The invention provides a locomotive windscreen wiper. The locomotive windscreen wiper comprises a wiping arm assembly, a support mechanism and a wiping piece. A shell capable of elastically deforming is arranged in the support mechanism, and the shell is filled with magnetorheological fluid; the scraping and brushing piece is clamped between the two shells in a limiting manner, and the scraping and brushing piece is provided with an elastic assembly; an electromagnetic generator is assembled on the wiping arm assembly; when the electromagnetic generator generates a magnetic field effect, the two shells face each other and abut against the elastic assembly to be in a first state. When the electromagnetic generator does not generate the magnetic field effect, the two shells are far away from each other, so that the elastic assembly is elastically released to be in a second state. According to the description, the characteristics of the magnetorheological fluid are changed through the electromagnetic generator, so that the shell is relatively deformed, the state of the scraping and brushing piece is changed, and the fitting degree of the scraping and brushing piece and the glass is increased; and meanwhile, it is guaranteed that during primary use, dust or sand in the gap is avoided through relative tightening, the dust or sand is pushed and removed in parallel at the attached portion of the scraping and brushing piece and the glass, and the cleanliness of the locomotive glass can be achieved at the first time.
本申请提供了一种机车雨刮器,包括刮臂组件、支架机构、刮刷件;支架机构的内部设置有可弹性形变的壳体,壳体的内部充盈有磁流变液;刮刷件限位卡合在两个壳体之间,且刮刷件具有弹性组件;刮臂组件上装配有电磁发生器;电磁发生器产生磁场作用时,两个壳体相互朝向抵压弹性组件处于第一状态;电磁发生器未产生磁场作用时,两个壳体相互远离使弹性组件弹性释放处于第二状态。以上描述中可以看出,通过电磁发生器改变磁流变液的特性,使壳体相对形变,改变刮刷件的状态,增加刮刷件与玻璃的贴合度;同时保证在初次使用时,相对收紧对间隙内的尘土或沙粒进行避让,刮刷件与玻璃的贴合部位平行推除尘土或沙粒,初次便可实现机车玻璃的清洁度。
