The invention relates to the technical field of steering equipment for vehicles, and provides a circulating ball type electric power steering gear which comprises a mechanical steering gear, a speed reducer, an integrated motor controller and a sensor. The mechanical steering gear is provided with a steering gear shell and a steering screw, and the speed reducer is provided with a speed reducer shell. The steering gear shell and the speed reducer shell are fixed in a detachable connection mode. A steering input shaft and a worm wheel shaft are arranged in the speed reducer and are flexibly connected through an elastic torsion bar; and a sensor is arranged at the joint of the input end of the steering input shaft and the output end of the worm wheel shaft. The Hela torque sensor capable ofoutputting a torque signal and a corner signal at the same time is adopted, induction is more sensitive, and the signals are more stable and reliable.

    本发明涉及车辆用转向设备的技术领域,提供了一种循环球式电动助力转向器,包括机械转向器、减速器、一体化电机控制器、传感器;所述机械转向器设置有转向器壳体、转向螺杆,所述减速器设置有减速器壳体;所述转向器壳体、减速器壳体之间通过可拆卸连接方式固定;所述减速器内部设置有转向输入轴与蜗轮轴,所述转向输入轴与蜗轮轴之间通过弹性扭杆柔性连接;所述转向输入轴的输入端、所述蜗轮轴的输出端之间的连接处安装传感器。本发明采用可同时输出扭矩信号和转角信号的海拉扭矩传感器,感应更灵敏,信号更稳定可靠。
