Problems solved by technology

Due to the existence of natural vibration, the existing damping structure is easy to transmit intermediate frequency vibration, and the critical damping ratio is generally only 0.005. Therefore, the vibration isolation ability near the resonance frequency is poor, the volume is large, the installation is difficult, the structure is complex, the cost is high, and the service life is long. short and many other issues

Abstract

The invention discloses an air spring damping structure. The air spring damping structure is characterized in that the air spring damping structure comprises a damper body (1) and an air exhaust structure (9); the damper body (1) is provided with a fixing bolt (3); the fixing bolt (3) is fixedly connected with a base (7) through an air spring (2); the damper body (1) is connected with the air exhaust structure (9) through an air pipeline (8); an air inlet connector (5) is arranged on one side of the air exhaust structure (9) and the air pipeline (8); a height control valve (4) is arranged on the air exhaust structure (9), and the air exhaust structure (9) is fixedly connected with a connection rod (6).

Description

technical field [0001] The invention discloses a shock absorbing structure, in particular to an air spring shock absorbing structure. Background technique [0002] The air spring is filled with compressed air in a sealed container, and uses the compressibility of the gas to achieve its elastic effect. The air spring has ideal non-linear elastic characteristics. After the height adjustment device is installed, the height of the vehicle body does not change with the increase or decrease of the load. Its characteristic curve of the relationship between deformation and load is a set of curves, which can be designed according to needs. When designing, attention should be paid to the amount of deformation of the rubber parts, and sufficient clearance must be reserved between the rubber parts and the surrounding parts. . The air spring can keep the natural vibration frequency unchanged under any load, can bear radial and axial loads at the same time, and can also transmit a certa...
