Abstract
Motor graders and circle drives associated with the same. An example work vehicle includes a frame, a circle drive coupled to the frame, moldboard coupled to the circle drive and a planetary gear apparatus including an output shaft configured to mesh with the circle drive to rotate the circle drive relative to the frame.
Claims24
A work vehicle, comprising:
- a frame;
- a circle drive coupled to the frame;
- a moldboard coupled to the circle drive;
- and
- a planetary gear apparatus including an output shaft configured to mesh with the circle drive to rotate the circle drive relative to the frame.
2 more elements
A method, comprising:
- providing a first current to an electric motor to move a moldboard of a work vehicle, the electric motor coupled to the moldboard via a planetary gear apparatus;
- providing a second current to the electric motor to secure the moldboard in a first position;
- monitoring a first output torque of the electric motor;
- and
- based on the monitoring, applying a brake to the moldboard and reducing the current flow to the electric motor when the first output torque is greater than a predetermined value.
2 more elements
A method, comprising:
- receiving an input indicative of a circle rotate control being positioned in a non-neutral position;
- monitoring at least one of a pressure of a hydraulic motor, a torque on a moldboard, or a direction that the moldboard is moving, the hydraulic motor coupled to the moldboard via a planetary gear apparatus;
- and
- based on the monitoring, applying a brake to the moldboard when the least one of the pressure, the torque on the moldboard, or the direction that the moldboard is moving is different or greater than a particular value.
