Abstract

An actuating installation for a friction clutch arranged in the drive line between a drive unit and a transmission. The installation having an actuating arrangement for the actuation of the friction clutch and a clutch-pedal arrangement, which is connected to the actuating arrangement and has a clutch pedal, which, in a first operating state, is actuable according to a force-travel characteristic of a first type. The actuating installation has a signaling and/or protection device, which is in operative connection with or is operatively integrated in the clutch-pedal arrangement, so that, after the response of the signaling and/or protection device to a second operating state, the clutch pedal can be actuated only according to a force/travel characteristic of a second type, which differs significantly from the force/travel characteristic of the first type in order thus to indicate the second operating state.
