Title:
FRICTION CLUTCH UNIT
Document Type and Number:
Japanese Patent JPS56160427
Kind Code:
A
Abstract:
A friction clutch assembly wherein the first of two coaxial friction clutches has a friction disc driven by the crankshaft of an internal combustion engine and driving two pressure plates forming part of a flywheel which includes a second friction clutch whose friction disc drives the input shaft of the change-speed transmission in an automotive vehicle. The friction disc of the second clutch is flanked by the pressure plates of the respective clutch, and each clutch has an axially movable pressure plate and an axially fixed pressure plate. The axially fixed pressure plate of one clutch can be integral with the axially fixed pressure plate of the other clutch. The clutches can be engaged or disengaged by a common actuating system having a common dished spring the radially outermost region of which biases the axially movable pressure plate of one of the clutches. A second region which is located radially inwardly of the outermost region of the dished spring biases the axially movable pressure plate of the other clutch in engaged condition of the clutches. A second dished spring can be used to bias the axially movable pressure plate of the one clutch in engaged condition of the one clutch. The second spring can exert force by way of the common dished spring. The radially innermost portion of the common dished spring is movable axially in a given direction to engage the clutches and counter to such direction to disengage the clutches. The second clutch is disengaged ahead of the first clutch, and the first clutch is engaged ahead of the second clutch.
