Liquid-sealed body mount

A liquid-sealed body mount, comprising:

• an inner cylinder and an outer cylinder disposed in a concentric relation;
• a first rubber member and a second rubber member connected to and extending between both cylinders in axially spaced relation to each other to define a chamber therebetween;
• an insert cylinder fitted in said outer cylinder adjacent one end thereof, said first rubber member being bonded by vulcanization, at its radially outer and inner peripheral portions, to said insert cylinder and said inner cylinder adjacent said one end;
• a first sleeve fitted on said inner cylinder adjacent an other end thereof, said second rubber member being bonded by vulcanization, at its radially outer and inner peripheral portions, to said outer cylinder adjacent said other end and said first sleeve, respectively;
• an intermediate rubber plate means interposed between said first and second rubber members for partitioning said chamber into a first liquid chamber and a second liquid chamber, the former being defined between said intermediate rubber plate means and said first rubber member and the latter being defined between said intermediate rubber plate means and said second rubber member, said intermediate rubber plate means including an intermediate rubber plate, a second sleeve fitted in place on said inner cylinder midway between both ends and a ring element fitted in place in said outer cylinder midway between both ends, said intermediate rubber plate being bonded by vulcanization, at its inner and outer peripheral portions, to said second sleeve and said ring element, respectively, said second sleeve being held in place endways between said first rubber member and said first sleeve and said ring element being held in place endways between said second rubber member and said insert cylinder;
• means defining an orifice in said intermediate rubber plate means communicating with both of said first and second liquid chambers exclusively therethrough;
• a liquid filled in both of said first and second liquid chambers, said intermediate rubber plate means being configured so that, when assembled, it is held in place by being deformed in a shearing direction with its inner peripheral portion on an inner cylinder side and its outer peripheral portion on an outer cylinder side being axially offset, thus assuming a conical form whereas, when a prescribed load is imposed between said inner cylinder and said outer cylinder, said intermediate rubber plate means will retain its neutral and relaxed state and be nearly orthogonally related to both cylinders.
