The invention relates to a gear shifting motor, a gear shifting method and an electric vehicle using the motor, the gear shifting motor comprises a center shaft, a hub shell is arranged on the center shaft in a penetrating mode, a middle drive motor and a planetary reducer are arranged in the hub shell, a clutch is further arranged in the hub shell, and the clutch comprises a friction ring, a flange plate and a transmission shaft, the friction ring is connected with the hub shell, and the flange plate is coaxially arranged on the inner side of the friction ring. The flange plate is connected with the middle drive motor, one end of the swing arm is hinged to the flange plate, the other end of the swing arm is movably arranged on the flange plate, the locking block is slidably connected to the swing arm through a pin shaft, and the roller is located on the side, away from the flange plate, of the locking block and moves reversely along with movement of the locking block. When relative displacement occurs between the roller and the locking block, the roller is pressed towards the locking block, the top spring is fixed to the inner wall of the flange plate, the end, close to the locking block, of the top spring is connected with a top column, the motion path of the locking block has the two states that the locking block extrudes towards the top column and slides away from the top column, one end of the tension spring is connected with the swing arm, and the other end of the tension spring is fixedly connected to the side wall of the flange plate of the clutch.

    本发明涉及一种变档电机及变档方法、应用该电机的电动车,包括中心轴,中心轴上穿设轮毂外壳,轮毂外壳内设有中驱电机、行星减速器,所述轮毂外壳内还设有离合器,所述离合器包括:摩擦圈,与轮毂外壳相连,法兰板,同轴设置在摩擦圈内侧,与中驱电机相连,摆臂,一端铰接于法兰板上,另一端在法兰板活动设置,锁紧块,通过销轴滑移连接在摆臂上,滚子,位于锁紧块背离法兰板的一侧,随锁紧块的运动而反向运动;滚子与锁紧块之间发生相对位移时,滚子压向锁紧块,顶簧,固定在法兰板内壁,顶簧靠近锁紧块的一端连接有顶柱,锁紧块的运动路径有:朝向顶柱挤压、背离顶柱滑移两种状态,拉簧,一端与摆臂相连,另一端固定连接离合器的法兰板侧壁上。
