Embodiment Construction

[0035] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0036] In order to achieve the purpose of the present invention, figure 1 A cross-sectional view of an embodiment of the present invention is shown. A hollow tire, comprising a crown 7, a carcass 1, and a fetal toe 4; a cavity 2 runs through the carcass 1, and the cavity 2 accounts for 20% to 50% of the total cross-sectional area of ​​the carcass 1 cross section.

[0037] The beneficial effects of adopting the above technical solution are: the present invention does not need to be inflated, requires less maintenance, and has the anti-stamp function. The material of the carcass can adopt the same grade of rubber as the outer tire of the ordinary tire in the prior art, which can have the same wear resistance as the existing outer tire, and the thickness of the carcass is thick, which is equivalent to having a thicker wear-resistant layer. It has a longer ser...

Abstract

The invention discloses a hollow tire. The hollow tire comprises a tire crown, a tire body and a tire toe, wherein a cavity is formed in the tire body in a penetration manner; the cavity in a cross section of the tire body is 20%-50% of total area of the cross section; the cross section of the cavity is oval or is a closed graph formed by surrounding of a major arc, an inferior arc and two tangent lines between the major arc and the inferior arc; and a limiting groove matched with a rim section is formed between the tire toe and the tire body, a circumferential groove is formed in the tire toe, a vent hole is connected between the circumferential groove and the cavity, rounded corners are arranged on the tire toe, and the rounded corner, close to the limiting groove, on the tire toe is smaller than the rounded corner far from the limiting groove. By utilizing the hollow tire, the maintenance can be reduced; and the hollow tire has an anti-pricking function, the use material of the tire body is saved, and the hollow tire is convenient to be assembled with the rim section.

Description

technical field [0001] The invention relates to tires, in particular to a hollow tire. Background technique [0002] There are three types of tires that are different from pneumatic tires in the prior art. One is composed of a general outer tire and a PU foam inner tube. This kind of tire can maintain normal tire grip and wear resistance. The disadvantage is that after the wheel set is baked, the bearing grease will melt or be lost, which will affect the smoothness of the wheel set. The contour size of the PU foam inner tube has high size requirements, depending on the size of the tire and the rim. The other is a pure foam tire, which has a solid carcass, and the connected tread pattern is made at one time. But this kind of tire section has many small air holes, and the tread also has small air holes at the same time, so it is not wear-resistant. Another kind is the PU honeycomb tire, the same wear resistance is not as good as the existing pneumatic tire, and the cost is ...
