    • A vehicle steering system includes a steering input device, a front steering subsystem, a rear steering subsystem, a first force transmission route, a steering control mechanism, a second force transmission route, and a third force transmission route. The front steering subsystem is coupled to front motive members to steer the front motive members based upon movement of a front steering subsystem input shaft. The rear steering subsystem is coupled to rear motive members to steer the rear motive members based upon movement of a rear steering subsystem input shaft. The first force transmission route extends from the steering input device to the front steering subsystem input shaft, wherein force is transmitted from the input device to the front steering subsystem input shaft to steer the front motive members. The steering control mechanism has a movable input member and a movable output member. The movable input member is movable through a first distance without transmitting force to the output member and is movable through a second distance in which force is transmitted to the output member to move the output member. The second force transmission route extends from the steering input device to the input member, wherein force is transmitted from the input device to the input member to move the input member. The third force transmission route extends from the output member to the rear steering subsystem input shaft to move the rear steering subsystem input shaft and to steer the rear motive members.
    • 车辆转向系统包括转向输入装置,前转向系统,后转向子系统,第一力传递路径,转向控制机构,第二力传递路线和第三力传递路径。 前转向子系统联接到前动力构件,以基于前转向子系统输入轴的移动来转向前动元件。 后转向子系统联接到后动元件以基于后转向子系统输入轴的运动来转向后动元件。 第一力传递路径从转向输入装置延伸到前转向子系统输入轴,其中力从输入装置传递到前转向系统输入轴以转向前动动构件。 转向控制机构具有可动输入部件和可动输出部件。 可移动输入构件可以在没有传递力的情况下移动到第一距离到输出构件,并且可移动通过第二距离,其中力被传递到输出构件以移动输出构件。 第二力传递路径从转向输入装置延伸到输入构件,其中力从输入装置传送到输入构件以移动输入构件。 第三力传递路径从输出构件延伸到后转向子系统输入轴,以移动后转向子系统输入轴并引导后动动构件。

    • In a rear suspension system for a four-wheel-steered vehicle, each wheel support is connected to a rear wheel turning rod so that the rear wheel on the wheel support is turned about a king pin axis when the rear wheel turning rod is displaced. Upper and lower arms define the king pin axis, and the rear wheel on the wheel support is turned about the king pin axis in response to displacement of the rear wheel turning rod. The king pin axis is tilted inward from the vertical and intersects the tread of the rear wheel at a point which is longitudinally offset from the point at which a side force acts on the rear wheel during cornering. A coil spring is connected between the wheel support and the vehicle body and restrains vertical motion of the wheel support under the counterforce thereof. The line of action of the counterforce is tilted with respect to the king pin axis so that it is not parallel to the king pin axis, does not intersect the king pin axis and is directed such that the counterforce generates a moment which tends to turn the rear wheel in the direction opposite to the direction in which the moment generated by the side force acting on the outer of the rear wheels tends to turn the outer rear wheel when the vehicle corners.
    • 在用于四轮转向车辆的后悬架系统中,每个车轮支撑件连接到后轮转向杆,使得当后轮转向杆移位时,车轮支撑件上的后轮围绕主销轴线转动。 上臂和下臂限定主销轴线,并且轮支撑件上的后轮响应于后轮转动杆的位移而围绕主销轴线转动。 主销轴从垂直方向向内倾斜,并且在转弯期间在侧向力作用在后轮上的点的纵向偏移的点处与后轮的胎面相交。 螺旋弹簧连接在车轮支撑件和车身之间,并且在其反作用力下限制车轮支撑件的垂直运动。 反作用力的作用线相对于主销轴线倾斜,使得其不平行于主销轴线,不与主销轴线相交并且被引导使得反作用力产生倾向于转动的力矩 后轮在与作用在后轮的外侧上的侧力所产生的力矩相反的方向上倾向于在车辆转弯时使外后轮转动。
