Abstract:

A bushing is disclosed with a sleeve. The sleeve member has an inner surface and a cavity. A core member is disposed in the cavity. A pair of elastomeric members are disposed in the cavity. One of the pair of elastomeric members is adjacent to the core. The other of the pair of elastomeric members is adjacent to the inner surface. The one of the pair of elastomeric members has a modulus that is greater than the other of the pair of elastomeric members so that one of said pair of elastomeric members absorbs low frequency vibration and the other of the pair of elastomeric members absorbs high frequency vibration.
