[0028] Example 1

[0029] In a typical implementation of the present invention, Figure 1 ,like Figure 2 , Figure 3 , Figure 4 As shown, the gearbox shock absorber disclosed in this embodiment is composed of a shell 1, a rubber ring 2, a gasket 3, a support 4 and a connecting shaft 5. A connecting shaft 5 perpendicular to the support 4 is arranged, a rubber ring 2 is sleeved on the outer ring of the connecting shaft 5, and a shell 1 is sleeved on the outer ring of the rubber ring 2. The connecting shaft 5 and the end of the rubber ring 2 are fixed by a gasket 3 and a screw 7, and a first connecting hole 6 is arranged on the shell 1.

[0030] The shell 1 in this embodiment is a cylindrical shell, and two connecting plates 1-1 are arranged on the outer ring of the shell, and first connecting holes 6 are arranged on the connecting plates 1-1; the first connecting holes 6 are used to connect the gearbox and the frame; specifically, the two connecting plates 1-1 are integrally formed or welded with the shell 1, and the two connecting plates 1-1 are symmetrically arranged on the shell 1, and two first connecting holes 6 are arranged on each connecting plate 1-1.

[0031] The support 4 in this embodiment is a rectangular block, and a connecting shaft 5 is arranged at the center of the support 4. Specifically, the support 4 and the connecting shaft 5 are welded together; and a second connecting hole 8 is also arranged on the support 4, and the second connecting hole 8 connects the support 4 and the gearbox housing. Specifically, a second connecting hole 8 is arranged on each of the four corners of the support 4, and the second connecting hole 8 realizes the connection between the support 4 and the gearbox housing.

[0032] The connecting shaft 5 in this embodiment is a solid shaft, and a hole cooperating with the screw 7 is set at its end. The gasket 3 is connected to the connecting shaft 5 through the screw 7, and the diameter of the gasket 3 is larger than the diameter of the connecting shaft 5.

[0034] The shock absorber proposed in the utility model is a circumferential shock absorber, that is, shock absorption is achieved through a cylindrical rubber ring 2, so it can play a shock absorption role in all directions, can better protect parts, and reduce wear. This kind of shock absorber occupies less space and saves space in the car.

[0035] The specific installation method is as follows;

[0036] The support 4 is connected to the case of the gearbox by bolts, and then a connecting shaft 5 is welded at the center of the support 4. The housing 1 and the rubber ring 2 are press-fitted on the connecting shaft 5 by interference fit, and then the gasket 3 is connected to the connecting shaft 5 by screws 7. The main function of the gasket 3 is to press the rubber ring 2 in the axial direction; finally, the housing 1 and the frame of the loader are connected together by bolts.

[0037] It should be further explained that, in order to better achieve shock absorption of the gearbox, the above-mentioned shock absorbers can be arranged at multiple positions of a gearbox to achieve shock absorption at multiple positions.
