Abstract

An assembly for a motor-vehicle friction clutch, in which a pressure plate and a pressure spring are preassembled in a clutch casing. The pressure plate can move in the axial direction with respect to the clutch casing and is connected to the clutch casing in a rotationally fixed manner by means of leaf springs. A releasable transport securing device prevents the pressure plate from moving in the axial direction toward the open side of the clutch casing. The securing device acts between a stop area, which limits the axial displacement of the pressure plate or is formed by said pressure plate, and a corresponding opposing stop area on the clutch casing. The transport securing device is a locking element which is held between the stop area and the opposing stop area by frictional force or a form fit, and can be disengaged by spring force when the clutch is fitted or when the clutch is first actuated.
