ABSTRACT:
A disclosed clutch driven disc assembly includes a hub having an axis of rotation. A driven disc of the assembly is rotatably disposed over the hub and has a friction element disposed thereon. The disc also has a plurality of spring openings radially disposed between the hub and the friction element. A reinforcing plate having a plurality of spring openings aligned with the spring openings in the disc is fixed to each side of the disc. A cover plate having a plurality of spring openings is disposed over each of the reinforcing plates with the spring openings of all parts aligned. The cover plates are fixed to the hub for rotation therewith. A plurality of compression coil springs are disposed in the spring openings with the springs oriented such that relative rotation between the hub and the disc tends to compress the springs. An end cap is disposed at each end of the springs with a cap portion engaging the end of the spring and a pin portion extending from the cap portion disposed within coils of the spring, whereby the pin portions prevent the spring from buckling when it is compressed as a result of relative rotation between the hub and the disc.
