Description
La présente invention concerne un dispositif de stabilisation en roulis pour suspension de véhicule, qui est associé au moins à un essieu dudit véhicule. The present invention relates to a roll stabilization device for vehicle suspension, which is associated with at least one axle of said vehicle.
Dans les véhicules, notamment les véhicules utilitaires, le flottement en roulis de la suspension, conditionné par la conception du véhicule, est fonction du poids à vide et du poids en charge, ainsi que de la répartition de la charge utile transportée. Dans des conditions déterminées de marche, ce flottement en roulis de la suspension peut alors atteindre des valeurs si élevées qu'on doit prendre des mesures incompatibles avec le confort de marche, ou bien par exemple, dans le cas d'engins de travail transportés, la précision de guidage des engins en position de travail est rendue très difficile ou même impossible à obtenir. In vehicles, in particular commercial vehicles, the roll floating of the suspension, conditioned by the design of the vehicle, is a function of the unladen weight and the laden weight, as well as the distribution of the payload transported. Under determined conditions of operation, this rolling floating of the suspension can then reach such high values that measures must be taken which are incompatible with walking comfort, or else for example in the case of transported working machines, the precision of guiding the machines in the working position is made very difficult or even impossible to obtain.
Des dispositifs connus, comme notamment des stabilisateurs transversaux classiques, sont pourvus d'une raideur anti-flottement qui est fixe, ou variable seulement dans des limites étroites, mais ils ne conviennent cependant en aucun cas pour éliminer complètement le flottement de suspension. Known devices, such as in particular conventional transverse stabilizers, are provided with an anti-floating stiffness which is fixed, or variable only within narrow limits, but they are however in no case suitable for completely eliminating the floating of suspension.
D'autres dispositifs connus agissent, en même temps que sur le flottement de la suspension, d'une manière indésirable obligatoirement aussi sur la suspension verticale de la caisse du véhicule. Other known devices act, at the same time as on the floating of the suspension, in an undesirable manner necessarily also on the vertical suspension of the vehicle body.
L'invention a pour but d'agencer un dispositif de stabilisation en roulis pour suspension permettant que le mouvement de flottement puisse être limité ou même exclu, de façon prédéterminée, sans influencer nécessairement la suspension verticale de la caisse du véhicule, et sans que les possibilités d'utilisation du véhicule, comme notamment la garde au sol ou l'angle d'inclinaison, soient affectées. The object of the invention is to arrange a roll stabilization device for suspension allowing the floating movement to be limited or even excluded, in a predetermined manner, without necessarily influencing the vertical suspension of the vehicle body, and without the possibilities for using the vehicle, such as ground clearance or angle of inclination, are affected.
Ce problème est résolu selon l'invention en ce que le dispositif de stabilisation est agencé sous forme d'un châssis de torsion présentant une rigidité à la torsion qui peut varier jusqu'au blocage du flottement de la suspension, et relié de façon articulée par au moins deux points avec le châssis du véhicule, et au moins deux autres points avec essieu du véhicule. This problem is solved according to the invention in that the stabilization device is arranged in the form of a torsion frame having a torsional rigidity which can vary until the floating of the suspension is blocked, and connected in an articulated manner by at least two points with the vehicle chassis, and at least two other points with the vehicle axle.
Selon d'autres particularités de l'invention - le châssis de torsion est relié à l'essieu de véhicule
et/ou au châssis de véhicule par au moins deux bras en
forme de leviers - pour mettre en service ou hors service le châssis de
torsion, un ou plusieurs points de liaison sont agencés
de façon séparable - un ou plusieurs éléments du châssis de torsion, par
exemple les bras en forme de leviers, sont agencés comme
des ressorts et/ou des amortisseurs de caractéristique
variable jusque dans une condition de blocage - il est prévu un ensemble additionnel constitué par un
ou plusieurs éléments formant ressorts et/ou amortis
seurs de caractéristique variable, pour agir addition
nellement sur la suspension verticale du châssis de
véhicule jusqu'au blocage.According to other features of the invention - the torsion frame is connected to the vehicle axle
and / or to the vehicle chassis by at least two arms in
lever shape - to activate or deactivate the chassis
twist, one or more connecting points are arranged
separable - one or more elements of the torsion frame, for
example the arms in the form of levers, are arranged as
characteristic springs and / or dampers
variable up to a blocking condition - an additional assembly is provided, consisting of a
or more elements forming springs and / or damped
sors of variable characteristic, to act addition
on the vertical suspension of the chassis
vehicle until blocked.
L'invention concerne également un véhicule comportant au moins un essieu suspendu verticalement et un dispositif additionnel de stabilisation qui comporte deux liaisons articulées placées du côté du châssis de véhicule et deux liaisons articulées placées du côté de l'essieu, le véhicule étant caractérisé en ce que le dispositif de stabilisation est essentiellement constitué par un châssis de torsion qui est rigide à la torsion, que les liaisons articulées sont constituées du côté du châssis de véhicule et/ou du côté de l'essieu par des organes de suspension, et en ce que, parmi lesdites liaisons articulées, au minimum l'une d'entre elles est au moins partiellement séparable en vue d'une mise en service ou hors service du châssis de torsion. The invention also relates to a vehicle comprising at least one vertically suspended axle and an additional stabilization device which comprises two articulated connections placed on the side of the vehicle chassis and two articulated connections placed on the side of the axle, the vehicle being characterized in that the stabilization device is essentially constituted by a torsion frame which is torsionally rigid, that the articulated connections are formed on the side of the vehicle frame and / or on the axle side by suspension members, and in this that, among said articulated connections, at least one of them is at least partially separable for the purpose of putting the torsion frame into service or out of service.
Du fait de la possibilité qui est donnée d'agir de façon indépendante soit sur le flottement de la suspension soit sur la suspension verticale de caisse, il est possible de passer d'un état dans lequel absolument aucune influence n'est exercée sur la suspension, jusqu'à un blocage total ; tous les états intermédiaires, y compris des états variables, peuvent être obtenus pour les différents essieux. Because of the possibility which is given to act independently either on the floating of the suspension or on the vertical suspension of body, it is possible to pass from a state in which absolutely no influence is exerted on the suspension , until a total blockage; all intermediate states, including variable states, can be obtained for the different axles.
D'autres caractéristiques et avantages de l'invention seront mis en évidence dans la suite de la description donnée à titre d'exemple non limitatif et les dessins annexés dans lesquels, pour simplifier, les exemples de réalisation sont schématisés en avant de l'essieu avant d'un véhicule, mais il est à noter qu'il est possible de les adapter d'une manière en principe identique également pour tous les autres essieux du véhicule, et notamment aussi bien en avant qu'en arrière d'un essieu du véhicule ; sur les dessins, les figures 1 à 8 représentent schématiquement le principe fondamental de l'invention, selon des modes de réalisation préférentiels présentés à titre d'exemples. Other characteristics and advantages of the invention will be highlighted in the following description given by way of nonlimiting example and the appended drawings in which, for simplicity, the exemplary embodiments are shown diagrammatically in front of the axle. front of a vehicle, but it should be noted that it is possible to adapt them in a manner which is in principle identical also for all the other axles of the vehicle, and in particular both in front of and behind an axle of the vehicle; in the drawings, FIGS. 1 to 8 schematically represent the fundamental principle of the invention, according to preferred embodiments presented by way of examples.
Tel qu'illustre sur les figures 1 et 2, le dispositif de l'invention se compose d'un châssis de torsion 1 comportant un corps de torsion 2 et des bras de liaison 3, 4, ce châssis étant pourvu d'une résistance à la torsion réglable, ou bien étant réalisé avec rigidité constante anti-torsion. Le châssis de torsion 1 est ici relié en deux points 5, de façon articulée, avec des éléments 8 fixés rigidement sur le châssis 6 du véhicule 7 (le châssis pourrait aussi etre relié directement au châssis du véhicule), et il est relié en deux autres points 9, également de façon articulée, avec un essieu 10 du véhicule.En fonction de la valeur de la rigidité à la torsion choisie pour le châssis de torsion 1, le châssis 6 du véhicule exécute, sous l'effet des forces parasites extérieures, un mouvement de flottement qui peut être contrôlé de manière prédéterminée ; lorsque le châssis de torsion 1 est réalisé avec une rigidité constante anti-torsion -, le mouvement de flottement est complètement exclu grâce à l'invention, tandis que la suspension verticale de caisse de véhicule reste non influencée. Le châssis de torsion 1 peut alors également assurer le guidage cinématique de l'essieu 10 du véhicule. As illustrated in FIGS. 1 and 2, the device of the invention consists of a torsion frame 1 comprising a torsion body 2 and link arms 3, 4, this frame being provided with a resistance to the adjustable torsion, or else being made with constant anti-torsion rigidity. The torsion chassis 1 is here connected at two points 5, in an articulated manner, with elements 8 rigidly fixed to the chassis 6 of the vehicle 7 (the chassis could also be connected directly to the chassis of the vehicle), and it is connected in two other points 9, also articulated, with an axle 10 of the vehicle. Depending on the value of the torsional rigidity chosen for the torsion frame 1, the frame 6 of the vehicle performs, under the effect of external parasitic forces , a floating movement which can be controlled in a predetermined manner; when the torsion frame 1 is produced with constant anti-torsion stiffness -, the floating movement is completely excluded thanks to the invention, while the vertical suspension of the vehicle body remains unaffected. The torsion frame 1 can then also provide kinematic guidance for the axle 10 of the vehicle.
Conformément à la variante illustrée à la figure 3, le châssis de torsion 1 est monté sur le châssis de véhicule 6 à l'aide de biellettes d'articulation 11. Le guidage cinématique de l'essieu est assuré dans ce cas par des organes classiques de guidage, aussi bien existants que montés ultérieurement sur des véhicules finis dans le cas d'une adaptation du dispositif à ceux-ci. Les biellettes 11 pourraient aussi être disposées entre le châssis de torsion 1 et essieu 10 du véhicule. In accordance with the variant illustrated in FIG. 3, the torsion frame 1 is mounted on the vehicle frame 6 by means of articulation links 11. The kinematic guidance of the axle is in this case provided by conventional members guide, both existing and subsequently mounted on finished vehicles in the case of an adaptation of the device to these. The links 11 could also be arranged between the torsion frame 1 and axle 10 of the vehicle.
La figure 4 illustre le montage d'éléments de longueur variable 12 entre le châssis de torsion 1 et le châssis 6 du véhicule, pour agir sur la rigidité à la torsion. Ces éléments 12 peuvent être disposés en un ou plusieurs points de liaison, et se composer d'un ressort, ou d'un amortisseur, ou encore d'un ressort et d'un amortisseur, avec des caractéristiques pouvant être prédéterminées. Le système de suspension ou d'amortissement peut dans ce cas être constitué par des moyens hydrauliques, pneumatiques, mécaniques, ou électromagnétiques. FIG. 4 illustrates the mounting of elements of variable length 12 between the torsion chassis 1 and the chassis 6 of the vehicle, to act on the torsional rigidity. These elements 12 can be arranged at one or more connection points, and consist of a spring, or a shock absorber, or even a spring and a shock absorber, with characteristics that can be predetermined. The suspension or damping system can in this case be constituted by hydraulic, pneumatic, mechanical, or electromagnetic means.
En fonction de la caractéristique choisie pour l'élément variable 12, il est possible d'agir sur le flottement de la suspension et/ou sur l'amortissement du flottement du châssis 6, depuis une absence d'action jusqu'à un blocage. Les éléments variables 12 peuvent être agencés de manière à pouvoir être mis en service, hors service, ou bien manoeuvrés à partir de la place du conducteur. Depending on the characteristic chosen for the variable element 12, it is possible to act on the floating of the suspension and / or on the damping of the floating of the chassis 6, from an absence of action to a blockage. The variable elements 12 can be arranged so that they can be put into service, out of service, or else operated from the driver's seat.
Pour agir additionnellement sur la suspension verticale du châssis de véhicule 6, il est prévu, conformément à la variante illustrée à la figure 5, un ou plusieurs ressorts ou amortisseurs, ou bien des éléments formant ressorts et amortisseurs 13 entre le châssis 6 du véhicule et le corps de torsion 2, de sorte que ces éléments peuvent assister ou même aussi remplacer le système de suspension verticale ou d'amortissement du châssis du véhicule ; la caractéristique de ces éléments peut varier jusqu'au blocage. En même temps que le blocage en roulis de la suspension, il est possible d'assurer ainsi un guidage rigide de l'essieu qui est avantageux pour des conditions déterminées de travail. To act additionally on the vertical suspension of the vehicle chassis 6, there is provided, in accordance with the variant illustrated in FIG. 5, one or more springs or dampers, or else elements forming springs and dampers 13 between the chassis 6 of the vehicle and the torsion body 2, so that these elements can assist or even also replace the vertical suspension or damping system of the vehicle chassis; the characteristic of these elements can vary until blocking. At the same time as the roll locking of the suspension, it is thus possible to ensure rigid guidance of the axle which is advantageous for specific working conditions.
Sur la figure 6, on a illustré la possibilité de désaccoupler les bras de liaison 3. Le verrouillage et lue déverrouillage peuvent être réalisés par différents moyens, par exemple mécaniquement à l'aide d'un levier 14, ou bien hydrauliquement, pneumatiquement, électriquement ou électromagnétiquement. In FIG. 6, the possibility of uncoupling the link arms 3 has been illustrated. The locking and unlocking can be carried out by different means, for example mechanically using a lever 14, or hydraulically, pneumatically, electrically or electromagnetically.
Sur la figure 7, on a illustré une possibilité de conférer au corps de torsion 2 une rigidité à la torsion variable, pouvant être prédéterminée. In Figure 7, there is illustrated a possibility of giving the torsion body 2 a variable torsional stiffness, which can be predetermined.
Les deux moitiés 2a, 2b du corps de torsion divisé 2 sont appliquées l'une contre l'autre par l'intermédiaire d'un ressort réglable 15, le moment résistant de torsion désiré étant obtenu au moyen d'une garniture de friction 16. Le mode d'actionnement et le comportement à la torsion peuvent être, également dans ce cas, modifiés par des différents moyens additionnels, tels que ceux déjà cités en référence à la figure 4. La position de flottement
du véhicule nécessaire en cas de besoin (condition neutre
ou désaccouplée) peut être obtenue par exemple par un élé
ment additionnel correspondant à une forme homologue.The two halves 2a, 2b of the divided torsion body 2 are applied against each other by means of an adjustable spring 15, the desired torsional resistance moment being obtained by means of a friction lining 16. The actuation mode and the torsional behavior can be, also in this case, modified by various additional means, such as those already cited with reference to FIG. 4. The floating position
of the vehicle required if necessary (neutral condition
or uncoupled) can be obtained for example by an element
additional ment corresponding to a homologous form.
Le dispositif est conçu de manière que, en cas de
besoin, par exemple pour des travaux d'entretien ou bien
en cas de non-utilisation, il puisse être désactivé d'une
manière simple, ou bien enlevé avec de faibles frais de
démontage, sans que la suspension et l'amortissement de
suspension du véhicule soient modifiés. En outre il doit
pouvoir être facilement monté sur une structure existante.The device is designed so that, in the event of
need, for example for maintenance work or
in case of non-use, it can be deactivated
simple way, or removed with low cost of
disassembly, without the suspension and damping of
vehicle suspension be modified. In addition, he must
be able to be easily mounted on an existing structure.
Le châssis de torsion 1 peut en outre présenter
une structure différente de celle illustrée à la figure 2,
et être choisi d'une part en fonction du degré recherché
de résistance à la torsion, et d'autre part selon le type
de véhicule concerné, pour des questions d'encombrement, d'accessibilité, de facilité d'entretien. La figure 8 il
lustre ainsi à titre d'exemple trois variantes de châssis de torsion 1.The torsion frame 1 can also have
a structure different from that illustrated in FIG. 2,
and be chosen on the one hand according to the degree sought
torsional strength, and secondly depending on the type
vehicle concerned, for reasons of space, accessibility, ease of maintenance. Figure 8 il
For example, three chandeliers of the torsion frame 1 are glossed.
Ainsi, selon un mode particulièrement avantageux de mise en oeuvre de l'invention, un véhicule comportant
au moins un essieu suspendu verticalement est pourvu d'un dispositif de stabilisation additionnel, qui comporte deux
liaisons articulées placées du côté du châssis, et deux
liaisons articulées placées du côté de l'essieu, le dispo
sitif de stabilisation étant essentiellement constitué par un châssis de torsion rigide à la torsion, et les liaisons
articulées sont constituées, du côté du châssis de véhicule et/ou du côté de l'essieu, par des organes de suspension,
au minimum une desdites liaisons étant au moins partiellement séparable pour la mise en service ou hors service du
châssis de torsion. Une possibilité de séparation, correspondant complètement ou partiellement à une possibilité de
séparation mécanique, c'est-à-dire la suppression d'une
liaison articulée, peut par exemple être obtenue au y d'un organe de manoeuvre fonctionnant hydrauliqwsent, comme notmBnt un amortis-
seur avant une caractéristique Cowant être sélsctionnée, e, c'est--SX=e réglable. Thus, according to a particularly advantageous embodiment of the invention, a vehicle comprising
at least one axle suspended vertically is provided with an additional stabilization device, which comprises two
articulated links placed on the chassis side, and two
articulated connections placed on the axle side, the dispo
stabilization device consisting essentially of a torsion frame which is rigid in torsion, and the connections
articulated are formed, on the side of the vehicle chassis and / or on the axle side, by suspension members,
at least one of said links being at least partially separable for putting the service into or out of service
torsion frame. A possibility of separation, corresponding completely or partially to a possibility of
mechanical separation, i.e. the removal of a
articulated connection, can for example be obtained at the y of an operating member operating hydrauliqwsent, as notmBnt a damping
sor before a Cowant characteristic to be selected, e is - SX = e adjustable.
