[0024] like Figures 1 to 6As shown, a disc brake housing for a motorcycle comprises a first housing 1 and a second housing 2, a first placement hole 101 is provided in the middle of the first housing 1, a first mounting hole 105 is provided on the first housing 1, a guide column 5 is arranged in the first mounting hole 105, the first placement hole 101 is used to place a motorcycle disc brake pad, one end of the disc brake pad is slidably connected to the guide column 5, so that the disc brake pad slides and clamps the brake disc for braking, a second placement hole 201 is provided in the middle of the second housing 2, the second placement hole 201 is arranged opposite to the first placement hole 101, a second mounting hole 206 is provided on the second housing 2, a conduit 8 is arranged in the second mounting hole 206, one end of the guide column 5 is slidably arranged in the conduit 8, and the two cooperate to play a guiding role to prevent the first housing 1 and the second housing 2 from offsetting during the locking process, the second placement hole 201 is used to place another disc brake pad, one end of the disc brake pad is slidably connected to the conduit 8.

[0025] like Figures 3 to 5 As shown, a first groove 102 is provided on the surface of the first shell 1, and two threaded holes 106 are provided on the surface of the first shell 1, one of which is located above the first groove 102. A connecting hole 107 is provided on the surface of the first shell 1, and a second placement groove 109 is provided at the bottom of the connecting hole 107. A positioning pin 6 is slidably arranged in the connecting hole 107, and a second spring 7 is arranged between the bottom of the positioning pin 6 and the bottom of the second placement groove 109. A groove 202 is provided on the surface of the second shell 2, and the shape of the groove 202 is adapted to the shape of the first groove 102. A third placement groove 204 is arranged at the bottom of the groove 202, and the third placement groove 204 is arranged opposite to the connecting hole 107. One end of the positioning pin 6 is arranged in the third placement groove 204, and the positioning pin 6 plays a positioning role when locking the shell.

[0026] like Figure 5 and Figure 6As shown, a slide groove 103 is provided on the surface of the first shell 1, and four first placement grooves 108 are evenly provided at the middle position of the bottom of the slide groove 103. A second groove 104 is provided on the inner wall of the slide groove 103. A connecting rubber ring 3 is slidably provided in the slide groove 103. A sliding hole 31 is provided in the connecting rubber ring 3. A slider 32 is provided on the inner wall of the sliding hole 31. The cross-sectional shape of the slider 32 is adapted to the shape of the second groove 104, and plays a limiting role when the connecting rubber ring 3 slides. Four fourth placement grooves 33 are evenly provided on the surface of the connecting rubber ring 3, and four fourth placement grooves 33 are provided between the bottom of the four first placement grooves 108. There is a first spring 4, and a convex ring 205 is arranged on the surface of the second shell 2. The shape of the convex ring 205 is adapted to the shape of the slide groove 103, so that the convex ring 205 can penetrate into the slide groove 103 to press the connecting rubber ring 3. When the bottom of the connecting rubber ring 3 is in contact with the bottom of the slide groove 103, there is a little distance between the connecting surfaces of the first shell 1 and the second shell 2, which can facilitate the subsequent adjustment of the distance between the two. When the disc brake pads are worn, the distance between the two disc brake pads is changed, so that the wheel disc can be re-locked to achieve braking. Two locking holes 203 are arranged on the surface of the second shell 2, and the two locking holes 203 are respectively located in the groove 202 and the convex ring 205.

[0027] The specific implementation method is as follows: when installing the first shell 1 and the second shell 2, the third placement groove 204 of the second shell 2 is aligned with the positioning pin 6 to facilitate installation and locking, and the guide column 5 is inserted into the hole of the guide tube 8 for further limiting to prevent the inconsistent tightening force on both sides when locking the shell and causing jamming. The connecting rubber ring 3 is lifted up and slides in the slide groove 103 by the first spring 4, and the convex ring 205 of the second shell 2 is inserted in the slide groove 103 and fits with the connecting rubber ring 3. The locking screw passes through the locking hole 203 of the second shell 2 and is screwed into the threaded hole 106. The locking screw is rotated to make the convex ring 205 press the connecting rubber ring 3 to slide. Since the bottom of the connecting rubber ring 3 abuts When at the bottom of the slide groove 103, the surface of the second shell 2 is still a certain distance from the surface of the first shell 1. When the disc brake pads arranged in the first shell 1 and the disc brake pads arranged in the second shell 2 are worn out after long-term use, they cannot hold the motorcycle wheel tightly. At this time, the locking screw can be adjusted, and the convex ring 205 continues to squeeze the connecting rubber ring 3 to deform it, so that the distance between the surfaces of the first shell 1 and the second shell 2 is reduced, and then the distance between the two disc brake pads is adjusted, so that the two disc brake pads can hold the motorcycle brake disc again without directly replacing new disc brake pads, thereby extending the service life of the disc brake pads and saving costs.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
