Embodiment

[0040] Please refer to figure 1 , with reference to Figure 2 to Figure 8, the present application provides a variable property wheel 1, which mainly includes three parts: a rim 2, a spoke 6 and a hub 7. The rim 2 and the spoke 6 are molded into an integrated structure. The variable property wheel 1 has three characteristics of variable strength, variable thickness and variable section. The intensity of the stress concentration area of ​​the variable property wheel 1 is higher than that of other places, and there are at least three intensity change areas, and its cross-sectional structure is The design can be changed, that is, for example, the overlapping length of the joint between the middle groove of the rim 2 and the spoke 6 can be adjusted, the depth and width of the middle groove of the rim 2 can be adjusted as required, and the protruding position of the spoke 6 can be adjusted as required. Furthermore, the thickness of the rim 2 and the spokes 6 of the variable proper...

Abstract

The invention provides a property-variable vehicle wheel, and belongs to the field of vehicles. The property-variable vehicle wheel comprises a rim, a spoke and a hub. The portion, from an outer ringto an inner ring, of the rim is sequentially provided with an outer-side shoulder flange structure, a middle groove structure and an inner-side shoulder flange structure, wherein the thickness of themiddle groove structure is gradually reduced in the direction from the outer-side shoulder flange structure to the inner-side shoulder flange structure, and is larger than that of the outer-side shoulder flange structure and the inner-side shoulder flange structure; the outer side of the spoke is connected to the hub, and the hub is connected to the inner side of the spoke. According to the property-variable vehicle wheel, through the property-variable structure design, different parts of the vehicle wheels meet different design requirements, and thus the vehicle wheel integrates performance and light weight, and meets the requirement for the lightweight design of vehicles.

Description

technical field [0001] The present application relates to the field of automobiles, in particular to a variable property wheel. Background technique [0002] The wheel is an important part of the car, and it has been subjected to time-varying loads for a long time. The damage of the wheel is mostly fatigue damage, and the spokes and rims are the stress concentration areas of the wheel. Through the variable attribute design of the wheel, the strength of the spokes and rims is increased, and the lightweight design is realized, taking into account the requirements of strength and lightweight. [0003] The wheels mainly bear the weight of the car body and passengers during the driving process of the car. The wheels play an important role in the driving safety and stability of the vehicle, so the quality requirements for the wheels are getting higher and higher. The junction of the spokes and the rim in the wheel must continuously bear the alternating torque, and must have suffi...
