The invention provides a driving motor anti-counter-dragging device and an electric vehicle, the driving motor anti-counter-dragging device comprises a first connecting piece, a second connecting piece and a connection switching piece, the first connecting piece is used for being connected with a power output shaft of a driving motor, the second connecting piece is used for being connected with a power input shaft of a wheel speed reducing mechanism, and the connection switching piece is used for being connected with the first connecting piece. The connecting switching piece is provided with a power transmission position meshed with the first connecting piece and the second connecting piece at the same time and an anti-dragging position at least disengaged from any one of the first connecting piece and the second connecting piece, and the connecting switching piece can be switched between the two positions. When a vehicle breaks down and needs to be towed, the connection switching piece can be switched from the power transmission position to the anti-drag position, the wheel speed reducing mechanism and the power output shaft of the driving motor are separated from transmission connection, and the situation that the motor is damaged due to the fact that the vehicle is towed is effectively prevented. The wheels rotate to drive the motor rotor to rotate to generate induced current to damage the motor and the controller, and the service life of the motor is prolonged.
本发明提供一种驱动电机防对拖装置、电动车辆,其中的驱动电机防对拖装置,包括第一连接件、第二连接件以及连接切换件,其中,第一连接件用于与驱动电机的动力输出轴连接,第二连接件用于与车轮减速机构的动力输入轴连接,连接切换件具有同时与第一连接件及第二连接件啮合的动力传动位置以及至少与第一连接件及第二连接件中任一脱离啮合的防对拖位置,连接切换件能够两个位置之间切换。本发明在车辆故障需要拖车处理时,可以将连接切换件由动力传动位置切换至防对拖位置,使车轮减速机构与驱动电机的动力输出轴脱离传动连接,有效防止电机因为车辆被拖行,车轮转动带动电机转子旋转产生感应电流损伤电机以及控制器,提高电机的使用寿命。
