Abstract
A clutch plate for use in friction clutches has a hub with a mounting flange which is flanked by two discs one of which carries the friction coatings and which are rotatable, within limits, with reference to the hub and/or vice versa. A first coil spring resists a first stage of rotation of the hub and/or discs from a neutral angular position, a second coil spring cooperates with a load friction generating unit to resist the first portion of a second stage of rotation of the discs and/or hub from the neutral position, and several coil springs cooperate with the friction generating unit to oppose the second portion of such second stage of rotation of the discs and/or hub from neutral position.
