Ilest également conrife/donner à la mâchoire une forme générale cylindrique pour obtenir une meilleure rigidité ainsi qu'une hauteur d'appui pe and deformation of a sheet blank or a section of tube. It is also conrified / give the jaw a generally cylindrical shape to obtain better rigidity as well as a support height
suffisante pour les cuvettes destinées à coiffer les tourillons du croisillon. sufficient for the bowls intended to cap the spider pins.
En raison d'impératifs imposant une diminution du poids et/ou du prix de revient, il est parfois nécessaire d'utiliser un flan ou un tube mince pour la réalisation de telles mâchoires qui, malgré leur forme courbe, et notamment cylindrique, ne permettent plus d'obtenir un alésage de hauteur Due to imperatives imposing a reduction in weight and / or cost, it is sometimes necessary to use a blank or a thin tube for the production of such jaws which, despite their curved shape, and in particular cylindrical, do not allow more to get a height bore
suffisante pour offrir l'appui nécessaire aux cuvettes. sufficient to provide the necessary support for the bowls.
La présente invention a essentiellement pour but de remédier aux inconvénients précités et d'étendre l'emploi des cardans possèdant les formes avantageuses précitées à des applications nécessitant l'emploi d'une The main object of the present invention is to remedy the aforementioned drawbacks and to extend the use of cardan shafts having the above-mentioned advantageous forms to applications requiring the use of a

branches dont au moins une portion présente une forme générale courbe, mu- branches of which at least a portion has a generally curved, mu-
nie d'un alésage réalisé dans l'épaisseur de la tôle, caractérisée en ce que l'alésage précité se prolonge par une cheminée d'allure générale cylindrique pour offrir une hauteur d'appui suffisante à une cuvette destinée à coiffer le nie of a bore made in the thickness of the sheet, characterized in that the aforementioned bore is extended by a generally cylindrical chimney to provide sufficient support height to a bowl intended to cap the
tourillon d'un croisillon.pin of a crosspiece.
Selon une première caractéristique de l'invention, l'extrémité de la cheminée qui s'élève au-dessus de la surface de la branche comporte un épaulement formant une butée radiale, pour la cuvette destinée à According to a first characteristic of the invention, the end of the chimney which rises above the surface of the branch comprises a shoulder forming a radial stop, for the bowl intended for

Selon une autre caractéristique de l'invention, la cheminée est, soit externe et s'élève donc au-dessus de la face de la mâchoire opposée à According to another characteristic of the invention, the chimney is either external and therefore rises above the face of the jaw opposite to
celle disposée du côté du croisillon, soit interne. that arranged on the side of the cross, is internal.
