Abstract
In order to solve the problems that a rim structure of a light all-terrain motorcycle in the prior art can not meet higher requirements of whole vehicle carrying capacity or use environments are more severe. The utility model provides a rim structure of a light all-terrain motorcycle, which is used for improving the wheel flange outline, the wheel disk structure, the size and shape of a lightening hole, and the like. The rim structure has the characteristics that two sections of arcs at a wheel flange are not concentric, a rim is a flat-bottomed deep groove, a connecting section of a wheel disk and the rim is a straight line, a reinforcing rib groove is protruded frontward outside a center hole of the wheel disk and the like, so that the bearing capacity of the rim of the motorcycle is greatly improved under the same material thickness.
Description
Technical field
The utility model relates to a kind of light all-terrain motorcycle, specially refers to a kind of rim structure of light all-terrain motorcycle.
Background technology
Light all-terrain motorcycle is mainly used in the non-pavement usages of mating formation such as mountain region, jungle, marsh, desert, Gobi desert.Light all-terrain motorcycle is because the particularity of environment for use is more and more higher to the requirement of strength of wheel rim, but under the pressure of the demand of economy dynamic property, the weight of wheel rim can not unconfinedly increase again.At present widespread use be the rim structure of U.S.'s tyre rim association criterion (being called for short TRA) defined, when whole bearing capability being had relatively high expectations or environment for use when comparatively abominable, this kind rim structure can't meet the demands, unless increase the thickness of the whole sheet material of wheel rim, perhaps at the bracing ring of wheel rim both sides welding with the sheet material scroll.But, the thickness that increases the whole sheet material of wheel rim is difficult for realizing, also can increase the weight of car load on technique; The employing bracing ring then can be owing to the shape of bracing ring must be accomplished strict conformance with the shape of reinforcing section in the one fixed width scope, and the scroll of heavy-gauge sheeting technique be difficult for to realize etc. having because of, make the technique complicated, almost be equal to wheel rim is made two-layer the welding.
Summary of the invention
Be can not satisfying of solving that prior art light all-terrain motorcycle rim structure the exists problems such as whole bearing capability is had relatively high expectations or environment for use is comparatively abominable, the utility model proposes a kind of rim structure of light all-terrain motorcycle.The rim structure of the utility model light all-terrain motorcycle comprises:

⑸ wheel rim sheet metal thickness scope is 2.5～4.5mm;
⑹ disc and wheel rim linkage section are straight line, one section radius R of the terminal connection of straight line
3Scope is the circular arc of 18～30 mm, and the end of circular arc and one section degree of dip β scope are that 65～85 ° oblique line is tangent, form 7 fonts;
At the disc centre hole laterally, thickness H of lordosis
3Scope is the reinforced rib groove of 3～6mm;
⑻ the diameter phi of disc
2Scope is 134～198mm;
⑼ ladder type lightening hole A3～6 is opened and along circumferentially uniform in disc front near bolt hole, along disc outward flange open semicircle arc lightening grooves B3～6 and circumferentially uniform;
⑽ web thickness scope is 4～8mm.
The useful technique effect of the rim structure of the utility model light all-terrain motorcycle is by the outline line of wheel rim and the structure of disc are carried out innovative design, so that under same material thickness, the load-carrying capacity of wheel rim is largely increased.
Description of drawings
Accompanying drawing 1 is the cross-sectional schematic at the rim structure wheel rim place of the utility model light all-terrain motorcycle;
Accompanying drawing 2 is partial schematic diagrams of the rim structure disc of the utility model light all-terrain motorcycle;
Accompanying drawing 3 is disc front elevational schematic of the rim structure of the utility model light all-terrain motorcycle;
Accompanying drawing 4 is disc cross-sectional schematic of the rim structure of the utility model light all-terrain motorcycle.
Be further described below in conjunction with the rim structure of the drawings and specific embodiments to the utility model light all-terrain motorcycle.
The specific embodiment
Accompanying drawing 1 is the cross-sectional schematic at the rim structure wheel rim place of the utility model light all-terrain motorcycle, accompanying drawing 2 is partial schematic diagrams of the rim structure disc of the utility model light all-terrain motorcycle, as seen from the figure, the rim structure of the utility model light all-terrain motorcycle mainly is to improve for wheel rim outline line and web pattern, wherein:
Improvement to the wheel rim outline line mainly comprises:
⑴ wheel rim place is two sections circular arcs and decentraction, the radius R of one section circular arc
1Scope is 9.5～11.5mm, the radius R of another section circular arc
2Scope is 6～8mm.Then supporting effect is relatively poor if adopt one section circular arc or two sections concentric circular arcs.In addition, the rim structure of the utility model light all-terrain motorcycle adopt being designed with of two ends circular arc be beneficial to diameter be the bead coil of 10～12mm to the reinforcement of wheel rim place, bead coil can carry out good applying with wheel rim, stiffening effect is more obvious.
⑵ wheel rim is flat deep trouth, groove depth H
1Scope is 20～30mm, groove width L
1Scope is 60～100mm, and the outline line inclined angle alpha scope on groove both sides is 4～6 °.Such design guarantees that load-carrying capacity is the strongest in this scope, and is best with the tire fiting effect.
⑶ place, protruding peak is apart from wheel rim inner distance L
2Scope is 20～30mm, wheel rim width L
3And height H
2Scope is respectively 16～18mm.Thus, strengthened the area of contact of bead seat and wheel rim, so that the wheel rim contact stress is reduced effectively.
The diameter phi of the wheel rim of the rim structure of the utility model light all-terrain motorcycle
1Scope is 305～381mm; Rim width L
4Scope is 203～267mm; Wheel rim sheet metal thickness scope is 2.5～4.5mm;
Improvement to web pattern mainly comprises:
⑴ disc and wheel rim linkage section are straight line, one section radius R of the terminal connection of straight line
3Scope is the circular arc of 18～30 mm, and the end of circular arc and one section degree of dip β scope are that 65～85 ° oblique line is tangent, form 7 fonts.Such design is more much larger than the load-carrying capacity of square edge transition.
At the disc centre hole laterally, thickness H of lordosis
3Scope is the reinforced rib groove of 3～6mm, so that the structure of disc is better.
The diameter phi of the disc of the rim structure of the utility model light all-terrain motorcycle
2Scope is 134～198mm, and the web thickness scope is 4～8mm.
Accompanying drawing 3 is disc front elevational schematic of the rim structure of the utility model light all-terrain motorcycle, and accompanying drawing 4 is disc cross-sectional schematic of the rim structure of the utility model light all-terrain motorcycle, and among the figure, A is the ladder type lightening hole, and B is lightening grooves.As seen from the figure, under the prerequisite that guarantees load-carrying capacity, the rim structure of the utility model light all-terrain motorcycle alleviates own wt as much as possible, in the disc front near bolt hole, open ladder type lightening hole A3～6 and along circumferentially uniform, along disc outward flange open semicircle arc lightening grooves B3～6 and circumferentially uniform, when increasing load-carrying capacity, weight is controlled effectively, so that disc is accomplished is lighter
By above-mentioned improvement, the load-carrying capacity of the rim structure of the utility model light all-terrain motorcycle increases substantially, and tire force obtains effective communication and reasonable layout, and not obvious increase material thickness and rim weight.Obviously, the useful technique effect of the rim structure of the utility model light all-terrain motorcycle is by the outline line of wheel rim and the structure of disc are carried out innovative design, so that under same material thickness, the load-carrying capacity of wheel rim is largely increased.
