A torque transmitting structure for an automatic transmission has an inner hub for rotating the structure and an outer annular shell. The annular shell has an internal radial spline portion, an external brake surface, a torque tube and an axially facing drive connecting surface. The annular shell is manufactured in a flow forming process, wherein a cup-shaped blank is secured on a mandrel which has a shape complementary to the internal shape of the shell. Forming rolls engage the outer surface and are moved axially relative to the mandrel in a manner to form the desired outer contour of the shell. After the flow forming operation, the shell is removed from the mandrel, the axial drive connection is formed by metal removal and the hub is bonded to the shell.

Une structure de transmission de couple pour boîte de vitesses automatique a un moyeu pour faire tourner la structure et une coquille annulaire extérieure. La coquille annulaire a une partie intérieure à nervures radiales, une surface extérieure de freinage, un tube de poussée et une surface d'accouplement de transmission lui faisant face axialement. La coquille annulaire est fabriquée suivant un procédé de fluotournage dans lequel un flan en forme de coupelle est fixé sur un mandrin qui a une forme complémentaire à la forme intérieure de la coquille. Des rouleaux de profilage se mettent en prise sur la surface extérieure et se déplacent axialement par rapport au mandrin de manière à donner à la coquille le profil extérieur voulu. Après le fluotournage, la coquille est retirée du mandrin, l'accouplement de transmission axial est formé par enlèvement de métal et le moyeu est assujetti à la coquille.
