Title: (EN) Tyre apparatus
(ZH) 轮胎装置
Abstract: front page image
(EN) A tyre apparatus is provided, the apparatus including a tyre body (14) for attachment to a wheel rim (12) to define a first inflatable volume (16). An inner chamber (18) defines a second inflatable volume (20) which is located within the first inflatable volume (16) of the tyre body (14). A first fluid communication path is provided between the first and second inflatable volumes (16, 20) and a second fluid communication path is provided between the first inflatable volume (16) and the atmosphere. A first valve (22) opens and closes the first fluid communication path, and a second valve (24) opens and closes the second fluid communication path. The tensile strength and pressure-containing capacity of the material structure of the second inflatable volume (20) is greater than that of the tyre first inflatable volume (16). A first fluid pressure within the first inflatable volume (16) of the tyre body (14) is optimisable by opening the first valve (22) to allow pressure transfer from the second inflatable volume (20) into the tyre body (14), and/or opening the second valve (24) to allow pressure to vent from the tyre body (14) to atmosphere. A vehicle wheel and active tyre pressure control system incorporating the tyre apparatus are also provided.
(ZH) 提供一种轮胎装置,装置包括附接至轮辋(12)以界定第一可充气容积(16)的轮胎主体(14)。内腔(18)界定在轮胎主体(14)的第一可充气容积(16)内的第二可充气容积(20)。第一和第二可充气容积(16、20)间设第一流体通路,且第一可充气容积(16)和大气间设第二流体通路。第一阀(22)打开并关闭第一流体通路,且第二阀(24)打开并关闭第二流体通路。第二可充气容积(20)的材料结构的拉伸强度和承压能力大于轮胎第一可充气容积(16)的材料结构的拉伸强度和承压能力。轮胎主体(14)的第一可充气容积(16)内的第一流体压力通过打开第一阀(22)以允许压力从第二可充气容积(20)传至轮胎主体(14)内,和/或打开第二阀(24)以允许压力从轮胎主体(14)排至大气可优化。还提供包含轮胎装置的车轮和主动轮胎压力控制系统。
