<p>An assembly is formed between a shaft (5) and a jaw (4) of a universal joint. The jaw is formed by a metal part defining a reference geometrical axis (X-X) and having one end shaped so as to define two legs (4.1) for mounting a cross member of a universal joint and clearance cutouts (4.2), a second end forming a cylindrical hub (4.4), an elastic sleeve (9) being fitted onto the shaft (5) and into the hub (4.4). The shaft has one tubular axial end which protrudes from the elastic sleeve (9) towards the legs (4.1), the tubular end of the shaft (5) having at least one locating ridge (5.3) arranged laterally opposite and at a distance from at least one complementary ridge (4.7) of the jaw, the locating ridge (5.3) and the complementary ridge (4.7) being shaped so as to be able to interpenetrate by means of a relative axial movement between the shaft (5) and the jaw (4) in order to limit the relative rotational movement between the shaft (5) and the jaw (4) about the reference axis and in order to limit the relative axial movement between the shaft (5) and the jaw (4) in a direction of interpenetration. The jaw (4) further comprises an intermediate partition (4.5) which extends perpendicularly to the reference axis (X-X) in an intermediate position between the hub (4.4) and the legs (4.1), the intermediate partition (4.5) partially closing the hub and being provided with a through-hole (4.6) for the tubular end of the shaft, wherein the tubular end of the shaft has, at least locally, a tab of material (5.4) which is folded radially outwards so as to form an axial stop engaging with the intermediate partition (4.5) in order to limit the relative axial movement between the shaft and the jaw in a direction of extraction opposite to the direction of interpenetration.</p> |
