SOLUTION: Cutoff valves 8fR, fL, rR, rL are provided in piping paths for connecting control valves 7fR, fL, rR, rL to hydraulic actuators 5fR, fL, rR, rL, and communicating valves 9fR, fL, rR, rL are provided in piping paths for connecting body side and truck frame side cylinder chambers 10fR, fL, rR, rL and 11fR, fL, rR, rL of the hydraulic actuators 5fR, fL, rR, rL corresponding to air springs 4 of front side and rear side trucks. In case of detecting a failure by a body inclination failure detector 12, the cutoff valves are closed, and the communicating valves are opened. Both inclining action on the front truck side and rear truck side is therefore made in the same rotating direction, and inner track side wheels on the reverse rotating side can be prevented from coming off by reverse rotation on the front truck side and rear truck side of a body 3.

A method of detecting the reverse tilt fail state will be described with reference to FIG. First, in step 1, it is determined whether or not the vehicle is traveling on a curve. If not traveling on a curve, it is determined in step 2 whether the difference between the front vehicle body inclination angle θf and the rear vehicle body inclination angle θr is a threshold value θ0 or more. To do. When the difference between the front vehicle body inclination angle θf and the rear vehicle body inclination angle θr is equal to or greater than the threshold value θ0, the inclination control command is set to 0 and the shutoff valve 8 is operated.
fR, 8fL, 8rR, 8rL are closed, the communication valve 9fR,
Release 9fL, 9rR, 9rL. When it is determined in step 1 that the vehicle is traveling on a curved line, first, in step 3, it is determined whether or not the front vehicle body inclination angle is a reverse inclination with respect to the normal inclination angle. It is determined whether the vehicle body tilt angle is a reverse tilt with respect to the regular tilt angle. If the determination is not reverse tilt, the tilt control state is normal and the tilt control is continued. If it is determined in step 4 that the vehicle is in reverse tilt, the rearward side is in the reverse tilt state, so the tilt control command is set to 0, and the shutoff valves 8fR and 8f are set.
L, 8rR, 8rL are closed, and communication valves 9fR, 9fL, 9
Release rR and 9rL. If it is determined in step 3 that the vehicle is tilting backward, it is determined in step 5 whether the rearward vehicle body tilt angle is a reverse leaning angle with respect to the regular leaning angle. Set the command to 0,
At the same time, the shutoff valves 8fR, 8fL, 8rR, 8rL are closed and the communication valves 9fR, 9fL, 9rR, 9rL are released. On the other hand, when it is determined that the vehicle is tilted backward in step 5, both the front and rear are tilted backwards, and similarly, the tilt control command is set to 0,
At the same time, the shutoff valves 8fR, 8fL, 8rR, 8rL are closed and the communication valves 9fR, 9fL, 9rR, 9rL are released.

That is, in the normal leaning state, as shown in FIG. 4, the wheel weight on the inner track side of the curve is the wheel load on the outer track side on both the front and rear sides of the vehicle due to the movement of the center of gravity of the vehicle body. Balance smaller than. However, when the front side and the rear side of the vehicle incline in opposite directions for some reason, for example, when the rear side is in the reverse inclined state as shown in FIG. It becomes almost 0, which is dangerous for derailment. Therefore, if the reverse inclination fail state is detected by the determination of the above-described embodiment and the above operation is immediately performed, even if the reverse inclination side is firmly astringent, the opposite side is determined according to the torsional rigidity of the vehicle body 3 as shown in FIG. Since it tilts in the direction of rotation on the reverse tilt side, a rebalanced state is achieved, and it is possible to prevent wheel weight loss on the inner rail side.
