Patent ID: 8534647

Claim:
An elastomeric bush bearing comprising: a metallic inner part ( 1 ), an elastomeric bearing element ( 2 ) encompassing the inner part ( 1 ) with a cage ( 3 ) vulcanized therein, an outer shell ( 4 ) accommodating both the inner part ( 1 ) and the bearing element ( 2 ), at least two chambers ( 5 ), for accommodating a damping medium located against the outer shell ( 4 ), being formed between an outer contour of the bearing element ( 2 ) and the outer shell ( 4 ), at least a pair of partitions ( 8 ) located between and spatially separating the at least two chambers ( 5 ) from one another, at least one damping medium channel ( 7 ) constructed either on or in the bearing element ( 2 ) and connecting the at least two chambers ( 5 ) with one another, and before the inner part ( 1 ), the bearing element ( 2 ) and the cage ( 3 ) are assembled with the outer shell ( 4 ), a force being directly applied to the cage ( 3 ) for reducing a dimension of the cage ( 3 ), but not the outer shell ( 4 ), so as to calibrate and prestress the elastomer of the bearing element ( 2 ), and following assembly of the inner part ( 1 ), the bearing element ( 2 ) and the cage ( 3 ) in the outer shell ( 4 ), the at least two chambers ( 5 ) being supplied with the damping medium to complete assembly of the elastomeric bush bearing such that the elastomer of the bearing element ( 2 ) is prestressed without pressurizing the damping medium.
