Abstract

The lateral thrust system consists of a pair of wedge-shaped friction members (5) that are pushed in opposite directions by a spring (6) so that they interact with the sloping surfaces of seats (4) fixed to the wagon's bogie. The lateral thrust system consists of a pair of wedge-shaped friction members (5) that are pushed in opposite directions by a spring (6) so that they interact with the sloping surfaces of seats (4) fixed to the wagon's bogie. Each of the seats has a central opening dividing it into two sliders with surfaces inclined inwards an angle with its apex lying on the seat's axis. The spring, made from two elastomer elements (18), has a rod with its two ends inside the wedges, passing through polymer guide rings.

Description

ii

Chaque extrémité de la caisse d'un wagon repose sur son bogie, par l'intermédiaire d'un pivotement central. De part et d'autre de ce pivot sont disposés des appuis latéraux, fixes à l'origine, ils sont devenus élastiques avec l'augmentation des vitesses de circulation. Ils ont pour rôle supplémentaire de freiner le lacet du bogie.  Each end of a wagon's body rests on its bogie, through a central pivot. On either side of this pivot are arranged lateral supports, originally fixed, they became elastic with the increase of the speed of circulation. Their additional role is to brake the bogie lash.

Les jeux ( j) ou les débattements latéraux au droit de ces appuis sont déterminants pour garantir la circulation du wagon (voir figure I).  The games (j) or the lateral deflections at the right of these supports are decisive to guarantee the circulation of the wagon (see figure I).

Les appuis latéraux des bogies (1), s'ils sont fixes, ils sont recouverts d'un glissoir en acier qui frottent temporairement sur la partie correspondante (2) fixée 10 sous la caisse du wagon. En équilibre parfait, le jeux (j) est égal de part et d'autre du pivot. S'ils sont élastiques, ils sont en contact constant avec le glissoir de caisse (2) et sont recouverts d'un glissoir en matière synthétique qui maintient un frottement constant entre bogie et caisse. Leur débattement vertical respecte le jeu (j) précédemment mentionné.  The side supports of the bogies (1), if they are fixed, they are covered with a steel slider which rubs temporarily on the corresponding part (2) fixed 10 under the body of the wagon. In perfect balance, the game (j) is equal on both sides of the pivot. If they are elastic, they are in constant contact with the body slider (2) and are covered with a plastic slider which maintains a constant friction between bogie and body. Their vertical movement respects the game (j) mentioned above.

Les appuis latéraux ou lisoirs élastiques connus à ce jour sont généralement composés d'un siège fixé au bogie et d'une glissière. La glissière reçoit la garniture de frottement, elle est appliquée contre le glissoir de caisse par l'action de deux ressorts à l'intérieur desquels sont disposés les butées qui limitent le débattement de la caisse. Le siège et la glissière dispose respectivement d'un double arrêt vertical et 20 d'une tenon qui conjugués permettent de générer l'effort de frottement nécessaire.  The lateral supports or elastic lugs known to date are generally composed of a seat attached to the bogie and a slide. The slide receives the friction lining, it is applied against the body slider by the action of two springs within which are disposed the stops which limit the movement of the body. The seat and the slideway respectively have a double vertical stop and a tenon which conjugates make it possible to generate the necessary friction force.

Ces moyens nécessitent cependant un minimum de jeu de fonctionnement qui avec l'accroissement des vitesses de circulation des wagons deviennent préjudiciables.  These means, however, require a minimum of operating clearance which with the increase of the speed of circulation of the cars become detrimental.

Un autre mode de réalisation consiste en deux blocs élastiques, inclinés en opposition et coiffés par le glissoir. Cette disposition n'est pas compatible avec 25 l'espace standard réservé à ce type de matériel.  Another embodiment consists of two elastic blocks, inclined in opposition and capped by the slide. This arrangement is not compatible with the standard space reserved for this type of material.

La figure I représente schématiquement le pivotement d'un wagon La figure II représente une vue en élévation du lisoir La figure III représente un éclaté du lisoir La figure IV représente une coupe suivant AA du lisoir La figure V représente une vue de dessus de la glissière seule La présente invention décrit un lisoir élastique qui assure toutes les fonctions habituelles d'un tel matériel en annulant les jeux longitudinaux dans l'axe du lisoir et donc les risques de lacet.  Figure I shows schematically the pivoting of a wagon Figure II shows an elevational view of the slider Figure III shows an exploded of the slider Figure IV shows a section along AA of the slider Figure V shows a top view of the slider The present invention only discloses an elastic lug which provides all the usual functions of such a material by canceling the longitudinal clearances in the axis of the liner and therefore the risk of yaw.

Il se compose d'un siège (3) qui présente à sa partie inférieure une face 35 identique au lisoir standardisé et à sa partie supérieure, deux rampes (4) disposées en vis-à-vis et sur lesquelles coulissent deux coins (5). Entre les deux coins (5) est disposé un élément élastique (6).  It consists of a seat (3) which has at its lower part a face 35 identical to the standardized light and its upper part, two ramps (4) arranged vis-à-vis and on which slide two corners (5) . Between the two corners (5) is disposed an elastic member (6).

Les rampes (4) du siège (3) sont ouvertes par une lumière (7) disposée suivant l'axe longitudinal de la pièce, partageant ainsi les rampes (4) en deux 40 glissières (4') et (4"). Elles sont inclinées pour former entre elles un angle f3 ouvert vers le haut et dont le sommet suit l'axe longitudinal du lisoir. De plus les glissières (4') et (4") suivant leur plan médian présentent une face convexe de rayon R. Chacun des coins (5) repose sur le siège (3) par son plan incliné (8) au milieu duquel un talon (9) partage le plan (8) en deux glissières (8') et (8") qui chacune 45 sont inclinées vers le talon (9) pour former un V d'angle 13 correspondant à celui de la glissière.  The ramps (4) of the seat (3) are opened by a lumen (7) arranged along the longitudinal axis of the part, thus sharing the ramps (4) in two slideways (4 ') and (4 "). are inclined to form an upwardly open angle f 3 between them, the top of which follows the longitudinal axis of the lip, and the slides (4 ') and (4 ") along their median plane have a convex face of radius R. Each of the corners (5) rests on the seat (3) by its inclined plane (8) in the middle of which a heel (9) divides the plane (8) into two slides (8 ') and (8 ") each of which 45 are inclined towards the heel (9) to form an angle V 13 corresponding to that of the slide.

Le talon (9) est guidé par la lumière (7), il est plus étroit que cette dernière pour garantir un jeu de 2 fois x. Chaque coin (5) reçoit sur sa face supérieure (10) une garniture de frottement (11). Sur sa face frontale (12) est aménagée une cavité 50 (13) au centre de laquelle est percé un trou borgne (14) bordé par une bague de polyamide (15). L'élément élastique (6) est constitué d'une tige (16) dont chacune de ses extrémités est engagée dans la bague (15) de chacun des coins (5). Elle porte en son centre une rondelle (17) solidaire de la tige (16) sur laquelle s'appuie une face de chacun des ressorts (18) dont l'autre face réagit respectivement sur chacun des coins (5). Ils sont en élastomère et assurent ainsi l'étanchéité autour du trou (14).  The heel (9) is guided by the light (7), it is narrower than the latter to guarantee a game of 2 times x. Each corner (5) receives on its upper face (10) a friction lining (11). On its front face (12) is arranged a cavity 50 (13) in the center of which is drilled a blind hole (14) bordered by a polyamide ring (15). The elastic element (6) consists of a rod (16) whose each end is engaged in the ring (15) of each of the corners (5). It carries in its center a washer (17) secured to the rod (16) on which rests a face of each of the springs (18), the other side reacts respectively on each of the corners (5). They are made of elastomer and thus seal around the hole (14).

Le wagon est en équilibre sur son pivot. Au niveau de chaque lisoir, sous l'action du ressort (6) et des rampes (4), chacun des coins (5) exerce une force constante sous le glissoir de la caisse du wagon assurant ainsi le frottement nécessaire pour stabiliser le bogie.  The car is balanced on its pivot. At each level, under the action of the spring (6) and ramps (4), each of the corners (5) exerts a constant force under the slider of the car body thus ensuring the friction necessary to stabilize the bogie.

Lors du basculement du wagon, la caisse s'incline, surcharge l'un des lisoirs et soulage l'autre. Sur le lisoir surchargé, les deux coins (5) sont descendus le long de la rampe (4) pour se contacter par leur face frontale (12) limitant le basculement du wagon. Dans cette configuration, les ressorts en élastomère (18) sont écrasés et se logent à l'intérieur des cavités (13) des coins (5). Pendant l'opération, les coins (5) se 15 sont déplacés transversalement pour leur permettre de suivre l'inclinaison de la caisse du wagon par le jeu des rampes (4') (4") et (8') (8").  When tilting the wagon, the body tilts, overloads one of the lugs and relieves the other. On the overloaded buffer, the two corners (5) are lowered along the ramp (4) to contact their front face (12) limiting the tilting of the wagon. In this configuration, the elastomeric springs (18) are crushed and are housed within the cavities (13) of the corners (5). During the operation, the wedges (5) are moved transversely to enable them to follow the inclination of the car body by the play of the ramps (4 ') (4 ") and (8') (8") .

Sur le lisoir opposé, celui qui est soulagé, sous l'action des ressorts (18) les coins (5) sont repoussés le long des rampes (4) pour maintenir le contact avec le glissoir de caisse. Là encore, les coins (5) se sont déplacés transversalement pour 20 que, par le jeu des rampes (4') (4") et (8') (8") ils puissent s'incliner et maintenir un contact constant et complet avec le glissoir de caisse.  On the opposite side, which is relieved, under the action of the springs (18) the corners (5) are pushed along the ramps (4) to maintain contact with the body slider. Again, the wedges (5) have moved transversely so that, by the play of the ramps (4 ') (4 ") and (8') (8") they can tilt and maintain a constant and complete contact with the cash slider.

Par ailleurs, le talon (9) présente une hauteur supérieure à sa partie arrière afin qu'en cas de défaillance complète des ressorts (18), sur le lisoir, dans sa configuration soulagée, les deux coins (5) ne puissent se dégager lors d'un choc 25 vertical.  Furthermore, the heel (9) has a height greater than its rear portion so that in the event of complete failure of the springs (18), on the lip, in its relieved configuration, the two corners (5) can not be released during of a vertical shock.
