The invention belongs to the technical field of engineering damping, and particularly discloses a vehicle body posture adjusting and rigidity adjusting oil-gas damping system which comprises an oil-gas damper body used for being connected between a wheel and a suspension and a volume adjusting cylinder connected with the oil-gas damper body. The oil-gas damper body comprises an oil-gas cylinder barrel and a piston rod slidably arranged in one end of the oil-gas cylinder barrel, one end of the piston rod extends out of one end of the oil-gas cylinder barrel and is connected with a wheel, the other end of the oil-gas cylinder barrel is connected with a suspension, a first floating piston is arranged in the piston rod, and a main gas cavity is formed in the piston rod and located at one end of the first floating piston. A second floating piston is slidably arranged in the oil-gas cylinder barrel, a supporting gas cavity is formed in the oil-gas cylinder barrel and located at the other end of the second floating piston, damping oil is filled between the first floating piston and the second floating piston, and the volume adjusting cylinder communicates with the supporting gas cavity and is used for adjusting the volume of the supporting gas cavity. The posture of the vehicle body and the rigidity of the suspension can be adjusted according to different road conditions and vehicle speeds.

    本发明属于工程减震技术领域,具体公开了一种车身姿态调整及刚度可调的油气阻尼系统,包括用于连接在车轮和悬架之间的油气阻尼器本体以及与油气阻尼器本体连接的体积调节缸,油气阻尼器本体包括油气缸筒以及滑动设于油气缸筒一端内的活塞杆,活塞杆的一端伸出于油气缸筒的一端外并与车轮连接,油气缸筒的另一端与悬架连接,活塞杆内设有第一浮动活塞,活塞杆内位于第一浮动活塞的一端形成有主气腔,油气缸筒的内滑动设有第二浮动活塞,油气缸筒内位于第二浮动活塞的另一端形成有支撑气腔,第一浮动活塞和第二浮动活塞之间填充有减震油,体积调节缸与支撑气腔连通并用于调整支撑气腔的体积,能够根据不同的路况和车速调整车身姿态和悬架的刚度。
