Embodiment

[0009] Embodiment: the main cylinder is connected with the axle, the main cylinder (1) and the main airbag (2) form the main airbag cylinder, and the auxiliary cylinder (4) and the auxiliary airbag (5) form the auxiliary airbag cylinder.

[0010] The main airbag cylinder, auxiliary airbag cylinder, and damping cylinder (8) slide and work at the same time under the connection of the fixed coupling (3) and the chute (7). When sliding, oil is supplied by the oil box (6). The top of the damping cylinder (8) has an air outlet valve (9) to link to each other with the car body.

[0011] This structure mainly uses the elasticity generated by the compressibility of the gas to complete the elasticity required by the suspension and the instantaneous resistance generated by the airless vacuum to complete the instantaneous resistance required for vibration reduction, isolate the vibration generated by the wheels during driving, and provide a sense of comfort. extremely strong.

Abstract

An air damper for the suspension of car is composed of primary air-bag cylinder, secondary air-bag cylinder and vibration damping cylinder, and is characterized by that they are cooperating to bear the excessive graviational force and impaction and damp the vibration. Its advantages are high effect, low cost and long service life.

Description

technical field [0001] The invention relates to the configuration of automobile suspension, especially a combination of vehicle gas suspension elasticity and vacuum shock absorber. [0002] In the prior art, vehicles mostly adopt the suspension structure of leaf springs and shock absorbers, and the main problems are that the vehicle has high rigidity and poor suspension elasticity. technical background [0003] Chinese utility model 94239631.7 piston type vehicle shock absorber adopts sealed compressed gas workmanship, and is made up of cylinder and piston. Its disadvantages are: poor gas sealing ability, poor single-cylinder work performance, and strong vibration damping performance. Contents of the invention [0004] The present invention has 2 sealed airbag cylinders. The main air cylinder and the main air bag form the main air bag cylinder, and the auxiliary air cylinder and the auxiliary air bag form the auxiliary air bag cylinder, ...
