Dynamic damper

A dynamic damper comprising:

• a resilient material having a central bore formed therethrough dimensioned to receive a vehicle axle, the central bore defining a first inner diameter;
• an annular mass surrounded and embedded in the resilient material, the annular mass defining a second inner diameter greater than the first inner diameter;
• and
• a metallic split ring embedded within the resilient material along a portion of the surface of the central bore with locking protrusions extending into the central bore, distal ends of the locking protrusions defining a third inner diameter smaller than the first inner diameter, the locking protrusions being dimensioned to extend into openings in the vehicle axle locking the metallic split ring, the resilient ring and the annular mass to the vehicle axle, the metallic split ring having a radially outer surface embedded within the resilient material, the radially outer surface of the metallic split ring having a plurality of radially outwardly extending projections embedded within the resilient material.

A dynamic damper comprising:

• a vehicle axle having a first end and a second end with a pair of openings defined on opposite sides of the vehicle axle between the first end and the second end;
• a resilient material having a central bore formed therethrough installed to the vehicle axle, the central bore defining a first inner diameter equal to an outer diameter of the vehicle axle;
• an annular mass surrounded and embedded in the resilient material, the annular mass defining a second inner diameter greater than the first inner diameter;
• and
• a metallic split ring embedded within the resilient material along a portion of the surface of the central bore with locking protrusions extending into the central bore, ends of the locking protrusions defining a third inner diameter smaller than the first inner diameter, the locking protrusions extending into the pair of openings in the vehicle axle locking the metallic split ring, the resilient material and the annular mass to the vehicle axle.
