The hydraulic steering gear comprises a hydraulic steering gear body, a cycloid type motor is arranged in the hydraulic steering gear body, the cycloid type motor comprises an outer valve body and an inner valve body, the inner valve body is arranged in the outer valve body in a sleeved mode, one end of the inner valve body is connected with an output shaft, and the other end of the inner valve body is connected with an output shaft. And the output shaft extends to the outer side of the outer valve body. According to the hydraulic steering gear suitable for the low steering torque of the electric fork lift truck, the sealing groove is formed in the rotor, and the sealing ring and the O-shaped ring are embedded in the sealing groove, so that the sealing performance of an L cavity, an R cavity and a T cavity of the full-hydraulic steering gear provided with a stator and rotor pair of the stator and the rotor is improved; on the premise that sealing is guaranteed, the rotor and the stator rotate more smoothly, mechanical resistance is reduced, and therefore low-torque steering of the steering gear is achieved, and when the steering gear rotates a forklift, steering is light, and fatigue is not prone to happening after long-time operation.

    本申请公开了一种适用于电瓶叉车低转向扭矩的液压转向器,包括液压转向器本体,所述液压转向器本体内设有摆线式马达,所述摆线式马达包括外阀体和内阀体,所述内阀体套设在外阀体的内部,所述内阀体的一端连接有输出轴,所述输出轴延伸至外阀体的外侧。一种适用于电瓶叉车低转向扭矩的液压转向器,通过在转子上开设密封槽,并在密封槽内嵌设密封环和O型圈,从而增加安装有本申请定子、转子的定转子副的全液压转向器的L腔、R腔与T腔的密封性能,在保证密封的前提下使转定子转动更加顺滑,减小机械阻力,从而使转向器实现低扭矩转向,在转向器转动叉车的时候,转向比较轻,长时间操作不容易疲劳。
