[0026] According to this specific embodiment, the sprocket 102 is sleeved on one end of the buffer body 101, and a tooth claw 110 is provided at the end of the buffer body 101 away from the sprocket 102. A notch 111 is provided on the tooth claw 110. By providing a notch at the tooth claw 110 of the buffer body 101, it is easy to demold during die-casting, thereby improving the service life of the mold and having the characteristics of saving materials, beautiful appearance, and not affecting use.

[0027] The buffer body 101 is provided with a mounting plate 112 at one end close to the sprocket 102, and a plurality of positioning posts 113 are fixedly provided on the mounting plate 112. A plurality of fixing grooves 114 are provided on one side of the sprocket 102 close to the mounting plate 112, and each of the positioning posts 113 corresponds to one of the fixing grooves 114, and each of the positioning posts 113 is provided with a hollow structure, and the insertion rod 103 is inserted into the interior of each of the positioning posts 113, and a fixing hole 115 is provided on the side wall of each of the fixing grooves 114. A through hole 116 is provided on the side wall of each positioning column 113, and a mounting hole 117 is provided on the side of each insertion rod 103 close to the corresponding fixing hole 115. The clamping block 106 is slidably installed inside the mounting hole 117, and the spring member 105 is provided between one end of the clamping block 106 located inside the mounting hole 117 and the bottom wall of the mounting hole 117. The clamping block 106 passes through the corresponding through hole 116 and the mounting hole 117, and the insertion rod 103 is away from the clamping block 106. The clamping plate 104 is provided at one end of the sprocket 102. When installing the buffer body 101, the mounting plate 112 is clamped to the side of the sprocket 102 provided with the fixing groove 114, so that the positioning column 113 is clamped to the inside of the fixing groove 114, so that the through hole 116 is adapted to the fixing hole 115, and the plurality of insertion rods 103 are sequentially inserted into the corresponding positioning columns 113. When the insertion rods 103 are inserted into the positioning columns 113, when the holding block 106 moves to the fixing hole 115, the through hole 116 is adapted to the fixing hole 115. 5, the restoring force of the spring member 105 causes the clamping block 106 to penetrate the through hole 116 and abut against the inside of the fixing hole 115. At this time, the clamping plate 104 at one end of the insertion rod 103 located outside the mounting plate 112 covers the outside of the positioning column 113, thereby completing the installation of the mounting plate 112, and then installing the buffer body 101 on the sprocket 102. With the above structure, when installing the buffer body 101, there is no need to screw multiple bolts, and the installation is more convenient.

[0028] Secondly, the first fixing block 107 is provided at one end of the spring body 109, and the second fixing block 108 is provided at the other end of the spring body 109. The first fixing block 107 is connected to the end of the clamping block 106, and the second fixing block 108 is connected to the inner bottom of the mounting hole 117.

[0029] At the same time, a first inclined surface 118 is provided on one side of the holding block 106 close to the inner bottom of the positioning column 113, and a second inclined surface 119 is provided at the port of each positioning column 113. The first inclined surface 118 and the second inclined surface 119 are adapted to each other. Through the setting of the first inclined surface 118 and the second inclined surface 119, it is more convenient to insert the insertion rod 103 into the interior of the positioning column 113.

By providing the positioning holes 120 and the positioning protrusions 121, when the mounting plate 112 is clamped on a side of the sprocket 102 where the fixing groove 114 is provided, the structure becomes more secure.

[0031] When using a buffer body assembly for motorcycle transmission of the present embodiment, by opening a notch at the tooth claw 110 of the buffer body 101, it is easy to demould during die casting, thereby improving the service life of the mold, saving materials, having a beautiful appearance, and not affecting the use. When installing the buffer body 101, the mounting plate 112 is clamped on the side of the sprocket 102 provided with the fixing groove 114, so that the positioning column 113 is clamped on the inside of the fixing groove 114, so that the through hole 116 is adapted to the fixing hole 115, and a plurality of the insertion rods 103 are sequentially inserted into the inside of the corresponding positioning columns 113, and the insertion rods 103 are inserted into the inside of the corresponding positioning columns 113. When 103 is inserted into the interior of the positioning column 113, when the holding block 106 moves to the position corresponding to the fixing hole 115, the restoring force of the spring member 105 allows the holding block 106 to pass through the through hole 116 and then abut against the interior of the fixing hole 115. At this time, the clamping plate 104 at one end of the insertion rod 103 located outside the mounting plate 112 covers the outside of the positioning column 113, thereby completing the installation of the mounting plate 112, and then installing the buffer body 101 on the sprocket 102. With the above structure, there is no need to tighten multiple bolts when installing the buffer body 101, and the installation is more convenient.
