摘要： A tire includes a toroidal carcass and a tread band. The toroidal carcass includes a central crown and two sidewalls terminating in a pair of annular beads. Each annular bead includes a metallic bead core for anchoring to corresponding bead seats of a wheel rim. The metallic bead cores include at least one annular portion made of a material having characteristics of superelasticity and shape memory. The material having characteristics of superelasticity and shape memory is deformable at ambient temperature in response to a constant force and recovers to an original shape upon removal of the constant force to facilitate mounting the tire on the wheel rim. The wheel rim includes a central cylindrical channel from which branches off, axially and outwardly, from opposite sides, diverging surfaces each terminating in a peripheral flange. The diverging surfaces form the bead seats for respective annular beads of the tire.

摘要： A method of mounting a tire on a rim includes selecting a tire comprising bead cores, stretching the bead cores, sliding the bead cores over a balcony portion of the rim, allowing the bead cores to elastically return to lengths corresponding to diameters of respective seats of the rim, and inflating the tire. The bead cores include one or more portions of material with characteristics of superelasticity and shape memory. Stretching the bead cores may include applying constant load to the bead cores at ambient temperature and/or causing the bead cores to undergo structural change at ambient temperature. The structural change may include complete or partial change from austenitic structure to martensitic structure. The one or more portions of material are deformable at ambient temperature in response to a constant force and recover to original shape upon removal of the constant force.
摘要翻译：将轮胎安装在轮辋上的方法包括选择包括胎圈芯的轮胎，拉伸胎圈芯，使胎圈芯在轮辋的阳台部分上滑动，允许胎圈芯弹性恢复到对应于相应座位直径的长度轮辋，并使轮胎充气。珠芯包括具有超弹性和形状记忆特性的材料的一个或多个部分。拉伸胎圈芯可以包括在环境温度下对胎圈芯施加恒定负载和/或使胎圈芯在环境温度下经历结构变化。结构变化可能包括从奥氏体结构到马氏体结构的完全或部分变化。材料的一个或多个部分响应于恒定的力在环境温度下变形，并且在去除恒定力时恢复到原始形状。

摘要： A bead core for locking a tire to a seat of a wheel rim includes a plurality of annular reinforcement elements having an inner transverse dimension smaller than a maximum diameter of the wheel rim, and being sufficiently deformable at ambient temperature to facilitate mounting the tire onto the wheel rim. The plurality of annular reinforcement elements includes at least one tightening element made of a shape-memory alloy responsive to temperature increases by increasing a tightening force on the wheel rim at a predetermined temperature. A tire including the bead core and a method for securing a tire to a rim using the bead core are also disclosed.

摘要： A tire includes a carcass, a tread band, at least a reinforcing belt between the tread band and the carcass, a pair of bead cores disposed one at each end of the carcass with ends of the carcass wrapped around the pair of bead cores to form a pair of beads, and at least one clamp disposed around each bead core, wherein the at least one clamp is made of a shape-memory material. A bead core including at least one clamp made of a shape-memory material, a method for manufacturing a tire including at least one clamp made of a strip of shape-memory material, and a method for manufacturing a bead core including at least one clamp made of a strip of shape-memory material are also disclosed.
