The invention discloses a power transmission system and a vehicle having the power transmission system. The power transmission system comprises a shell, a drive motor, an input shaft, a first clutch, a second clutch, a first planetary gear mechanism, a second planet gear mechanism, an output gear, a main reducer, a differential and a hydraulic control system. The input shaft is connected to the drive motor, the first clutch and the second clutch are arranged on the input shaft, the first clutch is selectively connected with a first sun gear of the first planetary gear mechanism, the second clutch is selectively connected with a second planetary frame of the second planetary gear mechanism, a first planetary frame is fixedly connected with the output gear, a second gear ring is fixedly connected with the first planetary frame, the first sun gear is fixedly connected with a second sun gear, and the hydraulic control system is used for controlling the first clutch and the second clutch to be connected and disconnected. According to the power transmission system, the highly effective range of the drive motor can be effectively used, and the climbing speed is fast.
