Abstract:
A hydraulic sleeve, comprising:an inner supporting body;an outer supporting body surrounding the inner supporting body, wherein a radial clearance is maintained between the inner supporting body and the outer supporting body;a first liquid-filled working chamber;a second liquid-filled working chamber;a damping channel, wherein the first and second liquid-filled working chambers are in fluidic communication with one another through the damping channel;an elastic spring element arranged in a gap formed by the radial clearance, wherein the elastic spring element is formed from an elastomeric material, and wherein the elastic spring element has an essentially triangular cross-section and bounds the first working chamber; andat least one separate insertion part having an essentially .OMEGA.-shaped cross-section, wherein the insertion part is arranged within the first working chamber, wherein the insertion part divides the first working chamber into a plurality of sectional chambers that are in fluidic communication with one another through a plurality of throttle orifices bounded by the elastic spring element and by the insertion part, wherein the damping characteristics of the hydraulic sleeve are determined by selection of the geometry of the insertion part, and wherein the insertion part and the elastic spring element have facing sides, at least one of which sides includes surface profiling.
