The specific embodiment
As shown in Figure 3, its cross section of this steel inner tube free automotive wheel equal strength wheel rim comprises inboard wheel rim 4, inboard tire bead seat 5, rim gutter 6, linear portion 8, outboard tire bead seat 9 and the outer rim 10 that links to each other successively.The cross section at the junction 13 of junction 11, outer rim and the outboard tire bead seat of inboard wheel rim and inboard tire bead seat and three positions such as junction 12 of outboard tire bead seat and linear portion is thicker, and the cross section at all the other positions is thinner.
As shown in Figure 3, the cross section of this steel inner tube free automotive wheel equal strength wheel rim from wall thickness to wall thin place, be all slick and sly transition gradually to the wall thickness place from wall is thin.
As calculated and the experiment, on wheel rim, the junction 13 of junction 11, outer rim and the outboard tire bead seat of inboard wheel rim and inboard tire bead seat and the junction of outboard tire bead seat and linear portion 12 suffered load maximums, therefore, this three places rim cross-section design gets the thickest.Proper extension linear portion 8 can play the bearing strength of strengthening outboard tire bead seat 9, and the weld strength of enhancing and spoke 2 under the identical situation of spoke offset distance, can reduce the length of spoke and wheel rim joint portion linear portion.
The equal strength wheel rim of this different cross section thickness can come machine-shaping by the shear spinning technology.By the flow harden effect of shear spinning, the intensity of rim material is greatly improved.Like this, under the prerequisite of working profile curve, except the position of thickening, the cross section at all the other positions can be done thinlyyer than general tubeless tire rim outside guaranteeing wheel rim.The wheel made from this equal strength wheel rim is not only more in light weight but also fatigue resistance is high than the wheel made from the equal thickness wheel rim, can satisfy that automobile quantizes wheel light and the requirement of safety.
Equal strength wheel rim with 22.5 * 8.25 inner tube free steel wheels is an example, its thickness by Fig. 3 from left to right in axial direction rule be such: outer rim 10 is 6mm; The junction 13 of outer rim and outboard tire bead seat is 8mm; Outboard tire bead seat 9 is thinned to 5.6mm gradually by 8mm; Near linear portion 8 first three/place is increased to 8mm again gradually, this is because the result that the extension of linear portion 8 and outboard tire bead seat 9 intersect, its effect is the weld strength and the bearing strength of enhancing and wheel rim, reduces the length of spoke and wheel rim joint portion linear portion, saves spoke material; Thickness is thinned to the 5.6mm at linear portion 8 places gradually then; Rim gutter 6 keeps the 5.6mm thickness, up to the junction of the inboard tire bead seat 5 on the right; Inboard tire bead seat 5 is increased to 8mm gradually with junction 11 thickness of inboard wheel rim 4; The thickness of inboard wheel rim 4 also is 6mm.
