Method of fastening a cross-member to an arm and a semi-rigid axle made by the method

A process for fabricating an axle that includes a cross-member and arms which are assembled to extremities of the cross-member, said process comprising:

• forming a cross-member with an extremity and at least one arm having a socket;
• arranging, in a fastening position, the extremity of the cross-member within the socket of the at least one arm;
• adjusting a relative position of the cross-member and the at least one arm prior to fastening the extremity to the socket;
• and
• fastening together in a rigid manner, at an adjusted position, the extremity of the cross-member and the socket of the at least one arm using a magneto-forming process;
• wherein the fastening occurs while the cross-member and the at least one arm are in the fastening position and results in interfering contact between an outer surface of the extremity and an inner surface of the socket,
• wherein at least one of the cross-member and the at least one arm comprise at least one metallic material,
• wherein the extremity comprises a protuberance, and
• wherein the fastening comprises subjecting the protuberance of the cross-member to radial deformation using the magneto-forming process.
