The invention discloses a hybrid four-gear transmission adopting double long-wheelbase motors. The transmission comprises a solid input shaft, a hollow input shaft, double clutches, an output shaft, adifferential, a first transmission mechanism and a second transmission mechanism, wherein the first transmission mechanism is arranged between the solid input shaft and the output shaft; and the second transmission mechanism is arranged between the hollow input shaft and the output shaft. The transmission further comprises a first motor and a second motor, wherein the first motor is connected with the differential through the second transmission mechanism, the second motor is directly connected with the differential, and the first motor and the second motor adopt high-speed high-efficiency long-wheelbase motors with the same wheelbase. According to the transmission, the two motors are arranged between the two ends of the solid input shaft in the axial direction, and the first motor is asclose to the input shafts as possible in the radial direction, so that the position of the differential is approximate to the position of a traditional transmission, the space change of an auxiliary frame of the whole vehicle is avoided as much as possible, and the length of a short half shaft of the differential is ensured to ensure the design and configuration of the included angle of a ball cage.
