Therefore, in order to solve the above technical defects, we have proposed an aluminum alloy motorcycle disc brake with good shock resistance. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0024] Reference Figure 1-6 , an aluminum alloy motorcycle disc brake with good shock resistance, includes a mounting ring 1, a brake pad 2 is installed in the middle of the outer ring surface of the mounting ring 1, a protective cover 3 is provided on the outside of the front side of the brake pad 2, an air inlet is provided in the middle of the front side of the protective cover 3 and an air guide frame 4 is provided in the air inlet, both ends of the front side of the protective cover 3 are hinged with adjustment covers 5, the two sides of the adjustment cover 5 away from the hinge are attached to the outer wall of the protective cover 3, a fixing plate 6 is provided on the back side of the adjustment cover 5, and the two ends of the front side of the protective cover 3 are provided with matching mounting plates 7 corresponding to the fixing plates 6, and the mounting plates 7 are connected to the adjacent fixing plates 6 through fixing pins 8. Example

[0025] Reference Figure 1-6 , while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is:

[0026] The protective cover 3 is provided with a plurality of air vents on both sides of the cover body, and the diameter of the air vents is less than 1 cm. The setting of the air vents allows the motorcycle to not only take in air from the front side of the protective cover 3, but also blow the wind from the side of the protective cover 3 to the brake pad 2 when the outside wind blows horizontally, thereby not reducing the heat dissipation effect of the brake pad 2. At the same time, the method of limiting the diameter of the air vents also prevents gravel and the like stirred up by the front vehicle from directly hitting the surface of the brake pad 2, that is, it has a certain degree of anti-collision effect on the brake pad 2; the inner side of the protective cover 3 is provided with a filter 9, the mesh size of the filter 9 is less than 0.5 cm, and the filter 9 is installed on the inner side of the protective cover 3 by pasting. The thickness of the filter 9 is 0.2 cm. The setting of the filter 9 prevents the mud and sand stirred up by the front vehicle from directly hitting the surface of the brake pad 2, that is, on the one hand, it improves the anti-collision protection effect of the brake pad 2, and also avoids the phenomenon that mud and sand accumulate on the surface of the brake pad 2 and cause abnormal wear speed of the brake pad 2, that is, it avoids the phenomenon that the service life of the brake pad 2 is abnormally attenuated.

[0027] Mounting brackets 10 are provided at both ends of the protective cover 3. Bolt holes are provided at one end of the mounting bracket 10 away from the protective cover 3. The provision of the mounting bracket 10 enables the protective cover 3 to be connected to the frame of the motorcycle outside, thereby improving the stability of the protective cover 3. Plane bearings 11 are provided on both sides of the mounting ring 1. The inner part of the side of the protective cover 3 away from the air guide frame 4 is connected to the mounting ring 1 through the plane bearing 11. The provision of the plane bearing 11 enables the protective cover 3 to support the mounting ring 1, that is, the mounting ring 1 is not only fastened by the bolts, but also has a strong support effect on the mounting ring 1. In addition, the protective cover 3 also provides a limiting support effect, which means that the mounting ring 1 will not loosen easily when the motorcycle is bumpy outside, thereby making the brake disc have a certain degree of shock resistance; there is a gap of more than 0.5 cm between the inner wall of the protective cover 3 and the brake pad 2, and a number of inclined air guide plates are provided on the inner side of the air guide frame 4. The sheet frame on the inner side of the air guide frame 4 allows the oncoming air to be guided along the frame to the brake pad 2, thereby increasing the amount of air flowing through the brake pad 2, and further improving the heat dissipation effect of the brake pad 2.

[0028] Principle of use and advantages: During use of the utility model, the brake pad 2 is installed on the shaft of the external motorcycle tire through the mounting ring 1, and one side of the protective cover 3 is installed on the frame of the motorcycle through the mounting frame 10, and the other side of the protective cover 3 is connected to the mounting ring 1 through the plane bearing 11, so that the mounting ring for mounting the brake pad 2 is not only fastened by its own bolts, but also additionally limited and supported by the protective cover 3. Therefore, when the motorcycle vibrates, it is necessary not only to overcome the fastening of the mounting ring 1 by the bolts, but also to overcome the support of the protective cover 3 on the mounting ring 1, thereby making the mounting ring 1 have better shock resistance, that is, the brake pad 2 has better shock resistance.

[0029] At the same time, in the above process, since the two ends of the protective cover 3 are provided with rotatable adjusting covers 5, when the motorcycle is traveling in a low-speed environment where the motorcycle needs to brake frequently, the personnel can unfold the adjusting cover 5 in advance, thereby expanding the space at the air inlet of the protective cover 3 through the unfolded adjusting cover 5, thereby making the amount of air passing through the inner side of the protective cover 3, i.e., the brake pad 2, larger, thereby improving the heat dissipation effect of the brake pad 2; and due to the arrangement of the protective cover 3 and the air guide frame 4, the outer side of the brake pad 2 is provided with a grid-shaped protective frame body, so that hard objects accidentally flying from the outside cannot directly hit the surface of the brake pad 2, i.e., avoiding the phenomenon of the brake pad 2 being damaged by impact; in summary, this scheme, through the mutual cooperation of various components, makes it possible for the brake disc to be used, through the protective cover 3, not only to enhance the shock resistance of the brake pad 2, but also to improve the heat dissipation effect played on the brake pad 2, and at the same time, to provide anti-collision protection for the brake pad 2, thereby effectively improving the safety of the brake pad 2 when in use.

[0030] It should be further explained that the setting of the air vents allows the motorcycle to not only take in air from the front side of the protective cover 3 when it is running, but also allows the wind to blow from the sides of the protective cover 3 to the brake pads 2 when the outside wind blows laterally, thereby not reducing the heat dissipation effect of the brake pads 2. At the same time, the method of limiting the diameter of the air vents also prevents gravel and the like stirred up by the front vehicle from directly hitting the surface of the brake pads 2, thereby providing a certain degree of anti-collision effect on the brake pads 2; the setting of the protective filter 9 prevents the mud and sand stirred up by the front vehicle from directly hitting the surface of the brake pads 2, thereby improving the anti-collision protection effect of the brake pads 2 and avoiding the abnormal wear rate of the brake pads 2 caused by the accumulation of mud and sand on the surface of the brake pads 2. The phenomenon of abnormal attenuation of the service life of the brake pad 2 is avoided; the setting of the mounting frame 10 enables the protective cover 3 to be connected to the frame of the external motorcycle, thereby improving the stability of the protective cover 3; the setting of the plane bearing 11 enables the protective cover 3 to support the mounting ring 1, that is, in addition to the tightening effect of the bolts, the mounting ring 1 is also provided with the limiting support effect provided by the protective cover 3, that is, the mounting ring 1 will not be easily loosened when the external motorcycle is bumpy, thereby making the brake disc have a certain degree of shock resistance; the sheet frame on the inner side of the air guide frame 4 allows the oncoming air to be guided along the frame to the brake pad 2, thereby increasing the amount of air flowing through the brake pad 2, and further improving the heat dissipation effect of the brake pad 2.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
