Abstract

A hydramount, including a supporting bearing and a bearing member, which are supported on each other by a substantially frustoconical, first elastic spring element made of elastomeric material. The hydramount includes a working chamber and a compensating chamber, which are each filled with hydraulic fluid, are separated from each other by a partition, and are in fluid communication via a first damping opening. The supporting bearing is in the form of an internal, first supporting body, which is encircled by an external, second supporting body, at a radial distance. The first and the second supporting bodies are connected by the first elastic spring element and a second elastic spring element. The first elastic spring element and the second elastic spring element define at least two chambers filled with hydraulic fluid. The chambers are positioned transversely to the axis, substantially in diametric opposition to each other in the radial direction, and are in fluid communication via at least one second damping opening.
