The specific embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to the accompanying drawings the specific embodiment of the present utility model is elaborated.Herein, same reference numerals is represented the same composition part.
As shown in Figures 1 to 4, wheel of the present utility model comprises wheel rim and spoke.Described wheel rim 1 is the steel wheel rim.Described spoke 2 is the aluminum alloy spoke, and promptly spoke 2 is formed by aluminium alloy casting.Described wheel also comprises circular connector 3.Described circular connector 3 is arranged between described spoke 2 and the described wheel rim 1.Particularly, described circular connector 3 has and described spoke 2 inboard flat part 32 that links to each other and the kinks 31 that link to each other with described wheel rim 1 inner peripheral surface.The circular-arc inner peripheral surface crimping of described kink 31 and wheel rim 1.And described flat part 32 and described spoke 2 connect by bolted; Described kink 31 is fixing with described wheel rim 1 welding.
In a preferred embodiment of the present utility model, described flat part 32 is fastening by 14 bolts 5 of circumferential well-distributed and 14 nuts 4 with described spoke 2, and described nut 4 and described flat part 32 are fixed by spot welding.As illustrated in fig. 1 and 2, described spoke 2 have 7 spokes 21 and with the cover plate 22 of described wheel rim 1 coupling.Described bolt 5 and described nut 4 are arranged on the cover plate 22 between each spoke 21.In Fig. 2, described circular connector 3 is blocked by described cover plate 22 and is invisible.Particularly, be furnished with 2 bolts 5 and corresponding two nuts 4 on the cover plate 22 between the adjacent spoke 21.Certainly, also can arrange more screw bolt and nut.
In a specific embodiment of the present utility model, steel wheel rim 1 adopts four sections weldering form welding fixing with circular connector 3 one sides.Wherein, circular connector 3 also is a steelwork.The spoke 2 of aluminium alloy casting is connected by high strength bolt 5 with the opposite side of circular connector 3, and is terminal fastening with nut 4.And, for locking, nut 4 and circular connector 3 spot welding are fixed.
As shown in Figure 1 and Figure 2, circular connector 3 one sides are the arc structures that adapt with wheel rim 1, and the side that its top and spoke 2 are mated adapts and guarantees its quality of fit.That is described kink 31 is fitted with the inner peripheral surface of described wheel rim 1, and described flat part 32 is fitted with the inboard of described spoke 2.
In a preferred embodiment of the present utility model, described wheel is an inner tube-free wheel.Its reason is, that inner tube-free wheel has is simple in structure, in light weight, fuel saving, thermal diffusivity is good, driving safety is high advantage.
As mentioned above, the utility model provides a kind of wheel, and it is made of the wheel rim and the spoke of wheel respectively two kinds of different materials.Particularly, wheel rim is a steel, and spoke is an aluminium alloy castings.In the assembly technology of wheel, at first, this rim for automobile wheel with adopt same material circular connector one side to adopt four sections weldering forms welding with wheel rim therebetween, utilize 14 high strength bolts that the aluminum alloy spoke is connected with the circular connector opposite side then, terminal fastening with nut, last spot welding nut and attaching parts are in order to avoid bolt looseness.Rim and spoke adopts high strength bolt to connect technology and is combined as a whole, and has the effect that buffering is decomposed impulsive force.Whole car wheel structure precision height, dynamic balance are good, well spoke moulding simultaneously is changeable attractive in appearance for elasticity and supporting effect.
Because the spoke of wheel of the present utility model adopts aluminium alloy casting, can guarantee that it has higher accuracy of manufacture by machinework, its integral structure radial beat eccentricity and axial runout amount are reduced, dynamic balance is good.Its moulding of as cast spoke is unrestricted to realize advantages such as the spoke moulding is changeable, attractive in appearance.Simultaneously, rim and spoke adopts high strength bolt to connect.Like this, can make wheel have the effect that buffering is decomposed impulsive force, advantage such as have simultaneously that shock absorption is good, elasticity and supporting effect are good, and on manufacturing process, can reduce the input of equipment and mold, thus the input of minimizing cost makes its cost lower.
The spoke of wheel adopts aluminium alloy casting, can guarantee that it has higher accuracy of manufacture by machinework, makes its integral structure warp-wise jerk value and axial runout amount reduce more.Lighter from weight than steel wheel, thus more fuel-efficient.Its moulding of as cast spoke is unrestricted to realize advantages such as the spoke moulding is changeable, attractive in appearance.And the rigidity of this wheel and intensity are carried out finite element analysis as can be known by the finite element analysis software ANSYS of U.S. ANSYS company, and is all better than steel wheel and aluminum-alloy wheel.
In wheel of the present utility model, the circular connector that is connected with spoke has played the bearing capacity that decomposes radially, and like this, radially bearing capacity just can not carried by spoke fully.Therefore, dynamic balance of wheel is just fine.Particularly, rim and spoke adopts 14 high-intensity bolted connections, and bearing capacity radially just is distributed on 14 high-intensity bolts, has played buffering and has decomposed the effect of impulsive force, thereby made shock absorption, elasticity and the supporting effect of wheel more superior.In addition, on manufacturing process, can reduce the input of equipment and mold, thereby reduce the input of cost, make its cost lower, and solved the following problem that existing steel-aluminum wheel exists: the spinning process capacity rating is lower, and labour intensity is bigger, relatively is applicable to trial-production and small batch production.
Those skilled in the art know easily; the above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.Protection domain of the present utility model is determined by claims.
