Abstract
The disclosure relates to bearing bushes for a motor vehicle, in which the bearing bushing may be switchable between a first and a second stiffness stage.The bearing bushing may include a first elastomer ring, which is arranged at least indirectly on an outer circumferential surface of a bolt, and a second elastomer ring, which is arranged radially between a first and second sleeve. The second sleeve may be arranged radially between the first and the second elastomer rings. In order to change the stiffness stage of the bearing bushing, the two sleeves may be connectable to one another by at least one ring which comes into contact with said sleeves at an end side.
