Abstract

The invention relates to a method of reducing the number of components forming a vehicle body. More specifically, the invention relates to a car body configuration comprising identical elements which are each reproduced several times. Said configuration considerably simplifies the assembly of a vehicle body, providing savings in terms of production method, spare part storage and maintenance. According to the invention, four different body elements are required, namely: one element (1) which is reproduced four times and which forms the front and rear mudguards; one element (2) for the roof and the supports thereof; one element (3) which is reproduced twice and which forms the front hood and the rear boot; and one element which is reproduced either two or four times, depending on whether it is intended for a coupe or a sedan, and which forms the sliding doors. The headlights and the taillights are provided with the same form, as are the front windscreen and the back window. The invention enables manufacturers to produce cars having different forms and lines.

Description

PROCEDE PERMETTANT DE REDUIRE LE NOMBRE D'ELEMENTS CONSTITUTIFS D'UNE CARROSSERIE DE VEHICULE PROCESS FOR REDUCING THE NUMBER OF COMPONENTS OF A VEHICLE BODY
La présente invention concerne une forme de carrosserie comportant des éléments identiques reproduits plusieurs fois chacun pour permettre l'assemblage symétrique d'une carrosserie de voiture, simplifiant considérablement cet assemblage, apportant une économie en procédé de fabrication, en stock de pièces de rechanges et en entretien.The present invention relates to a form of bodywork comprising identical elements reproduced several times each to allow symmetrical assembly of a car bodywork, considerably simplifying this assembly, bringing an economy in the manufacturing process, in stock of spare parts and in interview.
Traditionnellement, suivant qu'il s'agit d'une berline, d'un break, d'un coupé ou d'un modèle dit « 3 portes », la carrosserie d'une automobile est composée de neuf ou onze éléments principaux de formes différentes :Traditionally, depending on whether it is a sedan, a station wagon, a coupe or a model called "3 doors", the body of an automobile is composed of nine or eleven main elements of forms different:
Figure imgf000002_0001
Figure imgf000002_0001
Il faut rajouter à cette liste d'autres éléments qui sont également distincts : les phares avant sont souvent deux modèles de formes différentes, de même que les feux arrières. Si ces éléments ont chacun une forme différente, il faut fabriquer quatre éléments supplémentaires. Même remarque pour le pare-brise et la lunette arrière, qui aujourd'hui sont différents sur chaque modèle. Grâce à cette invention, le même élément peut-être utilisé comme pare-brise ou comme lunette arrière.We must add to this list other elements which are also distinct: the headlights are often two models of different shapes, as are the rear lights. If these elements each have a different shape, four additional elements must be made. Same remark for the windshield and the rear window, which today are different on each model. Thanks to this invention, the same element can be used as a windshield or as a rear window.
De ce fait, la carrosserie actuelle d'une voiture nécessite la fabrication de nombreux éléments de formes différentes, requiert de nombreuses opérations d'assemblage sur la chaîne de production, et oblige à gérer un stock important de pièces de rechange. La présente invention permet 4e réduire de manière significative le nombre d'éléments distincts nécessaire à la fabrication de la carrosserie : elle permet en effet d'utiliser seulement quatre éléments distincts pour la fabrication de la carrosserie :Therefore, the current bodywork of a car requires the manufacture of many elements of different shapes, requires many assembly operations on the production line, and requires managing a large stock of spare parts. The present invention makes it possible to significantly reduce the number of separate elements necessary for the manufacture of the bodywork: it in fact makes it possible to use only four separate elements for the manufacture of the bodywork:
Les dessins annexés illustrent l'invention :The accompanying drawings illustrate the invention:
La figure 1 représente une vue de dessus d'un véhicule utilisant le dispositif de l'inventionFIG. 1 represents a top view of a vehicle using the device of the invention
La figure 2 représente le même véhicule vu de côtéFigure 2 shows the same vehicle seen from the side
La figure 3 représente une vue de « trois-quarts ».Figure 3 shows a "three-quarter view".
En référence à ces dessins, l'invention comporte les éléments suivants : un élément constitutif des ailes avant et arrière (1). Cet élément de carrosserie est donc reproduit quatre fois pour une voiture. un toit (2) et ses supports un élément constitutif du coffre arrière et du capot avant (3) un élément constitutif de porte coulissante (4) reproduite deux ou quatre fois suivant qu'il s'agit d'une berline ou d'un coupé, au lieu des deux ou quatre portes de forme différente sur les modèles actuels.With reference to these drawings, the invention comprises the following elements: a component of the front and rear wings (1). This body element is therefore reproduced four times for a car. a roof (2) and its supports a component of the rear boot and the front cover (3) a component of a sliding door (4) reproduced two or four times depending on whether it is a sedan or a coupe, instead of two or four doors of different shape on current models.
Au total, nous avons quatre éléments principaux distincts de carrosserie.In total, we have four separate main body parts.
Il convient d'ajouter à cela que les phares avant et les feux arrière (5) seront un seul et même élément, tout comme le pare-brise et la lunette arrière (6), ce qui réduit encore le nombre d'éléments distincts à fabriquer. It should be added to this that the headlights and rear lights (5) will be one and the same element, as will the windshield and the rear window (6), which further reduces the number of separate elements to manufacture.
Présentation des quatre éléments de carrosserie principaux :Presentation of the four main bodywork elements:
1. Les ailes (1) : Il s'agit d'un bloc de carrosserie de forme angulaire, qui s'étend de la moitié de la partie avant jusqu'à une partie d'un côté du véhicule, de manière symétrique. Cette pièce identique est donc utilisée quatre fois par voiture. Elle présente sur le côté de la voiture une partie échancrée nécessaire pour placer la roue qu'elle recouvre. Sur la partie symétrique, cette partie échancrée permet de placer la calandre qui aérera le moteur à l'avant, et à l'arrière par exemple une roue de secours et un rangement supplémentaire au coffre arrière.1. The wings (1): It is a body block of angular shape, which extends from half of the front part to a part of one side of the vehicle, symmetrically. This identical part is therefore used four times per car. It has on the side of the car a notched part necessary to place the wheel it covers. On the symmetrical part, this scalloped part makes it possible to place the radiator grille which will ventilate the engine at the front, and at the rear for example a spare wheel and additional storage in the rear boot.
2. Les portes (4) : La porte est coulissante, et est utilisable indifféremment à l'avant ou à l'arrière, à droite ou à gauche du véhicule. Il s'agit d'un seul modèle, qui est dupliqué deux ou quatre fois suivant le type de véhicule, berline ou coupé.2. Doors (4): The door is sliding, and can be used either at the front or at the rear, to the right or to the left of the vehicle. It is a single model, which is duplicated two or four times depending on the type of vehicle, sedan or coupe.
3. Le toit (2) : Cette partie reste similaire aux voitures d'aujourd'hui.3. The roof (2): This part remains similar to today's cars.
4. Le capot avant et le coffre arrière (3) : Il s'agit exactement du même élément, même forme, l'un s'ouvre pour donner accès au moteur, l'autre s'ouvre pour donner accès au coffre.4. The front cover and the rear trunk (3): It is exactly the same element, same shape, one opens to give access to the engine, the other opens to give access to the trunk.
En plus :More :
5. les phares et les feux arrières (5) : Il s'agit d'un seul élément reproduit quatre fois, les phares avant seront en verre transparent, les feux arrières seront rouges.5. headlights and rear lights (5): This is a single element reproduced four times, the front headlights will be made of transparent glass, the rear lights will be red.
6. le pare brise et la lunette arrière (6) seront identiques en forme.6. the windscreen and the rear window (6) will be identical in shape.
Dispositif d'assemblage des ces éléments : ces éléments s'appuient sur un châssis selon le même principe que les voitures d'aujourd'hui. En s'assemblant, ces éléments, qui au total ont quatre formes différentes, permettent de reconstituer une carrosserie entière de voiture.Device for assembling these elements: these elements are based on a chassis according to the same principle as today's cars. When assembled, these elements, which in total have four different shapes, make it possible to reconstruct an entire car body.
Nous soulignons que cette invention permet à des constructeurs de mettre au point des modèles de voitures de formes et de lignes différentes, tout en respectant ce principe d'éléments identiques. We emphasize that this invention allows manufacturers to develop models of cars of different shapes and lines, while respecting this principle of identical elements.
