There, a wheel 1 shown in broken lines is rotatable on an axle 2. A wheel lever 3 is connected to its axle, which wheel 3 is in turn connected to a vehicle chassis or carriage (not shown) through a coil spring 4. During braking of the vehicle, this suspension system receives a braking force, which produces a rotational torque. The rotation torque is
Along one of the directions of the arrow 5 indicating the rotation direction. It may act on the wheel 1 as a lateral force, causing a vertical movement of the wheel. Therefore, in order to prevent the lateral force, the torque rod 6 is provided between the chassis (or trolley) and the brake flange 7.

And a leaf spring. The leaf spring exerts a spring action on the axle in the first plane,
It is also connected to the axle so as to be radially offset from the axle. Therefore, when acceleration or deceleration occurs in the vehicle, the movement of the axle is suppressed. Also, in this suspension device, one end of a leaf spring is rotatably connected to the vehicle. Thereby, the leaf spring can rotate from the raised position to the lowered position of the wheel.
