L'objet de l'addition se rattache au secteur technique des dispositifs de suspension de véhicules et plus particulièrement aux roues de véhicules, aux essieux et à ltamélioration de l'adhérence des roues. The subject of the addition relates to the technical sector of vehicle suspension devices and more particularly to vehicle wheels, axles and the improvement of wheel grip.

On se réfère plus particulièrement aux revendications 1 à 5 de la Demande de Brevet nO 80-03 531 du 14 février 1980, dont le déposant est également titulaire. Reference is made more particularly to claims 1 to 5 of Patent Application No. 80-03 531 of February 14, 1980, of which the applicant is also the owner.

Suivant l'addition, on a amélioré les moyens de l'invention pour que le double essieu obtenu soit utilisable pour toute valeur de charge, sans être d'un prix de revient excessif. According to the addition, the means of the invention have been improved so that the double axle obtained can be used for any load value, without being of excessive cost price.

On rappelle selon les caractéristiques de la Demande de Brevet, que le double essieu à roues indépendantes, caractérisé en ce qu'il comprend un faux chSssis en une ou plusieurs parties, comprenant deux longerons latéraux présentant à un endroit approprié, un axe d'articulation autorisant la libre rotation de deux bras profilés indépendants et disposés de part et d autre de l'axe d'articulation les les deux bras étant montés et engagés par 1 une de leurs extrémités sur le dit axe, tandis que leur autre extrémité autorise la fixation des moyeux de roues ; les deux bras présentant à un endroit approprié, intermédiaire aux extrémités, un point d'attache et de fixation des extrémités dtun ressort travaillant en traction, et assurant la liaison élastique entre les deux leviers. It will be recalled, according to the characteristics of the Patent Application, that the double axle with independent wheels, characterized in that it comprises a false chassis in one or more parts, comprising two lateral beams having, at an appropriate location, an articulation axis allowing the free rotation of two independent profiled arms arranged on either side of the articulation axis, the two arms being mounted and engaged by one of their ends on said axis, while their other end allows fixing wheel hubs; the two arms having at a suitable location, intermediate at the ends, a point of attachment and fixing of the ends of a spring working in traction, and ensuring the elastic connection between the two levers.

Selon l'addition, la liaison élastique entre les deux bras profilés est obtenue avec l'utilisation d'un ressort agissant en compression, du type ressort à lame, la partie centrale du dit ressort étant rendue solidaire par un étrier au châssis support de l'axe d'articulation des bras. According to the addition, the elastic connection between the two profiled arms is obtained with the use of a spring acting in compression, of the leaf spring type, the central part of said spring being made integral by a stirrup with the support frame of the 'axis of articulation of the arms.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description. These characteristics and others will emerge clearly from the following description.

Pour bien fixer l'objet de l'addition sans toutefois le limiter dans le dessin annexé
La figure 1 est une vue de face schématique illustrant le double essieu suivant l'addition.To fix the object of the addition without limiting it in the attached drawing
Figure 1 is a schematic front view illustrating the double axle according to the addition.

Les figures 2 et 3 sont des vues de côté suivant les lignes Il-Il et 111-
III de la figure 1.Figures 2 and 3 are side views along the lines Il-Il and 111-
III of Figure 1.

Afin de rendre plus concret l'objet de l'addition, on le décrit maintenant d'une manière non limitative illustrée aux figures du dessin. In order to make the object of the addition more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawing.

On rappelle succintement que l'essieu comprend un faux châssis avec deux longerons latéraux et un élément transversal. Chaque extrémité de les sieu est conformée pour autoriser le centrage et la libre rotation des extrémités formant têtes tournantes de deux bras profilés (4 - 5) et opposés, indé pendants l'un de l'autre et constituant les côtés d'une triangulation isocèle. It will be recalled briefly that the axle comprises a subframe with two lateral beams and a transverse element. Each end of the gods is shaped to allow centering and free rotation of the ends forming rotating heads of two profiled arms (4 - 5) and opposite, independent from one another and constituting the sides of an isosceles triangulation .

Ces deux bras sont profilés et coudés pour augmenter l'empatement des roues.These two arms are profiled and bent to increase the wheelbase.

L'autre extrémité des bras présente des moyens autorisant ia fixation des fusées de roues et par suite des moyeux (9 - 10) équipés ou non des dispositifs de freinage.The other end of the arms has means allowing the fixing of the wheel spindles and consequently of the hubs (9 - 10) equipped or not with braking devices.

Selon la Demande de Brevet 80-03 531, les deux bras sont accouplés l'un à l'autre par une liaison élastique, du type dlun ressort hélicoïdal (11) monté de manière à assurer le rappel permanent des riras en position de rap prochement, le ressort précité travaillant essentiellement en traction. According to Patent Application 80-03 531, the two arms are coupled to each other by an elastic connection, of the type of a helical spring (11) mounted so as to ensure the permanent return of the riras in the near rap position. , the aforementioned spring working essentially in traction.

Selon l'addition, la liaison élastique entre les deux bras du double essieu est obtenue par l'utilisation d'un ressort à lames superposées (23)
A cet effet, le ressort à lames est fixe par se partie centrale (231) au cnilssis au moyen d'un étrier (24) et de brides appropriées, et présente ses extrémités (232) recourbées vers le hatot. La lame maitresse (233) du ressort est place en bas du ressort et est maintenue et guidée à coulissement libre sur des supports profilés (25) rendus solldaires des bras profilés (4 - 5).Les dits supports présentant une rainure transversale (251) dans laquelle est engagée à coulisse ment l'extrémité de la lame maitresse. Par l'articulation des deux bras autour de leur axe de rotation, les deux points d'appui de la lame du ressort se rapprochent ou s'éloignent en fonction de la charge appliquée, et du dépiacement des roues lors de l'avancement du véhicule De ce fait, plus la contrainte sur les extrémités du ressort augmente, plus celui-ci se raidit augmentant ainsi sa résistance à la contrainte.Depending on the addition, the elastic connection between the two arms of the double axle is obtained by the use of a superimposed leaf spring (23)
For this purpose, the leaf spring is fixed by its central part (231) to the cnilssis by means of a stirrup (24) and appropriate flanges, and has its ends (232) curved towards the hatot. The master blade (233) of the spring is placed at the bottom of the spring and is held and guided with free sliding on profiled supports (25) made dependent on the profiled arms (4 - 5). Said supports having a transverse groove (251) in which the end of the master blade is slidably engaged. By the articulation of the two arms around their axis of rotation, the two points of support of the leaf of the spring come closer or farther depending on the load applied, and the tracking of the wheels during the advancement of the vehicle Therefore, the more the stress on the ends of the spring increases, the more it stiffens thus increasing its resistance to stress.

Les supports précités solidaires des bras peuvent autre fixes par tous moyens appropriés sur les bras articulés, avec une liberté de réglage éventuel. The aforementioned supports integral with the arms may other fixed by any appropriate means on the articulated arms, with possible freedom of adjustment.

L'addition ne se limite aucunement à celui de ses modes d'application, non plus qu'à ceux des modes de réalisation ayant plus spécialement éte indiqués elle en embrasse au contraire toutes les variantes.  The addition is in no way limited to that of its modes of application, nor to those of the embodiments having more specifically been indicated, on the contrary it embraces all variants.
