Description

Technical Field

[0001] This utility model relates to the field of motorcycle brake shoe technology, specifically a motorcycle brake shoe that can reduce noise. Background Technology

[0002] Motorcycle brake shoes, also called brake pad brackets or brake pad supports, are a key component in a drum brake system. Their main function is to support and accommodate the brake pads, working in conjunction with the brake caliper or brake drum to achieve braking.

[0003] A motorcycle brake shoe with heat dissipation function, disclosed in patent publication number CN215171700U, includes a brake shoe, a first connecting block on the inner side of the brake shoe, a return spring on one side of the first connecting block, a threaded hole on the surface of the brake shoe away from the first connecting block, and an arc-shaped block on the outer side of the brake shoe. This motorcycle brake shoe with heat dissipation function, by incorporating the arc-shaped block, allows for easy removal of the arc-shaped block and friction pad together when the friction pad needs replacement due to excessive wear, facilitating replacement of the new friction pad without replacing the entire brake shoe. This provides convenience, saves costs, and conserves resources. Furthermore, by incorporating reinforcing ribs, several groups of reinforcing ribs evenly distributed on both sides of the brake shoe significantly enhance its strength, preventing the brake shoe from becoming too weak and easily damaged due to the presence of heat dissipation holes, thus improving the performance of the brake shoe.

[0004] Motorcycle brake shoes based on the above and similar principles have the drawback of not having a noise reduction function. If they do not have a noise reduction function, they will generate a lot of noise during braking, resulting in a poor driving experience and potentially affecting other people. At the same time, brake shoes without a noise reduction structure may cause vibration or resonance, leading to an unstable feel when braking, which is not conducive to improving the rider's driving experience. Therefore, this application is made. Utility Model Content

[0005] The purpose of this invention is to provide a motorcycle brake shoe that can reduce noise, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a noise-reducing motorcycle brake shoe, comprising two half brake shoes, each half brake shoe having a fixing plate installed on both sides of its inner wall, each fixing plate having a mounting hole, and a connecting spring installed in the mounting hole; the two half brake shoes are connected by the connecting spring to form a brake shoe; a heat dissipation mechanism for providing heat dissipation is installed on the inner wall of the half brake shoes; and a friction block is installed on the outer wall of the half brake shoes through a positioning noise reduction mechanism, thereby completing the positioning and installation of the friction block and sound absorption and noise reduction.

[0007] Furthermore, the heat dissipation mechanism includes several vertical grooves formed on the inner wall of the top of the semi-brake shoe, with a threaded ring rotatably connected to the vertical grooves via a thread, a top ring installed on the outer wall of the top of the threaded ring, and several copper pillars installed on the inner circumference of the threaded ring.

[0008] Furthermore, the positioning and noise reduction mechanism includes a positioning component and a noise reduction component. The positioning component includes a positioning block installed on the outer wall of the half brake shoe. A positioning groove corresponding to the positioning block is opened on the contact surface between the friction block and the half brake shoe. The positioning block is a hollow structure and has several mounting posts installed in it. Several mounting grooves are opened on the outer wall of the friction block. The friction block is installed on the half brake shoe by using the mounting grooves and mounting posts in conjunction with fixing bolts.

[0009] Furthermore, the noise reduction component includes sound-absorbing cotton installed in the positioning block, the outer wall of the sound-absorbing cotton is coated with a flame-retardant coating, and the outer wall of the friction block is provided with several ventilation slots.

[0010] Furthermore, a slot is provided in the middle of the outer wall of the positioning block, a square block is inserted into the slot, a filter screen is installed in the positioning block, and the square block is fixedly connected to the filter screen.

[0011] Furthermore, the inner wall of the semi-brake shoe is provided with several side grooves, several sound insulation cotton is installed on the inner wall of the semi-brake shoe, and several reinforcing ribs are installed on the top inner wall of the semi-brake shoe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This noise-reducing motorcycle brake shoe features a cooling system that provides overall heat dissipation, extending its lifespan. A positioning noise-reducing mechanism ensures proper installation of the friction block; aligning the positioning groove with the positioning block and inserting it guides the installation process. Simultaneously, it absorbs noise generated during friction block operation through sound-absorbing cotton inside the positioning block, achieving noise reduction, improving the driving experience, reducing the probability of resonance, enhancing the stability of the braking system, and extending its lifespan.

[0014] Meanwhile, a threaded ring is connected to the vertical groove via a screw thread, making the threaded ring easy to disassemble and replace or maintain according to actual usage needs. The copper pillar inside the threaded ring increases the contact area with air, accelerates the heat exchange rate, and improves the heat dissipation effect. The filter screen prevents the sound-absorbing cotton from directly contacting the friction block, avoiding damage to the sound-absorbing cotton due to excessive temperature of the friction block. The sound-absorbing cotton can be made of a high-melting-point sound-absorbing material. The positioning block and slot make it easy for staff to disassemble and install the filter screen, facilitating the replacement of the sound-absorbing cotton. The sound insulation cotton further enhances the noise reduction effect, and the side grooves provide further heat dissipation for the friction block while reducing noise and absorbing sound.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Motorcycle brake shoes are a key component in drum brake systems. Motorcycle brake shoes are required in motorcycle drum brake systems. The motorcycle brake shoes provided by this utility model are specifically designed for drum brake systems with sound absorption and noise reduction requirements. Before putting these motorcycle brake shoes into use, it is necessary to ensure that the friction blocks can work normally and that the screws in the components are accurately fixed, thereby ensuring the normal operation of the motorcycle brake shoes.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a noise-reducing motorcycle brake shoe, comprising two half brake shoes 1, with fixing plates 2 installed on both sides of the inner wall of the half brake shoes 1, and mounting holes provided on the fixing plates 2, with connecting springs 3 installed in the mounting holes. The two half brake shoes 1 are connected by the connecting springs 3 to form a brake shoe. A heat dissipation mechanism 6 for providing heat dissipation is installed on the inner wall of the half brake shoes 1, and a friction block 5 is installed on the outer wall of the half brake shoes 1 through a positioning noise reduction mechanism 7. The positioning noise reduction mechanism 7 completes the positioning and installation of the friction block 5 and the sound absorption and noise reduction.

[0023] It should be noted that the two semi-brake shoes 1, together with the connecting spring 3, form the entire brake shoe. The connecting spring 3 provides a connection between the semi-brake shoes 1 and facilitates the removal and installation of the brake shoes at the corresponding installation positions. The heat dissipation mechanism 6 provides heat dissipation for the entire brake shoe, which helps to extend the service life of the brake shoes. The positioning and noise reduction mechanism 7 provides a positioning effect for the installation of the friction block 5 and absorbs the noise generated by the friction block 5 during operation, thereby reducing noise, improving the driving experience, reducing the probability of resonance, improving the stability of the braking system, and extending its service life.

[0024] like Figure 4 As shown, the heat dissipation mechanism 6 includes several vertical grooves opened on the inner wall of the top of the semi-brake shoe 1. A threaded ring 601 is rotatably connected to the vertical grooves by a thread. A top ring 602 is installed on the outer wall of the top of the threaded ring 601. Several copper pillars 603 are installed on the inner circumference of the threaded ring 601.

[0025] It should be noted that the vertical slots allow for ventilation and heat dissipation. A threaded ring 601 is connected to the vertical slot via a threaded connection, making the threaded ring 601 easy to disassemble and replace or maintain according to actual usage needs. The copper pillar 603 inside the threaded ring 601 increases the contact area with the air, accelerates the heat exchange rate, and improves the heat dissipation effect.

[0026] like Figure 2 and Figure 3As shown, the positioning and noise reduction mechanism 7 includes a positioning component and a noise reduction component. The positioning component includes a positioning block 701 installed on the outer wall of the half brake shoe 1. A positioning groove 702 corresponding to the positioning block 701 is opened on the contact surface between the friction block 5 and the half brake shoe 1. The positioning block 701 is a hollow structure. Several mounting posts 705 are installed in the positioning block 701. Several mounting grooves 704 are opened on the outer wall of the friction block 5. The friction block 5 is installed on the half brake shoe 1 by using the mounting grooves 704 and the mounting posts 705 in conjunction with the fixing bolts.

[0027] It should be noted that when installing the friction block 5, the positioning groove 702 can be aligned with the positioning block 701 and inserted to achieve the effect of guiding the installation. When the positioning block 701 is fully inserted into the positioning groove 702, the mounting groove 704 will coincide with the mounting post 705, so that the workers can install the fixing bolts.

[0028] like Figure 2 and Figure 3 As shown, the noise reduction component includes sound-absorbing cotton 708 installed in the positioning block 701. The outer wall of the sound-absorbing cotton 708 is coated with a flame-retardant coating, and the outer wall of the friction block 5 is provided with several ventilation slots 703.

[0029] It should be noted that the sound-absorbing cotton 708 inside the positioning block 701 can absorb the noise generated by the friction block 5 during operation, thus achieving a noise reduction effect. The flame-retardant coating can prevent the sound-absorbing cotton 708 from catching fire, which helps to improve safety. The ventilation slot 703 provides space for noise and enhances the sound absorption effect of the sound-absorbing cotton 708.

[0030] like Figure 3 As shown, a slot 709 is provided in the middle of the outer wall of the positioning block 701, a square block 707 is inserted into the slot 709, a filter screen 706 is installed in the positioning block 701, and the square block 707 is fixedly connected to the filter screen 706.

[0031] It should be noted that the filter screen 706 prevents the sound-absorbing cotton 708 from directly contacting the friction block 5, thus preventing the friction block 5 from overheating and damaging the sound-absorbing cotton 708. The sound-absorbing cotton 708 can be made of a sound-absorbing material with a high melting point. The positioning block 701, in conjunction with the slot 709, facilitates the disassembly and installation of the filter screen 706 by the staff, and makes it easy to replace the sound-absorbing cotton 708.

[0032] like Figure 1 As shown, the inner wall of the half brake shoe 1 has several side grooves, the inner wall of the half brake shoe 1 is equipped with several sound insulation cotton 4, and the top inner wall of the half brake shoe 1 is equipped with several reinforcing ribs.

[0033] It should be noted that the sound insulation cotton 4 can further improve the noise reduction effect, the side groove can further improve the heat dissipation of the friction block 5 while reducing noise and absorbing sound, and the reinforcing ribs can improve the strength of the semi-brake shoe 1.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
