The invention discloses a decoupling device, an electric drive assembly and a vehicle, the decoupling device is arranged between a driving motor and a wheel of the vehicle, the decoupling device comprises a decoupling motor, a rotating part and a moving part, the rotating part is connected to the decoupling motor and can rotate under the driving of the decoupling motor, and the moving part is connected to the rotating part and can rotate under the driving of the decoupling motor. Rotation of the rotating piece can drive the moving piece to move. The moving part is provided with a first side and a second side which are respectively provided with the driving motor and the wheel, the decoupling device is constructed to have a decoupling state and a coupling state, the moving part moves to separate the driving motor from the wheel in the decoupling state, and the moving part is combined with the driving motor and the wheel to realize torque transmission in the coupling state. When the vehicle is in the sliding working condition, the decoupling device is set to be in the decoupling state, the driving motor and the wheels are separated through the decoupling device, the driving motor and the differential do not rotate so as to reduce vibration noise, and the NVH performance of the vehicle can be improved.

    本发明公开了一种解耦装置、电驱总成和车辆,解耦装置装设在车辆的驱动电机和车轮之间,解耦装置包括:解耦电机、转动件和移动件,转动件连接于解耦电机,可在解耦电机的驱动下转动,移动件连接于转动件,转动件的转动可带动移动件移动。移动件具有分别设置驱动电机和车轮的第一侧和第二侧,解耦装置被构造成具有解耦状态和耦合状态,在解耦状态移动件发生移动使驱动电机与车轮分离,在耦合状态移动件与驱动电机、车轮结合以实现力矩传递。当车辆处于滑行工况时,将解耦装置设为解耦状态,解耦装置将驱动电机与车轮分离,驱动电机和差速器不转动以降低振动噪声,可改善车辆的NVH性能。
