Description

Technical Field

[0001] This utility model relates to the field of brake disc technology, and in particular to a high carbon equivalent low alloy wear-resistant brake disc. Background Technology

[0002] High carbon equivalent low alloy wear-resistant brake discs are high-performance automotive brake components. Through reasonable composition design and advanced manufacturing processes, they achieve a balance of high wear resistance, thermal fatigue resistance, and corrosion resistance, providing reliable protection for safe driving.

[0003] A search revealed Chinese Patent Publication No. CN208749879U, which discloses a wear-resistant brake disc structure comprising a body, a connecting disc, a microcrystalline glass layer, and a filler. The connecting disc is fixedly connected to the body and is coaxial with it. The microcrystalline glass layer is disposed on the surface of the body that mates with the brake caliper. The filler is placed between the microcrystalline glass layer and the body, and the body and the microcrystalline glass layer are fixedly bonded together by the filler. This wear-resistant brake disc structure, by setting a microcrystalline glass layer on the brake disc body, avoids wear and corrosion caused by direct contact between the body and the brake caliper, thereby enhancing the wear and corrosion resistance of the brake disc. To enhance the wear resistance and thermal stability of the brake disc, the overall performance of the brake disc is optimized by adjusting the material composition. Low-carbon steel brake discs have received widespread attention due to their excellent processing performance, but their wear resistance still cannot fully meet the requirements of high-intensity braking, thus making them unsuitable for vehicle use. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high carbon equivalent low alloy wear-resistant brake disc, which aims to improve the problem that the wear resistance of the existing technology cannot fully meet the requirements of high-intensity braking, and thus cannot be fully used in vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high carbon equivalent low alloy wear-resistant brake disc, comprising two half brake discs, wherein mounting plates are installed on the front and rear sides of the top center of each half brake disc, and first screws are threaded to the left and right ends of the top of each mounting plate; a fixing disc is provided in the center of each half brake disc; fixing strips are slidably connected to adjacent sides of the two half brake discs; a first fixing ring is installed at the top center of each half brake disc; multiple second screws are threaded at equal intervals in the center of the first fixing ring; and a clamping mechanism is installed on the outer side of each half brake disc for clamping the brake disc.

[0006] The above technical solution combines two semi-brake discs and uses a fixing strip and mounting plate to ensure their stable installation. Tightening the first screws on both sides of the top prevents them from coming apart, thereby enhancing overall stability. The first fixing ring and the second fixing ring are installed at the upper and lower ends of the semi-brake discs respectively, and connected to the fixed disc with the second screw. This not only improves the wear resistance and thermal stability of the brake discs, but also reduces production costs and simplifies the manufacturing process.

[0007] As a further description of the above technical solution:

[0008] The clamping mechanism includes a spring, which is installed at the top center of the half brake disc. Right-angle plates are fixedly connected to both the left and right sides of the spring. A connecting plate is fixedly connected to the top of the right-angle plates. Fixing plates are fixedly connected to the bottom of the two connecting plates on opposite sides. A fixing block is fixedly connected to the top of the connecting plates. A protective cylinder is fixedly connected to the middle of the right-angle plates.

[0009] The above technical solution involves the following steps during brake disc installation: First, the right-angle plate is passed through the center hole of the half-brake disc. Then, a mounting post is used to connect it to the bottom, while the outside is clamped by a fixing plate to prevent damage to the half-brake disc during installation. The right-angle plate is then opened by the action of a spring, passes through the center hole of the fixing disc, and is tightened. Finally, a fixing block is installed through a connecting plate, making it easy for operators to handle and improving installation efficiency.

[0010] As a further description of the above technical solution:

[0011] Mounting posts are fixedly connected to the top left and right ends of the right-angle plate.

[0012] The above technical solution ensures that the brake disc will not be damaged during clamping by installing the mounting post.

[0013] As a further description of the above technical solution:

[0014] A connecting short plate is fixedly connected to the bottom of the outer wall of the fixed plate.

[0015] The above technical solution avoids damage to the bottom of the brake disc during clamping by installing the connecting short plate.

[0016] As a further description of the above technical solution:

[0017] The fixed disc has multiple drainage holes spaced at equal intervals in the middle.

[0018] The above technical solution effectively prevents water from remaining in the brake disc for extended periods by creating multiple drainage holes.

[0019] As a further description of the above technical solution:

[0020] The bottom of the second screw is threaded with a second retaining ring.

[0021] The above technical solution allows for further fixation of the two semi-brake discs through the installation of the second fixing ring.

[0022] As a further description of the above technical solution:

[0023] The outer side of the semi-brake disc has multiple heat dissipation holes at equal intervals.

[0024] The above technical solution involves creating multiple heat dissipation holes on the brake disc. These holes allow the heat generated during braking to dissipate quickly, preventing heat buildup that could damage the brake disc.

[0025] As a further description of the above technical solution:

[0026] A sealing ring is provided at the top of the first fixing ring.

[0027] The above technical solution prevents the second screw from being worn during operation by installing a sealing ring.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, two half brake discs are combined, and a fixing strip and mounting plate are used to ensure a stable installation. By tightening the first screws on the top and sides, the discs are prevented from falling apart and stability is enhanced. A first fixing ring and a second fixing ring are installed at the upper and lower ends of the half brake discs, respectively, and the discs are connected and fixed by the second screws. The above structure not only improves the wear resistance and thermal stability of the brake discs, but also reduces costs and simplifies the manufacturing process.

[0030] 2. In this utility model, when installing the brake disc, first pass the right-angle plate through the center of the half brake disc, connect the bottom with the mounting post, and clamp the outside with the fixing plate. The installation of the connecting short plate can prevent damage to the half brake disc. The spring opens the right-angle plate, passes through the center hole of the fixing disc and clamps it. The fixing block is installed through the connecting plate, which is convenient to take out and improves the installation efficiency. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a high carbon equivalent low alloy wear-resistant brake disc, comprising two half brake discs 1. Mounting plates 4 are installed on the front and rear sides of the top center of each half brake disc 1. First screws 11 are threaded to the left and right ends of the top of the mounting plates 4. The two half brake discs 1 are connected together by the first screws 11 through the installation of the mounting plates 4. A fixing disc 6 is provided in the center of each half brake disc 1. Fixing strips 3 are slidably connected to adjacent sides of the two half brake discs 1. A first fixing ring 8 is installed at the top center of each half brake disc 1. Multiple second screws 14 are threaded at equal intervals in the center of the first fixing ring 8. The threaded connection between the second screws 14 and the first fixing ring 8 makes the device more securely installed. A clamping mechanism 2 is installed on the outer side of each half brake disc 1 for clamping the brake disc. A second fixing ring 13 is threaded to the bottom of the second screws 14, and a sealing ring 5 is provided at the top of the first fixing ring 8.

[0040] Specifically, firstly, two half-brake discs 1 are combined together and secured at their connection point with fixing strips 3. To further ensure stability during use, a mounting plate 4 is installed on top. Next, the entire structure is further secured by tightening the first screws 11 on both sides, thus preventing it from coming apart during use. The fixing strips 3 are located in the middle and further enhance installation stability. To strengthen the integrity of the structure, a first fixing ring 8 and a second fixing ring 13 are installed on the top and bottom of the half-brake discs 1, respectively. The first fixing ring 8 and the second fixing ring 13 are connected by installing the second screw 14, thus achieving the connection between the fixed disc 6 and the half-brake disc 1. Through the installation of the above structure, not only is the brake disc's wear resistance and thermal stability ensured, but production costs are also reduced. In addition, the above structure simplifies the manufacturing process.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The clamping mechanism 2 includes a spring 201, which is installed at the top center of the half brake disc 1. Right angle plates 202 are fixedly connected to both sides of the spring 201. The installation of the spring 201 allows the right angle plates 202 to be opened and clamp the two half brake discs 1. A connecting plate 203 is fixedly connected to the top of the right angle plate 202. A fixing plate 204 is fixedly connected to the bottom of the two connecting plates 203 on opposite sides. A fixing block 206 is fixedly connected to the top of the connecting plate 203. A protective cylinder 205 is fixedly connected to the middle of the right angle plate 202. The installation of the protective cylinder 205 makes it easier and more convenient to handle the clamping mechanism 2. Mounting posts 9 are fixedly connected to the top left and right ends of the right angle plate 202. A connecting short plate 12 is fixedly connected to the bottom of the outer wall of the fixing plate 204.

[0042] Specifically, during the installation of the brake disc, the right-angle plate 202 is first passed through the center of the half-brake disc 1. Then, through the action of the mounting post 9, the right-angle plate 202 is brought into contact with the bottom of the half-brake disc 1. At the same time, the fixing plate 204 is located on the outside of the half-brake disc 1 to firmly clamp it. To prevent damage to the half-brake disc 1 during clamping, the installation of the connecting short plate 12 will avoid such a situation. Through the connection of the spring 201, the right-angle plate 202 will be opened during clamping, thereby ensuring that it can pass smoothly through the hole in the center of the fixing disc 6 and be clamped. In addition, the fixing block 206, through the installation of the connecting plate 203, makes the entire device more convenient to pick up and use, thereby improving the efficiency of brake disc installation.

[0043] Reference Figure 1 , Figure 2 and Figure 3Multiple drainage holes 7 are equidistantly provided in the middle of the fixed disc 6, and multiple heat dissipation holes 10 are equidistantly provided on the outer side of the half brake disc 1.

[0044] Specifically, when water flows through the brake disc, the presence of multiple drainage holes 7 effectively prevents water from remaining inside the brake disc for extended periods. This allows water to drain quickly when the vehicle inevitably encounters water accumulation or other humid environments during operation, ensuring the normal operation of the braking system. Simultaneously, the brake disc generates significant heat during vehicle operation due to friction and braking. Multiple heat dissipation holes 10 on the brake disc rapidly dissipate this heat, preventing heat buildup and damage. These processes not only improve the brake disc's heat dissipation efficiency but also enhance its durability, ensuring the vehicle's safety and reliability during long-term operation.

[0045] Working principle: Two half-brake discs 1 are combined and engaged at their connection point by a fixing strip 3. To ensure a stable installation, a mounting plate 4 is installed on top, and then the first screws 11 on both sides are tightened to prevent them from coming apart during use. The fixing strip 3 in the middle makes the installation more stable. A first fixing ring 8 and a second fixing ring 13 are installed on the top and bottom of the half-brake disc 1, respectively, and they are connected by a second screw 14. This connects the fixed disc 6 to the half-brake disc 1. Through the installation of the above structure, the brake disc has good wear resistance and thermal stability, while reducing production costs and simplifying the manufacturing process.

[0046] When installing the brake disc, first pass the right-angle plate 202 through the middle of the half brake disc 1, and then make contact with the bottom of the half brake disc 1 through the mounting post 9. The fixing plate 204 on the outside of the half brake disc 1 will clamp it from the outside. The installation of the connecting short plate 12 will prevent damage to the half brake disc 1 during clamping. Through the connection of the spring 201, the right-angle plate 202 will be opened during clamping, and then pass through the hole in the center of the fixing disc 6 and clamp it. The installation of the fixing block 206 through the connecting plate 203 will make the device easier to pick up and improve the installation efficiency.

[0047] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
