Abstract
A mount has an inner metal and an outer metal with an elastomeric bushing disposed between them. The elastomeric bushing includes a first pair of interconnected passages to control the damping rate during axial motion and a second, separate pair of interconnected passages to control the damping rate during motion orthogonal to the axial direction.
Claims16
A mount comprising:
- an inner metal;
- a first outer metal disposed around said inner metal to form a first gap between said inner metal and said first outer metal;
- a first elastomeric bushing disposed within said first gap;
- a first annular chamber defined between said first elastomeric bushing and said first outer metal;
- a second annular chamber defined between said first elastomeric bushing and said first outer metal;
- a first passageway in communication with said first and second annular chambers, wherein:
- an outside diameter of said first annular chamber is smaller than an inside diameter of said second annular chamber.

A mount comprising:
- a cylindrical inner metal defining a central axis extending in an axial direction and a diametric direction generally perpendicular to said axial direction;
- an outer metal disposed around said inner metal to form a gap between said inner and outer metals;
- an elastomeric bushing disposed within said gap between said inner and outer metals;
- a first annular chamber and a second annular chamber defined between said elastomeric bushing and said outer metal, said first and second annular chambers being spaced from each other in said axial direction;
- a passageway extending between said first and second annular chambers, said passageway defined by and extending circumferentially around a radially outer surface of said outer metal;
- and
- a single piece internal tube disposed between said inner metal and said outer metal;
- wherein
- said first annular chamber is entirely disposed between said internal tube and said inner metal and said second annular chamber is entirely disposed radially outward from said internal tube.
