Description
Technical field
The present invention relates to semitrailer airsuspension system, in particular to a kind of light-duty American structure semitrailer air
Suspension system.
Background technology
Existing domestic common semitrailer uses concatenation type steel leaf spring equalizing type of suspension more than more than 80% suspension, and the suspension is main
It is made up of parts such as leaf spring, strut mount (being commonly called as hanger), connecting rod, U-bolts, shortcoming is semitrailer ride comfort, comfortable
Property is poor, unsprung mass is big, can not adapt to the light-weighted development of semitrailer, and can not take into account comfortableness and the behaviour of vehicle simultaneously
Handing stability.
The content of the invention
In view of the above-mentioned problems, the invention provides a kind of light-duty American structure semitrailer airsuspension system, so as to come from
The shock loading on ground is effectively decayed, and ensures the security of the ride performance of semitrailer, comfortableness and cargo transport
And the service life of vehicle component is improved, part assembly is reduced, cost is reduced, reaches light-weighted purpose.
To achieve these goals, the present invention can be realized using following technical scheme：
Light-duty American structure semitrailer airsuspension system, including：
The left and right trailing arm bracket assembly being fixedly connected with vehicle frame；
Front end is hinged with the left and right trailing arm bracket assembly respectively by the composite bush carried, rear end and Trailer axle
The left and right trailing arm assembly that assembly is fixedly connected；
Front end is hinged with the left and right trailing arm bracket assembly respectively, what rear end was hinged with the left and right trailing arm assembly respectively
Left and right shock absorber；
The left and right air-bag support being fixed on the vehicle frame；
The carrying air bag that upper and lower end is separately fixed between the left and right air-bag support and left and right trailing arm assembly rear end is total
Into.
In a preferred embodiment of the invention, the composite bush carried in the left and right trailing arm assembly passes through respectively
Left and right bearing pin and left and right adjust pad are hinged with the left and right trailing arm bracket assembly.
In a preferred embodiment of the invention, the left and right shock absorber front end passes through left and right front damper pin respectively
Axle is hinged with the left and right trailing arm bracket assembly；The left and right shock absorber rear end respectively by left and right rear shock absorber bearing pin with
The left and right trailing arm assembly is hinged.
In a preferred embodiment of the invention, the rear end of the left and right trailing arm assembly and the Trailer axle assembly
Between also connected respectively by left and right U-bolt with thick hexagonnut.
In a preferred embodiment of the invention, the left and right shock absorber is in relative to vehicle frame and Trailer axle assembly
Heeling condition.
When vehicle is normally exercised, because impulsive force caused by Uneven road passes through wheel, Trailer axle assembly transmission first
Onto left and right trailing arm assembly, now, left and right trailing arm assembly drives left and right air bag assembly and left and right shock absorber and left and right trailing arm
The composite bush that assembly carries rotates, and compresses and stretches left and right air bag assembly and left and right shock absorber, makes the impact from road surface
Power is decayed in certain limit and is delivered to again on vehicle frame, so as to ensure that the integrity of the ride comfort of traveling and goods, Yi Jicheng
The comfortableness of seat.
When whole suspension system is by side force, the side force is born by the way that left and right trailing arm assembly front end is spacing, so as to
The inclination of whole suspension system is effectively prevented, and is effectively protected vehicle frame, and inhibits the harm of trailing arm transverse shift.
As a result of technical scheme as above, the beneficial effects of the present invention are：
1) in suspension systems, because structural member is using punching press, welding fabrication structure, it is possible to reduce part category, mitigate non-
Spring carried mass, relative to European structural gap suspension, 50kg in light weight；
2) caused vibrations when the airsuspension system can effectively absorb vehicle traveling, protection transport article, especially
Suitable for precision instrument and harmful influence haulage vehicle；
3) control system can adjust using height adjusting valve and height control system valve, bodywork height, to adapt to various dresses
The requirement of platform is unloaded, facilitates cargo handling,
4) each axle axle load is evenly distributed, and contact of the tire with road surface is more balanced, can lift vehicle integral stop performance and turn
Stability when curved, the shock loading of tire is reduced, while tyre life is also accordingly extended.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the light-duty American structure semitrailer airsuspension system of the present invention.
Fig. 2 is that the American structural gap suspension system of light semi-trailer of the present invention removes the front view after section components.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Referring to Fig. 1 and Fig. 2, the American structural gap suspension system of light semi-trailer shown in figure is mainly by left and right trailing arm
