ABSTRACT:
A hydraulic dual-circuit brake system with diagonal brake circuit distribution, an anti-lock system ABS and traction control ASR for motor vehicles having a four-channel hydraulic unit with control valves and a return pump. To achieve the ASR function, a third, self-aspirating pump element embodied as a high-pressure pump on the return pump is driven jointly with the return pump, and the wheel brake cylinders of the two driven wheels (HR, HL) are additionally connected--bypassing the control valves--to the third pumping element via a magnetic valve assembly. If at least one of the driven wheels (HR, HL) is spinning, the third pumping element is activated. The magnetic valve assembly is switched over, and the control valve for the slipping driven wheel is switched to "pressure holding". The brake pressure generated by the pumping element is thus fed into the wheel brake cylinder of the spinning driven wheel (HR, HL), and the spinning driven wheel (HR,HL) is slowed down.
