Patent attributes
A mount assembly having a first carrier and a second carrier with each of the carriers being coupled to a frame of a vehicle. A first insulator abuts the first carrier and a second insulator abuts the second carrier for isolating movement of the frame relative to the vehicle body in a first direction. The first insulator is formed of microcellular polyurethane having a non-linear modulus of elasticity. An intermediate insulator is also mounted to the frame of the vehicle. The intermediate insulator is formed of rubber having a substantially linear modulus of elasticity. The intermediate insulator may include a structural insert encapsulated by the rubber. The intermediate insulator further isolates the movement of the frame relative to the vehicle body in the first direction to provide two different rates of elasticity. The intermediate insulator also isolates movement of the frame relative to the vehicle body in a second direction transverse to the first direction.
