brake pedal (10), and which, if the brake-by-wire mode should fail, operates in a push-through mode wherein hydraulic pressure is applied to the braking devices at the vehicle wheels by way of a master cylinder (34) coupled mechanically to the brake pedal (10), the system including also an electric parking braking means for enabling the braking devices to be actuated for parking braking purposes but which is also arranged to be activated to supplement push-through braking in the event of failure of the break-by-wire mode. Electro-hydraulic braking at the rear axle of the vehicle is allowed only when a control unit (13) of the electro-hydraulic braking system has confirmation that the electric parking means is in a satisfactory operational state.

摘要： The invention relates to an electronically controllable brake booster (21) that is controlled by a control valve arrangement which is controlled by an electronic control unit (ECU). The invention is characterized in that the electronic control unit (ECU) determines a command variable (Psoll) using an output signal from a sensor arrangement (11) that detects the wishes of a driver. The invention is also characterized in that the value of the correcting variable (Isoll(n)) remains unchanged for the current passing through the control valve arrangement when compared with a value (Isoll(n-1) issued immediately beforehand when the regulating difference (Xd) determined from the command variable (Psoll) and a regulating variable (Pist) that is correlated with the pressure of a hydraulic cylinder (25) mounted downstream from the brake booster (21) does not deviate from a first predetermined tolerance range (Xs).
