The invention discloses a railway hump electromagnetic vehicle speed reducer which is used for being installed on two stock rails distributed longitudinally. The invention also comprises iron cores, magnet exciting coils, wear-resisting plates, brake plates and a sleeper slab, the iron core is mounted on the sleeper slab; each basic rail is positioned in one iron core; the two iron cores are provided with two magnet exciting coils distributed in a surrounding mode, and wear-resisting plates are fixed to the tops of the left side and the right side of each iron core respectively. Each brake plate capable of moving in the direction perpendicular to each stock rail is laid on the top of each wear-resisting plate in the longitudinal direction; for the two brake plates above each iron core, a transverse gap between the two brake plates is used for guiding wheels needing to be braked. After the magnet exciting coil of the railway hump electromagnetic vehicle speed reducer is electrified, a closed magnetic field surrounding the iron cores, the wear-resisting plate, the brake plate, wheels of a vehicle needing to be braked and the like is generated, friction braking and eddy current braking are carried out on the wheels of the vehicle to jointly decelerate the vehicle, and the speed reduction effect on the railway vehicle is guaranteed.

    本发明公开了一种铁路驼峰电磁车辆减速器,用于安装在两根纵向分布的基本轨上;包括铁芯、励磁线圈、耐磨板、制动板和轨枕板;铁芯安装在轨枕板上;每根基本轨位于一根铁芯中;两根铁芯上具有环绕分布的两个励磁线圈,每根铁芯的左右两侧顶部,分别固定有耐磨板;每个耐磨板的顶部,沿着纵向,分别平铺放置有可沿着垂直于基本轨方向移动的一根制动板;对于每根铁芯上方的两根制动板,两根制动板之间的横向间隙,用于导入需要制动的车轮。本发明的铁路驼峰电磁车辆减速器的励磁线圈通电后,产生环绕铁芯、耐磨板、制动板与需要制动的车辆的车轮等的封闭磁场,通过对车辆的车轮进行摩擦制动和涡流制动来共同对车辆减速,保证对铁路车辆的减速效果。
