Abstract

The invention belongs to the technical field of automotive suspension and relates to an air spring capable of adjusting the height and rigidity independently and control methods thereof.By means of the air spring capable of adjusting the height and rigidity independently and the control methods thereof, the problems that in the prior art, independent and dynamic adjustment of the height of a vehicle body of a passenger vehicle is difficult to achieve, and effective control cannot be conducted are solved.The air spring comprises a double-cavity air spring body, an air supplying and pressure adjusting device and an air spring controller; the double-cavity air spring body is arranged on a damper of an original vehicle in a sleeving mode and connected with the air supplying and pressure adjusting device through a flexible air-pressure pipe; the air supplying and pressure adjusting device is fixedly mounted in a trunk of the vehicle and connected with all sensors in the air supplying and pressure adjusting device and the signal end of an actuator through a bus; the static control method of the air spring capable of adjusting the height and rigidity independently comprises four working modes, including vehicle starting, static variable height control, static variable rigidity control and vehicle loading and unloading; the dynamic control method of the air spring comprises two working modes, including in-traveling variable height control and in-traveling variable rigidity control.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension, and relates to an air spring and a control method thereof. More precisely, the invention relates to an air spring and a control method thereof which can independently adjust suspension height and stiffness. Background technique [0002] In the modern automobile structure, the suspension is an essential system of the vehicle, it is a necessary structure connecting the body and the wheels. Shock absorbers and springs are extremely important components that transmit and generate force in a suspension. Among them, the spring is responsible for alleviating the impact and vibration of the road surface, improving the ride comfort of the vehicle, and the shock absorber is responsible for converting the vibration energy of the vehicle into heat energy for attenuation. Both of them play a vital role in improving the ride comfort of the vehicle. [0003] Compared with the fixed-rigidity steel...
