Brake system with slip control for automotive vehicles with a driven axle and a non-driven axle

摘要

A brake system with slip control is disclosed including a master cylinder at whose working chambers the wheel brakes are connected via inlet/outlet valve pairs. A pressure compensation reservoir and an auxiliary pressure supply system are connected to the working chambers via a control valve. The inlet valves of the driven wheels and the auxiliary pressure supply system are connected to the working chambers of the master cylinder via multi-directional valves which are open in the rest position and which can be changed over during traction slip control. The inlet valves of the non-driven wheels directly communicate with the working chambers. In the traction slip control phase, the auxiliary pressure is limited to a maximum pressure required by means of a pressure relief valve.
