Abstract
The invention discloses a suspension system of a vehicle and a design method thereof. The method utilizes a rubber air spring and a height valve assembly to match with each other in order to adjust the position of the height valve assembly and improve driving smoothness of the vehicle. Concretely, the positional changes of the height valve assembly are prompted by air flushing and exhaust of the rubber air spring. The height valve assembly can reversely control air flushing and exhaust of the rubber air spring such that the position of the height valve assembly is within the specified section. The invention is applied to suspension systems of air springs in different kinds of vehicles. Capabilities of absorbing and consuming vibration energy of shock absorbers are obtained so that a vehicle body and a vehicle frame can rapidly attenuate and driving smoothness of the vehicle is improved.
