According to the distributed automobile redundant steering system, a second magnetic part is connected with a coil, the coil is connected with a first motor and a second motor through wire harnesses, when the coil is powered on, the first magnetic part and the second magnetic part are attracted, and when the coil is powered off, the first magnetic part and the second magnetic part are disconnected. The first motor controls the first steering lead screw to move axially through the first speed reduction assembly and controls the wheel connected with the first steering lead screw to steer, the second motor controls the second steering lead screw to move axially through the second speed reduction assembly and controls the wheel connected with the second steering lead screw to steer, and the first motor and the second motor work independently. When the first motor fails, the second motor charges the coil, the second magnetic piece generates a magnetic field, the first magnetic piece is attracted, the first steering lead screw moves in the axial direction, the wheel connected with the first steering lead screw steers, and it is ensured that under the condition that one motor fails, the other motor can achieve double-side power assisting.
本发明公开了分布式汽车冗余转向系统,第二磁性件连接有线圈,线圈分别通过线束与第一电机和第二电机连接,当所述线圈通电时,第一磁性件与第二磁性件相吸附,当所述线圈断电时,第一磁性件与第二磁性件断开。第一电机通过第一减速组件控制第一转向丝杆轴向运动,控制与第一转向丝杆连接的轮子进行转向,第二电机通过第二减速组件控制第二转向丝杆轴向运动,控制与第二转向丝杆连接的轮子进行转向,第一电机和第二电机各自独立工作,当第一电机失效,第二电机对线圈充电,第二磁性件产生磁场,对第一磁性件进行吸附,使第一转向丝杆轴向移动,与第一转向丝杆连接的轮子进行转向,确保在其中一个电机失效的情况下,另一个电机能实现双侧助力。
