ABSTRACT:
A steering gear with steering drop arm, steering tie rod and steering gear connecting tie rod for a vehicle, which is drivable on wheels on the road and terrain, with a steering mechanism which is actuated selectively hydraulically supported mechanically or purely hydraulically by means of hydraulic cylinders and electromagnetic valves, whereby changing from the hydraulically supported system to the purely hydraulically operating system is by means of a selective connection of a universal shaft, which is connected with the steering wheel, with one of the two systems which serve the actuation of the steering mechanism. A hydraulic pump, driven by a drive motor, and acting on both systems, is connected with a first control valve via a line, a flow control- and pressure limit- valve and a line. On the one hand a line leads from the first control valve to a steering transmission, the latter being actuated by the steering gear by means of universal shaft. Lines lead from the steering transmission to a second control valve. The latter is connected with the hydraulic cylinders of the front axle. On the other hand a line leads from the first control valve to a steering valve which is actuated by means of the steering gear and the universal shaft. Pressurized oil either via a line to a third control valve and via a line therefrom flows to the hydraulic cylinders of the front axle, or via a line to a fourth control valve and via a line therefrom, the third control valve and a line flows to the hydraulic cylinders. Or pressurized oil either the line to the third control valve and via the line therefrom to the hydraulic cylinders of the front axle as well as via a line to the third control valve and via a line therefrom, the fourth control valve and a line flows to the hydraulic cylinders of the rear axle, or the pressurized oil via the line to the fourth control valve and via a line to the hydraulic cylinders of the rear axle as well as via a line to the fourth control valve and via a line, the third control valve and a line flows to the hydraulic cylinders of the front axle.
