The invention relates to an integrated double-loop steering gear assembly suitable for a military off-road vehicle, and belongs to the technical field of automobile hydraulic power steering gears. A left oil cavity and a right oil cavity which are formed by assembling a steering nut and are not communicated with each other are formed in the steering shell, a valve sleeve oil groove is formed between a valve sleeve and an input shaft, a screw oil groove is formed between a steering screw and the input shaft, a main valve oil inlet channel is arranged on the steering shell above the screw oil groove, a main valve oil return channel is arranged on the steering shell below the screw oil groove, and the main valve oil return channel and the main valve oil inlet channel are respectively communicated with the screw oil groove. The steering gear assembly has the advantages of being safe, reliable and capable of achieving emergency steering, the problems that a steering gear of an existing steering gear is low in safety coefficient and steering is prone to losing efficacy are solved, and the safety requirement of the automobile hydraulic power steering gear is met.
