dans le châssis.in the chassis.

Cette disposition présente certains inconvénients.  This arrangement has certain disadvantages.

En particulier, l'encombrement, dans le sens de la hauteur, des ressorts, conduit à un châssis à haute altitude au-dessus de la voie; si on veut abaisser l'altitude du châssis, on est conduit à y percer un orifice de passage des ressorts et à y ajuster un logement; il en résulte une complication dans la réalisation du  In particular, the congestion, in the sense of the height of the springs, leads to a chassis at high altitude above the track; if we want to lower the altitude of the frame, we are led to drill there a hole of passage of the springs and to adjust a housing there; This results in a complication in the implementation of the

châssis et un affaiblissement de sa rigidité.  chassis and a weakening of its rigidity.

Un but de la présente invention est de réaliser une suspension permettant l'abaissement de l'altitude du châssis sans compliquer  An object of the present invention is to provide a suspension for lowering the altitude of the chassis without complicating

la réalisation de celui-ci.the realization of it.

Dans certaines suspensions de type connu, les faces d'appui  In certain suspensions of known type, the bearing faces

des ressorts sont inclinées par rapport à leur déplacement horizontal.  springs are inclined with respect to their horizontal displacement.

Les déplacements horizontaux des ressorts liés à leur raideur  The horizontal displacements of the springs linked to their stiffness

longitudinale, conduisent à un raidissement important de la suspension.  longitudinal, lead to a significant stiffening of the suspension.

On est donc incité à installer des ressorts plus souples pour obtenir  We are therefore encouraged to install more flexible springs to obtain

le fonctionnement souhaité.the desired operation.

Un autre but de l'invention est de réaliser une suspension moins raide que celle de l'art connu, en utilisant mieux la flexibilité  Another object of the invention is to provide a less stiff suspension than that of the prior art, by making better use of the flexibility

des ressorts.springs.

L'invention a pour objet une suspension primaire pour véhicule comprenant pour chaque essieu, deux bottes d'essieu reliées chacune au châssis par une rotule, caractérisée en ce qu'à chaque botte d'essieu sont associés deux groupes de ressorts disposés de part et d'autre de la botte d'essieu, chaque ressort prenant appui, à une extrémité, directement sur le châssis et à l'autre extrémité, sur un bras solidaire de la botte d'essieu et constituant un appui  The invention relates to a primary vehicle suspension comprising for each axle, two axle boots each connected to the chassis by a ball joint, characterized in that each axle boot are associated two groups of springs arranged on each side. other axle boot, each spring bearing, at one end, directly on the frame and at the other end, on an arm secured to the axle boot and constituting a support

sensiblement horizontal.substantially horizontal.

Dans un mode particulier de réalisation l'appui d'au moins un groupe de ressorts sur le bras se fait par l'intermédiaire d'une  In a particular embodiment the support of at least one group of springs on the arm is via a

pièce pivotante.swivel piece.

et 3 s'étendant horizontalement de part et d'autre de la botte.  and 3 extending horizontally on either side of the boot.

Le bras 3 est prolongé par une rotule 4 d'articulation de la botte  The arm 3 is extended by a knee joint 4 of the boot

et du châssis 5.and chassis 5.

Selon l'invention, deux groupes de ressorts 6 et 7 sont placés de part et d'autre de la botte d'essieu et s'étendent entre, d'une  According to the invention, two groups of springs 6 and 7 are placed on either side of the axle boot and extend between,

part, le châssis 5 et d'autre part les bras 2 et 3 respectivement.  on the other hand, the chassis 5 and on the other hand the arms 2 and 3 respectively.

Pour la simplicité du dessin, chaque groupe de ressort ne comprend qu'un ressort, mais il peu y avoir pour chaque groupe  For simplicity of design, each group of spring includes only one spring, but there can be for each group

deux ressorts coaxiaux.two coaxial springs.

On obtient ainsi un châssis surbaissé, sans nécessiter d'y perforer des orifices de passage des ressorts et d'y placer des  This results in a low-profile chassis, without the need to perforate orifices for the passage of the springs and to place therein

logements d'appui.support housing.

Les ressorts fonctionnent plus logiquement que dans l'art antérieur et on utilise ainsi de manière plus satisfaisante leur  The springs operate more logically than in the prior art and thus their
