Closed-loop feedback cycle drive system for motor grader
A closed loop feedback cycle drive system for a motorized grader includes an operator input device, a blade, and a multi-speed hydraulic motor having a motor output shaft. The motor output shaft is mechanically coupled to the blade such that rotation of the motor output shaft drives rotation of the blade about the blade rotation axis. A controller is operably coupled to the operator input device and the multi-speed hydraulic motor. The controller is configured to: (i) receive a blade rotation command via the operator input device to rotate the blade about the axis of rotation in a commanded manner; and (ii) controlling the multi-speed hydraulic motor to execute the blade rotation command while repeatedly adjusting the rotational speed of the motor output shaft to reduce changes in blade rotational speed due to changes in blade load conditions occurring during operation of the motorized grader.
本发明公开了一种用于机动平地机的闭环反馈循环驱动系统，包括操作者输入装置、铲刀和具有马达输出轴的多速液压马达。马达输出轴机械地连结到铲刀，使得马达输出轴的旋转驱动铲刀绕铲刀旋转轴线的旋转。控制器以能够操作的方式联接到操作者输入装置和多速液压马达。所述控制器被配置为：(i)经由所述操作者输入装置接收铲刀旋转命令，以使所述铲刀以所命令的方式绕所述旋转轴线旋转；以及(ii)控制多速液压马达以执行铲刀旋转命令，同时重复地调节马达输出轴的转速以减小由于在机动平地机操作期间所发生的铲刀负载状况的变化而引起的铲刀转速的变化。
