Abstract
A steering mechanism with variable gear reduction controlled by the speed of the vehicle of the type is disclosed which includes an electric motor for driving an element for adjusting the gear reduction ratio and whose power supply is controlled by the speed of the vehicle, characterized by the fact that the steering column includes an input shaft (1) and output shaft (2) to which are rigidly connected input pinions (4) and output pinions (5) meshed with planet pinions (6, 8-7, 9) of a planet carrier (10) which extends axially by a hub (11) placed concentrically to one of the shafts (1, 2) on which is mounted an element (12) for driving and regulating the gear reduction ratio actuated by a variable speed electric motor (13).
