Abstract
A torsional vibration damper having two inertia members. A first inertia member is coupled to a hub by elastomer. A second inertia member is positioned within an annular cavity and is surrounded by a liquid of high viscosity. Under the influence of torsional vibrations relative movement arises between the hub and first inertia member, the hub and the second inertia member, and the first and second inertia members. The latter relative motion inhibits the attainment of resonance by either of the two inertia members.
Claims14
A torsional vibration damper including, an annular hub member, said hub adapted to be coupled to a rotary shaft subject to torsional vibrations, a first inertia member resiliently coupled by elastomer to said hub, a closed cavity adjacent to and positioned at the radially outermost portion of said hub, a second inertia member, said second inertia member positioned within said cavity and surrounded by a liquid of relatively high viscosity, a liquid shear coupling defined by said liquid between said first and second inertia members and between said second inertia member and said hub.
