  • Steering brake system with electrically controlled valves
    Publication number: 20030071517
    Abstract: The present invention relates to a brake system for vehicles in which the brakes in a first operating mode serve for a steering brake operation and in a second operating mode for braking the vehicle when driving on a road. In such brake systems one has to take care that only the brakes of the rear axle can be controlled independently from each other during the steering brake operation. On the other hand one has to ensure that at least the brakes of the rear axle are actuated together when driving on a road and, if necessary, the brakes of the front axle are controlled in parallel. In order to achieve this function, the state of the art includes complicated mechanical valves or sophisticated special arrangements in the master cylinders being used. It is the object of the present invention to simplify the known generic brake systems. For this reason the invention proposes to utilise electrically controlled valves.
