The invention provides a speed change device of an electric vehicle, which comprises an input shaft connected to a power motor, an output shaft linked with the input shaft, a clutch mechanism arranged on the output shaft, a speed change drum connected to the clutch mechanism, and a sensor for detecting the rotation angle of the speed change drum, and the gear shifting motor is connected to the speed change drum and is used for controlling the rotation angle of the speed change drum. The input shaft comprises a shaft body, a first gear and a second gear, wherein the shaft body is sleeved with the first gear and the second gear. The output shaft comprises a shaft rod, a first-gear gear and a second-gear gear, wherein the first-gear gear and the second-gear gear are meshed with the first gear and the second gear respectively. The clutch mechanism is arranged between the first-gear gear and the second-gear gear and comprises a sliding block capable of moving between a first-gear position and a second-gear position and a shifting fork driving the sliding block to move.

    本发明提供一种电动车的变速装置,该电动车的变速装置包含一连接于一动力马达的输入轴、一连动该输入轴的输出轴、一设置于该输出轴的离合机构、一连接于该离合机构的变速鼓、一用以侦测该变速鼓的转动角度的感知器,及一连结于该变速鼓并用以控制该变速鼓的转动角度的换档马达。该输入轴包括一轴体、套设于该轴体的一第一齿轮及一第二齿轮。该输出轴包括一轴杆、分别与该第一齿轮及该第二齿轮啮合的一个一档齿轮及一个二档齿轮。该离合机构设置于该一档齿轮与该二档齿轮间,并包括一能在一档位置与二档位置间移动的滑块,及一带动该滑块移动的拨叉。
