US 2006/0220448 A1 · Chassis bearing

Abstract

The invention relates to a chassis bearing (1), in particular for the rear axle of a motor vehicle. The bearing includes an outer bearing sleeve (2), an inner bearing sleeve (3), an elastomer body (4) that is situated between the outer and inner bearing sleeves and two chambers (5, 6), which are located between the outer and inner bearing sleeves and are delimited at least partially by the elastomer body. The chambers are separated from one another and are positioned symmetrically on either side of the longitudinal axis (7) of the inner bearing sleeve. Each chamber has a stop (8, 9), which is located on a common transverse axis (10) of the inner bearing sleeve and is positioned at a distance from a corresponding counterstop surface (11, 12) inside the chamber. According to the invention, the stops are configured so that they can be displaced and subjected to a pressure in such a way that they are displaced along the common transverse axis, fixing the inner bearing sleeve in relation to the outer bearing sleeve during any vibrations or oscillations. The pressure required to fix the stops is only completely built up when both stops rest against their counterstop surfaces.

A chassis bearing which can be subjected to an oscillating state comprising:

an outer bearing sleeve;
an inner bearing sleeve defining a longitudinal axis and a transverse axis extending transversely to said longitudinal axis;
an elastomeric body arranged between said first and second sleeves;
first and second chambers arranged between said outer and inner bearing sleeves so as to be at least partially delimited by said elastomeric body;
said first and second chambers being separated from each other and being disposed symmetrically on respective sides of said longitudinal axis;
first and second stops displaceably mounted on said transverse axis in corresponding ones of said first and second chambers;
first and second counter stop surfaces formed in corresponding ones of said first and second chambers so as to lie opposite corresponding ones of said first and second stops;
pressure means for applying pressure to said first and second stops so as to permit said first and second stops to be displaced along said transverse axis for fixing said inner bearing sleeve relative to said outer bearing sleeve during said oscillating state;
and,
ancillary means for permitting said pressure to be fully built up to a required pressure for effecting said fixing only when both of said stops lie in contact engagement with corresponding ones of said counter stop surfaces.
