Hydraulic mounting for motor vehicle drives has flow channel inlet cross-sections controlled by closure caps with magnetorheological liquid to open and close channels according to the pressures in fluid chambers

摘要

The hydraulic bearing has a supporting body, attachment elements for connection to the parts to be mounted and two fluid chambers (8,9) with different stiffnesses separated by a rigid intermediate plate (7) with at least two cross-over channels (10), each closable by a mechanism (12), each mounted in an aperture in the intermediate plate and fixed by a connecting plate (24), that open and close the respective channels according to the pressures in the fluid chambers. The flow channel inlet cross-sections are controlled by closure caps with magnetorheological liquid.
