Description

Technical Field

[0001] The utility model relates to the technical field of electric motorcycles, in particular to a wheel assembly of a motorcycle. Background Art

[0002] Motorcycle brakes are devices that can slow down, stop or keep a motorcycle stopped. They are mechanical parts that stop or slow down the moving parts of a machine. Especially for high-speed electric motorcycles, because the speed of the whole vehicle is high, a matching brake system is needed to provide it with sufficient braking force.

[0003] In the existing motorcycle braking system, the brake pump body is installed on the outer edge of the brake disc and is arranged in the wheel rim. After the brake disc is assembled to the brake pump body, due to the influence of the wheel hub size, the brake disc size and the brake caliper size, the gap between the brake pump body and the inner side of the wheel rim is too small. If the air nozzle is still arranged directly on the rim according to the conventional scheme, it will cause interference with the brake pump body or the gap will be too small, or even interfere with the brake pump body, further causing foreign debris to be easily clamped in the too small gap during the subsequent driving of the motorcycle, thereby damaging the wheel hub, the brake pump body and the air nozzle.

[0027] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0028] like Figures 1 to 3 As shown, this embodiment provides a wheel assembly for a motorcycle, the wheel assembly for the motorcycle includes: a rim 1, a wheel hub, a brake disc 2 and a brake pump body 3, the rim 1 is sleeved on the outer side of the wheel hub, the brake disc 2 is fixedly connected to the wheel hub and arranged on one side of the rim 1, the brake pump body 3 is installed on the outer edge of the brake disc 2 and arranged in the rim 1, and the wheel assembly for the motorcycle also includes an air nozzle 4, the air nozzle 4 is arranged on the inner side wall of the rim 1 and is located on the other side of the rim 1, and the air nozzle 4 is arranged to be tilted outward relative to the radial direction of the rim 1. In this way, the air nozzle 4 is installed on the inner side wall of the rim 1 to realize side mounting, and is arranged on the side opposite to the brake pump body 3 and the brake disc 2, so that the air nozzle 4 and the brake pump body 3 are reasonably avoided, and interference between the two is further avoided. It should be noted that when installing the air nozzle 4, the 5° convex peak of the rim 1 needs to be partially destroyed (not completely destroyed). At the same time, since the tail size of the air nozzle 4 is relatively large, the air nozzle 4 should be designed to reduce the exposure as much as possible.

[0029] In this embodiment, the outer diameter of the brake disc 2 is 220 mm. After the brake disc 2 is assembled to the brake pump body 3, the minimum gap distance between the brake pump body 3 and the inner side of the wheel rim 1 is 4 mm.

[0030] Optionally, see Figure 3 As shown, the radially outward deflection angle of the air nozzle 4 relative to the rim 1 is in the range of 50°-63°. For example, the angle range may be 50°, 52°, 54°, 56°, 58°, 60° or 63°, which is not further limited herein. It should be noted that the specific deflection angle is as follows: Figure 3 As shown in a in .

[0031] Optionally, the air nozzle 4 includes an air nozzle body and an air nozzle cap, the air nozzle body is provided with a through air supply passage, the air nozzle cap is sleeved on one end of the air nozzle body and is used to open or close the air supply passage.

[0032] Optionally, see Figure 1 As shown, the inner side wall of the rim 1 is provided with a step portion 5, and the other end of the valve body is connected to the step portion 5. Further, the height of the step portion 5 ranges from 12 mm to 15 mm. For example, the height of the step portion 5 can be 12 mm, 12.5 mm, 13 mm, 13.5 mm, 14 mm, 14.5 mm, or 15 mm.

[0033] Optionally, in order to lock the air nozzle 4, the wheel assembly of the motorcycle further includes a bolt 6, which is threadedly connected to the air nozzle body and abuts against the end surface of the step portion 5. It should be noted that the height of the step portion 5 is provided with a sufficient safety margin, and the step portion 5 is provided with a through hole, which penetrates the step portion 5, and the air nozzle body is threadedly connected to the bolt 6 and penetrates the through hole. At the same time, the tail of the air nozzle 4 should be as close as possible to the inner side inclined groove of the rim 1 to prevent the tail of the air nozzle 4 from being hit when the tire is installed, thereby damaging the internal components of the air nozzle 4.

[0034] Optionally, the wheel assembly of the motorcycle further includes a tire pressure monitor 7, which is mounted on the valve body. In this arrangement, the tire pressure monitor 7 is directly mounted on the valve body, making the installation of the valve body and the tire pressure monitor 7 simpler and more convenient. Furthermore, the cross section of the tire pressure monitor 7 is trapezoidal.

[0035] Optionally, in order to facilitate installation and removal of the gas valve cap, the inner surface of the gas valve cap is provided with a first thread, and the outer surface of the gas valve body is provided with a second thread, and the first thread can be connected to the second thread.

[0036] Optionally, a radian structure is provided at one end of the brake pump body 3 close to the inner side of the rim 1, and the minimum gap distance between the radian structure and the inner side of the rim 1 is not less than 10 mm. This arrangement leaves a safety margin to achieve avoidance.

[0037] Optionally, the wheel assembly of the motorcycle further includes a plurality of spokes, which are all arranged on the other side of the rim 1 and fixedly connected between the wheel hub and the rim 1 .

[0038] In this embodiment, since the weight of the air nozzle 4 equipped with the tire pressure monitor 7 is greater than that of the existing conventional air nozzle 4, especially for high-speed electric motorcycles, the larger the counterweight on one side, the larger the corresponding dynamic balance value will be, which will cause the motorcycle to shake severely during high-speed driving, and the wheel hub and the tire will need to match more dynamic balance blocks. It is necessary to remove weight at the air nozzle 4, and the rim 1 is usually only processed radially during processing due to processing costs, and cannot be milled alone. Mold inserts can be added during mold processing to balance the removed weight, achieve counterweight, achieve consistency in mass production, solve the problem of poor overall dynamic balance, and effectively alleviate the severe shaking phenomenon of high-speed electric motorcycles during driving, thereby further reducing the number of dynamic balance blocks attached in the later stage, which plays a role in reducing material costs.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
