Abstract

A rubber bearing with graduated damping characteristic has essentially a preferably cylindrical or approximately cylindrical inner part, a tubular outer sleeve arranged coaxially around the inner part as well as a pressure body with chambers for a damping agent. The pressure body is arranged in a fixed manner between the inner part and the outer sleeve. A rubber bearing which has a simple design and effectively damps forces introduced in different ranges of the characteristic due to its graduated damping characteristic is provided. The pressure body of the bearing is divided in the radial direction into a plurality of damping areas whose damping characteristics can be adjusted independently from one another by an intermediate sleeve arranged coaxially to the inner part and the outer sleeve.
