Description

Technical Field

[0001] The utility model relates to the field of shock absorbers, and particularly to a simple shock absorber upper support with a tight-fitting fixed structure. Background Art

[0002] As Figure 1 shown in the figure, the existing shock absorber upper support adopts an upper fixing plate (1') and a lower support plate (2') to accommodate and fix an elastic body (3') and an inner skeleton (4'). The fixing method for the elastic body is to compact and pre-tighten the lower part by the upper fixing plate, and the upper fixing plate and the lower support plate are fixed together by welding, riveting and other methods. The upper support is connected to the upper end of the shock absorber piston rod through the inner hole of the inner skeleton, and the whole upper support is connected to the vehicle through the mounting holes (5') or mounting bolts of the upper fixing plate and the lower support plate assembly.

[0003] The existing technology has the following defects:

[0004] 1. There are two metal plates, namely the upper fixing plate and the lower support plate, and relatively more materials are used.

[0005] 2. In order to fasten these plate parts, more processes are required, such as welding and riveting, and these processes will bring more costs and risk points in the process.

[0006] 3. Whether the fixing method for the internal elastic body is welding or riveting, there are relatively many process control requirements, and any risk in the control may lead to noise problems of the vehicle upper support.

[0007] 4. The welding process used in the process will have a certain impact on the elastic body material. Summary of the Utility Model

[0008] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a simple shock absorber upper support with a tight-fitting fixed structure, which simplifies the overall structure, reduces the use of metal materials, has more convenient processing technology, is applicable to some specific vehicle models, and improves the stability.

[0009] The purpose of the utility model is achieved by the following technical solutions: This simple shock absorber upper support with a tight-fitting fixed structure includes an elastic body, a support plate and a base. An outer skeleton is arranged on the outer periphery of the elastic body. The middle part of the support plate is recessed inward to form a receiving cavity, so that the elastic body is embedded and installed in the receiving cavity, and the elastic body is fixed by an interference fit between the outer skeleton and the inner wall of the support plate. An inner skeleton is arranged inside the elastic body, and an inner hole is penetrated through the inner skeleton for connecting the upper end of the shock absorber piston rod.

[0010] As a further technical solution, a base is fixed at the bottom of the support plate, and the inner cavity of the base is used to accommodate a buffer block.

[0011] As a further technical solution, a plurality of mounting holes are provided on the support plate along the circumferential direction for mounting bolts to connect with the whole vehicle.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. Cancel the scheme of fixing the internal elastic body of the upper support by two metal plates in the prior art, reducing the use of metal materials;

[0014] 2. Reduce the proportion of welding or riveting processes in processing, reducing the unstable factors and risks that may be caused during the manufacturing process;

[0015] 3. The elastic body and the support plate adopt an interference fit to avoid the high-temperature influence of welding on the elastic material;

[0016] 4. Only one support plate is provided, simplifying the structure of the upper support, reducing weight and saving space. Description of the Drawings

[0022] The following will introduce the present utility model in detail with reference to the drawings:

[0023] Embodiment: As shown in the attached Figure 2 、 3 figures, the simple shock absorber upper support with a tight fit fixing structure includes an elastic body 1, an inner skeleton 2, a support plate 3, a base 4, an outer skeleton 5, an inner hole 6, a mounting hole 7 and an accommodating cavity 8.

[0024] A circle of outer skeleton 5 is arranged on the outer periphery of the elastic body 1. At the same time, the middle part of the support plate 3 is recessed inward to form an accommodating cavity 8, and the elastic body 1 is embedded and installed in the accommodating cavity 8, so that the elastic body 1 forms an interference fit with the inner wall of the support plate 3 through its outer skeleton 5 to achieve fixation.

[0025] Furthermore, an inner skeleton 2 is arranged inside the elastomer 1. An inner hole 6 is formed through the inner skeleton 2. The upper end of the shock absorber piston rod passes through the support plate 3 and extends into the accommodation cavity 8, and is connected and locked with the inner hole 6, as Figure 3 shown.

[0026] Preferably, a base 4 is fixedly welded to the bottom of the support plate 3. The inner cavity of the base 4 can accommodate a buffer block. A plurality of mounting holes 7 are formed in the support plate 3 along the circumferential direction for mounting bolts to connect with the whole vehicle, as Figure 3 shown.

[0027] Compared with the prior art, the present utility model reduces a metal plate in structure, effectively saves materials, and achieves the purpose of weight reduction and space saving. After actual adoption, the production efficiency of parts is increased by more than 10%, the weight is reduced by 5%, the cost is reduced by 4-13%, and the contribution degree of space saving is 2-6%. In addition, the elastic member of the upper support is realized by a stable and reliable dimension fit and a tightly fitted press-fitting method with stable process, which can improve the avoidance effect on most noises. Since high-risk processes such as welding and riveting are cancelled during processing, the product consistency and reliability are improved.

[0028] It can be understood that for those skilled in the art, any equivalent replacement or change to the technical solution and the inventive concept of the present utility model should fall within the protection scope of the appended claims of the present utility model.
