The invention provides a pure electric two speed transmission. The transmission comprises a rear gear ring, a rear planet wheel, a drive motor and a differential which are coaxially arranged, wherein a motor rotor of the drive motor is coaxially connected fixedly with a sun wheel of a planet row, a front planet wheel and the rear planet wheel of the planet row are arranged in parallel left and right and are fixedly connected to sleeve a planet wheel shaft of a planet frame in an empty manner, the front planet wheel is meshed with the sun wheel and positioned between the sun wheel and a front gear ring, the rear planet wheel is meshed with the rear gear ring, a left transmission shaft penetrates through the motor rotor of the drive motor, the sun wheel of the planet row and a central hole of the planet frame sequentially, the left end of the left transmission shaft extends out of the drive motor, the right end of the left transmission shaft extends into a differential shell and is fixedly connected with a left semi-axis gear, and a first clutch and a second clutch are connected to the front gear ring and the rear gear ring of the planet row respectively, and are externally connected onto a transmission box. The pure electric two speed transmission has relatively small overall radial size and relatively small occupied space, can be applied to an automobile with relatively large or small radial assembling space, and is better in adaptability.
