The invention belongs to the technical field of special vehicle power transmission systems and discloses a dual-power two-way traveling vehicle power transmission system which comprises an engine, a driving motor, a reversing transmission case and a hydraulic transmission. The reversing transmission case comprises a reversing transmission case shell, an elastic coupler, a front input shaft, a motor end input shaft, a shifting fork and an input shaft gear. The motor end input shaft is in transmission connection with the driving motor; two sides of the elastic coupling are respectively connected with the engine and the front input shaft; a sliding sleeve is sleeved on the front input shaft; the hydraulic transmission comprises a torque converter and a multi-gear power gear shifting gearbox, and the torque converter is in transmission connection with the reversing transmission case; the output end of the multi-gear power gear shifting gearbox is in transmission connection with the front steering drive axle and the rear steering drive axle. The sliding sleeve changes gear meshing, and dual-power arrangement is achieved; the hydraulic transmission can complete power transmission and change the power direction, realizes bidirectional normal driving, can load fire rescue operation vehicles in special occasions such as tunnels and the like, and ensures timely and effective rescue.
