A steering apparatus for vehicles, which comprises: - a steering column having at least one axis of rotation, - a manually actuated steering member mechanical connected to one end of the steering column, - a hydrostatic steering assembly mechanically connected to an opposite end of the steering column and configured to transform a rotation of the steering column around said axis of rotation in a change of an orientation of at least one steering element able to stay in contact with the ground, and - an electric servomechanism configured to apply to the steering column a torque around said axis of rotation, wherein said electric servomechanism comprises a first and a second electric motor (205, 210), each of which is able to apply to the steering column a torque around said axis of rotation independently of the other electric motor, wherein the first electric motor comprises: - a rotor having a pre-set axis of rotation, - a stator that surrounds the rotor, and - a first set of electric coils arranged on the stator angularly equidistant around the axis of the rotor, each of which defines a phase of the first electric motor, wherein the rotor is coaxially associated to the steering column and rotatably integral therewith, so as to define therewith a unitary transmission ratio, characterised in that the steering column consists of a single monolithic body or of multiple bodies mutually connected by means of joints that do not allow the selective interruption of the mechanical connection between said bodies. - a steering column having at least one axis of rotation, - a manually actuated steering member mechanical connected to one end of the steering column, - a hydrostatic steering assembly mechanically connected to an opposite end of the steering column and configured to transform a rotation of the steering column around said axis of rotation in a change of an orientation of at least one steering element able to stay in contact with the ground, and - an electric servomechanism configured to apply to the steering column a torque around said axis of rotation, wherein said electric servomechanism comprises a first and a second electric motor (205, 210), each of which is able to apply to the steering column a torque around said axis of rotation independently of the other electric motor, wherein the first electric motor comprises: - a rotor having a pre-set axis of rotation, - a stator that surrounds the rotor, and - a first set of electric coils arranged on the stator angularly equidistant around the axis of the rotor, each of which defines a phase of the first electric motor, - a rotor having a pre-set axis of rotation, - a stator that surrounds the rotor, and - a first set of electric coils arranged on the stator angularly equidistant around the axis of the rotor, each of which defines a phase of the first electric motor, wherein the rotor is coaxially associated to the steering column and rotatably integral therewith, so as to define therewith a unitary transmission ratio, characterised in that the steering column consists of a single monolithic body or of multiple bodies mutually connected by means of joints that do not allow the selective interruption of the mechanical connection between said bodies.
