.AN AUTOMATIC DISENGAGING/ENGAGING METHOD OF A CLUTCH DEPENDENT POWER TAKE-OFF

摘要

An automatic disengaging method for a master clutch dependent power take-off (PTO) (8) arranged in a vehicle for preventing undesired movement or actions of the implements associated with the PTO and undesired wear of a clutch collar (release bearing). The PTO (8) is driven by an engine via a master clutch (2) between a crankshaft (4) of the engine (1) and an input shaft (5) in a gearbox (3). The gear box (3) further comprises an output shaft (13) which is powered by the input shaft (5), optionally via an intermediate shaft (7). A power take-off (8) is connected to the input shaft (5) or, optionally, to the intermediate shaft (7). The system further comprises a control unit (10) connected to the master clutch (2) and the gear box (3). When the control unit (10) registers that the master clutch (2) is disengaged, a gear is engaged in the gearbox (3) and certain conditions are fulfilled (e.g. a parking brake has been actuated for a certain time), the control unit (10) performs the operations of putting the gearbox in a neutral position, disable the power take-off (8), if the power take-off (8) is enabled, and engage the master clutch.
