摘要： A track type tractor incorporates control over lift, tilt, angle and pitch into an implement control joystick. The pitch cylinder and the tilt cylinder share segments of the hydraulic circuit, and a diverter valve prioritizes pitch control over tilt control in the rare occurrence when the operator is requesting both tilt and pitch changes to the dozer blade. Angle control and pitch control may be accomplished by finger controllers incorporated into the implement control joystick. Thus, the operator can control the dozer blade in four degrees of freedom without losing contact with the implement control joystick.
摘要翻译： 轨道式拖拉机将升力，倾斜，角度和俯仰控制结合到工具控制操纵杆中。 俯仰气缸和倾斜气缸共享液压回路的段，并且当操作者要求对推土铲叶片的倾斜和俯仰变化时，分流阀优先考虑在倾斜控制上的俯仰控制。 角度控制和俯仰控制可以通过结合到工具控制操纵杆中的手指控制器来实现。 因此，操作者可以以四个自由度控制推土铲，而不会损失与工具控制操纵杆的接触。
