[0002] The wheel hub flange is a component installed between the wheel hub and the brake disc. It can increase the lateral distance between the two wheels to improve the driving stability and anti-roll capability of the vehicle.

[0003] However, the installation of the flange blocks the brake disc, resulting in the brake disc being unable to be ventilated in time. Its heat dissipation performance is greatly reduced due to the installation of the flange, and the dust accumulated on the brake disc cannot be blown away, resulting in adverse phenomena such as abnormal brake noise. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to propose a wheel hub flange for solving the problem that the wheel hub flange blocks the brake disc, resulting in the inability of the brake disc to dissipate heat.

[0005] The technical solution adopted by the utility model to solve the technical problem is a wheel hub flange, wherein one end of the flange facing the brake disc has a heat dissipation end surface, and a plurality of heat dissipation units are provided on the heat dissipation end surface, and a plurality of the heat dissipation units are connected end to end, and the heat dissipation units include an air inlet groove and an air outlet groove, wherein the air inlet groove gradually inclines inwardly along the rotation direction of the flange, and the air outlet groove gradually inclines outwardly along the rotation direction of the flange;

[0006] In the same heat dissipation unit, the inner end of the air inlet groove is communicated with the inner end of the air outlet groove; in any two adjacent heat dissipation units, the outer end of the air inlet groove in one of the heat dissipation units is communicated with the outer end of the air outlet groove in the other heat dissipation unit.

[0007] Furthermore, a first connecting section is provided between any two adjacent heat dissipation units, two ends of the first connecting section are respectively connected to the outer end of the air inlet groove and the outer end of the air outlet groove, and the curvature of the first connecting section is consistent with the curvature of the outer edge of the flange.

[0008] Furthermore, the first connecting section is in communication with a peripheral side wall of the flange.

[0009] Furthermore, the air inlet groove and the air outlet groove both have a first side wall and a second side wall opposite to each other, and the first side wall is located on the outside of the second side wall, the outer end of the first side wall is connected to the peripheral side wall of the flange, and the outer end of the second side wall is located on the inner side of the peripheral side wall of the flange.

[0010] Furthermore, the depth of the air inlet groove is equal to the depth of the air outlet groove, and the depth of the first connecting section is greater than the depth of the air inlet groove / the air outlet groove.

[0011] Furthermore, the width of the air inlet groove is equal to the width of the air outlet groove, and the width of the first connecting section is greater than the width of the air inlet groove / the air outlet groove.

[0012] Furthermore, the heat dissipation unit also includes a second connecting section, two ends of which are respectively connected to the inner end of the air inlet groove and the inner end of the air outlet groove, and the curvature of the second connecting section is consistent with the curvature of the inner edge of the flange.

[0013] Furthermore, the air inlet groove and the air outlet groove are symmetrical about the midpoint of the second connecting section.

[0014] Furthermore, the air inlet groove is arranged in an arc shape;

[0015] The direction of the tangent of any point on the air inlet groove is defined as the first direction, and the direction of the radius of any point on the air inlet groove is defined as the second direction. The angle between the first direction and the second direction gradually decreases from the outer end of the air inlet groove toward the inner end of the air inlet groove.

[0016] Furthermore, the air outlet groove is arranged in an arc shape;

[0017] The direction of the tangent at any point on the air outlet groove is defined as the third direction, and the direction of the radius at any point on the air outlet groove is defined as the fourth direction. The angle between the third direction and the fourth direction gradually increases from the inner end of the air outlet groove toward the outer end of the air inlet groove.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] (1) A plurality of heat dissipation units are arranged on one end surface of the flange facing the brake disc, and each heat dissipation unit includes an air inlet slot and an air outlet slot. When the vehicle is running, air enters through the air inlet slot and passes through the air outlet slot, thereby taking away the heat from the flange and the brake disc, thereby dissipating the heat from the brake disc and avoiding abnormal noise caused by dust accumulation on the brake disc.

[0020] (2) The air inlet groove is gradually inclined inward along the rotation direction, and the air outlet groove is gradually inclined outward along the rotation direction, and the inner end of the air inlet groove is connected to the inner groove of the air outlet groove, so that air enters from the outer end of the air inlet groove, flows to the inner end of the air inlet groove, passes through the air outlet groove, and flows out from the outer end of the air outlet groove, taking away the heat on the flange and the brake disc to achieve heat dissipation. The inner and outer ends of the air inlet groove and the air outlet groove are distributed on the inner and outer sides of the flange, so that the air inlet groove and the air outlet groove can dissipate heat at different positions of the flange and the brake disc in the radial direction, thereby making the temperature of each position of the brake disc and the flange more uniform.

[0021] (3) Multiple heat dissipation units are connected end to end in sequence, and in any two adjacent heat dissipation units, the air outlet slot in one heat dissipation unit is connected to the air inlet slot in the other heat dissipation unit. The advantage of such a configuration is that the air passing through the air outlet slot in any heat dissipation unit can at least partially enter the air inlet slot in the adjacent heat dissipation unit. Although the air passing through the air outlet slot carries some residual heat, it can increase the air intake volume of the air inlet slot, and the increase in the air intake volume can significantly enhance its heat dissipation effect. At the same time, since all heat dissipation units are connected end to end, the air intake volume of all air inlet slots can be increased, and the overall heat dissipation effect is significantly improved.

[0022] (4) The depth and width of the air inlet groove and the air outlet groove are equal, so that the cross-sectional areas of the air inlet groove and the air outlet groove are equal, and the air flows more smoothly between the air inlet groove and the air outlet groove without causing turbulence. At the same time, the depth and width of the first connecting section are greater than the depth and width of the air inlet groove or the air outlet groove, so that the cross-sectional area of ​​the first connecting section is greater than the cross-sectional area of ​​the air inlet groove or the air outlet groove. When the flange rotates, negative pressure can be formed at the first connecting section, so that air can enter from the air inlet groove and the air in the air outlet groove can be sucked out at the same time.

[0023] (5) The first side wall of the air inlet groove is located outside the second side wall, so that the angle between the direction facing the outer end of the air inlet groove and the length direction of the first connecting section is smaller, which is conducive to the air at the first connecting section to enter the air inlet groove more smoothly. The first side wall of the air outlet groove is located outside the second side wall, so that the angle between the direction facing the outer end of the air outlet groove and the length direction of the first connecting section is smaller, which is conducive to forming negative pressure at the first connecting section and sucking out the air in the air outlet groove. In this way, the air flow speed in the air inlet groove and the air outlet groove is increased, and the heat dissipation effect is enhanced.

[0024] (6) The angle between the tangent direction of the air inlet groove and the radial direction is gradually reduced from the outside to the inside. The smaller the angle between the tangent direction of the outer end of the air inlet groove and the tangent direction of the outer edge contour, the more conducive it is for air to enter from the outer end of the air inlet groove, thereby improving the air intake efficiency. The entire air inlet groove is set to a curved arc, so that the length of the entire air inlet groove is extended while ensuring the angle of the outer end of the air inlet groove, so that it can cover a larger effective area; at the same time, the distance between the inner and outer ends of the air inlet groove in the direction perpendicular to the radius is shortened, so that more air inlet grooves can be arranged within a limited heat dissipation end surface, thereby enhancing the heat dissipation effect.

[0025] (7) The angle between the tangent direction of the air outlet groove and the radial direction is gradually increased from the inside to the outside. The smaller the angle between the tangent direction of the outer end of the air outlet groove and the tangent direction of the outer edge contour, the more conducive the air is to be discharged from the outer end of the air outlet groove, thereby improving the air outlet efficiency. The entire air outlet groove is set to be a curved arc, so that the length of the entire air outlet groove is extended while ensuring the angle of the outer end of the air outlet groove, so that it can cover a larger effective area; at the same time, the distance between the inner and outer ends of the air outlet groove in the direction perpendicular to the radius is shortened, so that more air outlet grooves can be arranged within a limited heat dissipation end surface, thereby enhancing the heat dissipation effect.

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] Please refer to Figure 1-Figure 4The utility model discloses a hub flange, wherein one end of the flange facing the brake disc has a heat dissipation end surface 100, and a plurality of heat dissipation units 200 are provided on the heat dissipation end surface 100, and a plurality of the heat dissipation units 200 are connected end to end, and the heat dissipation units 200 include an air inlet groove 210 and an air outlet groove 220, wherein the air inlet groove 210 gradually inclines inwardly along the rotation direction of the flange, and the air outlet groove 220 gradually inclines outwardly along the rotation direction of the flange;

[0035] In the same heat dissipation unit 200, the inner end of the air inlet groove 210 is communicated with the inner end of the air outlet groove 220; in any two adjacent heat dissipation units 200, the outer end of the air inlet groove 210 in one of the heat dissipation units 200 is communicated with the outer end of the air outlet groove 220 in the other heat dissipation unit 200.

[0036] Specifically, the present application provides a plurality of heat dissipation units 200 on one end surface of the flange facing the brake disc, and each heat dissipation unit 200 includes an air inlet groove 210 and an air outlet groove 220. When the vehicle is running, air enters through the air inlet groove 210 and passes through the air outlet groove 220, thereby taking away the heat on the flange and the brake disc, thereby dissipating the heat of the brake disc and avoiding abnormal noise and other undesirable phenomena caused by dust accumulation on the brake disc.

[0037] It should be emphasized that since the air inlet groove 210 gradually tilts inward along the rotation direction (the rotation direction here can be understood as the rotation direction of the flange when the vehicle moves forward), the air outlet groove 220 gradually tilts outward along the rotation direction, and the inner end of the air inlet groove 210 is connected to the inner groove of the air outlet groove 220, so that air enters from the outer end of the air inlet groove 210, flows to the inner end of the air inlet groove 210, passes through the air outlet groove 220, and flows out from the outer end of the air outlet groove 220, taking away the heat on the flange and the brake disc to achieve heat dissipation. Since the inner and outer ends of the air inlet groove 210 and the air outlet groove 220 are distributed on the inner and outer sides of the flange, the air inlet groove 210 and the air outlet groove 220 can dissipate heat at different positions of the flange and the brake disc in the radial direction, thereby making the temperature of each position of the brake disc and the flange more uniform.

[0038] More importantly, multiple heat dissipation units 200 are connected end to end in sequence, and in any two adjacent heat dissipation units 200, the air outlet slot 220 in one heat dissipation unit 200 is connected to the air inlet slot 210 in the other heat dissipation unit 200. The advantage of such a configuration is that the air passing through the air outlet slot 220 in any heat dissipation unit 200 can at least partially enter the air inlet slot 210 in the adjacent heat dissipation unit 200. Although the air passing through the air outlet slot 220 carries some residual heat, it can increase the air intake volume of the air inlet slot 210, and the increase in the air intake volume can significantly enhance its heat dissipation effect. At the same time, since all the heat dissipation units 200 are connected end to end, the air intake volume of all the air inlet slots 210 can be increased, and the overall heat dissipation effect is significantly improved.

[0039] Furthermore, a first connecting section 230 is provided between any two adjacent heat dissipation units 200, and both ends of the first connecting section 230 are respectively connected to the outer end of the air inlet groove 210 and the outer end of the air outlet groove 220, and the curvature of the first connecting section 230 is consistent with the curvature of the outer edge of the flange.

[0040] The first connecting section 230 is in communication with the peripheral side wall of the flange.

[0041] Specifically, the first connecting section 230 is communicated with the peripheral wall of the flange, that is, the first connecting section 230 is an opening or notch provided between the two heat dissipation units 200 for connecting the two heat dissipation units 200. The first connecting section 230 is communicated with the outside, which can ensure that air can enter the air inlet groove 210 from the first connecting section 230, and the hot air from the air outlet groove 220 can be discharged from the first connecting section 230. Of course, part of the hot air from the air outlet groove 220 is directly discharged from the first connecting section 230, and part of it enters the air inlet groove 210 in the next heat dissipation unit 200 again through the first connecting section 230, so as to increase the air intake of the air inlet groove 210.

[0042] Furthermore, the air inlet groove 210 and the air outlet groove 220 both have a first side wall 211 and a second side wall 212 that are opposite to each other, and the first side wall 211 is located on the outside of the second side wall 212, the outer end of the first side wall 211 is connected to the peripheral side wall of the flange, and the outer end of the second side wall 212 is located on the inner side of the peripheral side wall of the flange.

[0043] Specifically, the first side wall 211 of the air inlet groove 210 is located outside the second side wall 212, so that the angle between the direction facing the outer end of the air inlet groove 210 and the length direction of the first connecting section 230 is smaller, which is conducive to the air at the first connecting section 230 to enter the air inlet groove 210 more smoothly. The first side wall 211 of the air outlet groove 220 is located outside the second side wall 212, so that the angle between the direction facing the outer end of the air outlet groove 220 and the length direction of the first connecting section 230 is smaller, which is conducive to forming a negative pressure at the first connecting section 230, and sucking out the air in the air outlet groove 220. In this way, the air flow speed in the air inlet groove 210 and the air outlet groove 220 is increased, and the heat dissipation effect is enhanced.

[0044] Furthermore, the depth of the air inlet groove 210 is equal to the depth of the air outlet groove 220 , and the depth of the first connecting section 230 is greater than the depth of the air inlet groove 210 / the air outlet groove 220 .

[0045] The width of the air inlet groove 210 is equal to the width of the air outlet groove 220 , and the width of the first connecting section 230 is greater than the width of the air inlet groove 210 / the air outlet groove 220 .

[0046] Specifically, the depth and width of the air inlet groove 210 and the air outlet groove 220 are equal, so that the cross-sectional areas of the air inlet groove 210 and the air outlet groove 220 are equal, and the air flows more smoothly between the air inlet groove 210 and the air outlet groove 220, and is not easy to be turbulent. At the same time, the depth and width of the first connecting section 230 are greater than the depth and width of the air inlet groove 210 or the air outlet groove 220, so that the cross-sectional area of ​​the first connecting section 230 is greater than the cross-sectional area of ​​the air inlet groove 210 or the air outlet groove 220. When the flange rotates, negative pressure can be formed at the first connecting section 230, so that air can enter from the air inlet groove 210, and the air in the air outlet groove 220 can be sucked out at the same time.

[0047] Furthermore, the heat dissipation unit 200 also includes a second connecting section 240, both ends of which are respectively connected to the inner end of the air inlet groove 210 and the inner end of the air outlet groove 220, and the curvature of the second connecting section 240 is consistent with the curvature of the inner edge of the flange.

[0048] A second connecting section 240 is provided between the air inlet groove 210 and the air outlet groove 220 to effectively transfer and guide the air, thereby preventing the air from not being able to flow smoothly due to excessive changes in the angle of the connection between the inner end of the air inlet groove 210 and the inner end of the air outlet groove 220.

[0049] Among them, the curvature of the second connecting section 240 is consistent with the curvature of the inner edge of the flange, so that the minimum distance from any position of the second connecting section 240 to the inner edge of the flange is equal, the heat dissipation effect of the second connecting section 240 on each position of the inner edge of the flange is closer, and the temperature of each position on the inner edge of the flange is more uniform.

[0050] Furthermore, the air inlet groove 210 and the air outlet groove 220 are symmetrical about the midpoint of the second connecting section 240 .

[0051] Furthermore, the air inlet slot 210 is arranged in an arc shape;

[0052] The direction of the tangent at any point on the air inlet groove 210 is defined as the first direction, and the direction of the radius at any point on the air inlet groove 210 is defined as the second direction. The angle between the first direction and the second direction gradually decreases from the outer end of the air inlet groove 210 toward the inner end of the air inlet groove 210.

[0053] Specifically, the angle between the tangent direction of the air inlet groove 210 and the radial direction is gradually reduced from the outside to the inside. The smaller the angle between the tangent direction of the outer end of the air inlet groove 210 and the tangent direction of the outer edge contour, the more conducive the air is to enter from the outer end of the air inlet groove 210, thereby improving the air intake efficiency. The entire air inlet groove 210 is set to a curved arc, so that the length of the entire air inlet groove 210 is extended while ensuring the angle of the outer end of the air inlet groove 210, so that it can cover a larger effective area; at the same time, the distance between the inner and outer ends of the air inlet groove 210 in the direction perpendicular to the radius is shortened, so that more air inlet grooves 210 can be arranged within the limited heat dissipation end surface 100, thereby enhancing the heat dissipation effect.

[0054] Furthermore, the air outlet slot 220 is arranged in an arc shape;

[0055] The direction of the tangent at any point on the air outlet groove 220 is defined as the third direction, and the direction of the radius at any point on the air outlet groove 220 is defined as the fourth direction. The angle between the third direction and the fourth direction gradually increases from the inner end of the air outlet groove 220 toward the outer end of the air inlet groove 210.

[0056] Specifically, the angle between the tangent direction of the air outlet groove 220 and the radial direction is gradually increased from the inside to the outside, and the smaller the angle between the tangent direction of the outer end of the air outlet groove 220 and the tangent direction of the outer edge contour is, the more conducive the air is to be discharged from the outer end of the air outlet groove 220, thereby improving the air outlet efficiency. The entire air outlet groove 220 is set to a curved arc, so that the length of the entire air outlet groove 220 is extended while ensuring the angle of the outer end of the air outlet groove 220, so that it can cover a larger effective area; at the same time, the distance between the inner and outer ends of the air outlet groove 220 in the direction perpendicular to the radius is shortened, so that more air outlet grooves 220 can be arranged within the limited heat dissipation end surface 100, thereby enhancing the heat dissipation effect.
