The invention relates to the technical field of vehicle steering, in particular to a dual-redundancy drive-by-wire electric steering system. The invention provides a dual-redundancy drive-by-wire electric steering system which comprises a steering axle, a connecting rod mechanism, a steering arm, a speed reducer, a connecting flange, a steering motor and a steering controller, the steering controller controls and drives the steering motor, the steering motor drives the speed reducer to rotate, and the speed reducer drives the steering arm to swing. And the steering axle is driven by the connecting rod mechanism to steer. According to the dual-redundancy drive-by-wire electric steering system, a drive-by-wire electric steering mode is adopted, energy conservation and environmental protection are achieved, and the cost and the installation difficulty are reduced; the overall structure is compact, installation is convenient, pipeline connection is not needed, and the device is particularly suitable for multi-shaft steering system arrangement; the double-winding motor and the RV speed reducer are adopted, the service life is long, and steering reliability and accuracy are guaranteed.

    本发明涉及车辆转向技术领域,更具体的说,涉及一种双冗余线控电动转向系统。本发明提供了一种双冗余线控电动转向系统,包括转向车桥、连杆机构、转向臂、减速器、连接法兰、转向电机以及转向控制器:转向控制器控制驱动转向电机,转向电机带动减速器转动,减速器带动转向臂摆动,通过连杆机构驱动转向车桥进行转向。本发明提出的一种双冗余线控电动转向系统,采用线控电动转向方式,节能环保,降低成本及安装难度;整体结构紧凑,安装方便,无需管路连接,特别适用于多轴转向系统布置;采用双绕组电机及RV减速器,寿命长,保证转向可靠性及准确性。
