Automotive suspension is the total of all force transmission connections between vehicle frame (or monocoque body) and vehicle bridge (or wheel) Claim.The main function of suspension is road surface to be acted on vertical reaction (supporting force) on wheel, longitudinal counter-force (driving force and braking Power) and the torque that is formed of lateral reaction and these counter-forces be transmitted on vehicle frame (or monocoque body), to ensure automobile Normally travel.
Suspension is mainly by elastic element, guider and damping element(Damper)Etc. three parts composition.
Elastic element makes to contact as elasticity between vehicle frame and vehicle bridge, bears and transmit vertical load, mitigates and inhibits uneven Impact caused by road surface;Guider is for transmitting longitudinal force, lateral force and its torque, and ensures wheel relative to vehicle frame Or vehicle body has certain characteristics of motion;Damper limits the vibration of vehicle body and wheel to accelerate the attenuation of vibration.Thus may be used See, above three component part plays buffering, guiding and damping effect respectively, and triple combination plays the role of common power transmission.It is anti- Only when uneven road surface travels or turns to excessive lateral inclination occurs for vehicle body, and partial automobile is also equipped with auxiliary elastic element-horizontal stroke To stabilizer and balancing pole.

Gas spring is to be filled with compressed gas in the container of a sealing, its spring is realized using the compressibility of gas Effect.The rigidity of this spring is variable because when acting on the load increase on spring, quantitative gas in container by Compression, the rigidity increase of air pressure raising, then spring;Conversely, when load decreases, the air pressure in spring declines, and rigidity reduces, therefore It has more satisfactory variation rigidity characteristic.Gas spring has two kinds of air spring and hydro-pneumatic spring.Air spring has bellows again With point of membrane type, hydro-pneumatic spring includes single chamber hydragas spring, double chamber hydragas spring, two-stage pressure type hydro-pneumatic spring.
To improve the flexibility of Vehicle De L'Avant Blinde By Creussot suspension, need to realize hydro-pneumatic spring and two kinds of damping systems of helical spring The flexible exchange of system.Therefore it needs to set the erection support of hydro-pneumatic spring upper pin on the car body.However this can increase spiral bullet The degree of freedom of spring shock mitigation system leads to the movement of helical spring and deformation is uncontrolled or even helical spring can be sent out with damper Raw abrasion.
For deficiencies of the prior art, the present invention is proposed.
