。[Claims for Utility Model Registration] An air spring whose spring constant can be changed by air pressure adjustment instead of a coil spring, and which can also adjust the vehicle height, and a leveling system that performs air supply and exhaust control for this air spring according to changes in vehicle height. In a vehicle suspension system equipped with an air suspension device having a valve and a shock absorber, the air suspension device has a connection path between the air spring and the leveling valve that supplies and discharges air from an air tank and controls the neutral state. The above-mentioned shock absorber is configured so that the spring constant of the air spring can be adjusted separately from the supply/exhaust control by the above-mentioned leveling valve by connecting electromagnetic valves for setting the respective positions. The solenoid valve and the actuator of the adjustable shock absorber are respectively connected to the output part, and the input part is connected to an adjustable shock absorber that can change the flow resistance of flowing oil. a vehicle speed sensor, a steering angular velocity sensor, a lateral G sensor, and an accelerator OFF switch to detect nose dive and nose up;
A control unit is provided in which a stop lamp switch, a back clamp switch, a vertical G sensor and a vehicle height sensor for detecting pitching and bouncing, and a selection switch for automatically adjusting the vehicle body posture are connected, respectively. The control unit is equipped with control maps for rolling correction, nose dive and nose up correction, pitching and bouncing correction, and when the automatic adjustment mode is selected by the selection switch, it adjusts the direction forward, backward, left and right according to the input information from each sensor. A vehicle suspension system characterized by setting a spring constant of an air suspension device and a damping force of an adjustable shock absorber for each wheel.
