Abstract
This invention describes a control method for a hydraulic coupling system that includes pressurizing a fluid in an actuator coupled to a multi-disk clutch pack to engage the clutch pack, pumping the fluid through the clutch pack to cool the clutch pack, and controlling one or more valve actuators and one or more pump-motors with a controller. The control method may incorporate pulse width modulation of the actuators, such as the actuators for the pump-motor and valve.
Claims19
A method of controlling a hydraulic coupling system, comprising
- pressurizing a fluid in an actuator coupled to a multi-disk clutch pack to engage the clutch pack;
- pumping the fluid through the clutch pack to cool the clutch pack;
- and
- transmitting pulse-width modulated control commands from a controller to a set of valves and at least one pump to control the operation of the set of valves and the at least one pump.
