Abstract:
An articulated work machine is steered via left and right hydraulic cylinders that swivel a front portion of a work machine relative to a back portion about a vertical articulation axis. When a low force turn is being performed, high pressure is supplied to only one of the left and right hydraulic cylinders. When a high force turn is performed, high pressure is supplied to one of the left and right hydraulic cylinders, and pressurized hydraulic fluid is also supplied to the other of the left and right hydraulic cylinders in proportion to the torque required for the turn. This strategy allows for excess pressurized fluid, which is not used for the steering purpose, to be utilized by hydraulic implements of the work machine to increase performance capabilities while the machine is being steered in low force mode under light steering load.
