Abstract

A pressure plate subassembly for a motor vehicle friction clutch, which subassembly comprises an application plate or pressure plate which, when assembled in a motor vehicle friction clutch, is connected to a flywheel to rotate jointly around an axis and can be axially displaced with respect to the flywheel. The pressure plate has a friction surface which faces the flywheel, and at least one clearance sensor is provided on the pressure plate. The clearance sensor has an operation lever segment that cooperates with a wear adjustment device, and an axial stop segment which cooperates with the flywheel. The pressure plate subassembly comprises the displacement contrivances, which displacement contrivances prevent a displacement of the clearance sensor, of which there is at least one, with respect to the pressure plate prior to the assembly of the pressure plate subassembly to the flywheel. The clearance sensor, of which there is at least one, can be displaced in the axial direction with respect to the pressure plate and is held on the pressure plate in the axial direction by spring pre-stressing.
