The invention relates to a bearing device (80a, 80b) for a twist beam axle. The bearing device (80a, 80b) comprises an outer supporting element (81a, 81b) and an inner supporting element (82a, 82b), wherein the inner supporting element (82a, 82b) is at least partially arranged in the outer supporting element (81a, 81b). A supporting body containing magnetorheology is arranged between the outer supporting element (81a, 81b) and the inner supporting element (82a, 82b). The inner supporting element (82a, 82b) is annularly surrounded by the supporting body (90a, 90b), wherein the rigidity of the supporting body (90a, 90b) can be changed under the condition of applying magnetic field. According to the invention, the supporting body (90a, 90b) is devided into a first supporting area (91a, 91b) and a second supporting area (92a, 92b), and the supporting areas is in annular shape. The supporting areas (91a, 91b, 92a, 92b) is arranged between the outer supporting element (81a, 81b) and the inner supporting element (82a, 82b) as follow, that is, the inner supporting element (82a, 82b) and/or the outer supporting element (81a, 81b) can support at the first supporting area (91a, 91b) or a second supporting area (92a, 92b) along the opposite direction (x2, x3) to each other. The rigidity of the first supporting area (91a, 91b) and the rigidity of the second supporting area (92a, 92b) can be individually changed. Besides, the invention relates to a twist beam axle comprising the above bearing device and a corresponding vehicle.
