Abstract
A steering system for tracked vehicles having two brake circuits which is activated after a failure of the primary steering mechanism. The steering system includes a steering switch (L) that can be controlled by a steering axle which, in the event of primary steering system failure, acts upon the brakes of the vehicle in such a manner that rotation of the steering axle results in a braking action upon a track on the inside of a curve.
