To improve the steering comfort, the movement speed of the valve element is controlled.
BACKGROUND OF THE INVENTION The invention concerns a method of steering a vehicle, particularly an articulated vehicle, in which a valve element of a main valve is moved so that it releases or closes connections between a supply connection arrangement and a working connection arrangement in dependence of a steering direction and a steering angle.
SUMMARY OF THE INVENTION The invention is based on the task of increasing the comfort in connection with the steering.
BRIEF DESCRIPTION OF THE DRAWING In the following, the invention is described in detail on the basis of the enclosed drawings of a preferred embodiment. The drawings show:
DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a front-end loader or a shovel loader 1, whose front wheels 2 are arranged on a front part 3 and whose rear wheels 4 are arranged on a rear part 5. On the front part a shovel 6 is arranged, whereas in the rear part 5 is arranged a motor, which is not shown in detail. Front and rear parts are connected with each other by way of a joint 7. This joint 7 is situated approximately in the middle of the front-end loader 1. By means of a hydraulic cylinder 8, the front part 3 and the rear part 5 are mutually swingable. Such vehicles are also known as �articulated vehicles�. When a steering movement is required, the front part 3 and the rear part 5 are articulated towards each other.
