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.

    本发明涉及一种适用于军用越野车的整体式双回路转向器总成,属汽车液压助力转向器技术领域。转向壳体内设置有装配转向螺母形成的互不连通的左油腔和右油腔,阀套与输入轴之间设置有阀套油槽,转向螺杆与输入轴之间设置有螺杆油槽,螺杆油槽上方的转向壳体上设置有主阀进油道,螺杆油槽下方的转向壳体上设置有主阀回油道,主阀回油道和主阀进油道分别与螺杆油槽连通,螺杆油槽通过连通孔分别与左油腔和右油腔连通,该转向器总成具有安全可靠和具备应急转向能力的特点,解决了现有转向器存有的转向器存有的安全系数低和转向容易失效的问题,满足了汽车液压助力转向器的安全需求。
