Title
(EN) TORQUE TRANSMISSION ARRANGEMENT
(FR) AGENCEMENT DE TRANSMISSION DE COUPLE
Abstract
(EN)
A torque transmission arrangement comprises a cylindrical friction element carrier (11) and a snap-ring (12), wherein the friction element carrier (11) is configured for carrying at least a pressing plate (20) and a reaction plate (21) of an outer friction-based torque-transmission mechanism (13) rotationally secured to an outer surface of the friction element carrier (11) and at least a pressing plate (22) and a reaction plate (23) of an inner friction-based torque-transmission mechanism (14) rotationally secured to an inner surface of the friction element carrier (11), wherein the cylindrical friction element carrier (11) comprises a plurality of through-holes (15) distributed around the circumference of the friction element carrier (11), and wherein the snap-ring (12) comprises a plurality of radial projections (16) distributed around the inner or outer circumference of the snap-ring (12) and configured to extend through said through-holes (15) when the snap-ring (12) is mounted on the friction element carrier (11), such that the snap-ring (12) when mounted on the friction element carrier (11) protrudes in a radial direction beyond both the inner and outer surfaces of the friction element carrier (11) for retaining the inner and outer reaction plates (21, 23) of the inner and outer friction-based torque-transmission mechanisms (13, 14) on the friction element carrier (11). A method for manufacturing such a torque transmission arrangement is also provided.

La présente invention concerne un agencement de transmission de couple comprenant un support d'élément de friction cylindrique (11) et un anneau d'encliquetage (12), le support d'élément de friction (11) étant configuré pour porter au moins une plaque de pression (20) et une plaque de réaction (21) d'un mécanisme de transmission de couple reposant sur une friction externe (13) fixé en rotation à une surface externe du support d'élément de friction (11) et au moins une plaque de pression (22) et une plaque de réaction (23) d'un mécanisme de transmission de couple reposant sur une friction interne (14) fixé en rotation à une surface interne du support d'élément de friction (11), le support d'élément de friction cylindrique (11) comprenant une pluralité de trous traversants (15) répartis autour de la circonférence du support d'élément de friction (11), et l'anneau d'encliquetage (12) comprenant une pluralité de saillies radiales (16) réparties autour de la circonférence interne ou externe de l'anneau d'encliquetage (12) et configuré pour s'étendre à travers lesdits trous traversants (15) lorsque l'anneau d'encliquetage (12) est monté sur le support d'élément de friction (11), de sorte que l'anneau d'encliquetage (12) lorsqu'il est monté sur le support d'élément de friction (11), fait saillie dans une direction radiale au-delà des surfaces interne et externe du support d'élément de friction (11) pour retenir les plaques de réaction interne et externe (21, 23) des mécanismes de transmission de couple reposant sur une friction interne et externe (13, 14) sur le support d'élément de friction (11). L'invention concerne également un procédé de fabrication d'un tel agencement de transmission de couple.
