Abstract
A vibration damping assembly for a wheel or the like that undergoes rotation is achieved by providing an annular groove in a surface of the wheel coaxial with the wheel axis. An annular metal ring formed from a channel member generally U-shaped in cross-section is positioned with one of its legs within the annular groove substantially encased therein by a vibration damping material. The remainder of the channel member extends close to areas of the wheel that are adjacent to the groove, and vibration damping material is sandwiched between the wheel and the channel member. Vibration damping material subject to shear deformation during rotation of the wheel is used, along with vibration damping material subject to deformation in tension and compression.

In a vibration damping assembly for a member that undergoes rotation, and which includes an annular groove in an interior surface of said member which is coaxial with the axis of said member, the improvement comprising an annular metal ring formed from a channel member generally U-shaped in cross-section so as to include two legs and a base, one of the legs of said channel member being positioned within said groove and substantially encased therein by a vibration damping material, the base of said channel member extending adjacent to said interior surface of said rotatable member, the other leg of said channel member extending adjacent to an exterior surface of said rotatable member, and vibration damping material sandwiched between said base and other leg of said channel member and the adjacent surfaces of said rotatable member.
