The invention discloses a dual-power input and differential type steering tracked vehicle transmission. A power input mechanism, a dual-power input mechanism, a middle transmission mechanism, a differential type driving mechanism and a PTO power output mechanism are all mounted on a box body. A left caterpillar driving mechanism and a right caterpillar driving mechanism are the same in structure and are symmetrically mounted on the two sides of the box body. The power input mechanism is connected with the PTO power output mechanism and the dual-power input mechanism. The dual-power input mechanism transmits power and is connected with the middle transmission mechanism. The middle transmission mechanism is connected with the differential type driving mechanism, and the differential type driving mechanism is used for outputting the power to drive the left caterpillar driving mechanism and the right caterpillar driving mechanism. The problem of direct mechanical transmission and hydraulic stepless combination is solved by switching a combination sleeve, and the transmission efficiency and the control performance of a tracked vehicle are effectively improved. Meanwhile, a hydraulic motor controls planet carrier gears of planet gear mechanisms on the two sides of a driving wheel to rotate forwardly and reversely, so that the rotating speeds of the two ends of a traveling and driving power output shaft are changed, and accordingly steering is achieved.
