Abstract

The support comprises a rigid cross member (21) for holding the steering column (15) which extends from a lateral front vehicle mounting above a longitudinal stiffener (9) of the vehicle floor (8). The cross member is supported by a longitudinal tie rod (23) mounted on a non deformable transverse beam (5) and by an anchoring leg (25) whose base is fixed to the longitudinal floor stiffener. The cross member, the tie rod and the anchoring foot constitute a single ramified assembly whose respective branches carry the parts for fixing to the vehicle structure. The steering column is fixed to another lateral vehicle mounting localised behind the deformation propagation zone of the front vehicle structure. The driver's seat is located behind the deformation propagation zone.

Description

DISPOSITIF DE SUPPORT D'UNE COLONNE DE DIRECTION DE
VEHICULE
L'invention concerne un dispositif de support d'une colonne de direction de véhicule automobile et concerne plus particulièrement un dispositif dont l'agencement évite le recul du volant de direction.DEVICE FOR SUPPORTING A STEERING COLUMN
VEHICLE
The invention relates to a device for supporting a steering column of a motor vehicle and more particularly relates to a device the arrangement of which prevents the steering wheel from rolling back.

L'invention concerne plus particulièrement un dispositif de support d'une colonne de direction dans laquelle une traverse de maintien de la colonne de direction s'étend à partir d'un montant latéral avant du véhicule.The invention relates more particularly to a device for supporting a steering column in which a cross-member for holding the steering column extends from a front pillar of the vehicle.

On sait qu'un choc frontal, au cours duquel la structure avant du véhicule est enfoncée, engendre des réactions longitudinales dans l'arbre et la colonne de direction. Lorsque ces réactions atteignent le tronçon de l'arbre auquel est fixé le volant, celui-ci recule légèrement dans l'habitacle et vers le thorax du conducteur du véhicule.It is known that a frontal impact, during which the front structure of the vehicle is depressed, generates longitudinal reactions in the shaft and the steering column. When these reactions reach the section of the shaft to which the steering wheel is attached, the latter moves back slightly into the passenger compartment and towards the thorax of the driver of the vehicle.

Pour remédier à cet inconvénient la publication FR-A-2.021.078 propose une liaison dans laquelle le carter est fixé sur un berceau support orienté longitudinalement, susceptible d'être dévié vers le bas sous l'action d'une force d'enfoncement de la structure avant du véhicule.To remedy this drawback, the publication FR-A-2.021.078 proposes a connection in which the casing is fixed on a support cradle oriented longitudinally, capable of being deflected downward under the action of a driving force of the front structure of the vehicle.

La publication FR-A-2. 154.910 décrit une colonne de direction dans laquelle l'arbre de direction, sous l'effet d'un choc frontal, vient en appui sur un moyen de butée rigidement relié à une structure indéformable. Un tel moyen de butée tend à provoquer un déplacement du volant en l'éloignant du thorax du conducteur.The publication FR-A-2. 154.910 describes a steering column in which the steering shaft, under the effect of a frontal impact, comes to bear on a stop means rigidly connected to a non-deformable structure. Such a stop means tends to cause the steering wheel to move away from the driver's chest.

Lorsque la structure avant est soumise à un choc décalé, les liaisons précitées demeurent inopérantes si bien qu'une partie de l'effort de déformation est transmise à la colonne et à l'arbre de direction. La déformation plastique de la structure au cours de l'absorption d'énergie ne peut dans ce cas empecher le recul de l'arbre de direction lorsque ce dernier est constitué par deux tronçons réunis par un joint de transmission.When the front structure is subjected to an offset shock, the aforementioned links remain inoperative so that part of the deformation force is transmitted to the column and to the steering shaft. The plastic deformation of the structure during the absorption of energy cannot in this case prevent the recoil of the steering shaft when the latter consists of two sections joined by a transmission joint.

L'invention a ainsi pour objet un dispositif de support d'une colonne de direction dans laquelle l'arbre de direction possède au moins deux tronçons supportés par deux ensembles respectifs de la structure dont le premier est susceptible d'être déplacé au cours du choc et dont l'autre sensiblement indéformable supporte la colonne de direction.The invention thus relates to a device for supporting a steering column in which the steering shaft has at least two sections supported by two respective sets of the structure, the first of which is capable of being displaced during the impact. and the other substantially non-deformable supports the steering column.

Selon l'invention la colonne de direction est rigidement reliée à un élément de traverse dont une extrémité est solidaire d'un montant latéral de la structure du véhicule opposé à la zone du choc et qui est soutenue par un tirant longitudinal monté en butée sur une poutre transversale indéformable et par un pied d'ancrage dont la base est fixée à un élément de renforcement longitudinal du plancher du véhicule.According to the invention, the steering column is rigidly connected to a cross member, one end of which is secured to a lateral upright of the structure of the vehicle opposite to the impact zone and which is supported by a longitudinal tie rod mounted in abutment on a non-deformable transverse beam and by an anchoring foot, the base of which is fixed to a longitudinal reinforcement element of the vehicle floor.

Le dispositif ainsi réalisé est particulièrement rigide et s'oppose à toute modification de la position du volant de direction au cours d'une déformation de la structure avant du véhicule consécutivement à un choc avant décalé et localisé devant le conducteur du véhicule.The device thus produced is particularly rigid and opposes any modification of the position of the steering wheel during a deformation of the front structure of the vehicle following a front impact offset and located in front of the driver of the vehicle.

D'autres caractéristiques du dispositif apparaîtront à la lecture de la description d'un exemple de réalisation de celui-ci, en référence au dessin annexé dans lequel - la figure I est une représentation schématique en élévation de la partie
avant d'une structure de l'habitacle d'un véhicule automobile utilisant le
dispositif support conforme à l'invention.Other characteristics of the device will appear on reading the description of an exemplary embodiment thereof, with reference to the appended drawing in which - Figure I is a schematic elevation of the part
front of a structure of the passenger compartment of a motor vehicle using the
support device according to the invention.

- la figure 2 est une représentation en plan de la structure représentée à la
figure 1.- Figure 2 is a plan view of the structure shown in
figure 1.

- la figure 3 est une représentation perspective du support de fixation de
la colonne de direction.- Figure 3 is a perspective representation of the mounting bracket of
the steering column.

Les figures 1 et 2 représentent la partie avant d'une structure de l'habitacle 1 d'un véhicule automobile, susceptible de se déformer au cours d'un choc frontal agissant dans le sens de la flèche F.Figures 1 and 2 show the front part of a structure of the passenger compartment 1 of a motor vehicle, capable of deforming during a frontal impact acting in the direction of arrow F.

La structure 1 est séparée d'un bloc avant 2 également déformable par une cloison pare-feu 3 dont la partie supérieure est raccordée à l'ossature 4 de la planche de bord solidaire d'une poutre transversale indéformable 5 support du pare-brise 6 du véhicule. The structure 1 is separated from a front unit 2 also deformable by a firewall 3 whose upper part is connected to the frame 4 of the dashboard secured to a non-deformable transverse beam 5 support for the windshield 6 of the vehicle.

La cloison pare-feu 3 est également raccordée au plancher 8 du véhicule rigidifié notamment par un renfort longitudinal 9 dont la configuration permet de loger un certain nombre d'organes fonctionnels du véhicule telle qu'une tubulure d'échappement.The firewall 3 is also connected to the floor 8 of the rigidified vehicle, in particular by a longitudinal reinforcement 9, the configuration of which makes it possible to house a certain number of functional members of the vehicle such as an exhaust pipe.

La poutre 5 est assemblée aux montants latéraux avant 10, 10' de la carrosserie du véhicule qui limitent les ouvertures d'encadrement des portes dudit véhicule.The beam 5 is assembled to the front lateral uprights 10, 10 ′ of the vehicle body which limit the frame openings of the doors of said vehicle.

Selon l'invention un dispositif désigné dans son ensemble par la référence 20 supporte la colonne de direction 15 portant les paliers d'un arbre de direction 16 dont les tronçons avant 16a et arrière 16b sont réunis par un joint de transmission 17 du mouvement de rotation communiqué par le volant 18 à un mécanisme de direction non représenté localisé dans le bloc avant 2. Le tronçon arrière 16b de l'arbre de direction peutêtre lui-même réalisé de manière en soi connue en deux parties coaxiales susceptibles d'un déplacement relatif consécutivement au choc avant. Le dispositif de support 20 de la colonne de direction 15 est constitué conformément à l'invention par une traverse de maintien 21 rigide dont chaque extrémité porte une bride de fixation 22 dont l'une est vissée sur le montant latéral
10 et dont l'autre est vissée sur la colonne 15.According to the invention a device designated as a whole by the reference 20 supports the steering column 15 carrying the bearings of a steering shaft 16 whose front sections 16a and rear 16b are joined by a transmission joint 17 of the rotational movement communicated by the steering wheel 18 to a steering mechanism (not shown) located in the front unit 2. The rear section 16b of the steering shaft can itself be produced in known manner in two coaxial parts capable of relative displacement consecutively to the front shock. The support device 20 for the steering column 15 is constituted in accordance with the invention by a rigid cross member 21, each end of which carries a fixing flange 22, one of which is screwed to the lateral upright
10 and the other of which is screwed onto column 15.

La traverse de maintien 21 s'étend de la sorte à partir du montant 10 situé hors de la zone de choc, au-dessus du renfort longitudinal 9 jusqu'à la colonne 15. La position de la traverse 21 est maintenue selon une particularité du dispositif. par un tirant longitudinal 23 de fixation vissé au contact de la poutre 5 dans une zone non déformée lors d'un choc décalé et rigidement relié à la traverse 21. Dans le but d'éviter l'affaissement de la traverse, un pied d'ancrage 25 est également rigidement relié à la traverse 21 et fixé par sa base au renfort longitudinal 9, dans une zone non affectée sensiblement par les déformations dues au choc.The retaining cross member 21 extends in this way from the upright 10 located outside the impact zone, above the longitudinal reinforcement 9 to the column 15. The position of the cross member 21 is maintained according to a particular feature of the device. by a longitudinal tie rod 23 of fixing screwed in contact with the beam 5 in a non-deformed zone during an offset shock and rigidly connected to the cross-member 21. In order to avoid the collapse of the cross-member, a foot of anchor 25 is also rigidly connected to the cross member 21 and fixed by its base to the longitudinal reinforcement 9, in an area not significantly affected by the deformations due to impact.

La figure 3 représente l'ensemble du support 20 ramifié dont les branches, constituées par le tirant 23 et par le pied 25, sont portées par la traverse 21. La traverse 21 et ses ramifications 23, 25 portent les divers organes de boulonnerie qui assurent la liaison de l'ensemble 20 aux éléments de la structure du véhicule respectivement constitués par la poutre 5, le renfort 9 et par le montant 10.FIG. 3 represents the assembly of the branched support 20 whose branches, constituted by the tie rod 23 and by the foot 25, are carried by the cross member 21. The cross member 21 and its ramifications 23, 25 carry the various bolting members which provide the connection of the assembly 20 to the elements of the vehicle structure respectively constituted by the beam 5, the reinforcement 9 and by the upright 10.

Il est toutefois possible de solidariser la colonne de direction 15 avec le montant 10' localisé derrière la zone de choc. Dans cette hypothèse la propagation de la déformation de la structure avant du véhicule doit être limitée audit montant, sans engendrer de déplacement de la colonne de direction.It is however possible to secure the steering column 15 with the upright 10 'located behind the shock zone. In this case, the propagation of the deformation of the front structure of the vehicle must be limited to said amount, without causing displacement of the steering column.

Sans sortir du cadre de l'invention celle < i est applicable aux véhicules indépendamment de la localisation à droite ou à gauche du siège du conducteur étant bien entendu que celui-ci est principalement situé derrière la zone de propagation de la déformation de la structure avant du véhicule. Without departing from the scope of the invention, that <i is applicable to vehicles regardless of the location to the right or to the left of the driver's seat, it being understood that this is mainly located behind the area of propagation of the deformation of the front structure of the vehicle.
