Abstract
A clutch assembly for use with a vehicle's internal combustion engine, including a driving flywheel connected to an engine output, a driven flywheel rotatably mounted on the driving flywheel through a flanged bush, coil springs provided between the driving flywheel and the driven flywheel for imparting the rotational torque therebetween, and damping elements provided therebetween for absorbing vibration due to the fluctuating torque produced by the engine. The damping elements comprise a thrust washer, a friction plate and a dish spring which normally urges the driven flywheel toward the driving flywheel.
Claims5
A flywheel assembly for use with an internal combustion engine comprising,
- a driving flywheel drivingly connected to said internal combustion engine and provided with recess means, said driving flywheel having a boss portion;
- a flanged bush fitted on said boss portion of said driving flywheel;
- a driven flywheel rotatably mounted on, and co-axially positioned by, said flanged bush;
- a first plate confronting one side of said driving flywheel at the side of said engine;
- a second plate confronting the other side of said driving flywheel and interposed between said driving flywheel and said driven flywheel;
- each of said plates being fixed to said driven flywheel and provided with recess means in alignment with said recess means of said driving flywheel;
- resilient means disposed in said recess means of said driving flywheel and said first and second plates, thereby imparting a rotational torque from said driving flywheel to said driven flywheel;
- and
- damping elements provided between said first plate and said driving flywheel and having a thrust washer, a friction plate and a dish spring, thereby absorbing virbration due to the fluctuating torque produced by said engine.
