    • A torsion bar device includes a torsion bar having a torsional portion, an upper connecting portion associated with an input shaft, and a lower connecting portion associated with an output shaft; a first cylinder for encompassing the torsional portion, one end of the first cylinder being connected to one of the upper and lower connecting portions, and the other end of the first cylinder extending in the longitudinal direction of the torsion bar to the other connecting portion of the torsion bar; a second cylinder for encompassing and being connected to the other one of the upper and lower connecting portions of the torsion bar; a first supporting member for supporting the torsion bar at the other end of the first cylinder in a circumferential direction of the torsion bar; a second supporting member for supporting the torsion bar in the circumferential direction at a portion of the second cylinder where the second supporting member is aligned with the first supporting member; and an elastic member for elastically restoring the alignment of the first and second supporting members by applying a force in a direction opposite to a torsionally stressed circumferential direction of the torsion bar when a steering wheel is turned so as to regain the original neutral position of the steering wheel.
    • 扭杆装置包括具有扭转部分的扭杆,与输入轴相关联的上连接部分和与输出轴相关联的下连接部分; 用于包围所述扭转部分的第一气缸,所述第一气缸的一端连接到所述上连接部分和所述下连接部分中的一个,所述第一气缸的另一端在所述扭杆的纵向方向上延伸到所述扭杆的另一连接部分 扭杆; 用于包围并连接到扭杆的上连接部分和下连接部分中的另一个的第二圆筒; 第一支撑构件,用于在所述扭杆的圆周方向上将所述扭杆支撑在所述第一气缸的另一端; 第二支撑构件,用于在所述第二支撑构件与所述第一支撑构件对准的所述第二气缸的一部分处在所述周向方向上支撑所述扭杆; 以及弹性构件,用于通过在方向盘转动时沿与扭杆的扭转应力的周向方向相反的方向施加力来弹性地恢复第一和第二支撑构件的对准,以便重新获得扭矩杆的原始中立位置 方向盘。

    • A vehicle steering system including: (a) a steering operation member; (b) a movement-amount variably transmitting device including: (b-1) a housing fixed to a vehicle body; (b-2) a differential mechanism including (i) a first element connected to the steering operation member, (ii) a second element movable relative to the first element, and (iii) a third element engaged with the first and second elements; and (b-3) a drive source for moving the third element, such that an amount of relative movement of the first and second elements is changeable depending on an amount of movement of the third element; and (c) a wheel turning device connected to the second element to turn a vehicle wheel. The movement-amount variably transmitting device further includes (b-4) a third-element-movement inhibiting device for inhibiting movement of the third element. The steering system further includes (d) a third-element-movement inhibition cancelling device for cancelling inhibition of the movement of the third element.
    • 一种车辆转向系统,包括:(a)转向操作构件; (b)运动量可变发送装置,包括:(b-1)固定到车体的壳体; (b-2)包括(i)连接到转向操作构件的第一元件,(ii)可相对于第一元件移动的第二元件的差速机构,以及(iii)与第一元件和第二元件接合的第三元件; 和(b-3)用于移动第三元件的驱动源,使得第一和第二元件的相对移动量可以根据第三元件的移动量而改变; 和(c)连接到第二元件以转动车轮的车轮转向装置。 移动量可变发送装置还包括(b-4)用于抑制第三元件的移动的第三元件移动禁止装置。 转向系统还包括(d)用于消除对第三元件的运动的抑制的第三元件移动抑制消除装置。
