HYDROELASTIC FUNCTIONAL ELEMENT AND HYDROELASTIC JOINT

摘要

The invention relates to a hydroelastic functional element (3) intended to be deposited into a hydroelastic joint (1) for damping load vibrations between two structural parts, in particular a vehicle body and wheel suspension, the hydroelastic functional element having a longitudinal axis (2) and a circumferential direction about said longitudinal axis, characterized by at least one row of hydraulic chambers (24, 26) extending circumferentially and including at least three hydraulic chambers and at least one throttling channel (40, 38), the at least one throttling channel of which enables liquid communication 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 liquid flow into at least one of the other hydraulic chambers.
