Abstract
The utility model discloses light wheel rim section steel. The light wheel rim section steel comprises at least one segment of steel plate used for manufacturing a wheel rim. The two surfaces of the steel plate are respectively provided with multiple arc-shaped projections. The arc-shaped projections on the two surfaces are symmetrical with respect to the longitudinal central plane of the steel plate. According to the scheme, the multiple arc-shaped projections are respectively formed through rolling onto the two surfaces of the steel plate of the section steel used for manufacturing the wheel rim and the arc-shaped projections are respectively corresponding to the force bearing parts on the wheel rim section steel, so that the projections serve as reinforcing ribs on the tubeless wheel rim. The arc-shaped projections are symmetrical with respect to the longitudinal central plane of the steel plate so that the two sides of the steel plate in the force bearing parts are both thickened. Therefore, in comparison with a wheel rim made of section steel formed by rolling a steel plate with an identical material thickness, the wheel rim made of the present section steel is high in strength. As the material thickness of the section steel needed for manufacturing the wheel rim with identical strength is reduced, the wheel rim manufacture cost is saved.
Description
Technical field
The utility model relates to a kind of for making the light-duty rim shaped steel of wheel.
Background technology
Wheel rim is to coordinate the wheel part of support tire with tire, and it comprises the parts such as wheel rim, bead seat and bottom land, normally by one flat plate steel, by roll extrusion, is formed.In rolling process, all crooked positions and the thickness of stress point all equate, so sweep and stress point can stretch and attenuation in the process of extruding, in stressed attention, easily cause the infringements such as cracking (being commonly called as " fried large limit "), cause the vehicle in travelling that catastrophic consequence occurs, therefore in order to increase the intensity of wheel rim, the thicker steel plate flow forming of normal employing, cost is high, weight is large, the wasting of resources.
Utility model content
It is a kind of for making the light-duty rim shaped steel of wheel that the purpose of this utility model is to provide, high to solve the cost of existing wheel rim, the problem that weight is large.
For achieving the above object, the scheme that the utility model adopts is: light-duty rim shaped steel, comprise that at least one section for making the steel plate of wheel rim, on two faces of described steel plate, be respectively equipped with some arc convex, the arc convex on two faces is symmetrical structure along longitudinal center's face of steel plate.
Described arc convex is separately positioned on wheel rim two ends, wheel rim bead seat and rim junction, the bottom land circular arc place of wheel rim.
On described light-duty rim shaped steel, comprise that 2-5 section is for making the steel plate of wheel rim, described light-duty rim shaped steel is made by the roll extrusion of monoblock steel plate.
On described steel plate, corresponding to wheel rim and described arc convex place, be provided with thickening.
In this programme, on two faces of steel plate of making rim shaped steel, rolling has some arc convex respectively, and this arc convex corresponds respectively to the part of the force on rim shaped steel, and this projection plays reinforced rib on tubeless rim.Because this arc convex is symmetrical structure along longitudinal center's face of steel plate, both sides at part of the force steel plate all thicken, therefore, the wheel rim of making for the section bar of the thick steel plate flow forming of identical material, its intensity is high, when making the wheel rim of same intensity, need thick reduction of material of section bar, saved wheel rim manufacturing cost.
Accompanying drawing explanation
Fig. 1, be light-duty rim shaped steel cross sectional drawing;
Fig. 2, be the cross-sectional plane corresponding diagram of light-duty rim shaped steel cross-sectional plane and wheel rim.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, light-duty rim shaped steel 5 of the present utility model, on this light-duty rim shaped steel 5, comprise that at least one section for making the steel plate of wheel rim, on two faces of described steel plate, be respectively equipped with some arc convex, the arc convex on two faces is symmetrical structure along longitudinal center's face of steel plate.
As shown in Figure 2, light-duty rim shaped steel 5 of the present utility model contrasts schematic diagram with the cross-sectional plane of the wheel rim being formed by its rolling, described arc convex is arranged at respectively two ends, wheel rim bead seat 3 and rim 1 connecting portion of the wheel rim 1 of corresponding wheel rim, on a face of the steel plate at bottom land circular arc 2 places, formed concavo-convex reinforced rib separately like this on a surface of section bar steel plate.Light-duty rim shaped steel is made by the roll extrusion of monoblock steel plate, can comprise that the multistages such as 1 section, 2 sections, 3 sections, 4 sections or 5 sections are for making the steel plate 5 of wheel rim on a light-duty rim shaped steel, and shaped steel is made by the roll extrusion of monoblock steel plate.In order to improve the intensity of the wheel rim of rolling, can be at the thickness of wheel rim 1 and arc convex part increase steel plate.
The wheel rim of making of rim shaped steel section bar of the present utility model, it is at wheel rim, bead seat fillet, and bead seat and the force parts such as fillet of bottom land 4 connecting portions and the thickness of stressed sweep have obtained increase, meanwhile, have reduced the thickness of non-stress face.Especially, on two faces of the steel plate of light-duty rim shaped steel, be all provided with arc convex, make like this in the situation that gaining in strength total weight by decline, the wheel rim of making for the wheel rim section bar of flat plate steel compacting, has improved intensity, has extended product service life, reduced cost, because wheel rim is light, its wheel of making is also light, can save vehicle oil consumption in motion simultaneously.
Claims (4)
1. a light-duty rim shaped steel, comprises that at least one section for making the steel plate of wheel rim, it is characterized in that, on two faces of described steel plate, is respectively equipped with some arc convex, and the arc convex on two faces is symmetrical structure along longitudinal center's face of steel plate.
2. according to light-duty rim shaped steel claimed in claim 1, it is characterized in that, described arc convex is separately positioned on wheel rim two ends, wheel rim bead seat and rim junction, the bottom land circular arc place of wheel rim.
