This commercial passenger train rear suspension system includes: the bridge comprises a bridge body, a shock absorber, an air bag assembly, an upper thrust rod and a lower thrust rod, wherein the shock absorber support and the air bag support are welded on the bridge body, the shock absorber and the air bag assembly are respectively fixed on the corresponding supports, one end of the lower thrust rod is fixed on the bridge body through the lower thrust rod seat, one end of the upper thrust rod is provided with a fixed block, and the fixed block is fixed with the bridge body through a bolt. The commercial bus rear suspension system with the structure reduces the overall weight of suspension, reduces the cost, is convenient for installing the upper thrust rod and optimizes the arrangement space of parts.

Description

Commercial passenger car rear suspension system

Technical Field

The utility model relates to a rear suspension system of a commercial bus.

Background

The rear suspension of the passenger car is a very important part in the whole passenger car and is used for fixing the rear axle of the passenger car to be connected with the car body. The existing rear suspension comprises a bridge body, wherein an airbag mounting structure and a support of a shock absorber are arranged on the bridge body, and an independent fixing seat body is continuously arranged on the support to fix the airbag mounting structure and the shock absorber, so that the overall weight of the suspension is increased, and the cost is higher; meanwhile, an upper thrust rod and a lower thrust rod are fixed on the existing bridge body through thrust rod supports respectively, and the upper thrust rod supports are fixed through multiple bolts, so that the fixing is inconvenient.

Disclosure of Invention

In view of the defects of the existing commercial bus rear suspension, the technical problems to be solved by the utility model are as follows: the overall weight of the rear suspension is reduced, and the production cost is reduced; meanwhile, the installation of the upper thrust rod is optimized, so that the installation is more convenient.

In order to achieve the above object, according to one aspect of the present utility model, the present utility model is achieved by the following technical means: a commercial passenger vehicle rear suspension system comprising: the bridge body, the welding has bumper shock absorber support and gasbag support on the bridge body, is fixed with the bumper shock absorber on the bumper shock absorber support, is fixed with the gasbag assembly on the gasbag support, still be equipped with upper thrust rod seat and lower thrust rod seat on the bridge body, be equipped with the upper thrust rod on the upper thrust rod seat, be equipped with lower thrust rod on the lower thrust rod seat.

This commercial passenger train rear suspension is through welding bumper shock absorber support and gasbag support direct on the bridge, has got rid of the support, makes the weight of whole suspension alleviate, has also reduced manufacturing cost simultaneously.

Further, the upper thrust rod seat is a fixed block with an internal thread at one end, and the internal thread end of the upper thrust rod seat is fixedly connected with the bridge body in a threaded manner through a bolt. The design is convenient for installing the upper thrust rod.

Compared with the prior art, the utility model has the advantages that: the whole weight of hanging is reduced, the cost is reduced, the installation of the upper thrust rod is convenient, and the arrangement space of parts is optimized.

Drawings

In the drawings:

fig. 1 is a schematic structural view of a rear suspension system of a commercial bus according to the present utility model.

Reference numerals illustrate: 1. a bridge body; 2. a shock absorber support; 3. an air bag support; 4. a damper; 5. an airbag assembly; 6. an upper thrust rod; 7. a lower thrust rod; 8. and a fixed block.

Detailed Description

The utility model will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

In the description of the present utility model, it should be understood that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "bottom," "top," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the utility model.

Example 1

Referring to fig. 1, the rear suspension system for a commercial bus provided in this embodiment includes a bridge 1, an air bag assembly 5, a damper 4, an upper thrust rod 6 and a lower thrust rod 7, where the bridge 1 is a straight rod, two sides of the bridge 1 are welded with a damper support 2 and an air bag support 3 respectively, the damper 4 and the air bag assembly 5 are fixed on the corresponding supports respectively, the upper thrust rod 6 and the lower thrust rod 7 are two groups, the two groups of upper thrust rod 6 and the lower thrust rod 7 are also separately arranged on two sides of the bridge 1, so that the structures of two sides of the bridge are identical, one end of the lower thrust rod 7 is fixed on the bridge 1 through a lower thrust rod seat, one end of the upper thrust rod 6 is fixed with a fixed block 8, and the fixed block 8 is provided with an internal threaded end and is screwed and fixed with the internal threaded end of the fixed block 8 through a bolt passing through the bridge 1.

The passenger car rear suspension system is the same as the existing passenger car rear suspension system in use, the whole weight of suspension is reduced through the design, the cost is reduced, the installation of the upper thrust rod is convenient, and meanwhile, the arrangement space of parts is optimized.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
