In a brake circuit with pressure medium-operated brakes of two axle groups, of which the second axle group is not dynamically balanced in relation to the first axle group, with a load-dependent brake pressure governor preconnected to the brakes, it is proposed to arrange a controllable valve device (for example relay valve, double shutoff valve, load/no-load valve) between the brakes of the first axle group and the brakes of the second axle group and to trigger this device by way of a pressure-limiting valve supplied from the storage pressure or from the uncontrolled brake pressure or from the controlled brake pressure. The load-dependent brake pressure governor is controlled only as a function of the load state of the first axle group. A variation of the brake pressure fed to the brakes of the second axle group compared to the brake pressure fed to the brakes of the first axle group is thereby obtained which is adjusted not only according to the load but also to the dynamic variation of the coefficient of friction of the axles. |
