Friction clutch for motor vehicles has membrane spring with angled section applying a load to flat contact pressure plate

摘要

The clutch has a plate-like diaphragm spring loading a contact pressure plate. The spring (10) has an angled section (13) directed towards the flat contact side (9) of the pressure plate (5), to apply a load to the plate. The section is at right angles to the spring plane, and consists of a single radial ring or several ring sections. Facing contact areas of pressure plate and/or angled section are formed to be low-wear and/or low-friction, e.g. these areas are hardened or have a low-wear and/or low-friction coating, or carry a component (15) with these characteristics. The contact pressure plate is of steel, or is a cast metal part.
