ABSTRACT:
A clutch driven disc assembly includes an inner hub, an outer hub, an annular predamper driving element, an plurality of predamper springs, a plurality of spring caps, an annular spring plate, an annular disc assembly and a plurality of drive springs. The annular predamper driving element is rotatably fixed to the outer hub and has a planar base portion. The annular predamping driving element also has a plurality of axially extending spring retention arms and a plurality of spring engagement driving portions. The spring engagement driving portions are disposed radially inwardly of the spring retention arms. The spring retention arms define a plurality of first spring gaps in radial alignment with the spring retention arms. The annular predamper driven element is rotatably fixed to the inner hub and has an annular shoulder. The annular predamper driven element also has a plurality of axially extending spring engagement driven portions defining a plurality of second spring gaps. The second spring gaps are in radial alignment with the first spring gaps in a neutral condition. The predamper springs are disposed in the first and second spring gaps. The predamper springs are compressed with relative rotation between the predamper driving element and the predamper driven element. The annular spring plate is rotatably fixed to the outer hub. The annular disc assembly has a friction element fixed thereto. The disc assembly is mounted for relative rotation to the spring plate by a predetermined amount. The drive springs are operably disposed between the spring plate and the disc assembly.
