Abstract

The utility model relates to a wheel rim for an engineering mechanic vehicle. The wheel rim comprises a wheel rim base. The both sides of the wheel rim base are respectively provided with a tyre base and a grooved ring. The side of the tyre base is connected with the wheel rim. The wheel rim is provided with spokes. The utility model is characterized in that the wheel rim base is provided with an enforcing groove; the enforcing groove wall thickness is smaller than the thickness of the tyre base and grooved ring. Historically, the wheel rim base of the wheel rim is a straight steel ring, which is made from steel plates with different thicknesses according to the load capacity. This is a common sense in the wheel making industry. However the utility model processes the straight steel ring in to a thinner corrugated or straight enforcing groove. Because of the advanced processing method, the wheel rim base is changed in the material grains, enhanced in the material strength, thus lowered in the thickness, boasted in the strength of the wheel rim base, reduced in the usage of the used materials and lowered in the wheel cost.

Description

A kind of rim for automobile wheel of engineering machine vehicle

Technical field

The utility model relates to a kind of rim for automobile wheel of engineering machine vehicle, particularly a kind of rim for automobile wheel that has the engineering machine vehicle of intensity groove at the outside face or the inside face of rim base.

Background technology

The rim for automobile wheel bottom profile of present various engineering machine vehicles is straight substantially, and except that groove circle part, the each several part of rim hase all is an equal thickness.If reach the purpose that improves whole rim hase intensity, will the consumption of material be increased, Master Cost and productive costs are increased.

Summary of the invention

The purpose of this utility model provides a kind of rim for automobile wheel of later-model engineering machine vehicle, it can overcome the existing in prior technology shortcoming, can under original material thickness unmodified situation, increase substantially the intensity of wheel rim, reduce the material usage and the cost of wheel rim simultaneously significantly.

The purpose of this utility model is achieved in that it comprises rim base, is respectively equipped with wheel rim and groove circle at the two ends of rim base, is provided with spoke in the wheel rim, it is characterized in that the rim base in the spoke both sides is provided with the intensity groove.

Above the intensity groove of said rim base be to adopt the mode of shear spinning that the rim base of spoke both sides is made thin bellows segment or flat segments, the flat segments notch promptly can be inside, also can be outside.

Since the dawn of human civilization, the rim base of engineering machine vehicle wheel all is straight steel ring, does not all have the intensity groove, just uses the steel plate manufacturing of different-thickness according to the difference of load-carrying capacity.This has become common recognition in the wheel manufacturing.And the utility model is processed into the thin corrugated or the intensity groove of straight slot shape with the rim base of straight steel ring.Owing to adopt advanced spinning processing method, the crystal grain of rim base material is changed, material is improved its intensity through flow harden.Even therefore reduced thickness, the intensity of rim base also can be greatly enhanced, and the use amount of material is reduced, and has reduced the cost of wheel.

Description of drawings

Fig. 1-Fig. 5 is the side sectional view of specific embodiment of the present utility model five types.

The specific embodiment

With reference to Fig. 1, the 1st, wheel rim, what join with wheel rim 1 is

bead seat

2, and 5 among the figure shown in the right-hand member is groove circles, promptly is rim base 3 between groove circle and bead seat, and as seen from the figure, the centre of rim base is welded with spoke 4.The inventive point of present embodiment is that rim base 3 adopts the method flow forming of shear spinning, and wall thickness is thin than two ends, and is corrugated.In addition, as shown in the figure, the position of welding spoke is in order to prevent to weld the influence of annealing to intensity, so still adopt thicker wall thickness in the middle of rim base.

With reference to Fig. 2,7 is wheel rim, and as seen from the figure, wheel-rim shape illustrated in figures 1 and 2 is different, and this formulates according to the needs that use, and other various required form can also be arranged.5 is groove circles among the figure, and what be connected with wheel rim 7 is bead seat 2.Be connected between groove circle and the bead seat is rim base 6.As seen from the figure, the rim base 6 of present embodiment is the straight slot shape.Because adopt the method processing of shear spinning, its intensity is higher, so its thickness is thinner than the bead seat 2 and the groove circle 5 at two ends, the notch of its intensity groove is at the outside face of rim base 6.On the position of centre welding spoke 4, adopt thicker wall thickness equally, to remedy the influence that welding annealing makes strength degradation cause the wheel rim intensity.

Structure shown in Figure 3 and the structure difference shown in Fig. 2 be rim base 6 the notch of intensity groove be provided in a side of the inside face of rim base.

The structure difference of Fig. 4 and structure embodiment illustrated in fig. 5 and first three embodiment is: position and its both sides of welding spokes 4 also can be condition of equivalent thickness in the middle of the rim base 6.The notch of intensity groove can be to be located at outside face as shown in Figure 4 in addition, also can be located at inside face as shown in Figure 5.

As shown in the figure, wheel rim can adopt 1 shown in the figure and 7 two kinds of different shapes, can exchange between difform wheel rim 1 and the wheel rim 7.

Claims

1, a kind of rim for automobile wheel of engineering machine vehicle, it comprises rim base, be respectively equipped with bead seat and groove circle at the two ends of rim base, the end of bead seat is connected with wheel rim, be provided with spoke in the wheel rim, it is characterized in that rim base is provided with the intensity groove, the wall thickness of intensity groove is less than the thickness of bead seat and groove circle.

2,, it is characterized in that the intensity groove of rim base is a corrugated according to the rim for automobile wheel of the said engineering machine vehicle of claim 1.

3,, it is characterized in that the intensity groove of rim base is to rise as high as the banks according to the rim for automobile wheel of the said engineering machine vehicle of claim 1.

4,, it is characterized in that at the wall thickness of the position of rim base welding spoke wall thickness greater than both sides intensity groove according to the rim for automobile wheel of the said engineering machine vehicle of claim 1.

5,, it is characterized in that the intensity groove can be located at the inside face or the outside face of rim base according to the rim for automobile wheel of the said engineering machine vehicle of claim 3.
