Description

Technical Field

[0001] This utility model relates to an air suspension modification shock absorber, and in particular to an air spring with built-in buffer block structure. Background Technology

[0002] Traditional designs use a fixed height buffer block, which prevents customers from adjusting the travel according to their own needs and has poor versatility across different vehicle models. Summary of the Invention

[0003] To solve the aforementioned technical problem of the inability to adjust the stroke, this utility model provides an air spring with a built-in buffer block structure.

[0004] The technical solution of this utility model is as follows: An air spring with built-in buffer block structure includes a connecting rod, a buffer block, an air spring top cover, and a shock absorber. The left side of the shock absorber is fitted into the lower cover of the air spring, and the left end of the shock absorber is provided with a connecting rod that passes through the upper cover of the air spring. The upper cover of the air spring is fixed to the top of the cover, and at least one buffer block is sleeved in the connecting rod.

[0005] The air spring cover is fixed to the upper ring by countersunk hex bolts.

[0006] The upper diameter of the connecting rod is smaller than the lower diameter, and a limiting nut is provided at the top of the connecting rod.

[0007] The diameter of the middle part of the cover is larger than the diameters of the upper and lower parts. The upper part of the inner wall of the cover is provided with an upper ring, and the lower part of the inner wall is provided with a lower ring.

[0008] The buffer block is ring-shaped with smooth upper and lower surfaces.

[0009] The technical solution of this utility model has a novel structure, ingenious and simple design, and adjustable design for increasing or decreasing the number of buffer blocks. This reduces the mold opening cost for buffer blocks of different heights, simplifies assembly, and makes the product highly versatile. The buffer blocks are made of polyurethane material, which can provide good cushioning when the shock absorber bottoms out, resulting in excellent riding comfort. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the structure of the buffer block in this utility model. Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0012] like Figure 1 , 2The air spring with built-in buffer block structure shown includes a connecting rod, a buffer block 1, an air spring upper cover 3, and a shock absorber 7. The shock absorber 7 is fitted into the air spring lower cover 8 on the left side. A connecting rod 5 is provided at the left end of the shock absorber 7. The connecting rod 5 passes through the air spring upper cover 3. The air spring upper cover 3 is fixed to the top of the cover 2. At least one buffer block 1 is sleeved in the connecting rod 5. The number of buffer blocks 1 is 4.

[0013] The air spring cover 3 is fixed to the upper ring by a countersunk hex bolt 4.

[0014] The upper diameter of the connecting rod is smaller than the lower diameter, and a limiting nut 6 is provided at the top of the connecting rod.

[0015] The diameter of the middle part of the cover 2 is larger than the diameter of the upper and lower parts. The upper part of the inner wall of the cover 2 is provided with an upper ring, and the lower part of the inner wall is provided with a lower ring.

[0016] The buffer block is ring-shaped with smooth upper and lower surfaces.

[0017] When using it, users can fit the corresponding number of buffer blocks on the connecting rod according to their needs when installing it on the vehicle. Multiple blocks fit together on the top and bottom to improve the effect. Then, the air spring cover is fixed with 6 hexagon countersunk bolts. Finally, the vehicle is installed and tested. A chamber is formed inside the cover 2. Users can add or remove buffer blocks to adjust the shock absorber stroke according to their needs.

[0018] It should be understood that the above description is only a preferred embodiment of the present utility model and is not sufficient to limit the technical solution of the present utility model. For those skilled in the art, within the spirit and principles of the present utility model, additions, subtractions, substitutions, transformations or improvements can be made based on the above description, and all such additions, subtractions, substitutions or improvements should fall within the protection scope of the appended claims of the present utility model.
