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.
Claims17
A bearing bushing for a motor vehicle, comprising:
- an inner ring;
- an outer ring;
- and
- an elastomer element disposed radially between the inner ring and the outer ring, wherein the bearing bushing can be switched between at least two rigidity states, and wherein the bearing bushing is configured to introduce a preloading force into the elastomer element;
- wherein the inner ring is radially elastic, and is disposed on a sleeve via at least two eccentric rings, wherein the at least two eccentric rings are rotatably disposed between the inner ring and the sleeve in order to introduce the preloading force into the elastomer element.
A bearing bushing for a vehicle, comprising:
- an inner ring;
- an outer ring;
- an elastomer element disposed radially between the inner ring and the outer ring;
- and
- an actuator 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 a rigidity of the bearing bushing;
- wherein the outer ring includes an inner surface defining a circumferential groove, wherein the bearing bushing includes a clamp located in the circumferential groove, and wherein the actuator is configured to force the clamp radially inward to increase the rigidity of the bearing bushing.
A bearing bushing for a motor vehicle, comprising:
- an inner ring;
- an outer ring;
- and
- an elastomer element disposed radially between the inner ring and the outer ring, wherein the bearing bushing can be switched between at least two rigidity states, and wherein the bearing bushing is configured to introduce a preloading force into the elastomer element;
- wherein the outer ring has numerous ramps on an inner circumferential surface, wherein the respective ramps interact radially with a respective tapered element, non-rotatably disposed on the elastomer element.
