摘要： The invention relates to a vehicle hydraulic brake system with electrohydraulic brake boosting by a piston pump. In order to reduce pressure pulsations on an intake side of the multi-piston pump, the brake system embodies a multi-piston pump, for example, as a six-piston pump with stepped pistons that are driven with an alternating phase shift of 30° and 90° in relation to one another. The phase shift of the drive of the stepped pistons is selected so that the intake volume flows have a uniform phase shift, by which the total intake volume flow of the multi-piston pump has a reduced amplitude of the pressure pulsation, which reduces the repercussions on a master cylinder.

摘要： A system which reduces an electric load on an on-board electrical system of a vehicle. The brake system has an anti-lock and traction control system. The latter has a high-pressure pump, with which pressure fluid can be withdrawn from a supply container and fed into a brake line. A charging valve that can be switched out of its shutoff position into its open position by a control unit is disposed in an intake line of the high-pressure pump. The control unit switches the charging valve into its open position at least whenever feeding of pressure fluid into the brake line is demanded. The brake system is especially well-suited to passenger cars, which have a very severely fluctuating rear axle load status.

摘要： A brake system equipped with an anti-lock and traction control system including first shutoff valve and a first inlet valve of a valve assembly for brake pressure modulation are disposed in a first brake line connected with a master brake cylinder and a wheel brake. Toward the wheel brake, a third return line having a first outlet valve of the first valve assembly begins at the first brake line and leads to a first high-pressure pump, which pumps fluid into the first brake line. On the intake side, the pump communicates with the master brake cylinder, through a suction line having a charging valve. For brake pressure modulation in the traction control mode, phases for pressure buildup, pressure holding and pressure reduction can be controlled with the high-pressure pump, the first shutoff valve, the charging valve and the first inlet valve, while the first outlet valve assumes its shutoff position. A first storage chamber connected to the third return line therefore remains free of pressure fluid. The hydraulic multi-circuit brake system can be used in particular in motor vehicles.

摘要： A vehicle brake system having at least two brake pressure lines, via which a master brake cylinder communicates with wheel brake cylinders, at least one valve is incorporated in each brake pressure line to close the brake pressure lines in the event of anti-skid control. Each brake pressure line is also assigned a return pump, which bypasses the valve. At least one valve, in the currentless state or with the absence of pressure buildup in a brake pressure line, blocks this brake pressure line and communicates with a control unit for pulsed opening upon pressure buildup in the brake pressure line. Because of the additional disposition of a pressure valve and check valve in a bypass around the pulsed valve, expensive pressure reducers are dispensed with, with little additional expense in the anti-skid control system. Even if the anti-skid control system fails, stability during braking is assured.

摘要： The invention is based on a dual-circuit anti-lock vehicle brake system (10) with a tandem master cylinder (12), a switchover valve (14) following the latter, a brake pressure modulation valve assembly (18, 20) that has a brake pressure buildup valve (18) and a brake pressure reduction valve (20) for each wheel brake cylinder (16), and a return pump (24). To enable building up brake pressure rapidly for vehicle dynamics control, the invention proposes one additional pump (28) in each brake circuit (I, II), whose intake side is connected directly to the master cylinder (12) and which feeds in the direction of the wheel brake cylinders (16) connected to to this brake circuit (I, II). As a result, a brake pressure buildup is possible in each wheel brake cylinder (16), even when the master cylinder (12) is not actuated, which buildup can be modulated for individual wheels in a manner known per se.
