Abstract
A coupling assembly for agricultural implements has a friction coupling ( ), an electromagnet ( ) and control mechanism ( ). The friction coupling ( ) includes a friction assembly ( ) which is loaded by a pressure plate ( ). The pressure plate ( ) is loaded by pressure springs ( ). The pressure plate ( ) is adjustable by an actuating device ( ) which includes an electromagnet ( ) and an anchor plate ( ). The control mechanism ( ) includes a control member ( ) which, by changing the electric current, regulates the pressure force of the pressure plate ( ) during the coupling and/or uncoupling operation. The housing ( ) and the hub ( ) are associated with speed sensors ( ) which transmit a signal to the control mechanism ( ) to relieve the load on the friction assembly. Thus, this prevents the friction coupling ( ) from overheating.
