Description

Technical Field

[0001] This utility model belongs to the technical field of shock absorber accessories, specifically relating to a motorcycle shock absorber upper hanging ring. Background Technology

[0002] The rear shock absorber is used to support the weight of the frame, mitigate vibrations and impacts from uneven road surfaces, rapidly dampen vibrations, improve riding comfort, reduce dynamic stress in various parts of the vehicle, and extend the vehicle's lifespan. In existing technology, motorcycles use a connecting rod, piston, and rear shock absorber shackle connector to form a moving part, while the outer and inner cylinders form an integral moving part, connected to the rear swingarm via the shackle connector, joint, and frame, respectively.

[0003] For example, the rear shock absorber eyelet connector disclosed in application number CN201420760744.9 has an eyelet connection end at one end and a damper connection end at the other end, suitable for connecting the connecting rod of the damping device in the rear shock absorber; the eyelet connection end is provided with an eyelet suitable for connecting to the motorcycle frame; the damper connection end is provided with an internal threaded hole; the rear shock absorber eyelet connector is integrally formed. In this patent, because the rear shock absorber eyelet connector is integrally formed, the process is simple and the mold scrap rate is low; because the rear shock absorber eyelet connector is an integral aluminum casting, the low melting point of aluminum can improve the internal quality, dimensional accuracy, surface finish, and production efficiency of the casting.

[0004] However, the bottom of the internal threaded hole in the lifting ring connector lacks a guide and positioning structure, which makes it easy for the piston rod to loosen and shift after being connected to the internal threaded hole. At the same time, there is also no space at the top of the internal threaded hole to assemble the adjustment knob. Utility Model Content

[0005] Based on the problems mentioned in the background art above, this utility model provides a motorcycle shock absorber upper ring to solve the problem that the bottom of the internal threaded hole in the above-mentioned ring connector lacks a guide positioning structure, which makes it easy for the piston rod to loosen and shift after being connected to the internal threaded hole. At the same time, there is also a lack of space at the top of the internal threaded hole to assemble the adjustment knob.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A motorcycle shock absorber upper swivel, comprising:

[0008] Shoulder body;

[0009] The lifting eye portion is integrally formed with the shoulder body and the lifting eye portion through a connecting part, and the lifting eye portion is provided with a sleeve hole;

[0010] A connection assembly hole is provided in the shoulder body and the connecting part. The connection assembly hole includes a threaded hole and a stepped hole, with the threaded hole located at the top of the stepped hole.

[0011] Assembly cavity, which is located at the top of the threaded hole.

[0012] Based on the above technical solution, the present invention has made the following improvements:

[0013] Furthermore, the assembly cavity includes a slot, which is located at the top of the threaded hole and communicates with the threaded hole. The two ends of the slot penetrate the outer side walls of the lifting ring portion, and a positioning groove is provided on the top wall of the slot.

[0014] Furthermore, the upper diameter of the stepped hole is smaller than the lower diameter, and the major diameter of the threaded hole is smaller than the upper diameter of the stepped hole.

[0015] Furthermore, the middle part of the sleeve hole is a cylindrical hole, and the two ends are flared holes.

[0016] Furthermore, the cross-sectional profile of the lifting ring is drum-shaped.

[0017] The beneficial effects of this utility model are:

[0018] The connection assembly holes include threaded holes and stepped holes. The threaded holes are located at the top of the stepped holes. During assembly, the top thread of the piston rod of the damping device in the rear shock absorber is screwed into the threaded hole, and the stepped shoulder on the piston rod is locked in the stepped hole. This allows the upper lifting ring to be assembled onto the top of the piston rod of the damping device in the rear shock absorber. The stepped holes also guide the piston rod as it is screwed in, and once screwed in, the stepped shoulder on the piston rod is locked in the stepped hole, thus positioning the piston rod. The assembly cavity can accommodate and install the adjustment knob. Attached Figure Description

[0027] like Figures 1-5 As shown, a motorcycle shock absorber upper swivel includes:

[0028] The shoulder body 101 and the eyelet part 103 are integrally formed by the connecting part 102. The eyelet part 103 is provided with a sleeve hole 104. The sleeve hole 104 is used to connect the guide tube of the motorcycle frame. A rubber sleeve is also provided between the sleeve hole 104 and the guide tube to prevent the guide tube of the motorcycle frame from directly contacting the sleeve hole 104 and causing a hard collision. The middle part of the sleeve hole 104 is a cylindrical hole and the two ends are flared holes, which can prevent the rubber sleeve from falling off the opening of the sleeve hole 104 after it is inserted into the sleeve hole 104.

[0029] The connection assembly hole is located within the shoulder body 101 and the connecting part 102. The connection assembly hole includes a threaded hole 201 and a stepped hole 202. The threaded hole 201 is located at the top of the stepped hole 202, and the upper diameter of the stepped hole 202 is smaller than the lower diameter. The major diameter of the threaded hole 201 is smaller than the upper diameter of the stepped hole 202. During assembly, the piston rod of the damping device in the rear shock absorber is screwed into the threaded hole 201 through the thread, and the stepped shoulder on the piston rod is engaged in the stepped hole 202. This allows the upper lifting ring to be assembled onto the top of the piston rod of the damping device in the rear shock absorber. Due to the cooperation between the stepped hole 202 and the stepped shoulder on the piston rod, the piston rod can be guided when screwed in. After being screwed in, the stepped shoulder on the piston rod can be engaged in the stepped hole 202, thus positioning the piston rod.

[0030] The assembly cavity is located at the top of the threaded hole 201 and includes a slot 301. The slot 301 is located at the top of the threaded hole 201 and communicates with the threaded hole 201. The two ends of the slot 301 pass through the outer side walls of the lifting ring part 103 respectively. A positioning groove 302 is provided on the top wall of the slot 301. During assembly, the adjustment knob can be assembled in the slot 301, and the valve core in the piston rod of the damping device in the rear shock absorber is placed against the hole in the middle of the adjustment knob, so that the top of the valve core extends into the positioning groove 302, thereby achieving stable assembly of the adjustment knob in the slot 301.

[0031] The cross-sectional profile of the lifting ring 103 is drum-shaped to avoid having too many sharp edges on the outer contour of the lifting ring 103.

[0032] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of ​​the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
