[0006] Preferably, the middle portion of the clutch cover is hollowed out.

[0007] Furthermore, the clutch friction plates include a plurality of active friction plates and a plurality of driven friction plates, and the active friction plates and driven friction plates are alternately arranged on the clutch center sleeve.

[0008] In order to ensure smooth power transmission and reduce power transmission impact, one end of the friction plate locating pin is connected to the center groove of the clutch center sleeve, and the other end is connected to the center groove of the clutch pressure plate, with the center groove formed by the semicircular groove of the clutch center sleeve and the semicircular groove of the clutch driven friction plate passing through the middle.

[0009] Preferably, the semicircular groove of the clutch driven friction plate is located on the inner diameter of the clutch driven friction plate.

[0010] In order to facilitate stable power transmission, the inner diameter of the semicircular groove on the clutch center sleeve and the clutch friction plate is the same as the inner diameter of the circular groove on the clutch center sleeve and the clutch pressure plate, and is the same as the outer diameter of the friction plate locating pin.

[0011] Preferably, a clutch release spring and a locking bolt are provided in the middle of the clutch center sleeve, and the clutch pressure plate, clutch release spring, clutch friction plate and clutch center sleeve are connected together by the locking bolt.

[0012] The utility model has the following beneficial effects:

[0013] 1. To meet the concept of "lightweight, high strength, and high load impact" for off-road motorcycles, the clutch cover has no buffer structure, the oil pump drive gear and the clutch driven gear are integrated into the clutch cover, and the middle part of the clutch cover is hollowed out to achieve the design purpose of light weight, high strength and compact structure. The friction plate positioning pin is used to achieve the tightness of the fit between the components and the smooth power transmission.

[0014] 2. The reliability of use is improved. The circular groove structure increases the force-bearing area, thereby achieving the purpose of protecting the clutch driven friction plate and the clutch center sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
