Abstract
A flywheel assembly comprises a first flywheel connectable to an engine crankshaft, a second flywheel on which a clutch mountable, rotatably supported by the first flywheel, and a replaceable inter-flywheel drive-driven plates/damper unit. The unit is composed of a drive plate sandwich detachably connected to the first flywheel, a composite driven plate disengageably engaged with the second flywheel, and a viscous damper. The viscous damper connects the drive and driven plates, and the compound damper/drive-driven plates unit is replaceable as a whole.
Claims15
A flywheel assembly comprising:
- a first flywheel connectable to an input member;
- a second flywheel connectable to an output member, supported rotatably on said first flywheel;
- a unitary, removable damping unit located between said first and second flywheels;
- and
- a connection member for solely and detachably connecting said damping unit to said first flywheel, said connection member being capable of repeated use for said detachable connection,
- said damping unit comprising:
- a pair of ring-shaped drive plates, one of which being detachably connected to said first flywheel through said connection member;
- a ring-shaped driven plate interposed between said pair of drive plates, and being detachably connected to said second flywheel;
- a viscous damping fluid interjoining said drive plates and said driven plate;
- and
- a plurality of pins for connecting said pair of drive plates at a given spacing therebetween, whereby said drive plates, said driven plate and said viscous damping fluid are assembled as an integral unit;
- whereby said damping unit may be easily selectively removed and integrally replaced with another damping unit having the same or modified damping characteristics.
