Abstract

ABSTRACT

A hydraulically dampened rubber support includes a load bearing support, an annular spring element of elastic rubber material and a support base, which together enclose a working chamber and a compensation chamber.
These chambers are connected through a first damping passage. The working chamber, the compensation chamber and the damping passage are filled with liquid. The spring element has at least two spring sections in the shape of hollow cones arrange symmetrically to a plane which extends transversely to the axis of movement. The spring sections are secured with their adjacent ends to a rigid connecting element which defines a second damping passage.
Such a hydraulically dampened rubber support provides a good damping of vibrations of a supported load over a wider range of frequencies whilst ensuring a long spring travel.
