<p>Variable hydraulic power steering, comprising, mounted so as to pivot coaxially, a control shaft (1) which can be driven by the steering wheel, and a driven shaft (3) connected to a steering rack (7), elastic means (13) connecting the two shafts (1 and 3), a distributor comprising an inner element (2) integral with one of the shafts, and an outer element (4) integral with the other shaft and capable of controlling fluid circulation as a function of the relative angular position of the two elements (2 and 4), and an assisting actuator (10) which is connected to the distributor and capable of driving the steering rack (7). This steering comprises additional elastic means (22) between the control shaft (1) and the driven shaft (3), and means for modulating the rigidity of these additional elastic means. <IMAGE></p> |
