Abstract: A bearing assembly (100) for supporting a steering shaft within a steering column tube including an outer bearing ring (120) defining an outer raceway (122), an inner bearing ring (130) defining an inner raceway (132), a plurality of roller elements (154) disposed between the inner raceway and the outer raceway, a support cone (160) defining an inner face and an outer surface, the support cone being disposed radially inwardly of, and in contact with, the inner bearing ring, and a biasing element (180) disposed adjacent the inner surface of the support cone. The biasing element exerts force radially-outwardly against the inner surface of the support cone.

Abstract: The present invention relates to a speed reducer comprising a shaft (11) extending along a longitudinal axis, two rolling bearings (16, 17) arranged around the shaft (11), the two rolling bearings (16, 17) each comprising a radially outer ring (19), a radially inner ring (18) and rolling elements (20) arranged between the radially outer and inner rings (19, 18), characterized in that it comprises a preload system positioned in the space between the two rolling bearings (16, 17), this preload system comprising: - two spacer elements (40) each one resting against one of the rings (18; 19) of the rolling bearings (16, 17), - at least one elastically deformable element (41) interposed between the two spacing elements (40), and configured to be able to occupy a preloaded first state and an least partially relaxed second state, the preload system being arranged in such a way that the transition of the said at least one elastically deformable element (41) from the first state to the second state causes a unidirectional rotational movement of each spacer element (40) with respect to the other so as to use a wedge effect to generate preload in the rolling bearings (16, 17).
