[0002] In the related art, brake discs are usually used in conjunction with brake calipers to slow down or stop the rotation of the wheels through friction, thereby achieving a braking effect.

[0028] Reference below Figure 1-Figure 5 A hub flange 100 according to an embodiment of the first aspect of the present invention is described.

[0029] like Figure 1-Figure 5 As shown, the hub flange 100 according to the embodiment of the first aspect of the utility model includes a hub body 1 and a connecting member 2.

[0030] Specifically, the hub body 1 is formed with a plurality of first through holes 11. In the description of the present utility model, "plurality" means two or more. The plurality of first through holes 11 are spaced apart along the circumference of the hub body 1, and the fasteners pass through the first through holes 11 and are connected to the wheel core. The connecting member 2 is provided in the thickness direction of the hub body 1 (for example, Figure 1On one side of the front-to-back direction), the connecting member 2 is suitable for abutting against the brake disc 201, and a heat dissipation channel is formed on the connecting member 2, and the heat dissipation channel is adjacent to the brake disc 201.

[0031] For example, in Figure 4 In the example, ten first through holes 11 are formed on the hub body 1, and fasteners are suitable for being inserted into the first through holes 11 to achieve the connection between the hub body 1 and the wheel core, thereby improving the connection stability and reliability between the hub body 1 and the wheel core.

[0032] The heat dissipation channel is adjacent to the brake disc 201, which ensures the connection stability between the connecting piece 2 and the hub body 1 while connecting the space between the brake disc 201 and the hub body 1 to the outside atmosphere. The heat generated by the brake disc 201 is dissipated through the heat dissipation channel, that is, the higher temperature gas in the space between the brake disc 201 and the hub body 1 can be cooled by heat exchange with the outside atmosphere through the heat dissipation channel, and / or the higher temperature gas in the space between the brake disc 201 and the hub body 1 can flow to the outside along the heat dissipation channel, and / or the lower temperature gas in the outside can enter the space between the brake disc 201 and the hub body 1 along the heat dissipation channel. This is beneficial for dissipating the heat generated by the brake disc 201 and preventing the heat from accumulating in the space between the brake disc 201 and the wheel hub body 1 for a long time, thereby reducing the temperature of the brake disc 201 and components such as the wheel hub bearing connected to the brake disc 201, preventing the brake disc 201 from overheating and prone to defects such as cracking and fissures, improving the use stability of the brake disc 201 and components such as the wheel hub bearing connected to the brake disc 201, extending the life of the brake disc 201 and components such as the wheel hub bearing, and reducing costs.

[0033] When the hub body 1 is connected to the brake disc 201, the connector 2 is opposite to the brake disc 201, and the side of the connector 2 away from the hub body 1 abuts against the brake disc 201 along the thickness direction of the hub body 1. Thus, the heat dissipation structure of the brake disc 201 is simplified, the structure of the hub flange 100 is simplified, and the setting of the heat dissipation channel is conducive to the lightweight of the hub flange 100.

[0034] Optionally, a plurality of heat dissipation holes are formed on the brake disc 201 to further improve the heat dissipation of the brake disc 201. The brake disc 201 adopts a honeycomb ventilation structure to form air convection during the vehicle driving process, and quickly dissipate the heat generated by the brake disc 201 and the brake caliper.

[0035] According to the wheel hub flange 100 of the embodiment of the utility model, the connector 2 on the wheel hub flange 100 abuts against the brake disc 201, and the heat dissipation channel on the connector 2 is adjacent to the brake disc 201, so that the space between the brake disc 201 and the wheel hub body 1 is connected to the outside atmosphere, and the heat generated by the brake disc 201 is dissipated, and the heat is prevented from accumulating in the space between the brake disc 201 and the wheel hub body 1 for a long time, thereby reducing the temperature of the brake disc 201 and the wheel hub bearing and other components connected to the brake disc 201, improving the use stability of the brake disc 201 and the wheel hub bearing and other components, extending the service life of the brake disc 201 and the wheel hub bearing and other components, and reducing the cost. In addition, the structure of the wheel hub flange 100 is relatively simple, and the setting of the heat dissipation channel is conducive to achieving lightweight of the wheel hub flange 100.

[0036] According to some embodiments of the present invention, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 The connector 2 includes a plurality of connector columns 21, which are spaced apart along the circumference of the hub body 1. The side of each connector column 21 away from the hub body 1 is suitable for connecting the brake disc 201. The hub body 1, two adjacent connector columns 21 and the brake disc 201 jointly define a heat dissipation channel. The connector 2 includes ten connector columns 21 spaced apart along the circumference of the hub body 1. Each connector column 21 extends along the axial direction of the hub body 1. The side of the connector column 21 away from the hub body 1 is connected to the brake disc 201, thereby improving the connection stability between the hub body 1 and the brake disc 201, and further improving the stability of the heat dissipation channel, so as to ensure the heat dissipation of the brake disc 201. The heat dissipation channel jointly defined by the hub body 1, two adjacent connector columns 21 and the brake disc 201 has a large size, which is conducive to meeting the heat dissipation requirements of the heat generated by the brake disc 201.

[0037] According to some embodiments of the present invention, referring to Figure 1-Figure 5 The connector 2 further includes a plurality of first connecting plates 22, each of which is disposed between two adjacent connecting columns 21, and along the axial direction of the hub body 1, the height of the first connecting plate 22 is less than the height of the connecting column 21. Thus, while the first connecting plate 22, the two adjacent connecting columns 21 and the brake disc 201 jointly define a heat dissipation channel, the first connecting plate 22 is used to connect the two adjacent connecting columns 21, so as to improve the setting stability of the connecting columns 21 and prevent the plurality of connecting columns 21 from being displaced along the circumferential direction of the hub flange 100.

[0038] For example, in Figure 1 In the example of FIG. 1 , the connector 2 includes five first connector plates 22 to define five heat dissipation channels between the hub flange 100 and the brake disc 201. Figure 2 and Figure 5In the example of FIG. 1 , the connecting member 2 includes ten first connecting plates 22 to define ten heat dissipation channels between the hub flange 100 and the brake disc 201 .

[0039] Further, refer to Figure 3 , along the axial direction of the hub body 1, the maximum height difference between the first connecting plate 22 and the connecting column 21 is ΔH, where ΔH satisfies: 150mm≤ΔH≤300mm. When the maximum height difference between the first connecting plate 22 and the connecting column 21 along the axial direction of the hub body 1 is less than 150mm, the size of the heat dissipation channel defined by the first connecting plate 22, two adjacent connecting columns 21 and the brake disc 201 is small, and it is difficult to meet the heat dissipation requirements of the brake disc 201; when the maximum height difference between the first connecting plate 22 and the connecting column 21 along the axial direction of the hub body 1 is greater than 300mm, the height of the first connecting plate 22 along the axial direction of the hub body 1 is small, so it is difficult to meet the use requirements of the first connecting plate 22 connecting adjacent connecting columns 21. Therefore, by setting the maximum height difference between the first connecting plate 22 and the connecting column 21 along the axial direction of the hub body 1 to 150mm≤ΔH≤300mm, the size design of the heat dissipation channel is more reasonable to meet the heat dissipation requirements of the brake disc 201, and the height design of the first connecting plate 22 along the axial direction of the hub body 1 is more reasonable to meet the use requirements of the first connecting plate 22 connecting adjacent connecting columns 21.

[0040] Optionally, along the axial direction of the hub body 1, the first connecting plate 22 is recessed toward the hub body 1, and while ensuring the connection area between the first connecting plate 22 and the adjacent connecting column 21 along the circumferential direction of the hub body 1, the size of the heat dissipation channel is increased as much as possible, so that the first connecting plate 22 can be reliably connected to the adjacent connecting column 21 while the heat dissipation channel can meet the heat dissipation requirements of the brake disc 201.

[0041] According to some embodiments of the present invention, referring to Figure 1-Figure 2 , combined with Figure 4-Figure 5 , the surface of one side of each first connecting plate 22 away from the hub body 1 is recessed toward the center of the hub flange 100. The surface of the first connecting plate 22 facing the center of the hub flange 100 is suitable for fitting with the surface of the brake disc 201 to increase the anti-rotation friction between the hub flange 100 and the brake disc 201. The first connecting plate 22 is recessed toward the center of the hub flange 100 so that the cross-section of the first connecting plate 22 is roughly arc-shaped, which is conducive to the lightweight design of the hub flange 100, ensuring the fit between the first connecting plate 22 and the brake disc 201 while avoiding the large fitting surface between the first connecting plate 22 and the brake disc 201 causing the hub flange 100 to be heavy.

[0042] Further, refer to Figure 4, along the radial direction of the hub body 1, the maximum distance that the side surface of the first connecting plate 22 away from the center of the hub body 1 is recessed toward the center of the hub flange 100 is L, where L satisfies: 150mm≤L≤300mm. Among them, when the maximum distance that the side surface of the first connecting plate 22 away from the center of the hub body 1 is recessed toward the center of the hub flange 100 is less than 150mm along the radial direction of the hub body 1, when the fitting requirements of the first connecting plate 22 and the brake disc 201 are met, the fitting area between the first connecting plate 22 and the brake disc 201 is large, which is easy to increase the weight of the hub flange 100; when the maximum distance that the side surface of the first connecting plate 22 away from the center of the hub body 1 is recessed toward the center of the hub flange 100 is greater than 300mm along the radial direction of the hub body 1, the fitting area between the first connecting plate 22 and the brake disc 201 is small, and the anti-rotation friction between the hub flange 100 and the brake disc 201 is small, which is difficult to meet the use requirements. Therefore, by setting the maximum distance along the radial direction of the hub body 1, where the surface of one side of the first connecting plate 22 away from the center of the hub body 1 is recessed toward the center of the hub flange 100, to 150mm≤L≤300mm, the setting of the first connecting plate 22 is more reasonable, which is conducive to the lightweight design of the hub flange 100 while satisfying the fitting requirements between the first connecting plate 22 and the brake disc 201.

[0043] Specifically, refer to Figure 4 , along the radial direction of the hub body 1, the thickness of the connector 2 is d, where d satisfies: 1mm≤d≤3mm. Among them, when the thickness of the connector 2 along the radial direction of the hub body 1 is less than 1mm, the thickness of the connector 2 is small, so the structural strength of the connector 2 is small, and the connector 2 is prone to breakage during use, which reduces the life of the connector 2, thereby reducing the life of the hub flange 100; when the thickness of the connector 2 along the radial direction of the hub body 1 is greater than 3mm, the thickness of the connector 2 is large, which increases the weight of the connector 2, thereby increasing the weight of the hub flange 100. Therefore, by setting the thickness of the connector 2 along the radial direction of the hub body 1 to 1mm≤d≤3mm, the thickness of the connector 2 is set more reasonably, and the structural strength of the connector 2 is high, which is conducive to reducing the weight of the connector 2, thereby facilitating the lightweight design of the hub flange 100.

[0044] According to some embodiments of the present invention, referring to Figure 1 The connector 2 further includes a plurality of second connecting plates 23, each of which is disposed between two adjacent connecting columns 21, and the plurality of second connecting plates 23 and the plurality of first connecting plates 22 are arranged alternately along the circumferential direction of the hub body 1. In the axial direction of the hub body 1, the surface of one side of each second connecting plate 23 away from the hub body 1 is flush with the surface of one side of the connecting column 21 away from the hub body 1. For example, Figure 1In the example, the connector 2 includes five second connectors 2, which are arranged alternately along the circumference of the hub body 1, five first connector plates 22, and five second connector plates 23. Each second connector plate 23 and the connector column 21 can abut against the surface of the brake disc 201, thereby increasing the matching area between the hub flange 100 and the brake disc 201 and improving the limited stability of the heat dissipation channel.

[0045] Optionally, refer to Figure 2-Figure 5 A limiting groove 211 is formed at one end of the connecting column 21 away from the hub body 1, and the limiting groove 211 is formed on one side of the connecting column 21 away from the center of the hub flange 100 along the radial direction of the hub body 1. At least a portion of the brake disc 201 is adapted to cooperate with the limiting groove 211 to locate the relative position of the brake disc 201 and the hub flange 100, which is beneficial to connecting the brake disc 201 and the hub flange 100, while avoiding excessive connection between the brake disc 201 and the hub flange 100, so as to improve the connection stability between the brake disc 201 and the hub flange 100.

[0046] Optionally, the hub flange 100 is an aluminum alloy flange. However, the invention is not limited thereto. Using an aluminum alloy flange as the hub flange 100 is conducive to a lightweight design of the hub flange 100 , and at the same time, since the aluminum alloy flange has a high heat dissipation efficiency, it is conducive to improving the heat dissipation efficiency of the hub flange 100 .
