Description

Technical Field

[0001] This utility model relates to the field of shock absorbers for modified passenger cars, and in particular to a shock absorber core positioning sleeve structure. Background Technology

[0002] Traditional modified car shock absorber mechanisms have a bottom-out design, resulting in high material waste during idle stroke and higher costs. Summary of the Invention

[0003] To address the aforementioned technical problem of high material waste, this utility model provides a shock absorber core positioning sleeve structure.

[0004] The technical solution of this utility model is as follows: A shock absorber core positioning sleeve structure includes a positioning sleeve and a liquid storage cylinder. The inner wall of the liquid storage cylinder is provided with a core, and the positioning sleeve is provided on the rear side of the core. The inner wall of the positioning sleeve is provided with an embedded bushing. The inner side of the positioning sleeve is hollow, and a rubber bushing is provided on the right side of the bottom cover.

[0005] The positioning sleeve has an iron insert embedded in the inner wall on the left side. The outer wall of the iron insert has a groove, which is engaged with the convex ring. The inner wall of the iron insert has an inclined wall. The outer wall of the positioning sleeve has an end face, and the angle between the end face and the outer wall of the positioning sleeve is 45°. The positioning sleeve and the iron insert are integrally formed.

[0006] The inner wall of the bushing is in close contact with the outer right wall of the positioning sleeve, the outer wall of the bottom cover is press-fitted with the inner wall of the liquid storage cylinder, and the outer right wall of the bottom cover is welded and fixed.

[0007] The technical solution of this utility model has a novel structure, ingenious and simple design, and a shortened mechanism, which reduces the cost of liquid storage tank, working cylinder, piston rod and oil volume. The product has high versatility and saves costs. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural schematic diagram of the iron insert of this utility model; Figure 3 This is a structural diagram of the present invention in its installed state. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0010] like Figure 1 , 2The shock absorber core positioning sleeve structure shown in Figure 3 includes a positioning sleeve 1 and a liquid storage cylinder 5. The inner wall of the liquid storage cylinder 5 is provided with a core 6, the rear side of the core 6 is provided with the positioning sleeve 1, the outer wall of the positioning sleeve 1 is provided with a bottom cover 7, the inner side of the positioning sleeve 1 is hollow, and the outer wall of the bottom cover 7 is provided with a rubber bushing 10.

[0011] The positioning sleeve 1 has an iron insert 4 embedded in the inner wall on the left side. The outer wall of the iron insert 4 has a groove, which is engaged with the convex ring 3. The inner wall of the iron insert 4 has an inclined wall. The outer wall of the positioning sleeve 1 has an end face 2. The angle between the end face and the outer wall of the positioning sleeve 1 is 45°. The positioning sleeve 1 and the iron insert 4 are integrally formed.

[0012] The inner wall of the bottom cover 7 is tightly attached to the outer right side wall of the positioning sleeve 1, the outer wall of the bottom cover 7 is press-fitted to the inner wall of the liquid storage cylinder 5, and the outer right side wall of the bottom cover 7 is welded and fixed.

[0013] In use, the positioning sleeve assembly is injection molded, with a 45° bushing at the head. Shock absorber internal assembly: First, place the positioning sleeve inside the reservoir assembly, then place the mechanism inside, and finally tighten the nut body 14 with a torque of 120 N / M. The outer wall of the reservoir 5 is equipped with an adjusting nut 11, a spring seat 13, and a spring. A buffer block 15 and a dust cover 16 are located on the left side of the nut body 14. A spring pressure cap 17 is located on the left side of the buffer block 15, passing through a fixing rod and secured by a nut. It uses 30% reinforced PP material, and the 45° bushing at the head ensures the strength of the components and prevents deformation that could cause the mechanism to loosen. The positioning sleeve design allows for a shorter mechanism length while maintaining the shock absorber's stroke, reducing costs.

[0014] 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.
