The invention discloses an eddy current brake magnet. The eddy current brake magnet is used for a brake system of a rail transit vehicle running on a steel rail or a rail. The eddy current brake magnet comprises a magnet yoke which is arranged at the bottom of the rail transit vehicle through supporting arms on the two sides; a plurality of magnetic poles disposed below the yoke; under the condition that the rail transit vehicle is braked, the vertical suction force generated by the magnetic pole close to the midpoint of the magnet yoke is smaller than the vertical suction force generated by the magnetic pole far away from the midpoint of the magnet yoke; the middle point of the magnet yoke is located at the distance middle point of the supporting arms on the two sides. According to the scheme, the magnetic poles are designed into different suction force levels, distribution of the suction force of the magnetic poles on the magnet yoke is optimized, and high eddy current braking force is obtained on the premise that the installation space and the deflection of the magnet yoke are limited.

    本发明公开了一种涡流制动磁铁,所述涡流制动磁铁用于在钢轨或铁轨上行驶的轨道交通车辆的制动系统;所述涡流制动磁铁包括:磁轭,通过两侧的支撑臂设置在所述轨道交通车辆的底部;设置在磁轭下方的多个磁极;在所述轨道交通车辆制动的情况下,靠近磁轭中点的磁极所产生的垂向吸力小于远离磁轭中点的磁极所产生的垂向吸力;其中,磁轭中点位于两侧支撑臂的距离中点。本方案通过将磁极设计成不同吸力水平,优化磁极吸力在磁轭上的分布,实现在安装空间和磁轭挠度限定的前提下获得较高的涡流制动力。
