Abstract: An upper mount assembly includes a pair of plates seating at least one Belleville spring. The plates are concentrically mounted about a hydraulic damper so that the Belleville spring is in series with a coil suspension spring. During use, deflection of the Belleville spring provides an additional degree of motion to reduce transmission of vibration to the vehicular body.
