ABSTRACT:
A vibration damping insulator for supporting a structural member on a vehicle chassis. The insulator comprises a first tubular member connected to said structural member, a second tubular member disposed coaxially within the first tubular member and connected to the vehicle chassis, a first elastomeric body interconnecting the first and second tubular members and arranged to undergo shear when the tubular members are displace in one direction and compression when the tubular members are displaced in a second direction relative to each other, a stiffening plate disposed in the first elastomeric body between the first and second tubular members, a vibratable mass, and a second elastomeric body separate from the first elastomeric body and interconnecting the vibratable mass and one of the tubular members. The second elastomeric body and the vibratable mass define a dynamic damper having a resonance characteristic which suppresses transmission of vibration from the structural member to the chassis.
