Abstract: A triggering arrangement for a friction clutch includes at least one triggering element arrangeable on a clutch housing and is designed to interact with a pick-up arrangement to generate information relating to the rotary movement of the clutch housing about an axis of rotation. The at least one triggering element is of separate design from the clutch housing and is permanently connected or connectable thereto.

Abstract: A housing arrangement for a friction clutch including a ring-like housing wall region which has on its radially inward-facing inside a toothing formation for the rotary coupling of at least one friction member, the housing arrangement further including an annular disk-shaped housing bottom region integral with the housing wall region.

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.
