The utility model relates to the technical field of bulldozers and provides a steering system of a hybrid power bulldozer. The system comprises a vehicle controller, a left motor controller, a right motor controller, a left-side travel motor, a right-side travel motor, a steering handle, a battery energy management module and a power battery. According to the system, the functions of a steering control device and an instant large steering torque and braking energy recovery device of the hybrid power bulldozer are performed, i.e., the fixed steering and the infinitely variable speed type mobile steering of the hybrid power bulldozer are achieved through effective cooperation of the vehicle controller, the steering handle, the left motor controller, the right motor controller, the left-side travel motor and the right-side travel motor, and provision of an instant large steering torque and recovery of energy in a braking process are realized through the vehicle controller, the battery energy management module, the power battery, the left motor controller, the right motor controller, the left-side travel motor and the right-side travel motor, so that the operating efficiency of the hybrid power bulldozer is improved and the fuel saving rate of the hybrid power bulldozer is increased.
