Abstract: Disclosed are an electric drive assembly and an electric device. The electric drive assembly includes a motor, a speed shifting mechanism connected to the motor, and a cooling system configured to supply lubricating oil to the motor and the speed shifting mechanism in sequence. With the cooling system provided, lubricating oil is sequentially supplied to the motor and the speed shifting mechanism, reducing the loss of the cooling capacity of lubricating oil in the speed shifting mechanism, improving the cooling efficiency and the utilization rate of the cooling capacity, and reducing the loss.
