The invention discloses a crank stud type electric recirculating ball steering gear, which adopts motor assistance to replace traditional hydraulic assistance to realize a steering function, and the output torque of a motor passes through a worm gear and worm transmission pair and a ball screw transmission pair. The motor is adopted as a power source of the steering gear, hydraulic elements such as an oil pump, an oil pipe and an oil can are omitted in the whole steering system, parts of the whole vehicle are reduced, installation and debugging are convenient, and cost is reduced. The steering hand force of the steering wheel can be freely adjusted according to the requirements of different working conditions of the whole vehicle, and starting as required can be realized, so that the fuel consumption is greatly reduced.
本发明公开了一种曲柄指销式电动循环球转向器,转向器采用电机助力替代传统液压助力实现转向功能,电机的输出扭矩经蜗轮蜗杆传动副,滚珠丝杠传动副,曲柄滑块传动副进行两次减速增扭以达到轻卡商用车用传统循环球动力转向器的助力效果,通过采用电机作为转向器的动力源,使整个转向系统取消油泵、油管、油壶等液压元件,减少了整车的零部件,便于安装调试,可以根据整车不同工况的需要自由调整方向盘的转向手力的大小,并且可以实现按需启动,从而大大减小燃油消耗。
