Description

DISPOSITIF DE FIXATION D'UN CHÂSSIS RAPPORTE SUR LA CAISSE D'UN VEHICULE, EN PARTICULIER D'UN CHÂSSIS DE CHAÎNE DE TRACTION SUR LA CAISSE D'UN VEHICULE AUTOMOBILE ELECTRIQUE. DEVICE FOR FASTENING A CHASSIS RELATED TO THE BODY OF A VEHICLE, IN PARTICULAR A CHAIN CHAIN OF TRACTION ON THE BODY OF AN ELECTRIC MOTOR VEHICLE.

La présente invention concerne un dispositif de fixation d'un châssis rapporté sur la caisse d'un véhicule, en particulier d'un châssis de chaîne de traction sur la caisse d'un véhicule automobile électrique. The present invention relates to a device for attaching a frame attached to the body of a vehicle, in particular a traction chain chassis on the body of an electric motor vehicle.

Il est connu qu'une motorisation de véhicule électrique doit être supportée par un châssis intermédiaire, désigné aussi « châssis de la chaîne de traction » dans la suite du texte, de façon à rendre la motorisation indépendante de la caisse du véhicule. Le poids de cette motorisation, fortement augmenté par la présence des batteries notamment, est relativement important et impose, de ce fait, une rigidité maximale des fixations associée à un guidage précis pour la mise en place en usine ou pour les opérations de maintenance. It is known that an electric vehicle engine must be supported by an intermediate frame, also referred to as "chassis of the traction chain" in the rest of the text, so as to make the engine independent of the vehicle body. The weight of this engine, greatly increased by the presence of batteries in particular, is relatively large and therefore imposes a maximum stiffness of the fasteners associated with precise guidance for implementation in the factory or for maintenance operations.

On connaît déjà des dispositifs de fixation par vissage d'une pièce mécanique sur la caisse d'un véhicule. Ainsi, à titre d'exemple, le document EP 0 390 751 B1 décrit un dispositif destiné à fixer au plancher d'une caisse de véhicule automobile une pièce mécanique qui a été préalablement présentée au plancher par-dessous, le plancher présentant un trou pour le vissage par-dessus. Le dispositif comprend les éléments suivants, en combinaison : - un élément de positionnement adapté pour s'engager dans le trou formé dans la caisse, lequel élément de positionnement, d'une part, est constitué par un téton muni d'une tête destinée à être soudée à la pièce mécanique qu'il s'agit de fixer et, d'autre part, possède un trou fileté, - une vis, qui est adaptée pour coopérer avec le trou fileté de l'élément de positionnement et qui possède une 35 tête, et - un manchon, qui possède, d'une part, une première partie de petit diamètre montée coulissante sur la vis, la tête de la vis portant sur son extrémité, et d'autre part, une deuxième partie de plus grand diamètre, adaptée pour s'emboîter sur la surface extérieure de la partie de l'élément de positionnement qui, dans l'état monté, fait saillie à travers le trou de la caisse de manière à faciliter le montage et l'insertion de la vis dans le trou fileté de l'élément de positionnement. Le but de la présente invention est de fournir un dispositif de fixation d'un châssis rapporté sur la caisse d'un véhicule, en particulier d'un châssis de chaîne de traction sur la caisse d'un véhicule automobile électrique, qui permette d'assurer un guidage, un positionnement et une mise en place précis dudit châssis rapporté en garantissant une rigidité maximale des points de fixation vis-à-vis des interfaces existantes. Un autre but de la présente invention est de fournir un tel dispositif, qui soit entièrement accessible depuis le dessous du véhicule. Un autre but de la présente invention est de fournir 20 un tel dispositif, qui permette un gain de masse par rapport aux dispositifs de fixation connus de l'art antérieur. Enfin, c'est également un but de la présente invention de fournir un tel dispositif, qui soit, de manière générale, simple, stable, fiable et économique, en particulier en 25 permettant de faire l'économie d'une fonction supplémentaire de guidage à un autre emplacement du châssis et de la caisse. Pour parvenir à ces buts, la présente invention a pour objet un dispositif de fixation d'un châssis rapporté sur la 30 caisse d'un véhicule, en particulier d'un châssis de chaîne de traction sur la caisse d'un véhicule automobile électrique, et ce dispositif comporte, pour chaque vis de fixation du châssis rapporté sur la caisse du véhicule, les éléments suivants, pris en combinaison : 35 - un centreur mâle, qui est soudé à la caisse et qui comporte un filetage interne pour le vissage de ladite vis de fixation, un centreur femelle, rigide, soudé au châssis rapporté, qui vient co-axialement coiffer le centreur mâle et qui comporte un perçage central pour le passage de ladite vis de fixation. Already known fasteners by screwing a mechanical part on the body of a vehicle. Thus, for example, the document EP 0 390 751 B1 describes a device for attaching to the floor of a motor vehicle body a mechanical part which has been previously presented to the floor from below, the floor having a hole for screwing over. The device comprises the following elements, in combination: - a positioning element adapted to engage in the hole formed in the box, which positioning element, on the one hand, is constituted by a pin provided with a head intended for it is welded to the mechanical part which is to be fixed and, on the other hand, has a threaded hole, - a screw, which is adapted to cooperate with the threaded hole of the positioning element and which has a 35 head, and - a sleeve, which has, on the one hand, a first portion of small diameter slidably mounted on the screw, the head of the screw bearing on its end, and secondly, a second portion of larger diameter , adapted to fit on the outer surface of the portion of the positioning member which, in the mounted state, projects through the hole in the box so as to facilitate mounting and insertion of the screw into the threaded hole of the positioning element ement. The object of the present invention is to provide a device for attaching a frame attached to the body of a vehicle, in particular a traction chain chassis on the body of an electric motor vehicle, which allows provide accurate guidance, positioning and placement of said attached frame ensuring maximum rigidity of the attachment points vis-à-vis the existing interfaces.
