る。When the vehicle is on a straight road, as shown in FIG. 1, an upper laminated rubber 4 provided between the air spring 3 and the vehicle body 1 and a lower laminated rubber provided between the air spring 3 and the bogie frame 2. Each of the rubbers 5 stands upright on a horizontal plane. When the vehicle is on a curved road, the vehicle body leans toward the inner track, as shown in FIG. At this time, the upper surface of the air spring 3 is tilt-controlled in a direction orthogonal to the line of action of the resultant force P of the gravity W and the centrifugal force F by the forced vehicle body control. Therefore, the air spring 3
The upper laminated rubber 4 above the upper surface of the vehicle body 1 and the vehicle body 1 are not subjected to the acceleration in the lateral direction of the floor parallel to this surface. Therefore, the lateral vibration of the bogie caused by the irregular track or the like is damped by the lateral cushioning ability of the upper laminated rubber 4, and the riding comfort in the lateral direction is significantly improved. Then, by allowing the lower laminated rubber 5 provided between the air spring 3 and the bogie frame 2 to move the vehicle body 1 in the left-right direction, the centrifugal force generated when passing the curved road allows the vehicle body 1 to move to the outer gauge side. This is made possible by the displacement of the lower laminated rubber 5, and it is possible to prevent the vehicle body from being biased toward the inner rail side and to bring the vehicle body to an appropriate position in the left-right direction.
