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 a kind of rear airsuspension system of passenger vehicle.
Background technology:
Along with China Coach industry flourish, air suspension more and more applies in the middle of bus industry.The current bracket of domestic passenger vehicle rear-suspension system with the connected mode major part of axle housing is: by being 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 connected mode bracket realizes with connect through upper cover plate, bottom plate and the U-bolt of axle housing, parts are more, and cost is high；It addition, bottom plate is welded and fixed with bracket, owing to welding quality is difficult to ensure that, 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 a kind of rear airsuspension system 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 cancels bottom plate and upper cover plate, simplifies structure, improves the integrated level of passenger vehicle parts.Reducing complete vehicle quality simultaneously, reduce parts usage amount, reduce production cost, it addition, this system uses straight bolt to replace U-bolt, quality reduces, and cost reduces, and after-sales service is convenient.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of rear airsuspension system of passenger vehicle, wherein: include bracket, axle housing, air bag, upper thrust rod and lower thrust rod, the middle part of described bracket is provided with boss, boss is structure as a whole with bracket, axle housing is arranged on boss, and axle housing is connected by straight bolt with bracket, it is provided with propelling rod support in the middle part of described axle housing, upper thrust rod one end is hinged with propelling rod support, the other end is hinged with vehicle frame, being provided with connection seat on described bracket, lower thrust rod one end connects with being connected seat, 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 it may also is that realize: described bracket is c-type bracket.
Technical scheme it may also is that realize: being provided with shock absorber mounting hole on described bracket, amortisseur lower end is connected with the shock absorber mounting hole of bracket, and amortisseur upper end is connected with vehicle frame.
The invention have the benefit that
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 cancels bottom plate and upper cover plate, simplifies structure, improves the integrated level of passenger vehicle parts.Reducing complete vehicle quality simultaneously, reduce parts usage amount, reduce production cost, it addition, this system uses straight bolt to replace U-bolt, quality reduces, and cost reduces, and after-sales service is convenient.
2, simple and reasonable, integrated level is high
Bracket middle-end position used by the present invention increases the boss of integration, it is used for the bottom plate replacing being welded on axle housing, structure is more simplified, the structure of integration also enhances the intensity of bracket, can meet vehicle bridge installation, distance rod is installed, vibroshock is installed, capsule is installed simultaneously, install simple and reliable, it is simple to dismounting.
3, structural strength is high
Present invention eliminates upper cover plate and U-bolt, use straight bolt-connection axle housing and bracket, it is to avoid U-bolt and upper cover plate are combined with gap, structural stability strengthens.Use without bottom plate structure, utilize integrated form bracket support vehicle bridge, it is to avoid the risk that bottom plate ruptures, improve the intensity of structure.
4, control stability is good
The bracket of the present invention uses c-type carrier structure to make the installation site of air spring parallel with trailing wheel, so can effectively spacing around increase air spring, the cornering stiffness of increase car load, effectively improve the control stability of automobile.
5, manufacturing cost reduces, quality reduces
Bottom plate, upper cover plate, these materials of U-bolt have been fallen in optimization of the present invention so that suspension parts cost reduces, and quality lowers.Decreasing the assembling of these materials, assembly technology is simpler, also saves human cost simultaneously, and manufacturing cost reduces again.
6, after-sales service is convenient
The present invention eliminates the use of U-bolt, has used straight bolt instead so that after-sales service is convenient.
