Beschreibung
Zusammenfassung:	An arrangement for blocking the engagement of a clutch (5) of a motor vehicle comprises a lock actuator (9) which can be switched over to close a valve 30 to prevent damage to the engine (3) resulting from excessive speeds occurring in the event of an incorrect gear change to too low a gear. A control device (13) is connected to a gearbox input speed sensor (12) via an inhibiting or locking circuit (17) and the connection between the control device (13) and the lock actuator (9) is maintained irrespective of the positions of the gear change box. The inhibiting circuit (17) transmits an input signal for the control device (13) only above a limiting value. Either the control device (13) is influenced solely by the gear speed and the valve 30 is bypassed by a check valve (41) for disengagement of the clutch (5) - or the control device (13) brings the lock actuator (9) into the locking position only upon the appearance of two input signals, the second input signal of which is triggered if the clutch actuator (8) is brought into its release position. The clutch may automatically re-engage through a restriction when valve 30 reopens.
