Title:
HOLLOW TIRE
Document Type and Number:
WIPO Patent Application WO/2018/223737
Kind Code:
A1
Abstract:
A hollow tire, comprising a tire crown (7), a tire body (1), and a bead toe (4). A cavity (2) runs through the tire body (1). In a cross-section of the tire body, the area of the cross-section of the cavity accounts for 20% to 50% of the total area of the cross-section of the tire body. The cross-section of the cavity is elliptical, or is a closed shape defined by a major arc, a minor arc and two common tangent lines between the major arc and the minor arc. A position-limiting groove (3) matching the wheel rim is disposed between the bead toe and the tire body. The bead toe is provided with a circumferential groove (5). An air hole is connected between the circumferential groove and the cavity. The tire toe has rounded corners, and the rounded corner near the position-limiting slot is smaller than the rounded corner away from the position-limiting slot. The hollow tire reduces the need for maintenance, has an anti-puncture function, reduces materials required for making the tire body, and can be fitted to a wheel rim with ease.
