  • Publication number: 20230068612
    Abstract: A method of operating a machine with at least one hydraulically actuated friction clutch. The method includes selecting, via a mode selector, a starting point defining an initial setting. An endpoint defining a peak setting is selected via the mode selector. A control curve is employed based on at least the selecting of the starting point and the selecting of the endpoint. An inching pedal of the machine is positioned to between 0 percent depressed and 100 percent depressed. At least one control command is generated as a function of the employing of the control curve and the positioning of the inching pedal. At least one control valve of at least one hydraulically actuated friction clutch is operated according to the at least one control command.

  • Publication number: 20160041066
    Abstract: A method of monitoring a temperature of a clutch assembly of a machine is disclosed. The method includes determining a set of energy input parameters pertaining to the clutch assembly by one or more sensors. The method further includes determining a power output based on the lubricating oil temperature and the speed of the engine. The method includes determining a power input based on the pressure applied on the actuator and the clutch relative speed. The method further includes determining temperature at a surface of the reaction plate of the clutch assembly based on mathematical relationship between the power input and the power output. The method includes comparing the temperature at the surface of the reaction plate of the clutch assembly with a predefined temperature range. The method further includes creating an event, when the temperature at the surface of the reaction plate is greater than the predefined temperature range.
