Description
Technical field
The utility model relates in the automotive wheel manufacturing, a kind of geometry of steel inner tube free automotive wheel.
Background technology
Lightweight is the needs that automobile develops to " energy-conservation, reduction of discharging " direction, and the quality that alleviates wheel is to realize one of automobile weight-saving important measures, and uses the wheel than small dimension to replace the wheel of big specification can alleviate the quality of wheel effectively.The inwall press fit arrangement and the weld together of the cylindrical of the linear portion of common steel inner tube-free wheel spoke and the mounting of wheel rim.The wheel of this structure is owing to the inner space deficiency, if use the wheel that replaces big specification than the wheel of small dimension, its inside does not have enough drg installing spaces, and has influence on use.Japanese Patent " spy opens flat 11-278001 " proposes a kind of car wheel structure, in order to increase inside wheel the space of drg is installed, spoke is arranged on bead seat one side that does not have mounting, in order to reduce the influence of weld seam to the bead seat surface quality, increase the intensity of this one and be convenient to press fit arrangement, cross section thickening with bead seat forms a trigonum.The wheel of this structure has solved effectively in the problem of using drg requisite space deficiency when replacing the wheel of big specification than the wheel of small dimension.But the wheel rim of the wheel of this kind structure need be with special-purpose rolled section steel, and operations such as longitude circle circle/welding process, and material source is restricted, and weld seam is curve, clears up difficultly, influences the wheel surface quality.
Summary of the invention
The purpose of this utility model is the geometry that proposes a kind of steel inner tube free automotive wheel, and its wheel rim can be rolling with steel plate or steel band, can use the wheel that replaces big specification than the wheel of small dimension again, to satisfy automobile to the requirement of wheel weight-saving.
This steel inner tube free automotive wheel comprises wheel rim and spoke, and wherein wheel rim comprises revolver edge, left bead seat, rim gutter left side wall, rim gutter, rim gutter right side wall, mounting, right bead seat and revolver edge.The spoke of this steel inner tube free automotive wheel is installed in left bead seat one side that does not have mounting of wheel rim, the weld seam that engages between the inwall pressing and the weld together of the cylindrical of the linear portion of spoke and the left bead seat of wheel rim, spoke and wheel rim is between left bead seat and adjacent with it rim gutter left side wall.
The wheel rim of this steel inner tube free automotive wheel can be with steel plate or steel band, longitude circle circle/welding/spinning/roll operations such as shape to process, material source is extensive, weld seam is a straight line, cleaning easily, the wheel surface quality is good, and rim material is through spinning with after rolling shape operation cold-working processing, and intensity obtains bigger raising.This steel inner tube free automotive interior is that drg leaves enough spaces, can be used for replacing the common wheel of big specification, can alleviate the quality of wheel greatly,
Description of drawings
Fig. 1 is the geometry of common steel inner tube-free wheel, wherein:
1 wheel rim, 2 spokes, 3 weld seams;
Fig. 2 is Japanese Patent " spy opens a flat 11-278001 " wheel geometry, wherein:
4 wheel rims, 5 spokes, 6 weld seams, 5a are the linear portion of spoke;
Fig. 3 is the geometry of the steel inner tube free automotive wheel that the utility model proposes, wherein:
7 wheel rims, 8 spokes, 9 weld seams, 10 valve holes, 11 drgs;
Fig. 4 is the partial enlarged drawing of Fig. 3.
The specific embodiment
Be described further below in conjunction with accompanying drawing.
Common steel inner tube-free wheel is as shown in Figure 1: wheel rim 1 partly is made up of revolver edge 1a, left bead seat 1b, mounting 1c, rim gutter left side wall 1d, rim gutter 1e, rim gutter right side wall 1f, right bead seat 1g and right wheel rim 1h etc.The internal diameter press fit arrangement of the external diameter of the linear portion 2a of spoke 2 and the mounting 1c of wheel rim 1 also becomes an inner tube-free wheel at weld seam 3 places with its weld together.The wheel of this structure is owing to the inner space deficiency, if use the wheel that replaces big specification than the wheel of small dimension, its inside does not have enough drg installing spaces, and has influence on use.
The car wheel structure that Japanese Patent " spy opens flat 11-278001 " proposes is as shown in Figure 2: wheel rim 4 partly is made up of revolver edge 4a, left bead seat 4b, rim gutter left side wall 4c, rim gutter 4d, rim gutter right side wall 4e, mounting 4f, right bead seat 4g and right wheel rim 4h etc.This wheel is arranged on spoke 5 bead seat one side that does not have mounting; In order to reduce the influence of 6 pairs of left bead seat 4b surface qualitys of weld seam, increase the intensity of this one and be convenient to press fit arrangement, with the cross section thickening of left bead seat 4b, form the trigonum of A portion.The wheel rim of the wheel of this structure needs to make with special-purpose shaped steel.
A kind of steel inner tube free automotive wheel that the utility model proposed as shown in Figure 3, comprise wheel rim 7 and spoke 8, wherein wheel rim comprises revolver edge 7a, left bead seat 7b, rim gutter left side wall 7c, rim gutter 7d, rim gutter right side wall 7e, mounting 7f, right bead seat 7g and right wheel rim 7h.Spoke 8 is installed in left bead seat 7b one side that does not have mounting of wheel rim, the weld seam 9 that engages between inwall pressing and the weld together of the cylindrical of the linear portion 8a of spoke and the left bead seat 7b of wheel rim, spoke and wheel rim is at the intersection of left bead seat 7b and adjacent with it rim gutter left side wall 7c.
As shown in Figure 3 and Figure 4, interfere, can also one section round peak C be set at the left bead seat 7b of wheel rim and the intersection of rim gutter left side wall 7c for fear of weld seam 9 and valve hole 10.This circle peak C prevents tire effect to the rim gutter landing when air pressure is not enough in addition.For the ease of spoke 8 press fit arrangement with wheel rim 7, can also be on the bead seat 7b of a wheel rim left side little triangular-section B be set with the joint of spoke 8, cooperate with cylinder to replace cone match, the axial length of the fitting surface of itself and spoke linear portion 8a is greater than 6mm.
The utility model steel inner tube free automotive wheel inner space is big, can hold the drg of big specification wheel, thereby can replace the common wheel of big specification, can alleviate the quality of wheel greatly.Be the position of drg among Fig. 3 shown in 11.With specification is that the utility model wheel of 6.75 * 19.5 is an example, available it to replace specification be 7.50 * 22.5 common wheel.The quality of every 7.50 * 22.5 wheel is 34 kilograms approximately, and about 28 kilograms of the quality of every 6.75 * 19.5 of the utility model wheel, the effect that alleviates quality is fairly obvious.
