A method for neutralizing transient forces generated by a rise of at least one sudden jolt in a steering column of a vehicle, said transient forces being transmitted from its distal end to a steering device for controlling the trajectory followed by the vehicle which is mounted on a proximal end of the column characterized in that according to this method, the following operations are performed: - in a state of coaxial coupling on a central axis (A1) of the column , mounting, in accordance with a reference torque, via a mobile coupling link , at least two sections of column , a distal section with a proximal section which is rotationally integral with the control device, and providing a pre-stressed elastic region axially between the sections mounted in the coupling state in accordance with the reference torque, - under the effect of a start of rotation of the distal section by a transient torque (C1) greater than the reference torque, causing an automatic decoupling between the distal and proximal sections by rotationally driving the coupling link subjected to the transient torque (C1) and by helical guidance of this link in the proximal section , and - simultaneously, under the effect of the decoupling between the sections , driving the coupling link in translation by axial guidance on the section combined with helical guidance in the distal section to the axial region so as to compress the latter axially between the sections , the compression being greater than a compression threshold corresponding to its prestressing, then - as a result of the cessation of the jolt and correlatively of the exhaustion of the transient forces, causing an automatic re-coupling between the sections by relaxing the compressed elastic region , said region being returned to its pre-stressing threshold between the sections coupled under the reference torque and the coupling link being returned to the state of coupling of the sections with each other. - in a state of coaxial coupling on a central axis (A1) of the column , mounting, in accordance with a reference torque, via a mobile coupling link , at least two sections of column , a distal section with a proximal section which is rotationally integral with the control device, and providing a pre-stressed elastic region axially between the sections mounted in the coupling state in accordance with the reference torque, - under the effect of a start of rotation of the distal section by a transient torque (C1) greater than the reference torque, causing an automatic decoupling between the distal and proximal sections by rotationally driving the coupling link subjected to the transient torque (C1) and by helical guidance of this link in the proximal section , and - simultaneously, under the effect of the decoupling between the sections , driving the coupling link in translation by axial guidance on the section combined with helical guidance in the distal section to the axial region so as to compress the latter axially between the sections , the compression being greater than a compression threshold corresponding to its prestressing, then - as a result of the cessation of the jolt and correlatively of the exhaustion of the transient forces, causing an automatic re-coupling between the sections by relaxing the compressed elastic region , said region being returned to its pre-stressing threshold between the sections coupled under the reference torque and the coupling link being returned to the state of coupling of the sections with each other. <EOS>
