Abstract
The sleeve rubber spring consists of an inner mounting sleeve (1), an outer mounting sleeve (2) surrounding the inner mounting sleeve at a radially spaced location, and a rubber body (3) arranged rigidly adhering between the two mounting sleeves. The rubber body forms at least two chambers (5, 6) are formed, which are filled with damping medium and permanently communicate with each other. An elastically deformable body forms a protective tube (4), into which the inner and outer mounting sleeves (2) are sealingly inserted. An overflow channel (8) with a shut-off device, which opens automatically at a predetermined pressure differential in the two chambers (5, 6) by radial deformation of the protective tube (4), is provided between the chambers (5, 6).
