Title: SWITCHABLE BEARING BUSHING FOR A MOTOR VEHICLE
Abstract:
The invention relates to a bearing bushing (1) for a motor vehicle, wherein the bearing bushing (1) is switchable between a first stiffness stage and a second stiffness stage. According to the invention, the bearing bush (1) comprises a first elastomer ring (3a) arranged rotationally fixed on an outer circumferential surface of an inner ring (2), and a second elastomer ring (3b) arranged rotationally fixed on an inner circumferential surface of an outer ring (4), wherein, radially between the two elastomer rings (3a, 3b), an intermediate ring (5) comes into contact in a rotationally fixed manner on the two elastomer rings (3a, 3b), wherein in addition, the first elastomer ring (3a) can be bypassed via the intermediate ring (5) and at least one blocking ring (6a) arranged on the end face on the bearing bush (1), in order to change the stiffness of the bearing bush (1).
