Description

Technical Field

[0001] The utility model relates to the technical field of single disc brake brackets, in particular to a high-stability single disc brake bracket for the rear wheel of a motorcycle. Background Art

[0002] The braking system is a system that stops a motorcycle from moving, by slowing down the rotation of the wheels. Generally speaking, the brake disc made of cast iron or composite ceramic is connected to the axle and the brake pads to generate friction to stop the motorcycle.

[0003] For example, a motorcycle rear wheel single disc brake bracket with the authorization announcement number "CN216916179U" drives four sets of elastic pin assemblies to move through a rotating assembly. One end of the four sets of elastic pin assemblies slides out from the latch assembly to remove the single disc brake disc, making the disassembly and assembly of the single disc brake disc extremely simple, greatly facilitating the disassembly and assembly of the single disc brake disc by maintenance personnel. However, the device only fixes the single disc brake disc through one set of structures, and cannot guarantee the stability of the installation of the single disc brake disc. When the motorcycle brakes, it is necessary to brake through the friction between the single disc brake disc and the caliper. During braking, the single disc brake disc will be subjected to a large force. When the single disc brake disc is unstable, it will break, and the broken single disc brake disc will fly out. At the same time, the braking effect of the vehicle is reduced, which can easily cause safety accidents, resulting in reduced safety of the device. Utility Model Content

[0023] Refer to the attached Figure 1-6: The quick locking device 5 includes a transmission rod 501 and a ring 504. The surface of the transmission rod 501 is rotatably connected to the surface of the mounting column 1. The surface of the transmission rod 501 is fixedly connected with a ring 504. The ring 504 can fix the position of the transmission rod 501 so that the transmission rod 501 can only rotate and cannot move. The surface of the ring 504 is rotatably connected to the slideway opened on the inner surface of the mounting column 1 to fix the position of the ring 504. There are two protrusions 505 fixedly connected to the surface of the transmission rod 501. The protrusions 505 on both sides can push the blocks 8 on both sides to move synchronously.

[0025] Working principle:

[0026] When installing a single disc brake on the rear wheel of a motorcycle:

[0027] The first step of the fixing process:

[0028] After aligning the through holes on the surface of the single disc brake disc 10 with the multiple groups of insertion rods 4, the single disc brake disc 10 is sleeved onto the surfaces of the multiple groups of insertion rods 4, so that the single disc brake disc 10 is in contact with the surface of the bracket body 3. At the same time, the operator pulls the handle 503, so that the handle 503 can drive the transmission rod 501 to rotate synchronously through the connecting rod 502. At the same time, the transmission rod 501 will drive the torsion spring 6 to deform, so that the transmission rod 501 can drive the protrusions 505 on both sides to push the blocks 8 on both sides to move synchronously, so that the blocks 8 on both sides move out of the inside of the mounting column 1 and press against the surface of the single disc brake disc 10. After rotating the handle 503 until the through holes on the surface are aligned with the threaded holes on the surface of the mounting seat 1, pass the bolt 7 through the handle 503 and thread it into the surface of the mounting column 1, so that the angle of the transmission rod 501 is fixed, and the positions of the blocks 8 on both sides can be fixed at the same time.

[0029] The second step of fixing process:

[0030] After the operator aligns the protruding part of the surface of the shell 201 with the slide on the surface of the mounting column 1, the shell 201 is put onto the surface of the mounting column 1 and pushed so that the trapezoidal blocks 204 on both sides can engage with the grooves on the surface of the mounting column 1 to fix the position of the shell 201. At this time, the surface of the shell 201 is pressed against the blocks 8 on both sides and the surface of the single disc brake disc 10 to further fix the single disc brake disc 10.

[0031] Disassembly process:

[0032] When the single disc brake disc 10 needs to be disassembled, the operator pushes the rubber blocks 202 to both sides so that the rubber blocks 202 on both sides can drive the trapezoidal blocks 204 on both sides through the sliding rod 205 to compress the spring 203, so that the trapezoidal blocks 204 on both sides are no longer engaged with the surface of the mounting column 1, and the housing 201 can be removed. According to the above operation, the bolt 7 is removed, and the transmission rod 501 can be quickly reset under the action of the torsion spring 6, so that the protrusions 505 on both sides are no longer tightly pressed against the surfaces of the clamping blocks 8 on both sides. The operator pushes the clamping blocks 8 on both sides back into the interior of the mounting column 1 to remove the single disc brake disc 10.
