This sub-assembly is formed by two shafts (1, 2), an inner and an outer shaft respectively, of which the surfaces facing one another are in contact locally in the vicinity of diametrically opposite points (16, 18), a space (22) being provided between them between the contact zones. These contact zones (8, 10, 12, 14) are pressed together as a result of force-fitting and elastic deformation, the inner shaft (1) initially having extra thicknesses, while the cavity of the outer shaft has portions narrower than these extra thicknesses. The shafts can, however, shift axially under the effect of a substantial shock. |
