CA 2264061

A sheet metal inner torque transmitting member (38) in or for a multiple plate clutch or brake (28) comprises a corrugated cylinder having external tooth surfaces (58) for mating with one group (48) of the multiple plates (44), and internal trough surfaces (60), with holes (62) therebetween to allow a radially outward flow of coolant or lubricant. At the free end (68) of the trough surfaces (60), a dam structure (64) is provided, by axially upsetting material (at 66) from the end of the trough surfaces (60), so that the external tooth surfaces (58) are not shortened.

Un élément interne métallique et en feuille (38) pour la transmission de couple, placé dans un frein ou un embrayage à plusieurs disques (28), comprend un cylindre ondulé présentant des surfaces à dents extérieures (58) destinées à venir en prise avec un groupe (48) des disques multiples (44), des surfaces interne en forme d'auge (60) entre lesquelles sont prévus des orifices (62) afin de permettre un écoulement centrifuge du fluide de refroidissement ou de lubrification. Au niveau des extrémités libres (68) des surfaces en auge (60), une structure de barrage (64) est formée, par refoulage axial d'un matériau (66) depuis l'extrémité des surfaces en auge (60) de sorte que la taille des surfaces à dents extérieures (58) ne soient pas réduite.
