Description
DISPOSITIF D'ARTICULATION POUR UN TRAIN ROULANT. ARTICULATION DEVICE FOR A ROLLING TRAIN.
La présente invention s'applique à l'articulation d'un train roulant, tel que'l'essieu arrière d'un véhicule automobile, sur un axe solidaire du chassis du véhicule, au moyen de bras support de roue qui sont articulés soit individuellement sur l'axe dans le cas d'une suspension arrière à roues indépendantes, soit le plus couramment,au moyen d'un faux essieu de liaison des deux roues arrière formant une sorte de châssis de liaison en
H des deùx roues arrière.The present invention applies to the articulation of a running gear, such as the rear axle of a motor vehicle, on an axis integral with the chassis of the vehicle, by means of wheel support arms which are articulated either individually. on the axle in the case of a rear suspension with independent wheels, that is most commonly, by means of a false axle connecting the two rear wheels forming a sort of connecting chassis in
H of the two rear wheels.
Selon ce dernier modederéalisation largement utilisé dans la construction automobile car il assure un guidage suffisant de l'essieu arrière pour un coût de realisation relativement modique, de courts prolongements des barres du H de la liaison des roues, sont articulés chacun sur un axe solidaire du châssis du véhicule au moyen d'une liaison annulaire en élastomère formant un bloc amortisseur de vibration du type silent-bloc qui autorise les débattements du chassis en H de liaison des deux roues arrière, à la fois en rotation, en torsion de flexion et même en déplacement transversal, sans nécessiter des moyens d'articulation onéreux du type roulement à billes ou à rouleaux. According to this latter embodiment widely used in automobile construction since it provides sufficient guidance of the rear axle for a relatively low production cost, short extensions of the bars of the H of the wheel connection, are each articulated on an axis integral with the chassis of the vehicle by means of an annular elastomer connection forming a vibration-absorbing block of the silent-block type which allows the deflections of the H-shaped chassis connecting the two rear wheels, both in rotation, in torsional bending and even in transverse movement, without requiring expensive articulation means of the ball or roller bearing type.
Ce mode de suspension de l'essieu arrière à l'aide d'un châssis de liaison en H ne peut cependant pas donner au véhicule des qualités de tenue de route en virage qui soient équivalentes à celles des suspensions arrière à roues indépendantes car -les débattements du châssis en H provoquent, lorsque le véhicule équipé de ce type de suspension arrière roule en virage, des variations de dérive qui affectent sérieusement la tenue de route du véhicule lorsqu'on la sollicite en virage.Les variations de dérive de l'essieu arrière conduisent généralenent le véhicule à présenter un comportement survireur qui nécessite de la part du conducteur, lorsqu'il pousse le véhicule vers ses limites de tenue de route en virage, une opération de contrebraquage de la direction pour stopper la tendance du train arriere du véhicule à se maintenir en rotation lorsque le train avant a repris son alignement. This mode of suspension of the rear axle using an H-link chassis cannot, however, give the vehicle road holding qualities when cornering which are equivalent to those of rear suspensions with independent wheels as they H-frame deflections cause, when the vehicle fitted with this type of rear suspension, to turn when cornering, variations in drift which seriously affect the handling of the vehicle when it is requested when cornering. Variations in axle drift rear generally lead the vehicle to exhibit a oversteer behavior which requires on the part of the driver, when pushing the vehicle towards its limits for handling when cornering, a steering reverse operation to stop the tendency of the rear axle of the vehicle to remain in rotation when the nose gear has resumed its alignment.
La tendance survireuse provoquée par ce type de suspension s'explique par le fait que le châssis en H du train arrière vient s'orienter tangentiellement au cercle du virage au cours de celui-ci, ce qui réduit la dérive du train arrière. Par une sorte d'effet d'hystérésis mécanique, le châssis en
H ne -reçoit pas une sollicitation suffisante au moment de la remise en ligne du train avant du véhicule pour se réaligner sur ce train avant. Il faut donner une impulsion supplémentaire pour vaincre les frottement des articulations et ramener le chassis en H en position normale d'alignement et supprimer ainsi par un coup de volant de contrebraquage la tendance du véhicule à continuer le virage dans lequel il était engagé, après le réalignement du train avant pour sortir du virage.The oversteer trend caused by this type of suspension is explained by the fact that the H-frame of the rear axle is oriented tangentially to the circle of the turn during this, which reduces the drift of the rear axle. By a kind of mechanical hysteresis effect, the chassis
H does not receive sufficient stress when the front axle of the vehicle is brought back online to realign itself on this front axle. It is necessary to give an additional impulse to overcome the friction of the articulations and to bring back the chassis in H in normal position of alignment and thus to suppress by a blow of steering wheel of bracing the tendency of the vehicle to continue the turn in which it was engaged, after the realignment of the nose gear to exit the turn.
Les conducteurs des véhicules dotés d'une telle suspension n'apprécient guère la tendance survireuse du train arrière qui, bien qu'inoffensif dans les conditions usuelles de conduite, donne une impression d'insécurité. Drivers of vehicles fitted with such a suspension do not appreciate the oversteering tendency of the rear axle which, although harmless under normal driving conditions, gives an impression of insecurity.
L'un des buts de la présente invention est précisément de réaliser une articulation du châssis de liaison du train arrière du véhicule qui supprime les variations de dérive de ce train arrière et la tendance survireuse du véhicule tout en exigeant seulement des moyens de guidage pratiques et peu onéreux du type des articulations annulaires formant silent-bloc.One of the aims of the present invention is precisely to produce an articulation of the connection chassis of the rear axle of the vehicle which eliminates the variations in drift of this rear axle and the oversteer tendency of the vehicle while requiring only practical guidance means and inexpensive of the type of annular joints forming silent-block.
A cet effet, le dispositif d'articulation pour un train roulant tel que l'essieu arrière d'un véhicule automobile, du type dans lequel un bras support de roue est articulé en rotation sur un axe solidaire du chassis du véhicule par l'intermédiaire d'une liaison annulaire en matériau elas- tomère, interposee entre le bras support et l'axe, pour autoriser, d'une part, la- rotation limitée du bras support sous l'action de la suspension élastique du véhicule et, d'autre part, de légers débattements transversaux et axiaux du bras par rapport à l'axe solidaire du châssis sous l'action des forces transversales agissant axialement sur la roue et transmises au bras support, notamment lorsque le véhicule se déplace en virage, est caractérisé en ce que la liaison annulaire en matériau élastomère est munie de moyens de rigidification aptes à raidir cette liaison seulement dans l'un des sens d'application des forces axiales agissant sur le bras. To this end, the articulation device for a running gear such as the rear axle of a motor vehicle, of the type in which a wheel support arm is articulated in rotation on an axis secured to the chassis of the vehicle by means of of an annular connection made of elastomeric material, interposed between the support arm and the axis, to allow, on the one hand, the limited rotation of the support arm under the action of the elastic suspension of the vehicle and, on the other hand, slight transverse and axial deflections of the arm relative to the axis integral with the chassis under the action of transverse forces acting axially on the wheel and transmitted to the support arm, in particular when the vehicle is traveling in a bend, is characterized in that the annular connection of elastomeric material is provided with stiffening means capable of stiffening this connection only in one of the directions of application of the axial forces acting on the arm.
Les moyens de rigidification sont constitués de préférence par au moins un insert rigide qui est inclus dans la liaison annulaire pour augmenter la résistance à l'écrasement du matériau élastomère sous l'action des forces axiales de compression mais qui n'augmente. pratiquement pas la résistance de la liaison annulaire à l'action des forces de traction et des couples qui lui sont appliqués par le bras support. The stiffening means preferably consist of at least one rigid insert which is included in the annular connection to increase the resistance to crushing of the elastomeric material under the action of axial compressive forces but which does not increase. practically no resistance of the annular connection to the action of the tensile forces and the couples which are applied to it by the support arm.
Selon un autre mode de réalisation de l'invention, l'insert rigide est inclus uniquement dans une zone circonférencielle de la liaison annulaire pour autoriser le désaxage de cette liaison annulaire par rapport à l'axe solidaire du châssis sous l'action des couples exerces par le bras support sous l'effet des efforts transversaux exercés sur la roue. According to another embodiment of the invention, the rigid insert is included only in a circumferential zone of the annular connection to allow the offset of this annular connection relative to the axis integral with the chassis under the action of the couples exerted by the support arm under the effect of the transverse forces exerted on the wheel.
Dans la zone circonférencielle opposée à l'insert rigide, la liaison annulaire peut présenter des parties évidées pour augmenter son élasticité dans cette zone. L'insert rigide peut être placé, soit du coté du bras support de roue pour au-gmenter la résistance de la liaison annulaire à l'écrasement sous l'action des forces axiales de compression exercées par ce bras, soit du côté opposé au bras support de roue pour diminuer la résistance de la liaison annulaire à l'écrasement sous l'action des forces de compression exercées sur ce bras tout en s'opposant au déplacement axial du bras par rapport à l'axe solidaire du châssis. In the circumferential zone opposite the rigid insert, the annular connection may have recessed parts to increase its elasticity in this zone. The rigid insert can be placed either on the side of the wheel support arm to increase the resistance of the annular connection to crushing under the action of the axial compression forces exerted by this arm, or on the side opposite the arm wheel support to reduce the resistance of the annular connection to crushing under the action of the compressive forces exerted on this arm while opposing the axial displacement of the arm relative to the axis integral with the chassis.
Selon un mode de réalisation pratique de l'invention, l'insert rigide est une plaque noyée dans le matériau élastomère, cambrée sensiblement au rayon moyen de la liaison annulaire, dont le plan moyen est incliné par rapport à l'axe longitudinal de la liaison annulaire et dont le contour extérieur est sensiblement celui d'un secteur annulaire. La plaque est obtenue de préférence par découpe d'une tôle métallique telle qu'une tôle courante en acier et la partie la plus large du secteur annulaire est placée au voisinage de la périphérie intérieure ou exterieure de la liaison annulaire en élastomère qui enveloppe complètement la plaque et la protège ainsi de toute corrosion ou agression extérieure. According to a practical embodiment of the invention, the rigid insert is a plate embedded in the elastomeric material, arched substantially at the mean radius of the annular connection, the mean plane of which is inclined relative to the longitudinal axis of the connection annular and whose outer contour is substantially that of an annular sector. The plate is preferably obtained by cutting a metal sheet such as a standard steel sheet and the widest part of the annular sector is placed in the vicinity of the inner or outer periphery of the annular elastomer connection which completely envelops the plate and thus protects it from any corrosion or external attack.
La liaison annulaire et ses moyens de rigidification forment ainsi un bloc annulaire d'élastomère emprisonné entre deux éléments tubulaires rigides concentriques, l'un des bords de l'élément le plus intérieur étant rabattu vers l'extérieur pour maintenir latéralement la liaison annulaire tandis que l'un des bords de l'élément tubulaire le plus ex térieur est rabattu vers l'intérieur du côté opposé au bord rabattu de l'élément intérieur pour maintenir latéralement la liaison annulaire du côté opposé à celui maintenu par cet élément tubulaire intérieur. The annular connection and its stiffening means thus form an annular block of elastomer trapped between two concentric rigid tubular elements, one of the edges of the innermost element being folded outwards to laterally maintain the annular connection while one of the edges of the outermost tubular element is folded inwards on the side opposite the folded edge of the interior element to laterally maintain the annular connection on the side opposite to that held by this interior tubular element.

La Figure 5 est une représentation schêmatique des déplacements que subit le train arrière d'un véhicule équipé de bagues d'articulation selon l'invention lorsque le véhicule roule en virage. Figure 5 is a schematic representation of the movements undergone by the rear axle of a vehicle fitted with articulation rings according to the invention when the vehicle is traveling in a turn.
Si l'on se reporte à la Figure 1, on voit que le châssis 1 d'un véhicule est equipé d'un train arrière de type connu dans lequel un châssis en
H de liaison. 2 des roues 3 et 4 est constitué d'une poutre transversale 5 dotée de prolongements 6 et 7 qui constituent les branches courtes du H tandis que des bras 8 et 9 des roues 3 et 4 forment les branches longues du H.La liaison entre le châssis 1 du véhicule et le châssis en H 2 du train arrière est assurée par des axes 10 et 11 solidaires du châssis 1 et autour desquels sont articulés des paliers 12 et 13 ménagés dans les prolongements 6 et 7, par l'intermédiaire de blocs annulaires d'élastomère 14 et 15 constituant des sortes de "silent-blocs" qui autorisent des débattements d'amplitude limitée des paliers 12 et 13 dans toutes les directions en assurant un effort de rappel de ces paliers relativement à une position moyenne définie par rapport aux axes respectifs 10 et 11.If we refer to Figure 1, we see that the chassis 1 of a vehicle is equipped with a rear axle of known type in which a chassis in
H bond. 2 of the wheels 3 and 4 consists of a transverse beam 5 provided with extensions 6 and 7 which constitute the short branches of the H while arms 8 and 9 of the wheels 3 and 4 form the long branches of the H. The connection between the chassis 1 of the vehicle and the H-chassis 2 of the rear axle is provided by pins 10 and 11 integral with the chassis 1 and around which bearings 12 and 13 are articulated formed in the extensions 6 and 7, by means of annular blocks of elastomer 14 and 15 constituting kinds of "silent-blocks" which allow deflections of limited amplitude of the bearings 12 and 13 in all directions while ensuring an effort of return of these bearings relative to a defined average position relative to the respective axes 10 and 11.
La Figure 2 montre schématiquement les déplacements du train arriere sous l'action des forces de réaction transversales F1 et F2 transmises aux roues 3 et 4 lorsque le véhicule se déplace en virage. Les forces F, et F2 se transmettent aux paliers 12 et 13 où elles exercent sur les blocs d'elas- toméres 14 et 15 des efforts transversaux F, et F2 qui déplacent le centre du palier 12 de la position 12a à la position 12b décalée vers la droite de la Figure 2 d'une distance 12m et vers le bas sous l'effet du couple de basculement exercé sur le châssis 2 en H qui exerce sur ce bloc 14 un effor.t radial L1. Les efforts F', et F'2 et l'effort radial L2 produit par le couple de basculement exercé sur les bras 8 et 9 et le châssis 2, deplacent le centre du palier 13 de la position 13a à la position 13b vers la droite de la Figure 2 d'une distance 13m et vers le haut de la
Figure. La poutre transversale 5 vient ainsi se placer en travers par rapport à l'axe du véhicule en se décalant vers la droite de la figure par rapport au châssis I du véhicule, comme représenté en pointillés sur la Figure 2.Figure 2 schematically shows the movements of the rear axle under the action of the transverse reaction forces F1 and F2 transmitted to the wheels 3 and 4 when the vehicle is moving in a turn. The forces F, and F2 are transmitted to the bearings 12 and 13 where they exert on the elastomer blocks 14 and 15 transverse forces F, and F2 which move the center of the bearing 12 from the position 12a to the offset position 12b to the right of Figure 2 from a distance 12m and downwards under the effect of the tilting torque exerted on the chassis 2 at H which exerts on this block 14 a radial force L1. The forces F ', and F'2 and the radial force L2 produced by the tilting torque exerted on the arms 8 and 9 and the chassis 2, move the center of the bearing 13 from position 13a to position 13b to the right of Figure 2 from a distance 13m and up from the
Figure. The transverse beam 5 is thus placed crosswise relative to the axis of the vehicle by shifting to the right of the figure relative to the chassis I of the vehicle, as shown in dotted lines in FIG. 2.
A la suite du désaxage du châssis de liaison 2, un angle de dérive important 6 apparat sur le train arrière du véhicule qui tend à diminuer le rayon R de la trajectoire du virage (voir la Figure 1) et refuse de quitter cette trajectoire en virage lorsque le train avant du véhicule revient en ligne à la sortie du virage. Pour remettre le véhicule en ligne, le conducteur est oblige ,soit de relâcher la pression sur son volant de direction avant la sortie du virage, ce qui rend la trajectoire du véhicule imprécise, soit pour les virages pris rapidement et brutalement, de contrebraquer le train avant du véhicule, ce qui nuit gravement à l'agrément de conduite pour le conducteur moyen. Following the offset of the linkage chassis 2, a large drift angle 6 appears on the rear axle of the vehicle which tends to decrease the radius R of the trajectory of the turn (see Figure 1) and refuses to leave this trajectory when turning when the front axle of the vehicle comes back in line at the exit of the turn. To put the vehicle back in line, the driver is obliged either to release the pressure on his steering wheel before the exit from the turn, which makes the vehicle's trajectory imprecise, or for turns taken quickly and suddenly, to overturn the train front of the vehicle, which seriously affects driving pleasure for the average driver.
Pour remédier à ces défauts des dispositifs d'articulation connus, il faut s'opposer principalement au glissement latéral du châssis 2 du train arrière. Selon l'invention, la liaison annulaire en matériau élastomère qui est interposée entre chacun des paliers 12 ou 13 et son axe respectif 10 ou 11, est munie d'un insert rigide 16 constitué généralement d'une plaque de tôle noyée dans la masse des blocs d'élastomère 14 ou 15 et cambrée de préférence sensiblement au rayon moyen de l'anneau formé par ce bloc d'élastomère.L'insert 16 est logé dans le bloc d'élastomère 14 ou 15 selon un plan incliné pour constituer une sorte de bielle qui s'oppose au deplacementdu palier 12 ou 13 agissant en compression sur le bloc d'élastomère par l'intermédiaire d'un manchon extérieur annulaire 17 dont l'un des bords 18, celui de gauche sur la figure, est rabattu vers l'intérieur pour constituer une butée latérale pour le bloc d'élastomère. To remedy these shortcomings of known articulation devices, it is mainly necessary to oppose the lateral sliding of the chassis 2 of the rear axle. According to the invention, the annular connection made of elastomeric material which is interposed between each of the bearings 12 or 13 and its respective axis 10 or 11, is provided with a rigid insert 16 generally consisting of a sheet metal plate embedded in the mass of blocks of elastomer 14 or 15 and preferably arched substantially at the mean radius of the ring formed by this block of elastomer. The insert 16 is housed in the block of elastomer 14 or 15 according to an inclined plane to constitute a kind connecting rod which opposes the displacement of the bearing 12 or 13 acting in compression on the elastomer block by means of an annular outer sleeve 17 of which one of the edges 18, that of the left in the figure, is folded towards the inside to form a lateral stop for the elastomer block.
La liaison annulaire est montée sur l'axe 10 ou 11 solidaire du châssis 1 par l'intermédiaire d'un manchon annulaire intérieur 19 dont l'un des bords 20, du côté opposé au bord 18, est rabattu vers l'extérieur pour constituer une butée latérale pour le bloc d'élastomère.The annular connection is mounted on the axis 10 or 11 secured to the chassis 1 by means of an inner annular sleeve 19 of which one of the edges 20, on the side opposite the edge 18, is folded outwards to constitute a lateral stop for the elastomer block.
Dans la zone circonférencielle du bloc d'élastomère qui est opposée à l'insert 16, sont prévus des évidements 21 et 22 qui augmentent l'elas- ticité de cette zone. On voit sur la Figure 4 que l'insert 16 noyé dans le bloc d'élastomère, présente un contour extérieur en forme de secteur annulaire dont les angles sont arrondis pour éviter de déchirer intérieurement l'élastomère 14 ou 15 qui est acherise aux anchons 17 et 19 et a l'insert 16. In the circumferential zone of the elastomer block which is opposite to the insert 16, recesses 21 and 22 are provided which increase the smoothness of this zone. We see in Figure 4 that the insert 16 embedded in the elastomer block, has an outer contour in the form of an annular sector whose corners are rounded to avoid tearing the elastomer 14 or 15 internally which is anchored to anchors 17 and 19 and insert 16.
Le fonctionnement d'un train arrière de véhicule équipe d'articulations selon l'invention est illustré schématiquement sur la Figure 5. The operation of a rear axle of a vehicle fitted with articulations according to the invention is illustrated diagrammatically in FIG. 5.
On voit que l'insert 16 s'oppose au déplacement axial du châssis 2 agissant sur lui en compressionmais-peut, par contre, pivoter pour autoriser le déplacement du centre 12a du palier 12 en 12c sensiblement selon une direction radiale sous l'action des forces radiales produites par le couple agissant sur le châssis 2 du train arrière. De mime, le centre 13a du palier 13 se déplace en 13c vers le bas de la figure par suite du pivotement de l'insert 16 sous l'action de l'effort transversal F'2.We see that the insert 16 opposes the axial displacement of the chassis 2 acting on it in compression but can, on the other hand, pivot to allow the displacement of the center 12a of the bearing 12 at 12c substantially in a radial direction under the action of the radial forces produced by the torque acting on the chassis 2 of the rear axle. Similarly, the center 13a of the bearing 13 moves at 13c towards the bottom of the figure as a result of the pivoting of the insert 16 under the action of the transverse force F'2.
Le déplacement du châssis 2 représenté en tirets et son désaxage sont
beaucoup plus faibles ainsi que l'angle de dérive 6 qui ne varie que très
peu au cours du déroulement d'un virage. Le véhicule ne donne plus au con
ducteur l'impression de "s'enrouler autour des virages" et produit une
impression de sécurité' beaucoup plus grande.The displacement of the chassis 2 shown in dashes and its offset are
much smaller as well as the drift angle 6 which varies only very
little during the course of a turn. The vehicle no longer gives con
conductor the impression of "wrapping itself around the bends" and produces a
much greater sense of security.
Bien entendu, la présente invention n'est nullement limitée aux modes
de réalisation décrits et représentés; elle est susceptible de nombreuses
variantes accessibles à l'homme de l'art, suivant les applications envisa
gées et sans que l'on ne s'écarte de l'esprit de l'invention.Of course, the present invention is in no way limited to the modes
of embodiment described and represented; she is likely to many
variants accessible to those skilled in the art, depending on the applications envisaged
without departing from the spirit of the invention.
Elle vise en particulier toutes les liaisons annulaires en matériau élas
tomère qui comportent un insert rigide noyé dans la masse d'élastomère
uniquement dans une zone circonférencielle de cette masse et qui peut présenter
la fome d'une plaque dont le plan moyen est incliné par rapport à l'axe
longitudinal de la liaison annulaire et dont le contour extérieur est sensiblement celui d'un secteur annulaire dont les arêtes ont été arrondies.It targets in particular all annular connections made of elas material
tomers which have a rigid insert embedded in the mass of elastomer
only in a circumferential zone of this mass and which can present
the form of a plate whose mean plane is inclined relative to the axis
longitudinal of the annular connection and whose outer contour is substantially that of an annular sector whose edges have been rounded.
On doit comprendre éqalement qu'il est possible de doter un seul des
paliers 12 ou 13 d'une articulation en matériau élastomère comportant un
insert rigide 16 selon l'invention, cet. unique insert suffisant pour s'oppo
ser au deplacement axial du chassis de liaison 2. We must also understand that it is possible to endow only one of the
bearings 12 or 13 of a hinge of elastomeric material comprising a
rigid insert 16 according to the invention, this. single insert sufficient to oppose
use the axial displacement of the connecting frame 2.
