The invention provides a two-gear transmission for a pure electric vehicle and the pure electric vehicle. An input shaft is connected with a driving motor of the pure electric vehicle; the transmission mechanism is assembled on the input shaft; the first brake is fixedly connected to the inner wall of the transmission shell and further connected with the transmission mechanism. The second brake is fixedly connected to the inner wall of the transmission shell and further connected with the transmission mechanism. The main reduction gear is in transmission connection with the transmission mechanism; the differential assembly is in transmission connection with the main reduction gear; the driving motor transmits power through the input shaft to drive the transmission mechanism to operate, the first brake and the second brake enable the two-gear transmission to operate at different gears by changing the states of the first brake and the second brake, the main reduction gear further transmits the power transmitted by the transmission mechanism to the differential assembly, and the power is output through the differential assembly. By increasing a small amount of cost and weight, the performance of the pure electric vehicle is greatly improved, and the dynamic property and economical efficiency of the vehicle are both considered.
本申请提供一种纯电动汽车用两挡变速器及纯电动汽车,输入轴与纯电动汽车的驱动电机连接;传动机构装配在输入轴上;第一制动器固定连接在变速器壳体的内壁上,还与传动机构连接;第二制动器固定连接在变速器壳体的内壁上,还与传动机构连接;主减齿轮与传动机构传动连接;差速器总成与主减齿轮传动连接;驱动电机将动力通过输入轴传递,带动传动机构运行,第一制动器和第二制动器通过改变其自身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。通过增加少量的成本和重量,较大幅度地提升纯电动汽车的性能,兼顾车辆的动力性和经济性。
