Description

Technical Field

[0001] This utility model relates to the field of motorcycle disc brake technology, specifically a combined motorcycle disc brake. Background Technology

[0002] A motorcycle disc brake is a mechanical braking system primarily used on motorcycles. It uses brake pads to clamp onto the brake disc, generating friction to slow down or stop the vehicle. The disc brake system consists of components such as a brake cylinder, piston, and brake pads. It offers good braking performance and better heat dissipation, making it suitable for high-speed vehicles.

[0003] For example, the authorized announcement number "CN206802144U" describes an assembled motorcycle disc brake. When the disc brake is excessively worn, only the outer disc needs to be replaced, which is low-cost. It also has a wear indicator groove, which allows for a direct view of the wear level on the outer disc, enabling timely replacement of the outer disc, making it safe and reliable. However, currently, assembled motorcycle disc brakes require multiple brake discs to be tightened and fixed together with bolts. However, the bolt fixing structure of conventional motorcycle disc brakes is distributed circumferentially near the center of the disc. Since the outer and inner discs of the disc brake are fixed entirely by the squeezing force of the bolts towards the center, the locking force of the connecting bolts that are too close to the center on the outer part of the disc brake will decrease. When the outer part of the disc brake is subjected to the pressure of the motorcycle brake, a reverse force will be generated to loosen the bolts. This makes it easy for the outer disc of the disc brake to detach from the inner disc, affecting the braking effect of the motorcycle disc brake. Utility Model Content

[0004] This invention addresses the problem of reduced braking performance of existing motorcycle disc brakes by proposing a combined motorcycle disc brake.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a combined motorcycle disc brake disc, including an inner disc brake disc, an outer disc brake disc, and reinforcing cores. Two reinforcing cores are fixedly connected to the inside of the outer disc brake disc, and mounting holes are fixedly opened inside the two reinforcing cores. The inner side of the inner disc brake disc is provided with a combined stabilizing bolt fixing structure, and the outer side of the outer disc brake disc is provided with a disc brake auxiliary braking structure.

[0007] Preferably, the combined stabilizing bolt fixing structure includes positioning holes and threaded grooves. Multiple threaded grooves are fixedly opened on the inner side of the disc brake inner plate. Threaded rods are threadedly connected to the inner sides of the multiple threaded grooves. Multiple positioning holes are fixedly opened on the inner side of the reinforcing core. Locking nuts are movably connected inside the multiple positioning holes. The inner sides of the multiple locking nuts are threadedly connected to both ends of the threaded rods. Lower grooves are opened on the inner sides of the multiple positioning holes.

[0008] Preferably, the inner walls of the plurality of locking nuts abut against the outer side of the lower groove, and the plurality of positioning holes are equidistantly distributed along the outer circumference of the mounting hole.

[0009] Preferably, the disc brake auxiliary braking structure includes an anti-wear layer and insertion holes. The anti-wear layer is fixedly installed on the outer wall of the outer disc of the disc brake. A multi-layer dye plate is fixedly installed on the inner side of the anti-wear layer. Multiple insertion holes are fixedly opened on the outer wall of the inner disc of the disc brake. Multiple protrusions are movably connected to the inner side of the multiple insertion holes. Multiple heat dissipation holes are fixedly opened inside the anti-wear layer.

[0010] Preferably, the other side of the plurality of protrusions is fixedly mounted on the inner wall of the reinforcing core, and the plurality of protrusions are circumferentially distributed along the outer side of the mounting hole.

[0011] Preferably, the two outer discs of the disc brake are movably attached to the outer walls of the inner disc of the disc brake on both sides, and the mounting holes penetrate the inner side of the inner disc of the disc brake.

[0012] The present invention proposes a combined motorcycle disc brake disc, which has the following advantages: the outer disc of the disc brake is tightly fitted along both sides of the inner disc of the disc brake, and then the locking nut is inserted into the lower groove through the positioning hole and tightened at both ends of the threaded rod using a screwdriver or other tools. In this way, the outer disc of the disc brake can be firmly fixed to the outside of the inner disc of the disc brake. The locking nut and the matching threaded rod are relatively close to the outside of the motorcycle disc brake disc, and the connection between the outer and inner discs of the combined motorcycle disc brake disc is more secure, thereby improving the braking effect of the combined motorcycle disc brake disc.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1: Please refer to Figure 1-6 In this embodiment, a combined motorcycle disc brake disc includes an inner disc brake 1, an outer disc brake 2, and a reinforcing core 3. Two reinforcing cores 3 are fixedly connected inside the outer disc brake 2. The reinforcing cores 3 are made of high-strength carbon steel alloy material and are welded inside the disc-shaped outer disc brake 2, which can improve the robustness of the outer disc brake 2 that bears the braking friction of the motorcycle. The two reinforcing cores 3 are fixedly provided with mounting holes 4 inside. The mounting holes 4 are through holes that can be connected and fixed to the front end of the motorcycle at the center position. The inner side of the inner disc brake 1 is provided with a combined stabilizing bolt fixing structure 5, and the outer side of the outer disc brake 2 is provided with a disc brake auxiliary braking structure 6.

[0022] The combined stabilizing bolt fixing structure 5 includes positioning holes 51 and threaded grooves 53. Multiple threaded grooves 53 are fixedly opened on the inner side of the disc brake inner plate 1. The threaded grooves 53 are carved inside the disc brake inner plate 1. The inner side of the multiple threaded grooves 53 is threadedly connected to a threaded rod 52. The threaded rod 52 can be rotated and screwed into the inner side of the threaded groove 53. Then, the two ends of the threaded rod 52 protrude from the inner side of the disc brake outer plate 2. Multiple positioning holes 51 are fixedly opened on the inner side of the reinforcing core 3. The positioning holes 51 are used to position the locking nut 55 during installation and disassembly. The locking nut 55 is movably connected inside the multiple positioning holes 51.

[0023] The inner sides of multiple locking nuts 55 are threaded to both ends of the threaded rod 52. When installing the combined motorcycle disc brake disc, the outer disc 2 of the disc brake is tightly fitted along both sides of the inner disc 1 of the disc brake. Then, the locking nuts 55 are placed into the lower groove 54 through the positioning holes 51 and tightened at both ends of the threaded rod 52 using a screwdriver or other tools. In this way, the outer disc 2 of the disc brake can be firmly fixed to the outer side of the inner disc 1 of the disc brake. The inner sides of the multiple positioning holes 51 are provided with lower grooves 54. The inner walls of the multiple locking nuts 55 abut against the outer side of the lower groove 54. The multiple positioning holes 51 are equidistantly distributed along the outer circumference of the mounting hole 4.

[0024] The threaded groove 53 is carved inside the inner disc 1 of the disc brake. The threaded rod 52 can be rotated and screwed into the inner side of the threaded groove 53. Then, the two ends of the threaded rod 52 protrude from the inner side of the outer disc 2 of the disc brake. The positioning hole 51 is used to position the locking nut 55 during installation and removal. When installing the combined motorcycle disc brake disc, the outer disc 2 of the disc brake is tightly fitted along both sides of the inner disc 1 of the disc brake. Then, the locking nut 55 is placed into the lower groove 54 through the positioning hole 51 and tightened at both ends of the threaded rod 52 by rotating it with a screwdriver or other tools.

[0025] This allows the outer disc 2 of the disc brake to be firmly fixed to the outside of the inner disc 1. The locking nut 55 and the matching threaded rod 52 are close to the outside of the motorcycle disc brake disc, and the recessed locking nut 55 is less likely to come into contact with foreign objects and cause loosening. The connection between the outer and inner discs of the combined motorcycle disc brake disc is more secure, thereby improving the braking effect of the combined motorcycle disc brake disc.

[0026] The disc brake auxiliary braking structure 6 includes an anti-wear layer 61 and an insertion hole 64. The anti-wear layer 61 is fixedly installed on the outer wall of the disc brake outer disc 2. The anti-wear layer 61 is made of chrome-plated steel. The anti-wear layer 61 has a harder and more wear-resistant surface and better braking effect. A multi-layer dye plate 65 is fixedly installed on the inner side of the anti-wear layer 61. The multi-layer dye plate 65 is made of metal iron plates with different colors changing from the outside to the inside. The multi-layer dye plate 65 can be gradually exposed on the outside after the disc brake outer disc 2 is worn. The maintenance personnel can judge the degree of wear by the different colors exposed by the multi-layer dye plate 65.

[0027] Multiple insertion holes 64 are fixedly formed on the outer wall of the inner disc 1 of the disc brake. When the outer disc 2 and the inner disc 1 of the disc brake are installed, the insertion holes 64 can be matched with multiple protrusions 63, which reduces the alignment process when installing the inner disc 1 and the outer disc 2 of the disc brake. Multiple protrusions 63 are movably connected to the inner side of the multiple insertion holes 64. Multiple heat dissipation holes 62 are fixedly formed inside the wear-resistant layer 61.

[0028] The other side of the multiple protrusions 63 is fixedly installed on the inner wall of the reinforcing core 3. The multiple protrusions 63 are distributed equidistantly in a circle along the outer side of the mounting hole 4. The two outer discs 2 of the disc brake are movably attached to the outer sides of the inner disc 1 of the disc brake. The mounting hole 4 penetrates the inner side of the inner disc 1 of the disc brake.

[0029] Working principle:

[0030] Combination motorcycle disc brakes can be used in combination. They have outer discs on both sides that are fixed to the sides of the inner disc. The combined motorcycle disc brake is then installed on the motorcycle's braking position and connected to the brake. When the motorcycle brakes, the brake rubs against the disc brake to brake. The friction point is the outer disc of the disc brake. If the outer disc is damaged, it can be easily disassembled and replaced without replacing or repairing the inner disc of the motorcycle disc brake that plays a fixing role. This effectively reduces the operating cost of motorcycle disc brakes.

[0031] The reinforcing core 3 is made of high-strength carbon steel alloy material. The reinforcing core 3 is welded inside the disc-shaped outer disc 2, which can improve the sturdiness of the outer disc 2 that bears the braking friction of the motorcycle. The two reinforcing cores 3 are fixedly provided with mounting holes 4 inside. The mounting holes 4 are through holes that can be connected and fixed to the front end of the motorcycle at the center position.

[0032] The locking and mounting structure of the inner and outer discs of a combined motorcycle disc brake:

[0033] The threaded groove 53 is carved inside the inner disc 1 of the disc brake. The threaded rod 52 can be rotated and screwed into the inner side of the threaded groove 53. Then, the two ends of the threaded rod 52 protrude from the inner side of the outer disc 2 of the disc brake. The positioning hole 51 is used to position the locking nut 55 during installation and removal. When installing the combined motorcycle disc brake, the outer disc 2 of the disc brake is tightly fitted along both sides of the inner disc 1 of the disc brake. Then, the locking nut 55 is placed into the lower groove 54 through the positioning hole 51 and screwed into the two ends of the threaded rod 52 with a screwdriver or other tools. In this way, the outer disc 2 of the disc brake can be firmly fixed to the outside of the inner disc 1 of the disc brake.

[0034] The wear-resistant layer 61 is made of chrome-plated steel, making it more durable and wear-resistant with better braking performance. The multi-layer dye plate 65 is made of metal iron plates with different colors changing from the outside to the inside. The multi-layer dye plate 65 can be gradually exposed on the outside after the outer disc 2 of the disc brake is worn. Maintenance personnel can judge the degree of wear by the different colors exposed on the multi-layer dye plate 65. When the outer disc 2 and the inner disc 1 of the disc brake are installed, the insertion hole 64 can be matched with multiple protrusions 63, thus reducing the alignment process when installing the inner disc 1 and the outer disc 2 of the disc brake.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
