Double-diaphragm air compression damper

Abstract

The invention provides a double-diaphragm air compression damper. The double-diaphragm air compression damper comprises a sleeve, an upper diaphragm compressor and a lower diaphragm compressor; a sealing piston is arranged in the sleeve for dividing the sleeve into a first upper oil cavity and a first lower oil cavity, which do not communicate with each other; the sealing piston is connected witha piston rod penetrating through the first lower oil cavity and downwards extending out of the sleeve; a first elastic film is arranged in the upper diaphragm compressor; a second upper oil cavity anda lower air cavity communicating with the first upper oil cavity are above and below the first elastic film; a first adjustable throttling valve plate is arranged at the upper part of the second upper oil cavity; the lower air cavity is provided with a first intake one-way valve and a first exhaust one-way valve; a second elastic film is arranged in the lower diaphragm compressor; an upper air cavity and a second lower oil cavity communicating with the first lower oil cavity are above and below the second elastic film; a second adjustable throttling valve plate is arranged at the lower part of the second lower oil cavity; and the upper air cavity is provided with a second intake one-way valve and a second exhaust one-way valve. The double-diaphragm air compression damper converts the vibration energy to the air compression energy, and achieves energy conservation and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a double-diaphragm air compression shock absorber. Background technique [0002] The suspension system of the car is the main component of the chassis structure of the car, and the shock absorber and the shock absorber spring are the two core components of the suspension system. [0003] With the development of automotive air spring technology, more and more high-end cars use air springs to replace the original steel springs, which have met the needs of ride comfort and body height adjustability. The traditional shock absorber mainly reduces the vibration of the body structure through damping and dissipation. The vibration energy is converted into heat energy through the damping device and diffused directly into the air, which wastes energy and causes a certain degree of pollution to the environment.
