The invention discloses an electric automobile transmission mechanism with high brake performance. The electric automobile transmission mechanism comprises a permanent magnet motor, an electromagneticresistance brake mechanism, an oil pressure clutch, a gearbox and walking wheels. The output terminal of the permanent magnet motor is connected with a rotating shaft; the rotating shaft is connectedwith the input terminal of the gearbox through the oil pressure clutch; the electromagnetic resistance brake mechanism for assisting in braking is further mounted on the rotating shaft; an output shaft is mounted at the output terminal of the gearbox; the output shaft drives the walking wheels to rotate through a transmission shaft. The electric automobile transmission mechanism has the followingbeneficial effects: the electric automobile is started from a low gear and carries out gear shifting to the higher gear gradually; the current rotating speed of the permanent magnet motor is controlled to be the optimal effective rotating speed, the current is guaranteed to be within a small range, the battery life of the electric automobile is higher; meanwhile, the electromagnetic resistance brake mechanism installed on the rotating shaft can attract the magnetic attraction mechanism through electricity, and a good auxiliary brake function is achieved.

    本发明公开了一种高刹车性能的电动汽车传动机构,包括永磁电机、电磁阻力刹车机构、油压离合器、变速箱和行走轮,所述永磁电机的输出端与转轴连接,转轴通过油压离合器与变速箱的输入端连接,并且转轴上还安装有用于辅助刹车的电磁阻力刹车机构,变速箱的输出端安装有输出轴,输出轴通过传动轴驱动行走轮转动,本发明的有益效果是:电动汽车由低档起步,逐步往高档进行换挡,永磁电机的电流转速控制在最佳的有效转速,电流保证在较小的范围内,使得电动汽车的的电池续航能力更强,同时,转轴上安装的电磁阻力刹车机构能利用电生刺,来实现对磁吸机构的吸引,实现较好的辅助刹车功能。
