Tire with lip edge structure
A tire with a lip edge structure comprises a tire body having an opening; two lip edges formed on two sides of the opening; two adhering portions; each lip edge having an adhering portion; a steel beam being embedded in the adhering portion for retaining the tire body; the adhering portion being an enlarged cambered portion, which protrudes at an outer portion of the tire body; two slide-proof cloths; an outer side of each adhering portion being enclosed by one of the mono-nylon slide-proof cloth. The slide-proof cloths are made of mono nylon with a rubber layer; the rubber layer has a thickness between 0.3 mm to 2.0 mm. The slide-proof cloth is interleaved by mono-nylon of 10˜50*10˜50 EPI and is interleaved by mono-nylon with each yarn being ranged from 210 Diner to 840 Diner. The lip edges are made of Kevlar Bead.
The present invention relates to tires, and particular to a tire with a lip edge structure; wherein the adhering portions of the lip edges have outward cambered shapes so as to tightly buckle the wheel rims. A slide-proof cloth is placed upon each adhering portion so as to provide a friction force to the interface between the adhering portions and the wheel rim.
BACKGROUND OF THE INVENTIONIn the prior art, tires can be classified as tube type (TT) and tubeless type (TL). The prior art tires are fixed to wheel rims by lip edges of the tires. In the design of lip edges, it is necessary to prevent the lip edges from sliding and releasing and the connection of the lip edges and the wheel rims must be air-tight so as to provide a safety driving to users.
With reference to
Referring to
To improve the defect in the prior art, sealant is filled in the gap and the contact surfaces of the adhering portions and wheel rims. Or the wheel rim is shaped to match the shape of the lip edges. However, this will increase the cost. Especially, the tubeless type tire has a cost of 10 higher than that of the tube type tire.
However, from
In one development, the adhering portion is textured so as to increase the friction force between the adhering portions and the wheel rims to have a preferred slide-proof effect, but this will cause that the air is vented from the gaps in the texture regions.
SUMMARY OF THE INVENTIONAccordingly, the primary object of the present invention is to provide a tire with a lip edge structure, wherein the adhering portions have an outward cambered shapes for tightly buckling the wheel rims.
Another object of the present invention is to provide a tire with a lip edge structure, wherein a slide-proof cloth is placed upon the adhering portion so as to provide a friction force to the interface between the adhering portions and the wheel rim.
A further object of the present invention is to provide a tire with a lip edge structure, wherein sealant is filled between the contact surfaces of the adhering portions and the wheel rim so that no air can vents from the tire.
To improve the defect in the prior art, the present invention provides a tire with a lip edge structure which comprises a tire body having an opening; two lip edges formed on two sides of the opening; two adhering portion; each lip edge having a respectively adhering portion; a steel beam being embedded in the adhering portion for retaining the tire body; the adhering portion being an enlarged cambered portion, which protrudes at an outer portion of the tire body; two slide-proof cloths; an outer side of each adhering portion being enclosed by one of the mono-nylon slide-proof cloths. The slide-proof cloths are made of mono nylon with a rubber layer; and the rubber layer has a thickness between 0.3 mm to 0.2 mm. The slide-proof cloth is interleaved by mono-nylon of 10˜50*10˜50 EPI and is interleaved by mono-nylon with each yarn being ranged from 210 Diner to 840 Diner. The lip edges are made of Kevlar Bead.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to
A tire body 10 has an opening.
Two lip edges 12 are formed on two sides of the opening. The lip edges 12 are mainly made of Kevlar bead.
Each lip edge 12 has an adhering portion 14. A steel beam 16 is embedded in the adhering portion 14 for retaining the tire body 10. The adhering portion 14 is an enlarged cambered portion, which protrudes at an outer portion of the tire body 10.
An outer side of each adhering portion 14 is enclosed by a mono-nylon slide-proof cloth 20 so as to cause the gap between the tire body 10 and a wheel rim 30 is minimized to have a preferred air-tightness.
Referring to
With reference to
Moreover, by the cambered adhering portion 14 and the slide-proof cloth 20 of the present invention, the present invention is suitable to various kinds of wheel rims 30 currently used. However, the prior art design is dedicated to one specific kind of wheel rim 30. Thereby, the present invention is superior than the prior art.
With reference to
A surface of the slide-proof cloth 20 and the contact portion 34 of wheel rim 30 are coated with sealant so that the sealant can fill the gaps between the slide-proof cloth 20 and the wheel rim 30. Thereby, a preferred air-tightness is achieved.
With reference to
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
