PUMPLESS BRAKING PRESSURE REGULATING SYSTEM FOR MOTOR VEHICLES

摘要

A pumpless braking pressure regulating system for motor vehicles with rear and front-wheel brakes (HR, HL, VR, VL) connected to a master cylinder (10) via at least one pressure line, with pressure regulating valves (9, 9') associated with the wheel brakes which control the pressure medium link between the master cylinder (10) and the wheel brakes and between the wheel brakes and at least one pressure medium store (7) which accepts the pressure medium coming from the wheel brakes when the pressure regulating valves (9) are open, control and regulating electronics (12) monitoring actuating the pressure regulating valves (9, 9'). If the pressure medium store (7) is partly filled, the control and regulating electronics (12), depending on a signal from a sensor (4) fitted to the pressure medium store (7), set at least a pressure regulating valve (9) associated with the rear-wheel brakes (HL; HR) to a position in which there is a pressure medium link only between a rear-wheel brake (HR; HL) and the pressure medium store (7).
