The invention discloses a double-motor recirculating ball type steering system for a heavy commercial vehicle, which comprises a steering wheel, a steering shaft, a steering angle sensor, an auxiliary motor, an electromagnetic clutch, a worm and gear reducing mechanism, a recirculating ball type steering gear, a torque sensor, a main motor, a planetary gear reducer and a control module, and is characterized in that the steering wheel is assembled at the top end of the steering shaft; the torque sensor is assembled on the steering shaft, the recirculating ball type steering gear input shaft is assembled at the bottom end of the steering shaft, the auxiliary motor is connected with the steering gear input shaft through the worm gear reducer, the steering angle sensor is installed on the steering gear input shaft, and the lower end of a steering screw of the recirculating ball type steering gear is connected with the main motor through the planetary gear reducer. The device has the advantages that a hydraulic pump and an oil tank are omitted, and no complex oil way or oil way accessories need to be assembled; due to the dual-motor design, the fault tolerance of the steering system is improved, and the large-torque output requirement of a heavy commercial vehicle is met; and intelligent driving functions such as electric steering and lane keeping can be realized.

    本发明公开了一种用于重型商用车双电机循环球式转向系统,包括转向盘、转向轴、转角传感器、辅电机、电磁离合器、蜗轮蜗杆减速机构、循环球式转向器、转矩传感器、主电机、行星齿轮减速器和控制模块,其特征在于,转向盘装配在转向轴顶端,转矩传感器装配在转向轴上,循环球式转向器输入轴装配在转向轴底端,辅电机通过蜗轮蜗杆减速器与转向器输入轴连接,转向器输入轴上安装有转角传感器,循环球式转向器转向螺杆下端通过行星齿轮减速器与主电机连接。有益效果:取消了液压泵和油罐,无复杂的油路及油路附件需要组装;双电机设计提高了转向系统的容错性,满足重型商用车大转矩输出需求;可实现电动转向、车道保持等智能驾驶功能。
