Embodiment 1
[0018] As shown in Figure 1, a tubeless tire is composed of a tread 1, a sidewall 2, an airtight layer 3b, a bead 4, and a rim 5. Both the tire heel arc radius 7 and the inclination angle 8 of the joint surface are designed with interference fit dimensions. Among them, the joint diameter 6 bead 4 is 150.4mm, and the rim 5 is 152.4mm; the tire heel arc radius 7 is 6.5mm for the bead 4, and the rim 5 is 6.0mm; 5 is 5°.
Embodiment 2
[0020] Referring to Figure 2, a tire with an inner tube is composed of a tread 1, a sidewall 2, an inner tube 3a, a bead 4, and a rim 5, and the fit diameter is 6, the heel arc radius is 7, and the fit surface inclination angle is 8. The interference size fit design With embodiment 1.

The invention discloses a method for preventing displacement of aerotire, which adopts interference fit dimension design for the rim diameter at the part where a tyre bead is matched with a wheel felloe, the radian radius of bead heel and the angle of inclination of rim surface. The method has the advantage that the tyre bead is firmly matched with a wheel felloe by adopting the interference fit design, so that the problem generally existing in the displacement of the aerotire at preseat is solved.
Description
technical field [0001] The invention relates to aircraft tires, in particular to a method for preventing aircraft tires from translocating. Background technique [0002] At present, the tires assembled by aircraft are basically divided into two types of tires with inner tubes and tubeless tires. Due to the positioning of the valve position of the inner tube tire, once the tire is in use, it is very easy to block the valve valve and cause the tire to leak; while the air tightness of the tubeless tire depends entirely on the innermost layer of the carcass 2mm thick The butyl rubber layer is used to maintain the tire. If the tire is not tightly fitted with the rim, or the relative rotation of the tire with the rim occurs during use, it is easy to cause the tire to lose pressure or even leak air. [0003] Therefore, no matter whether there is an inner tube or a tubeless tire, it is not allowed to be indexed in use. If there is an air leak in the position during use, the mild c...
