Rotary joint with energy harvesting structure

A rotary joint for a tire inflation system of a heavy vehicle includes an energy harvesting structure for generating electrical power to power electronic components of the heavy vehicle. The energy harvesting structure is integrated with and protected by the rotary joint. The energy harvesting structure includes components of respective static and rotatable components attached to the rotary joint that generate electrical power for powering the electronic components during rotational movement of the rotatable component relative to the static component during operation of the heavy vehicle. Components of the energy harvesting structure may be completely excluded from or separated from and hermetically isolated from the flow path of pressurized air through the rotary joint. 一种用于重型车辆的轮胎充气系统的旋转接头，所述旋转接头包括用于产生电力以为重型车辆的电子部件供电的能量获取结构。能量获取结构与旋转接头集成在一起并被其保护。能量获取结构包括附接到旋转接头的相应静态部件和可旋转部件的部件，所述部件在重型车辆的操作期间可旋转部件相对于静态部件的旋转运动期间产生电力以用于为电子部件供电。能量获取结构的部件可以被从通过旋转接头的加压空气的流动路径完全排除或分离并与其密封隔离开。
