Description

Technical Field

[0001] This utility model belongs to the field of front brake caliper technology, specifically relating to a high-durability front brake caliper. Background Technology

[0002] Brake calipers generate braking force by clamping the brake disc. When you press the brake pedal, the brake calipers clamp the brake disc to slow down or stop the vehicle.

[0003] This invention relates to a high-temperature resistant automotive front brake caliper disclosed in CN210240387U. The caliper includes a brake caliper body with a fixing groove on its lower surface. A fixing plate is fixedly mounted on the inner surface of the fixing groove. A fixing mechanism is provided on the surface of the fixing plate, including a limiting groove, a threaded groove, a positioning groove, a positioning block, a locking bolt, and a threaded hole. The surface of the first brake friction pad of this invention is fixed with a carbon fiber layer by a heat-insulating adhesive. This helps reduce the weight of the first brake friction pad and improves its heat dissipation through the carbon fiber layer. The first brake friction pad engages with the limiting groove, facilitating installation and preventing slippage on the surface of the fixing plate. Simultaneously, the positioning block engages with the positioning groove, allowing the locking bolt to be sequentially screwed into the threaded hole and threaded groove for fixation. Furthermore, the first brake friction pad is easily disassembled and replaced when worn, improving worker efficiency.

[0004] However, when the front brake caliper provided by the above-mentioned utility model is used, since the first brake friction pad is fixed on the fixed pad by the fixing mechanism, when the second brake friction pad comes into contact with the first brake friction pad, the force between the brake friction pads cannot be effectively buffered, resulting in greater wear of the brake friction pads and affecting the service life of the brake friction pads.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a high-durability front brake caliper that can solve the problem of brake friction pads not being able to buffer wear during use, resulting in excessive wear and affecting their service life.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A high-durability front brake caliper, comprising: The brake caliper body includes a brake caliper housing and a brake piston housing, which are integrally formed and connected together, improving the strength of the combined brake caliper housing and brake piston housing. A first brake friction pad is detachably mounted on the inner wall of the left end plate of the brake caliper housing, facilitating replacement of the first brake friction pad after damage. A second brake friction pad is slidably connected inside the brake piston housing. The second brake friction pad is driven to move by brake fluid, and braking is achieved when the second brake friction pad contacts the first brake friction pad.

[0008] The buffer assembly includes a mounting plate, which is fixedly connected to the inner wall of the left end panel of the brake caliper housing, ensuring the stability of the mounting plate after installation. A groove is formed on the right side wall of the mounting plate, and the left end of the first brake friction pad is installed in the groove, facilitating installation. A slow-release layer is provided between the inner wall of the groove and the left side wall of the first brake friction pad, and a slow-release ring is provided between the annular inner wall of the groove and the annular side wall of the first brake friction pad. When the front brake caliper engages braking, brake fluid drives the second brake friction pad to contact the first brake friction pad, achieving braking. To buffer the force between the second and first brake friction pads and reduce wear on the first brake friction pad, a buffer layer on the left side of the first brake friction pad and a buffer ring on its annular side effectively buffer the impact force, thereby reducing wear between the first and second brake friction pads. This also offers advantages such as noise reduction and improved braking performance. Furthermore, the first brake friction pad is mounted on a mounting plate using a fixing assembly, ensuring stability during use.

[0009] In one or more embodiments of this utility model, a brake fluid inlet is provided on the right side wall of the brake piston housing, and a brake fluid connector is integrally formed on the outer side wall of the right side wall of the brake piston housing at the brake fluid inlet. The brake fluid is delivered to the brake piston housing through the brake fluid connector, which can drive the second brake friction pad to move so that the second brake friction pad and the first brake friction pad can contact each other to achieve braking.

[0010] In one or more embodiments of this utility model, an oil seal ring is installed on the annular sidewall of the second brake friction pad. The distance between the left sidewall of the oil seal ring and the left end of the second brake friction pad is greater than the distance between the left end of the second brake friction pad and the right end of the first brake friction pad. This allows the second brake friction pad to continuously contact the inner sidewall of the brake piston housing during movement, thereby improving the sealing effect of the oil seal ring.

[0011] In one or more embodiments of this utility model, the slow-release layer is installed on the inner sidewall of the groove, and the left end of the slow-release layer abuts against the right end of the first brake friction pad, so that the slow-release layer can effectively buffer the impact force after the first brake friction pad is impacted.

[0012] In one or more embodiments of this utility model, the slow-release ring is installed on the annular inner sidewall of the groove, and the inner sidewall of the slow-release ring abuts against the annular sidewall of the first brake friction pad, so that when a lateral force occurs between the first brake friction pad and the second brake friction pad, the slow-release ring can effectively buffer the lateral force.

[0013] In one or more embodiments of the present invention, the fixing component includes a plurality of fixing plates, which are fixedly connected to the annular sidewall of the first brake friction pad at equal intervals, thereby fixing and installing the first brake friction pad.

[0014] In one or more embodiments of this utility model, the right sidewall of the mounting plate is provided with a plurality of screw holes that match a plurality of fixing plates at equal intervals, and the plurality of fixing plates are provided with mounting holes.

[0015] In one or more embodiments of this utility model, a plurality of fixing plates are fitted with screws through mounting holes. The threaded end of the screw is threaded into the corresponding screw hole. By installing the threaded end of the screw into the screw hole, the fixing plate can be fixed to the mounting plate through the screw, so as to fix the first brake friction pad to the mounting plate and make the first brake friction pad stable after installation.

[0016] In one or more embodiments of this utility model, a buffer ring and a washer are sleeved on the screw, and the buffer ring and washer are respectively disposed on the left and right sides of the fixing plate. Since the screw is mounted on the fixing plate through the mounting hole on the fixing plate, the fixing plate can move on the screw body. Therefore, when the first brake friction pad is impacted by the second brake friction pad, the first brake friction pad will drive the fixing plate to move, thereby the first brake friction pad and the fixing plate can compress the buffer layer and the buffer ring, so that the buffer layer and the buffer ring can buffer the impact of the first brake friction pad.

[0017] In one or more embodiments of this utility model, the slow-release layer, slow-release ring, and slow-release coil are made of rubber material with excellent wear resistance and noise reduction properties, so that the slow-release layer, slow-release ring, and slow-release coil can buffer the first brake friction pad and the second brake friction pad while reducing noise, and their wear resistance is good, thus improving their service life.

[0018] Compared with the prior art, this utility model is equipped with a buffer component. When the first brake friction pad comes into contact with the second friction brake pad for braking, and the first brake friction pad is impacted, multiple buffer components will effectively buffer the force it receives, thereby effectively reducing the wear between the brake friction pads, improving the service life of the friction pads and the braking effect, while also having a noise reduction effect.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0023] like Figures 1-3 As shown, a high-durability front brake caliper in one embodiment of the present invention includes a brake caliper body 1 and a buffer assembly 2.

[0024] like Figures 1-3 As shown, the brake caliper body 1 includes a brake caliper housing 11 and a brake piston housing 12. The brake caliper housing 11 and the brake piston housing 12 are integrally formed and connected together, which improves the strength of the combined brake caliper housing 11 and brake piston housing 12. A first brake friction pad 14 is detachably installed on the inner side wall of the left end plate of the brake caliper housing 11, making it easy to replace the first brake friction pad 14 after it is damaged. A second brake friction pad 15 is slidably connected inside the brake piston housing 12. The second brake friction pad 15 is driven to move by brake fluid, so that when the second brake friction pad 15 contacts the first brake friction pad 14, braking is achieved.

[0025] like Figures 1-3 As shown, a brake fluid inlet is provided on the right side wall of the brake piston housing 12. A brake fluid connector 13 is integrally formed on the outer side wall of the right side wall of the brake piston housing 12 at the brake fluid inlet. The brake fluid is delivered to the brake piston housing 12 through the brake fluid connector 13, which can drive the second brake friction pad 15 to move so that the second brake friction pad 15 and the first brake friction pad 14 can contact each other to achieve braking.

[0026] like Figure 2 and Figure 3 As shown, an oil seal ring 16 is installed on the annular sidewall of the second brake friction pad 15. The distance between the left sidewall of the oil seal ring 16 and the left end of the second brake friction pad 15 is greater than the distance between the left end of the second brake friction pad 15 and the right end of the first brake friction pad 14. This ensures that the second brake friction pad 15 will continuously contact the inner sidewall of the brake piston housing 12 during movement, thereby improving the sealing effect of the oil seal ring 16.

[0027] like Figures 2-4As shown, the buffer assembly 2 includes a mounting plate 21, which is fixedly connected to the inner wall of the left end panel of the brake caliper housing 11. This fixed connection ensures the stability of the mounting plate 21 after installation. A groove 22 is formed on the right side wall of the mounting plate 21. The left end of the first brake friction pad 14 is installed in the groove 22, which facilitates the installation of the left end of the first brake friction pad 14. A slow-release layer 23 is provided between the inner wall of the groove 22 and the left side wall of the first brake friction pad 14, and a slow-release ring 24 is provided between the annular inner wall of the groove 22 and the annular side wall of the first brake friction pad 14. When the front brake caliper engages braking, the brake fluid drives the second brake friction pad 15 to contact the first brake friction pad 14, thus achieving braking. To buffer the force between the second brake friction pad 15 and the first brake friction pad 14 and reduce wear on the first brake friction pad 14, a buffer layer 23 on the left side of the first brake friction pad 14 and a buffer ring 24 on the annular side of the first brake friction pad 14 are provided. These effectively buffer the impact force on the first brake friction pad 14, thereby effectively reducing wear between the first brake friction pad 14 and the second brake friction pad 15, while also reducing noise and improving braking performance. Furthermore, the first brake friction pad 14 is mounted on the mounting plate 21 using a fixing assembly. The fixing components ensure the stability of the first brake friction pad 14 during use.

[0028] like Figure 3 Combination Figure 4 As shown, the slow-release layer 23 is installed on the inner wall of the groove 22, and the left end of the slow-release layer 23 abuts against the right end of the first brake friction pad 14, so that the slow-release layer 23 can effectively buffer the impact force after the first brake friction pad 14 is impacted.

[0029] like Figure 3 Combination Figure 4 As shown, the slow-release ring 24 is installed on the annular inner sidewall of the groove 22. The inner sidewall of the slow-release ring 24 abuts against the annular sidewall of the first brake friction pad 14, so that when a lateral force occurs between the first brake friction pad 14 and the second brake friction pad 15, the slow-release ring 24 can effectively buffer the lateral force.

[0030] like Figure 3 Combination Figure 4 As shown, the fixing assembly includes multiple fixing plates 25, which are fixedly connected to the annular sidewall of the first brake friction pad 14 at equal intervals, so as to fix and install the first brake friction pad 14.

[0031] like Figure 3 Combination Figure 4 As shown, the right side wall of the mounting plate 21 has multiple screw holes 26 that match the multiple fixing plates 25 at equal intervals, and the multiple fixing plates 25 all have mounting holes.

[0032] like Figure 3 Combination Figure 4 As shown, multiple fixing plates 25 are equipped with screws 27 through mounting holes. The threaded end of the screw 27 is threaded into the corresponding screw hole 26. By installing the threaded end of the screw 27 into the screw hole 26, the fixing plate 25 can be fixed to the mounting plate 21 through the screw 27, so as to fix the first brake friction pad 14 to the mounting plate 21, making the first brake friction pad 14 stable after installation.

[0033] like Figure 3 Combination Figure 4 As shown, a buffer ring 28 and a washer 29 are fitted onto the screw 27, and the buffer ring 28 and washer 29 are respectively disposed on the left and right sides of the fixing plate 25. Since the screw 27 is installed on the fixing plate 25 through the mounting holes on the fixing plate 25, the fixing plate 25 can move on the shaft of the screw 27. Therefore, when the first brake friction pad 14 is impacted by the second brake friction pad 15, the first brake friction pad 14 will drive the fixing plate 25 to move. Thus, the first brake friction pad 14 and the fixing plate 25 can compress the buffer layer 23 and the buffer ring 28, so that the buffer layer 23 and the buffer ring 28 can buffer the impact of the first brake friction pad 14. At the same time, when the first brake friction pad 14 moves back and forth when the impact force changes, the washer 29 can buffer the force of the first brake friction pad 14 moving to the right, effectively reducing the force on the screw 27, ensuring the stability of the screw 27 after installation, and thus ensuring the stability of the first brake friction pad 14 after installation.

[0034] like Figure 3 Combination Figure 4 As shown, the slow-release layer 23, slow-release ring 24 and slow-release ring 28 are made of rubber material with excellent wear resistance and noise reduction performance, so that the slow-release layer 23, slow-release ring 24 and slow-release ring 28 can buffer the first brake friction pad 14 and the second brake friction pad 15 while playing a role in noise reduction. In addition, their wear resistance is good, which improves their service life.

[0035] When in use, when the front brake caliper brakes, the brake fluid drives the second brake friction pad 15 to move to the left. When the second brake friction pad 15 and the first brake friction pad 14 come into contact, the braking effect is achieved. At the same time, when the first brake friction pad 14 and the second brake friction pad 15 come into contact, the first brake friction pad 14 will be impacted and move to the left. When the first brake friction pad 14 moves, it drives the fixing plate 25 to move, so as to compress the slow-release layer 23 and the slow-release ring 28. The slow-release layer 23 and the slow-release ring 24 can effectively buffer the impact force on the first brake friction pad 14, effectively reducing the wear between the brake friction pads.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
