Abstract
In a clutch disc assembly, a hub disc extends outwardly from a hub and a cover disc is provided on each side of the hub disc. The cover discs are angularly movable about the axis of the hub between a neutral position and a pair of terminal positions each spaced on an opposite side of the neutral position. Groups of aligned windows are provided through the hub disc and the cover discs with the windows extending in the circumferential direction around the hub axis. A compression spring extends in the circumferential direction about the hub axis and is located within each group of aligned windows. The compression spring functions as a torsion spring operatively interconnecting the hub disc and the cover discs for resisting angular movement from the neutral to the terminal positions. A plurality of friction units are located between the hub disc and the cover discs and the friction units have different torque values. In a group of aligned windows, the circumferential extent of the window in the hub disc is greater than the circumferential extent of the windows in the cover discs. The compression spring within the group of aligned windows has a circumferential extent in the neutral posi…
