Description
Technical field
The utility model relates to a kind of pneumatic spring, is specifically related to a kind of automobile buffer field.
Background technique
At present, air suspension is not the new technology just researched and developed recent years yet, pneumatic spring is arranged between vehicle body and automobilism mechanism, their basic technical scheme is similar, the structure of usual most of pneumatic spring is that a pneumatic spring bellows is fastened between pneumatic spring lid and the piston of travelling mechanism successively, mainly comprises inside and compressed-air actuated pneumatic spring and the variable vibration damper two-part of damping are housed.In practice process, this kind of pneumatic spring often can suffer the problem of internal overload.Under the effect of external force, pneumatic spring bellows is along with coaxial piston rippling.Compared with conventional steel automobile suspension system, air suspension has a lot of advantage, and the most important is exactly that the elasticity coefficient of spring i.e. the soft or hard of spring can regulate as required automatically.Such as, hanging when running at high speed can be hardening, and to improve vehicle body stability, during long-time low speed driving, control unit can be thought through jolting road surface, to hang deliquescing to improve damping travelling comfort.In addition, wheel is subject to the acceleration that ground shock produces also is one of parameter of considering when automatically regulating of pneumatic spring.Such as, when at a high speed crossing curved, the pneumatic spring of outboard wheels and vibration damper will be automatically hardening, and to reduce the inclination of vehicle body, when emergency braking, electronics module also can lean forward to the inertia that the spring of front-wheel and vibration damper hardness strengthen reducing vehicle body.Therefore, the vehicle that pneumatic spring is housed has the higher manipulation limit and comfort level than other automobile.Traditional chassis lifting technology also incorporates wherein by air suspension.When running at high speed, vehicle body height reduces automatically, thus raising grounding performance guarantees that good High-speed running stability reduces windage and oil consumption simultaneously.At a slow speed by jolt road surface time, chassis raises automatically, passes through performance to improve.In addition, AIRMATIC Dual Control can also keep vehicle body level height automatically, and no matter unloaded fully loaded, vehicle body height can be invariable, and like this under any load condition, the spring travel of suspension system all keeps certain, thus shock absorbing characteristics can not be affected substantially.Even if therefore under full load conditions, vehicle body is also easy to control.A leap of this platform technology really.
