Description

"Dispositif de transport par câble muni de moyens d'amortissement " "Cable transport device with damping means"
La présente invention concerne un dispositif de transport par câble muni de moyens d'amortissement de chocs.The present invention relates to a cable transport device provided with shock absorbing means.
Elle trouve son application pour tout type de dispositifs de transport à câble dont les véhicules sont roulants ou suspendus tels que des téléphériques, télécabines, télésièges, à voyageurs ou à matériaux. On connaît des i nstal lations de transport de person nes ou de marchandises comme les téléphériques ou les télécabines utilisés notamment dans les stations de sports d'hiver.It finds its application for all types of cable transport devices whose vehicles are rolling or suspended such as cable cars, gondola lifts, chairlifts, passenger or material. There are known ways of transporting people or goods such as cable cars or gondolas used especially in winter sports resorts.
Avec ce type d'installation, les véhicules ont une vitesse importante de 6 àWith this type of installation, vehicles have a speed of 6 to
10 mètres par seconde. Ainsi, les véhicules sont soumis à des oscillations importantes, notamment longitudinales, lors des passages en gare et/ou lors du passage au niveau de pylônes de maintien de câbles. Ce phénomène est produit par des accélérations, décélérations, des dysfonctionnements ou des freinages d'urgence. Il peut être amplifié ou même généré par du vent et notamment des vents longitudinaux.10 meters per second. Thus, the vehicles are subject to significant oscillations, including longitudinal, during passages in the station and / or when passing at the level of towers cable retention. This phenomenon is produced by accelerations, decelerations, malfunctions or emergency braking. It can be amplified or even generated by wind and especially longitudinal winds.
Le risque principal d'une telle installation réside dans le fait que le véhicule peut entrer en contact avec des structures fixes environnantes.The main risk of such an installation lies in the fact that the vehicle can come into contact with surrounding fixed structures.
En effet, avec les installations classiques, un choc peut générer des accidents corporels aux passagers ou provoquer des dégâts matériels importants.Indeed, with conventional installations, a shock can generate bodily injury to passengers or cause significant material damage.
Il existe donc le besoin de proposer un dispositif de transport par câble dont la sécurité des passagers est améliorée et les risques de détérioration sont diminués.There is therefore a need to provide a cable transportation device that improves passenger safety and reduces the risk of deterioration.
A cet effet, la présente invention comprend des moyens d'amortissement disposés sur le véhicule de transport.For this purpose, the present invention comprises damping means arranged on the transport vehicle.
Ainsi, lorsque le véhicule oscille et rentre en contact avec des obstacles alentours, les chocs sont amortis par les moyens d'amortissement. Les personnes éventuellement transportées ne ressentent que faiblement les chocs et les risques de détérioration du véhicule et des obstacles alentours sont très nettement réduits.Thus, when the vehicle oscillates and comes into contact with surrounding obstacles, the shocks are damped by the damping means. People who are transported may only feel a little shock and the risk of deterioration of the vehicle and obstacles around are very much reduced.
Préférentiellement, les moyens d'amortissement comportent un moyen déformable élastiquement et/ou un moyen déformable plastiquement de sorte à absorber l'onde de choc.Preferably, the damping means comprise an elastically deformable means and / or plastically deformable means so as to absorb the shock wave.
De plus, le dispositif comprend, selon un mode de réalisation, des moyens d'amortissement additionnels au niveau de structures fixes du dispositif qui peuvent constituer des obstacles sur le parcours du véhicule. Ces structures fixes sont à titre d'exemple, les gares d'arrivée, de départ, intermédiaires, les pylônes de maintien du câble etc. En ayant des moyens d'amortissement et des moyens d'amortissement additionnels avantageusement aptes à coopérer lors de chocs, les ondes de choc sont encore mieux amorties et les structures fixes et véhicules sont protégés. D'autres buts et avantages apparaîtront au cours de la description qui suit d'un mode préféré de réalisation de l'invention qui n'en est cependant pas limitatif. La présente invention concerne un dispositif de transport par câble comprenant au moins un véhicule suspendu à au moins un câble caractérisé par le fait qu'au moins un véhicule est muni de moyens d'amortissement des chocs avec des obstacles constitués par des structures fixes. Selon des variantes préférées de l'invention mais non limitatives, le dispositif est tel que :In addition, the device comprises, according to one embodiment, additional damping means at fixed structures of the device which may constitute obstacles on the path of the vehicle. These fixed structures are, for example, arrival, departure and intermediate stations, cable retention towers, etc. By having damping means and additional damping means advantageously able to cooperate during shocks, the shock waves are even better damped and the fixed structures and vehicles are protected.

La présente invention concerne un dispositif de transport comprenant au moins un véhicule 1 suspendu de manière fixe à au moins un câble tracteur par des moyens d'attache du type pinces ou bien par des moyens de roulement de sorte que le véhicule est roulant sur au moins un câble. Le terme suspendu comprend ces différents modes de réalisation.The present invention relates to a transport device comprising at least one vehicle 1 fixedly suspended from at least one towing cable by fastening means of the clamp type or by rolling means so that the vehicle is rolling on at least a cable. The term suspended includes these various embodiments.
Les figures et la description présentent un dispositif muni d'un seul véhicule 1. Bien entendu, le dispositif selon l'invention peut comprendre une pluralité de véhicules 1. Le véhicule 1 peut être du type cabine de téléphérique ou siège de télésiège ou autre.The figures and the description show a device equipped with a single vehicle 1. Of course, the device according to the invention may comprise a plurality of vehicles 1. The vehicle 1 may be of the cable car cabin type or chairlift seat or the like.
Le véhicule 1 comprend des moyens d'amortissement 2 des chocs. Ces moyens d'amortissement 2 sont destinés à amortir les chocs lors de contacts entre le véhicule 1 et les éventuelles structures fixes 5 disposées aux alentours du véhicule 1 ou avec d'autres véhicules du dispositif. Ces moyens d'amortissement 2 permettent donc aux passagers ou aux marchandises transportées de ne pas subir les conséquences des chocs.The vehicle 1 comprises damping means 2 shocks. These damping means 2 are intended to dampen shocks during contact between the vehicle 1 and any fixed structures 5 arranged in the vicinity vehicle 1 or with other vehicles of the device. These damping means 2 therefore allow the passengers or goods carried not to suffer the consequences of shocks.
On entend par structures fixes 5, ou bien encore obstacles alentours, des structures qui sont fixes relativement au déplacement d'au moins un véhicule 1 . A titre d'exemple, gares d'arrivée, de départ, intermédiaire, pylônes de maintien du câble. Ainsi, structure fixe ne comprend pas les moyens de su spen tes d u véh i cu l e 1 . Les moyens d'amortissement 2 sont préférentiellement disposés au niveau d'au moins une paroi latérale 3 du véhicule 1 . On entend par parois latérales, les parois du véhicule 1 orientées se n s i bl em ent d a n s l a d i rect ion d e d épl ace m ent d u véh i cu l e 1 . Préférentiellement, les moyens d'amortissement 2 sont au moins disposés sur la paroi latérale 3 du véhicule 1 au regard des structures fixes 5.Fixed structures 5, or even surrounding obstacles, are structures that are fixed relative to the movement of at least one vehicle 1. For example, arrival, departure and intermediate stations, cable retention towers. Thus, a fixed structure does not include the means of supernatants of the vehicle. The damping means 2 are preferably arranged at the level of at least one side wall 3 of the vehicle 1. Side walls are understood to mean the walls of the vehicle 1 facing away from each other while the vehicle is moving. Preferably, the damping means 2 are at least arranged on the side wall 3 of the vehicle 1 with respect to the fixed structures 5.
Les moyens d'amortissement 2 sont disposés préférentiellement selon une direction longitudinale correspondant à la direction de déplacement du véhicule 1 comme représenté en figure 1.The damping means 2 are preferably arranged in a longitudinal direction corresponding to the direction of movement of the vehicle 1 as shown in FIG.
Selon un premier mode de réalisation, les moyens d'amortissement 2 peuvent en outre être disposés sur les autres parois du véhicule 1 de sorte à amortir également d'autres chocs. Comme représenté en figure 2, les moyens d'amortissement 2 sont situés sur les angles formés par l'intersection du toit et des parois verticales de la cabine du véhicule 1.According to a first embodiment, the damping means 2 may further be arranged on the other walls of the vehicle 1 so as to also dampen other shocks. As represented in FIG. 2, the damping means 2 are situated on the angles formed by the intersection of the roof and the vertical walls of the cabin of the vehicle 1.
Selon un premier mode de réalisation, les moyens d'amortissement 2 comportent un moyen déformable élastiquement. Selon une première possibilité, le moyen déformable élastiquement comprend au moins un matériau déformable élastiquement. En effet, ce type de matériau permet d'absorber l'énergie générée par l'onde de choc par sa déformation élastique. A titre d'exemple, on utilisera comme matériau des élastomères du type caoutchoucs, silicones, polyuréthanes. Selon une deuxième possibilité, le moyen déformable élastiquement comprend une structure déformable élastiquement. A titre d'exemple, on utilisera une structure en ressort ou comme décrit ci-après un bourrelet hémicyclique creux. Selon une variante, une structure déformable élastiquement peut être combinée à au moins un matériau déformable élastiquement.According to a first embodiment, the damping means 2 comprise an elastically deformable means. According to a first possibility, the elastically deformable means comprises at least one elastically deformable material. Indeed, this type of material absorbs the energy generated by the shock wave by its elastic deformation. By way of example, elastomers of the rubber, silicone and polyurethane type will be used as the material. According to a second possibility, the elastically deformable means comprises an elastically deformable structure. By way of example, use will be made of a spring structure or as described below a hollow hemicyclic bead. According to one variant, an elastically deformable structure may be combined with at least one elastically deformable material.
La structure peut comprendre un système à ressorts, notamment à ressorts de compression, des amortisseurs à gaz... On entend par déformable élastiquement, une déformation réversible.The structure may comprise a spring system, in particular with compression springs, gas dampers, etc. Elastically deformable means a reversible deformation.
Selon un deuxième mode de réalisation, les moyens d'amortissement 2 comportent un moyen déformable plastiquement. Selon une première possibilité, le moyen déformable plastiquement comprend au moins un matériau déformable plastiquement. Selon une deuxième possibilité, le moyen déformable plastiquement comprend un structure déformable plastiquement. Ce type de matériau ou de structure absorbe l'énergie générée par un choc en se déformant de manière irréversible.According to a second embodiment, the damping means 2 comprise a plastically deformable means. According to a first possibility, the plastically deformable means comprises at least one plastically deformable material. According to a second possibility, the plastically deformable means comprises a plastically deformable structure. This type of material or structure absorbs the energy generated by a shock by deforming irreversibly.
Des exemples de structure consistent en :Examples of structure consist of:
- un organe déformable par écrasement (du type soufflet) en cas de compression,a deformable member by crushing (of the bellows type) in the event of compression,
- une structure tubulaire métallique déformable plastiquement par flexion,a metal tubular structure that is deformable plastically by bending,
- des blocs en plastique creux déformables plastiquement par éclatement.hollow plastic blocks which are plastically deformable by bursting.
Selon une possibilité, une structure déformable plastiquement peut être combinée à au moins un matériau déformable plastiquement. Les moyens d'amortissement 2 sont préférentiellement de la forme d'un bourrelet hémicyclique, d'autre formes du type parallélépipédique ou autres peuvent être prévues. Les moyens d'amortissement 2 du type bourrelet présentent au choix une structure pleine ou creuse.According to one possibility, a plastically deformable structure can be combined with at least one plastically deformable material. The damping means 2 are preferably in the form of a hemyclic bead, other forms of the parallelepiped type or others may be provided. The damping means 2 of the bead type optionally have a solid or hollow structure.
De sorte à être efficaces, les moyens d'amortissement 2 sont de forme convexe. La surface extérieure des moyens d'amortissement 2 est à titre d'exemple soit curviligne, soit formée de segments rectilignes successifs tel que représenté en figure 1. Cette dernière variante présente l'avantage d'avoir une surface d'appui éventuelle lors de chocs contre les structures fixes 5 qui soit plus importante que lorsque la surface extérieure est curviligne. Cette plus grande surface d'appui entre les moyens d'amortissement 2 et les structures fixes 5 permet une meilleure répartition des forces d'appui et donc un meilleur amortissement de l'onde de choc. De plus, la structure des moyens d'amortissement 2 selon le mode de réalisation où la surface extérieure est formée d'une pluralité de segments rectilignes successifs confère une certaine rigidité nécessaire pour ne pas que les moyens d'amortissement 2 se déforment de manière excessive lors de chocs ou contacts peu violents.In order to be effective, the damping means 2 are of convex shape. The outer surface of the damping means 2 is, for example, curvilinear or formed of successive rectilinear segments as shown in FIG. 1. This latter variant has the advantage of having a possible bearing surface during impacts. against fixed structures 5 which is larger than when the outer surface is curvilinear. This greater support surface between the damping means 2 and the fixed structures 5 allows a better distribution of the support forces and therefore better damping of the shock wave. In addition, the structure of the damping means 2 according to the embodiment where the outer surface is formed of a plurality of successive rectilinear segments provides a certain rigidity necessary not that the damping means 2 deform excessively. during shocks or mild contact.
Selon une autre possibilité, les moyens d'amortissement 2 comprennent un élément rigide monté sur des amortisseurs 8. On peut prévoir à titre d'exemple un élément du type d'une plaque avantageusement rigide montée sur des amortisseurs. Les amortisseurs permettent d'absorber l'énergie des chocs. Les amortisseurs sont à titre d'exemple des vérins à gaz, hydrauliques, pneumatiques ou bien des ressorts ou un élément en matériau déformable élastiquement comme les élastomères cités ci-dessus.According to another possibility, the damping means 2 comprise a rigid element mounted on the dampers 8. It is possible to provide for example an element of the type of a plate advantageously rigid mounted on dampers. The dampers absorb the energy of the shocks. Shocks are for example gas cylinders, hydraulic, pneumatic or springs or an elastically deformable material element such as the elastomers mentioned above.
Les moyens d'amortissement 2 sont disposés préférentiellement sur le véhicule 1 de sorte à être les premiers éléments du véhicule 1 à entrer en contact avec les structures fixes 5 environnantes, en cas de chocs.The damping means 2 are preferably arranged on the vehicle 1 so as to be the first elements of the vehicle 1 to come into contact with the surrounding fixed structures 5, in case of shocks.
Selon un mode de réalisation avantageux, les moyens d'amortissement 2 sont disposés sur la partie supérieure du véhicule. On entend par partie supérieure du véhicule la partie du véhicule 1 située au dessus du plan longitudinal 4 passant par le centre de gravité du véhicule 1. Le centre de gravité est avantageusement déterminé lorsque le véhicule 1 est hors charge. Ce positionnement des moyens d'amortissement 2 permet d'amortir les chocs, sans risque que les moyens d'amortissement 2 ne rentrent en contact avec les rails situés dans les gares, ou ne gênent l'entrée ou la sortie des passagers.According to an advantageous embodiment, the damping means 2 are arranged on the upper part of the vehicle. The upper part of the vehicle is the part of the vehicle 1 located above the longitudinal plane 4 passing through the center of gravity of the vehicle 1. The center of gravity is advantageously determined when the vehicle 1 is off load. This positioning of the damping means 2 makes it possible to dampen the shocks, without the risk that the damping means 2 come into contact with the rails located in the stations, or interfere with the entry or exit of the passengers.
Selon un autre mode de réalisation, les moyens d'amortissement 2 sont situés au niveau du plan longitudinal 4 passant par le centre de gravité du véhicule 1.According to another embodiment, the damping means 2 are located at the longitudinal plane 4 passing through the center of gravity of the vehicle 1.
Sel o n en co re u n a utre mode de réalisation, les moyens d'amortissement 2 sont disposés dans la partie inférieure du véhicule 1. On entend par partie inférieure du véhicule 1 , la partie du véhicule 1 située au dessous du plan longitudinal 4 passant par le centre de gravité du véhicule 1.According to another embodiment, the damping means 2 are arranged in the lower part of the vehicle 1. By the lower part of the vehicle 1 is meant the part of the vehicle 1 situated below the longitudinal plane 4 passing through the center of gravity of the vehicle 1.
Ce dernier mode de réalisation peut être intéressant pour l'amortissement des chocs même lorsque l'oscillation du véhicule 1 est faible. Selon une variante de l'invention, les structures fixes 5 comprennent des moyens d'amortissement additionnels 6. On entend par structures fixes 5 les obstacles que le véhicule 1 pourrait rencontrer lors de son déplacement le long du câble, telles que les gares d'arrivée, de départ, intermédiaires ou bien encore des pylônes de maintien des câbles.This latter embodiment may be of interest for damping shocks even when the oscillation of the vehicle 1 is low. According to a variant of the invention, the fixed structures 5 comprise additional damping means 6. Fixed structures 5 are the obstacles that the vehicle 1 may encounter when moving along the cable, such as railway stations. arrival, departure, intermediate or even cable towers.
Bien que l'on utilise le terme "additionnels", les moyens d'amortissement additionnels 6 placés sur la structure fixe 5 peuvent réaliser la majeure partie de l'amortissement d'un choc éventuel avec le véhicule 1.Although the term "additional" is used, the additional damping means 6 placed on the fixed structure 5 can realize the majority of the damping of a possible impact with the vehicle 1.
Com m e pou r l es moyen s d'a mortissem ent 2, les moyens d'amortissement additionnels 6 comportent, selon un premier mode de réalisation, un moyen déformable élastiquement. Ce moyen déformable élastiquement comprend selon une première possibilité au moins un matériau déformable élastiquement et selon une deuxième possibilité, une structure déformable élastiquement. Selon un deuxième mode de réalisation, les moyens d'amortissement additionnels 6 comportent des moyens déformables plastiquement. Ce moyen déformable plastiquement comprend soit au moins un matériau déformable plastiquement, soit une structure déformable plastiquement.As in the case of the mortising means 2, the additional damping means 6 comprise, according to a first embodiment, an elastically deformable means. This elastically deformable means comprises, according to a first possibility, at least one elastically deformable material and according to a second possibility, an elastically deformable structure. According to a second embodiment, the additional damping means 6 comprise plastically deformable means. This plastically deformable means comprises either at least one plastically deformable material, or a plastically deformable structure.
Les moyens déformables élastiquement ou plastiquement utilisables pour réaliser les moyens d'amortissement additionnels 6 sont identiques aux moyens déformables élastiquement ou plastiquement cités pour réaliser les moyens d'amortissement 2.The elastically or plastically deformable means for producing the additional damping means 6 are identical to the elastically or plastically deformable means for producing the damping means 2.
Selon une autre possibilité, les moyens d'amortissement additionnels 6 comprennent un élément rigide monté sur des amortisseurs 8 qui permettent d'absorber l'énergie du choc. A titre d'exemple, il peut être utilisé une plaque 7 rigide montée sur des amortisseurs 8 fixés à la structure fixe 5 tel que représenté en figure 1.According to another possibility, the additional damping means 6 comprise a rigid element mounted on dampers 8 which absorb the impact energy. For example, it can be used a rigid plate 7 mounted on dampers 8 fixed to the fixed structure 5 as shown in FIG.
Les amortisseurs 8 disposés entre la plaque 7 et la structure fixe 5 sont du type vérin hydraulique, à gaz, pneumatique, ressort ou autre moyen déformable élastiquement et/ou plastiquement.The dampers 8 disposed between the plate 7 and the fixed structure 5 are of the hydraulic cylinder type, gas, pneumatic, spring or other elastically deformable means and / or plastically.
Que ce soit pour les moyens d'amortissement 2 ou les moyens d'amortissement additionnels 6, la plaque 7 présente avantageusement une rigidité suffisante de sorte à répartir sur toute sa surface les forces d'appui exercées lors de chocs. A titre d'exemple la plaque 7 est fabriquée dans un matériau tel que des plastiques souples.Whether for the damping means 2 or the additional damping means 6, the plate 7 advantageously has sufficient rigidity so as to distribute the support forces over its entire surface. exercised during shocks. For example, the plate 7 is made of a material such as flexible plastics.
La plaque 7 des moyens d'amortissement additionnels 6 est préférentiellement disposée sensiblement parallèle à l'axe longitudinal de la structure fixe 5. Les amortisseurs 8 sont eux d isposés sensiblement perpendiculaires au plan longitudinal de la plaque 7. Ainsi, la reprise des efforts lors du choc entre le véhicule 1 et la structure fixe 5 se fera par l'ensemble de la surface de la plaque 7 en répartissant les forces du choc en forces sensiblement parallèles aux amortisseurs 8. Les amortisseurs 8 travaillent ainsi au meilleur de leur efficacité.The plate 7 of the additional damping means 6 is preferably disposed substantially parallel to the longitudinal axis of the fixed structure 5. The dampers 8 are positioned substantially perpendicular to the longitudinal plane of the plate 7. Thus, the recovery of efforts during the shock between the vehicle 1 and the fixed structure 5 will be through the entire surface of the plate 7 by distributing the shock forces in substantially parallel forces to the dampers 8. The dampers 8 thus work to the best of their effectiveness.
Il est avantageux de combiner, pour les moyens d'amortissement 2 et/ou pour les moyens d'amortissement additionnels 6, une déformation élastique et plastique. Pour cela, on peut utiliser un moyen déformable élastiquement combiné à un moyen déformable plastiquement, ou bien on peut utiliser un moyen configuré pour avoir une limite de déformation élastique correspondant au type de dispositif de l'invention pour avoir déformation élastique puis déformation plastique.It is advantageous to combine, for the damping means 2 and / or for the additional damping means 6, elastic and plastic deformation. For this purpose, it is possible to use an elastically deformable means combined with a plastically deformable means, or else a means configured to have an elastic deformation limit corresponding to the type of device of the invention may be used to have elastic deformation and then plastic deformation.
Selon ces deux modes de réalisation, lors de petits chocs provenant par exem ple d' incidents de fonction nement mineurs, les moyens d'amortissement 2 et/ou additionnels 6 absorberont le choc par déformation élastique sans être endommagés et sans nécessité d'être changés. Alors que lors des chocs pl us importants, q uand la déformation des moyens d'amortissement 2 et/ou additionnels 6 est trop importante, la déformation plastique prend le relais et permet de continuer à absorber les chocs. Dans ce cas, les moyens d'amortissement 2 et/ou additionnels 6 doivent être remplacés pour jouer leurs rôles au prochain choc.According to these two embodiments, during small impacts resulting from, for example, minor operating incidents, the damping means 2 and / or additional means 6 will absorb the shock by elastic deformation without being damaged and without the need to be changed. . While during larger shocks, when the deformation of the damping means 2 and / or additional 6 is too large, the plastic deformation takes over and allows to continue to absorb shocks. In this case, the damping means 2 and / or additional 6 must be replaced to play their roles in the next shock.
Les moyens d'amortissement additionnels 6 sont préférentiellement disposés sur la structure fixe 5 sur toute une surface où le véhicule 1 peut entrer en contact avec. Ainsi, à titre d'exemple, au niveau du pylône de maintien de câble, les moyens d'amortissement additionnels 6 entourent sensiblement tout le pylône au niveau de la hauteur du véhicule 1. Ces moyens couvrent sensiblement toutes les parties du pylône situées au-dessus du passage des véhicules ; à titre d'exemple, la face inférieure des sabots d'un périphérique.The additional damping means 6 are preferably arranged on the fixed structure 5 over an entire surface where the vehicle 1 can come into contact with. Thus, for example, at the level of the cable holding pylon, the additional damping means 6 substantially surround the entire pylon at the height of the vehicle 1. These means substantially cover all parts of the tower located above the passage of the vehicles; for example, the underside of the hooves of a device.
Les moyens d'amortissement additionnels 6 sont donc arrondis, de sorte à être convexes.The additional damping means 6 are therefore rounded, so as to be convex.
Selon une autre possibilité, les moyens d'amortissement additionnels 6 ont un rôle de guidage du véhicule 1 au niveau des structures fixes 5. Par exemple, les moyens d'amortissement additionnels 6 peuvent former un rail de guidage dans les gares du dispositif. Si les moyens d'amortissement additionnels 6 ont un rôle de guidage, il est préférable de prévoir qu'ils soient du type élément rigide monté sur amortisseurs.According to another possibility, the additional damping means 6 have a role of guiding the vehicle 1 at the fixed structures 5. For example, the additional damping means 6 can form a guide rail in the stations of the device. If the additional damping means 6 have a guiding role, it is preferable to provide that they are of the rigid element type mounted on dampers.
Préférentiellement, les moyens d'amortissement 2 et les moyens d'amortissement additionnels 6 sont respectivement disposés sur le véhicule 1 et sur la structure fixe 5 de sorte à coopérer lors de chocs. On entend par "coopérer" que les moyens d'amortissement 2 et les moyens d'amortissement additionnels 6 entrent en contact lors de chocs éventuels.Preferably, the damping means 2 and the additional damping means 6 are respectively disposed on the vehicle 1 and on the fixed structure 5 so as to cooperate during shocks. The term "cooperate" means that the damping means 2 and the additional damping means 6 come into contact during possible shocks.
I l est préférable de prévoir q ue les moyens d'amortissement additionnels 6 sont du type formés à partir de matériau déformable élastiquement et/ou plastiquement quand les moyens d'amortissement 2 sont du type élément rigide monté sur amortisseurs. Inversement, les moyens d'amortissement additionnels 6 sont préférentiellement du type plaque et amortisseur lorsque les moyens d'amortissement 2 sont du type formés à partir de matériaux déformables élastiquement et/ou plastiquement.It is preferable to provide that the additional damping means 6 are of the type formed from elastically and / or plastically deformable material when the damping means 2 are of the rigid element type mounted on shock absorbers. Conversely, the additional damping means 6 are preferably of the plate and damper type when the damping means 2 are of the type formed from elastically and / or plastically deformable materials.
Ceci permet de limiter les frottements entre les différents moyens d'amortissement 2 et 6 tout en préservant un amortissement efficace. This makes it possible to limit the friction between the different damping means 2 and 6 while preserving effective damping.
