Abstract

The invention relates to a two-chamber bearing, in particular for motor vehicles, which has hydraulic damping, the liquid-filled chambers of which have rubber elastic peripheral walls and are connected to each other by a line which is provided in a rigid intermediate plate. According to the present invention, a so-called active bearing is provided which can be rapidly adapted to the operational conditions in each case by filling the chambers with an electroviscous liquid, the viscosity of which may be controlled by applying an electrical field in the area of the line which passes through the intermediate plate.
