    • A railway axle hub unit of the type comprising an axle box housing (1) for supporting a bearing, is provided with a sensor body (3, 9) containing sensors (4, 5) for detecting vibration in the vertical direction and the horizontal axial direction. The sensor body is mounted onto a stationary support element (2, 1, 15) rigidly secured to the bearing, preferably an annular sealing insert. The sensors perform monitoring of the operation condition of the hub unit by generating and transmitting signals indicative of the detected level of vibration to an electronic processing unit mounted on board of the railway vehicle or the train. The processing unit is capable of signalling in real time an impending failure and/or a damaged condition associated with the monitored hub unit.
    • 一种包括用于支撑轴承的轴箱壳体(1)的类型的铁路轴毂单元设置有传感器主体(3,9),其包含用于检测垂直方向上的振动的传感器(4,5)和水平轴向 方向。 传感器主体安装在刚性地固定到轴承的固定支撑元件(2,15,15)上,优选地是环形密封插入件。 传感器通过将表示检测到的振动水平的信号生成并发送到安装在铁路车辆或列车上的电子处理单元来对轮毂单元的运行状况进行监视。 处理单元能够实时地发出即将发生的故障和/或与所监视的集线器单元相关联的损坏状况。
