Abstract
The invention relates to a rear air suspension system used for a passenger car. The rear air suspension system comprises a support, wherein the middle portion of the support is provided with a boss integrated with the support, an axle case is arranged on the boss and connected with the support through a straight bolt, the middle portion of the axle case is provided with a propelling rod support, one end of an upper propelling rod is hinged to the propelling rod support, the other end of the upper propelling rod is hinged to a car frame, the support is provided with a connection base, one end of a lower propelling rod is connected with the connection base, and the other end of the lower propelling rod is connected with the car frame; the lower end of an air bag is connected with the support, and the upper end of the air bag is connected with the bottom surface of the car frame. The rear air suspension system used for the passenger car has no lower supporting board and upper covering board. According to the rear air suspension system, the lower supporting board and the upper covering board are omitted, the structure is simplified, and the integration level of components and parts of the passenger car is increased. Meanwhile, the weight of the whole passenger car is reduced, the number of the components and parts is reduced, and production cost is lowered. In addition, the straight bolt is used for replacing a U-shaped bolt, the weight is reduced, cost is reduced, and after-sale maintaining convenience is achieved.
Description
technical field:
The present invention relates to passenger vehicle parts technical field, be specifically related to the rear airsuspension system of a kind of passenger vehicle.
background technology:
Flourish along with China Coach industry, air suspension more and more applies in the middle of bus industry.Current domestic passenger vehicle by the bracket of rear-suspension system and the connection mode major part of axle housing is: by be welded and fixed bottom plate on bracket, axle housing upper end arranges upper cover plate, then by U-bolt, upper cover plate, axle housing, bottom plate and bracket are connected, this kind of connection mode bracket realized with being connected by upper cover plate, bottom plate and U-bolt of axle housing, parts are more, and cost is high; In addition, bottom plate and bracket are welded and fixed, and because welding quality is difficult to guarantee, easily cause bottom plate weld cracking; U-bolt and upper cover plate are difficult to fit tightly, and U-bolt dismounting difficulty, cause after-sales service inconvenience.
summary of the invention:
In sum, in order to overcome the deficiency of prior art problem, the invention provides the rear airsuspension system of a kind of passenger vehicle, it is to provide a kind of without airsuspension system after the passenger vehicle of bottom plate and upper cover plate.This system is cancelled bottom plate and upper cover plate, simplifies the structure, and has improved the integrated level of passenger vehicle parts.Reduce complete vehicle quality simultaneously, reduce parts use amount, reduce production costs, in addition, this system adopts straight bolt to replace U-bolt, and quality reduces, cost, and after-sales service is convenient.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The rear airsuspension system of a kind of passenger vehicle, wherein: comprise bracket, axle housing, air bag, upper thrust rod and lower thrust rod, the middle part of described bracket is provided with boss, boss and bracket are structure as a whole, axle housing is arranged on boss, and axle housing is connected by straight bolt with bracket, described axle housing middle part is provided with propelling rod support, upper thrust rod one end and propelling rod support are hinged, the other end and vehicle frame are hinged, on described bracket, be provided with Connection Block, lower thrust rod one end is connected with Connection Block, and its other end is connected with vehicle frame; Air bag lower end is connected with bracket, and air bag upper end is connected with vehicle frame bottom surface.
Technical scheme of the present invention can also be achieved in that described bracket is C type bracket.
On bracket described in technical scheme of the present invention can also be achieved in that, be provided with bumper mounting hole, bumper lower end is connected with the bumper mounting hole of bracket, and bumper upper end is connected with vehicle frame.
Beneficial effect of the present invention is:
1, the present invention is to provide a kind of without airsuspension system after the passenger vehicle of bottom plate and upper cover plate.This system is cancelled bottom plate and upper cover plate, simplifies the structure, and has improved the integrated level of passenger vehicle parts.Reduce complete vehicle quality simultaneously, reduce parts use amount, reduce production costs, in addition, this system adopts straight bolt to replace U-bolt, and quality reduces, cost, and after-sales service is convenient.
2, simple and reasonable, integrated level is high
The present invention's bracket middle-end used position increases integrated boss, be used for replacing being welded on the bottom plate on axle housing, structure is simplified more, integrated structure has also strengthened the intensity of bracket, can meet vehicle bridge installation, propelling rod installation, shock absorber installation, capsule installation simultaneously, install simple and reliable, be convenient to dismounting.
3, structural strength is high
The present invention has saved upper cover plate and U-bolt, uses straight Bolt Connection axle housing and bracket, has avoided U-bolt and upper cover plate to be combined with gap, and structural stability strengthens.Employing, without bottom plate structure, utilizes integrated form bracket support vehicle bridge, has avoided the risk of bottom plate fracture, has improved the intensity of structure.
4, road-holding property is good
Bracket of the present invention adopts C type carrier structure to make the installation site of air bellow parallel with trailing wheel, can effectively strengthen like this all around spacing of air bellow, increases the cornering stiffness of car load, effectively improves the road-holding property of automobile.
5, manufacturing cost reduction, quality reduce
The present invention has optimized bottom plate, upper cover plate, these materials of U-bolt, makes suspension parts cost reduction, and quality lowers.Reduced the assembling of these materials, assembly technology is simpler, has also saved human cost simultaneously, and manufacturing cost reduces again.
6, after-sales service is convenient
The present invention has removed the use of U-bolt, has used straight bolt instead, makes after-sales service convenient.
