HYDRAULIC DAMPING TYPE RUBBER SUPPORTER

PROBLEM TO BE SOLVED: To damp lower frequency vibration in the axial direction, and reduce dynamically resilience in a higher frequency region to isolate higher frequency vibration. SOLUTION: A hydraulically damping rubber bearing comprises an inner supporting body 1 surrounded with radial clearance by an outer supporting body 2, the inner and the outer supporting bodies 1, 2 are joined together by a resilient elastomeric element 3, a working chamber 5 is formed that is separated from a compensating chamber 8 by a separating wall having a duct-shaped opening 7, is connected to the compensating chamber such that it is in fluid communication with it, and is filled with damping fluid 4, and the compensating chamber 8 is sealed essentially at null pressure on the side facing away from the separating wall 6 by a first membrane 9. The separating wall 6 is formed as an integral pipe 10 with window having a window 11, and has the opening 7 which surrounds the inner supporting body 1 with radial clearance, and an annular gap 12 is formed as a damping duct 13. The window 11 of the pipe 10 is filled in by a second membrane 24 made of elastomeric material to isolate higher frequency vibration.
