The invention provides a two-gear transmission and a pure electric vehicle, the pure electric vehicle comprises a driving motor, the two-gear transmission comprises an input shaft, a first clutch, a second clutch, a transmission mechanism, a main reduction gear and a differential mechanism assembly, and the input shaft is connected with the driving motor; the first clutch and the second clutch are respectively connected with the input shaft; the transmission mechanism is assembled on the first clutch and the second clutch to form different power transmission paths; the main reduction gear is in transmission connection with the transmission mechanism; the differential mechanism assembly is connected with the main reduction gear; the driving motor transmits power through the input shaft to drive the first clutch and the second clutch to operate, the first clutch and the second clutch enable the two-gear transmission to operate at different gears by changing the combination state of the first clutch and the transmission mechanism and the combination state of the second clutch and the transmission mechanism, and the main reduction gear further transmits the power transmitted by the transmission mechanism to the differential mechanism assembly. And the differential assembly is used for outputting, so that the power performance of the whole vehicle is greatly improved under the condition that a small amount of cost and weight are increased.

    本申请提供一种两挡变速器及纯电动汽车,纯电动汽车包括驱动电机,两挡变速器包括输入轴、第一离合器、第二离合器、传动机构、主减齿轮、差速器总成,输入轴与驱动电机连接;第一离合器和第二离合器分别与输入轴连接;传动机构装配在第一离合器和第二离合器上,形成不同的动力传输路径;主减齿轮与传动机构传动连接;差速器总成与主减齿轮连接;驱动电机将动力通过输入轴传递,带动第一离合器和第二离合器运行,第一离合器和第二离合器通过改变自身与传动机构的结合状态使两挡变速器运行在不同的挡位,主减齿轮将传动机构传递的动力进一步传递给差速器总成,通过差速器总成进行输出,以在增加少量成本和重量的条件下较大地改善整车动力性能。
