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.
