Abstract

The brake system includes a first and a second diagonal brake circuit distribution. A first 2/2-way valve is located in a first line between a master cylinder and a wheel brake cylinder of the front axle. On the wheel brake side, a second line, in which a second 2/2-way valve is disposed, branches off from the first line, leading to a wheel brake cylinder of the rear axle. A third line originates between the second multiposition valve and the wheel brake cylinder and has a pump, with which pressure fluid can be fed from the wheel brake cylinders to the master cylinder. Brake force distribution that is dependent on the dynamic axle load shifting, and within limits, individual-wheel brake pressure control if wheel locking threatens, are thus made possible.
