To be significantly larger than spiral spring suspensioning system with frequency, and with air as the thrust power for adjusting chassis height, shock absorber
Sealing also needs to further raising, if air-supported shock absorber or air bag leak air, then whole system just will be in paralysis
Traffic accident occurs for state, more serious meeting.
Patent No. CN201320701472.0 china national practical new-type patent discloses a kind of air suspension, including suspension
Bracket assembly, the shock absorber and connector for playing cushioning effect；Connector sequentially passes through suspension bracket assembly and shock absorber, and makes to hang
Hanging prop seat assembly and shock absorber are detachably connected.Suspension of the structure with is compared, using the side being detachably connected
Formula, installation and transportation are convenient, maintenance changes simple, can save maintenance cost, still, and above-mentioned technical proposal has problems with and lacked
Point：Although the air suspension can make vehicle pass through potted road surface, if vehicle passes through the gradient relatively steep and concavity and convexity
During larger road surface, short time air bag and shock absorber have little time to adjust chassis, air bag and shock absorber is jolted severity, make shock absorber
Leaked air with air bag, and then occur traffic accident.
To sum up, in order to ensure traffic safety and comfort level, it is necessary to designing one kind is adapted to a variety of situation road travelings, it can protect
Protect air bag and shock absorber jolting suddenly in driving and influence the air suspension system of its service life.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of air suspension system, efficiently solves at present
The problem of adaptability that air suspension is present is not strong, security is inadequate, service life is short, its object is to there is provided a kind of air
Suspension arrangement, it is adaptable to the traveling of vehicle on a variety of situation road surfaces, and each part of air suspension can be reduced in the pavement damage that jolts
Probability, improve the service life of each part and the security of driving.
To achieve the above object, the technical scheme that the utility model solves that its technical problem used is：The air hangs
Hang device, including be arranged on the suspension bracket of chassis crossrail lower end, lifting bracket, shock absorber, be oriented to leaf spring, lifting air bag and hold
Weight air bag, it is characterised in that：Described to be oriented to the lower end that leaf spring is arranged at chassis crossrail, the one end for being oriented to leaf spring is fixed on suspension support
In seat, the upper end of suspension bracket is fixed on chassis crossrail lower end, and the lower end of suspension bracket is fixed with lifting bracket, lifting bracket
Lifting air bag is installed, lifting air bag is provided with least two independent gas-bearing formations；It is oriented to the upper end in the middle part of leaf spring and is fixed with leaf spring pressure
Iron, the top of leaf spring foundary weight is connected with U-bolt, and the lower end of U-bolt is fixed with clamp, is oriented to the lower end in the middle part of leaf spring and fixes
There is collet, collet is spliced into cavity structure, cavity structure with clamp and is provided with vehicle bridge, and the lower end of vehicle bridge is wound with steel wire rope,
Steel wire rope is fixed in fixing axle, and fixing axle is fixed on the inner side of chassis crossrail；The other end top of guiding leaf spring, which is fixed with, holds
Weight air bag, load-bearing air sac is provided with least three independent gas-bearing formations.
The fixing axle is set to dumbbell structure.
The fixing axle is provided with two, and the distance between two fixing axles are identical with the width of vehicle bridge.
Blow vent is respectively arranged with the independent gas-bearing formation of the lifting air bag and load-bearing air sac.
In the air suspension system that the utility model is related to, the lower end of vehicle bridge is wound with steel wire rope, and the solid chassis of steel wire rope is horizontal
In fixing axle on the inside of beam；Lifting air bag and load-bearing air sac are all provided with being set to the structure of multiple independent gas-bearing formation compositions, and each gas-bearing formation
On be provided with blow vent.The setting of said structure obtains following beneficial effect：The steel wire rope for being wrapped in vehicle bridge lower end is fixed on bottom
Position-limiting action is played on disk crossbeam, when vehicle passes by the larger road surface of bumpiness, can prevent that car body from jolting suddenly and cause vibration damping
The gas leakage that device, lifting air bag and the unexpected stress of load-bearing air sac are caused；Air bag and load-bearing air sac are lifted at least provided with two independent gas
Layer can avoid causing the possibility of whole air suspension system paralysis due to gas leakage, both reduce potential safety hazard during driving, again
Improve service life of the air suspension on different situations road surface.
