Abstract
Bearing bushes, for example, for a chassis of a motor vehicle are disclosed. A bearing bush may include a shaft, a hub, and an elastomer element which is arranged radially therebetween. The bearing bush may be configured to be switched between a first and second stiffness levels. The hub may have a main body and a plurality of radially adjustable plungers which are arranged in the main body. The plungers may be configured to engage the elastomer element and change the stiffness of the bearing bush from the first stiffness level to the second stiffness level. The elastomer element may have a plurality of radial elements arranged on the main body and configured to be compressed via a respective plunger in order to increase the stiffness of the bearing bush. An actuator including an electric motor may be configured to radially adjust the plungers in the main body.
