Tubular rubber spring with two supports - has rubber piece containing two fluid-filled compartments, with hole and stop pad containing release pocket

摘要

The tubular rubber spring comprises two mutually encircling supports (1,2) supported on each other by means of a rubber piece (3) containing two fluid-filled m compartments (5,6) joined by a damping-hole (4). At least one support (1) has a stop-pad (8) protruding into at least one compartment (5,6). The stop-pad (8) has an elastically deformable side. The stop-pad (8) contains at least one air-filled release-pocket (10) extending parallel to the side (9) which is in the form of a membrane in the part between the release pocket (10) and the compartments (5,6). The side of the stop-pad (8) not facing the release pocket (10) is partly reinforced by a rigid insert (11). USE/ADVANTAGE - The tubular rubber spring gives better insulation against high-frequency oscillations.
