Description

[0002] like Figure 5 and Figure 6 As shown, the existing shock absorber bushing structure includes an inner lining pipe 9, a rubber lining kit 10 and an outer lining pipe 11 structure which are sequentially sleeved. The inner lining pipe 9 and the outer lining pipe 11 are concentric. The rubber lining kit 10 adopts a vulcanization process to connect the inner lining pipe 9 and the outer lining pipe 11 together. Taking the bushing structure at the bottom end of the shock absorber 8 as a reference, the shock absorber 8 swings back and forth around the axis of the bushing structure at the bottom end. At this time, the inner lining pipe 9 and the outer lining pipe 11 produce relative rotation, and the relative rotation amount between the inner lining pipe 9 and the outer lining pipe 11 is achieved by the deformation of the rubber lining kit 10. This structure is simple and low in cost. However, the rotation angle of the existing shock absorber bushing structure during operation is achieved by the deformation of the rubber lining kit. Due to the deformation of the rubber material, when the working angle is too large, the rubber lining kit is greatly deformed, which is prone to the quality problem of the rubber lining kit being torn, and the service life of the bushing structure is reduced, which cannot meet the layout and design requirements.

Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0028] like Figure 2-Figure 4 As shown, the utility model provides a shock absorber bushing structure, which is used to be connected to the top or bottom end of the shock absorber 8. The bushing structure includes an outer bushing 1 and an inner bushing 2. The outer bushing 1 is sleeved on the outside of the inner bushing 2. The outer bushing 1 and the inner bushing 2 are relatively rotatably connected, and an elastic layer 3 is provided between the outer bushing 1 and the inner bushing 2.

[0029] Specifically, in order to solve the problem that the rubber lining kit of the existing shock absorber bushing structure adopts a vulcanization process to connect the inner lining pipe and the outer lining pipe together, during operation, the turning angle is achieved by the deformation of the rubber lining kit. Due to the deformation of the rubber material, when the working angle is too large, the rubber lining kit is greatly deformed, and the rubber lining kit is easily torn, the service life of the bushing structure is reduced, and the layout and design requirements cannot be met, the utility model provides a shock absorber bushing structure, the outer bushing 1 and the inner bushing 2 of the bushing structure are relatively rotatably connected, and an elastic layer 3 is provided between the outer bushing 1 and the inner bushing 2, eliminating the problem that the torsion between the inner lining pipe and the outer lining pipe of the existing shock absorber bushing structure is limited by the deformation of the rubber material, and free rotation is achieved. At the same time, under the action of the elastic layer 3, the bushing structure has a certain shock absorbing function, avoiding the failure problem caused by the deformation of the rubber material during the use of the bushing structure, and improving the service life of the bushing structure.

[0030] Preferably, at least one inner nested component is arranged between the elastic layer 3 and the inner liner 2, and there are two inner nested components, which are respectively a first inner nested component 4 and a second inner nested component 5. The first inner nested component 4 and the second inner nested component 5 are respectively sleeved on the inner side of the elastic layer 3 and the outer side of the inner liner 2, and the first inner nested component 4 and the second inner nested component 5 are relatively rotatably connected.

[0031] Specifically, taking the bushing structure at the bottom end of the shock absorber 8 as a reference, when the shock absorber 8 swings back and forth around the axis of the bushing structure at the bottom end, at this time, the outer bushing 1 and the inner bushing 2 rotate relative to each other, that is, the first inner nested component 4 and the second inner nested component 5 rotate relative to each other, thereby realizing the rotation angle of the bushing structure and eliminating the torsion between the inner lining pipe and the outer lining pipe of the existing shock absorber bushing structure which is limited by the deformation of the rubber material.

[0035] Specifically, the two bosses 23 are in contact with the two gaskets 6 respectively. When the first inner nested component 4 and the second inner nested component 5 rotate relatively, the gasket 6 serves as a transition piece to prevent the two bosses 23 from directly contacting and generating friction with the second inner nested component 5.

[0036] Preferably, a slot 7 is provided on the inner side of one end of the liner pipe 2 , and one end of the liner pipe head 2 is connected to the inner side of the slot 7 by interference fit.

[0037] Specifically, one end of the liner pipe head 2 is connected to one end of the liner pipe 2 by an interference fit connection method, so as to avoid the two bosses 23 restricting the installation of the liner sleeve 2 and the second inner nested component 5.

[0038] Preferably, the elastic layer 3 is a rubber set, and the outer bushing 1, the elastic layer 3 and the first inner nested component 4 are connected in sequence by vulcanization.

At the same time, the swing and radial performance of the bushing structure will not be affected.
