    Abstract: A tyre apparatus is provided, the apparatus including a tyre body for attachment to a wheel rim to define a first inflatable volume. An inner chamber defines a second inflatable volume which is located within the first inflatable volume of the tyre body. A first fluid communication path is provided between the first and second inflatable volumes and a second fluid communication path is provided between the first inflatable volume and the atmosphere. A first valve opens and closes the first fluid communication path, and a second valve opens and closes the second fluid communication path. The tensile strength and pressure-containing capacity of the material structure of the second inflatable volume is greater than that of the tyre first inflatable volume. A first fluid pressure within the first inflatable volume of the tyre body is optimisable by opening the first valve to allow pressure transfer from the second inflatable volume into the tyre body, and/or opening the second valve to allow pressure to vent from the tyre body to atmosphere. A vehicle wheel and active tyre pressure control system incorporating the tyre apparatus are also provided.

    Abstract translation: 提供了一种轮胎装置，该装置包括用于附接到轮缘的轮胎主体，以限定第一可充气体积。 内室限定位于轮胎主体的第一可充气体积内的第二可充气体积。 在第一和第二可膨胀体积之间提供第一流体连通路径，并且在第一可充气体积和大气之间设置第二流体连通路径。 第一阀打开和关闭第一流体连通路径，第二阀打开和关闭第二流体连通路径。 第二可膨胀体积的材料结构的拉伸强度和耐压容量大于轮胎第一可充气体积的拉伸强度和压力容纳能力。 轮胎主体的第一可膨胀体积内的第一流体压力通过打开第一阀来允许压力从第二可膨胀容积传递到轮胎主体中并且/或打开第二阀以允许压力从轮胎本体排出而是最佳的 到大气。 还提供了一种结合轮胎装置的车轮和主动轮胎压力控制系统。
