Spring device for use in friction clutch in drive train of combustion engine-driven motor car, has actuator for opening clutch against lever spring force, and spring lug whose spring force acts parallel to spring force of another spring lug

摘要

The spring device has a lever spring (102) supported on sides of a housing and a pressing plate, where the lever spring has an annular disk-shaped region (104) extending radially inward from a spring lug (108) and radially outward from an attachment piece (116). The annular disk-shaped region exerts force on the pressing plate in a clutch closing direction, and an actuator opens a clutch against force of the lever spring. Spring force of another spring lug acts parallel to the spring force of the former spring lug.
