Power take-off clutch i.e. friction clutch, for drive train for driving agricultural attachment of tractor, is controlled by proportional valve to adjust pressure, where different rotational torques are transferred from clutch

The clutch is controlled by a proportional valve such that pressure (P-1) is adjustable at the clutch. Different rotational torques are transferred from the clutch based on pressure torque characteristics depending on the pressure, where the pressure amount is 10 Pascal (Pa). Slippage of the clutch...

Beschreibung
Zusammenfassung:	The clutch is controlled by a proportional valve such that pressure (P-1) is adjustable at the clutch. Different rotational torques are transferred from the clutch based on pressure torque characteristics depending on the pressure, where the pressure amount is 10 Pascal (Pa). Slippage of the clutch is detected by comparing the engine speed and the speed of the clutch, where warning is output to a driver of a tractor when the slippage of the clutch is detected. An independent claim is also included for a method for operating a power take-off clutch. Es wird eine Nebenabtrieb-Kupplung, insbesondere eine Nebenabtrieb-Kupplung eines Antriebsstrangs zum Antrieb landwirtschaftlicher Anbaugeräte vorgeschlagen, welche über ein Proportionalventil steuerbar ist, so dass an der Nebenabtrieb-Kupplung verschiedene Drücke einstellbar sind, wobei von der Nebenabtrieb-Kupplung anhand der Druck-Drehmoment-Kennlinie in Abhängigkeit vom Druck verschiedene Drehmomente übertragen werden können.
