Abstract
The invention relates to a functional hydro-elastic element to be lodged in a hydro-elastic joint for damping load vibrations between two structural parts, in particular a wheel suspension and a vehicle body, the functional hydro-elastic element having a longitudinal axis and a circumferential direction around this longitudinal axis. The functional hydro-elastic element has at least one row of hydraulic chambers, extending circumferentially and comprising at least three hydraulic chambers and at least one throttling duct that enables a communication of liquid between each pair of respective circumferentially adjacent hydraulic chambers so that a variation of at least one working volume of the hydraulic chambers due to load vibrations can be balanced by enabling a flow of liquid into at least one of the other hydraulic chambers.
