Vibration isolator encapsulated with fluid

Abstract

Abstract PURPOSE:To increase anisotropy of a vibration isolator encapsulated with fluid for car by forming at least four fluid chambers in resilient rubber placed between inner and outer tubes then classifying into more than two sets and communicating between respective sets. CONSTITUTION:Vibration isolator A encapsulated with fluid to be placed between chassis 12 and rear suspension member 1 is provided with inner tube 11 to be secured through bolts 13 to the chassis 12 and outer tube 15 to be secured through welding to a member 1. A flow path forming member 17 is pressure-inserted into the inner tube 11 then a resilient rubber body 16 is vulcanization adhered to said inner tube 11 and flow path forming member 17 while the outer tube 15 is fitted through seal rubber 18 over said resilient body 16. Four fluid chambers 19 are defined in said resilient member 16 and communicated through radial flow path 20 formed in the flow path forming member 17 to an annular path 20e to be partitioned into two chambers by partitioning members 21, 22 in the flow path forming member 17.
