摘要： A bead wire for a bead core of a tire, having at least one portion of its annular extent formed from a material having characteristics of superelasticity, resulting in increasing deformations of the bead core when a constant stretching load is applied at constant temperature. As the load ceases, the bead core recovers from the deformation. The characteristics of the bead core allow mounting a tire incorporating the bead core to a rim at ambient temperature, with intelligent adjustment of the bead core to the dimensions of the seat of the rim. The bead core increases the magnitude of an inward contraction stress as its temperature increases, so that it increases the gripping pressure exerted by the tire beads on the rim when the tire runs in the deflated state.

摘要： An inflation and deflation device for an inner tube and an inner tube provided with this device are described. The inner tube is elastically expandable for the introduction of fluid into its internal volume and can be housed in the space between tire and rim, which can be isolated from the external environment at atmospheric pressure. The device does not have elements for connecting the internal volume of the inner tube and the environment outside the wheel.
摘要翻译：描述了一种用于内管和设置有该装置的内管的充气和放气装置。内管是可弹性膨胀的，用于将流体引入其内部容积并且可以容纳在轮胎和轮辋之间的空间中，其可以在大气压力下与外部环境隔离。该装置没有用于连接内管的内部容积和车轮外部环境的元件。

摘要： A tire (20) comprises a bead core (22) of ferromagnetic material, for example steel wire, around which one or more windings (30a, 30b, . . . , 30n) of conducting wire are wound to form the secondary of an electricity generator of the induction type. The assembly of windings and bead core (22), together with the circuits using the electricity thus generated, is produced as a single unit to be incorporated, together with the bead filler (26), in a bead (28) of the tire, and of one or more magnets fixed with respect to the hub of the wheel or integral with the chassis of a vehicle comprising a wheel (18) fitted with the tire (20), which induce current in the windings. If the magnets are electromagnets (32) supplied with alternating current, the electricity generator operates both when the wheel (18) is rotating and when the wheel is stationary. On the other hand, if the magnets are permanent magnets (66) or electromagnets supplied with direct current, the electricity generator operates only if the wheel (18) is rotating.
摘要翻译：轮胎（20）包括铁磁材料（例如钢丝）的胎圈芯（22），围绕该胎圈芯缠绕一根或多根导线的绕组（30a，30b，...，30n）以形成电的次级感应式发电机。绕组和胎圈芯（22）的组合以及使用如此产生的电的电路与作为轮胎填料（26）一起并入轮胎的胎圈（28）中的单个单元被制造，以及相对于轮毂固定的一个或多个磁体或与车辆的底盘一体的车辆，其包括装配有轮胎（20）的轮（18），其在绕组中感应电流。如果磁体是提供有交流电的电磁体（32），则发电机在车轮（18）旋转时和车轮静止时都动作。另一方面，如果磁体是永磁体（66）或直流供电的电磁体，则发电机仅在车轮（18）旋转时才起作用。
