The present invention relates to a steer-by-wire actuation system for a motorised vehicle comprising: at least two electrical steering motors each comprising a rotor (8a, 8b) and a stator (11a, 11b); a vehicle control unit (VCU), configured to receive a steering command from an input steering device; at least two steering electronic control units (ECU) for controlling a torque or rotational speed output from said at least two electrical motors. The system further comprises: a ball screw (5) and a cooperating ball screw nut (21); and a concentric shaft (7) accommodating said ball screw (5) and a cooperating ball screw nut (21), wherein said at least two rotors (8a, 8b) are adapted to transfer torque and rotational speed to said concentric shaft (7), and wherein said ball screw nut (21) is mechanically connected to said concentric shaft (7), so as to translate the rotational movement from the rotors to a linear reciprocating steering movement of the ball screw (5).

    本发明涉及用于机动车辆的线控转向致动系统,该系统包括:至少两个电动转向马达,每个电动转向马达包括转子(8a,8b)和定子(11a,11b);车辆控制单元(VCU),该车辆控制单元被配置为从输入转向装置接收转向命令;至少两个转向电子控制单元(ECU),用于控制从至少两个电动转向马达输出的扭矩或转速。该系统进一步包括:滚珠丝杠(5)和配合的滚珠丝杠螺母(21);以及容纳滚珠丝杠(5)和配合的滚珠丝杠螺母(21)的同心轴(7),其中至少两个转子(8a,8b)适于将扭矩和转速传递到同心轴(7),并且其中滚珠丝杠螺母(21)被机械地连接到同心轴(7),以便将来自这些转子的旋转运动转换为该滚珠丝杠(5)的线性往复转向运动。
