Abstract

A bearing bush for a vehicle is disclosed. The bearing bush includes an inner ring, an outer ring, and an elastomer element between the inner and outer rings. An actuator is configured to cause an application of a force on the elastomer element in a radial direction against at least one of the inner ring and outer ring to alter the rigidity of the bearing bushing. This provides a system for mechanically altering the rigidity of the bearing bush, making the bearing bush switchable between at least two rigidity states.
