[0001] The utility model relates to the technical field of center sleeves, in particular to a clutch center sleeve with an oil storage function. Background Art

[0002] The motorcycle clutch center sleeve assembly is composed of a center sleeve, a pressure plate, an end cover, and a friction plate and a clutch plate between the center sleeve and the pressure plate, which are assembled by bolts and springs. The inner side of the center sleeve and the pressure plate are in contact with the annular surface of the friction plate in the middle. The center sleeve is an important part of the motorcycle clutch. When the clutch is working, the power is output through the internal splines on the center sleeve. Therefore, the internal spline structure of the center sleeve has a great influence on the service life and performance of the clutch.

[0003] At present, most of the clutch center sleeves on the market have been modified to prevent fracture, but the friction end face of the clutch center sleeve is in direct contact with the friction plate, and the contact point is not lubricated enough. A large amount of heat will be generated during operation, causing the friction plate temperature to be too high, thereby affecting the performance and service life of the friction plate, and abnormal noise will occur when the clutch is engaged. Therefore, a clutch center sleeve with an oil storage function is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a clutch center sleeve with an oil storage function, which has the advantages of preventing abnormal noise and convenient heat dissipation, and solves the problem that the friction end face of the clutch center sleeve is in direct contact with the friction plate, the contact point is not sufficiently lubricated, a large amount of heat is generated during operation, and the temperature of the friction plate is too high, thereby affecting the performance and service life of the friction plate, and abnormal noise occurs when the clutch is engaged.

[0005] In order to achieve the above-mentioned purpose of preventing abnormal noise and facilitating heat dissipation, the utility model provides the following technical solutions: a clutch center sleeve with oil storage function, comprising a center sleeve, a spline sleeve is arranged inside the center sleeve, and a heat dissipation structure is arranged outside the center sleeve;

[0006] The heat dissipation structure includes heat dissipation holes, heat dissipation grooves, wear-resistant rings, oil grooves, through grooves, connecting holes, oil holes and connecting grooves. The top of the center sleeve is provided with a number of heat dissipation holes, the top of the center sleeve is provided with a number of heat dissipation grooves, the top of the center sleeve is provided with a wear-resistant ring, the interior of the wear-resistant ring is provided with a number of oil grooves, the top of the center sleeve is provided with a number of through grooves, the top of the center sleeve is provided with a number of connecting holes, the top of the center sleeve is provided with a number of oil holes, and the top of the spline sleeve is provided with a number of connecting grooves.

[0007] Furthermore, a wear-resistant groove matched with the wear-resistant ring is formed on the top of the center sleeve, and the wear-resistant ring is arranged inside the wear-resistant groove to prevent the wear-resistant ring from separating from the center sleeve.

[0008] Furthermore, the two heat dissipation holes are connected through a heat dissipation groove, thereby improving the heat dissipation effect of the heat dissipation holes.

[0009] Furthermore, the oil holes and the connecting holes are distributed at equal intervals along the circumference on the top of the center sleeve, so that the multiple oil holes can dissipate heat to the center sleeve evenly.

[0010] Furthermore, the heat dissipation holes and heat dissipation grooves are distributed at equal intervals along the circumference on the top of the central sleeve, so that the heat dissipation holes can dissipate heat to the central sleeve evenly.

[0011] Furthermore, an oil circuit is provided inside the center sleeve, and a plurality of the oil holes are connected through the oil circuit, so that the oil in the plurality of oil holes can be easily heat exchanged.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The clutch center sleeve with oil storage function is provided with a heat dissipation structure. When the clutch is working, the friction between the friction plate and the wear-resistant ring generates heat, and the oil in the oil groove takes away the heat. When the clutch is converted from a disengaged state to an engaged state, since the inside of the oil hole is filled with engine oil, the excess engine oil between the friction surface and the friction plate must be discharged at the moment of engagement, forming a buffer process, thereby overcoming the abnormal noise during engagement, prolonging the service life by heat dissipation, and preventing the generation of abnormal noise.
