The invention discloses a power clutch device of an electric automobile, and belongs to the technical field of mechanical transmission. The power clutch device comprises a box body, a box cover, an input shaft sleeve, an output shaft and a clutch sleeve sleeving on the output shaft, the input shaft sleeve and the output shaft are coaxially butted and can rotate relatively, and the output shaft and the input shaft sleeve can be combined or separated by the axial movement of the clutch sleeve, and thus the power connection or disconnection between the motor shaft and the gearbox is realized; the clutch sleeve is connected with a thrust structure used for controlling axial movement of the clutch sleeve, and a spring reset structure is arranged on the other side of the clutch sleeve. The device also comprises two sets of limiting devices with indicating lamps. When the clutch sleeve moves to two limiting positions, the corresponding limiting devices are triggered to act respectively so that the corresponding indicating lamps are lightened. The clutch device is used for the electric automobile with a driving and charging integrated system, power connection between the motor shaft and the automobile gearbox can be cut off in the charging process, and electric energy waste and automobile vibration caused by the fact that the motor shaft rotates to drag automobile transmission parts in the charging process are avoided.

    本发明公开了一种电动汽车动力离合装置,属于机械传动技术领域,其包括箱体、箱盖、输入轴套、输出轴和套设在输出轴上的离合套,输入轴套与输出轴同轴对接且两者可相对转动,离合套的轴向移动可致使输出轴与输入轴套结合或脱离,从而实现电机轴到变速箱的动力连接或断开;所述离合套上连接有用于控制其轴向移动的推力结构,离合套另一侧设有弹簧复位结构;还包括两组带指示灯的限位装置,当离合套移动到两个极限位置时分别触动对应的限位装置动作以致使对应的指示灯亮。该离合装置用于具有驱动充电集成系统的电动汽车,能够在充电时切断电机轴到汽车变速箱的动力连接,避免充电时因电机轴转动拖转车辆传动部件而引起电能浪费和车辆震动。
