Title:
METHOD FOR OPERATING A DRIVE TRAIN HAVING A HYDRODYNAMIC CLUTCH
Document Type and Number:
WIPO Patent Application WO/2015/043841
Kind Code:
A3
Abstract:
The invention relates to a method for operating a drive train, comprising: a primary drive machine; a working machine driven by the primary drive machine; a hydrodynamic clutch between the drive machine and the working machine; and a temperature detection device for detecting the temperature in the hydrodynamic clutch. At least in the case of a change in the load state and/or operating state of the drive train, the temperature of the hydrodynamic clutch is detected at the time of the change. An expected temperature progression is calculated on the basis of the detected temperature and the new load state and/or the new operating state of the drive train. A warning and/or a stop signal for the primary drive machine is output if the temperature of the calculated temperature progression exceeds a specified maximum temperature within the expected duration of the new load state and/or of the new operating state.
