An electric drive assembly is provided with oil/water dual cooling that includes a motor module, a gearbox module, a water cooling module and an oil cooling module. The oil cooling module has three oil cooling passages, and introduces the lubricating oil in the gearbox into the front and rear windings of the motor, thereby improving the cooling performance of the motor, eliminating the need for a motor shaft oil seal, reducing the cost of the drive assembly and improving the transmission efficiency. The water cooling module cools the motor housing through the motor water jacket, and cools the lubricating oil in the gearbox housing through the heat sink at the bottom of the gearbox, thereby solving the heat dissipation problem when the gearbox operates at high speed constantly, and thus improving the service life and reliability of the gear and bearing.
