Abstract
A friction clutch system mechanically couples a power source to a driven system of a vehicle while reducing the rotational inertia of the clutch system and yet still providing torsional damping within the system. In one embodiment, the friction clutch system includes a first friction disc assembly directly engaged with a second friction disc assembly. The first disc assembly may include protuberances that extend axially from a hub assembly, which in turn may include damping springs and an internal splined region for coupling to a splined, driven shaft. The second friction disc assembly includes openings, which may take the form of radial slots, configured to engageably receive the protuberances. The first disc assembly may be positioned adjacent to a pressure plate assembly or a flywheel. A floater plate may be located between the first and second friction disc assemblies.
