[0002] A vehicle has different control requirements for vehicle body height and tire ground clearance under different driving conditions. For example, when the vehicle is driving at high speed, the vehicle body height is lowered to lower the center of gravity of the chassis, improve the stability of the vehicle driving at high speed, and reduce wind resistance and fuel consumption. When the vehicle is driving at low speed on a rough road, the vehicle body height is raised to reduce the probability of suspension impact limiting and improve the vehicle's driving performance.

[0030] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0031] 1. When the two meshing conveyor gears rotate in the forward direction (i.e., when the double forklifts are raised), the area between the oil inlet and the two conveyor gears in the conveying chamber is in a low-pressure zone due to the separation of the teeth of the two conveyor gears. At this time, hydraulic oil enters the conveying chamber from the oil inlet. The hydraulic oil is carried by the space formed by the conveyor gears and the conveying chamber, and is carried along the inner wall of the conveying chamber to the side where the teeth of the two conveyor gears mesh. On this side, due to the meshing of the teeth, the hydraulic oil between the teeth is squeezed out, forming a high-pressure zone. Then, the hydraulic oil is delivered to the oil reservoir through the oil quantity conveying adjustment component. This process can absorb and buffer vibration energy. When vehicles and other equipment pass over bumpy roads, the springs are compressed, the shock absorber piston moves downward, and hydraulic oil enters the oil reservoir through the valve. This process is like a buffer. For example, when a car encounters a bump while driving, the wheels move upward, the main spring is compressed, and the flow of hydraulic oil can slow down the compression speed of the main spring, preventing the car body from suddenly sinking, thus making the driving experience more comfortable. Secondly, this process can adjust the damping force.

[0032] 2. By matching the threaded hole with the lead screw, when the lead screw rotates, the connecting block moves up and down, which in turn drives several damping springs fixedly connected to the connecting block to move up and down. The damping springs move upward until their upper ends abut against the stop block and then stop. At this time, the damping springs cooperate with the main spring on the shock absorber. This setting makes the way to adjust the damping more diverse and the damping effect better.

[0033] 2. The rotation of the outer sleeve drives the straight groove to rotate, which in turn drives the push rod two to slide within the straight groove, thereby driving the push rod one and the turntable to rotate. Due to the limiting effect of the polygonal groove on the turntable and the inclined groove on the adjusting pipe, several polygonal blocks slide towards or away from the turntable axis when the turntable rotates. This allows the hydraulic oil to be adjusted through the opening size of the turntable and the adjusting pipe. By controlling the flow rate and speed of the hydraulic oil entering the reservoir cylinder, which is determined by the valve characteristics, the damping characteristics of the shock absorber can be changed.
