Clutch Disc

Composition and Variations

The diagram on the left shows a typical car clutch disc with a two-stage torsion damper, integrated idle damper and a variable friction control assembly.

Its components are: The clutch facings (1), which are riveted to the spring segments (3) with the facing rivets (2). These spring segments are fastened to the retainer plate (17) with rivets. The retainer plate (17) is aligned to rotate on the hub by means of the pivot bushing (22).
The torsion damper is composed of the idle damper with springs (10 and 11), the main damper with springs (12 and 13) and the friction control assembly friction washer (8), and friction control plate (20), spring washer (7), and support washer (9).
