Abstract
A tubeless profile steel wheel relating to wheel structure is formed by two parts, namely a profile steel wheel rim and spokes. The structure is that: thickness or heave is correspondingly added to section of each turn forced part of the non-tire matching surface of the profile steel wheel rim, particularly an outward raised heave is added on the section of the connection and turn forced part of an arch leg and a tire ring base; and the thickness of the section is correspondingly decreased on the unforced part of the profile steel wheel rim. The utility model can not only reduce the manufacture cost of the tubeless profile steel wheel, but can also improve the work efficiency, and further effectively strengthen the strength of the wheel rim and the wheel, reduce the weight of the wheel and improve the sealing performance of the wheel rim and the tire.
Description
Technical field
The utility model relates to a kind of automobile inner tube-free wheel structure.
Background technology
Inner tube-free wheel is one of important set member of automobile traveling system, and it is made up of wheel rim and two parts of spoke.Wheel rim be the stressed maximum of inner tube-free wheel and with the close-fitting key position of tire, also be the main consumable accessory of inner tube-free wheel.Existing tubeless tire rim is to form through rolling and processing repeatedly with flat board; Flat board because of being subjected to factor affecting such as equipment, mould, technology and material property, causes the rim hase became uneven, especially the obvious attenuation in the force part of respectively turning of rim hase in the rolling process.Its consequence is: in the wheel driving process, as easy as rolling off a log generation distortion in each turning site of rim hase and fracture cause then that gently tire becomes flat, and heavy then whole wheel is scrapped, and causes safety misadventure.Moreover the used specialized equipment price of material for rolling wheel is high and investment is big, and production efficiency is low again, and tooling cost is high.
Summary of the invention
The purpose of this utility model is that for overcoming above-mentioned defective, employing shaped steel wheel rim substitutes the contour roll forming wheel rim, and a kind of inner tube free shaped steel wheel is provided.
Scheme of the present utility model is: under the situation of the contour shape of guaranteeing inner tube-free wheel and tire fitting surface and size conforms national standard, corresponding increase thickness or projection on the cross section of the force part of respectively turning of the non-tire fitting surface of shaped steel wheel rim particularly increase the projection to outer lug on the cross section that is connected the turning force part of the arcuate leg of wheel rim and bead seat; Thickness in corresponding attenuate cross section, the position of shaped steel wheel rim non-stress.
The utility model has the advantages that:
(1), the utility model used be common apparatus, than little with the investment of the used specialized equipment of the inner tube-free wheel of traditional rolling; The processing technology of wheel is simple, and is with short production cycle, and productive costs is low, and the production efficiency height is convenient to tissue and is produced in enormous quantities.
(2), on the cross section of the force part of respectively turning of the non-tire fitting surface of shaped steel wheel rim of the present utility model, increased corresponding thickness or projection, thereby strengthened the intensity of wheel rim and wheel, under strained condition, be not prone to distortion, phenomenon of rupture; The closure of rim for automobile wheel and tire is good, does not become flat, leaks gas.
(3), the utility model attenuate the section thickness at the non-stress position on the non-tire fitting surface of shaped steel wheel rim, thereby alleviated the weight of wheel.
Description of drawings
Fig. 1 is a cross-section cutaway view of the present utility model.
Among the figure: the 1st, the shaped steel wheel rim, the 2nd, spoke, 3,4,5,6,7,8 all is turning force parts of the non-tire fitting surface of the utility model, the 9, the 12nd, arcuate leg, the 10, the 11st, bead seat.
Among the figure: the upper surface in the utility model cross section is the fitting surface of shaped steel wheel rim (1) and tire, and lower surface is the fitting surface of the non-tire of shaped steel wheel rim (1).
The specific embodiment
The utility model is to implement like this, and it is made up of shaped steel wheel rim (1) and (2) two parts of spoke:
Embodiment 1: during steel rolling mill rolling wheel rim shaped steel, under the situation of the contour shape of guaranteeing inner tube-free wheel and tire fitting surface and size conforms national standard, corresponding increase thickness or projection on the cross section of the force part of respectively turning of the non-tire fitting surface of wheel rim shaped steel particularly form the projection to outer lug on the cross section that is connected the turning force part of arcuate leg (9) (12) and bead seat (10) (11); Thickness in corresponding attenuate cross section, the position of wheel rim shaped steel non-stress.Thereafter, wheel rim shaped steel is rolled up circle, is welded into shaped steel wheel rim (1), at last shaped steel wheel rim (1) is become inner tube free shaped steel wheel with spoke (2) field weld.
The arcuate leg of shaped steel wheel rim is connected the cross sectional shape to the projection of outer lug that increases on the cross section of turning site and is set at semicircle shape, crescent shape with bead seat.
Claims (2)
1. inner tube free shaped steel wheel, relate to automobile inner tube-free wheel structure, it is made up of shaped steel wheel rim, spoke, it is characterized in that: certain thickness and the projection of corresponding increase on the cross section of the force part of respectively turning of the non-tire fitting surface of shaped steel wheel rim, be connected the projection that increases on the cross section of turning force part to outer lug with bead seat in the arcuate leg of wheel rim, thickness in corresponding attenuate cross section, the non-stress position of shaped steel wheel rim.
2. by the described inner tube free shaped steel of claim 1 wheel, it is characterized in that: be connected the cross sectional shape that increases on the cross section of turning site in the arcuate leg of shaped steel wheel rim with bead seat and be set at semicircle shape, crescent shape to the projection of outer lug.
