The invention discloses an electric automobile transmission structure with high safety performance. The electric automobile transmission structure comprises a permanent magnet motor, a rotating shaft,an automatic gearbox and walking wheels. The rotating shaft is mounted at the output end of the permanent magnet motor; the rotating shaft is connected with an input shaft of the automatic gearbox through a speed limiting shoe block mechanism for limiting the rotating speed of the rotating shaft; the walking wheels are driven by the automatic gearbox to rotate. The rotating shaft is also providedwith an electromagnetic resistance brake mechanism. The electric automobile transmission structure has the following beneficial effects: the speed limiting shoe block mechanism can limit the rotatingspeed of the rotating shaft when the speed is high, so that the safety of an automobile is improved; the electromagnetic coil can generate a magnetic force to attract a magnetic attraction mechanism,the rotating shaft can be decelerated, the auxiliary braking effect is achieved, and the braking performance of the electric automobile is improved; and the safety performance of the electric automobile can be greatly improved through the transmission mechanism.

    本发明公开了一种高安全性能的电动汽车传动结构,包括永磁电机、转轴、自动变速箱和行走轮,所述永磁电机的输出端上安装有转轴,转轴通过用于限制转轴转速的限速蹄块机构与自动变速箱的输入轴连接,行走轮由自动变速箱带动转动,转轴上还安装有电磁阻力刹车机构,本发明的有益效果是:限速蹄块机构能在速度较快时对转轴的转速进行限制,提高汽车的安全性,并且,电磁线圈能产生磁力,吸引磁吸机构,可以对转轴进行减速,起到辅助刹车的效果,提升电动汽车的刹车性能,这种传动机构可以大大提升电动汽车的安全性能。
