Abstract
The rolling bearing with rotating electrical contacts comprises inner (7, 8) and outer (2) races gripping around the rolling elements (5, 6) and is equipped with means permitting the passage of an electrical current between two mechanical components, of which one is rotationally moveable in relation to the other. For this purpose at least one conductive cartridge (21) of generally annular form is mounted substantially in a frontal radial plane of the bearing, the said cartridge comprising two conductive armatures (22, 23), one being able to rotate in relation to the other, each armature being integral with one of the races of the rolling mechanism and at least one conductive element (29) pressed against one of the armatures (22) by at least one conductive elastic element (27) in contact with the other armature (23).
