Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake disc technology, and in particular to a lightweight brake disc. Background Technology
[0002] A brake disc, simply put, is a round plate that rotates when the car is moving. The brake disc is clamped by the brake caliper to generate braking force. When you press the brake pedal, the caliper clamps the brake disc to slow down or stop the car. Lightweight brake discs are an important component of the automotive braking system. By using new materials and optimizing the design, weight can be reduced while improving braking performance.
[0003] Brake discs mainly consist of a mounting base and a disc body. When a vehicle brakes, the brake caliper pushes the brake pads to apply pressure to both sides of the brake disc, achieving deceleration and braking through friction. After a certain period of use, the disc body structure will wear down, affecting the braking performance of the brake disc, requiring replacement of the brake disc to avoid affecting the vehicle's operation. However, most existing brake discs are one-piece structures. When the disc body structure is severely worn and needs to be replaced, even if the mounting base is undamaged and can continue to be used, the entire brake disc still needs to be replaced. Even a perfectly intact mounting base needs to be replaced, resulting in high replacement costs and a certain waste of resources. Utility Model Content
[0004] This utility model discloses a lightweight brake disc, which aims to solve the technical problem that when the disc structure is severely worn and needs to be replaced, even if the mounting base is undamaged and can continue to be used, the entire brake disc still needs to be replaced, and the intact mounting base also needs to be replaced, resulting in high replacement costs and a certain waste of resources.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A lightweight brake disc includes a disc body mechanism and a mounting mechanism. The disc body mechanism includes a first brake pad, a mating ring is fixedly installed on the inner side of the upper end of the first brake pad, a second brake pad overlaps the upper end of the first brake pad, and fixing blocks are fixedly installed on the inner sides of both the first and second brake pads. A first mounting groove is formed in the middle of the fixing block, and a reinforcing rib is fixedly installed on the inner side of the first brake pad between the fixing blocks. The mounting mechanism includes a mounting base, a mating block is fixedly installed on the outer side of the mounting base, and a second mounting groove is formed inside the mating block.
[0007] By setting the mounting base to cooperate with the disc mechanism, it is easy to replace the disc mechanism separately after the brake pads are damaged. If the mounting mechanism is not damaged, it can be left for continued use, reducing the waste of resources. At the same time, the docking block and the fixing block cooperate to facilitate the replacement of the first brake pad and the second brake pad according to the specific damage of the brake pad.
[0008] In a preferred embodiment, a heat-conducting plate is fixedly installed on the upper end of the first brake pad, heat dissipation grooves are formed inside both the first and second brake pads, a slot is formed at the lower end of the second brake pad, a through groove is formed inside the mating ring, and a locking groove is formed on one side of the mounting base.
[0009] By setting the heat-conducting plate to cooperate with the slot, the structural strength of the connection between the first brake pad and the second brake pad is improved, thereby improving the overall strength of the disc mechanism. At the same time, the heat-conducting plate is designed in an arc shape, which forms an arc-shaped heat dissipation hole between the first brake pad and the second brake pad, improving the heat dissipation capacity of the disc mechanism.
[0010] As can be seen from the above, the lightweight brake disc provided by this utility model, by setting a mounting base to cooperate with the disc body mechanism, makes it easy to replace the disc body mechanism separately after the brake pads are damaged. If the mounting mechanism is not damaged, it can be left for continued use, reducing the waste of resources. At the same time, the mating block and the fixing block cooperate to facilitate the replacement of the first brake pad and the second brake pad according to the specific damage of the brake pad.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] The lightweight brake disc disclosed in this utility model is mainly used in scenarios where the disc body structure is severely worn and needs to be replaced, but the mounting base is undamaged and can continue to be used, it is still necessary to replace the entire brake disc and the intact mounting base, which results in high replacement costs and a certain waste of resources.
[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A lightweight brake disc includes a disc body mechanism 1 and a mounting mechanism 2. The disc body mechanism 1 includes a first brake pad 101, a docking ring 103 is fixedly installed on the inner side of the upper end of the first brake pad 101, and a second brake pad 104 overlaps the upper end of the first brake pad 101. Fixing blocks 108 are fixedly installed on the inner sides of both the first brake pad 101 and the second brake pad 104. A first mounting groove 109 is opened in the middle of the fixing block 108. A reinforcing rib 1010 is fixedly installed on the inner side of the first brake pad 101 between the fixing blocks 108. The mounting mechanism 2 includes a mounting base 201, a docking block 202 is fixedly installed on the outer side of the mounting base 201, and a second mounting groove 203 is opened inside the docking block 202. The upper end of the reinforcing rib 1010 is flush with the upper end of the fixing block 108. The inner diameters of the first mounting groove 109 and the second mounting groove 203 are the same.
[0019] In this embodiment, the lightweight brake disc adopts a detachable design. When the brake pads are severely worn, the brake disc can be removed from the car wheel hub. Then, the nuts inside the first mounting groove 109 and the second mounting groove 203 are loosened to remove the nuts, releasing the lock between the mating block 202 and the fixing block 108. Then, the mounting base 201 is rotated to disengage the mating block 202 from the fixing block 108 between the first brake pad 101 and the second brake pad 104, thus releasing the lock of the mating block 202. This allows the mounting mechanism 2 to separate from the disc body mechanism 1, facilitating independent removal of the brake pads after damage. Replace the disc mechanism 1. If the mounting mechanism 2 is undamaged, it can be retained for continued use, reducing resource waste. When one brake pad is severely worn and needs replacement, separate the first brake pad 101 from the second brake pad 104, releasing the mating ring 103 on the first brake pad 101 from the second brake pad 104. This facilitates replacement of the first brake pad 101 and the second brake pad 104 based on the specific damage condition, further reducing resource waste. When installing the disc mechanism 1 onto the mounting mechanism 2, separate the first brake pad 101 from the second brake pad 104. After 104 is fitted together, the mounting base 201 is inserted into the central cavity of the first brake pad 101 and the second brake pad 104, and the mounting base 201 is fitted with the reinforcing rib 1010. The reinforcing rib 1010 and the fixing block 108 on the first brake pad 101 are on the same plane, ensuring the accuracy of the position of the mounting base 201 and improving the structural strength of the first brake pad 101. Then, the mounting base 201 is rotated so that the mating block 202 is inserted between the fixing block 108 of the first brake pad 101 and the fixing block 108 of the second brake pad 104, and the first mounting groove 109 is aligned. Align and connect with the second mounting groove 203, then insert the nut into the first mounting groove 109 and the second mounting groove 203 and tighten it to lock the mounting mechanism 2 and the disc mechanism 1. This facilitates locking and disassembling the disc mechanism 1. The inner diameters of the first mounting groove 109 and the second mounting groove 203 are the same, which makes it easy for the nut to pass through and fix the fixing block 108 and the docking block 202. This prevents the fixing block 108 or the docking block 202 from shaking after the holes in the first mounting groove 109 and the second mounting groove 203 are different sizes, thus affecting the stability of the brake disc after installation.
[0020] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a heat-conducting plate 102 is fixedly installed on the upper end of the first brake pad 101. Both the first brake pad 101 and the second brake pad 104 have heat dissipation grooves 105 inside. The lower end of the second brake pad 104 has a slot 106. The mating ring 103 has a through groove 107 inside. The mounting base 201 has a locking groove 204 on one side. An arc-shaped heat dissipation channel is formed between the heat-conducting plates 102. The heat dissipation groove 105 is connected to the arc-shaped heat dissipation channel on the side near the central axis.
[0021] In this embodiment: When the brake disc is in use, it generates a large amount of heat. When the first brake pad 101 and the second brake pad 104 are fitted together, the heat-conducting plate 102 on the first brake pad 101 is inserted into the slot 106 on the second brake pad 104, thus achieving a fitted installation of the first brake pad 101 and the second brake pad 104. The heat-conducting plate 102 being inserted into the slot 106 improves the structural strength of the connection between the first brake pad 101 and the second brake pad 104, thereby improving the overall strength of the disc body mechanism 1. At the same time, the heat-conducting plate 102 has an arc-shaped design. After the first brake pad 101 and the second brake pad 104 are fitted together, the arc-shaped heat-conducting plate 102 forms an arc-shaped heat dissipation hole between the first brake pad 101 and the second brake pad 104. When the brake disc rotates with the wheel hub, the arc-shaped heat dissipation hole facilitates the dissipation of heat from the outside. Outside air is introduced between the first brake pad 101 and the second brake pad 104, while the heat dissipation groove 105 is connected to the arc-shaped heat dissipation channel, facilitating the drawing of outside air into the arc-shaped heat dissipation channel, thereby achieving rapid heat dissipation of the heat-conducting plate 102. Subsequently, the air is discharged through the through groove 107 of the docking ring 103, carrying away the heat from the first brake pad 101 and the second brake pad 104. The heat dissipation groove 105 improves the heat dissipation capacity of the first brake pad 101 and the second brake pad 104. At the same time, the heat dissipation groove 105 also improves the surface friction of the first brake pad 101 and the second brake pad 104, improving the braking effect of the brake disc and the heat dissipation capacity of the disc body mechanism 1, preventing the disc body mechanism 1 from overheating and being damaged after prolonged use, and extending the service life of the disc body mechanism 1. The brake disc is installed on the vehicle through the locking groove 204 of the mounting seat 201.
[0022] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
