Hydraulically damping rubber bearing, consisting of an inner tube, an outer tube located concentrically or eccentrically in relation to the inner tube and at some distance from it, and a rubber part inserted between them in which there are at least two chambers which are filled with damping fluid and are hydraulically connected to one another, whereby in each of at least two chambers there are respective stop bodies, whereby the stop bodies are connected to one another by means of an element which has a hydraulic connection, the element thereby has a groove which is open toward the radial outside and is located on the inside of the outer tube so that the groove, together with the inside of the outer tube, forms the flow connection, whereby the element is realized in one piece, and whereby the element has an opening over its axial length, the clear width of which opening is larger than the diameter of the inner tube.

[ What is claimed is:] [1.] A hydraulically damping elastomeric bearing for use in a motor mount of a motor vehicle, comprising:an inner tube structure;said inner tube structure comprising an inner tube;said inner tube having a longitudinal axis and defining an axial direction along said longitudinal axis and defining a radial direction transverse to said axial direction;said inner tube having an outer diameter;an outer tube;said outer tube being disposed about said inner tube;said inner tube being displaceable in the radial direction with respect to said outer tube;an arrangement to separate said inner tube and said outer tube;said separating arrangement being disposed between said inner tube and said outer tube;said separating arrangement defining at least two chambers;hydraulic fluid being disposed in said at least two chambers;two stop bodies;one of said two stop bodies being disposed within one of said at least two chambers;the other of said two stop bodies being disposed within the other of said at least two chambers;a one-piece connecting element;said connecting element being disposed to connect said stop bodies to one another;said stop bodies and said connecting element together comprising a unitary one-piece structure;said connecting element comprising a flow channel to allow said hydraulic fluid to flow between said at least two chambers;said connecting element comprising an opening in the axial direction;said opening having a width defined substantially transverse to the axial direction;the outer diameter of said inner tube being less than the width of said opening in said connecting element;said inner tube structure comprising two portions;each of said two portions of said inner tube structure being disposed to make contact with its corresponding one of said two stop bodies;one of said two contact portions being disposed within one of said at least two chambers to correspond to its corresponding stop body disposed within its corresponding chamber;the other of said two contact portions being disposed within the other of said at least two chambers to correspond to its corresponding stop body disposed within its corresponding chamber;each of said two contact portions being disposed at least substantially adjacent to its corresponding stop body;each of said stop bodies being configured to stop movement in the radial direction of its corresponding contact portion upon its corresponding contact portion being displaced in the radial direction against its corresponding stop body; andeach of said two contact portions being disposed to permit said hydraulic fluid to flow between each contact portion and its corresponding stop body upon displacement of each contact portion away from its corresponding stop body.
