An automotive starting clutch having an input, including a pressure plate and a back plate, and an output disk releasably clamped by the pressure plate for rotation with the input. A control diaphragm provides a control force to vary the clamping force of the pressure plate between zero and maximum values and includes radial fingers movable axially to vary the control force. The control force of the diaphragm is counterbalanced by a Belleville spring in proportion with actuating travel of the radial fingers. By adding a single Belleville spring to an otherwise conventional clutch, it is possible to reduce considerably the control force of a conventional starting friction clutch, allowing the use of inexpensive electronically controlled actuators. |
