Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber and a vehicle that can be disassembled and adjusted repeatedly. Background Art

[0002] The valve system of the shock absorber plays a vital role in the shock absorber. The reasons that affect the force value of the valve system during the use of the shock absorber are also very complicated, and there are many influencing factors: materials, combinations, cleanliness, design and manufacturing, and assembly quality, etc. There are currently two ways to package the shock absorber. In the old-fashioned flanging structure, the guide needs to cooperate with the working cylinder, and the valve system can be freely disassembled during the adjustment process to achieve repeated adjustment. The guide and the liquid storage cylinder of the single-tube structure are assembled by riveting. Once the valve system force value does not reach the ideal state after riveting, it needs to be re-adjusted. Only a new liquid storage cylinder assembly can be selected for adjustment. This process will cause waste of manpower and material resources. Therefore, a removable shock absorber debugging structure is urgently needed to solve the current dilemma. In view of the above-mentioned defects, this application is proposed. Utility Model Content

[0005] According to an embodiment of the utility model, a side of the push block used for tightening the guide is provided with a boss whose diameter is smaller than the inner diameter of the outer tube of the shock absorber.

[0006] According to an embodiment of the present invention, the maximum diameter of the top block is the same as the maximum inner diameter of the sleeve.

[0007] According to an embodiment of the utility model, the outer end surface of the top block is flush with the end of the sleeve.

[0019] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0020] [Example 1]

[0021] A removable and adjustable shock absorber, such as Figure 1, including a shock absorber outer tube 1 and a connector assembly 2, the shock absorber outer tube 1 is provided with an external thread 11, the connector assembly 2 includes a sleeve 22 and a top block 21, the sleeve 22 is provided with an internal thread 23, the shock absorber outer tube 1 is screwed into the sleeve 22 to achieve connection, the top block 21 is connected to the sleeve 22, the top block is used to tighten the guide, and the top block 21 is provided with a through hole 24 for the piston rod to extend.

[0022] The solution is to first process an external thread on the outer tube of the shock absorber's liquid storage cylinder, i.e., the shock absorber outer cylinder 1, and then process a sleeve that matches the thread and press a top block on the sleeve, position the top block and the sleeve and weld them together to form an assembly, and during debugging, screw in the welded assembly to a specified height and debug the valve system. After this debugging is completed, the assembly is reversely screwed out and the single result is evaluated, and then the debugging is repeated. The original riveting process is replaced by a threaded connection structure, and the product can be freely disassembled and the valve system force value can be repeatedly adjusted during valve system adjustment, which improves the disadvantage that the original structure cannot be repeatedly adjusted, can save resource waste caused by debugging the valve system, and allows the liquid storage cylinder to be reused during the debugging process, greatly improving efficiency and saving company resources.

[0023] Preferably, a boss 26 having a diameter smaller than the inner diameter of the shock absorber outer tube 1 is provided on one side of the top block 21 for tightening the guide. On the one hand, the guide assembly 3 can be tightened by the boss 26, and the tightening force can be better adjusted. On the other hand, Figure 2 As shown, a larger space margin can be reserved for the shock absorber outer tube 1, which is convenient for adjustment and avoids deformation caused by the edge of the shock absorber outer tube 1 and the top block 21.

[0024] Furthermore, the maximum diameter of the top block 21 is the same as the maximum inner diameter of the sleeve 22, so that the top block 21 can be embedded in the sleeve 22, and the outer end surface of the top block 21 is flush with the end of the sleeve 22, ensuring that the overall length is controlled within a certain range.

[0025] In this embodiment, the sleeve 22 and the top block 21 are connected by welding. Figure 2 , Figure 4 In order to ensure the strong welding effect and aesthetics, chamfers 25 are provided at the welding positions of the sleeve 22 and the top block 21, leaving a welding area after assembly.

[0026] In this embodiment, the length of the internal thread 23 area should be greater than half of the overall length of the sleeve 22. For example, the length of the sleeve 22 is 40 mm, and the length of the internal thread 23 area is 25 mm, to ensure the connection length of the thread between the sleeve and the outer tube of the shock absorber, thereby ensuring the firmness.

[0027] Preferably, if Figure 4The wall thickness of the sleeve 22 in the area where the internal thread 23 is provided is greater than the wall thickness of other areas, which ensures the strength of the sleeve while reducing the weight of the sleeve, thereby reducing the overall quality of the product.

[0028] A vehicle comprises the above-mentioned removable and adjustable shock absorber.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed and modified in any way.
