According to the novel double-side-cover hydraulic power-assisted circulating ball steering gear assembly, a steering screw assembly serves as a hydraulic control valve to control flowing of hydraulic oil; the steering nut assembly and the steering screw assembly are matched through a steel ball I to form a pin roller screw pair, the steering screw assembly and the valve body assembly are limited through an angular contact ball bearing composed of an outer ring and a steel ball II, and double tooth parts between the steering nut assembly and the steering arm shaft are meshed to form a rack-gear transmission pair. The left side cover assembly and the right side cover assembly are fixed on the steering arm shaft through the locking nut, the anti-attrition pad is arranged between the left side cover assembly and the right side cover assembly and the steering arm shaft, the locking nut is axially limited, and the steering arm shaft is assembled in the shell assembly. The problem that a traditional single-side-cover hydraulic power-assisted circulating ball steering gear is large in space boundary dimension is solved.

    一种新型双侧盖液压助力循环球转向器总成,转向螺杆总成作为液压控制阀,控制液压油流动;转向螺母总成与转向螺杆总成通过钢球Ⅰ配合组成滚柱螺旋副,转向螺杆总成与阀体总成通过外圈和钢球Ⅱ组成的角接触球轴承限位,转向螺母总成与转向臂轴之间双方齿部啮合形成齿条‑齿轮传动副。左右侧盖总成通过锁紧螺母,固定在转向臂轴上,左右侧盖总成与转向臂轴中间设有减磨垫,也锁紧螺母轴向限定,转向臂轴装配在在壳体总成中。本发明解决了传统单侧盖液压助力循环球转向器存在的空间外形尺寸大的问题。
