Abstract

A hydraulically damping bearing which includes an inner bushing arranged in an outer bushing and an elastic element inserted therebetween. Chambers are provided within the elastic element which are filled with a damping medium and are connected with each other hydraulically by way of throttling channels extending in the area of the outer bushing. The throttling channels terminate in the chambers which, like the throttling channels, are sealed off against the outside. The bearing consists of two bearing halves adapted to be axially inserted into one another which include elastic bellows halves connected with the outer and inner bushing. The bellows halves include mutually opposite annular beads projecting into the interior of the chamber, between which is arranged an enclosed overflow channel.
