Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle clutch accessories, and in particular to a motorcycle clutch cover structure. Background Technology

[0002] The motorcycle clutch cover is a protective component that covers the clutch assembly. It is usually made of aluminum alloy or high-strength engineering plastic and is located as part of the engine side cover. Its main function is to prevent dust and mud from entering the clutch, reduce the impact of the external environment on critical components such as the clutch discs and springs, and provide some heat dissipation to ensure the clutch operates normally under high temperature and high load conditions. To improve the heat dissipation capacity of the clutch cover, some motorcycle clutch covers have additional integrated cooling fins.

[0003] In the existing technology, mud and dirt accumulate in the gaps between multiple heat dissipation fins after a motorcycle travels on muddy roads. However, the heat dissipation fins on the side of the motorcycle clutch cover are generally welded to the clutch cover, and the gaps between adjacent heat dissipation fins are generally small. Workers need to use brushes to reach into multiple gaps and clean them one by one, which makes the cleaning process of multiple heat dissipation fins too time-consuming and tedious. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, mud and dirt accumulate in the gaps between multiple heat dissipation fins after a motorcycle travels on muddy roads. However, the heat dissipation fins on the side of the motorcycle clutch cover are generally welded to the clutch cover, and the gaps between adjacent heat dissipation fins are generally small. Workers need to use brushes to reach into multiple gaps to clean them one by one, which makes the cleaning process of multiple heat dissipation fins too time-consuming and tedious. Therefore, this invention proposes a motorcycle clutch cover structure.

[0007] The docking ring has a circular array of heat dissipation fins inserted into its side. The heat dissipation fins are fixedly provided with limit blocks inside the docking ring. The docking ring is provided with an annular airbag inside. A control valve is fixedly provided on the side of the annular airbag and extends from the inner wall of the docking ring.

[0008] Optionally, the docking and fixing assembly includes a U-shaped rod, a central cylinder, and a central bolt. The two ends of the U-shaped rod are fixedly connected to the side of the sealing cover, and the central cylinder is welded to the side of the clutch cover.

[0009] Optionally, the central cylinder is symmetrically fixed with docking posts on its side, and the U-shaped rod is symmetrically provided with docking holes in the middle position, and the docking posts are movably inserted into the docking holes.

[0010] Optionally, a central bolt is movably inserted at the center of the side of the U-shaped rod, and the end of the central bolt is threaded into the side of the central cylinder.

[0011] Optionally, there is a gap between the inner cavity of the docking ring and the annular airbag, and the space between the inner cavity of the docking ring and the annular airbag is hollowly filled with cooling oil.

[0012] Optionally, a sealing ring is fixedly provided on the side of the docking ring, and a receiving groove is provided on the side of the clutch cover, wherein the cross-sectional dimensions of the sealing ring are the same as those of the receiving groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A motorcycle clutch cover structure includes a clutch cover body 1, heat dissipation fins 3, and a docking ring 4. A sealing cover 41 is fixedly installed on the side of the docking ring 4. A docking fixing component is installed on the side of the sealing cover 41. The docking fixing component can quickly fix the docking ring 4 to the side of the clutch cover body 1. A drain valve 2 is fixedly installed on the side of the docking ring 4. The drain valve 2 is a common on / off valve, which facilitates the replenishment and release of cooling oil inside the cavity formed by the docking ring 4 and the sealing cover 41.

[0022] The docking ring 4 has a circular array of heat dissipation fins 3 inserted into it. The heat dissipation fins 3 are fixedly provided with limit blocks 31 inside the docking ring 4. The docking ring 4 has an annular airbag 11 inside it. The annular airbag 11 has a control valve 12 fixedly provided on its side. The control valve 12 extends from the inner wall of the docking ring 4. The width of the limit block 31 is greater than the width of the heat dissipation fins 3. When the annular airbag 11 is inflated, it will push the heat dissipation fins 3 out through multiple limit blocks 31.

[0023] The docking and fixing assembly includes a U-shaped rod 7, a central cylinder 8, and a central bolt 9. The two ends of the U-shaped rod 7 are fixedly connected to the side of the closed cover 41. The central cylinder 8 is welded to the side of the clutch housing 1. Dating posts 81 are symmetrically fixed on the side of the central cylinder 8. Dating holes 10 are symmetrically opened in the middle of the U-shaped rod 7. The docking posts 81 are movably inserted into the docking holes 10. The docking posts 81 and the docking holes 10 facilitate the quick docking of the U-shaped rod 7 with the central cylinder 8.

[0024] A center bolt 9 is movably inserted into the center position of the side of the U-shaped rod 7. The end of the center bolt 9 is threaded into the side of the center cylinder 8. There is a gap between the inner cavity of the docking ring 4 and the annular air bladder 11. Cooling oil is hollowly filled between the inner cavity of the docking ring 4 and the annular air bladder 11. The cooling oil transfers the heat from the surface of the clutch cover 1 to multiple heat dissipation fins 3. A sealing ring 6 is fixedly installed on the side of the docking ring 4. A receiving groove 5 is opened on the side of the clutch cover 1. The cross-sectional dimensions of the sealing ring 6 are the same as those of the receiving groove 5. The sealing ring 6 improves the sealing performance between the clutch cover 1 and the docking ring 4.

[0025] The specific implementation steps and principles of this utility model are as follows:

[0026] When multiple heat dissipation fins 3 are working, the annular airbag 11 is in an inflated state, and the multiple heat dissipation fins 3 are pushed out by the limiting block 31. The heat dissipation fins 3 carry away the heat of the clutch cover 1 through the docking ring 4 and the cooling oil inside the docking ring 4.

[0027] When it is necessary to clean the mud between multiple heat dissipation fins 3, open the control valve 12 and manually press the multiple heat dissipation fins 3 into the docking ring 4 to expose the mud.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
