Title (EN) ULTRA-LIGHT ROAD VEHICLE
(FR) VEHICULE ROUTIER ULTRA-LEGER
Abstract:
(EN) An ultra-light road vehicle such as a so-called 'town car', particularly an electrically powered one, wherein the weight of the basic construction is minimised so that the vehicle may be powered by batteries while having a standard degree of autonomy for the class of vehicles in question, and the space requirement of said vehicle is reduced for easier parking. For this purpose, said vehicle comprises a chassis (9) with a central hollow beam (12) consisting of an extruded profile section made of a lightweight material and forming a housing for batteries (52) and a driving engine (28), a body (8) consisting of a separate sealed hollow assembly mounted on the chassis, and two steerable wheels (17, 18) at the front and a drive wheel (15) at the back connected to the chassis via suspensions. The rear wheel (15) is mounted on pivotable arms (27) so that the vehicle can be converted from a normal position to a shortened position in which the wheel base is reduced. The pivotable arms (27) are substantially aligned with the central beam (12) when the vehicle is in the normal position, and at an angle thereto when the vehicle is in the shortened position.
(FR) La présente invention concerne un véhicule routier ultra-léger, notamment un véhicule du type appelé 'voiture de ville', en particulier à propulsion électrique, conçu de manière à alléger au maximum sa structure de base pour qu'il puisse être entraîné par des accumulateurs en ayant une autonomie normale pour ce genre de véhicule et à avoir un encombrement réduit pour le stationnement. A cet effet il comporte un châssis (9) formé par une poutre centrale creuse (12) constituée par un profilé extrudé en un matériau léger et servant de logement à des accumulateurs (52) et au moteur de propulsion (28), un habitacle (8) réalisé en corps creux hermétiquement fermé indépendant adapté sur ce châssis, deux roues directrices (17, 18) situées à l'avant et une roue motrice (15) située à l'arrière (15), montées au moyen de suspensions à ce châssis. Le montage de la roue arrière (15) par des branches pivotantes (27) permet au véhicule de prendre une position normale et une position raccourcie qui diminue son empattement, ces branches pivotantes (27) étant disposées sensiblement dans le prolongement de la poutre centrale (12) lorsque le véhicule est dans sa position normale, et inclinées par rapport à cette poutre lorsque le véhicule est dans sa position raccourcie.
