Abstract

The rear wheel and axle structure for an electric vehicle includes wheels (1) attached to respective half axles (3). The axles are attached via the suspension to the body of the vehicle. The floor of the vehicle drops below the level of the axle, so that on either side of a central tunnel (5) there are similar wells (6). The central tunnel provides some support for the inner ends of the half axles. The two wells provide a secure housing for the accumulators which provide the power to electric motors driving the vehicle. In view of their considerable weight the secure low position is a suitable location for the accumulators avoiding bringing the batteries near to the occupants of the vehicle.

Description

La présente invention concerne un agencement de véhicule a propulsion électrique utilisant, comme source d'énergie, des batteries d'accumulateurs. The present invention relates to an electrically propelled vehicle arrangement using, as an energy source, storage batteries.

On sait que, sur ce genre de véhicule, il est essentiel que les batteries, dont le poids est important, soient fermement maintenues pour éviter qu'à l'occasion d'un choc elles soient projetées sur les occupants. Ceci conduit â des renforcements importants de structure entrainant une augmentation du poids et, par conséquent, de la consommation, donc une diminution de l'autonomie du véhicule, à batteries égales. We know that, on this type of vehicle, it is essential that the batteries, whose weight is important, be firmly held to avoid that during an impact they are thrown on the occupants. This leads to significant structural reinforcements resulting in an increase in weight and, consequently, in consumption, therefore a decrease in the autonomy of the vehicle, for equal batteries.

L'invention propose une disposition particulièrement simple permettant d'assurer une retenue efficace des batteries en utilisant les éléments fonctionnels de la suspension du véhicule. The invention proposes a particularly simple arrangement making it possible to ensure effective retention of the batteries by using the functional elements of the vehicle suspension.

L'invention concerne donc un agencement de véhicule muni de batteries d'accumulateurs de traction disposées sur un plancher arrière, chaque roue arrière étant portée par un bras tiré relié à une traverse d'essieu. The invention therefore relates to a vehicle arrangement fitted with traction storage batteries arranged on a rear floor, each rear wheel being carried by a pulled arm connected to an axle cross member.

Cet agencement est caractérisé en ce que ledit plancher est situé, par rapport au sol, à un niveau inférieur à celui de la traverse d'essieu, de sorte que cette dernière sert de butée, vers l'avant, pour les batteries d'accumulateurs. This arrangement is characterized in that said floor is located, relative to the ground, at a level lower than that of the axle cross member, so that the latter serves as a stop, forwards, for storage batteries .

Un exemple de réalisation fait l'objet de la description qui suit, en référence aux dessins joints dans lesquels
- la Fig.1 est une vue de dessus partielle de l'arrière d'un véhicule;
- la Fig.2 en est une vue partielle en élévation;
- la Fig.3 est une coupe transversale suivant la ligne 3-3 de la Fig.2.An exemplary embodiment is the subject of the following description, with reference to the accompanying drawings in which
- Fig.1 is a partial top view of the rear of a vehicle;
- Fig.2 is a partial view in elevation;
- Fig.3 is a cross section along line 3-3 of Fig.2.

Sur le véhicule représenté partiellement sur les Fig., chaque roue arrière 1 est portée par un bras tiré 2 solidaire d'une demi-traverse d'essieu 3. Cette dernière est articulée élastiquement, à chacune de ses extrémités, d'une part sur un longeron 4, d'autre part sur un tunnel longitudinal central 5 disposé dans l'axe du véhicule. On the vehicle partially shown in Figs, each rear wheel 1 is carried by a pulled arm 2 secured to an axle half-cross member 3. The latter is articulated elastically, at each of its ends, on the one hand on a spar 4, on the other hand on a central longitudinal tunnel 5 disposed in the axis of the vehicle.

De part et d'autre du tunnel 5 s'étend un plancher arrière 6 sur lequel sont posées des batteries d'accumulateurs 7 qui fournissent le courant pour un moteur électrique de traction, non représenté. Le plancher 6 est situé à un niveau inférieur à celui des deux demi-traverses d'essieu, de sorte que celles-ci servent de butée, vers l'avant, pour les batteries 7. On either side of the tunnel 5 extends a rear floor 6 on which are placed accumulator batteries 7 which supply the current for an electric traction motor, not shown. The floor 6 is located at a level lower than that of the two axle half-crosspieces, so that these serve as a stop, forwards, for the batteries 7.

Le plancher délimite avec le tunnel 5, deux compartiments pour les batteries 7 symétriques par rapport au-tunnel 5. The floor delimits with the tunnel 5, two compartments for the batteries 7 symmetrical with respect to the tunnel 5.

Grâce à cette disposition, ce sont les éléments fonctionnels de la suspension qui servent à retenir les batteries, interdisant leur projection vers l'habitacle en cas de choc. On voit que ce résultat est obtenu par des moyens particulièrement simples ne nécessitant aucun renforcement de la structure, ce qui permet un gain de poids appréciable. Thanks to this arrangement, it is the functional elements of the suspension which serve to retain the batteries, preventing their projection towards the passenger compartment in the event of an impact. We see that this result is obtained by particularly simple means requiring no strengthening of the structure, which allows a significant weight gain.

Dans l'exemple représenté, on a supposé que chaque bras 2 était solidaire d'une demi-traversed'essieu
3. I1 va de soi qu'une disposition similaire pourrait être adoptée si les deux bras arrière étaient solidaires d'une même traverse d'essieu ou articulés sur une même traverse d'essieu. In the example shown, it has been assumed that each arm 2 was integral with a half-axle beam
3. It goes without saying that a similar arrangement could be adopted if the two rear arms were integral with the same axle cross member or articulated on the same axle cross member.
