Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, in particular to a motorcycle and a rear wheel buffer structure thereof. Background Art

[0002] Motorcycles primarily rely on the engine, belt, drive plate, and rear wheel to achieve rear wheel drive. However, during operation, the rear wheel frequently collides with rocks or speed bumps on the road. Because the drive plate and rear wheel are currently rigidly connected via bolts, the impact force exerted on the rear wheel is transmitted to the bolts. This can easily cause the bolts to break due to the combined impact and rotational force of the drive plate. Furthermore, this can cause deformation at the connection between the drive plate and rear wheel, seriously compromising the connection. Summary of the Invention

[0003] The object of the present invention is to provide a rear wheel buffer structure, which can solve the problem that the connection position between the driving disc and the rear wheel is easily damaged.

[0004] In order to achieve the above object, the technical solution of the present invention is:

[0005] A rear wheel buffer structure, comprising:

[0006] a rear wheel, a connecting plate rigidly connected to the rear wheel, and a drive plate;

[0007] The connecting disk is provided with a plurality of connecting posts protruding toward the driving disk;

[0008] The driving disk is provided with a receiving cavity matching the connecting disk, the receiving cavity is provided with a groove matching the connecting column, and the groove is provided with a buffer ring;

[0009] During installation, the inner wall of the buffer ring is in close contact with the outer wall of the connecting column, and the outer wall of the buffer ring is in close contact with the inner side wall of the groove.

[0010] The rear wheel buffer structure adopts the above-mentioned structure, which is rigidly connected to the rear wheel and the connecting plate, and the connecting plate is flexibly connected to the driving plate under the cooperation of the buffer ring, the connecting column and the groove, so that the driving plate drives the connecting plate to rotate when the driving plate rotates, and finally drives the rear wheel to rotate. The rear wheel buffer structure uses the buffer ring to buffer the impact force, instead of the direct rigid connection between the driving plate and the rear wheel in the prior art, effectively solving the problem that the connection position between the driving plate and the rear wheel is easily damaged. At the same time, the driving plate is provided with a accommodating cavity matching the connecting plate for accommodating the connecting plate, so that the rear wheel buffer structure can also be applied to the original vehicle modification. The distance between the driving plate and the rear wheel remains the same as the distance between the driving plate and the rear wheel of the original vehicle, avoiding the need to replace the corresponding motorcycle accessories and reset its parameters after the original vehicle is modified.

[0011] Furthermore, during installation, the outer wall of the buffer ring is in close contact with the inner wall of the groove, and a first distance is provided between the end surface of the connecting column and the inner end surface of the groove.

[0012] Furthermore, the first distance is 1.7 mm to 2.0 mm.

[0013] Furthermore, the plurality of connecting columns are evenly distributed on the connecting disk along the circumferential direction and are arranged close to the outer edge of the connecting disk.

[0014] Furthermore, a rear wheel mounting hole is provided on the rear wheel.

[0015] The connecting plate is provided with a connecting plate mounting hole matching the rear wheel mounting hole;

[0016] A locking bolt is tightened and matched with the connecting plate mounting hole and the rear wheel mounting hole to connect the connecting plate to the rear wheel.

[0017] Furthermore, a reserved hole matching the locking bolt is provided on one side of the driving disk close to the connecting disk.

[0018] Furthermore, the locking bolt includes a bolt head and a screw rod; during installation, the screw rod is located between the connecting plate and the rear wheel, and the bolt head is located in the reserved hole;

[0019] The reserved hole includes an inner wall of the reserved hole and an end face of the reserved hole, wherein a second distance is set between the inner wall of the reserved hole and the outer wall of the bolt head, and a third distance is set between the end face of the reserved hole and the outer end face of the bolt head.

[0020] Furthermore, a fourth distance is provided between the inner side wall of the accommodating cavity and the outer side wall of the connecting disk, and a fifth distance is provided between the inner end surface of the accommodating cavity and the outer end surface of the connecting disk.

[0021] Furthermore, the rear wheel buffer structure further comprises a rotating shaft connected to the rear wheel, and a rotating bearing is provided on the rotating shaft;

[0022] The driving disc is provided with an assembly hole matching the rotating bearing, and the assembly hole is provided with a limiting portion that abuts against the rotating bearing.

[0047] In order to fully understand the purpose, features and effects of the present invention, the concept, specific structure and technical effects of the present invention will be further described below with reference to the accompanying drawings.

[0048] like Figures 1 to 14 As shown, a rear wheel buffer structure includes:

[0049] A rear wheel 100, a connecting plate 200 rigidly connected to the rear wheel, and a driving plate 300;

[0050] The connecting disk 200 is provided with a plurality of connecting posts 230 protruding toward the driving disk;

[0051] The driving disk 300 is provided with a receiving cavity 330 matching the connecting disk, the receiving cavity is provided with a groove 310 matching the connecting column, and the groove is provided with a buffer ring 240;

[0052] During installation, the inner wall of the buffer ring 240 is in close contact with the outer wall of the connecting column 230 , and the outer wall of the buffer ring 240 is in close contact with the inner wall of the groove 310 .

[0053] The rear wheel buffer structure adopts the above-mentioned structure, which is rigidly connected to the rear wheel and the connecting plate, and the connecting plate is flexibly connected to the driving plate under the cooperation of the buffer ring, the connecting column and the groove, so that the driving plate drives the connecting plate to rotate when the driving plate rotates, and finally drives the rear wheel to rotate. The rear wheel buffer structure uses the buffer ring to buffer the impact force, instead of the direct rigid connection between the driving plate and the rear wheel in the prior art, effectively solving the problem that the connection position between the driving plate and the rear wheel is easily damaged. At the same time, the driving plate is provided with a accommodating cavity matching the connecting plate for accommodating the connecting plate, so that the rear wheel buffer structure can also be applied to the original vehicle modification. The distance between the driving plate and the rear wheel remains the same as the distance between the driving plate and the rear wheel of the original vehicle, avoiding the need to replace the corresponding motorcycle accessories and reset its parameters after the original vehicle is modified.

[0054] Preferably, the buffer ring is a rubber ring, which effectively buffers the impact force and rotational force.

[0055] Specifically, the drive plate is tightly connected to the connecting plate's connecting post via a buffer ring. Rotation of the drive plate drives the connecting plate with it. When the rear wheel collides with a rock or speed bump on the road, the buffer ring surrounds the connecting post, cushioning the impact of the connecting post and the rotational force of the drive plate. This prevents breakage of the connecting post and deformation of the connection point between the rear wheel and the connecting plate (i.e., the locking bolt).

[0056] Further, if Figure 11 As shown, a first distance α is provided between the end surface of the connecting post and the inner end surface of the groove. By setting the first distance α, direct contact between the connecting post and the groove can be prevented.

[0057] Furthermore, the first distance α is 1.7 mm to 2.0 mm.

[0058] Preferably, the first distance α is 1.7 mm.

[0059] Further, if Figure 4 and Figure 5 As shown, the plurality of connecting posts 230 are evenly distributed along the circumference of the connecting disk 200 and positioned near the outer edge of the disk. By positioning the connecting posts at the outer edge of the disk, they are positioned away from the axle, reducing the effort required by the drive disk to rotate the connecting disk. Furthermore, the connecting posts are evenly distributed along the circumference, and the distance between adjacent connecting posts remains consistent, preventing any one connecting post from being subjected to excessive rotational force.

[0060] Furthermore, a rear wheel mounting hole 110 is provided on the rear wheel 1000 .

[0061] The connecting plate 200 is provided with a connecting plate mounting hole 210 that matches the rear wheel mounting hole;

[0062] The locking bolt 230 is screwed into the connection plate mounting hole and the rear wheel mounting hole to connect the connection plate to the rear wheel.

[0063] Furthermore, if Figure 7 and Figure 8 As shown, a reserved hole 320 matching the locking bolt 220 is provided on one side of the driving disk 300 close to the connecting disk 200 . The locking bolt is arranged to avoid air through the reserved hole, so that the connecting disk can be better arranged in the accommodating cavity 330 .

[0064] Further, if Figure 14 As shown, the locking bolt 230 includes a bolt head 231 and a screw rod 232; during installation, the screw rod is located between the connecting plate and the rear wheel, and the bolt head is located in the reserved hole;

[0065] The reserved hole includes an inner wall of the reserved hole and an end face of the reserved hole, wherein a second distance d1 is provided between the inner wall of the reserved hole and the outer side wall of the bolt head, and a third distance d2 is provided between the end face of the reserved hole and the outer end face of the bolt head. By setting the second distance d1 and the third distance d3, a rigid connection caused by contact between the driving disk and the bolt head of the locking bolt can be effectively avoided, thereby ensuring that there is only a flexible connection between the driving disk and the connecting disk using the buffer ring.

[0066] Furthermore, a fourth distance d3 is provided between the inner wall of the accommodating cavity and the outer wall of the connecting disk, and a fifth distance d4 is provided between the inner end face of the accommodating cavity and the outer end face of the connecting disk. By setting the fourth distance d3 and the fifth distance d4, a rigid connection caused by direct contact between the driving disk and the outer wall and end face of the connecting disk can be effectively avoided, thereby ensuring that there is only a flexible connection between the driving disk and the connecting disk using the buffer ring.

[0067] Furthermore, if Figure 1 、 Figure 7 、 Figure 12 and Figure 13 As shown, the rear wheel buffer structure further includes a rotating shaft 400 connected to the rear wheel 100, and a rotating bearing 410 is provided on the rotating shaft 400;

[0068] The driving disk 300 is provided with an assembly hole 340 that matches the rotating bearing, and the assembly hole is provided with a limiting portion 350 that abuts against the rotating bearing 410. By abutting against the rotating bearing and the limiting portion, the movement of the driving disk in the horizontal direction can be limited to prevent the driving disk from detaching.

[0069] The rear wheel buffer structure of the present invention is flexibly connected to the connecting plate through a driving plate. When the driving plate rotates, it drives the connecting plate to rotate, thereby rotating the rear wheel. It uses a flexible connection to replace the rigid connection between the driving plate and the rear wheel in the prior art, buffering the impact force and rotational force, and effectively solving the problem of easy damage to the connection position between the driving plate and the rear wheel.

[0070] The present invention also provides a motorcycle, which includes the above-mentioned rear wheel buffer structure.
