A steering device (100a, 100b, 200a, 200b, 310, 410) for a motor vehicle (400), in particular for use in a steer-by-wire system (300, 402), comprises a steering handle (110) that is rotatable about an axis (A) of the steering device (100a, 100b, 200a, 200b, 310, 410), and a handle (110) that is rotatable about an axis (A) of the steering device (100a, 100b, 200a, 200b, 310, 410). And a recovery torque generating device (120a, 120b, 220a, 220b) engaged with the steering handle (110) and configured to generate a torque that at least partially counteracts rotation of the steering handle (110). The recovery torque generating device (120a, 120b, 220a, 220b) includes: a motor (130) having a hollow core (136) coaxial with an axis (A) of the steering device (100a, 100b, 200a, 200b, 310, 410); and a gear (140a, 140b, 240a, 240b) engaged with the motor (130) and configured to transmit torque generated by the motor (130) to the steering handle (110). The gear (140a, 140b, 240a, 240b) has a hollow central region (142, 242) coaxial with the axis (A) of the steering device (100a, 100b, 200a, 200b, 310, 410) and a gear ratio in the range of 20: 1 to 100: 1.
一种用于机动车辆(400)的转向装置(100a;100b;200a;200b;310;410),特别是用于线控转向系统(300;402)中,包括:转向手柄(110),绕转向装置(100a;100b;200a;200b;310;410)的轴线(A)是可旋转的;以及恢复扭矩产生装置(120a;120b;220a;220b),其与转向手柄(110)接合,并且被配置为产生至少部分地抵消转向手柄(110)的旋转的扭矩。恢复扭矩产生装置(120a;120b;220a;220b)包括:马达(130),具有与转向装置(100a;100b;200a;200b;310;410)的轴线(A)同轴的中空芯(136);以及齿轮(140a;140b;240a;240b),其与马达(130)接合并且被配置为将由马达(130)产生的扭矩传递到转向手柄(110)。齿轮(140a;140b;240a;240b)具有与转向装置(100a;100b;200a;200b;310;410)的轴线(A)同轴的中空中心区域(142;242)和在20:1至100:1的范围内的齿轮比。
