Closed loop feedback circle drive systems for motor graders

ZELL ADAM B / ROGERS KATHERINE S

The invention discloses a closed loop feedback circle drive system for a motor grader. The closed loop feedback circle includes an operator input device, a blade, and a multi-speed hydraulic motor having a motor output shaft. The motor output shaft is mechanically linked to blade such that motor output shaft rotation drives rotation of the blade about a blade rotation axis. A controller is operably coupled to the operator input device and to the multi-speed hydraulic motor. The controller is configured to: (i) receive blade rotation commands via the operator input device to rotate the blade about the rotation axis in a commanded manner; and (ii) control the multi-speed hydraulic motor to implement the blade rotation commands, while repeatedly adjusting the rotational speed of the motor output shaft to reduce variations in a rotational velocity of the blade due to changes in blade loading conditions occurring during motor grader operation.

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。
