The assembly 10 also comprises two triangles 24 of suspension each of which forms a connecting rod which connects man st articulated "a door -fusée 1. 6 associated with the support 14 centrai. Without limitation, each tria ng 24 is here realized from a metal sheet.
Les triangles 24 de suspension présentent une structure identique et ils sont agen cés symétriquement en miroir par rapport à un pian longitudinal, vertical  The triangles 24 of suspension have an identical structure and they are symmetrically arranged in mirror with respect to a vertical longitudinal plane.
Chaque triangle 24 de suspension présente ainsi u ne extrémité 28 tra nsversalement externe q ui forme un premier sommet du triangle. Chaque triangle 24 de suspension comporte aussi une première extrémité 28 transversa le interne avant et une deu xième extrémité 30 tra nsversale interne arrière . Ces deux extrémités 28, 30 transversales internes forment les deu xième et troisième sommets du triangle 24.  Each suspension triangle 24 thus has an end 28 tra nsversalement external q ui which forms a first vertex of the triangle. Each suspension triangle 24 also has a first end 28 transverse the inner front and a second end 30 tra nsversal rear internal. These two inner transverse ends 28, 30 form the second and third vertices of the triangle 24.
Pour chaq ue tria ng le 24 de suspension , les deux extrémités 28 , 30 transversales internes sont alignées sur un même axe " B" long itudinal.  For each tria ng the suspension 24, the two ends 28, 30 internal transverse are aligned on a same axis "B" long longitudinal.
L'extrémité 26 transversale externe est décalée transversalement vers l'extérieu r par rapport audit axe "B". elle est Song itudinalement comprise entre les deux extrémités 28 , 30 transversales internes. L'extrémité 26 transversale externe est plus précisément agencée longitud maternent plus proche de l'extrémité 30 transversale inte rne arrière q ue de l'extrémité 28 transversale interne avant.  The outer transverse end is shifted transversely outwardly with respect to said "B" axis. it is principally between the two ends 28, 30 transverse internal. The outer transverse end is more precisely arranged longitudinal closer to the rear transverse end than to the front inner transverse end.
C haque triangle 24 de suspension est monté pivotan t d irectement sur le support 14 de liaison autou r d'un axe "B" longitudinal par l'intermédiaire de ses deux extrémités 28, 30 transversales internes. Un tel agencement permet de conférer à l'ensemble 10 une rigidité longitudinale. Each triangle 24 of suspension is mounted pivotally td irectely on the support 14 of link r or a axis "B" longitudinal through its two ends 28, 30 internal transverse. Such an arrangement makes it possible to give the assembly 10 longitudinal rigidity.
Chaque porte-fusée 18 est monté pivotant autour d'un axe "C" longitudinal sur l'extrémité 26 transversale externe d'un triangle 24 de suspension associé.  Each knuckle 18 is pivotally mounted about a longitudinal axis "C" on the outer transverse end of a triangle 24 of associated suspension.
Le moteur 12 est agencé transversalement entre les deux triangles 24 de suspension, il comporte un carter 32 rigide.  The motor 12 is arranged transversely between the two triangles 24 of suspension, it comprises a housing 32 rigid.
Le support 14 de liaison comporte le carter 32 du moteur 12 et un élément 34 de structure qui s'étend transversalement en parallèle avec le carter 32 du moteur 12. Dans le mode de réalisation représenté aux figures, le moteur 12 est agencé en avant de l'élément 34 de structure.  The connection support 14 comprises the housing 32 of the motor 12 and a structural element 34 which extends transversely in parallel with the housing 32 of the motor 12. In the embodiment shown in the figures, the motor 12 is arranged in front of the element 34 of structure.
Le carter 32 du moteur 12 est destiné à être fixé sous la caisse 15 du véhicule, comme représenté à la figure 3, A cet effet, le carter 32 comporte ici deux brides 38 opposées de fixation en forme d'oreilles qui s'étendent transversalement à chaque extrémité transversale du carter 32. Chaque bride 36 comporte un perçage 38 qui est destiné à recevoir une vis verticale de fixation sous la caisse 15 du véhicule. Les deux perçages 38 sont alignés transversalement. Le carter 32 est ainsi fixé en deux points à la caisse 15 du véhicule.  The casing 32 of the motor 12 is intended to be fixed under the body 15 of the vehicle, as shown in FIG. 3. For this purpose, the casing 32 here comprises two opposite ear-shaped fastening flanges 38 extending transversely. at each transverse end of the housing 32. Each flange 36 has a bore 38 which is intended to receive a vertical fixing screw under the body 15 of the vehicle. The two holes 38 are aligned transversely. The casing 32 is thus fixed at two points to the body 15 of the vehicle.
Les perçages 38 sont agencés dans le même pian vertical transversal que les premières extrémités 28 internes avant des triangles 24 de- suspension.  The holes 38 are arranged in the same transverse vertical plane as the first inner ends 28 before triangles 24 of suspension.
L'élément 34 de structure comporte un cadre 35 qui s'étend dans un pian globalement vertical II s'agit ici d'un cadre 35 qui présente une grande rigidité dans un pian vertical transversal. Le cadre 35 comporte ainsi deux traverses 40 transversales supérieure et inférieure qui sont reliées entre elles par deux montants 42 verticaux latéraux, Des membrures 44 s'étendent verticalement en travers du cadre 35 pour en assurer la rigidité, Les traverses 40 et les montants 42 sors* par exemple formés par des profilés métalliques . The structure element 34 comprises a frame 35 which extends in a generally vertical plane. This is a frame 35 which has a high rigidity in a transverse vertical plane. The frame 35 thus has two transverse upper and lower transverse crosspieces 40 which are interconnected by two lateral vertical uprights 42. Frames 44 extend vertically across the frame 35 to ensure their rigidity. The cross members 40 and the posts 42 are for example formed by metal profiles.
L'élément 34 de structure comporte deux brides 48 supérieures de fixation so us la caisse 1 5 du véhicule. Chaq ue bride 46 est agencée à un coin supérieur transversal du cad re 35. Les deux brides 48 sont ici montées pivotantes autour d'un axe "D" transversai commun sur le cadre 35 pour permettre un pivotement du cadre 35 par rapport à la caisse 1 5 d u véhicule .  The structure element 34 comprises two upper clamps 48 for securing the body 1 5 of the vehicle. Each flange 46 is arranged at a transverse upper corner of frame 35. The two flanges 48 are here pivotally mounted about a common transverse axis "D" on the frame 35 to allow pivoting of the frame 35 relative to the body 1 5 of the vehicle.
Eta nt don né que le carter 32 du moteur 1 2 est directement fixé sous la caisse 1 5 d u véhicule. L'élément 34 de structu re ne supporte pas le poids du moteur 1 2.  As a result, the housing 32 of the engine 1 2 is directly fixed under the body 1 5 of the vehicle. The element 34 of structu re does not support the weight of the engine 1 2.
La première extrémité 28 interné ava nt de chaq ue triang le 24 de suspension est montée pivotante autour de l'axe "B" directement sur le carier 32 d u moteur 12, tandis que la deuxième extrémité 30 in terne arrière de chaque triangle 24 de suspension est montée pivota nte autour de l'axe "B" sur le cadre 35 de l'élément 34 de structure ,  The first end 28 interned has each triangle 24 of the suspension is pivotally mounted about the axis "B" directly on the carrying 32 of the engine 12, while the second rear end 30 in dull of each triangle 24 suspension is rotatably mounted around axis "B" on frame 35 of structure element 34,
Plus précisément, chaque deuxième extrémité 30 interne arrière est montée pivotante sur un coin inférieur transversal associé d u cadre 35.  Specifically, each rearward inner second end is pivotably mounted on an associated transverse lower corner of frame 35.
Le moteur 1 2 comporte un arbre moteur (non représenté) d'axe transversal. De ce fait, lorsque l'a rbre moteu r est entraîné en rotation dans un sens, le carier 12 est soumis en réaction à un couple tournant en sens contraire. Ce couple tend à faire tourner le carter 32 autour d'un axe passant par ses deux points de fixation alignés transversalemen t. Pour amortir et limiter Ses effets de ce couple, le carter 32 du moteur comporte un bras 48 qui s'étend globalement iongltudinalemenf depuis l'arrière du carter 32 jusqu'à la traverse 40 supérieure du cadre 35. L'extrémité longitudin ale arrière du bras 48 est monté pivotante autour d'un axe " E" transversal sur la traverse 40 s upérieure du cadre 35, L'axe "E" de pivotement est agencé à proximité de i'axe "D" de pivotement du cadre 35. En variante non représentée de l' invention, le bras 48 est fixe à la caisse 15 dis véhicule. The motor 1 2 comprises a motor shaft (not shown) of transverse axis. As a result, when the motor is rotated in one direction, the carrier 12 is responsive to a counter-rotating torque. This torque tends to rotate the housing 32 about an axis passing through its two attachment points aligned transversally t. To dampen and limit its effects of this torque, the casing 32 of the motor comprises an arm 48 which extends globally iongltudinalemenf from the rear of the housing 32 to the cross 40 of the upper frame 35. The longitudinal end ale back of arm 48 is pivotally mounted about a transverse axis "E" on the cross member 40 s upstream of the frame 35, the axis "E" pivoting is arranged near the axis "D" of pivoting frame 35. In a variant not shown of the invention, the arm 48 is fixed to the body 15 dis vehicle.
L'arbre moteur est destiné à entraîner en rotation deux arbres 49 globalement transversaux de transmission qui sont liés aux roues par l'intermédiaire de cardans.  The motor shaft is intended to drive in rotation two generally transverse transmission shafts 49 which are connected to the wheels by means of gimbals.
L'ensemble 10 comporte aussi deux bieilettes 50 transversales dites "bieilettes 50 de pince" dont chacune s'étend depuis un porte-fusée 18 associé jusqu'au carter 32 du. moteur 12. Chaque extrémité de bieiiette 50 est montée pivotante autour d'un axe longitudinal. Les bieilettes 50 ont pour fonctions d'empêcher le débattement des porte-fusées autour d'un axe vertical, permettant ainsi aux roues arriére de conserver une orientation constante par rapport â la direction longitudinale de déplacement du véhicule. Chaque bieiiette 50 s'étend parallèlement au triangle 24 de suspension, formant ainsi avec le triangle 24 associé de suspension une articulation en parallélogramme du porte-fusée 18 par rapport au support 14 de liaison. The assembly 10 also comprises two transverse 50 bieilettes 50 called "bieilettes 50" each of which extends from a stub axle 18 associated to the casing 32 of . 12. Each end of bieiiette 50 is pivotally mounted about a longitudinal axis. Bieilettes 50 have the function of preventing the deflection of the stub axles around a vertical axis, thus allowing the rear wheels to maintain a constant orientation relative to the longitudinal direction of movement of the vehicle. Each piece 50 extends parallel to the triangle 24 of suspension, thus forming with the triangle 24 associated suspension a parallelogram articulation of the knuckle 18 relative to the support 14 connecting.
L'ensemble 10 est susceptible d'être assemblé préalablement à son montage sur le véhicule automobile. Les différents composants de l'ensemble 10 ainsi assemblés sont solidaires les uns des autres, ce qui rend beaucoup plus simple le positionnement et la fixation de l'ensemble 10 sur la caisse 15 du véhicule. Un tel ensemble 10 peut ainsi être assemblé en un lieu différent du site de. montage sur la caisse 15 du véhicule, puis transporté jusqu'au site de montage.  The assembly 10 is capable of being assembled prior to its mounting on the motor vehicle. The various components of the assembly 10 thus assembled are integral with each other, which makes it much easier to position and secure the assembly 10 on the body 15 of the vehicle. Such an assembly 10 can thus be assembled in a place different from the site of. mounting on the body 15 of the vehicle, then transported to the mounting site.
Lorsque l'ensemble 10 est monté sur le véhicule, une partie du poids de la caisse 15 transite directement depuis la caisse 15 du véhicule jusqu'aux triangles 24 de suspension en passant par le carter 32 du moteur, tandis qu'une autre partie de ces efforts passe par l'élément 34 dé structure sans passer par le carter 32 du moteur 12. Un tel ensemble 10 dans lequel une partie du poids de la -caisse 15 est portée par le carter 32 du moteur tandis que l'autre partie du poids est portée par un élément de structure 34 est désigné sous le terme d'ensemble "semi-porteur". When the assembly 10 is mounted on the vehicle, part of the weight of the body 15 passes directly from the body 15 of the vehicle to the suspension triangles 24 through the housing 32 of the engine, while another part of these forces passes through the element 34 of structure without passing through the housing 32 of the engine 12. Such an assembly 10 wherein a portion of the weight of the -caisse 15 is carried by the housing 32 of the engine while the other part weight is carried by a structural element 34 is referred to as a "semi-carrier" assembly.
Lors du déplacement du véhicule, des efforts dynamiques transversaux et longitudinaux agissent sur ia caisse 15 du véhicule et/ou sur les porte-fusées.  During the movement of the vehicle, transverse and longitudinal dynamic forces act on the body 15 of the vehicle and / or on the stub axles.
L'élément 34 de structure permet de conférer au support 14 de liaison une grande rigidité transversale. Cette fonction de l'élément 34 de structure est confortée par son agencement au plus proche de l'axe passant transversalement par les extrémités 26 externes des triangles 24 de suspension . De ce fait, une majeure partie des efforts dynamiques transversaux transite entre les triangles 24 de suspension et ia caisse 15 du véhicule via l'élément 34 de structure, tandis que l'autre partie de ces efforts transite via le carter 32 du moteur 12,  The structure element 34 makes it possible to give the support 14 a high degree of transverse rigidity. This function of the element 34 of structure is supported by its arrangement closer to the axis passing transversely by the outer ends 26 of the triangles 24 suspension. As a result, a greater part of the transverse dynamic forces passes between the suspension triangles 24 and the vehicle body 15 via the structure element 34, while the other part of these forces passes via the housing 32 of the engine 12,
Un tel agencement est avantageusement plus simpie qu'une architecture â berceau comme décrite dans l'état de la technique. L'élimination du berceau et son remplacement par le carier 32 et par l'élément 34 de structure simplifie la construction du train arrière roulant. En outre, le train arrière roulant est avantageusement plus léger.  Such an arrangement is advantageously simpler than a cradle architecture as described in the state of the art. The elimination of the cradle and its replacement by the car 32 and the structure element 34 simplifies the construction of the rolling rear axle. In addition, the rolling rear axle is advantageously lighter.
