Description

Lightweight tubeless wheel

Technical Field

The utility model belongs to the wheel field especially relates to a lightweight tubeless wheel.

Background

Tubeless wheels are wheels that have gained considerable development in recent years. Tubeless wheels comprise two main parts, namely a rim and a web, which are welded together at a joint.

With the vigorous development of the automobile industry, the new energy, energy conservation, environmental protection and other directions are the development trend of automobiles, and therefore, automobile enterprises pay more attention to the research on the lightweight of automobiles. Among them, the light weight of the wheel is a major subject of research.

The lightweight processing of car enterprise to the wheel at present stage is mainly the selection on the material, through the thickness that reduces the rim, because material thickness reduces, whether can reach due rigidity and intensity need be considered, and current wheel does not carry out the improvement of corresponding structure after reducing rim thickness for the wheel is difficult to satisfy the strength requirement.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect of the prior art, the utility model aims to solve the technical problem that a lightweight tubeless wheel is proposed, reduce rim thickness and make the wheel lightweight, through the setting of first widening section, arcuation strengthening rib and second widening section, improve wheel bulk strength.

To achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a pair of lightweight tubeless wheel, include: the rim, the both ends of rim all outwards extend there is the arcuation rim, and the outer end of arcuation rim is equipped with first widening section, and the spoke, its one end is located the inside of rim and welds the inner wall at the rim, has seted up the wind hole on the spoke, and the middle part of spoke is equipped with convex arcuation strengthening rib, and the arcuation strengthening rib encircles on the lateral wall of spoke, inflating valve, its one end sets up on the rim, and the other end sets up towards the wind hole.

Preferably, the spoke includes spoke body and second widened section, and the second widened section sets up the one end at the spoke body, and the second widened section welds the inner wall at the rim.

Preferably, the rim has a thickness of 3.9-4.5 mm.

Preferably, the material of the rim is alloy high-strength steel.

Preferably, the spokes have a thickness of 11.95-12.55 mm.

Preferably, the material of the rim is ultra-fine steel.

Preferably, 10 wind holes total, 10 wind holes along spoke circumference equidistance interval setting, and distribute on the arcuation strengthening rib.

Preferably, the spokes have a width of 116-.

Preferably, the rim has a width of 280-.

The utility model has the advantages that:

1. the thickness of the rim is reduced, and meanwhile, the strength of the rim is improved through the widening processing of the arc-shaped wheel flange, namely the arrangement of the first widening section.

2. The strength of the spoke is improved at the weak position of the spoke by additionally arranging the convex arc-shaped reinforcing ribs.

3. By widening the welding position, the composite welding seam is more reliable, and the overall strength of the wheel is further improved.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Those not described in detail in this specification are within the skill of the art. In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
