摘要

A of hybrid engine driven steering assistance system for a commercial vehicle can comprise a mdps unit (10), so as to enable a engine (tm) in a function of a driver torque (td) to generate; a ehps unit (20), so as to enable a hydraulic output torque taking into account of the engine output (tm) of the mdps unit; a ball-nut type transmissions (4), in order to generate an output torque, which is of a tie rod (8), which operates to left and right wheel (9a, 9b), since in this transmission the driver torque (td), the engine (tm) and the hydraulic output torque have been entered; and two torsion rods (31, 32) for locking of torque fluctuation rates in those regions of a joint, in that a road surface reaction force (f), which, via the ball-nut type transmissions (4) is transmitted to a steering column, on at least two different positions is detected. Accordingly, are made possible, a that said steering capacity, which, in small, medium and large commercial vehicles is necessary to provide.
