Abstract
The utility model belongs to the field of tubeless wheels for automobiles and in particular relates to a single side double-convex-hump wheel. The single side double-convex-hump wheel is characterized in that an inner convex hump and an outer convex hump are arranged on the same side of a bottom groove of a rim, wherein the inner convex hump is located on the rim at the 5-50mm position on the inner side of a fixedly connecting part of the rim and a spoke, and the outer convex hump is arranged on the rim on the outer side of an inflating valve. The single side double-convex-hump wheel has the advantages of being simple in structure, high in strength and capable of improving fatigue limit of the rim and service life and reducing cost.
Description
Technical field: the utility model belongs to automobile and uses the inner tube-free wheel field, is specifically related to a kind of one-sided biconvex peak wheel.
Background technology: at present, existing inner tube-free wheel, the wheel rim of the inboard at wheel rim and the affixed position of spoke are flat segment structures; Because wheel rim and spoke are fixed on one through welding, and welding can make the material at this position blue crisp phenomenon occur, and material is caused damage; In use, the material in blue crisp district at first can reach fatigue limit and broken phenomenon occur, in order to increase its intensity; Can only guarantee through adopting the way that increases wheel rim thickness; This structure exists the intensity of wheel rim and spoke junction wheel rim low, and fatigue life is short, the shortcoming that the wheel cost is high.
Summary of the invention: the purpose of the utility model provides a kind of simple in structure, and intensity is high, in the service life that can improve the fatigue limit and the wheel of wheel rim, can reduce the one-sided biconvex peak wheel of wheel cost.
The technical scheme of the utility model is: a kind of one-sided biconvex peak wheel, comprise wheel rim and spoke, and it is characterized in that: be provided with convex peak and evagination peak in the same side of wheel rim kerve.Wherein, described convex peak position is on the wheel rim at wheel rim and inboard 5-50mm place, the affixed position of spoke, and the evagination peak is on the wheel rim in the tire tube valve outside.
Owing to adopt technique scheme, under the situation that does not influence wheel normal mounting and use, on the wheel rim kerve in wheel rim and the spoke inboard, affixed position and the outside, be provided with convex peak and evagination peak; Can make the stressed balanced more of wheel rim, the fatigue life of improving wheel rim, reduce the stressed of the blue crisp district of wheel rim; Thereby can reduce the thickness of wheel rim, reduce the weight of wheel, and tire tube valve is positioned at inboard, evagination peak; Can protect it not come to harm, improve the life-span of tire tube valve.Thereby having simple in structurely, intensity is high, the service life that can improve fatigue limit and the wheel of wheel rim, reduction wheel cost advantage.
Description of drawings: come the technical scheme of the utility model is explained further details below in conjunction with accompanying drawing and specific embodiments.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment: with reference to accompanying drawing, a kind of one-sided biconvex peak wheel comprises wheel rim 1 and spoke 2, is provided with convex peak 3 and evagination peak 4 in the same side of wheel rim 1 kerve; Described convex peak 3 is positioned on the wheel rim at wheel rim 1 and inboard 5-50mm place, spoke 2 affixed positions, and evagination peak 4 is on the wheel rim in the tire tube valve outside.
Claims (2)
1. an one-sided biconvex peak wheel comprises wheel rim (1) and spoke (2), it is characterized in that: be provided with convex peak (3) and evagination peak (4) in the same side of wheel rim (1) kerve.
