  • De-coupling mechanism for separating axial radial spring rates in an elastomeric mounting/isolation system
    Patent number: 6416030
    Abstract: An elastomeric mounting/isolation assembly (10) having several annular elastomeric elements (12, 32, 34), several rigid sleeves (14, 16, 40), and a fastener (42), in which the radial and axial spring rates are effectively de-coupled from each other such that changing one spring rate has substantially no, or little, effect on the other spring rate. The de-coupled spring rates can enable the assembly to better meet diverse considerations involving noise, vibration, and/or harshness, commonly known as NVH, on the one hand, and vehicle dynamics on the other hand.
