ABSTRACT:
The pressure plate unit for a motor vehicle friction clutch comprises a clutch housing (1a), a presser plate (3a) arranged in the clutch housing (1a) and guided non-rotatably but axially displaceably on the clutch housing (1a) and a clutch spring (13a) of substantially annular washer form arranged limitedly radially displaceably in the clutch housing (1a). The clutch spring is supported in the region of its external circumference axially on the clutch housing (1a) and on a diameter smaller than the diameter of the external circumference axially on the presser plate (3a). At least one radially resilient spring element is braced in between the clutch housing (1a) and the clutch spring (13a). The spring element holds the diaphragm spring in its original position in which the pressure plate unit was balanced in assembly, even during operation. The spring element can for example be a radially resilient spring sleeve or a U-shaped leaf spring which rests with one leg on the clutch housing and with the other leg on the diaphragm spring. Leaf springs which are secured with one end to the clutch housing or the diaphragm spring and are supported with the other end on the other component in each case are also suitable.
