<p>The invention relates to a device for active steering of a truck provided with a power steering arrangement (50), comprising a steering wheel gear (10) of 5 differential type for transmitting to an output shaft (34) both a steering wheel angle deflection from an input shaft and a steering angle deflection which is superimposed on the steering wheel angle deflection by a positioning means. According to the invention, the transmission of the steering wheel angle deflection in the steering wheel gear (1 0) is catered for by a gear step (a, b, c, d) 10 to gear down the steering wheel angle deflection to the output shaft (34), with a ratio such that the truck can be steered manually in the event of failure of the power steering (50).</p> |
