Description

Technical Field

[0001] The utility model relates to the technical field of buffer tools, in particular to a sprocket buffer body. Background Art

[0002] In order to reduce wheel hub wear and noise during driving, a buffer rubber block is usually installed at the connection between the sprocket and the hub for buffering. This method can greatly increase the service life of the hub and significantly reduce driving noise.

[0003] However, it is found during the use of commonly used buffer rubber blocks that they are prone to aging due to their material, which causes them to not fit well with the sprocket connector, thus causing the sprocket to loosen, affecting the normal use of the wheel hub and even causing the chain to break. Therefore, the buffer rubber blocks need to be replaced regularly. During the replacement process, the entire wheel needs to be removed and the parts removed one by one before the buffer rubber blocks can be replaced. The replacement process is relatively cumbersome. On the one hand, the service life of the buffer rubber blocks is reduced. On the other hand, it is difficult to restart the vehicle and use it normally in a very short time.

[0004] Therefore, it is necessary to provide a new sprocket buffer body to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0020] Please refer to Figure 1-Figure 4 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the sprocket buffer body provided by the utility model; Figure 2 This is a front view structural schematic diagram of the utility model; Figure 3 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 4 for Figure 1 The enlarged schematic diagram of part B is shown. The sprocket buffer body includes: a connecting sleeve 1, a sprocket 2 and a connecting cover 3, wherein the sprocket 2 is fixedly sleeved on the connecting sleeve 1, the connecting cover 3 is fixedly installed on one side of the connecting sleeve 1, and a through hole is opened on one side of the connecting cover 3, the through hole is connected to the connecting sleeve 1, and four mounting sleeves 4 are arranged in the connecting cover 3, and mounting plates 6 are installed in the four mounting sleeves 4 by bolts, and buffer pads 5 are fixedly installed on the four mounting plates 6, and the four buffer pads 5 extend to the outside of the connecting cover 3 away from the side of the connecting sleeve 1. When installing, the buffer pads 5 are in contact with the external buffer rubber block, so that the sprocket 2 can be buffered by the buffer rubber block. To form a buffer, four square rods 7 distributed in a ring array are slidably installed on one side of the connecting cover 3 close to the sprocket 2, and one end of the four square rods 7 located in the connecting cover 3 is fixedly connected to the four mounting sleeves 4 respectively, and a spring 8 is sleeved on the square rods 7. The spring 8 is located in the connecting cover 3, and one end of the spring 8 is fixedly connected to the mounting sleeve 4, and the other end is fixedly connected to the inner wall of the connecting cover 3 close to the sprocket 2. The ends of the four square rods 7 located outside the connecting cover 3 are fixedly installed with wedge blocks 9, and four pushing mechanisms are provided on the connecting cover 3, and the four pushing mechanisms are respectively adapted to the four wedge blocks 9.

[0021] In the above method, the proposed push mechanism includes a folding plate 10, which is fixedly installed on the outer ring wall of the connecting cover 3. A threaded rod 11 is threadedly installed on the folding plate 10, and a wedge plate 12 is rotatably installed at the bottom end of the threaded rod 11, and the wedge plate 12 is in contact with the corresponding wedge block 9. A screw head 14 is fixedly installed on the top end of the threaded rod 11, and a spring 13 is sleeved on the threaded rod 11. The top end of the spring 13 is in contact with the screw head 14, and the bottom end of the spring 13 is in contact with the folding plate 10. By twisting the screw head 14, the wedge plate 12 can be brought down, thereby squeezing the wedge block 9 and the square rod 7 as well as the mounting sleeve 4 to move horizontally. In this way, the buffer pad 5 is tightly attached to the buffer rubber block, thereby re-forming a buffering effect on the sprocket 2.

[0022] In this embodiment, when the threaded rod 11 rotates, in order to prevent the wedge plate 12 from rotating therewith, a limit rod 16 is fixedly installed on the folding plate 10, and a connecting piece 15 is slidably installed on the limit rod 16, and one side of the connecting piece 15 is fixedly connected to the wedge plate 12.

[0023] The working principle of the sprocket buffer body provided by the utility model is as follows:

[0024] When the buffer rubber block does not form contact with the connecting cover 3, in order to prevent the sprocket 2 from loosening, the corresponding screw head 14 can be rotated first, which drives the corresponding threaded rod 11 to rotate. Under the sliding limit of the limit rod 16 and the connecting piece 15, the wedge plate 12 begins to drop vertically. At this time, the sliding cooperation between it and the wedge block 9 can push the corresponding wedge block 9. The wedge block 9 pushes the square rod 7 and the corresponding mounting sleeve 4 to move horizontally, and the corresponding spring 1 8 is stretched until the corresponding buffer pad 5 is tightly attached to the buffer rubber block and stops rotating. At this time, the corresponding spring 2 13 is also compressed due to the descent of the threaded rod 11, which can provide an elastic top force to the threaded rod 11, thereby increasing the thread preload between it and the folding plate 10 to prevent rotation.

[0025] Then, the other screw heads 14 are rotated in sequence in the same manner as above, so that the other buffer pads 5 are closely attached to the corresponding buffer rubber blocks;

[0026] In subsequent use, when the buffer rubber block and the buffer pad 5 need to be repaired and replaced, the thread between the mounting plate 6 and the mounting sleeve 4 can be unscrewed, and the buffer pad 5 together with the mounting plate 6 can be taken out from the mounting sleeve 4, and then replaced with a new one.

[0027] Compared with the related art, the sprocket buffer body provided by the utility model has the following beneficial effects:

[0028] The utility model provides a sprocket buffer body. By setting four independent buffer pads 5 and slidingly cooperating with a wedge block 9 and a wedge plate 12, the position between the buffer pad 5 and the buffer rubber block can be adjusted according to the specific degree of wear of the buffer rubber block. By adjusting the positions of the two, the sprocket 2 can continue to obtain the buffer effect of the buffer rubber block without replacing the buffer rubber block, thereby increasing the service life of the buffer rubber block, correspondingly reducing the number of replacement times of the buffer rubber block, and also enabling the motorcycle to be quickly put into use.
