现有车辆的车体,如图1所示,空气弹簧等弹性元件2设在其重心上方与P点同高处,由支承在摇枕3上的空气弹簧2使车体1产生摆动。假如在具有这种悬挂装置的车体上作用以横向力,则由于其值为加速度和点P与重心G之间长度Lg的乘积的力矩的作用,使车体位移方向的弹簧荷重增加,另一侧的弹簧荷重减少,因此,车体向横向位移一侧发生
As shown in FIG. 1, the vehicle body of the conventional vehicle is provided with an elastic element 2 such as an air spring and the like. The elastic element 2 is disposed at the same height as the P point above its center of gravity and oscillates the vehicle body 1 by an air spring 2 supported by the bolster 3. If a lateral force acts on a vehicle body having such a suspension, the spring load in the direction of displacement of the vehicle body increases due to the moment of the product of the acceleration and the length Lg between the point P and the center of gravity G, and the other The spring load on one side is reduced, and therefore, the vehicle body occurs toward the lateral displacement side
