[0001] The utility model relates to the technical field of motorcycle rear shock absorbers, and specifically relates to a replaceable rear shock absorber for a motorcycle. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after absorbing shock and the impact from the road surface. They are widely used in vehicles such as cars and motorcycles to accelerate the attenuation of frame and body vibrations to improve the ride smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] The existing rear shock absorber is directly fixed to the rear bracket of the motorcycle by bolts. However, the outer shell of some motorcycles will block the rear shock absorber. Therefore, when replacing the rear shock absorber, the outer shell of the motorcycle needs to be disassembled first, which is relatively complicated. At the same time, different motorcycle models have different requirements for the specifications of the rear shock absorber. Therefore, when replacing, it is necessary to install an adapted rear shock absorber. When temporarily replacing the shock absorber, there are many inconveniences, and the use effect of the rear shock absorber is affected. For this reason, a replaceable rear shock absorber for motorcycles is proposed, which solves the above problems by using a first rotating plate and a second rotating plate with a diamond structure.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1~Figure 3 As shown, a replaceable rear shock absorber for motorcycle comprises a rear shock absorber body 1, the top end of the rear shock absorber body 1 is fixedly connected with an upper connecting column 2, the outer end of the upper connecting column 2 is provided with an adjustment assembly 3, the adjustment assembly 3 comprises a first rotating plate 301 symmetrically rotatably connected to the outer end of the upper connecting column 2, the outer end of the first rotating plate 301 is rotatably connected with a second rotating plate 302, the outer ends of the two first rotating plates 301 and the second rotating plates 302 are both rotatably connected with connecting plates 303, a screw rod 304 is rotatably connected between the two connecting plates 303, the outer end of the connecting plate 303 is fixedly connected with a nut 305, and the screw 304 and the nut 305 are threadedly connected. The purpose of this arrangement is that the two sets of first rotating plates 301 and second rotating plates 302 are telescopic, and during disassembly, it is convenient to extend the connecting column 306 from the outer shell of the motorcycle, thereby facilitating the disassembly and replacement of the rear shock absorber body 1. The screw rod 304 is used to adjust the spacing between the two nuts 305, thereby adjusting the vertical spacing between the two sets of first rotating plates 301 and the second rotating plates 302. On the one hand, during disassembly, it is convenient to extend the connecting column 306 from the shell of the motorcycle, and the rear shock absorber body 1 can be replaced without disassembling the shell of the motorcycle, which makes the operation easier.

[0023] Preferably, a spacing is provided between the two first rotating plates 301 and the second rotating plates 302 and the two rotating plates 302 are in a diamond-shaped structure, two sets of threads are provided at the outer end of the screw rod 304 and are arranged in opposite directions, and a hexagonal column is fixedly connected to the center of the screw rod 304. The purpose of this arrangement is that the two sets of first rotating plates 301 and the second rotating plates 302 in a diamond-shaped structure enhance the stability of the rear shock absorber body 1, and the two sets of threads at the outer end of the screw rod 304 are arranged in opposite directions, so that the two connecting pieces 303 move in opposite directions.

[0024] Preferably, the adjustment assembly 3 further comprises a connecting column 306 rotatably connected to the inner side of the connection between one set of the first rotating plate 301 and the second rotating plate 302, and a clamping hole is provided at the top of the connecting column 306. The purpose of this arrangement is that the connecting column 306 is used to connect to the rear bracket of the motorcycle, and the clamping hole is used to connect to the clamping rod of the rear bracket of the motorcycle.

[0025] In this embodiment, before assembling the rear shock absorber body 1, the connecting column 306 is first clamped in the clamping rod on the rear bracket of the motorcycle. When installing the rear shock absorber body 1, the upper connecting column 2 of the rear shock absorber body 1 is connected to the connection between one group of the first rotating plate 301 and the second rotating plate 302, and fixed with the upper fixing bolt 4. When it is necessary to disassemble the rear shock absorber body 1, the screw rod 304 is rotated, and the screw rod 304 rotates inside the nut 305, so that the two connecting pieces 303 slide towards each other, thereby adjusting the vertical spacing between the two groups of the first rotating plates 301 and the second rotating plates 302, so that the connecting column 306 extends out from the inside of the motorcycle shell, thereby facilitating the replacement of the rear shock absorber body 1. At the same time, when it is necessary to temporarily replace the rear shock absorber body 1, due to the large number of vehicle models, the temporary rear shock absorber body 1 is difficult to adapt to the motorcycle. At this time, the vertical spacing between the two groups of the first rotating plates 301 and the second rotating plates 302 is adjusted to enhance the stability of the installation of the rear shock absorber body 1 and the motorcycle bracket.

[0026] Example 2

[0027] like Figure 1~Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that another set of upper fixing bolts 4 are movably connected at the connection between the first rotating plate 301 and the second rotating plate 302, and the bottom end of the rear shock absorber body 1 is fixedly connected with a lower connecting column 5. The purpose of this arrangement is that the upper fixing bolts 4 are used to install the rear shock absorber body 1 at the connection between the first rotating plate 301 and the second rotating plate 302.

[0028] Preferably, the outer end of the lower connecting column 5 is rotatably connected with a gasket 6, the gasket 6 is bent, and a lower fixing bolt 7 is movably connected between the lower connecting column 5 and the gasket 6. The purpose of this arrangement is that the gasket 6 is used to fix the lower connecting column 5 to the bottom of the motorcycle bracket, and at the same time, the height of the rear shock absorber body 1 can be extended.

[0029] Preferably, the inner rotation of the gasket 6 is connected with the support piece 8, and an angle is set between the gasket 6 and the support piece 8, and the first rotating plate 301, the second rotating plate 302, the gasket 6 and the support piece 8 are made of rigid metal materials. The purpose of this arrangement is that the support piece 8 has a supporting effect on the gasket 6, and enhances the stability of the connection between the bottom of the rear shock absorber body 1 and the motorcycle frame. The first rotating plate 301, the second rotating plate 302, the gasket 6 and the support piece 8 made of rigid materials enhance the strength of the parts, and prevent the parts from being bent and damaged during the driving of the motorcycle, which affects the driving safety of the vehicle.

[0030] In this embodiment, after the upper connecting column 2 at the top of the rear shock absorber body 1 is installed at the connection between the first rotating plate 301 and the second rotating plate 302, the lower connecting column 5 of the rear shock absorber body 1 is connected to the bottom frame of the motorcycle using the gasket 6, thereby increasing the length of the rear shock absorber body 1 while enhancing the stability and strength of the rear shock absorber body 1, thereby preventing the motorcycle from being damaged during driving and affecting the safety of the motorcycle during operation.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
