Abstract
Official abstract text for this publication.
The present disclosure provides a control system of a powered machine. The control system includes a hydraulic motor configured to drive a track system of the machine. The motor is operable with a variable displacement. A control valve is fluidly coupled to the motor. In addition, the control system includes a controller and an electro-hydraulic valve disposed in electrical communication with the controller and fluid communication with the control valve. The electro-hydraulic valve receives a signal from the controller, and based on the signal, the electro-hydraulic valve hydraulically varies the start of control pressure of the motor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control system of a powered machine, the machine having an engine for producing power and a track system for moving along a surface, comprising: a hydraulic pump adapted to provide fluid pressure to the control system; a hydraulic motor configured to drive the track system, the motor being operable with a variable displacement between a minimum displacement and a maximum displacement; a control valve fluidly coupled to the motor along a pressure…
