Description

Technical Field

[0001] The utility model relates to the technical field of disc brakes, in particular to a high-temperature resistant disc brake assembly. Background Art

[0002] A disc brake consists of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, high-pressure brake fluid pushes the brake pads, clamping them against the disc, producing a braking effect. A search revealed Chinese patent publication number CN215792348U, which discloses a high-strength disc brake assembly comprising a base layer, a waterproof layer, a low-temperature-resistant layer, and a high-strength layer. The base layer is positioned on top of the waterproof layer, which in turn is positioned on top of the low-temperature-resistant layer. The low-temperature-resistant layer is positioned on top of the high-strength layer. The waterproof layer comprises a composite silicate layer, a polyester fiber layer, and an epoxy fiber layer. The composite silicate layer is positioned on top of the polyester fiber layer, which in turn is positioned on top of the epoxy fiber layer. The present invention utilizes the low-temperature-resistant layer, polytrifluoroethylene (PTFE), parylene, polyethylene, polytetrafluoroethylene (PTFE), high-strength layer, epoxy resin, polyphenylene ether resin, and unsaturated polyester resin to provide low-temperature resistance during use, resulting in a more effective disc brake assembly. However, both polytrifluoroethylene and parylene in the disc brake assembly are heat-resistant, and polytrifluoroethylene is airtight. As a result, when the brake disc is working on the road for a long time, the temperature of the brake disc will slowly rise, and the cooling rate will be slow. Long-term use will cause the brake disc to be damaged due to excessive temperature, reducing its safety. Utility Model Content

Long-term use may cause the brake disc to be damaged due to excessive temperature, thereby reducing its safety.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a high-temperature resistant disc brake assembly, including a brake disc and a tetrafluoroethylene metal disc, the tetrafluoroethylene metal disc is fixedly connected to the inside of the brake disc, and the outer side wall of the tetrafluoroethylene metal disc is horizontal to the outer side wall of the brake disc, a plurality of waterproof grooves are evenly spaced inside the upper and lower side walls of the tetrafluoroethylene metal disc, and a plurality of grooves are evenly spaced inside the outer side wall of the tetrafluoroethylene metal disc.

[0005] Preferably, annular holes are provided inside the upper and lower ends of the tetrafluoroethylene metal disk, and multiple through holes are provided at equal intervals inside the upper and lower ends of the tetrafluoroethylene metal disk. The through holes correspond to the waterproof grooves respectively and are connected with the corresponding waterproof grooves respectively. The interiors of the through holes are connected with the interiors of the annular holes, thereby preventing water from accumulating inside the waterproof grooves.

[0006] Preferably, the grooves are all arranged at an angle, so as to accelerate the air flow around the tetrafluoroethylene metal disk.

[0007] Preferably, the bottom surfaces of the annular hole, the through hole and the waterproof groove are horizontal to each other, thereby preventing water from accumulating inside the buffer hole or the waterproof groove.

[0008] Preferably, the connection between the tetrafluoroethylene metal disc and the side wall of the brake disc is sealed by using sealant, thereby preventing gaps from appearing inside the brake disc.

[0009] The utility model provides a high-temperature resistant disc brake assembly. It has the following beneficial effects:

[0010] 1. This high-temperature resistant disc brake assembly, when in use, has a PTFE metal disc that not only has the hardness of metal, but also has the high-temperature resistance, low-temperature resistance, and corrosion resistance of PTFE. When the brake disc generates heat during use, the brake disc rotates, and the cooperation between the waterproof groove and the oblique groove allows the internal heat to dissipate.

[0011] 2. This high-temperature resistant disc brake assembly, when in use, can dissipate heat from the brake disc while placing water in the waterproof groove of the tetrafluoroethylene metal disc through the cooperation between the provided grooves, through the through holes and the buffer holes, thereby improving the waterproofness of the tetrafluoroethylene metal disc.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-4 The embodiment of the present invention provides a high-temperature resistant disc brake assembly, including a brake disc 1 and a tetrafluoroethylene metal disc 2. The tetrafluoroethylene metal disc 2 is fixedly connected to the inside of the brake disc 1, and the outer side wall of the tetrafluoroethylene metal disc 2 is horizontal to the outer side wall of the brake disc 1. A plurality of waterproof grooves 3 are arranged at equal intervals inside the upper and lower side walls of the tetrafluoroethylene metal disc 2, and a plurality of grooves 5 are arranged at equal intervals inside the outer side wall of the tetrafluoroethylene metal disc 2. The grooves 5 are all inclined. The connection between the tetrafluoroethylene metal disc 2 and the side wall of the brake disc 1 is sealed with sealant. When the brake disc 1 rotates with the wheel, the inclined grooves 5 can accelerate the flow of air around the tetrafluoroethylene metal disc 2. Then, the grooves 5 can be used to create a gap between the tetrafluoroethylene metal disc 2 and the brake disc 1, so that the heat generated in the tetrafluoroethylene metal disc 2 during braking can be dissipated.

[0019] Example 2: In order to facilitate the drainage of the accumulated water in the tetrafluoroethylene metal plate 2, in this embodiment, as shown in FIG. Figure 2-4 As shown, annular holes 6 are provided inside the upper and lower ends of the tetrafluoroethylene metal disc 2, and multiple through holes 4 are evenly spaced inside the upper and lower ends of the tetrafluoroethylene metal disc 2. The through holes 4 correspond to the waterproof grooves 3 respectively, and are respectively connected with the corresponding waterproof grooves 3. The interiors of the through holes 4 are all connected with the interiors of the annular holes 6. The annular holes 6, the through holes 4 and the bottom surfaces of the waterproof grooves 3 are horizontal to each other. When the brake disc 1 is used on rainy days, rainwater will enter the groove of the tetrafluoroethylene metal disc 2, and when the brake disc 1 is in a stationary state, the rainwater in the waterproof groove 3 will enter the interior of the buffer hole 6 through the through holes 4, so that the rainwater can enter the interior of the waterproof groove 3 through the adjacent through holes 4 and be discharged.

[0020] It should be noted that, in this embodiment, when the low-temperature resistant disc brake assembly is used, the brake disc 1 rotates with the wheel while utilizing the obliquely arranged grooves 5 to accelerate the flow of air around the tetrafluoroethylene metal disc 2. Then, utilizing the arranged grooves 5, a gap can be created between the tetrafluoroethylene metal disc 2 and the brake disc 1, so that the heat generated in the tetrafluoroethylene metal disc 2 during braking can be dissipated. When the brake disc 1 is used on rainy days, rainwater will enter the grooves of the tetrafluoroethylene metal disc 2, and when the brake disc 1 is in a stationary state, the rainwater in the waterproof groove 3 will enter the interior of the buffer hole 6 through the through hole 4, allowing the rainwater to enter the interior of the waterproof groove 3 through the adjacent through hole 4 and be discharged.
