Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To effectively illustrate the embodiments of this utility model, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] See Figure 1 The diagram shows a related embodiment of a transverse shock absorber compression valve assembly. The transverse shock absorber compression valve assembly includes a compression valve assembly 3, which is transversely installed between the working cylinder 1 and the oil reservoir base 5. The compression valve assembly 3 is positioned circumferentially with the oil reservoir 2 by a centering shim 4. The compression valve assembly 3 is provided with a compensation valve oil passage 35a. During the operation of the shock absorber, when the return stroke is completed, the oil in the oil reservoir 2 enters the working cylinder 1 through the compensation valve oil passage 35a to achieve oil exchange.

[0025] For specific implementation details, please refer to Figure 2 The exploded structural diagram of the compression valve assembly 3 shown is thus combined with Figure 1 This application provides a detailed description of the lateral damper compression valve assembly disclosed in this application. Figure 2 As shown, the compression valve assembly 3 includes a compression valve screw 31 arranged laterally, a compression valve seat 35 and a compression valve nut 40. The lower part of the compression valve seat 35 is provided with a compensation valve oil passage 35a. Through the compensation valve oil passage 35a on the compression valve seat 35, the oil in the oil storage cylinder 2 enters the working cylinder 1 to achieve oil exchange.

[0026] Of course, combined Figure 2As shown, the compression valve screw 31 should pass through the compression valve seat 35 and connect to the compression valve nut 40. However, in order to ensure the function of the compression valve assembly 3, a compensation valve limiter 32, a compensation valve spring 33, and a compensation valve plate 34 are also arranged sequentially between the compression valve screw 31 and the compression valve seat 35. A compression valve washer 36, a compression valve plate 37, a compression valve spring seat 38, and a compression valve spring 39 are also arranged sequentially between the compression valve seat 35 and the compression valve nut 40. Of course, although the compression valve screw 31, compensation valve limiter 32, compensation valve spring 33, compensation valve plate 34, compression valve seat 35, compression valve washer 36, compression valve plate 37, compression valve spring seat 38, compression valve spring 39, and compression valve nut 40 shown in the figure are arranged from top to bottom, in the transverse vibration damper they should be arranged transversely from left to right, so as to realize the transverse placement of the compression valve assembly 3.

[0027] In specific implementation, the compensating valve oil circuit 35a includes multiple compensating valve channels 35b, which are asymmetrically distributed on the compression valve seat 35, such as... Figure 3 As shown, the multiple compensation valve channels 35b are evenly distributed in a fan shape on the compression valve seat 35, and the fan angle is 120 degrees, that is, as Figure 3 As shown, the compression valve seat 35 is provided with five compensation valve channels 35b, and the centers of these five compensation valve channels 35b are designed at 120 degrees. During the actual installation process, after the compression valve assembly 3 is installed in place, it is necessary to ensure that all compensation valve channels 35b are located below the laterally positioned compression valve assembly 3. Since air is less dense than oil, it will accumulate at the top of the oil reservoir. The compensation valve channels 35b being located below prevent air from entering the working cylinder 1 from the oil reservoir 2 through the compensation valve channels 35b, effectively avoiding functional defects in the lateral vibration damper and thus improving its working performance.

[0028] In the specific implementation process, you can also refer to Figure 4 and Figure 5 The schematic cross-sectional view of the centering pad and the lateral damper compression valve assembly shown is used to illustrate the above-described embodiments. Figure 4 As shown, the centering gasket 4 is a circular gasket structure, and the outer periphery of the circular gasket is provided with a flange (4a). The flange (4a) of the centering gasket 4 is provided with a relief groove (4b), and the oil reservoir 2 is provided with a concave point in the middle. During the installation of the compression valve assembly 3, the concave point in the middle of the oil reservoir 2 serves as a positioning mark. The centering gasket 4 achieves circumferential positioning of the compression valve assembly 3 and the oil reservoir 2 through the relief groove (4b) and the concave point in the middle of the oil reservoir 2, and ensures that the compensation valve oil passage 35a of the compression valve assembly 3 is located at the lower part of the transverse vibration damper after installation, preventing air from the upper part of the oil reservoir 2 from entering the working cylinder 1.

[0029] Of course, in the implementation process, according to the structure of the above embodiment is installed, in the lateral damper recovery stroke, the oil in the oil tank cylinder 2 flows through the compensation valve channel 35b of the compression valve seat 35, and the compensation valve spring 33 is deformed by oil pressure, so as to push away the compensation valve piece 34; so that the oil in the oil tank cylinder 2 enters the inside of the working cylinder through the compensation valve channel 35b; at the same time, due to the asymmetric distribution of the compensation valve channel 35b of the compression valve seat 35, which is concentratedly arranged below the damper, the air will gather in the upper part of the oil tank cylinder due to the smaller density of air than oil; so as to avoid the air in the oil tank cylinder 2 entering the working cylinder 1 through the compression valve seat 35, effectively avoiding the functional defects of the lateral damper, and further improving the working performance.

[0030] Of course, in the implementation process, the structure of the damper is not limited to the above structure proposed in the application, but the specific structure disclosed in the application is the main structural component for solving the technical problems of the application, and other related structures can be referred to the description of the damper in the prior art, which will not be described in detail here.

[0031] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
