Abstract
A brake-slip-controlled brake system for automotive vehicles comprises a master cylinder (1) acted upon by the pedal force (F) in a direct or auxiliary-force-assisted manner and connected with the wheel brake cylinders in the vehicle wheels (VR, HR) e.g. via diagonally allocated hydraulic brake circuits 4, 5. The axial displacement of a rotating cam (32) is controlled by means of sensors (41-43) measuring the braking pressure, the axle loads, and the translational acceleration of the vehicle and feeding corresponding electric signals into an electric circuit arrangement (44). The cam (32) has bevelled control surfaces (48) and acts on braking pressure control valves (8, 9) by way of tappets. In case of control, a pulsating braking pressure is generated by means of said valves (8, 9) the amplitude and the course of the periodic braking pressure variations depending on the axial position and on the design of the cam (32) and hence on the vehicle's braking behavior which was measured by the sensors (41-43) and which was evaluated.
