Description

  The present invention relates to a motorcycle rear drive disc assembly, and in particular, the clutch block of each clutch plate is securely fitted and positioned in a dish by friction. The present invention relates to a practical rear drive disk assembly for a motorcycle without generating waste.

  Various vehicles can greatly reduce the time for transporting people or things, so it is very convenient when transporting various things in people's daily lives, making it one of the necessities for each household. . For this reason, general motorcycles are widely used because they are inexpensive and have a small occupied space, and the number is much larger than that of automobiles.

  Such a motorcycle generally has a power transmission mechanism that is connected to a drive panel, the drive panel is connected to a drive disc via a transmission belt, and the drive disk is connected to the motorcycle. When the drive panel is connected to the rear wheel and the drive panel is rotated by the power source, the drive panel rotates the drive disk via the transmission belt, and the motorcycle rotates the rear wheel of the motorcycle by the drive disk to drive the motorcycle. it can.

  Please refer to FIG. As shown in FIG. 7, a clutch plate 52 is accommodated in the dish body 51 of the drive disk 5. A plurality of pivot shafts 521 are provided on the clutch plate 52. A clutch block 522 is pivotally mounted on each pivot shaft 521. A clutch shoe 523 is disposed outside the clutch block 522. An elastic member 524 is disposed at the outer end of the clutch block 522. The clutch block 522 is kept in a contracted state toward the clutch plate 52 using the elastic member 524 so that the clutch shoe 523 of the clutch block 522 does not come into contact with the dish body 51. When the engine of the motorcycle is started, the clutch plate 52 rotates via the transmission belt as a power source, and each clutch block 522 on the clutch plate 52 is deployed outward with the pivot shaft 521 as an axis by centrifugal force. The clutch shoes 523 arranged outside the clutch blocks 522 are brought into close contact with the inner edge of the dish body 51. The dish body 51 is pushed and moved with the clutch shoe 523 being in contact therewith, and the rear wheel of the motorcycle connected to the dish body 51 is rotated in conjunction with the rotation of the clutch plate 52.

  However, the above-described drive disk can rotate the rear wheel of the motorcycle, but as it is actually used, the structure is such that the clutch shoe arranged outside the clutch block is attached to the inner edge of the plate body. When the clutch shoe is brought into close contact with the plate body and pushed to move, the clutch shoe rotates in contact with the inner edge of the plate body as the clutch plate rotates, and is generated by friction of the clutch shoe. Since the contamination may occur due to the scrap, the conventional structure has been required to be improved.

Therefore, there has been a demand for a motorcycle rear drive disk assembly that is free from the problems of the prior art.

  An object of the present invention is to provide a practical rear drive disk assembly for a motorcycle without causing scraps to be generated due to friction by securely fitting and positioning each clutch block of a clutch plate in a dish.

  In order to solve the above-described problem, according to a first aspect of the present invention, there is provided a rear drive disk assembly for a motorcycle including a dish body and a clutch plate housed in the dish body, The clutch plate has a plurality of pivot shafts. Clutch blocks are pivotally mounted on the pivot shaft, and an insertion convex portion projects from the outer side of the clutch block. A support end surface is formed at the end, and an elastic member is disposed at the outer end of the clutch block, and the clutch plate is kept in a contracted state by the clutch block using the elastic member, and the dish body The clutch plate is accommodated in the inside of the plate body, and an insertion concave tank is recessed in the inner edge of the dish body so as to correspond to the insertion convex portion of the clutch block of the clutch plate, Serial insertion concave groove is motorcycle rear drive disc assembly, characterized in that it comprises a support end surface formed to correspond to the support end surface of the fitting convex portion is provided.

  Moreover, it is preferable that the said insertion convex part is protrudingly integrated with the said clutch block.

  Moreover, it is preferable that the said insertion convex part consists of an abrasion-resistant material.

  Compared with the prior art, the rear drive disk assembly of the motorcycle of the present invention has the insertion convex portion inserted into the insertion concave tank of the dish body by the clutch block, and the support end surface of the insertion convex portion supports the support end surface of the insertion concave tank. By doing so, the insertion convex portion of the clutch block is inserted into the insertion concave tank of the dish body, the dish body rotates in conjunction with the clutch plate, and each clutch block of the clutch plate is securely inserted into the dish body and positioned. Therefore, scraps are not generated by friction, and it is practical and convenient.

This insertion convex part 121 may be integrally projected with the clutch block 12 or may be made of a wear-resistant material. A support end surface 122 is formed at the end of the insertion convex portion 121. An elastic member 13 is disposed at the outer end of the clutch block 12. The elastic member 13 is used to keep the clutch plate 1 in a contracted state by the clutch block 12.

  The dish body 2 is used to house the clutch plate 1 inside. In the inner edge of the dish body 2, an insertion concave tank 21 is recessed so as to correspond to the insertion convex portion 121 of each clutch block 12 of the clutch plate 1. The insertion concave tank 21 has a support end surface 211 formed so as to correspond to the support end surface 122 of the insertion convex portion 121.

  Please refer to FIG. 2 and FIG. As shown in FIGS. 2 and 3, when the present invention is actually assembled, the clutch plate 1 is accommodated in the dish body 2, and each clutch block 12 of the clutch plate 1 is under normal conditions by the urging force of the elastic member 13. The clutch plate 12 is kept in a contracted state so that the fitting convex portion 121 of the clutch block 12 is not brought into contact with the inner edge of the dish body 2, the clutch plate 1 and the belt wheel 3 are connected, and the belt wheel 3 is It connects with the driving wheel 4 via the belt 31 (refer FIG. 4).

  Please refer to FIG. As shown in FIG. 5, when actually using the rear drive disk assembly of the motorcycle of the present embodiment, the drive wheel 4 rotates the clutch plate 1 by the belt wheel 3 via the belt 31, Each of the clutch blocks 12 receives centrifugal force, and is developed outward with the pivot shaft 11 as an axis, and the fitting convex portion 121 protruding from the outer side of each clutch block 12 is formed on the inner edge of the dish body 2. It is made to insert in the provided insertion recessed tank 21, and the support end surface 211 of the insertion recessed tank 21 is supported by the support end surface 122 of the insertion convex part 121 (refer also to FIG. 6), and the insertion recessed tank 21 of the dish body 2 is supported. The insertion convex portion 121 of the clutch block 12 is inserted, and the dish body 2 rotates in conjunction with the clutch plate 1.

As can be seen from the above, the rear drive disk assembly of the motorcycle of the present invention has a fitting block inserted into the fitting concave tank by the clutch block, and the supporting end surface of the fitting convex portion is compared with the prior art. By supporting the support end surface of the insertion recess tank, the insertion protrusion of the clutch block is inserted into the insertion recess tank of the dish body, the dish body rotates in conjunction with the clutch plate, and each clutch block of the clutch plate is moved to the dish body. Therefore, it can be surely fitted and positioned, so that no scrap is generated due to friction, and it is practical and convenient.
