Abstract

The utility model relates to an integrated wheel, comprising a spoke and a rim which are made of steel plates and are coaxially combined with each other through welding. The utility model is characterized in that the diameter of the outer edge of the spoke is larger than the outer diameter of the no-flange end of the rim and is equal to the outer diameter of the flange end of the rim, and the no-flange end of the rim and the inner side face of the spoke are oppositely welded and combined in 360 DEG. The utility model has the advantages that the integrated wheel has integrated shape and the effect of the integrated surface of an aluminum alloy wheel, enhances the head radiation and shock resistance when the integrated wheel is braked and simultaneously has low production cost, and therefore, the utility model can satisfy the automobile manufacturers and customer's requirements for the light weight, low cost and good durability of the wheel.

Description

Steel wheel with integral type appearance

The utility model relates to a kind of wheel, relates to a kind of integral type wheel specifically.

The existing wheel that is used on the vehicle all includes spoke and wheel rim two parts, but two kinds of versions are arranged.Structure that a kind of wheel has split type (promptly by two parts be combined into), the edge of described spoke stretch into the internal perisporium of wheel rim and by the solder bond one, the intensity of its axial shock resistance distortion can be under some influence; Alternative wheel has one-piece construction, and it is to use the aluminum alloy materials whole cast, and its spoke and wheel rim are combined into one, so good looking appearance, but its manufacturing process is complicated and the manufacturing cost height.

Therefore, the purpose of this utility model provides a kind of low cost of manufacture, has the integral type wheel than high impact-resistant deformability and good looking appearance.

For achieving the above object, integral type wheel of the present utility model comprises: pressure-formed spoke of steel plate and wheel rim, they is characterized in that by combining the outward flange diameter of described spoke equals the bead end external diameter of wheel rim greater than the external diameter of the no bead end of described wheel rim with welding coaxial line; The relative 360 ° of solder bond of the no bead end of wheel rim with the medial surface of spoke.

The steel plate that wheel of the present utility model adopted is a kind of high strength low alloy steel material; The outer peripheral wall thickness of described spoke is greater than described wheel rim wall thickness.

Adopt said structure of the present utility model, owing to replaced the front portion of wheel rim with the spoke outward flange, 360 ° of welds are on the spoke medial surface, therefore have the integral type moulding, make steel wheel only need decoration seldom just can obtain to be rich in sporty integral type appearance; Owing to increased dissipating area, therefore the heat that is produced when glancing impact can distribute more running has improved the heat dispersion of glancing impact; Because the weld of wheel rim and spoke is invisible, the pattern of moulding can more be full of variety simultaneously; Owing to the front portion that has replaced wheel rim with the thicker spoke edge of material, improved wheel is resisted edge deformation when running into road shocks ability; Its weight is almost with the identical of corresponding aluminum-alloy wheel but its price only is 30% to 50% of an aluminum-alloy wheel price.In a word, integral type wheel of the present utility model has the effect of the whole face of aluminum-alloy wheel, and can satisfy automaker and the client is in light weight to wheel, cost is low and durability is good requirement.

Specifically describe below in conjunction with the integral type wheel of accompanying drawing, so that clearlyer understand the purpose of this utility model, characteristics and advantage the utility model one preferred embodiment.

Fig. 1 is a kind of structural representation of analysing and observe of existing steel wheel;

Fig. 2 is the cutaway view of the integral type wheel made of a kind of existing aluminum alloy materials;

Fig. 3 is the front view of the integral type wheel of the utility model one preferred embodiment;

Fig. 4 is the cutaway view of being got along the A-A line of Fig. 3.

Fig. 1 and 2 illustrates the structure of two kinds of traditional wheels.Shown in Figure 1 is a kind of wheel of split-type structural, the edge 3 of the pressure-formed spoke 1 of steel plate stretches into the internal perisporium of the pressure-formed wheel rim 2 of steel plate and passes through the solder bond one, to go up when move on the road surface with car be to contact the road surface by the tire that is installed on wheel rim bead 4 peripheries diametrically when wheel is installed on axle drive shaft (not shown) by spoke 1, and corresponding bead easy deformation when axially being subjected to impulsive force touching hard obstacle; Alternative wheel has one-piece construction as shown in Figure 2, and it is to use the aluminum alloy materials whole cast, and its spoke part 1 and wheel rim part 2 are combined into one thereby good looking appearance, but its manufacturing process is complicated and the manufacturing cost height.

The utility model keeps the advantage of the whole face of aluminum-alloy wheel, but the spoke that steel plate is made into by welding is in the same place with the wheel rim mortise.Shown in Fig. 3 and 4, integral type wheel of the present utility model comprises: spoke 1 that steel plate is pressed into and wheel rim 2, the outer diameter D of the outward flange 5 of spoke equals the outer diameter D 2 of the bead end 7 of wheel rim 2 greater than the outer diameter D 1 of the no bead end 6 of wheel rim 2, the no bead end 6 of wheel rim welds and combines with making spoke 1 and wheel rim 2 coaxial lines and be integral for relative with the medial surface of spoke 360 °.The steel plate that wheel of the present utility model adopted is a kind of high strength low alloy steel material; The wall thickness of spoke 1 outward flange 5 is suppressed greater than the wall thickness of wheel rim 2.

As mentioned above, because with the enlarged diameter of spoke 1, replaced the front portion of wheel rim with spoke outward flange 5, and by along spoke medial surface and wheel rim 2 no bead end 6 relative 360 ° be welded into integral body, therefore have the integral type moulding, can reach same aesthetic with the whole face of aluminum alloy.
