Abstract

A bearing body (2) is divided in the radial direction (r) by at least one insert (6) arranged in the bearing body (2) parallel to the bearing axis (12) into at least two spring packets (7, 8) having an outer switching packet (8). Each of the working chambers (4, 4′) is divided into several chamber sections (91-9n) extending in the radial direction (r) and into at least one chamber section (10) extending in the axial direction (a) and connecting the chamber sections (91-9n) with one another. The elastomeric bearing body (2) is segmented in the switching packet (8) in the axial direction (a) by the chamber sections (91-9n) protruding into the elastomeric bearing body (2).
