The invention relates to the technical field of automobiles, in particular to a decoupling device of an electric drive system, a using method of the decoupling device and a vehicle, a first bearing is mounted at a shaft neck of a gear, at least one one-way bearing is mounted between an input shaft and the gear, when the number of the one-way bearings is two, all the one-way bearings are arranged in parallel, and when the number of the one-way bearings is two, all the one-way bearings are arranged in parallel; an outer ring of the one-way bearing is matched with an inner hole of the gear, and an inner ring is in close contact with a shaft neck of the input shaft; the bearing cover is rotationally connected with the input shaft through a second bearing, and the bearing cover is fixedly connected with the gear through a bolt; a third bearing is arranged on the outer side of the bearing cover; thrust structures are arranged on the two sides of a shaft neck of the input shaft respectively, and the two thrust structures jointly play a role in axial positioning. When the main motor works independently, the auxiliary motor can be decoupled, the auxiliary motor and a transmission device of the auxiliary motor cannot be reversely dragged to participate in transmission, dragging loss and energy loss are reduced, and the transmission efficiency of the whole transmission system is improved.

    本发明涉及汽车技术领域,具体而言,涉及一种电驱动系统的解耦装置及其使用方法、车辆,齿轮的轴颈处安装有第一轴承,输入轴与齿轮之间安装至少一个单向轴承,当单向轴承的数量为两个时,所有的单向轴承并列布置,且单向轴承的外圈与齿轮的内孔相配合、内圈与输入轴的轴颈紧密接触;轴承盖通过第二轴承与输入轴转动连接,且轴承盖通过螺栓与齿轮固定连接;轴承盖的外侧装有第三轴承;输入轴的轴颈两侧分别装有止推结构,两个止推结构共同起轴向定位作用;其能够在主电机单独工作时,实现副电机解耦,不会反拖副电机及其传动装置参与传动,降低拖曳损失和能量损耗,提高整个传动系统的传动效率。
