The invention relates to a dynamic coupling system of a cold-chain logistics truck. The dynamic coupling system comprises an engine, a first motor, a second motor, a first input shaft, a second input shaft, a third input shaft, a first brake, a second brake, a third brake, a clutch, a dynamic coupling gear set, a dynamic coupling gear set shell, a differential mechanism, an automobile half shaft and wheels. The engine is connected with the power coupling gear set through a first input shaft, the first motor is connected with the power coupling gear set through a second input shaft, the second motor is connected with the differential mechanism through a third input shaft, and the clutch is connected with the power coupling gear set and the second motor. Wherein the first brake, the second brake and the third brake respectively brake the first input shaft, the second input shaft and the power coupling gear set; power output by the power coupling gear set is transmitted to the second motor through the clutch and then transmitted to the differential mechanism through the third input shaft, and the divided power drives wheels to run through an automobile half shaft. According to the invention, a single-motor driving mode, a multi-power-source coupling driving mode and an extended-range driving mode can be realized.
