ABSTRACT:
An active two-chamber engine mount with hydraulic damping includes rubber-elastic peripheral walls, a rigid intermediate plate disposed within the peripheral walls defining two chambers interconnected by a channel formed in the intermediate plate, one of the chambers being an engine-side chamber bordered by one of the peripheral walls acting as a support spring exercising a spring deflection, mutually parallel and overlapping electrodes defining the channel, an electro-viscous fluid filling the chambers, a device for applying an electric field to the electrodes controlling viscosity of the fluid, and a device for varying the length of the channel and the degree of overlap of the electrodes in dependence on the spring deflection of the support spring.
