[0059] As shown in Figure 3 、 Figure 4 、 Figure 6 and Figure 7 , the circumferential edge of the top support 2 extends outwardly to be provided with a fixing portion 211, and the top support 2 comprises a plurality of fastener press fitting holes 26 arranged in the circumferential direction of the fixing portion 211, which are used for press fitting fasteners 27, that is to say, the fasteners 27 can be press fitted into the fastener press fitting holes 26 by interference, and are fixed with the vehicle body through the fasteners 27.

[0060] For vehicles of different brands or different models, the structure of the vehicle body for mounting the shock absorber assembly can be different, and the top support 2 is provided with the fastener press fitting holes 26, which can be as shown in Figure 3 and Figure 4 , the fasteners 27 are bolts, the bolts are press fitted into the fastener press fitting holes 26, and are fixed with the vehicle body through the bolts, or as shown in Figure 6 and Figure 7As shown, the fastener 27 is a nut, the nut is pressed into the fastener press-fit hole 26, and is fixed to the vehicle body through the nut, so as to improve the expandability of the shock absorber assembly and the vehicle installation, and the specific switching can be performed according to the assembly requirements, without replacing other components of the shock absorber, thereby facilitating the batch production of the shock absorber assembly, and facilitating the shock absorber assembly to be set as a standard part to reduce the production cost.

[0061] Moreover, since the fastener press-fit hole 26 is fixed to the bolt or the nut through interference press fitting, the accuracy of each fastener press-fit hole 26 is designed according to the design requirements, so as to ensure the installation accuracy and reliability of the shock absorber assembly and the vehicle.

[0062] Compared with the scheme in which the top support 2 is provided with a threaded hole, fixed to the vehicle body through the threaded hole by screwing the bolt and the threaded hole, and fixed to the vehicle body through the bolt, the scheme in which the top support 2 is provided with the fastener press-fit hole 26 can realize the fixing to the vehicle body through the bolt and the fixing to the vehicle body through the nut to improve the expandability, and can also effectively ensure the installation accuracy and reliability.

[0063] As shown in Figure 4 and Figure 7 The top support 2 includes a support framework 21, a cover plate 22 and a bushing 23, wherein the bushing 23 is embedded with a partition plate 24 and a nylon clamping piece 25, the nylon clamping piece 25 is wrapped outside the partition plate 24, the support framework 21 is provided with a mounting groove, the bushing 23 is arranged in the mounting groove of the support framework 21, and the cover plate 22 is covered on the slot opening of the mounting groove and can press the bushing 23 to ensure the installation stability of the bushing 23 in the support framework 21.

[0064] The nylon clamping piece 25 is wrapped outside the partition plate 24 and is fixed as an integral structure with the bushing 23 through vulcanization, then the bushing is integrally press-fitted into the mounting groove, and finally the cover plate 22 is installed, and the cover plate 22 and the support framework 21 can be fixed through spin riveting. The setting of the nylon clamping piece 25 facilitates the adjustment of the rigidity of the bushing 23, when the required rigidity is different, the partition plate 24 does not need to be replaced, and only the nylon clamping piece 25 with the corresponding thickness needs to be used to adjust the static and dynamic characteristics of the top support 2, compared with adjusting the rigidity of the bushing 23 by replacing the partition plate 24 with different thicknesses, the universality of the partition plate 24 can be improved, and the cost can be reduced.

[0065] As shown in Figure 2 The top support 2 is fixed to the column 8 through the connecting nut 13, specifically, the top end of the column 8 is provided with a threaded segment, the top end of the column 8 passes through the top support 2, and cooperates with the connecting nut 13 to realize the fixation.

[0066] As shown in Figure 8 , the upper spring pad 3 includes a first plastic skeleton 31 and a rubber part, wherein the rubber part is vulcanized on the first plastic skeleton 31, and the upper spring pad 3 is designed with a lift matching the spring 5. The first plastic skeleton 31 is provided with a matching groove 33, and the support skeleton 21 of the top support 2 is provided with a matching boss 28. During installation, the top of the upper spring pad 3 is attached to the bottom of the top support 2, and the matching boss 28 and the matching groove 33 are matched to limit the rotation of the upper spring pad 3. Of course, the support skeleton 21 can also be provided with a matching groove, and the first plastic skeleton 31 can be provided with a matching boss.

[0067] As shown in Figure 9 , the lower spring pad 6 is supported on the spring disc 7 by the spring 5. Specifically, as shown in Figure 11 , the lower spring pad 6 includes a second plastic skeleton 61 and a second rubber part 62, and the second rubber part 62 is vulcanized and fixed to the second plastic skeleton 61. The lower spring pad 6 is designed with a lift matching the spring 5, and the upper surface of the lower spring pad 6 is provided with a guide cylinder 63 along the inner edge, and is also provided with a limiting structure 64 along the outer edge. The limiting structure 64 and the guide cylinder 63 form a limiting groove 65 therebetween, the bottom of the spring 5 is sleeved outside the guide cylinder 63, and the spring 5 is at least partially located in the limiting groove 65 in the circumferential direction to limit the movement of the spring 5 in the radial direction, ensuring the stability of the spring 5 and improving the overall reliability of the shock absorber assembly.

[0068] The upper surface of the lower spring pad 6 is also provided with a protruding portion 66 in the circumferential direction, and the end of the bottom wire of the spring 5 can abut against the protruding portion 66 to limit the rotation of the spring 5. Specifically, during installation, the spring 5 is rotated so that the end of the bottom wire abuts against the protruding portion 66. The spring 5 has good stability and can ensure the overall reliability of the shock absorber.

[0069] The lower spring pad 6 is sleeved outside the column 8 and can rotate relative to the column 8. By rotating the lower spring pad 6 to adjust the cooperation with the spring 5, the design freedom of the spring 5 is released, and the flexibility is better.

The lower spring pad 6 is sleeved outside the support ring 9 and is in interference fit with the support ring 9, and the support ring 9 can limit the radial movement of the lower spring pad 6. Moreover, when different sizes of columns 8 are used, the lower spring pad 6 can be replaced without replacement, and only the corresponding support ring 9 needs to be replaced, which ensures the universality of the lower spring pad 6.

[0071] In addition, as shown in Figure 13As shown, the column 8 is fitted with a cover 10, and the outer diameter of the support ring 9 is not less than the outer diameter of the cover 10. That is to say, the outer diameter of the lower spring pad 6 is greater than the outer diameter of the cover 10. With this setting, if the lower spring pad 6 is damaged or needs to be replaced after a period of use, the lower spring pad 6 can be directly disassembled from the support ring 9. The lower spring pad 6 can move along the axial direction of the column 8 and pass through the cover 10 to realize the installation and removal of the lower spring pad 6. The cover 10 does not need to be disassembled, which makes the operation more convenient.

[0072] And, as Figure 10 and Figure 12 As shown, the bottom edge of the support ring 9 is further provided with a flange structure 91 extending radially outward. The lower spring pad 6 can press the flange structure 91, so that the flange structure 91 is clamped between the lower spring pad 6 and the spring plate 7, thereby axially limiting the support ring 9. Specifically, the bottom surface of the lower spring pad 6 is also provided with a groove that matches the flange structure 91 along the inner circumferential direction. During installation, the bottom surface of the lower spring pad 6 abuts against the spring plate 7, and the flange structure 91 is located in the space enclosed between the bottom of the groove and the spring plate 7.

[0073] The spring disc 7 and the column 8 can be fixed by welding. Different springs 5 ​​can be designed according to different vehicle postures, curb weights and suspension dynamic characteristics. When using the shock absorber assembly provided in this embodiment, only the welding position of the spring disc 7 needs to be adjusted to adjust the distance between the upper spring pad 3 and the lower spring pad 6 to accommodate springs 5 ​​of different lengths, which provides a high degree of design freedom.

[0074] like Figure 10 As shown, the cross-section of the spring disc 7 is similar to a U-shape. The upper surface of the spring disc 7 is a flat structure to facilitate contact with the lower spring pad 6 and the support ring 9. The inner and outer edges of the spring disc 7 are respectively provided with downward-facing flanges to ensure the structural strength and stability of the spring disc 7. Specifically, the flange on the inner edge forms a cylindrical structure that fits over the column 8, and the flange on the inner edge can be welded and fixed to the column 8. Furthermore, the downward-facing flanges also facilitate the timely drainage of water and other substances.

[0075] The upper spring pad 3 includes a first plastic frame and a first rubber component 32, the first rubber component 32 being fixed to the first plastic frame by vulcanization. The lower spring pad 6 includes a second plastic frame and a second rubber component 62, the second rubber component 62 being fixed to the second plastic frame by vulcanization. This configuration allows for a lighter structure while meeting performance requirements, facilitating weight reduction.

[0076] The cylinder 8 comprises a cylinder body 81 and a rod body 82, the rod body 82 is located in the cylinder body 81, one end of the cylinder body 81 can extend out of the cylinder body 81 and can move along the axial direction relative to the cylinder body 81, the cover 10 is sleeved outside the cylinder 8, the cover 10 is fixed on the end of the cylinder body 81 by press fitting, the rod body 82 passes through the cover 10, the cover 10 can provide protection for the oil seal in the cylinder 8 to prevent dust from entering, thereby ensuring smooth movement of the rod body 82 relative to the cylinder body 81.

[0077] The shock absorber assembly further comprises a dust cover 4, as shown in Figure 15 and Figure 16 , the top end of the dust cover 4 is provided with an extension edge 41 extending radially outward, the upper spring pad 3 is sleeved outside the dust cover 4, and the extension edge 41 is clamped between the upper spring pad 3 and the top support 2, the outer peripheral wall of the cover 10 is further provided with a first clamping piece 101 (as shown in Figure 14 ), the inner peripheral wall of the dust cover 4 is further provided with a second clamping piece 42, the first clamping piece 101 and the second clamping piece 42 are clamped and limit the upward movement of the dust cover 4, to ensure the stable position of the dust cover 4, thereby ensuring the dustproof effect of the dust cover 4.

[0078] The shock absorber assembly further comprises a dust cover 4, as shown in Figure 1 and Figure 2 and Figure 16 , the dust cover 1 is arranged at the top of the shock absorber assembly, and is clamped and fixed with the top support 2 by means of buckling, specifically, the dust cover 1 can be provided with clamping protrusions, and the first plastic framework 31 or the upper cover of the top support 2 can be provided with clamping grooves, or the dust cover 1 can be provided with clamping grooves, and the first plastic framework 31 or the upper cover of the top support 2 can be provided with clamping protrusions.

[0079] As shown in Figure 13 , the shock absorber assembly further comprises a limiting piece 12, the limiting piece 12 is fixed on the outer wall of the cylinder 8, specifically by welding, and is used for limiting and positioning the installation of the shock absorber assembly, and the included angle between the axis of one of the fastening holes 26 and the circumferential direction of the cylinder 8 is a fixed angle, which can facilitate positioning of the shock absorber assembly during installation.

[0080] As shown in Figure 13 and Figure 18As shown, the limiting sheet 12 is provided with a limiting protrusion 121, which is inserted into the longitudinal through hole of the lower fork arm 15 after the shock absorber assembly is assembled in place, and the limiting protrusion 121 of the limiting sheet 12 is inserted into the slot of the through hole of the lower fork arm 15 to limit the rotation of the shock absorber assembly. After the lower end surface of the column body 8 is attached to the lower end surface of the longitudinal through hole of the lower fork arm 15, a bolt and nut are used for fastening, and the shock absorber assembly is clamped and fixed by the deformation of the slot structure of the longitudinal through hole of the lower fork arm 15. In the case of failure of the bolt and nut, or when the lower end of the longitudinal through hole of the lower fork arm 15 loses the function of providing axial limiting of the shock absorber assembly, the limiting sheet 12 can also axially position the assembly of the shock absorber assembly and the lower fork arm 15, providing a safe redundant effect. At the same time, the circumferential positioning of the shock absorber by the limiting sheet 12 can also prevent errors during the assembly of the shock absorber assembly and the lower fork arm 15.
