Abstract
A clutch plate with a first and a main damping unit wherein only the first damping unit is operative during a first stage of angular displacement of the input and output components of the clutch plate and only the main damping unit is operative during the remaining stage of such angular displacement. A load friction generating device is installed between the input and output elements of the first damping unit in such a way that it is effective only during an advanced part of the first stage of angular displacement and then cooperates with one or more compressible coil springs of the first damping unit. The load friction generating device is effective when the engine of a vehicle wherein the friction clutch between the crankshaft and the change-speed transmission embodies the clutch plate is idling and/or while the vehicle is set in motion.
