The invention relates to the technical field of automobile steering, and provides a torque feedback unit and a steer-by-wire system. The torque feedback unit is applied to the steer-by-wire system and comprises a motor and a worm shaft coaxially connected with the motor, a torque measuring part is arranged at the end, away from the motor, of the worm shaft, and the torque measuring part is a non-functional component of the torque feedback unit. The torque measuring part is clamped to transmit the output torque of the motor when detecting the output torque of the motor. According to the invention, the tail end of the worm shaft of the torque feedback unit is provided with the torque measuring part as a non-functional part, and the torque measuring part can be clamped by the torque detection device to transmit the output torque of the motor when the output torque of the motor is detected, so that the detection of the output torque of the motor does not affect the functional part of the torque feedback unit. Therefore, the normal function of the torque feedback unit is realized.

    本发明涉及汽车转向技术领域,提供一种扭矩反馈单元和线控转向系统。扭矩反馈单元应用于线控转向系统,包括电机和与所述电机同轴连接的蜗杆轴,其中:所述蜗杆轴的远离所述电机的端部设置有扭矩测量部,所述扭矩测量部为所述扭矩反馈单元的非功能部件,所述扭矩测量部于检测所述电机的输出扭矩时被夹持以传递所述电机的输出扭矩。本发明在扭矩反馈单元的蜗杆轴的尾端设置有作为非功能部件的扭矩测量部,扭矩测量部能够在检测电机的输出扭矩时被扭矩检测装置夹持以传递电机的输出扭矩,使对电机的输出扭矩的检测不会影响扭矩反馈单元的功能部件,从而确保扭矩反馈单元的正常功能实现。
