摘要： The invention relates to a hydraulic vehicle braking system (10) with one wheel braking valve (20, 22) upstream of each wheel brake cylinder (16, 18) and one return flow pump (28, 30) in parallel with each wheel braking valve to the suction side of which the wheel brake cylinders (16, 18) are connected. To enable the antilock system, the return flow pumps (28, 30) are started up and the brake fluid pressure in the wheel brake cylinder (20, 22) of a wheel with the tendency to lock is modulated. For the embodiment of a traction control system the invention suggests a changeover valve (32) in one brake line (14) between the master cylinder (12) and the wheel brake cylinder (18) of a driven wheel of the vehicle. By closing the changeover valve (32) and powering up the return flow pumps (28, 30) braking liquid can be drawn from the master cylinder (121) via the wheel braking valve (20) of the non-driven wheel and pumped into the wheel brake cylinder (18) of the driven wheel by which a brake force is generated which prevents skidding of the wheel concerned.

摘要： The operation of the braking system during braking with and without a risk of locking is to be improved. The braking system (1) has a diagonally divided braking circuit. In a first line (11) between a master cylinder (3) and a wheel cylinder (12) on the front axle there is a first 2/2-way valve (13). A second line (14) branches off from the first (11) on the wheel brake side to a wheel cylinder (15) on the rear axle and has a second 2/2-way valve (16) fitted in it. Between the second valve (16) and the wheel cylinder (15) starts a third line (17) with a pump (18) by means of which pressuring agent may be conveyed from the wheel cylinders (12, 15) to the master cylinder (3). Braking force distribution dependent on the dynamic shift in axle loading and limited brake pressure control in individual wheel brakes when there is a risk of locking is thus possible.

摘要： The invention concerns an economical hydraulic vehicle braking system with an anti-lock arrangement, by means of which system wheel-braking pressures in front wheel brakes and rear wheel brakes connected to a diagonal braking circuit of a four-wheeled vehicle can be varied individually in order to prevent or eliminate the risk of the wheels' locking. The anti-lock arrangement comprises one return pump per braking circuit. According to the invention, the anti-lock braking arrangement (15) is equipped with a total of four electrically controllable valves. In each of the braking circuits (I, II) there is a first valve (28, 29) between the brake master cylinder (2) and a front wheel brake (7, 8) and a second valve (30, 31) between the brake master cylinder (2) and the rear wheel brake (11, 12). All the valves take the form of normally open valves which can be closed electrically. The input (49) of each return pump (32, 33) is connected directly to the front wheel brakes (7, 8) and indirectly, by means of throttle devices (35, 36), to the rear wheel brakes (11, 12). Non-return valves (37, 38), which can be opened in the direction of the inputs (49), can be provided in series with the throttle devices (35, 36). The anti-lock braking arrangement (15) is of economical construction and enables rear wheel brake pressures to be higher than front wheel brake pressures when the system is operating in anti-lock braking mode, in order to improve the braking effect, e.g. when travelling on icy roads.

摘要： A particular prior art suspension system suffers from the disadvantage that is is very stiff at high working pressures and, when operating at low pressures, requires the displacement of very large volumes of hydraulic fluid. The suspension system proposed by the invention has a reservoir system (10) which enables a change in working pressure to be produced with relatively small volumes of hydraulic fluid, even when operating at low pressures. The suspension system described is particularly suitable for motor vehicles.

摘要： The invention starts from a vehicle immobilisation system (34) in which a reversing valve (20, 20') for each braking circuit maintains a pressure accumulated in the wheel brake cylinders (16, 16') when a brake pedal (14) is actuated. Its disadvantage is that the pressure may fall because of small leaks or cooling down of the braking fluid, so that the vehicle may again be moved. To avoid this disadvantage, when an illicit use of the vehicle is recognised, pressure is increased in the wheel brake cylinder (16, 16') by means of a hydropump (30, 30') for each braking circuit.

摘要： An external power source for a hydraulic vehicle braking system, actuated by an external force, having electrically controllable first and second valves is to be protected against overload. To eliminate the use of a prior art safety valve to protect the external power source, it is proposed that the first valve (5) be constructed as a seat valve with a valve seat (28) connected via an upstream inlet port (26) to the external power source (3) with a closing member (29) allocated to the valve seat (28) and a closing spring (30) pressing the closing member (29) against the valve seat (28) designed according to the invention as a safety valve spring. The first valve (5) acts economically as a safety valve protecting the external power source (3) and, for braking operations, as a valve for adjusting wheel braking pressures.

摘要： A known hydraulic vehicle brake system (DE 44 45 401 A1) has brake pressure modulation valve systems situated between a dual-circuit main brake cylinder and vehicle wheel brakes. Traction control is ensured by a pump device which is supplied from a reservoir of the main brake cylinder and forces hydraulic fluid into a first pressure chamber between a first piston and a second piston and feeds it to the brake pressure modulation devices connected to said first pressure chamber in order to lead at least a portion of it into the wheel brakes. The pressure in the first pressure chamber displaces the second piston, thereby ensuring that pressure is also applied to the other brake pressure modulation valve devices. The pump device is therefore a high-pressure pump. It is proposed that the pump device should take the form of a low-pressure pump (76), and a first and second return pump (40, 41) should be allocated to the brake pressure modulation valve devices (42, 43, 44, 45); in automatic brake operation, the first pressure chamber (17) should be connected to the first return pump, while the second pressure chamber (18) should be connected on the inlet side to the second return pump. The low-pressure pump (76) generates in automatic brake operation a load pressure for the return pumps (40, 41) significantly lower than a maximum brake pressure, and the return pumps (40, 41) generate the highest predetermined brake pressure and serve in any anti-lock operation to pump hydraulic fluid from the wheel brakes back to the main brake cylinder. Inside the proposed vehicle brake system, the inexpensive low-pressure pump (76) ensures a high level of efficiency of the return pumps (40, 41) in automatic brake operation.
