Abstract
The invention discloses a high-strength and inner tube-free rim of a motorcycle, which comprises a rim body, wherein grooves for mounting a tire and lug bosses connected with spokes are arranged on the rim body; the lug bosses are of double-layered structures; and cavities are formed in the middle of the lug bosses. As the lug bosses connected with the spokes are of the double-layered structures, the strength of the rim can be enhanced, the quality of the rim is improved, and meanwhile, an inner tube-free tire is convenient to install, so that inner tube-free tires can be widely applied to off-road motorcycles, and the quality of the motorcycles can be effectively improved.
Description
Technical field
The present invention relates to a kind of rim, particularly a kind of high-intensity inner tube free motor rim.
Background technology
Motor bike is no matter being common car with cross-country car etc. all is the same individual layer rim in the market, is that different the cars intensity and the toughness that require are different.Continuous upgrading along with the wheel product has produced split type wheel, i.e. rim, and spoke and flower-drum can separate, and this wheel combination intensity and toughness all are subjected to being extensive use of of cross-country car than monolithic wheel height.And inner tube free technology air-tightness is better, can guarantee air tightly for a long time, and the tire working temperature is lower, and long service life is simple in structure, and light weight helps running at high speed of automobile; Because tyre airtight layer is that one deck inner membrance tightly is bonded on the tire inner wall, make tire in running at high speed, be difficult for heat build-up, when puncture of tire, pressure can sharply not descend, can safety continue the segment distance that travels; Do not exist because of rubbing between the inside and outside tire and blocking the damage that causes,, therefore be highly suitable on the cross-country car and use because tubeless tires has above-mentioned advantage.
But the profile of the rim of cross-country motorcycle design at present all is a single layer structure, strength enhancing is very limited, and because the problem of the leak tightness between spoke copper cap and the circle, common individual layer locomotive circle will be done relatively difficulty of inner tube free circle, thereby has limited the application of tubeless tires on cross-country motorcycle.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides the motor rim that a kind of load is big, intensity is high and can conveniently use tubeless tires to install.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of high strength inner tube free motor rim comprises a circle body, described circle body be provided with groove that tire is installed and with spoke bonded assembly lug boss, described lug boss is a double-decker, forms cavity in the middle of the described lug boss.
Preferably, the material of described circle body is an aluminum alloy materials.
Preferably, the groove of installation tire is U-lag, V-shaped groove or dovetail groove on the described circle body.
Technique scheme has following beneficial effect: this motor rim and spoke bonded assembly lug boss are double-decker, can effectively strengthen the intensity of rim like this, improve the quality of rim, lug boss is the installation that double-decker also can make things convenient for tubeless tires simultaneously, tubeless tires can be more widely used on cross-country motorcycle, and then also can effectively improve the quality of motor bike.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the section drawing of rim in the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this high strength inner tube free motor rim comprises a circle body 1, and the material of circle body 1 is an aluminum alloy materials.Circle body 1 be provided with groove 2 that tire is installed and with spoke bonded assembly lug boss 3, the groove 2 that tire is installed on the circle body 1 can be U-lag, V-shaped groove or dovetail groove.Lug boss 3 is a double-decker, forms cavity 4 in the middle of the lug boss.
Lug boss 3 double-deck welding adopt " moment is closed technology " to solve the problem of double-deck motor rim dry joint, and circle body 1 adopts the T6 aluminum alloy materials to weld, and make the welding back become the performance of circle body to reach optimum regime.
This motor rim and spoke bonded assembly lug boss are double-decker, can effectively strengthen the intensity of rim like this, improve the quality of rim, rim detects requirement: " adding load by the diametric(al) of taking turns disappointed weld seam; rim diameter deflection 20MM; reaching load should be greater than 500KGF, and after the unloading, the wheel rim commissure is not split." testing result is: " weld seam does not split for maximum load: 1704.8KGF, 1685.9KGF." this match that is designed to MOTOCROSS and SUPERCROSS provides good selection.Lug boss is the installation that double-decker also can make things convenient for tubeless tires simultaneously, tubeless tires can be more widely used on cross-country motorcycle, and then also can effectively improve the quality of motor bike.
More than a kind of high strength inner tube free motor rim that the embodiment of the invention provided is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
Claims (3)
1. a high strength inner tube free motor rim comprises a circle body, described circle body be provided with groove that tire is installed and with spoke bonded assembly lug boss, it is characterized in that: described lug boss is a double-decker, forms cavity in the middle of the described lug boss.
2. high strength inner tube free motor rim according to claim 1, it is characterized in that: the material of described circle body is an aluminum alloy materials.
