Abstract
The invention discloses an improved J-shaped wheel rim. The thickness of the outer wheel flange is larger than or equal to 6mm and smaller than 11mm, and the smallest thickness from the front window face to a bead seat is larger than or equal to 5mm. The peak highest point is the two-section arc tangency demarcation point, and the radius of the side arc of the peak close to the bead seat is in a range of 8mm to 11.5mm. The radius of the side arc of the peak close to the central line of the rim is larger than 4mm and smaller than the radius of the side arc of the peak close to the bead seat, and an inner wheel flange is arranged in a groove for preventing falling off of a balance weight.
Description
Technical field
The present invention relates to a kind of automotive parts, relate in particular to aluminum-alloy wheel.
Background technology
Along with improving constantly of automobile appearance and lightweight requirements, as the wheel appearance and modeling of a car load outward appearance part and wheel lightweight requirements also more and more higher.For outer rim, because balance block clamping is in front face of wheel, affect the appearance of wheel, so current most medium-to-high grade wheel does not adopt, and mainly adopt the front rim construction without wheel lip.For hump, what aluminum-alloy wheel the most often adopted is peace peak, circle peak.For inner side wheel rim, normal and outer rim is symmetrical.
In aluminium alloy wheel rim design process, need to use home made article standard according to wheel.These product standards are to flange thickness, and hump size all has clear stipulaties.Be not less than 11mm for GB/T 3487-2005, J type rim thickness, the radius at circle peak is 8mm to 11.5mm, inner rim relative dimensions and outer rim about wheel rim center line symmetry, as shown in Figure 1.Because wheel rim thickness is limited by wheel strength and molding mode, add the restriction to wheel rim and hump size of aforementioned various countries product standard, make aluminium alloy wheel rim lightweight be in bottleneck, inner rim and foreign steamer symmetric design make inner side clip on balance block have the risk that comes off.
In order to meet the requirement of wheel weight-saving, the risk and reduction inner side clip on balance block comes off, the above problem of rim for automobile wheel needing research and development to improve is solved.
Summary of the invention
Technical scheme of the present invention is: the J type rim for automobile wheel of improvement, and outer rim thickness is set to be more than or equal to 6mm, be less than 11mm, and front window actinal surface is more than or equal to 5mm to bead seat place minimum thickness.Outer rim circle peak part is made up of tangent two sections of circular arcs, circle peak vertex is two sections of tangent train spacing points of circular arc, near bead seat side arc radius according to product standard, be set to 8mm-11.5mm, meet the minimum value of dress tire requirement near wheel rim center line side arc radius, be set to be greater than 4mm and be less than near bead seat side arc radius simultaneously.
Inner rim arranges groove, to reduce clip on balance block slip-off preventing risk.Depth of groove is 0.5mm-2mm, and groove radius is 3mm-6mm.
The present invention is on the basis meeting tire assembling, wheel strength requirement, and to outer rim, 5 of peak is not justified in clamping balance block and outside
°deep trouth J type rim structure, is proved by actual production, can effective loss of weight, breaks through wheel rim light-weight design bottleneck, reduces inner rim clip on balance block simultaneously and to come off risk.

Detailed description of the invention
As in Figure 2-4, the J type rim for automobile wheel that the present invention improves, outer rim thickness is more than or equal to 6mm, is less than 11mm, and front window actinal surface is more than or equal to 5mm to bead seat place minimum thickness.
Outer rim circle peak part is made up of tangent two sections of circular arcs, circle peak vertex is two sections of tangent train spacing points of circular arc, be set to 8mm-11.5mm near bead seat side arc radius, the radius near wheel rim center line side circular arc is greater than 4mm, is less than near bead seat side arc radius.
Inner rim arranges groove, to reduce clip on balance block slip-off preventing risk.As shown in Figure 4, depth of groove is 0.5mm-2mm, and groove radius is 3mm-6mm.
The J type rim wheel that the present invention improves, is not limited to the content described in content of the present invention and detailed description of the invention, inspires and the rim structure mode of acquisition, all fall into protection scope of the present invention according to content of the present invention.
