Patent ID: 7416174

Claim:
A mount assembly for use with a vehicle having a frame and a vehicle body, said mount assembly comprising: a first carrier having a first flange and adapted to be coupled to the frame of the vehicle; a first insulator abutting said first flange of said first carrier for isolating movement of the frame relative to the vehicle body in a first direction, said first insulator formed of microcellular polyurethane having a non-linear modulus of elasticity; a second carrier having a second flange and adapted to be coupled to the frame of the vehicle; and a second insulator abutting said second flange of said second carrier for further isolating said movement of the frame relative to the vehicle body in said first direction; and an intermediate insulator coupling said first insulator to said second insulator and adapted to be mounted to the frame of the vehicle, said intermediate insulator formed of rubber having a substantially linear modulus of elasticity for isolating said movement of the frame relative to the vehicle body in said first direction and for isolating movement of the frame relative to the vehicle body in a second direction transverse to said first direction wherein said mount assembly can provide two different rates of elasticity during isolation of said movement in said first direction and can also isolate said movement of the frame relative to the vehicle body in said second direction transverse to said first direction.
