Title:
ハイドロリック減衰作用を有するブッシュベアリング
Document Type and Number:
Japanese Patent JP4718484
Kind Code:
B2
Abstract:
A hydraulically damping bush bearing ( 1 ) has an inner part ( 1 ) with a hole ( 3 ) extending along a longitudinal axis ( 4 ); an outer sleeve ( 9 ) surrounding the inner part ( 2 ); an elastomeric damping member ( 6 ) arranged between the inner part ( 2 ) and the outer sleeve ( 9 ); and at least two chamber pairs ( 21, 24 ) with at least two separate chambers ( 19, 20; 22, 23 ) each, which are filled with a hydraulic fluid. The two chambers ( 19, 20 ) of a first chamber pair ( 21 ) are arranged axially along the longitudinal axis ( 4 ) and the two chambers ( 22, 23 ) of a second chamber pair ( 24 ) are arranged radially in relation to the longitudinal axis ( 4 ) and are arranged in the axial direction of the longitudinal axis ( 4 ) between the two chambers ( 19, 20 ) of the first chamber pair ( 21 ); a channel carrier ( 13 ), which connects to one another the two chambers ( 19, 20; 22, 23 ) each of one of the chamber pairs ( 21, 24 ) via at least one damping channel ( 25, 26 ) each arranged in or at the channel carrier ( 13 ); and an outer bush ( 12 ), which surrounds the elastomeric damping member ( 6 ), the outer sleeve ( 9 ), the channel carrier ( 13 ) as well as the at least two chamber pairs ( 21, 24 ). The chambers ( 19, 20 ) of the first chamber pair ( 21 ) and the chambers ( 22, 23 ) of the second chamber pair ( 24 ) overlap in some areas at least an axial partial section (A, B) in relation to the longitudinal axis ( 4 ).
