Description

Technical Field

[0001] The utility model relates to the technical field of automobile hubs, in particular to a lightweight automobile hub. Background Art

[0002] As an important part of the car, the wheel hub not only affects the appearance of the vehicle, but also directly affects the weight, handling performance and fuel economy of the vehicle. In order to reduce weight, the existing wheel hub is made of aluminum alloy to achieve the purpose of lightweighting.

[0003] However, the existing lightweight wheel design still has some shortcomings in practical applications:

[0010] The first support arm is provided with a first inclined surface inclined from the outer side of the wheel hub to the side of the hollow groove near the hollow groove. The first inclined surface is used to guide air when the wheel hub is running, so that air quickly enters the hollow groove and reaches the inside of the wheel hub.

[0011] In the above solution, preferably, the second support arm is provided with a second inclined surface on the side close to the hollow groove, which is inclined from the outer side of the hub to the side away from the hollow groove.

[0012] In the above solution, preferably, a plurality of guide grooves are provided on the inner side of the second support arm.

[0013] In the above solution, preferably, the guide groove includes a first notch provided on one side of the hollow groove and a second notch away from the side of the hollow groove, and the width of the first notch is greater than that of the second notch.

[0015] In the above solution, preferably, the number of the guide grooves is 2 or more, and their outer shape is a trapezoidal groove.

[0016] In the above solution, preferably, the wheel hub is made of aluminum alloy and is manufactured in one piece.

[0017] In the above solution, preferably, the guide groove is connected to the second inclined surface.

[0024] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments: Figures 1-4 A lightweight automobile wheel hub comprises three or more spokes 1 that are evenly arranged on the wheel hub. The spokes 1 are used to connect the center of the wheel hub and the rim. The spokes 1 are evenly arranged around the center of the wheel hub. The wheel hub is made of aluminum alloy and is integrally formed by stamping, so that the wheel hub has integrity and good rigidity.

[0025] In this embodiment, Figure 1As shown, there are 5 groups of spokes 1, which are radially divergent along the center of the hub. The middle part of the spoke 1 is provided with a hollow groove 101 which is equidistant from the spoke shape. Specifically, both sides of the spoke 1 extend outward from the center of the hub to the rim in a trapezoidal shape, and the hollow groove 101 is a trapezoidal hole groove, that is, Figure 2 Status shown.

[0026] The spoke 1 includes a first support arm 102 and a second support arm 103 arranged on both sides of the hollow groove 101. The outer side of the first support arm 102 is provided with a first inclined surface 104. The first inclined surface 104 is formed by the outer side of the hub being inclined inward toward the hollow groove 101. Figure 1 As shown in the counterclockwise rotation, air passes through the first inclined surface 104 and is guided into the hollow groove 101 , so that air quickly enters the interior of the hub when the hub rotates, achieving the effect of cooling the brake system in the hub.

[0027] The second support arm 103 is provided with a second inclined surface 105 which is inclined inward from the outer side of the hub to the side away from the hollow groove 101. Figure 3 As shown, after the air enters the hollow groove 101 through the first inclined surface 104 , it is guided by the second inclined surface 105 so that the air can circulate quickly inside the wheel hub.

[0028] like Figure 4 As shown, a plurality of guide grooves 106 are provided on the inner side of the second support arm 103. The guide grooves 106 are equidistantly arranged at two or more locations along the radial direction of the spoke 1. In this embodiment, three guide grooves 106 are provided, and their outer shape is a trapezoidal groove when viewed from the front. The guide grooves 106 include a first notch 201 provided on one side of the hollow groove 101 (i.e., the second inclined surface 105) and a second notch 202 away from the side of the hollow groove 101. The width of the first notch 201 is greater than that of the second notch 202. When air enters the hollow groove 101, it is guided by the second inclined surface 105 and then enters the first notch 201. The air flow rate discharged from the second notch 202 is further increased by squeezing the air between the notches with different diameters, thereby achieving a better cooling effect on the brake system.

[0029] The first notch 201 of the guide groove 106 is connected to the second inclined surface 105 .

[0030] The connection between the hollow groove 101, the hub center and the rim is provided with a third inclined surface 301 inclined inwardly. Figure 1-Figure 2 As shown, the third inclined surface 301 is used to further squeeze and guide the air entering the hollow groove 101 so that the air can quickly enter the hollow groove 101.

[0031] Use a method of lightweighting the wheel hub as described above: Figure 1As shown, the wheel hub rotates counterclockwise. Due to the rapid rotation of the wheel hub, the air quickly passes through the first inclined surface 104 into the hollow groove 101, and is then guided by the second inclined surface 105 on the other side of the hollow groove 101. After accelerated guidance by the guide groove 106, the brake system in the wheel hub is cooled, thereby improving the air diversion and heat dissipation effect of the wheel hub. While being lightweight, the hollow groove 101 and the guide groove 106 can be stamped and formed at one time by a mold, thereby improving the simplicity and convenience of manufacturing.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
