The invention relates to a double-power input type transmission for a caterpillar. The double-power input type transmission comprises a box body. The box body is provided with a power input mechanism, a double-power input mechanism, a middle transmission mechanism, a differential speed type drive mechanism, a left caterpillar band drive mechanism, a right caterpillar band drive mechanism and a power output mechanism. The power input mechanism is connected with the double-power input mechanism and the power output mechanism. The double-power input mechanism is connected with the differential speed type drive mechanism through the middle transmission mechanism. The differential speed type drive mechanism is connected with the left caterpillar band drive mechanism and the right caterpillar band drive mechanism. According to the double-power input type transmission, a mechanical and hydraulic parallel type double-power input device and a differential speed type steering mechanism capable of controlling gear rings of planetary gear mechanisms on the two sides of a drive wheel through external power to rotate forwards and reversely, the drive efficiency and control convenience of the caterpillar can be improved effectively, steering accuracy is improved, and the defects that an existing caterpillar is low in transmission efficiency and large in traveling side deflection resistance and cannot be controlled easily, and the sludge blocking problem is serious when the caterpillar conducts steering at the edge of a field are overcome.
