Claims

[Scope of utility model registration request]

Both air springs on the left side and right side are arranged between the body frame side and the wheel side fixed part on the left side and right side of the car body, respectively, and an air tank that supplies compressed air and each of these air springs are installed. The air springs are connected to each other through left and right connecting passages, and the internal pressure of the air spring is adjusted by opening and closing the connecting passages according to changes in vehicle height to maintain the vehicle height at a substantially constant height. In a vehicle suspension device in which leveling valves to be held are respectively interposed in the left and right connecting passages, air springs on the left side and right side are provided with air springs on the left side and right side for increasing capacity. The auxiliary tanks are connected to each other, and opening/closing valves on the left side and the right side are interposed in the connection paths connecting the air springs on the left side and the right side and each auxiliary tank, and the vehicle The opening and closing operations of both the left side and right side opening/closing valves are controlled in conjunction with the steering operation of the vehicle, and both the left side and right side opening/closing valves are kept open when the vehicle is not being steered. 1. A suspension device for a vehicle, comprising a control unit that switches and operates both the on-off valves on the left side and the right side to an open state during a steering operation of the vehicle.
