ABSTRACT:
For emergency operation of an automatic friction clutch (3) of a truck which is operated during normal running by an electronic controller (9) via an electric motor driven actuator (11) and a hydraulic system (19, 21, 23), it is proposed that the clutch be controlled manually via a compressed air actuator (29), in particular via a compressed air servo actuator, by means of a changeover valve (39) which connects the compressed air actuator (29) alternately to a compressed air source (37) or via a flow throttle (41) to the atmosphere.
