The invention relates to a monitoring structure, and relates to the technical field of railway vehicles. The monitoring structure comprises a shell device, a temperature sensing piece and an energy supply device which are coaxially arranged with a wheel shaft assembly. The shell device is arranged on the bearing end cover; the temperature sensing part is arranged on the shell device, the temperature sensing part abuts against the bearing end cover and generates a corresponding temperature sensing electric signal, the energy supply device comprises a rotating assembly, a power generation assembly and a static assembly which are arranged in the shell device, the rotating assembly is arranged on the shell device and rotates along with the shell device, and the static assembly is in a static state; wherein a part of the power generation assembly is connected with the rotating assembly, and the other part of the power generation assembly is connected with the static assembly, so that the power generation assembly generates electric energy and supplies the electric energy to the temperature sensing piece. According to the technical scheme disclosed by the invention, the problems of low accuracy and low effectiveness of a temperature measurement mode of the axle assembly and complex wiring and high installation cost caused by the need of external power supply can be solved.

    本发明涉及一种监测结构,涉及铁路车辆技术领域。本发明的监测结构包括轮轴组件同轴设置的壳体装置、温度感测件以及供能装置;壳体装置设置于轴承端盖上;温度感测件设置于壳体装置上,温度感测件与轴承端盖相抵接并产生相对应的温度感测电信号,供能装置包括设置于壳体装置内的转动组件、发电组件与静止组件,转动组件设置于壳体装置上并随壳体装置转动,静止组件处于静止状态;其中,发电组件的部分与转动组件相连,发电组件的另一部分与静止组件相连,以使发电组件产生电能并为温度感测件供能。本申请所公开的技术方案能够解决轮轴组件的测温方式精确度不高且实效性低、以及需要外接供电而导致布线复杂并且安装成本高的问题。
