The invention provides a miniature Hall multi-channel speed sensor for a railway vehicle, and belongs to the technical field of sensors. The speed sensor comprises: a first shell; a colloid assembly,which is mounted in the first shell and comprises a second shell, a limiting part and a gap part being arranged between the second shell and the first shell; an inner core structure, which is installed in the second shell, wherein the inner core structure comprises a support, a plurality of mounting stations being arranged on the support; a plurality of Hall elements respectively and correspondingly mounted on the mounting stations; two printed boards, each printed board being bonded with a connecting piece made of a porous flexible material, the two printed boards being synchronously connected to the support, and the two printed boards being electrically connected with the plurality of Hall elements; and a lining pipe, wherein the two ends of the lining pipe are connected with the first shell and the cable in a nested mode correspondingly. According to the invention, four-channel and six-channel transmission is realized, glue stress is eliminated, and phase adjustment during assemblyis avoided.

    本发明提供了一种轨道车辆用小型化霍尔多通道速度传感器,属于传感器技术领域,包括:第一壳体;胶体组件,安装于第一壳体内,其中,胶体组件包括:第二壳体,与第一壳体之间设置有限位部和间隙部;内芯结构,安装于第二壳体内,其中,该内芯结构包括:支架,且在支架上设置有若干个安装工位;多个霍尔元件,分别对应安装于每一个安装工位上;两个印制板,且在每一个印制板上粘接一个由多孔柔性材料制成的连接件,并同步连接于支架上,其中,两个印制板与多个霍尔元件电连;内衬管,两端分别与第一壳体和电缆线嵌套连接。本发明实现四通道、六通道的传输,并消除胶应力,以及避免装配时的相位调整。
