The invention provides a transmission mechanism of a crawler-type machine. The transmission mechanism of the crawler-type machine comprises a power input device, a first hydrostatic transmission system, a second hydrostatic transmission system, a first planetary transmission mechanism, a second planetary transmission mechanism, a first power output device, a second power output device and a reversing device, wherein the first hydrostatic transmission system and the second hydrostatic transmission system are connected with the power input device, the first planetary transmission mechanism and the second planetary transmission mechanism are in transmission connection with the first hydrostatic transmission system and the second hydrostatic transmission system, the first power output device is connected with the first planetary transmission mechanism, the second power output device is connected with the second planetary transmission mechanism, and the reversing device is connected with the first planetary transmission mechanism or the second planetary transmission mechanism. According to the transmission mechanism of the crawler-type machine, high precision equipment is not needed for controlling the power output quantity of the two sides of the machine, and the cost is greatly reduced; meanwhile, due to the fact that the mechanical transmission efficiency usually can reach over 90%, waste of energy is avoided. Therefore, by means of the transmission mechanism of the crawler-type machine, the problems that in the prior art, the cost of the transmission mechanism is high, and the efficiency is low can be solved.
