Patent number: 4616744Abstract: In a friction clutch unit the axial travel of the presser plate with respect to the clutch housing is axially limited. The presser plate is connected for common rotation with the clutch housing by a plurality of tangential leaf spring elements. These leaf spring elements allow axial travel of the presser plate with respect to the clutch housing, when the clutch housing is separated from the respective driving disc. A main spring is provided which is supported on the clutch housing and acts onto the presser plate. This main spring urges the presser plate away from the clutch housing. In order to restrict the travel of the presser plate under the action of the main spring stop elements are provided axially between the spring elements and the clutch housing and tangentially between the two ends of the respective leaf spring elements, namely nearer to that end of the respective leaf spring element which is fixed to the clutch housing.Type: GrantFiled: January 14, 1985Date of Patent: October 14, 1986Assignee: Fichtel & Sachs AGInventors: Dagwin Tomm, Dieter Kolb, Siegmund Gehrig, Alfred Meyer

Patent number: 4579210Abstract: 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.Type: GrantFiled: October 27, 1983Date of Patent: April 1, 1986Assignee: Fichtel & Sachs AGInventors: Alfred Meyer, Klaus Elsner
