ABSTRACT:
A brake system with brake slip control and traction slip control provided for road vehicles comprises a braking pressure generator (1) comprising a single-type or tandem-type master cylinder (2, 9, 9'), a power brake booster (10, 10', 10") connected upstream in the pedal line and a positioning device (11) between the master cylinder and the power brake booster. Multiple-way valves (4, 5, 5', 5", 5"', 34-36, 49-51, 66-68) are provided which, in the event of brake slip control, cause dynamic fluid delivery out of a dynamic circuit, (e.g., a power brake booster (7, 10, 10', 10")) and which, for traction slip control, will interrupt the connection to the dynamic circuit and bring about direct communication with the auxiliary energy source (8, 8'). The pressure introduced for traction slip control will be delivered by way of the secondary-side or pedal-side chambers (3, 39, 40, 53, 54) within the master cylinder (2, 9, 9') into the working chambers (12, 13) and from there to the wheel brakes of the driven wheels (VR, VL).
