Abstract

The invention discloses a vehicle height adjustment system. The vehicle height adjustment system comprises an oil supply device, a first oil circuit and second oil circuits, and further comprises a control unit and four main control valves, wherein each of the main control valves is connected to the oil supply device through the first oil circuit; each of the main control valves is connected withat least one sub-control valve through the corresponding second oil circuit; the sub-control valves are provided with actuators; the actuators are provided with displacement sensors and pressure sensors; the displacement sensors and the pressure sensors are all connected to the control unit; and the four main control valves and the sub-control valves connected to the main control valves are all connected to the control unit. The vehicle height adjustment system is simple, effective, and ingenious in design. The vehicle height adjustment system can adjust the height of a vehicle body, and adjust the load carried by a hydropneumatic spring after the height adjustment of the vehicle body.

Description

technical field [0001] The invention relates to the technical field of vehicle height adjustment, in particular to a vehicle height adjustment system and a control method thereof. Background technique [0002] The oil-pneumatic suspension is a suspension device that integrates elastic elements and shock absorbers. It overcomes the linear characteristics of leaf springs and can be well applied to engineering vehicles, special vehicles, etc., and has good shock absorption performance, ride comfort and vehicle stability. Driving stability, and can realize the adjustment of vehicle body height. At present, foreign oil-pneumatic springs and oil-pneumatic suspension technologies have become relatively mature products, and their automatic adjustment mechanisms have been applied to various engineering vehicles and special vehicles. However, domestic research in this area started relatively late. [0003] The oil-pneumatic suspension in the vehicle is equipped with an actuator—an o...
