Hydraulically damped body mount with bolt-through construction

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, said elastomeric bushing including a wall covering said gap;
• a first annular chamber and a second annular chamber defined between said elastomeric bushing and said outer metal, said first and second annular chamber being spaced from each other in said axial direction;
• a first passageway extending between said first and second annular chambers, said first passageway defined by and extending circumferentially around a radially outer surface of said elastomeric bushing;
• and
• a third chamber and a fourth fluid chamber defined between said elastomeric bushing and said outer metal, said third and fourth fluid chambers being spaced from each other in said diametric direction.

• and
• an elastomeric bushing disposed between said inner and outer metals;
• wherein:
• said elastomeric bushing defines a first annular fluid chamber, a second annular fluid chamber and a first fluid passageway connecting said first and second annular fluid chambers, movement of one of said inner and outer metals with respect to the other of said inner and outer metals in the axial direction being controlled by said first annular fluid chamber, said second annular fluid chamber and said first fluid passageway;
• said elastomeric bushing defines a third fluid chamber, a fourth fluid chamber and a second fluid passageway connecting said third and fourth fluid chambers, movement of one of said inner and outer metals with respect to the other of said inner and outer metals in the diametric direction being controlled by said third fluid chamber, said fourth fluid chamber and said second fluid passageway;
• said first annular fluid chamber, said second annular fluid chamber and said first fluid passageway being sealed from said third fluid chamber, said fourth fluid chamber and said second fluid passageway.
