    • A power steering apparatus of rack-and-pinion type comprising an input shaft steered by a driver, an output shaft operatively connected to a rack bar through a rack-and-pinion gear mechanism, a hydraulic cylinder operatively connected to the rack bar, and a rotary valve operatively connected to the input shaft. The steering apparatus further comprises an intermediate rotary member disposed between the input shaft and output shaft for rotation about an axis offset from the rotational axis of the output shaft, and a reduction gear mechanism arranged between the rotary valve and the intermediate rotary member. A cam mechanism is disposed between the intermediate rotary member and the output shaft for transmitting the rotation of the intermediate rotary member to the output shaft. The cam mechanism is composed of a cam groove formed on one of the intermediate rotary member and output shaft, and a follower roller provided on the other of the intermediate rotary member and output shaft to be engaged with the cam groove.
    • 一种齿条齿轮式动力转向装置,包括由驾驶员转向的输入轴,通过齿条和小齿轮机构可操作地连接到齿条的输出轴,可操作地连接到齿条的液压缸,以及 可操作地连接到输入轴的旋转阀。 转向装置还包括设置在输入轴和输出轴之间的中间旋转构件,用于围绕输出轴的旋转轴线偏移的轴线旋转,以及设置在旋转阀和中间旋转构件之间的减速齿轮机构。 凸轮机构设置在中间旋转构件和输出轴之间,用于将中间旋转构件的旋转传递到输出轴。 凸轮机构由形成在中间旋转构件和输出轴中的一个上的凸轮槽以及设置在中间旋转构件和与凸轮槽接合的输出轴中的另一个的从动辊构成。

    • In a front wheel steering apparatus including an input shaft arranged to be rotated by the driver's steering effort applied thereto, an output member operatively connected to a set of steerable front road wheels by use of a steering linkage and an interconnecting mechanism for operatively interconnecting the input shaft to the output member, an axial projection is provided on an input end of the input shaft in parallel with the rotation axis of the input shaft and at a position radially displaced a predetermined distance from the rotational axis of the input shaft, a cam follower is rotatably mounted on the axial projection, and a cam shaft is arranged in parallel with the input shaft to be applied with the steering effort for effecting rotation of the input shaft. The cam shaft has a flange portion formed with a radial cam groove for engagement with the cam follower, and the rotational axis of the cam shaft is located at a position radially displaced a smaller distance from the rotational axis of the input shaft smaller distance than the predetermined distance between the rotation axis of the input shaft and the axial projection.
    • 在包括输入轴的前轮转向装置中,所述输入轴被布置成通过施加到其上的驾驶员的转向力来旋转,输出构件通过使用转向联动装置和互连机构可操作地连接到一组可操纵的前轮,用于将输入 轴到输出构件,在输入轴的输入端上平行于输入轴的旋转轴线并在与输入轴的旋转轴线径向偏移预定距离的位置处设置轴向突起,凸轮从动件 可旋转地安装在轴向突起上,并且凸轮轴与输入轴平行地布置以施加转向力,以实现输入轴的旋转。 凸轮轴具有形成有用于与凸轮从动件接合的径向凸轮槽的凸缘部分,并且凸轮轴的旋转轴线位于径向偏移距离输入轴的旋转轴线更小的位置,距离小于 输入轴的旋转轴线与轴向突出部之间的预定距离。
