Figure 3 The cross-sectional structure of the positioning ring of the vibration damper in the embodiment of the utility model is shown. Figure 4 The structure of the outer cylinder of the lateral vibration damper in the embodiment of the utility model is schematically shown. Figure 5 The structure of the locating ring and the lateral vibration damper in the embodiment of the utility model is shown; Figures 1 to 5 As shown, the positioning ring 10 of the shock absorber provided by the embodiment of the utility model includes:

[0027] An annular body 11;

[0028] A protrusion 12 is provided on the outer wall of the annular body 11, and the protrusion 12 is provided with an anti-rotation concave surface 120;

[0029] A reinforcing rib 13 is disposed on the outer wall of the annular body 11 and spaced apart from the protrusion 12. The reinforcing rib 13 is radially outwardly protruding relative to the annular body 11.

[0030] The assembly groove 14 is provided on the end surface of the annular body 11 .

[0031] The annular body 11 is used to be sleeved on the bottom end of the inner tube 20 of the shock absorber, and the protrusion 12 of the positioning ring 10 is used to cooperate with the pit 33 of the outer tube 30 of the shock absorber, and the anti-rotation limit of the outer tube 30 is realized by the anti-rotation concave surface 120 of the protrusion 12; the reinforcing rib 13 is used to increase the rigidity of the parts, and the reinforcing rib 13 is radially convex relative to the annular body 11, and the outer contour of the reinforcing rib 13 is used to cooperate with the inner wall of the outer tube 30 to achieve positioning; the assembly groove 14 arranged on the end face of the annular body 11 is used for the bottom valve 40 to be assembled on the bottom end of the inner tube 20, so that the bottom valve 40 is assembled and fixed to the positioning ring 10.

[0032] Therefore, the positioning ring 10 of the shock absorber provided by the utility model effectively fixes the inner cylinder 20, the outer cylinder 30 and the bottom valve 40 of the shock absorber through the protrusion 12, the reinforcing rib 13 and the assembly groove 14 formed on the annular body 11, so as to stabilize the overall structure of the shock absorber, limit the rotation of the bottom valve 40, avoid the position deviation of the oil hole on the valve body, make the oil flow between the inner and outer cylinders of the shock absorber smooth, and keep the damping stable, which is particularly suitable for lateral shock absorbers.

[0033] It should be noted that Figure 4 and Figure 5 The lateral shock absorber is used as an example for demonstration and explanation. The outer cylinder 30 of the lateral shock absorber is formed with a pit 33 for identifying the installation direction. The protrusion 12 of the positioning ring 10 and the pit 33 of the outer cylinder 30 are anti-rotationally matched, and the reinforcing ribs 13 and the assembly grooves 14 are combined to achieve the stabilization of the inner and outer cylinders and the bottom valve 40 of the lateral shock absorber by the positioning ring 10. In other types of double-cylinder shock absorbers, if the outer cylinder is formed with a structure similar to the pit 33, the positioning ring 10 of the utility model can also be applied to achieve the stable anti-rotation function of the inner and outer cylinders and the bottom valve fixing function.

[0034] In some embodiments, the anti-rotation concave surface 120 is formed as an eccentric arc surface. The eccentric arc surface can realize the anti-rotation cooperation between the protrusion 12 of the positioning ring 10 and the pit 33 of the outer cylinder 30 and facilitate the assembly of the positioning ring 10 and the outer cylinder 30.

[0035] In some embodiments, the surface of the reinforcing rib 13 is formed into an arc surface, so as to facilitate the assembly of the positioning ring 10 and the outer cylinder 30 and avoid scratches on the outer cylinder 30 caused by the contact and cooperation between the positioning ring 10 and the outer cylinder 30 .

[0036] In some embodiments, the reinforcing ribs 13 include a plurality of reinforcing ribs 13 distributed at intervals along the circumferential direction, and an oil channel 130 is formed between two adjacent reinforcing ribs 13 .

[0037] By means of a plurality of reinforcing ribs 13 and oil channels 130 formed between the reinforcing ribs 13, the structure of the annular body 11 is evenly and stably reinforced, and a stable fit is achieved between the annular body 11 and the outer cylinder 30, thereby achieving the purpose of lightweight design and facilitating better flow of oil between the inner cylinder 20 and the outer cylinder 30 of the shock absorber.

[0038] In some embodiments, the assembly groove 14 is axially concave relative to the annular body 11. In this way, the assembly groove 14 extends toward the bottom valve 40 to facilitate the assembly of the bottom valve 40.

[0039] In some embodiments, the positioning ring 10 is a plastic positioning ring, so that the positioning ring 10 is easy to process and shape.

[0040] The utility model also provides a lateral vibration damper, combined with Figures 1 to 5 As shown, the lateral vibration damper comprises:

[0041] An inner cylinder 20 and an outer cylinder 30 that are coaxial and clearance-matched;

[0044] The outer cylinder 30 of the lateral vibration damper is formed with a pit 33 for identifying the installation direction of the bottom valve 40. The anti-rotation cooperation between the protrusion 12 of the positioning ring 10 and the pit 33 of the outer cylinder 30, combined with the reinforcing rib 13 and the assembly groove 14, realizes the stable anti-rotation function of the inner and outer cylinders and the fixing function of the bottom valve 40. Therefore, the lateral vibration damper equipped with the positioning ring 10 has a stable overall structure, smooth oil flow between the inner and outer cylinders, stable damping performance, and the lateral vibration damper has a good damping effect.

[0045] In some embodiments, the lateral vibration damper further includes: a bottom cover 50 , which seals and covers the end of the positioning ring 10 and seals and cooperates with the bottom end of the outer cylinder 30 .

[0046] The bottom cover 50 seals the positioning ring 10 and seals with the outer cylinder 30 to seal the oil in the lateral shock absorber.

[0047] In summary, the positioning ring 10 of the shock absorber provided by the utility model effectively fixes the inner cylinder 20, the outer cylinder 30 and the bottom valve 40 of the shock absorber through the protrusion 12, the reinforcing rib 13 and the assembly groove 14 formed on the annular body 11, so as to stabilize the overall structure of the shock absorber, limit the rotation of the bottom valve 40, avoid the position deviation of the oil hole on the valve body, and make the oil flow between the inner and outer cylinders of the shock absorber smooth, and keep the damping stable, which is particularly suitable for lateral shock absorbers.
