Embodiment 1

[0020] Such as figure 1 As shown, the strength strengthening structure of an asymmetric high-ventilation wheel of the present invention includes a rim 1 and a spoke 2 fixed on the rim 1, wherein the spoke 2 includes a mounting ring 21 coaxially located in the middle of the rim 1 and an integrated The five spokes 22 connected on the outer ring surface of the mounting ring 21 are uniformly distributed along the outer ring surface of the mounting ring 21, and the connecting ring 6 is coaxially embedded on the inner ring surface of the rim 1. The connecting ring 6 It is fixed on the rim 1 by intermittent welding, so that five sections of intermittent welds 7 are formed on the annular butt joint between the connecting ring 6 and the rim 1. The intermittent welds 7 are located at the outer ends of the spokes 22, and there are two sections of intermittent welds. The seam 7 is deflected clockwise by 10mm relative to the axial center plane of the spoke 22, and the two sections of inter...

Embodiment 2

[0022] Such as figure 2 As shown, the top angles 8 on the three inner ribs 5 are deflected counterclockwise by 8mm in the same direction relative to the mid-section of the corresponding spoke 22, and two of the three top angles 8 are adjacent to each other, and the other is spaced apart At the same time, the four side ribs 4 corresponding to the two sides of the two spokes 22 distributed at intervals are 0.8mm thicker than the rest of the side ribs 4, and the rest are exactly the same as in embodiment 1.

Abstract

The invention discloses a hub structure and provides a strength reinforcing structure for an asymmetrical wheel with a high-ventilation holes, which has the advantages of simple structure, good ventilation effect, high strength and good shock resistance and solves technical problems in the prior art that the strength of the hub structure is low, the hub structure is prone to deform, the shock resistance of the hub structure is poor, the ventilation performance of the hub structure is poor and so on. The strength reinforcing structure comprises a wheel rim and a wheel spoke unit which is arranged on the wheel rim, wherein the wheel spoke unit also comprises a mounting ring and a plurality of spokes; the mounting ring is coaxially arranged at the middle part of the wheel rim; the plurality of spokes are arranged on the outer ring surface of the mounting ring; external side ends of the spokes extend outwards to be fixed on the wheel rim; air holes are formed between the adjacent spokes; side reinforcing ribs are arranged on the two sides of the spokes in a radial direction, respectively; after the corresponding side reinforcing ribs at the internal side ends of the adjacent spokes are butt-jointed with each other, triangular internal reinforcing ribs are formed; thicknesses of the corresponding side reinforcing ribs on the two sides of at least two internal reinforcing ribs have differences; and relative to the split of an angle between the corresponding spokes, the top angles of at least two internal reinforcing ribs facing the center of the wheel rim are inclined to one side.

Description

technical field [0001] The invention relates to a wheel hub structure, in particular to an asymmetric high-ventilation hole wheel strength strengthening structure with good ventilation effect, high strength and good shock resistance. Background technique [0002] Existing automobile hubs are generally supported in the rim by disc-shaped spokes. In order to reduce weight and improve the ventilation effect, several air holes are arranged equidistantly on the spokes. As a result, the strength of the wheel hub is low, the shock resistance is poor, and it is easy to deform. At the same time, because the overall wheel hub adopts a fully symmetrical structure, the axial ventilation performance of the wheel hub is poor. [0003] The Chinese patent (publication number: CN202727863U) discloses a wheel hub, which includes a circular plate with a through hole in the center of the wheel shaft. There is an annular step-shaped boss on one side of the circular plate, and the first-stage bos...
