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. The point of connection is located in each case between the joint valves (10, 11) and the individual wheel multi-directional control valves (12 to 15).
