SLEEVE TYPE RUBBER SPRING HAVING HYDRAULIC BUFFER ACTION

摘要

PROBLEM TO BE SOLVED: To damp vehicle vibration generated axial and radial directions. SOLUTION: A sleeve type rubber spring having hydraulic buffer action comprises outside support sleeves 2 to surround an inside support sleeve 1 at intervals in a radial direction; an elastomer body 3 arranged between the two support sleeves 1 and 2 and forming at least one chamber 4 filled with a liquid force buffering medium; a cap 5 to form a second chamber 6 and close a rubber spring; and a channel plate 7 having a throttle passage to interconnect two chamber. Further, the outside support sleeve 2 has at least two different outside diameter regions, A small region on which a load is mainly radially applied is inserted in an automobile constituting member 8. At least two stopper cushions 9.1 and 9. 2 are arranged in a distribution manner in the inside support sleeve 1 region corresponding thereto throughout a wind direction. A large region is partitioned by a channel plate and has a chamber filled with a buffering medium.
