Abstract

A combination traction slip- and brake slip-controlled brake system comprises a brake pressure generator (1) with an auxiliary energy supply system (2) and a pressure compensating reservoir (3) and electromagnetically actuatable valves (4-11) in the pressure fluid supply conduit to the wheel brakes (34-37) and in the return conduit (28, 28', 28") to the pressure compensating reservoir (3). In addition, a valve arrangement (13, 29, 30, 31) is provided and through which pressure from the auxiliary energy supply system (2) can be introduced the pressure fluid return conduit (28, 28', 28") and by way of outlet valves (8, 9) into the wheel brakes (34-37) of the driven vehicle wheels, with the purpose of controlling the traction slip.
