Technical Field

[0001] The utility model belongs to the technical field of motorcycle accessories and relates to a motorcycle linkage CBS valve body. Background Art

[0002] A delay valve is included in a motorcycle CBS system. At present, the sealing performance between the CBS delay valve body and the valve cover is low, which affects the use. Summary of the Invention

[0003] The purpose of the utility model is to provide a motorcycle linkage CBS valve body with improved sealing performance for the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A motorcycle linkage CBS valve body is provided with a valve cover at the top of the valve body. It is characterized in that a sealing mechanism is arranged between the valve body and the valve cover. The sealing mechanism includes a sealing gasket, a sealing transition layer and a sealing body arranged in sequence from top to bottom. The sealing mechanism is integrally formed. Both the inner and outer circles of the sealing gasket have sealing pressure-receiving parts formed by bending, and the height of the sealing pressure-receiving parts is higher than the height of the sealing gasket.

[0005] In the above-mentioned motorcycle linkage CBS valve body, a sealing groove for installing the sealing mechanism is opened at the top of the valve body. The sealing groove includes an upper sealing groove and a lower sealing groove arranged up and down. A convex part is provided on the inner wall of the valve body between the upper sealing groove and the lower sealing groove. A middle groove communicating the upper sealing groove and the lower sealing groove is provided in the middle of the convex part. The sealing body is pressed into the lower sealing groove, and the sealing transition layer is clamped into the middle groove.

[0006] In the above-mentioned motorcycle linkage CBS valve body, the sealing mechanism is made of rubber material.

[0007] Compared with the prior art, the motorcycle linkage CBS valve body of the present utility model has the advantage of high sealing performance. Brief Description of the Drawings

[0011] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model. However, the present utility model is not limited to these embodiments.

[0012] As Figure 1 , Figure 2 shown, in this motorcycle linkage CBS valve body, a valve cover 2 is provided at the top of the valve body 1. A sealing mechanism is provided between the valve body 1 and the valve cover 2. The sealing mechanism includes a sealing gasket 3, a sealing transition layer 4, and a sealing body 5 arranged in sequence from top to bottom. The sealing mechanism is integrally formed. Both the inner and outer circles of the sealing gasket 3 have sealing pressure-receiving parts 6 formed by bending. The height of the sealing pressure-receiving part 6 is higher than the height of the sealing gasket 3. After the valve cover 2 is installed, the top of the sealing pressure-receiving part 6 is pressured. Due to the bending structure of the sealing pressure-receiving part 6, a pressured space is provided. When the valve cover 2 is installed and pressured, the sealing pressure-receiving part 6 is pressured and deformed, and then closely adheres between the valve cover 2 and the valve body 1.

[0013] In further detail, a sealing groove for installing the sealing mechanism is provided at the top of the valve body 1. The sealing groove includes a sealing upper groove 7 and a sealing lower groove 8 arranged up and down. A protruding part 9 is provided on the inner wall of the valve body 1 between the sealing upper groove 7 and the sealing lower groove 8. A gap groove communicating the sealing upper groove 7 and the sealing lower groove 8 is provided in the middle of the protruding part 9. The sealing body 5 is pressured and squeezed into the sealing lower groove 8, and the sealing transition layer 4 is snapped into the gap groove to first position the sealing mechanism. By using the material characteristics of the sealing mechanism, the sealing body 5 is squeezed into the sealing lower groove 8. After positioning, the valve cover 2 is installed so that the sealing pressure-receiving part 6 is pressured and closely adheres between the valve cover 2 and the inner wall of the valve body 1.

[0014] Preferably, the sealing mechanism is made of rubber material.

[0015] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0016] Although terms such as valve body 1, valve cover 2, sealing gasket 3, sealing transition layer 4, sealing body 5, sealing pressure-receiving part 6, sealing upper groove 7, sealing lower groove 8, and protruding part 9 are used more in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
