    • A vibration-isolating device for a steering wheel of a travelling working vehicle equipped with a wheel steering mechanism includes a first steering shaft (32) that transmits rotational displacement, the first steering shaft being operatively connected to the steering wheel (7); a second steering shaft (33) that transmits rotational displacement, the second steering shaft being operatively connected to the wheel steering mechanism (P, 23); and a vibration-isolating connecting mechanism (31) that operatively connects the first steering shaft (32) and the second steering shaft (33) to each other so that rotational displacement can be transmitted. When the angles of rotational displacement of the first steering shaft (32) and the second steering shaft (33) are within ranges of rotation angles for linearly driving the vehicle, rotational displacement cannot be transmitted between the first steering shaft (32) and the second steering shaft (33).
    • 一种配备有车轮转向机构的行驶工作车辆的方向盘的防振装置,包括:第一转向轴(32),其传递旋转位移,所述第一转向轴与所述方向盘(7)可操作地连接; 第二转向轴(33),其传递旋转位移,所述第二转向轴可操作地连接到所述车轮转向机构(P,23); 以及将第一转向轴(32)和第二转向轴(33)可操作地连接的振动隔离连接机构(31),从而能够传递旋转位移。 当第一转向轴(32)和第二转向轴(33)的旋转位移角度在用于线性驱动车辆的旋转角度的范围内时,旋转位移不能在第一转向轴(32)和第二转向轴 转向轴(33)。
