PURPOSE: To provide an improved elastomeric bearing capable of damping the vibration transmitted effectively in the vertical direction and at least in one horizontal direction. CONSTITUTION: An elastomeric bearing is equipped with at least two mounting components 7 and 8, coupled together via one elastomer spring 6, at least one hydraulic shock absorbers being effective in the horizontal direction, and one hydraulic shock absorber being effective in the vertical direction. Each horizontally working shock absorber consists of at least two downward opening chambers, opposing mutually and formed by molding in the elastomer spring 6 and at least one passage 4 to put these chambers in mutual communication, wherein the under-part of the chamber 3a is bounded by a partition 5, under which second shock absorbers are provided in alignment in the direction of the Cz coordinate axis stretching vertically, where the chambers are positioned in front and in the rear about the direction of Cz coordinate axis and are in mutual communications via a passage 2. |
