Abstract

See full text

A bearing bushing for a motor vehicle includes a sleeve, a bolt arranged inside the sleeve, and at least one elastomer element arranged radially between the sleeve and the bolt for supporting the bolt in the sleeve in a damping manner. The bolt has a ball element axially between two distal ends, wherein the ball element interacts with at least two movable ball socket elements in order to change the stiffness of the bearing bushing. This allows the bearing bushing can be switched between at least two stiffness levels.
