Description

TECHNICAL FIELD

[0001] The utility model belongs to brake pad technical field, concretely relates to a wear -resisting heat -resisting type brake pad. BACKGROUND

[0002] Brake pad is the key part in the vehicle braking system, mainly used for converting the kinetic energy of the vehicle into heat energy through friction, so as to realize the deceleration or parking.

[0003] The existing brake pad when using, the design of friction plate is slightly simple, is not equipped with effective heat dissipation structure planning, so that the heat dissipation area is quite limited.In the long time or high intensity brake operation, the heat generated by friction plate is difficult to dissipate quickly, and it is easy to cause the brake pad to appear the condition of local overheating.Moreover, the connection between the brake pad, back plate and sound-absorbing plate at present mostly simply relies on adhesive, however, under the condition of high temperature and long time use, the adhesive strength of only relying on single adhesive will probably reduce, and then cause the problem of loosening or even falling off between components, which brings great negative influence to the overall stability and driving safety of brake pad. SUMMARY

[0004] The utility model discloses a kind of wear -resisting heat -resisting type brake pads, to solve the problem of insufficient heat dissipation in the above background technology, which is prone to local overheating;Pad, back plate and sound-absorbing plate are connected only by adhesive, and the adhesive strength decreases under high temperature or long time use, which may cause components to loosen and fall off, affecting the stability of brake pad and driving safety.

[0005] To achieve the above object, the utility model provides the following technical scheme: a kind of wear -resisting heat -resisting type brake pad, comprising: brake pad, the one side of the brake pad is equipped with back plate, the one side of the back plate is equipped with sound-absorbing plate, the one side of the sound-absorbing plate is equipped with heat conduction plate, the one side of the heat conduction plate is equipped with friction plate, multiple connecting components are equipped between the heat conduction plate and friction plate, multiple heat dissipation blocks are installed on the outer wall of the friction plate upper and lower end, multiple heat dissipation grooves are set up in the outer wall of the friction plate both sides.

[0006] Preferably, the connecting component includes connecting block and connecting groove, the connecting block is installed on the outer wall of friction plate close to heat conduction plate, the connecting groove is set up on the outer wall of heat conduction plate close to friction plate;

[0007] The connecting block and connecting groove are both semicylindrical, and the connecting block and connecting groove are mutually adapted;

[0008] The shape of the heat dissipation block is ladder-shaped, and the heat dissipation groove is semicylindrical.

[0009] Several heat dissipation channels are set up on the heat conduction plate, and the several heat dissipation channels penetrate the whole heat conduction plate.

[0010] Through the above technical solutions:

[0011] In use, the brake pad, as the core working component of the brake pad, is closely connected with the piston end of the brake system to ensure that the braking force can be effectively transmitted to the brake disc. The back plate is stably arranged on one side of the brake pad and serves as a support structure for the entire brake pad, providing the necessary rigidity and stability to withstand the huge pressure and impact generated during braking. To improve the comfort and reduce noise during braking, the sound-absorbing plate is ingeniously integrated on one side of the back plate. The sound-absorbing plate, with its special material and porous structure, absorbs and reduces the vibration and noise generated during braking, thereby greatly optimizing the driving experience. The friction plate is a key component of the brake pad, directly contacting the brake disc and generating braking force through friction to achieve the purpose of vehicle deceleration and parking.

[0012] To cope with the large amount of heat generated during friction, the friction plate is designed with a ladder-shaped heat sink. The heat sink adopts a ladder shape, so each heat sink has a larger surface area compared to traditional flat structures. With the stacking of multiple ladder layers, the overall surface area of the heat sink can be significantly expanded, thereby providing more heat dissipation space. The ladder-shaped heat sink not only increases the surface area, but its unique multi-layer structure can also effectively guide air flow. When the vehicle is in motion, air flows through these ladder-shaped heat sinks, forming turbulent flow between each ladder layer. This turbulent flow effect prolongs the contact time between air and the surface of the heat sink, allowing heat to be more quickly carried away by the air. In addition, semicircular cylindrical heat dissipation grooves are opened on both sides of the outer wall of the friction plate, which further expand the heat dissipation area and facilitate air circulation, ensuring that the heat generated during friction can be quickly dissipated.

[0013] The heat-conducting plate plays a crucial role between the friction plate and the back plate. It not only serves as a medium for heat transfer, but also relies on its efficient heat-conducting properties to quickly transfer and dissipate the heat generated by the friction plate. To strengthen the connection strength and heat transfer efficiency between the heat-conducting plate and the friction plate, a semicircular cylindrical connecting block and connecting groove are used between them. This design not only increases the contact area, making the adhesive bond more secure, but also optimizes the heat transfer path, ensuring that heat can be efficiently transferred from the friction plate to the heat-conducting plate.

[0014] The semicircular cylindrical design of the connecting block and connecting groove not only provides stable connection at the structural level, but also improves the heat transfer performance by increasing the contact area. After heat is transferred to the heat-conducting plate, it is quickly dissipated through the heat dissipation channels on it. These heat dissipation channels run through the entire heat-conducting plate, ensuring that heat can be evenly distributed and quickly dissipated, effectively preventing local overheating and further enhancing the overall heat dissipation and heat resistance performance of the equipment.

[0015] Through the above optimization design, the brake pad can achieve efficient heat management in the braking process. The ladder-shaped heat dissipation block and the semi-cylindrical heat dissipation groove greatly expand the heat dissipation area, promote air circulation, and promote the rapid dissipation of heat generated by friction. The semi-cylindrical connecting block and the connecting groove not only strengthen the connection strength, but also optimize the heat transfer path. The heat dissipation channel on the heat conduction plate further ensures the rapid dissipation of heat, thereby improving the overall heat dissipation and heat resistance of the brake pad. Such design not only improves the durability and reliability of the brake pad, but also ensures the stability and safety of the braking system.

[0016] The brake pad, back plate, sound-absorbing plate, heat-conducting plate and friction plate are pasted with adhesive. A plurality of bolts are additionally installed between the brake pad, back plate and sound-absorbing plate. Each bolt is equipped with a screwing block. A plurality of installation grooves are formed in the outer wall of the brake pad. Each screwing block is distributed in each installation groove. A plurality of limiting grooves are formed in the outer wall of each screwing block. A limiting assembly is arranged between each screwing block and installation groove.

[0017] Preferably, the limiting assembly comprises a movable groove, a limiting block and a spring. The movable groove is formed in the inner wall of the installation groove. The limiting block is located at one end of the movable groove close to the screwing block. A part of the limiting block is located in the movable groove. The spring is connected between the movable groove and the limiting block. The limiting block and the limiting groove are matched. A connecting rod is installed on the outer wall of the limiting block.

[0018] Through the above technical solution:

[0019] In actual working environment of the brake pad, the adhesive can provide initial bonding effect, but its performance is easily changed under high temperature and long-term use, which reduces the bonding strength and even causes the bonding to be not firm. Once this situation occurs, it may induce parts loosening and falling off, which seriously affects the braking performance and driving safety of the brake pad. To solve this problem, a plurality of bolts are additionally arranged between the brake pad, back plate and sound-absorbing plate, which greatly strengthens the mechanical strength of the structure and provides additional connection force, so that the parts will not loosen and separate even in extreme braking conditions.

[0020] Each bolt is equipped with a screwing block to tighten the bolt and ensure the stability and reliability of the connection. A plurality of installation grooves are formed in the outer wall of the brake pad. These installation grooves are specially used to accommodate the screwing blocks, so that they can be stably embedded.

[0021] In order to further prevent the loosening or rotation of the screwing block during the braking process, a limiting assembly is arranged between each screwing block and the mounting groove. The limiting assembly comprises a movable groove, a limiting block and a spring. When the screwing block is installed, the connecting rod is first pushed to temporarily avoid the limiting block from the rotation track of the screwing block, so as to prevent the installation of the screwing block from being hindered.

[0022] After the bolt is installed, the position of the screwing block is adjusted, and the spring pushes the limiting block to be clamped into the limiting groove. At this moment, the limiting block is closely fitted with the limiting groove, and the rotation range of the screwing block is limited, so that the loosening problem is effectively prevented. The spring is connected between the movable groove and the limiting block, and continuously provides elastic force, so that the limiting block is always closely fitted with the limiting groove, and the anti-loosening effect is further improved.

[0023] By adding a plurality of bolts between the brake pad, the back plate and the sound-absorbing plate, and by combining the screwing block, the limiting assembly and the connecting rod, the mechanical strength and the connection reliability of the brake pad structure are significantly improved. This design not only solves the problem of poor adhesion of the adhesive under high temperature and long time use conditions, but also ensures the stability and safety of the brake pad under various braking conditions by means of multiple anti-loosening means. The comprehensive design concept realizes the organic unity of stable structure and reliable function, and lays a solid foundation for the long-term and stable operation of the brake pad.

Detailed Implementation

[0035] 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.

[0036] Please see Figures 1-4 As shown, this utility model provides the following technical solution: a wear-resistant and heat-resistant brake pad, comprising: a brake pad 1, a back plate 2 on one side of the brake pad 1, a sound-absorbing plate 3 on one side of the back plate 2, a heat-conducting plate 4 on one side of the sound-absorbing plate 3, a friction plate 5 on one side of the heat-conducting plate 4, multiple connecting components between the heat-conducting plate 4 and the friction plate 5, multiple heat dissipation blocks 6 installed at the upper and lower ends of the outer wall of the friction plate 5, and multiple heat dissipation grooves 7 opened on both sides of the outer wall of the friction plate 5.

[0037] Furthermore, the connecting assembly includes a connecting block 8 and a connecting groove 9. The connecting block 8 is installed on the outer wall of the friction plate 5 near the heat-conducting plate 4, and the connecting groove 9 is opened on the outer wall of the heat-conducting plate 4 near the friction plate 5.

[0038] Both the connecting block 8 and the connecting groove 9 are semi-cylindrical, and the connecting block 8 and the connecting groove 9 are compatible with each other;

[0039] The heat sink 6 is shaped like a trapezoid, and the heat sink 7 is semi-cylindrical.

[0040] The heat-conducting plate 4 has several heat dissipation channels 10, and these heat dissipation channels 10 run through the entire heat-conducting plate 4.

[0041] Through the above technical solution:

[0042] During operation, the brake pad 1, as the core working component of the brake pad, is tightly connected to the piston end of the braking system to ensure that braking force can be effectively transmitted to the brake disc. The backing plate 2 is firmly mounted on one side of the brake pad 1, serving as the support structure for the entire brake pad and providing the necessary rigidity and stability to withstand the enormous pressure and impact generated during braking. To improve braking comfort and reduce noise, a sound damping plate 3 is ingeniously integrated into one side of the backing plate 2. The sound damping plate 3, with its special material and porous structure, absorbs and reduces vibrations and noise generated during braking, thereby significantly optimizing the driving experience. The friction plate 5 is a key component of the brake pad, directly contacting the brake disc and generating braking force through friction to achieve vehicle deceleration and parking.

[0043] To cope with the large amount of heat generated during friction, the friction plate 5 is designed with trapezoidal heat dissipation blocks 6. The trapezoidal shape of the heat dissipation blocks 6 provides a larger surface area compared to traditional planar structures. By stacking multiple trapezoidal layers, the overall surface area of ​​the heat dissipation blocks 6 is significantly expanded, providing more space for heat dissipation. The trapezoidal shape of the heat dissipation blocks 6 not only increases the surface area, but its unique multi-layered structure also effectively guides airflow. When the vehicle is in motion, airflow over these trapezoidal heat dissipation blocks 6 creates turbulence between each trapezoidal layer. This turbulence effect prolongs the contact time between the air and the surface of the heat dissipation blocks 6, allowing heat to be carried away more quickly. Furthermore, semi-cylindrical heat dissipation grooves 7 are formed on both sides of the outer wall of the friction plate 5. These grooves 7 further expand the heat dissipation area, aiding airflow and ensuring that the heat generated during friction is dissipated quickly.

[0044] The heat-conducting plate 4 plays a crucial role between the friction plate 5 and the back plate 2. It not only serves as a medium for heat transfer but also, thanks to its highly efficient thermal conductivity, rapidly dissipates the heat generated by the friction plate 5. To enhance the connection strength and heat conduction efficiency between the heat-conducting plate 4 and the friction plate 5, a semi-cylindrical connecting block 8 and a connecting groove 9 are used. This design increases the contact area, making the adhesive bond more firmly, and optimizes the heat transfer path, ensuring that heat can be efficiently transferred from the friction plate 5 to the heat-conducting plate 4.

[0045] The semi-cylindrical design of the connecting block 8 and the connecting groove 9 not only provides a stable connection at the structural level, but also improves heat transfer efficiency by increasing the contact area. After the heat is transferred to the heat-conducting plate 4, it is quickly dissipated through the heat dissipation channels 10 on it. These heat dissipation channels 10 run through the entire heat-conducting plate 4, ensuring that the heat can be evenly distributed and quickly dissipated, thereby effectively preventing local overheating and further enhancing the overall heat dissipation and heat resistance performance of the equipment.

[0046] Through the aforementioned optimized design, the brake pads achieve efficient thermal management during braking. The trapezoidal heat sink 6 and semi-cylindrical heat sink 7 significantly expand the heat dissipation area, promoting airflow and facilitating the rapid dissipation of heat generated by friction. The semi-cylindrical connecting block 8 and connecting groove 9 not only strengthen the connection but also optimize the heat transfer path. The heat dissipation channel 10 on the heat-conducting plate 4 further ensures rapid heat dissipation, thereby improving the overall heat dissipation and heat resistance performance of the brake pads. This design not only enhances the durability and reliability of the brake pads but also ensures the stability and safety of the braking system.

[0047] Please see Figures 1-7 As shown, the brake pad 1, back plate 2, muffler plate 3, heat conduction plate 4, and friction plate 5 are all bonded together with adhesive. Multiple bolts 12 are also installed between the brake pad 1, back plate 2, and muffler plate 3. Each bolt 12 is equipped with a screwing block 13. Several mounting grooves 11 are opened on the outer wall of the brake pad 1. Each screwing block 13 is distributed in each mounting groove 11. Several limiting grooves 16 are opened on the outer wall of each screwing block 13. Limiting components are provided between each screwing block 13 and the mounting groove 11.

[0048] Furthermore, the limiting assembly includes a movable groove 14, a limiting block 15, and a spring 17. The movable groove 14 is formed on the inner wall of the mounting groove 11. The limiting block 15 is located at one end of the movable groove 14 near the screw block 13, and a part of the limiting block 15 is located inside the movable groove 14. The spring 17 is connected between the movable groove 14 and the limiting block 15. The limiting block 15 and the limiting groove 16 are adapted to each other. A connecting rod 18 is installed on the outer wall of the limiting block 15.

[0049] Through the above technical solution:

[0050] In actual use, while the adhesive provides initial bonding in the working environment of brake pads, its performance is easily altered under high temperatures and prolonged use, leading to reduced bonding strength and even the risk of poor adhesion. If this occurs, it can cause components to loosen or detach, severely impacting braking performance and driving safety. To overcome this challenge, multiple bolts 12 were added between the brake pad 1, backing plate 2, and muffler plate 3, significantly strengthening the mechanical strength of the structure and providing additional connecting force to ensure that the components do not loosen or separate even under extreme braking conditions.

[0051] Each bolt 12 is equipped with a tightening block 13 to tighten the bolt 12, ensuring a secure and reliable connection. Several mounting grooves 11 are cut into the outer wall of the brake pad 1, which are specifically designed to accommodate the tightening block 13 so that it can be firmly inserted.

[0052] To further prevent the screw blocks 13 from loosening or rotating during the braking process, a limiting component is installed between each screw block 13 and the mounting groove 11. This limiting component includes the movable groove 14, the limiting block 15, and the spring 17. When installing the screw block 13, the connecting rod 18 should be moved first to temporarily keep the limiting block 15 away from the rotation trajectory of the screw block 13, thus preventing any obstruction to the installation of the screw block 13.

[0053] After bolt 12 is installed, adjust the position of the screw-on block 13 so that spring 17 pushes the limiting block 15 into the limiting groove 16. At this moment, the limiting block 15, with its tight fit with the limiting groove 16, limits the rotation range of the screw-on block 13, effectively preventing loosening. Spring 17 connects the movable groove 14 and the limiting block 15, continuously providing elastic force to ensure that the limiting block 15 always fits tightly against the limiting groove 16, further enhancing the anti-loosening effect.

[0054] By adding multiple bolts 12 between the brake pad 1, backing plate 2, and muffler 3, and integrating the coordinated design of the screw-on block 13, limiting assembly, and connecting rod 18, the mechanical strength and connection reliability of the brake pad structure are significantly improved. This design not only effectively solves the problem of weak adhesion that may occur under high temperature and long-term use conditions, but also ensures the stability and safety of the brake pads under various braking conditions through multiple anti-loosening measures. This comprehensive design concept achieves an organic unity of structural stability and functional reliability, laying a solid foundation for the long-term and stable operation of the brake pads.

[0055] 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.
