Figures 1 and 2 are plan views showing the main parts of the four-wheel steering system of the present invention. Figure 1 shows the state in which the rocking gear, which is a displacement member, is in the neutral position, and Figure 2 shows the rocking gear in the case of a failure. Each figure shows a state in which there is excessive oscillation. Further, FIG. 3 is a schematic perspective view showing the overall configuration of an example of a four-wheel steering device to which the present invention is applied. Furthermore,
Figures 4 and 5 are plan views showing the main parts of a conventional four-wheel steering system. Figure 4 shows the state in which the rocking gear is in the neutral position, and Figure 5 shows the rocking gear swinging excessively in the event of a failure. The respective states are shown below. 1... Input shaft, 2... Swing side bevel gear, 3... Pivot, 4... Drive side bevel gear, 5... Through hole, 6... Rod, 7... Universal joint, 8...

四輪操舵装置。 A four-wheel vehicle that uses an electric drive means to displace a displacement member in both directions around a neutral position, and adjusts the direction and amount of steering of the rear wheels based on the direction and amount of displacement of the displacement member. In the steering device, the device is provided on the displacement member across the neutral position and detects that the displacement member has been excessively displaced.
and a controller that moves the displacement member to a neutral position by controlling the electric drive means when either sensor detects that the displacement member has been excessively displaced. A four-wheel steering device featuring:
