[0060] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0061] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0062] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0063] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0064] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0065] In the prior art, when the brake assembly is braking, the temperature of the brake disc 200 will suddenly rise. Although the brake disc 200 is provided with an air duct 202, which can allow cooling air to flow quickly inside the brake disc 200 and quickly dissipate heat from the brake disc 200, when the vehicle is on a mountain road with poor wind conditions, after multiple heavy braking, the extreme temperature of the brake disc 200 will rise to 600 to 700 degrees Celsius, at which point the temperature of the brake disc 200 will quickly radiate outward.

[0066] In existing brake assemblies, fenders are usually designed to shield stones that bounce up during vehicle driving and protect the brake disc 200, but they will hinder the airflow around the brake disc 200, resulting in poor heat dissipation, which will further increase the temperature of the brake disc 200 and further increase the temperature of the brake assembly.

[0067] Existing fenders are mostly single-layer stamping parts, and the material is mostly DC04 iron plate. A few high-end models use 316 stainless steel. Among them, iron fenders are electrophoretically painted black for corrosion protection. Long-term high temperature will cause the electrophoretic coating to fall off, affecting the rust prevention and aesthetics of the fender. Stainless steel fenders will turn yellow after being exposed to high temperature for a long time, resulting in poor visual effects.

[0068] In addition, the brake assembly of the prior art uses a lighter cast aluminum or forged aluminum steering knuckle 400, wherein the aluminum steering knuckle 400 will have a local strength reduction or even fail under the above high temperature conditions. In addition, long-term high temperature will also damage the rubber part used for shock absorption on the steering knuckle 400, causing plastic deformation of the rubber part.

[0069] The fender 100 according to the embodiment of the present application is first described in detail below with reference to the accompanying drawings.

[0070] like Figures 1 to 14 As shown, the fender 100 according to the embodiment of the present application includes: a disc body 10. The disc body 10 is provided with a hollow area 18 penetrating along the thickness direction thereof, and the disc body 10 is provided with an air duct 202, which penetrates the outer surface of the disc body 10 and forms at least two openings spaced apart in the radial direction of the disc body 10.

[0071] Specifically, the fender 100 can be mainly composed of a disc body 10, and the disc body 10 can include but is not limited to a circular, quasi-circular, annular, or quasi-annular thin plate structure. The disc body 10 can be arranged on one side of the brake disc 200 without affecting the ventilation and heat dissipation of the brake disc 200 and the installation of the caliper 300 and the steering knuckle 400.

[0072] The disc body 10 may be provided with a hollow area 18, and the hollow area 18 may penetrate the disc body 10 along the thickness direction of the disc body 10. Air may flow through the hollow area 18 to the brake disc 200, so that the brake disc 200 can dissipate heat through its own air duct 202. Optionally, the hollow area 18 may be arranged in the radial middle of the disc body 10, for example,

[0073] In addition, the disc body 10 is also provided with an air passage, which can penetrate the outer surface of the disc body 10 to form two or more openings, so that the outside air can enter the disc body 10. At least two of the multiple openings can be spaced apart in the radial direction of the disc body 10, so that the air can flow from the inside to the outside or from the outside to the inside in the disc body 10, which can cooperate with the airflow thrown toward the peripheral side during the high-speed rotation of the brake disc 200 to achieve rapid cooling of the disc body 10.

[0074] It should be noted that the air passage can extend in a straight line or a curve in the disc body 10 , which is not limited here. For example, the air passage can extend in the radial direction of the disc body 10 , or can extend obliquely relative to the radial direction of the disc body 10 .

[0075] In addition, the opening may be disposed on the side or peripheral surface of the disk body 10 , which is not limited here.

[0076] Therefore, according to the fender 100 of the embodiment of the present application, a hollow area 18 is provided on the disc body 10 to cooperate with the brake disc 200 to form a high-speed airflow in the middle, so that the brake disc 200 can throw out airflow to the circumferential side during high-speed rotation, and at least two openings radially spaced apart on the disc body 10 can cooperate with the gas flow generated by the brake disc 200 to introduce air into the airway into the disc body 10, thereby quickly cooling the disc body 10, and without affecting the heat dissipation of the brake disc 200, the fender 100 is quickly cooled, and the fender 100 is prevented from being yellowed or the electroplating paint falling off due to excessive temperature, thereby avoiding affecting the appearance and performance of the fender 100.

[0077] According to one embodiment of the present application, there are multiple air ducts, which are arranged along the circumference of the disc body 10. The provision of multiple air ducts is beneficial to improving the heat dissipation efficiency of the fender 100, while avoiding cooling dead corners and improving the uniformity of heat dissipation of the fender 100.

[0078] According to some other embodiments of the present application, the fender 100 also includes a first baffle 20, which is connected to the outer peripheral side of the disc body 10 and extends at least toward one side of the disc body 10, and the opening formed by the air passage penetrating the outer peripheral surface of the disc body 10 faces the first baffle 20.

[0079] Specifically, the outer edge of the disk body 10 may be provided with a first baffle 20, and the first baffle 20 may extend toward one side of the disk body 10, or the first baffle 20 may extend toward both sides of the disk body 10. The air passage may penetrate the outer peripheral surface of the disk body 10 to form an opening, and the opening may be an air inlet 203 or an air outlet 203, which is not limited here.

[0080] The first baffle 20 can be arranged opposite to the opening on the outer circumference of the disk body 10 in the radial direction of the disk body 10. When the opening on the outer circumference of the disk body 10 is an air inlet 203, the air inlet 203 faces the first baffle 20, and the first baffle 20 can guide the airflow on the side of the disk body 10 to flow into the air inlet 203. When the opening on the outer circumference of the disk body 10 is an air outlet 203, the air outlet 203 faces the first baffle 20, and the first baffle 20 can guide the airflow in the airway to flow to the side of the disk body 10.

[0081] In this embodiment, the first baffle 20 can guide the airflow to flow into or out of the airway, and at the same time separate the opening from the high-speed airflow outside the baffle, which is beneficial to increase the flow rate of the airflow in the disk body 10, thereby improving the heat dissipation efficiency.

[0082] In some specific embodiments of the present application, the first baffle 20 includes a first plate portion 21, which extends toward the first side of the disk body 10. The air channel includes a first air channel 11, which penetrates the outer peripheral surface of the disk body 10 to form a first air inlet hole 111. The first air channel 11 penetrates the second side surface of the disk body 10 to form a first air outlet hole 112. The first plate portion 21 is arranged opposite to the first air inlet hole 111 to guide the airflow on the first side of the disk body 10 to flow to the first air inlet hole 111.

[0083] Specifically, the brake disc 200 may be arranged on the second side of the brake disc 200, the brake disc 200 may be annular, and a through hole 201 may be provided in the middle of the brake disc 200. The through hole 201 may be communicated with the hollow area 18, and the brake disc 200 is further provided with an air duct 202, which penetrates the inner circumference and the outer circumference of the brake disc 200 along the radial direction of the brake disc 200, and the brake disc 200 is further provided with a plurality of air holes 203 on the side facing the fender 100, and the plurality of air holes 203 are communicated with the air duct 202.

[0084] During the high-speed rotation of the brake disc 200, the brake disc 200 draws air from the side where the fender 100 is provided, and part of the air flow enters the through hole 201. At the same time, the air hole 203 draws air into the air duct 202 of the brake disc 200, so that negative pressure is generated between the fender 100 and the brake disc 200.

[0085] The first plate portion 21 extends toward the first side of the disc body 10, that is, the extension direction of the first plate portion 21 is away from the brake disc 200. Therefore, under the blocking effect of the first plate portion 21, the high-speed flow of gas between the brake disc 200 and the fender 100 is basically not disturbed. Since negative pressure is formed between the brake disc 200 and the fender 100, the first air inlet 111 faces the brake disc 200. Therefore, under the influence of atmospheric pressure, air flows into the first air duct 11 through the first air inlet 111 in large quantities, and then blows out from the first air outlet 112, which can not only quickly cool the brake disc 200, but also cool the fender 100 without hindering the heat dissipation of the brake disc 200.

[0086] According to some optional embodiments of the present application, the first air outlet 112 is an oblong hole, which is conducive to increasing the area of ​​the first air outlet 112, increasing the amount of air flowing into the first air channel 11, and increasing the area of ​​the first air outlet 112 facing the brake disc 200, which is conducive to air entering the air hole 203 of the brake disc 200 more quickly, thereby improving the heat dissipation effect of the brake disc 200. The oblong hole can extend along the radial direction of the disc body 10.

[0087] According to some other embodiments of the present application, the first air outlet 112 is arranged in the middle part of the disc body 10 in the radial direction, which can prevent the first air outlet 112 from being affected by the high-speed airflow on the inner and outer sides of the disc body 10, and ensure that the first air outlet 112 can absorb air from the first air inlet 111 under the influence of the negative pressure on the second side of the disc body 10, which is beneficial to the cooling of the fender 100 and the brake disc 200.

[0088] In some specific embodiments of the present application, a first boss 16 is provided on the second side of the disc body 10, and the first air outlet 112 passes through the first boss 16. An end surface of the first boss 16 away from the disc body 10 may be a first plane 161. The first boss 16 is provided on the side of the disc body 10 facing the brake disc 200 to facilitate the processing of the first air outlet 112, avoid surface damage to the disc body 10 during processing, and help improve the strength of the disc body 10.

[0089] According to some optional embodiments of the present application, the first baffle 20 extends along the circumference of the disk body 10 .

[0090] Specifically, the first baffle 20 may be annular or fan-shaped, whereby the first baffle 20 is disposed opposite to a plurality of openings on the circumference of the disk body 10 to guide airflow into the openings or guide airflow out of the openings.

[0091] According to some other embodiments of the present application, the first baffle 20 extends in a wave shape in the circumferential direction of the disk body 10, and the wave-shaped portion protruding toward the periphery of the disk body 10 can be opposite to the opening on the outer peripheral surface of the disk body 10. Thus, the first baffle 20 can accumulate air at a position opposite to the opening on the outer peripheral surface of the disk body 10, and more gas can be guided to flow into the first air duct 11, which is beneficial to improving the cooling effect.

[0092] In some specific embodiments of the present application, the first baffle 20 extends outwardly at an angle toward at least one side of the disk body 10, so that the angle between the first baffle 20 and the disk body 10 can be an obtuse angle, which is beneficial to improve the smoothness of air flow, avoid turbulence at the first baffle 20, and reduce airflow separation and pressure loss.

[0093] According to some optional embodiments of the present application, the first baffle 20 has a smooth transition with the outer edge of the disk body 10, that is, the connection between the first baffle 20 and the disk body 10 can be streamlined, which is beneficial to reduce the resistance encountered by air when flowing into the first airway 11, and reduce airflow separation, turbulence and pressure loss.

[0094] According to some other embodiments of the present application, the first baffle 20 also includes a second plate portion 22, which extends toward the second side of the disk body 10, and the air duct also includes a second air duct 12, which penetrates the inner circumference of the disk body 10 to form a second air inlet hole 121, and the second air duct 12 penetrates the outer circumference of the disk body 10 to form a second air outlet hole 122, and the second plate portion 22 is arranged opposite to the second air outlet hole 122 to guide the airflow of the second air outlet hole 122 to flow to the second side of the disk body 10.

[0095] Specifically, the first baffle 20 may be mainly composed of a first plate portion 21 and a second plate portion 22 , and the first plate portion 21 and the second plate portion 22 may cooperate to form a Y shape.

[0096] The second plate portion 22 may be disposed at the outer edge of the disc body 10 and extend toward a side close to the brake disc 200. The second plate portion 22 may at least partially cover the outlet of the air duct 202 at the outer periphery of the brake disc 200, and the second plate portion 22 may be spaced apart from the outlet of the air duct 202, so as not to affect the outflow of air from the outlet of the air duct 202.

[0097] When the brake disc 200 rotates at high speed, the cold air in the air duct 202 cools the brake disc 200 and its temperature rises. The cold air is discharged outward at high speed through the outlet of the air duct 202 along the radial direction of the brake disc 200. Under the guidance of the second plate 22, the high-temperature gas is blown out quickly toward the side of the brake disc 200 away from the fender 100, that is, toward the side of the vehicle wheel hub. When the air is hot, the gas density decreases and the gas speed becomes faster.

[0098] As a result, the gas speed at the second air outlet 122 is accelerated, and a flow velocity difference is formed between the second air outlet 122 and the first air outlet 112. According to Bernoulli's principle, the pressure is low where the flow velocity is high, and the pressure is high where the flow velocity is low. The second air outlet 122 generates a siphon on the second air duct 12, so that the air flows from the second air inlet 121 to the second air outlet 122, thereby quickly cooling the fender 100.

[0099] In addition, since the second air outlet holes 122 are arranged on the outer circumference of the disk body 10 and the second air inlet holes 121 are arranged on the inner circumference of the disk body 10 , the second air passage 12 penetrates the disk body 10 in the radial direction of the disk body 10 , further enhancing the cooling effect.

[0100] In addition, since the air in the first air duct 11 flows from outside to inside and the air in the second air duct 12 flows from inside to outside, the cold air flowing rapidly in the first air duct 11 and the second air duct 12 of the disk body 10 in opposite directions can further improve the cooling efficiency while avoiding cooling dead corners, which is beneficial to the uniformity of the temperature of the fender 100.

[0101] In some specific embodiments of the present application, the first air channel 11 and the second air channel 12 are arranged at intervals along the circumference of the disk body 10. Specifically, one or more second air channels 12 may be provided between two adjacent first air channels 11, and one or more first air channels 11 may be provided between two adjacent second air channels 12, which is not limited here.

[0102] like Figure 3 and Figure 4 As shown, a second air duct 12 can be provided between two adjacent first air ducts 11, that is, a plurality of first air ducts 11 and a plurality of second air ducts 12 can be arranged in sequence at intervals, thereby, the cold air flowing rapidly in opposite directions in the first air duct 11 and the second air duct 12 can further improve the cooling efficiency while avoiding cooling dead corners.

[0103] According to some optional embodiments of the present application, the first air duct 11 and / or the second air duct 12 extend along the radial direction of the disk body 10. On the one hand, air can flow through the entire disk body 10 from the inside to the outside or from the outside to the inside along the radial direction of the disk body 10, which is beneficial to enhance the cooling effect. On the other hand, it also facilitates the processing of the first air duct 11 and the second air duct 12, reduces the processing difficulty, and thus reduces the production cost.

[0119] A bolt tube may be provided in the mounting hole 171, and the bolt may pass through the bolt tube to be connected to the brake disc 200. The provision of the bolt tube is beneficial to improving the structural stability of the airway on the one hand, and on the other hand, it can also prevent the air in the airway from directly contacting the bolt, thereby preventing turbulence in the airway.
