The invention discloses a steer-by-wire hand feeling simulation device comprising a steering shaft which is fixedly connected with a steering shaft worm wheel; an output shaft of the motor is connected with the worm; the worm and gear pair is formed by meshing a steering shaft worm gear and a worm; the torsion piece is coaxial with the steering shaft, and the first end of the torsion piece is fixedly connected to the end face of the steering shaft worm gear and used for restraining the steering angle range of the tubular column and enabling the steering wheel to automatically return to the neutral position through torsion; when no external force exists, the torsion piece is in a natural state to enable the hand disc to be in a zero position; the corner position sensor determines a mounting position and a use type according to the type of the motor; wherein the center line of the steering shaft, the motor and the second end of the torsion part keep relative coordinates unchanged in a specified coordinate. According to the steering-by-wire hand feeling simulation device, on the premise that a steering intermediate shaft is not configured and no external assistance exists, the steering angle stroke of the steering-by-wire hand feeling simulation device can be restrained, the steering angle certainty is achieved, and the torque characteristic of a mechanical steering system can be simulated.

    本发明公开了一种线控转向手感模拟装置,包括转向轴,其上固定连接转向轴蜗轮;电机,其输出轴连接蜗杆;蜗轮蜗杆付,其由转向轴蜗轮和蜗杆啮合组成;扭力件,其与转向轴同轴,且其第一端固定连接在转向轴蜗轮端面上,用于约束管柱转角范围并依靠扭力使方向盘自动回到中位;无外力时,扭力件处于自然状态使手盘位于零位;转角位置传感器,其根据电机类型确定安装位置和使用类型;其中,转向轴中线、电机和扭力件第二端在一个指定坐标中保持相对坐标不变。本发明在不配置转向中间轴且没有外部助力的前提下,可以约束线控转向手感模拟装置的转角行程,实现转角确定性,并能模拟机械转向系统力矩特性。
