    • A hand-operated dual joystick for a motor grader is disclosed. The dual joystick comprises a first joystick having a ledge and a switch, and a second joystick that is significantly smaller than the first joystick. The second joystick is mounted to the ledge of the first joystick. The first joystick is moveable along a first axis and a second axis that are perpendicular to each other. In addition, the first joystick is rotatable about a third axis that is perpendicular to the first axis and to the second axis. The second joystick is moveable along the first axis and the second axis. Movement of the first joystick and the second joystick is used to control a plurality of motor grader functions. The dual function joystick permits an operator to control a plurality of the motor grader functions from a single location thus reducing operator fatigue.
    • 公开了一种用于平地机的手动双重操纵杆。 双重操纵杆包括具有凸缘和开关的第一操纵杆和明显小于第一操纵杆的第二操纵杆。 第二操纵杆被安装到第一操纵杆的凸缘上。 第一操纵杆可沿着彼此垂直的第一轴和第二轴移动。 另外,第一操纵杆可围绕垂直于第一轴线和第二轴线的第三轴线旋转。 第二操纵杆可沿第一轴和第二轴移动。 使用第一操纵杆和第二操纵杆的移动来控制多个自动平地机功能。 双功能操纵杆允许操作者从单个位置控制多个电动平地机功能,从而减少操作者的疲劳。

    • A lever bank for implement controls on large construction or agricultural vehicles has a "home" position for operation of the levers. One of the levers has a handle which is larger than the handles of the other levers. This large handle provides a rest position for the operator such that the operator will know the location of the other handles relative to this one handle. The operator may thus rest a hand on this one lever, and know where the other levers are relative to the one lever without looking away from the direction of movement of the vehicle. This simplifies operation of the vehicle.
    • 大型建筑或农用车辆实施控制的杠杆库具有操纵杠杆的“家”位置。 其中一个杠杆的手柄大于其他杠杆的手柄。 这个大把手为操作人员提供一个休息位置,这样操作者就可以知道其他手柄相对于这个手柄的位置。 因此,操作者可以将手放在该一个杠杆上,并且知道其他杠杆相对于一个杠杆的位置,而不用远离车辆的运动方向。 这简化了车辆的操作。

    • A dual steering system for controlling the steering of a motor grader is disclosed. The first portion of the steering system comprises a steering wheel connected through a hydraulic steering valve to hydraulic right and left steering cylinders, which are connected to the right front tire and left front tire, respectively. Rotation of the steering wheel causes rotation of the front tires. A second portion of the steering system comprises a first button and a second button that are mounted to a control lever. Actuation of the first button sends a first electrical input signal and actuation of the second button sends a second electrical input signal to an electronic control computer. The electronic control computer generates control signals in response to the electrical input signals and transmits these control signals to a plurality of electro-hydraulic actuators. Actuation of an electro-hydraulic actuator by one of the control signals leads to actuation of the right steering cylinder and the left steering cylinder thereby causing rotation of the front wheels of the grader in one of two directions. Thus, the direction of travel of a motor grader can be controlled by one of two steering systems, one of which permits an operator to maintain contact with a control lever while adjusting the steering of the motor grader.
    • 公开了一种用于控制平地机的转向的双转向系统。 转向系统的第一部分包括通过液压转向阀连接到液压左右转向油缸的方向盘,其分别连接到右前轮胎和左前轮胎。 方向盘的旋转引起前轮胎的旋转。 转向系统的第二部分包括安装到控制杆的第一按钮和第二按钮。 第一按钮的致动发送第一电输入信号,并且第二按钮的致动将第二电输入信号发送到电子控制计算机。 电子控制计算机响应于电输入信号产生控制信号,并将这些控制信号发送到多个电动液压致动器。 通过控制信号中的一个致动电动液压致动器,导致右转向油缸和左转向油缸的致动,从而使得分级机的前轮在两个方向中的一个方向上的旋转。 因此,电动平地机的行进方向可以由两个转向系统之一来控制,其中一个转向系统允许操作员在调节自动平地机的转向的同时与控制杆保持接触。
