Abstract
Description
L'invention concerne un coupleur hydrodynamique utilisé dans les transmissions de mouvement circulaire et en particulier dans les transmissions des véhicules automobiles. The invention relates to a hydrodynamic coupler used in circular motion transmissions and in particular in the transmissions of motor vehicles.
Dans ces transmissions sont utilisés couramment des convertisseurs hydrodynamiques qui interviennent à la fois pour faciliter les changements de rapport en filtrant les irrégularités de couple et pour assurer avec un rendement acceptable une variation continue entre deux rapports. La recherche d'un rendement optimum conduit à verrouiller les convertisseurs par un embrayage en régime In these transmissions are commonly used hydrodynamic converters that intervene both to facilitate gear changes by filtering the irregularities of torque and to ensure with acceptable performance a continuous variation between two ratios. The search for optimum efficiency leads to locking the converters by a clutch in regime
permanent. Ce constat, ajouté au fait que, pour les mêmes raisons le nombre de rapports mécaniques va croissant rend moins nécessaire le recours aux caractéristiques des convertisseurs. L'invention a pour objet une réalisation plus simple exploitant l'interaction de 15 deux turbines dans un circuit de fluide fermé, sans roue de réaction. Les figures 1 et 2 de la planche 1/1 représentent un coupleur à circuit actif axial. 20 Les figures 3 et 4 de la planche 1/1 représentent un coupleur à circuit actif radial. Les figures 5 et 6 de la planche 1/1 représentent un coupleur intégrant un dispositif mécanique amplifiant la différence de vitesse des deux arbres pour 25 compenser le glissement ou accroître le couple transmis. Les figures 1 et 2 de la planche 1/1 représentent un coupleur à turbines axiales, constitué à l'extérieur d'un carter torique (1) réalisé en deux parties centrées et fixées ensemble, solidaires du premier arbre et à l'intérieur d'un moyeu tournant permanent. This observation, added to the fact that, for the same reasons, the number of mechanical ratios is increasing makes it less necessary to use the characteristics of the converters. The subject of the invention is a simpler embodiment exploiting the interaction of two turbines in a closed fluid circuit without a reaction wheel. Figures 1 and 2 of the plate 1/1 represent an axial active circuit coupler. Figures 3 and 4 of Plate 1/1 show a radial active circuit coupler. Figures 5 and 6 of the plate 1/1 show a coupler incorporating a mechanical device amplifying the speed difference of the two shafts to compensate for the slip or increase the torque transmitted. FIGS. 1 and 2 of the plate 1/1 represent an axial turbine coupling, constituted outside of an O-ring (1) made in two parts centered and fixed together, integral with the first shaft and inside the 'a rotating hub
30 (2) solidaire du deuxième arbre. 30 (2) integral with the second shaft.
Le carter (1) et le moyeu tournant (2) sont liés en rotation par deux paliers The housing (1) and the rotating hub (2) are connected in rotation by two bearings
tournants (5), le joint tournant (6) assurant l'étanchéité au fluide contenu dans (1). Le carter (1) porte la turbine double (3) qui comporte deux parties cylindriques 5 (3-1) et (3-2) dont les parois tubulaires sont reliées par des aubes inclinées sur l'axe turners (5), the rotary joint (6) sealing the fluid contained in (1). The casing (1) carries the double turbine (3) which comprises two cylindrical parts (3-1) and (3-2) whose tubular walls are connected by vanes inclined on the axis
principal, dans un sens dans (3-1), dans le sens opposé dans (3-2). Le moyeu tournant (2) porte une autre turbine (4) qui comporte deux parties (4.1) et (4.2) semblables respectivement à (3.1) et (3.2) dont l'action est identique à 10 celle de la turbine (3). L'intérieur du carter (1) et les parois tubulaires des deux turbines (3) et (4) délimitent un circuit fermé de section constante. 15 Les fonds du carter (1) constituent des zones de rebroussement dont la section offerte aux flux courbe est constante. La partie occupée par les turbines (3) et (4) constitue la zone active : le flux axial généré par la turbine motrice entraine l'autre et les rôles réciproques peuvent être inversés. 20 Les turbines (3.2) et 4.2) ou (3.1) et (4.1) sont optionnelles et la zone qu'elles occupent laissée libre pour le circuit de retour. Dans ce cas la capacité de couple transmis est divisée par deux. En se reportant aux figures 3 et 4 de la planche 1/1 on a représenté un principal, in a sense in (3-1), in the opposite direction in (3-2). The rotating hub (2) carries another turbine (4) which has two parts (4.1) and (4.2) similar respectively to (3.1) and (3.2) whose action is identical to that of the turbine (3). The interior of the casing (1) and the tubular walls of the two turbines (3) and (4) delimit a closed circuit of constant section. The crankcase bottoms (1) constitute cusp zones whose section offered to curved flows is constant. The part occupied by the turbines (3) and (4) constitutes the active zone: the axial flow generated by the driving turbine drives the other and the reciprocal roles can be reversed. The turbines (3.2) and 4.2) or (3.1) and (4.1) are optional and the area they occupy left free for the return circuit. In this case the transmitted torque capacity is divided by two. Referring to FIGS. 3 and 4 of plate 1/1, there is shown a
25 coupleur de même principe mais à circulation active radiale. Le carter torique (11) à section en forme de poire délimite le circuit fermé de section constante, le flasque (13) dépendant du carter torique (11) porte les turbines (13-1) et (13-2) symétriques l'une de l'autre mais à inclinaison d'aubes inversées, le flasque (14) dépendant du moyeu tournant (12) porte les turbines (14-1) et (14-2) symétriques l'une de l'autre et à Coupler of the same principle but with radial active circulation. The pear-shaped section housing (11) delimits the closed circuit of constant section, the flange (13) depending on the O-ring housing (11) carries the symmetrical turbines (13-1) and (13-2). on the other but with an inclination of inverted blades, the flange (14) depending on the rotating hub (12) carries the turbines (14-1) and (14-2) symmetrical to each other and to
30 inclinaison d'aubes inversées par rapport à celles en vis-à-vis. Inclination of blades reversed compared to those vis-à-vis.
Comme dans le cas des figures 1 et 2, les turbines (13.1) et (13.2) ou (14.1) et (14.2) sont optionnelles ce qui correspond à la figure 5. Les zones de rebroussement du carter (11) sont ajourées pour assurer la 5 continuité du circuit. Les figures 5 et 6 de la planche 1/1 représentent un coupleur intégrant un dispositif mécanique amplifiant la différence de vitesse entre les deux arbres et accroissant ainsi, pour un dimensionnement donné des turbines, le couple transmis. As in the case of Figures 1 and 2, the turbines (13.1) and (13.2) or (14.1) and (14.2) are optional which corresponds to Figure 5. The crush areas of the housing (11) are perforated to ensure the continuity of the circuit. Figures 5 and 6 of the plate 1/1 show a coupler incorporating a mechanical device amplifying the speed difference between the two shafts and thus increasing, for a given size of the turbines, the transmitted torque.
10 Ce dispositif permet en particulier de compenser un glissement non souhaité entre les deux arbres menant et mené. Le moyeu (22) comporte au moins un maneton (22-2) autour duquel tourne le pignon satellite (25) qui engrène, à l'extérieur avec la couronne planétaire (26) solidaire du carter (21) et à l'intérieur avec le pignon planétaire (27) qui dépend de la paroi (15) sur laquelle est la turbine (15-1). Du carter This device makes it possible in particular to compensate for an undesired slip between the two driving and driven shafts. The hub (22) comprises at least one crankpin (22-2) around which the planet gear (25) which meshes with the planet gear (26) integral with the crankcase (21) and internally with the sun gear (27) which depends on the wall (15) on which is the turbine (15-1). From the crankcase
15 (21) dépend la paroi (16) portant la turbine (16-1). On optimise l'efficience des turbines (15-1), en rendant, en chaque point d'une aube, l'angle de sa surface avec le plan passant par l'axe de rotation inversement proportionnel à son rayon, d'où une forme complexe. S'agissant des coupleurs à 15 (21) depends on the wall (16) carrying the turbine (16-1). The efficiency of the turbines (15-1) is optimized by making, at each point of a blade, the angle of its surface with the plane passing through the axis of rotation inversely proportional to its radius, hence a complex shape. With regard to couplers
20 turbine radiale, le profil des conduits dans la zone active doit être un hyperboloïde dont l'axe de rotation est une asymptote. Si les coupleurs ne doivent être sollicités que de façon intermittente, leur rendement est secondaire et la forme des aubes et des conduits peut être définie uniquement en fonction de considérations de fabrication. 20 radial turbine, the profile of the ducts in the active zone must be a hyperboloid whose axis of rotation is an asymptote. If the couplers only need to be intermittently solicited, their performance is secondary and the shape of the blades and ducts can be defined solely on the basis of manufacturing considerations.
