For conventional oil-pneumatic springs, the damping force of the stretching and compression strokes is generated by the same damping channel. This structure causes the piston to generate enough pressure to produce damping force only on one stroke, while the other stroke can only be generated by the pressure of the air chamber. Create damping force, the generation of damping force is limited

The invention discloses an air suspension strut capable of independently regulating a height, rigidity and damping. The air suspension strut comprises a main cylinder assembly; the main cylinder assembly comprises a main cylinder body; a main cylinder end cover is mounted at the lower end of the main cylinder body; a piston main body in a main body piston is mounted inside the main cylinder body and is in relative sliding fit with the main cylinder body. The air suspension strut is characterized by also comprising a compression energy accumulator assembly, a stretching bottom valve assembly and a peripheral air supply device assembly. The air suspension strut does not require an external energy accumulator; the occupied space is effectively reduced; the integration level is high; the height and the rigidity of a suspension can be independently regulated; independent regulation on damping of two movement travels of the suspension can be completed; moreover, the passage design can guarantee a sufficient pressure to be established so as to generate a damping force; the air suspension strut can be applied to an electric control semi-active suspension; when vehicle trafficability is regulated, sitting comfort of a vehicle can be guaranteed not to be changed.
Description
technical field [0001] The present invention relates to an automobile air suspension strut, more precisely, the present invention relates to a strut for a vehicle suspension system which can independently adjust height stiffness and damping. 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 springs equipped on traditional vehicles, air springs can ...
