Description
La présente invention concerne un véhicule qui comporte un écran thermique.The present invention relates to a vehicle that includes a heat shield.
La présente invention concerne plus particulièrement un tel un véhicule qui comporte un moteur et écran thermique adapté pour former une protection thermique au véhicule contre le rayonnement thermique d’une partie dudit moteur, ledit véhicule comportant aussi des éléments de suspension comportant une barre anti-devers avec l’écran thermique qui est en partie positionné en dessous des éléments de suspension.The present invention relates more particularly to such a vehicle which comprises an engine and heat shield adapted to form a thermal protection for the vehicle against the thermal radiation of a part of said engine, said vehicle also comprising suspension elements comprising an anti-roll bar with the heat shield which is partly positioned below the suspension elements.
Le document FR-B1-2975659 divulgue un véhicule qui comporte un moteur et écran thermique adapté pour former une protection thermique au véhicule contre le rayonnement thermique d’une partie dudit moteur, ledit véhicule comportant un écran thermique qui est en partie positionné en dessous des éléments de suspension avec les moyens de fixation avant de l’écran thermique sous les éléments de suspension qui sont formés par des fixations magnétiques.The document FR-B1-2975659 discloses a vehicle which comprises an engine and heat shield adapted to form thermal protection for the vehicle against thermal radiation from a part of said engine, said vehicle comprising a heat shield which is partly positioned below the suspension elements with the front fixing means of the heat shield under the suspension elements which are formed by magnetic fixings.
De telles fixations présentent un coût important et ont un risque important de se détacher en particulier lorsque le véhicule passe dans une profonde flaque d’eau.Such fasteners are expensive and have a high risk of coming loose, especially when the vehicle passes through a deep puddle.
Il est connu par ailleurs de visser l’écran thermique au berceau avant, mais ces deux solutions ne sont pas intéressantes car elles sont dépendantes de la forme du berceau qui dans certains cas n’est pas positionné suffisamment proche de l’écran thermique pour que celui-ci puisse y être solidarisé.It is also known to screw the heat shield to the front cradle, but these two solutions are not interesting because they are dependent on the shape of the cradle which in some cases is not positioned close enough to the heat shield so that this one can be solidarized there.
Rajouter une traverse de fixation pour l’écran thermique coûte trop chère et rajoute une pièce inutilement.Adding a fixing crosspiece for the heat shield is too expensive and adds a part unnecessarily.
Le dispositif selon l’invention permet de remédier à ces inconvénients.The device according to the invention makes it possible to remedy these drawbacks.
Il comporte en effet selon une première caractéristique, un véhicule qui comporte un moteur et un écran thermique adapté pour former une protection thermique au véhicule contre le rayonnement thermique d’une partie du moteur, le véhicule comportant aussi des éléments de suspension comportant une barre anti-devers, tel qu’une partie des moyens de fixation de l’écran thermique sont solidarisés sur la barre anti-devers.It comprises in fact according to a first characteristic, a vehicle which comprises an engine and a heat shield adapted to form a thermal protection for the vehicle against the thermal radiation of a part of the engine, the vehicle also comprising suspension elements comprising an anti- -devers, such that part of the heat shield fixing means are secured to the anti-roll bar.
Selon une première caractéristique de l’invention, les moyens de fixation comportent deux paliers concentriques positionnés autour d’une partie cylindrique de la barre anti-devers, un premier palier en plastique rigide ou en métal formant un palier extérieur et un second palier en élastomère formant un palier intérieur.According to a first characteristic of the invention, the fixing means comprise two concentric bearings positioned around a cylindrical part of the anti-roll bar, a first bearing made of rigid plastic or metal forming an outer bearing and a second bearing made of elastomer forming an interior landing.
Selon une deuxième caractéristique de l’invention, le palier extérieur est formé en deux parties qui forment deux demi-cylindres, le palier intérieur étant formé aussi en deux parties qui forment deux demi-cylindres avec le premier demi-cylindre du palier intérieur qui est surmoulé dans le premier demi-cylindre du palier extérieur et le second demi-cylindre du palier intérieur qui est surmoulé dans le second demi-cylindre du palier extérieur.According to a second feature of the invention, the outer bearing is formed in two parts which form two half-cylinders, the inner bearing also being formed in two parts which form two half-cylinders with the first half-cylinder of the inner bearing which is overmolded in the first half-cylinder of the outer bearing and the second half-cylinder of the inner bearing which is overmolded in the second half-cylinder of the outer bearing.
Selon une troisième caractéristique de l’invention, les deux demi-cylindre du palier extérieur comportent des moyens d’accroche permettant de solidariser ledit premier demi-cylindre audit second demi-cylindre.According to a third characteristic of the invention, the two half-cylinders of the outer bearing comprise attachment means making it possible to secure said first half-cylinder to said second half-cylinder.
Selon une quatrième caractéristique de l’invention, les moyens de fixation comportent une pince déformable qui enserre les deux paliers, la pince étant aussi solidaire de l’écran thermique.According to a fourth characteristic of the invention, the fixing means comprise a deformable clamp which encloses the two bearings, the clamp also being integral with the heat shield.

Selon une septième caractéristique de l’invention, la pince est réalisée dans une matière plastique rigide résistante à la chaleur ou en métal.According to a seventh characteristic of the invention, the clamp is made of a rigid heat-resistant plastic material or of metal.
La présente invention concerne aussi un ensemble de fixation pour un tel véhicule qui comporte deux palier concentriques formés par un palier intérieur en élastomère surmoulé dans un palier extérieur rigide et d’une pince qui enserre lesdits paliers, les deux paliers étant adaptés pour entourer une partie cylindrique d’une barre anti-devers et la pince comportant une partie adaptée pour être solidarisée sur un écran thermique.The present invention also relates to a fixing assembly for such a vehicle which comprises two concentric bearings formed by an inner bearing in elastomer overmolded in a rigid outer bearing and a clamp which encloses said bearings, the two bearings being adapted to surround a part cylindrical part of an anti-roll bar and the clamp comprising a part adapted to be secured to a heat shield.
Les dessins annexés illustrent l’invention :The accompanying drawings illustrate the invention:
En référence à ces dessins, le véhicule comporte un moteur et écran thermique 1 adapté pour former une protection thermique au véhicule contre le rayonnement thermique d’une partie du moteur, en particulier d’une partie du système d’échappement du moteur.With reference to these drawings, the vehicle comprises an engine and heat shield 1 adapted to form a thermal protection for the vehicle against the thermal radiation from a part of the engine, in particular from a part of the engine exhaust system.
Le véhicule comporte aussi des éléments de suspension qui comportent une barre anti-devers 2 qui est positionnée proche de l’écran thermique 1.The vehicle also comprises suspension elements which comprise an anti-roll bar 2 which is positioned close to the heat shield 1.
L’écran thermique 1 est solidarisé sous le véhicule par différents moyens de fixations, des moyens fixations centrales et arrières qui sont solidarisés sous le plancher de l’habitacle du véhicule pour solidariser la partie centrale et la partie arrière de l’écran thermique 1 sous le véhicule et des moyens de fixation 3 avant de l’écran thermique qui sont solidarisés sur la barre anti-devers 2.The heat shield 1 is secured under the vehicle by various fixing means, central and rear fixing means which are secured under the floor of the passenger compartment of the vehicle to secure the central part and the rear part of the heat screen 1 under the vehicle and front fixing means 3 of the heat shield which are secured to the anti-roll bar 2.
Les moyens de fixation 3 avant comportent deux paliers concentriques positionnés autour d’une partie cylindrique 21 de la barre anti-devers 2 avec un premier palier 31 rigide qui forme un palier extérieur et un second palier 32 en élastomère qui forme un palier intérieur.The front fastening means 3 comprise two concentric bearings positioned around a cylindrical part 21 of the anti-roll bar 2 with a first rigid bearing 31 which forms an outer bearing and a second elastomer bearing 32 which forms an inner bearing.
Le palier extérieur 31 est généralement formé en plastique rigide ou en métal et est constitué de deux demi-cylindres, le palier intérieur 32 étant aussi formé en deux demi-cylindres, un premier demi-cylindres 33 du palier intérieur 32 étant surmoulée dans un premier demi-cylindres 34 du palier extérieur 31 et un second demi-cylindres 35 du palier intérieur 32 étant surmoulée dans un second demi-cylindres 36 du palier extérieur 31.The outer bearing 31 is generally formed of rigid plastic or metal and consists of two half-cylinders, the inner bearing 32 also being formed of two half-cylinders, a first half-cylinder 33 of the inner bearing 32 being molded in a first half-cylinders 34 of the outer bearing 31 and a second half-cylinder 35 of the inner bearing 32 being molded into a second half-cylinder 36 of the outer bearing 31.
Chacun des deux demi-cylindres du palier extérieur 31 comportent des moyens d’accroche 37 qui permettent de solidariser le premier demi-cylindre 34 au second demi-cylindre 36 autour de la barre anti-devers 2.Each of the two half-cylinders of the outer bearing 31 comprise attachment means 37 which make it possible to secure the first half-cylinder 34 to the second half-cylinder 36 around the anti-roll bar 2.
Les moyens de fixation 3 comportent aussi une pince 4 déformable qui enserre l’ensemble des deux paliers.The fixing means 3 also comprise a deformable clamp 4 which encloses all of the two bearings.
La pince 4 est solidaire de l’écran thermique 1 aux moyens de points de soudure ou par un ou plusieurs rivets et cela en fonction de la matière dans laquelle est réalisée la pince, qu’elle soit en plastique rigide ou en métal.Clamp 4 is secured to heat shield 1 by means of spot welds or by one or more rivets, depending on the material from which the clamp is made, whether it is rigid plastic or metal.
Du fait de la proximité de la pince 4 avec l’écran thermique 1, la pince est soumise à de fortes contraintes thermique qui restent compatibles avec une pince 4 réalisée dans une matière plastique adaptée.Due to the proximity of the clamp 4 with the heat shield 1, the clamp is subjected to high thermal stresses which remain compatible with a clamp 4 made of a suitable plastic material.
Le palier extérieur 31 comporte des bordures latérales 38 adaptées pour bloquer latérale la pince 4.The outer bearing 31 has side edges 38 adapted to block the clamp 4 laterally.
La pince 4 comporte, au niveau de ces extrémités libres, des parties relevées 41 facilitant le positionnement et le retrait de la pince 4 du palier pour fixer ou retirer plus facilement l’écran thermique 1 du véhicule.The clamp 4 comprises, at these free ends, raised parts 41 facilitating the positioning and removal of the clamp 4 from the bearing in order to fix or remove the heat shield 1 from the vehicle more easily.
Lors du fonctionnement du véhicule, la barre anti-devers 2 à un mouvement de rotation, le palier du fait du palier intérieur 32 en élastomère a tendance à suivre ce mouvement de rotation, la pince 4 qui est positionnée autour du palier peut tourner librement sans transmettre de contraintes particulières sur l’écran thermique 1.During operation of the vehicle, the anti-roll bar 2 has a rotational movement, the bearing due to the inner bearing 32 in elastomer tends to follow this rotational movement, the clamp 4 which is positioned around the bearing can rotate freely without transmit specific stresses to the heat shield 1.
Le palier intérieur 32 en élastomère permet d’absorber par déformation des déplacements verticaux de +/- 1mm de la barre anti-devers 2 lors du fonctionnement du véhicule.The inner elastomer bearing 32 makes it possible to absorb, by deformation, vertical displacements of +/- 1 mm of the anti-roll bar 2 during operation of the vehicle.
Le palier intérieur 32 en élastomère permet aussi d’adapter simplement le palier au diamètre de la barre anti-devers 2 en modifiant l’épaisseur du pallier intérieur 32 sans modifier le pallier extérieur 31 et sans modifier la pince 4.The inner elastomer bearing 32 also makes it possible to simply adapt the bearing to the diameter of the anti-roll bar 2 by modifying the thickness of the inner bearing 32 without modifying the outer bearing 31 and without modifying the clamp 4.
