An electric transmission system applied to a heavy truck comprises a main circuit topology, the main circuit topology comprises a power supply, the power supply is connected with a main and auxiliary integrated traction converter, the main and auxiliary integrated traction converter comprises a main transmission system and an auxiliary system, the main transmission system comprises a main transmission inversion module and a main transmission traction motor, the auxiliary system comprises an auxiliary system inversion module and a multi-path auxiliary transmission driving motor, and the main transmission system and the auxiliary system share a direct current bus. Compared with a traditional heavy truck transmission system, a main and auxiliary integrated traction converter structure is adopted, mechanical parts of power sources of heat dissipation, mechanical braking and lifting steering of the heavy truck system are effectively reduced, frequency conversion and speed regulation can be conducted on the parts, energy can be effectively saved, and the product efficiency can be effectively improved; the main transmission system cancels a clutch and adopts a mode that the motor directly drives a speed reduction axle, so that the weight can be reduced, and complex operations such as gear shifting are reduced.
