  • Patent number: 4818038
    Abstract: A brake system for vehicles with electronic anti-lock control and traction slip control is equipped with a dual-circuit braking pressure generator (1) with preferably diagonal brake-circuit allotment. In the control phases, an auxiliary-pressure supply system (5), instead of the braking pressure generator (1), is hydraulically connected to the wheel brakes. Each brake circuit (I, II) contains, in the pressure-fluid conduits from the braking pressure generator to the wheel brakes, one joint multi-directional control valve (10, 11) and, connected in series thereto, individual wheel multi-directional control valves (12 to 15) which are likewise open in their inoperative position. In lieu of the braking pressure generator, the auxiliary-pressure supply system (5)--which generates pressure proportional to the pedal force during anti-lock control, while it generates uncontrolled pressure during traction slip control--is connected to the wheel brakes during the control phases.

  • Patent number: 4793663
    Abstract: Through a valve arrangement for brake systems of automotive vehicles comprising an electronic antilocking and traction slip control including a two-circuit brake pressure generator (3) and an auxiliary pressure supply system (5) generating an auxiliary pressure proportional to the pedal force and, in traction slip control, generating an uncontrollable auxiliary pressure, either the brake pressure generator (1) or the auxiliary pressure supply system is capable of being connected to the wheel brakes (26-29). The non-driven wheel (HR, HL) of the vehicle is connected directly while the drive wheel (VR, VL) of the vehicle is connected, through an additional multi-way valve, to the brake pressure generator (1) and to the auxiliary pressure supply system (12). Moreover, the wheel brakes (27, 29) of the driven wheels (VR, VL), through additional multi-way valves (20, 21) for the traction slip control, can be directly connected to the auxiliary pressure supply system(5).
