"Anneau conique dans des dispositifs de synchronisation pour des boîtes de vitesses notamment pour véhicules  "Conical ring in synchronization devices for gearboxes in particular for vehicles

automobiles ".automobiles ".

Domaine d'application de l'invention: L'invention concerne un anneau conique dans des dispositifs de synchronisation pour des boîtes de vitesses, notamment pour véhicules automobiles, anneau disposé supplémentairement en flottant librement entre l'anneau de synchronisation proprement dit, monté flottant et comportant un cone interne, et la surface conique de friction de la roue dentée qui lui est associée, et dont la  FIELD OF APPLICATION OF THE INVENTION The invention relates to a conical ring in synchronization devices for gearboxes, in particular for motor vehicles, which ring is additionally freely floating between the synchronization ring proper, mounted floating and having an internal cone, and the conical friction surface of the toothed wheel associated therewith, and whose

synchronisation doit être obtenue.synchronization must be obtained.

Caractéristiques des solutions techniques connues: On connait des dispositifs de synchronisation dans lesquels, de préférence, l'anneau de synchronisation monté flottant est revêtu-d'un métal se caractérisant par une dureté superficielle élevée et également un bon comportement en cas de lubrification insuffisante, pour obtenir dans la coopération avec la surface de friction durcie de la roue dentée associée, et dont la synchronisation doit être obtenue, aussi bien un coefficient de frottement élevé qu'également une longue durée de vie  Characteristics of the known technical solutions: Synchronization devices are known in which, preferably, the floating mounted synchronization ring is coated with a metal characterized by a high surface hardness and also a good behavior in case of insufficient lubrication, to obtain in cooperation with the hardened friction surface of the associated toothed wheel, and whose synchronization must be obtained, both a high coefficient of friction and a long service life

des surfaces frottantes dans les conditions du frottement 25 mixte et partiellement du frottement a sec.  friction surfaces under the conditions of mixed friction and partially dry friction.

Le défaut des dispositifs de synchronisation de ce type de construction réside dans les coûts de réalisation élevés des anneaux de synchronisation car pour obtenir la dureté superficielle élevée et un bon comportement dans le cas d'une lubrification insuffisante, les métaux 5 de revêtement appropries sont très coûteux et mettent en oeuvre des technologies de préparation spéciales pour la réalisation des granules ainsi que des technologies de  The defect of the synchronization devices of this type of construction lies in the high realization costs of the synchronization rings because to obtain the high surface hardness and good behavior in the case of insufficient lubrication, the appropriate coating metals are very high. costly and use special preparation technologies for the production of granules as well as

revêtement particulières.special coating.

En outre, ces anneaux de synchronisation comportent 10 l'inconvénient que seule l'unique surface de leur enveloppe interne est disponible comme surface d'usure.  In addition, these timing rings have the disadvantage that only the single surface of their inner envelope is available as a wear surface.

But de l'invention: Le but de l'invention est d'éviter les inconvénients précités, de réduire la dépense technologique de réalisa15 tion des dispositifs habituels de synchronisation et  OBJECT OF THE INVENTION The object of the invention is to avoid the aforementioned drawbacks, to reduce the technological expense of realizing the usual synchronization devices and

d'économiser surtout les matériaux métalliques coûteux.  save mostly expensive metal materials.

Exposé de la nature de l'invention: Le problème de base de l'invention est de créer un anneau conique qui minimise les coûts de réalisation élevés des dispositifs de synchronisation connus et qui, en même temps, permettent des durées de vie plus élevées  DESCRIPTION OF THE NATURE OF THE INVENTION The basic problem of the invention is to create a conical ring which minimizes the high realization costs of the known synchronization devices and which, at the same time, allow longer lifetimes.

comparativement aux dispositifs de synchronisation connus.  compared to known synchronization devices.

Conformément à l'invention, ce problème est résolu en ce que, un autre anneau conique est disposé entre l'anneau de synchronisation proprement dit, monté flottant, dont le cône interne ne nécessite désormais aucun revêtement d'un métal se caractérisant par une duree superficielle élevée, avec un bon comportement en cas de lubrification insuffisante, et la surface de friction 30 conique de la roue dentée associee, dont la synchronisation doit être obtenue, cet autre anneau conique, de préférence flottant librement, en un matériau bon marche présentant un bon comportement en cas de lubrification insuffisante et un bon coefficient de frottement, par exemple un métal lourd non ferreux, la surface externe de cet anneau supplémentaire venant en contact de frottement avec le cône interne de l'anneau de synchronisation, tandis que sa surface interne vient en contact de frottement avec le cône externe de la roue dentée associée, de sorte que chacune de ces surfaces de frottement de l'anneau conique, supporte seulement à peu près la moitié de la  According to the invention, this problem is solved in that another conical ring is disposed between the synchronization ring itself, mounted floating, whose inner cone now requires no coating of a metal characterized by a duration high surface area, with good behavior in case of insufficient lubrication, and the conical friction surface of the associated toothed wheel, whose synchronization must be obtained, this other conical ring, preferably free floating, in a cheap material having a good behavior in case of insufficient lubrication and a good coefficient of friction, for example a non-ferrous heavy metal, the external surface of this additional ring coming into frictional contact with the internal cone of the synchronization ring, while its internal surface comes into frictional contact with the outer cone of the associated toothed wheel, so that each of these surfaces of friction of the conical ring, supports only about half of the

Entre l'anneau de synchronisation 1 et le cône de synchronisation 2, dont la denture interne 3 est en liai15 son d'entraînement avec la roue dentée associée 4 dont la synchronisation doit être obtenue, est disposé, flottant, l'anneau conique 5 Dès que l'anneau de synchronisation 1 par actionnement du manchon de commutation 7 guidé sur le support de manchon 6 est enclenché dans sa 20 position de blocage et que le processus de frottement visant à obtenir une synchronisation entre le support de manchon 6 et le cône de synchronisation 2 est engagé, l'anneau de synchronisation 1 s'applique par sa surface conique interne sur la surface conique externe de l'an25 neau conique 5 flottant librement, et dont la surface conique interne s'applique alors sur la surface conique  Between the synchronizing ring 1 and the synchronizing cone 2, the internal toothing 3 of which is in communication with the associated toothed wheel 4, the synchronization of which must be obtained, the conical ring 5 is arranged, floating. that the synchronizing ring 1 by actuating the switching sleeve 7 guided on the sleeve support 6 is engaged in its blocking position and that the friction process for synchronizing between the sleeve support 6 and the cone of When synchronization 2 is engaged, the synchronization ring 1 is applied by its internal conical surface to the outer conical surface of the conically flowing free-flowing conical surface 5, and its internal conical surface then applies to the conical surface.

Du fait des couples de frottement agissant entre  Due to the friction couples acting between

les surfaces coniques en contact, on parvient au synchro30 nisme recherché entre le support de manchon 6 et le cône de synchronisation 2.  With the conical surfaces in contact, the desired synchrony between the sleeve support 6 and the synchronization cone 2 is achieved.
