Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an adjustable double-spring motorcycle shock absorber. Background Art

[0002] The shock absorber is an important device of a motorcycle, which can filter the vibration of the road. After searching, the patent with the Chinese patent authorization announcement number of CN213954231U discloses a double spring suspension device, which belongs to the field of shock absorber technology, including a first buffer, a piston rod, a stroke adjuster and a second buffer. The first buffer is fixedly arranged at one end of the piston rod, and the other end of the piston rod is slidably inserted in the second buffer. The second buffer is connected to one end of the stroke adjuster, and the other end of the stroke adjuster is connected to the first buffer. When it is used, the first buffer and the second buffer are arranged in series. The bearing pressure generated by the vibration of the car is first absorbed by the first buffer, and then the remaining pressure is absorbed by the second buffer. The piston rod plays the role of a damper to suppress the shock from the spring rebound, and the stroke adjuster adjusts the strength of the suspension device by changing the telescopic length of the spring. The utility model has a reasonable structure and remarkable effect, and solves the problem of driver discomfort caused by insufficient shock absorption performance of the single spring shock absorber in the prior art. However, the positions of the two springs are adjusted by one adjusting device, and even if the positions of the two springs are different, the stress states are the same, so that the use effect of the double springs after adjustment is poor and the use of the device is complicated. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an adjustable double-spring motorcycle shock absorber, which solves the problem that the positions of two springs are adjusted by one adjusting device, even if the positions of the two springs are different, but the stress states are the same, thus resulting in poor use effect of the double springs after adjustment and making the use of the device complicated.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: an adjustable double-spring motorcycle shock absorber, comprising a first mounting seat, a second mounting seat and a second spring, the second mounting seat being arranged below the first mounting seat, the top fixed mounting seat of the second mounting seat having a piston cylinder, a piston rod being arranged inside the piston cylinder, the top of the piston rod being fixedly connected to the bottom of the first mounting seat, a threaded tube being fixedly sleeved on the outside of the piston cylinder, a threaded ring being threadedly sleeved on the outside of the threaded tube, a rotating ring being rotatably connected to the inside of the upper and lower side walls of the threaded ring, two second springs being arranged respectively above and below the threaded ring, the ends of the two second springs being fixedly connected to the bottom of the first mounting seat and the top of the second mounting seat respectively, and the other ends being fixedly connected to the side walls of the rotating ring inside the upper and lower sides of the threaded ring respectively.

[0005] Preferably, a first spring is provided between the first mounting seat and the second mounting seat, and upper and lower ends of the first spring are respectively fixedly connected to the bottom of the first mounting seat and the top of the second mounting seat, so that it can be used in conjunction with the second spring.

[0006] Preferably, the diameter of the rotating ring is larger than the diameter of the threaded tube, but smaller than the diameter of the threaded ring, so as to prevent the rotating ring and the threaded tube from rubbing against each other when the threaded ring rotates.

[0007] Preferably, the top of the threaded tube is lower than the top surface of the piston cylinder, and the second spring below the threaded tube is a return spring. The reset spring can prevent the threaded ring from gradually moving upward due to tension vibration during long-term use, causing the threaded ring to fall out of the side wall of the threaded tube to the outside.

[0008] The utility model provides an adjustable double-spring motorcycle shock absorber, which has the following beneficial effects:

[0009] 1. The adjustable double-spring motorcycle shock absorber, when using the adjustable double-spring motorcycle shock absorber, by placing the first spring externally and the second spring internally, the position of the second spring can be adjusted during adjustment, that is, the tensioning force of the second spring can be adjusted, and the use efficiency of the shock absorbing device body can be enhanced;

[0010] 2. When using the adjustable double-spring motorcycle shock absorber, the position of the second spring can be easily adjusted by the cooperation between the threaded ring and the rotating ring, so that the first spring and the second spring can be used together.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0016] Example 1: Please refer to Figure 1-3 The utility model embodiment provides an adjustable double-spring motorcycle shock absorber, comprising a first mounting seat 1, a second mounting seat 2 and a second spring 6, the second mounting seat 2 is arranged below the first mounting seat 1, the top of the second mounting seat 2 is fixedly mounted with a piston cylinder 8, a piston rod 9 is installed inside the piston cylinder 8, the top of the piston rod 9 is fixedly connected to the bottom of the first mounting seat 1, the outside of the piston cylinder 8 is fixedly sleeved with a threaded tube 7, the outside of the threaded tube 7 is threadedly sleeved with a threaded ring 4, the upper and lower side walls of the threaded ring 4 are rotatably connected with a rotating ring 5, two second springs 6 are provided, and are respectively arranged above and below the threaded ring 4, the ends of the two second springs 6 are respectively fixedly connected to the bottom of the first mounting seat 1 and the top of the second mounting seat 2, and the other ends are respectively fixedly connected to the side walls of the rotating ring 5 inside the upper and lower sides of the threaded ring 4, when the second spring 9 is adjusted, the threaded ring 4 is rotated so that the threaded ring 4 can move up and down outside the threaded tube 7, so that the opening degree of the second spring 9 can be adjusted.

[0017] Embodiment 2: In this embodiment, as Figure 1-3 As shown, a first spring 3 is arranged between the first mounting seat 1 and the second mounting seat 2, and the upper and lower ends of the first spring 3 are fixedly connected to the bottom of the first mounting seat 1 and the top of the second mounting seat 2 respectively, the diameter of the rotating ring 5 is larger than the diameter of the threaded tube 7 and smaller than the diameter of the threaded ring 4, the top of the threaded tube 7 is lower than the top surface of the piston cylinder 8, and the second spring 6 below the threaded tube 7 is a return spring.

[0018] It should be noted that, in this embodiment, when using an adjustable double-spring motorcycle shock absorber, Figure 1-3 As shown, when the shock absorber body is used and the spring in the shock absorber body is adjusted, the internal threaded ring 4 is rotated to make the threaded ring 4 move up and down on the outer side wall of the threaded tube 7, so that the tensioning force of the second spring 9 can be conveniently adjusted, and when the threaded ring 4 is rotated, the rotating ring 5 of the threaded ring 4 is rotated inside the threaded ring 4, which can prevent the second spring 9 from rotating with the threaded ring 4. After the adjustment is completed, the first spring 3 and the second spring 6 are used in conjunction with each other, which can enhance the use effect of the shock absorber body.
