The invention belongs to the technical field of commercial vehicles, and relates to a drive-by-wire steering gear for a commercial vehicle. The drive-by-wire steering gear comprises a first steering gear and a second steering gear, the first steering gear and the second steering gear are connected with the right side tire and the left side tire through steering axles correspondingly and each comprise an EPS controller, a power-assisted motor, a first steering gear shell, a lead screw nut transmission mechanism, a worm gear arranged outside the lead screw nut transmission mechanism and a worm matched with the worm gear, and one end of the worm is connected with the power-assisted motor. A traditional T-shaped steering axle mechanism is omitted, the two steering gears which are symmetrically arranged and work independently are adopted to assist a left steering tire and a right steering tire respectively, steering sideslip is avoided, and tire abrasion is reduced. Meanwhile, by changing the arrangement mode of the sensor, the steering gear is more sensitive in response and more instant in steering signal feedback, and the steering gear is applied to the field of unmanned driving and has wide application prospects.
本发明属于商用车技术领域,涉及一种商用车线控转向器包括相互独立工作的第一转向器和第二转向器;第一转向器和第二转向器分别通过转向桥与右侧轮胎、左侧轮胎相连,第一转向器和第二转向器均包括EPS控制器,助力电机,第一转向器壳体,丝杠螺母传动机构,设置在所述丝杠螺母传动机构外的蜗轮,与蜗轮配合且一端连接助力电机的蜗杆,第二转向器壳体,拉杆,球销机构,位移传感器,本发明取消传统的T形转向桥机构,采用对称布置的两个独立工作的转向器,分别对左右转向轮胎助力,避免转向侧滑,减少轮胎磨损。同时,更改传感器的布置方式,使转向器的响应更灵敏,反馈转角信号更即时,应用于无人驾驶领域,有广泛的应用前景。
