The invention provides a clutch and motor coupled assembly device which comprises a shell, a motor and a wet clutch. The motor is connected in the shell, and the wet clutch is coupled in the motor; the motor comprises a motor stator, a motor rotor and a support disc; the wet clutch comprises an input shaft and an output shaft; the input shaft penetrates out of the shell and is connected with a vehicle engine, and the two ends of the input shaft are fixedly connected with a motor shell through bearings; the output shaft penetrates out of the shell and is connected with a vehicle speed changer, and the output shaft is further connected with the motor rotor through the support disc. According to the clutch and motor coupled assembly device, the clutch is coupled in the motor, so that the space occupied by a hybrid-power driving device is effectively saved; the existing vehicle engine and the speed changer are reserved, the development difficulty is reduced, and the development cost of a whole vehicle is reduced; and meanwhile, through improvement of the structure of the clutch and the motor, the processing and assembling precision of the device is further improved, and the improvement of the performance of the motor is facilitated.
