Description

Suspension pour véhicule notamment pour vehicule léger.  Suspension for vehicle, in particular for light vehicle.

La présente invention concerne les suspensions de véhicules légers dans lesquelles le moyeu de roue est port2 ?ar un bras dit trompette articulé à l'extrémite de la traverse d'essieu. La suspension est constituée par une tige formant bielle articulée à une extrémité à l'extréeité d'une manivelle solidaire de la trompette et attelée à ltautre extrémité à un ressort de compression logé dans un pot solidaire du châssis et-la suspension est amortie de la manière usuelle par un amortisseur à friction ou hydraulique.The present invention relates to suspensions for light vehicles in which the wheel hub is carried by a so-called trumpet arm articulated at the end of the axle cross member. The suspension consists of a rod forming a connecting rod articulated at one end at the end of a crank secured to the trumpet and coupled at the other end to a compression spring housed in a pot secured to the chassis and the suspension is damped by the usual way by a friction or hydraulic damper.

Cette suspension qui a l'avantage d'assurer une suspension indépendante pour les quatre roues est encombrante et de grande longueur, ce qui oblige à écarter les traverses d'essieu et empêche de réaliser un véhicule court, et les amortisseurs, comme les amortisseurs généralement connus, ont une force de freinage, c'est-à-dire un effet d'amortissement, indépendant de la charge.This suspension, which has the advantage of providing an independent suspension for the four wheels, is bulky and very long, which means that the axle crosspieces have to be spread and prevents a short vehicle from being produced, and the shock absorbers, like the shock absorbers generally. known, have a braking force, that is to say a damping effect, independent of the load.

La présente invention a pour but de remédier à ces inconvénients en réalisant une suspension d'encombrement réduit dans laquelle la force de freinage de l'amortisseur est élevée sous charge et proportionnelle à la charge dans les phases de compression de la suspension mais faible, en donnant une suspens ion souple, dans les phases de détente de la suspension.The object of the present invention is to remedy these drawbacks by providing a suspension of reduced size in which the braking force of the damper is high under load and proportional to the load in the compression phases of the suspension but low, in giving a flexible suspension, in the relaxation phases of the suspension.

Le résultat est atteint conformément à l'invention par le fait que la réaction du pot de suspension est appliquée à une mâchoire d'amortissement pour la forcer en appui à frottement sur un tambour solidaire de la trompette, tambour qui est coaxial à l'articulation de la trompette sur la traverse d'essieu.The result is achieved in accordance with the invention by the fact that the reaction of the suspension pot is applied to a damping jaw to force it into friction bearing on a drum integral with the trumpet, a drum which is coaxial with the articulation of the trumpet on the axle crossmember.

En pratique le tambour est constitué par le manchon cylindrique de la trompette dans lequel sont logés les roulements d'articulation sur la traverse. La'mâchoire en secteur cylindrique est prolongée par un flasque partant de son bord axial inférieur, flasque dont l'extrémité est articulée sur un gousset horizontal solidaire du châssis, la tige de la suspension traversant le flasque de la mâchoire pour agir sur la manivelle et le pot du ressort de suspension prenant appui sur la face arrière du flasque.In practice, the drum consists of the cylindrical sleeve of the trumpet in which the articulation bearings are housed on the crosspiece. The jaw in the cylindrical sector is extended by a flange starting from its lower axial edge, flange the end of which is articulated on a horizontal gusset secured to the chassis, the rod of the suspension passing through the flange of the jaw to act on the crank and the pot of the suspension spring resting on the rear face of the flange.

On décrira ci-après un exemple de réalisation de la suspension conforme à l'invention avec référence au dessin ci-annexé dans lequel
la figure 1 est une vue en perspective avec
arrachement partiel d'un côté de la suspension
et la figure 2 une vue en perspective de la
suspension à l'état démonté.An embodiment of the suspension according to the invention will be described below with reference to the attached drawing in which
Figure 1 is a perspective view with
partial pullout on one side of the suspension
and Figure 2 a perspective view of the
suspension in disassembled state.

Dans les dessins, la référence 1 désigne un longeron représenté très schématiquement et 2 les traverses d'essieux qui portent par un axe avec roulements à billes 3, le manchon de trompette 4 d'où part la trompette 5 qui porte le tambour de roue et la roue, non représentés. La référence 6 désigne un flasque formant manivelle, solidaire du manchon de trompette et sur lequel est articulée en 7-la tige de traction de la suspension. L'ensemble ci-dessus est un ensemble connu auquel est appliquée l'invention.In the drawings, the reference 1 designates a spar shown very schematically and 2 the axle crosspieces which carry by an axis with ball bearings 3, the trumpet sleeve 4 from which the trumpet 5 which carries the wheel drum leaves and the wheel, not shown. The reference 6 designates a flange forming a crank, integral with the trumpet sleeve and on which is articulated in 7-the traction rod of the suspension. The above assembly is a known assembly to which the invention is applied.

Conformément à l'inventiondes goussets 8 sont boulonnés, à travers des trous 9,sous le longeron de manière qu'un de leurs bords 10,perpendiculaire au longeron, se trouve sensiblement au droit du manchon de trompette. Deux trous ll sont réalisés dans le gousset sur une parallèle au bord 10
L'amortisseur à frottement est constitué par une mâchoire en secteur cylindrique 12 portant une garniture interne 13 qui s'adapte sur la surface du.. manchon de trompette 4. De l'un des bords longitudinaux de la mâchoire part un flasque 14 qui porte sur son bord opposé deux goujons filetés 15 au même écartement qie les trous 11.Au montage les goujons 15 sont enfilés dans les trous ll avec interposition de bagues en caoutchouc dur 16 de part et d'autre du gousset 8 et l'en- semble est bloqué. par des écrous 17. Un trou 18 pour le passage de la tige de traction de la suspension est prévu dans le flasque 14.According to the invention, the gussets 8 are bolted, through holes 9, under the spar so that one of their edges 10, perpendicular to the spar, is located substantially in line with the trumpet sleeve. Two holes ll are made in the gusset on a parallel to the edge 10
The friction damper is constituted by a jaw in cylindrical sector 12 carrying an internal lining 13 which fits on the surface of the .. trumpet sleeve 4. From one of the longitudinal edges of the jaw leaves a flange 14 which carries on its opposite edge two threaded studs 15 at the same spacing qie the holes 11.At mounting the studs 15 are threaded into the holes ll with interposition of hard rubber rings 16 on either side of the gusset 8 and the assembly is blocked. by nuts 17. A hole 18 for the passage of the suspension pull rod is provided in the flange 14.

La suspension comporte un pot 19, un ressort 20, une coupelle d'appui 21, une tige filetée 22 avec un écrou 23 vissé sur une extrémité de la tige 22 et formant butée pour la coupelle de ressort. Sur l'autre extrémité de la, tige filetée 22 qui est engagée dans le trou 18 du flasque 14 vient se visser le manchon de la fourchette 24 d'attelage sur l'extrémité du flasque 6.The suspension comprises a pot 19, a spring 20, a support cup 21, a threaded rod 22 with a nut 23 screwed onto one end of the rod 22 and forming a stop for the spring cup. On the other end of the, threaded rod 22 which is engaged in the hole 18 of the flange 14 is screwed the sleeve of the coupling fork 24 on the end of the flange 6.

Le pot 19 vient en butée sur la face du flasque 14 Opposée au flasque 6 et la mise en comEression du ressort 20 force la garniture 13 de la mâchoire 12 en appui sur le manchon de trompette 4 avec une force qui est proportionnelle à la charge.The pot 19 abuts on the face of the flange 14 Opposite the flange 6 and the setting in comEression of the spring 20 forces the lining 13 of the jaw 12 bearing on the trumpet sleeve 4 with a force which is proportional to the load.

On obtient ainsi une suspension peu encombrante avec un effet d'amortissement proportionnel à la charge. A space-saving suspension is thus obtained with a damping effect proportional to the load.
