Description

Technical Field

[0001] This utility model belongs to the field of vehicle equipment, and specifically relates to a vehicle shock absorber rod assembly. Background Technology

[0002] Figure 1 This diagram illustrates a piston rod assembly widely used in current vehicle shock absorbers, comprising a rod 1, a buffer pad 2, a stop block 3, and a retaining ring 4. The retaining ring 4 is typically installed via a groove structure 5 on the rod 1, which creates stress concentration at the groove structure 5, reducing the strength of the rod 1. During vehicle operation, in adverse road conditions, the piston rod 1 may break, thus compromising safety. Furthermore, the piston rod assembly, consisting of four parts, is structurally complex and has a high manufacturing cost.

[0003] Therefore, it is necessary to develop a new type of shock absorber rod assembly to improve strength, simplify structure, reduce cost, and enhance overall reliability and safety. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a vehicle shock absorber rod assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle shock absorber rod assembly, comprising a rod and a buffer pad, wherein the rod has an arc-shaped protrusion for providing a stopping effect during the movement of the shock absorber, and the buffer pad is installed at the arc-shaped protrusion of the rod and has an internal shape that cooperates with the arc-shaped protrusion.

[0006] Preferably, the outer shape of the cushioning pad has at least two corrugations.

[0007] Preferably, the cushioning pad is integrally molded.

[0008] Preferably, the cushioning pad is composed of a highly elastic and wear-resistant material.

[0009] Preferably, the arc-shaped protrusion is integrally formed with the rod.

[0010] Preferably, the surface of the arc-shaped protrusion is smooth and has no sharp points.

[0011] This invention uses an arc-shaped protrusion instead of a groove, which reduces stress concentration in the rod and increases its strength, thereby reducing the risk of rod breakage and improving safety; in addition, it reduces the number of parts, thereby reducing manufacturing costs. Attached Figure Description

[0012] Figure 1 This is a structural schematic diagram of a vehicle shock absorber rod assembly in the prior art;

[0013] Figure 2 This is a structural schematic diagram of the vehicle shock absorber rod assembly according to the present invention.

[0014] In the diagram: 1, 1' rod; 2, 2' buffer pad; 3 stop block; 4 stop ring; 5 groove structure; 6 arc-shaped protrusion; 7 corrugations. Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Figure 2 This is a structural schematic diagram of the vehicle shock absorber rod assembly according to the present invention.

[0017] Reference Figure 2 The vehicle shock absorber rod assembly according to this utility model includes only a rod 1' and a buffer pad 2', significantly reducing the number of parts compared to existing vehicle shock absorber rod assemblies. The rod 1' has an arc-shaped protrusion 6, which provides a stopping effect during shock absorber movement. Preferably, the arc-shaped protrusion 6 is integrally formed with the rod 1', and its surface is smooth and free of sharp points. Thus, the arc-shaped protrusion 6 replaces the stop and retaining ring found in the prior art, avoiding the need for grooves on the rod 1', thereby increasing the strength of the rod 1' and reducing stress concentration. Furthermore, the arc-shaped protrusion 6 typically has a smooth curved shape, which can be semi-circular, elliptical, or other types of curves.

[0018] The buffer pad 2' is mounted on the arcuate protrusion of the rod 1' and has an internal shape that mates with the arcuate protrusion 6. When the shock absorber reaches its limit stroke, the arcuate protrusion 6 interacts with the buffer pad 2' to provide the necessary restraint and cushioning. Preferably, the outer shape of the buffer pad 2' has at least two corrugations 7 to optimize damping performance under the ultimate tensile condition of the shock absorber. Preferably, the buffer pad 2' is integrally molded, and preferably, the buffer pad 2' can be composed of highly elastic and wear-resistant materials, such as rubber, thermoplastic elastomers, polyurethane, engineering plastics, hydraulic and pneumatic materials, etc.

[0019] In summary, this utility model uses an arc-shaped protrusion instead of a groove to reduce stress concentration in the rod and increase its strength, thereby reducing the risk of rod breakage and improving safety; in addition, it reduces the number of parts, thereby reducing manufacturing costs.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
