A reduced noise decoupler has a perimeter with a wavy form. This provides a significant reduction in the initial contact noise. Hydraulic pressure deforms the wavy edges, pressing the wavy edge flat and creating the necessary seal. The edge geometry is created such that pressure will flatten the decoupler perimeter without creasing, ensuring a proper seal without losses. This is achieved by drawing the wavy detail from the perimeter to an interior of the decoupler body in alternating fashion to create a pattern of peaks and troughs bounded by thicker sections, allowing the edges to easily deform without creasing.

A vibration isolator assembly, such as an isolator bushing or cradle mount, includes a housing and an isolator connected to the housing. A shaft assembly includes first and second mating components, the first component being connected to the elastomer and having a cavity of a first dimension for receiving the second component having a different, second dimension therein. The differing dimensions alters the stress characteristics of the vibration isolator assembly. According to a preferred method of altering stress characteristics of a vibration isolator assembly, the method includes the steps of forming a cavity in the shaft and varying a dimension of the shaft to alter the spring rate characteristics. In the preferred arrangement, the shaft assembly includes a split, first component and a second component is inserted between the split portions to relieve tensile stress in the isolator and, if desired, to impart a compressive stress in the isolator.

In the preferred arrangement, the shaft assembly includes a first component comprising first and second portions, a thin layer of elastomer interposed between the first and second components and a second component which is inserted between the portions to relieve tensile stress in the isolator and, if desired, to impart a compressive stress in the isolator. The thin layer of elastomer permits the first components to be made more economically. The first component of the shaft assembly is made at a lower dimensional tolerance and subsequently produced to a higher dimensional tolerance by molding the thin layer of elastomer to a precision tolerance.

An adapter plate for pivotally securing an isolating mount to a drive train component is provided. The adapter plate includes a body portion which can be secured to the drive train. The adapter plate also includes a pivot support formed on the body portion. The pivot support has a pivot member for pivotally securing a first end of the isolating mount. The adapter plate also includes a securing member formed on the body portion. The securing member has an aperture for aligning with a corresponding aperture at a second end of the isolating mount. The isolating mount can pivot about the pivot support during installation of the drive train component within a vehicle, and the isolating mount can be secured to the securing member to prevent pivotal movement after installation of the drive train component within the vehicle.
