Patent number: 11041530Abstract: A shaft bearing for mounting a shaft of a motor vehicle, having an inner sleeve, an outer body which surrounds the inner sleeve thereby forming a gap, and an elastomer body which connects the inner sleeve and the outer body elastically to one another. The inner sleeve may be embedded in the elastomer body and form a receiving opening for pressing in a bearing element. The inner sleeve may have at least one first deformation which is directed radially inwards in such a way that a shear gap is formed between the first deformation and the bearing element. An elastomer bead that may be formed when the bearing element is pressed in may be compressed within the shear gap.Type: GrantFiled: July 13, 2018Date of Patent: June 22, 2021Assignee: VIBRACOUSTIC GMBHInventor: Friedrich Back
