Hydraulic vibration isolating support for machinery or road vehicle suspension has fluid filled chambers in elastomeric bush joining inner and outer bushes

摘要

Each support (7) has a rigid metallic internal bush (9). An elastomeric bush (10) is bonded to the internal bush and has two crescent-shaped internal chambers (A,B) which are filled with fluid. The chambers are bounded on the outside by a metal ring (26) forming part of the outer bush and there are stiffening pieces in the portion of the elastomeric bush separating the two chambers. A flanged collar reinforces the top part of the elastomeric bush and is made in one piece with the stiffening pieces and a bottom piece (16).
