Patent attributes
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).
