Upper support for shock absorber in suspension system, having elastically supported resonance member.

摘要

An upper support for a suspension system, having an inner and an outer rigid member (10, 12), at least one generally annular elastic body (14, 16) interposed between the inner and outer rigid members for elastic connection therebetween, and which defines a generally annular fluid chamber (60) that is filled with a non-compressible fluid. The upper support also includes an annular resonance member (56) which is accommodated in the fluid chamber, and which is supported by one of the inner and outer rigid members so as to radially extend toward the other rigid member, so that the fluid chamber is substantially divided into two sections (58) located on axially opposite sides of the resonance member. The upper support further includes a support device (14, 16; 54, 55; 68, 70) for elastically supporting the resonance member with respect to the above-indicated one of the inner and outer rigid members, such that the resonance member can be axially displaced relative to the one rigid member due to elastic deformation of the support device.
