Description

Technical Field

[0001] This utility model belongs to the field of brake pad technology, specifically relating to an anti-deformation structure for high-speed motorcycle brake pads. Background Technology

[0002] Brake pads are a key component of a vehicle's braking system. They are mainly used to convert the vehicle's kinetic energy into heat energy through friction, thereby achieving deceleration or stopping.

[0003] In existing brake pads, the friction pads are in direct contact with the brake disc, generating braking force through friction to decelerate and stop the vehicle. However, as vehicle mileage increases, the friction pads gradually wear down and thin due to prolonged use. This not only leads to a decrease in braking performance, such as increased braking distance and reduced braking response speed, but may also increase driving safety hazards. When the friction pads wear down to a certain extent, the traditional approach is to replace the entire brake pad. While this restores braking performance, it significantly reduces the utilization rate of the brake pads, increases vehicle maintenance costs, and also wastes resources. Utility Model Content

[0004] The purpose of this invention is to provide a deformation-resistant structure for high-speed motorcycle brake pads, in order to solve the problem mentioned in the background art where brake pads rely on friction between the friction block and the brake disc to generate braking force, but as they wear out, the braking effect decreases. Although the traditional method of replacing the entire brake pad can restore performance, it significantly reduces the utilization rate of the brake pads and increases maintenance costs and wastes resources.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a deformation-resistant structure for a high-speed motorcycle brake pad, comprising: a metal substrate, a friction substrate on one side of the metal substrate, a friction block bonded to the outer wall of the friction substrate, a first threaded groove opened laterally inside the metal substrate, a main threaded rod screwed through the first threaded groove, a bearing mounted on the main threaded rod, and the main threaded rod connected to the friction substrate by means of the bearing.

[0006] The metal substrate has multiple guide grooves opened laterally inside, and multiple guide rods are slidably connected to the inner sidewall of the friction substrate. Each guide rod is adapted to be embedded in a guide groove. A limit component is provided between each guide groove and the guide rod, and an abutment component is provided on one side of each guide rod.

[0007] Preferably, the limiting component includes a limiting groove and a limiting block. The limiting groove is formed on the inner wall of the guide groove, and the limiting block is installed on the outer wall of the guide rod. The limiting groove and the limiting block are compatible with each other.

[0008] The abutting component includes a second threaded groove, a secondary threaded rod, and an abutting plate. The second threaded groove is laterally opened in the metal substrate and is connected to the guide groove. The secondary threaded rod is screwed through the second threaded groove, and the abutting plate is connected to one end of the secondary threaded rod located in the guide groove.

[0009] The metal substrate has a storage groove on the side near the friction substrate, and the bearing is located in the storage groove.

[0010] Through the above technical solution:

[0011] In use, the metal base plate serves as the foundation of the entire structure, firmly fixed in its corresponding position within the braking system, providing stable support and connection points for the entire brake pad assembly. Its design ensures the stability and reliability of the brake pad assembly under various braking conditions. The friction plate, located outside the metal base plate, is the core working component of the brake pad. Friction blocks are bonded to its outer wall, directly contacting the brake disc and generating braking force through friction to decelerate and stop the vehicle. The friction plate is designed not only to ensure tight contact with the brake disc but also to withstand the enormous frictional forces and heat during braking.

[0012] Over time, brake pads wear down and thin out due to prolonged use. To address this issue, the design incorporates a wear compensation mechanism:

[0013] Main threaded rod: The main threaded rod screws through the first threaded groove inside the metal substrate, and a bearing is mounted on it. The bearing not only reduces friction between the main threaded rod and the metal substrate, but also ensures smooth rotational adjustment.

[0014] Wear compensation process: When the friction block wears to a certain extent, rotating the main threaded rod allows the friction plate to move radially on the metal plate. This movement compensates for the wear of the friction block, ensuring that it always maintains close contact with the brake disc, thereby maintaining stable braking force.

[0015] To ensure the stability and accuracy of the friction substrate during movement, the structure is designed with guiding and limiting components:

[0016] Guide rods and guide slots: Multiple guide rods are slidably connected to the inner wall of the friction plate. These guide rods are fitted into multiple guide slots opened inside the metal plate. The diameter and length of the guide rods are precisely designed to ensure they fit perfectly into the guide slots, with appropriate gaps for free sliding. Simultaneously, the arrangement of the guide slots is optimized to ensure sufficient spacing between them, effectively preventing the guide rods from touching or interfering with each other during movement. Furthermore, a sliding connection (slider and groove cooperation) design is used between the guide rods and guide slots. This allows each guide rod to slide smoothly and freely within the guide slots when the friction plate moves, achieving precise guidance and stable movement, providing strong support for the stable operation of the entire brake pad system.

[0017] Limiting Components: The limiting components include a limiting groove and a limiting block. The limiting groove is formed on the inner wall of the guide groove, while the limiting block is mounted on the outer wall of the guide rod. When the guide rod moves, the limiting block slides within the limiting groove, thereby limiting the range of movement of the guide rod and preventing structural damage caused by excessive movement.

[0018] To further enhance the stability of the brake pads, the structure incorporates an abutment component:

[0019] After the position of the friction plate is determined, the interaction between the secondary threaded rods and the second threaded grooves, caused by screwing on each secondary threaded rod, pushes the abutment plate to one side of the guide rod, making it fit against the guide rod. This design makes the guide rod less likely to retract, thus preventing the friction plate from retracting during braking. This ensures that the friction block maintains a tight contact with the brake disc, improving the overall stability of the equipment.

[0020] This design not only achieves precise compensation for brake pad wear through the rotating main threaded rod, but also ensures the stability and accuracy of the friction plate movement through the cooperation of the guide rod and the limit block. Furthermore, the design of the abutment assembly further enhances the durability and reliability of the brake pads, enabling the entire braking system to maintain optimal performance under various operating conditions.

[0021] Preferably, a support substrate is placed directly below the metal substrate, and a plurality of bead grooves are evenly formed in a ring on the upper surface of the support substrate, with a ball installed in each of the plurality of bead grooves.

[0022] Specifically, after installation, the support base plate is located directly below the metal base plate and is securely fixed to the base of the braking system using bolts or other fastening methods. When the metal base plate moves radially to compensate for brake pad wear, it drives the balls on the support base plate to roll within ball grooves. These ball grooves are evenly distributed in a ring shape on the upper surface of the support base plate, ensuring that the balls provide uniform support throughout the entire movement path of the metal base plate.

[0023] As the friction plate moves radially on the metal substrate, the rolling action of the balls significantly reduces the direct friction between the friction plate and the support plate. This design not only reduces frictional resistance and improves the smoothness of movement, but also extends the service life of the brake pad assembly. Through the rolling of the balls, the support plate effectively supports the movement of the metal substrate and ensures the stability and reliability of the entire structure during braking.

[0024] Preferably, there are two metal substrates, which are symmetrically mounted directly above the supporting substrate, and soft pads are installed on the end faces of the two metal substrates that are in contact with each other.

[0025] Specifically, a soft pad is installed on the contacting end faces of the two metal substrates. The soft pad is made of a highly elastic, wear-resistant material, such as rubber or polyurethane. When the metal substrates come into contact with each other during movement, the soft pad absorbs impact and vibration through elastic deformation, reducing wear between the metal substrates and improving the overall vibration damping performance of the structure.

[0026] When the friction plate moves radially on the metal plate to compensate for brake pad wear, the two symmetrical metal plates work together to ensure that the movement path of the friction plate is stable and accurate. The presence of the pad not only absorbs the impact and vibration between the metal plates, but also reduces noise and vibration during braking, improving braking comfort.

[0027] With the symmetrical mounting of the bimetallic substrate and the shock-absorbing design of the soft pad, the entire brake pad assembly is subjected to balanced force during braking, resulting in smoother movement, further extending the service life of the brake pads, and improving the overall performance and reliability of the equipment.

[0028] Compared with the prior art, the beneficial effects of this utility model are:

[0029] (1) This utility model compensates for the wear of the friction block by setting a first threaded groove, a main threaded rod, and bearings. During use, the friction plate can be moved radially on the metal plate by rotating the main threaded rod, thereby effectively compensating for the wear of the friction block caused by use. In this way, this ingenious design can ensure that the friction block can maintain a tight fit with the brake disc at all times, stably outputting braking force, which not only extends the service life of the brake pads, but also further improves the overall performance of the braking system.

[0030] (2) This utility model achieves precise guidance and positioning by setting guide rods, guide grooves, and limiting components. During use, the ingenious design of the guide rods and guide grooves working together effectively ensures the stability and positional accuracy of the friction plate during movement. At the same time, the limiting components can further constrain the displacement range of the guide rods, effectively avoiding structural damage caused by excessive movement. Through this design, the precision and reliability of the brake pad assembly are significantly improved, laying a solid foundation for the smooth and safe advancement of the braking process and ensuring that the braking operation is foolproof.

[0031] (3) By setting up auxiliary threaded rods and abutment plates, this utility model makes it difficult for the friction plate to retract during braking. In use, the operator screws on each auxiliary threaded rod to make the abutment plate accurately positioned on one side of the guide rod and tightly fitted to the guide rod. In this way, the guide rod is reliably supported, effectively preventing its backward tendency, thereby ensuring that the friction plate can stably maintain its original position during braking and is not prone to retraction. This allows the friction block to continuously and stably fit tightly against the brake disc, providing a solid guarantee for the stable operation of the braking system and comprehensively improving the overall stability and reliability of the equipment.

Detailed Implementation

[0040] 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.

[0041] Please see Figures 1-7 As shown, the present invention provides the following technical solution: a deformation-resistant structure for a high-speed motorcycle brake pad, comprising: a metal substrate 1, a friction substrate 2 on one side of the metal substrate 1, a friction block 3 bonded to the outer wall of the friction substrate 2, a first threaded groove 4 opened laterally inside the metal substrate 1, a main threaded rod 5 screwed through the first threaded groove 4, a bearing 7 mounted on the main threaded rod 5, and the main threaded rod 5 connected to the friction substrate 2 by means of the bearing 7.

[0042] Multiple guide grooves 8 are opened laterally inside the metal substrate 1. Multiple guide rods 9 are slidably connected to the inner sidewall of the friction substrate 2, and each guide rod 9 is adapted to be embedded in each guide groove 8. A limit component is provided between each guide groove 8 and the guide rod 9, and an abutment component is provided on one side of each guide rod 9.

[0043] Furthermore, the limiting component includes a limiting groove 10 and a limiting block 11. The limiting groove 10 is formed on the inner wall of the guide groove 8, and the limiting block 11 is installed on the outer wall of the guide rod 9. The limiting groove 10 and the limiting block 11 are compatible with each other.

[0044] The abutting assembly includes a second threaded groove 12, a secondary threaded rod 13, and an abutting plate 14. The second threaded groove 12 is laterally opened in the metal substrate 1 and is connected to the guide groove 8. The secondary threaded rod 13 is screwed through the second threaded groove 12, and the abutting plate 14 is connected to one end of the secondary threaded rod 13 located in the guide groove 8.

[0045] A storage groove 6 is provided on the side of the metal substrate 1 near the friction substrate 2, and the bearing 7 is located in the storage groove 6.

[0046] Through the above technical solution:

[0047] In use, the metal substrate 1 serves as the foundation of the entire structure, firmly fixed to the corresponding position in the braking system, providing stable support and connection points for the entire brake pad assembly. Its design ensures the stability and reliability of the brake pad assembly under various braking conditions. The friction substrate 2, located outside the metal substrate 1, is the core working component of the brake pad. Friction blocks 3 are bonded to its outer wall, directly contacting the brake disc and generating braking force through friction to decelerate and stop the vehicle. The design of the friction substrate 2 must not only ensure close contact with the brake disc but also withstand the enormous frictional forces and heat during braking.

[0048] With prolonged use of the brake pads, the friction block 3 will gradually wear and thin. To address this issue, the structure is designed with a wear compensation mechanism:

[0049] Main threaded rod 5: The main threaded rod 5 screws through the first threaded groove 4 inside the metal substrate 1, and a bearing 7 is mounted on it. The bearing 7 not only reduces the friction between the main threaded rod 5 and the metal substrate 1, but also ensures smooth rotation adjustment.

[0050] Wear compensation process: When the friction block 3 wears to a certain extent, the friction plate 2 can be moved radially on the metal plate 1 by rotating the main threaded rod 5. This movement compensates for the wear of the friction block 3, ensuring that the friction block 3 can always maintain close contact with the brake disc, thereby maintaining stable braking force.

[0051] To ensure the stability and accuracy of the friction substrate 2 during movement, the structure is designed with guiding and limiting components:

[0052] Guide rods 9 and guide grooves 8: Multiple guide rods 9 are slidably connected to the inner wall of the friction base plate 2. These guide rods 9 are respectively adapted to be embedded in multiple guide grooves 8 opened inside the metal base plate 1. The diameter and length of the guide rods 9 are precisely designed to ensure that they fit perfectly into the guide grooves 8, and appropriate gaps are reserved to allow for free sliding. At the same time, the arrangement of the guide grooves 8 is also optimized to ensure that each guide groove 8 has sufficient spacing to effectively prevent the guide rods 9 from touching or interfering with each other during movement. In addition, the guide rods 9 and the guide grooves 8 adopt a sliding connection (slider and groove cooperation) design. In this way, when the friction base plate 2 moves, each guide rod 9 can slide smoothly and freely in the guide groove 8, thereby achieving a precise guiding effect and a stable movement state, providing strong support for the stable operation of the entire brake pad system.

[0053] Limiting assembly: The limiting assembly includes a limiting groove 10 and a limiting block 11. The limiting groove 10 is formed on the inner wall of the guide groove 8, while the limiting block 11 is mounted on the outer wall of the guide rod 9. When the guide rod 9 moves, the limiting block 11 slides within the limiting groove 10, thereby limiting the range of movement of the guide rod 9 and preventing structural damage caused by excessive movement.

[0054] To further enhance the stability of the brake pads, the structure incorporates an abutment component:

[0055] After the position of the friction base plate 2 is determined, by screwing on each of the secondary threaded rods 13, the interaction between the secondary threaded rods 13 and the second threaded groove 12 pushes the abutment plate 14 to one side of the guide rod 9, making it fit against the guide rod 9. This design makes it difficult for the guide rod 9 to retract, and thus makes it difficult for the friction base plate 2 to retract during braking, thereby ensuring that the friction block 3 can maintain close contact with the brake disc and improving the overall stability of the equipment.

[0056] This design not only achieves precise compensation for brake pad wear through the rotating main thread rod 5, but also ensures the stability and accuracy of the movement of the friction plate 2 through the cooperation of the guide rod 9 and the limiting block 11. Furthermore, the design of the abutment assembly further enhances the durability and reliability of the brake pads, enabling the entire braking system to maintain optimal performance under various operating conditions.

[0057] For further details, please refer to Figure 1 and Figure 4 As shown, a support substrate 15 is placed directly below the metal substrate 1. A plurality of bead grooves 16 are evenly and circumferentially formed on the upper surface of the support substrate 15, and a ball 17 is installed in each of the plurality of bead grooves 16.

[0058] Specifically, after installation, the support base plate 15 is located directly below the metal base plate 1 and is securely fixed to the base of the brake system by bolts or other fastening methods. When the metal base plate 1 moves radially to compensate for brake pad wear, the metal base plate 1 drives the balls 17 on the support base plate 15 to roll within the ball grooves 16. The ball grooves 16 are evenly distributed in a ring on the upper surface of the support base plate 15, ensuring that the balls 17 can provide uniform support under the entire movement path of the metal base plate 1.

[0059] When the friction plate 2 moves radially on the metal plate 1, the rolling action of the balls 17 significantly reduces the direct friction between the friction plate 2 and the support plate 15. This design not only reduces frictional resistance and improves the smoothness of movement, but also extends the service life of the brake pad assembly. Through the rolling of the balls 17, the support plate 15 can effectively support the movement of the metal plate 1 and ensure the stability and reliability of the entire structure during braking.

[0060] For further details, please refer to Figures 1-3 As shown, there are two metal substrates 1, which are symmetrically mounted directly above the support substrate 15, and soft pads 18 are mounted on the end faces of the two metal substrates 1 that are in contact with each other.

[0061] Specifically, a soft pad 18 is installed on the end faces of the two metal substrates 1 that are in contact with each other. The soft pad 18 is made of a highly elastic and wear-resistant material, such as rubber or polyurethane. When the metal substrates 1 come into contact with each other during movement, the soft pad 18 absorbs impact and vibration through elastic deformation, reducing wear between the metal substrates 1 and improving the shock absorption performance of the entire structure.

[0062] When the friction plate 2 moves radially on the metal plate 1 to compensate for brake pad wear, the two symmetrical metal plates 1 work together to ensure that the movement path of the friction plate 2 is stable and accurate. The presence of the pad 18 not only absorbs the impact and vibration between the metal plates 1, but also reduces noise and vibration during braking, improving braking comfort.

[0063] With the symmetrical mounting of the bimetallic substrate 1 and the shock absorption design of the soft pad 18, the entire brake pad assembly is subjected to balanced force during braking, making the movement smoother, further extending the service life of the brake pads, and improving the overall performance and reliability of the equipment.

[0064] 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 claims and their equivalents.
