PURPOSE: To provide a hydraulically suppressing type rubber bushing that provides a wide damping range through the demarcation of axial channels by metal-reinforced webs on its resilient rubber element that form radial walls and through the connection of annular channels by the connection of these axial channels parallel to the longitudinal axis of the resilient element. CONSTITUTION: Annular channels 6 and 7 are interconnected for fluid conduction therebetween by axial channels 9 parallel to the longitudinal axis of a resilient element 1 or rubber. The axial channels 9 diverge from axial to radial and open into the respective annular channels 6 and 7 at the respective ends. The axial channels 9 are demarcated by metal-reinforced webs 4 and 5 made on the resilient rubber element 1 as radial partition walls. Those two annular channels 6 and 7, which extend around the respective ends of the resilient element 1, are thus connected in series for fluid conduction via the axial channels 9 to offer a relatively long total channel length that establishes high-level damping of lower frequencies due to an increased buffer quantity. |
