Description

DESCRIPTION DESCRIPTION
TITRE DE L’INVENTION : Véhicule comportant un châssis avec renfort de coupelle TITLE OF THE INVENTION: Vehicle comprising a chassis with cup reinforcement
[0001 ] La présente invention revendique la priorité de la demande française 2212194 déposée le 23 novembre 2022 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. La présente invention concerne un véhicule qui comporte un châssis sur lequel est fixé un train arrière muni d’une traverse. [0001] The present invention claims the priority of French application 2212194 filed on November 23, 2022, the content of which (text, drawings and claims) is here incorporated by reference. The present invention relates to a vehicle which comprises a chassis on which is fixed a rear axle provided with a crossmember.
[0002] L’invention concerne plus particulièrement un train arrière qui comporte de chaque côté de la traverse un bras de suspension longitudinal comportant, en partie arrière, un moyeu de roue et, en partie avant, une articulation. [0002] The invention relates more particularly to a rear axle which comprises on each side of the crossmember a longitudinal suspension arm comprising, in the rear part, a wheel hub and, in the front part, an articulation.
[0003] L'articulation permet de solidariser la partie avant du bras de suspension sur le châssis. [0003] The articulation makes it possible to secure the front part of the suspension arm to the chassis.
[0004] Le châssis comporte une coupelle de fixation montée sur un support de train arrière relié au châssis. L’articulation est logée en partie dans la coupelle de fixation et comprend des pattes de fixations pour sa fixation sur une partie supérieure de la coupelle de fixation. [0004] The chassis includes a mounting cup mounted on a rear axle support connected to the chassis. The joint is housed partly in the fixing cup and includes fixing lugs for fixing it to an upper part of the fixing cup.
[0005] Les véhicules électriques comprennent des batteries entraînant un surpoids par rapport à un véhicule thermique. [0005] Electric vehicles include batteries resulting in excess weight compared to a thermal vehicle.
[0006] Il en résulte une force plus importante exercée sur la coupelle de fixation qui peut se déformer et entraîner une désolidarisation de l’articulation par rapport à la coupelle de fixation. [0006] This results in a greater force exerted on the fixing cup which can deform and cause the joint to separate from the fixing cup.
[0007] Le but de l’invention est donc de pallier les inconvénients de l’art antérieur en proposant un véhicule qui comporte un châssis muni d’une coupelle de fixation plus résistante. [0007] The aim of the invention is therefore to overcome the drawbacks of the prior art by proposing a vehicle which comprises a chassis provided with a more resistant fixing cup.
[0008] Pour ce faire, l’invention se rapporte ainsi, dans son acceptation la plus large, à un véhicule comportant un châssis sur lequel est fixé un train arrière comprenant une traverse et un bras de suspension de chaque côté de la traverse. Le bras de suspension comporte, en partie arrière, un moyeu de roue et, en partie avant, une articulation permettant de solidariser la partie avant du bras de suspension sur le châssis. L’articulation est fixée sur une coupelle de fixation montée sur un support de train arrière relié au châssis. [0009] Selon l’invention, le véhicule comprend un renfort de coupelle positionné entre la coupelle de fixation et le support de train arrière. [0008] To do this, the invention thus relates, in its broadest acceptance, to a vehicle comprising a chassis on which is fixed a rear axle comprising a crossmember and a suspension arm on each side of the crossmember. The suspension arm comprises, in the rear part, a wheel hub and, in the front part, a joint allowing the front part of the suspension arm to be secured to the chassis. The joint is fixed on a mounting cup mounted on a rear axle support connected to the chassis. [0009] According to the invention, the vehicle comprises a cup reinforcement positioned between the fixing cup and the rear axle support.
[0010] L’invention fournit ainsi un véhicule qui comporte un châssis muni d’une coupelle de fixation plus résistante. [0010] The invention thus provides a vehicle which comprises a chassis provided with a more resistant fixing cup.
[0011 ] Le renfort de coupelle évite la déformation de la coupelle de fixation et évite à l’articulation de se désolidariser de la coupelle de fixation. [0011] The cup reinforcement prevents deformation of the fixing cup and prevents the joint from separating from the fixing cup.
[0012] Selon une variante, la coupelle de fixation comprend un fond creux comprenant une ouverture dans laquelle est logée partiellement l’articulation. Le renfort de coupelle comprend un orifice dans lequel le fond creux est partiellement logé. [0012] According to a variant, the fixing cup comprises a hollow bottom comprising an opening in which the joint is partially housed. The cup reinforcement comprises an orifice in which the hollow bottom is partially housed.
[0013] Cette configuration permet de renforcer davantage la coupelle de fixation et surtout le fond creux. [0013] This configuration makes it possible to further strengthen the fixing cup and especially the hollow bottom.
[0014] Selon une autre variante, l’orifice du renfort de coupelle est délimité par une première bordure périphérique entourant le fond creux de la coupelle de fixation. According to another variant, the orifice of the cup reinforcement is delimited by a first peripheral border surrounding the hollow bottom of the fixing cup.
[0015] Selon une autre variante, le renfort de coupelle est soudé à la coupelle de fixation. [0015] According to another variant, the cup reinforcement is welded to the fixing cup.
[0016] Selon une autre variante, l’ouverture du fond creux de la coupelle de fixation est délimitée par une deuxième bordure périphérique. La première bordure périphérique du renfort de coupelle est soudée à la deuxième bordure périphérique de la coupelle de fixation à une première extrémité du renfort de coupelle et à une deuxième extrémité du renfort de coupelle, opposée à la première extrémité. [0016] According to another variant, the opening of the hollow bottom of the fixing cup is delimited by a second peripheral border. The first peripheral edge of the cup reinforcement is welded to the second peripheral edge of the fixing cup at a first end of the cup reinforcement and at a second end of the cup reinforcement, opposite the first end.
[0017] Deux zones de soudure suffisent pour assurer une fixation optimisée entre le renfort de coupelle et la coupelle de fixation. La limitation des zones de soudure permet de réduire le temps de fabrication. [0017] Two weld zones are sufficient to ensure optimized fixing between the cup reinforcement and the fixing cup. Limiting the weld zones reduces manufacturing time.
[0018] Selon une autre variante, la première bordure périphérique comprend une bordure arrière longeant une face interne du fond creux. La bordure arrière est positionnée à la première extrémité du renfort de coupelle. La première bordure périphérique comprend une première bordure latérale longeant une première paroi latérale du fond creux et une deuxième bordure latérale longeant une deuxième paroi latérale du fond creux. La première bordure latérale et la deuxième bordure latérale sont reliées par une bordure avant longeant une paroi avant du fond creux. According to another variant, the first peripheral edge comprises a rear edge running along an internal face of the hollow bottom. The rear edge is positioned at the first end of the cup reinforcement. The first peripheral edge comprises a first side edge running along a first side wall of the hollow bottom and a second side edge running along a second side wall of the hollow bottom. The first one side border and the second side border are connected by a front border running along a front wall of the hollow bottom.
[0019] Le renfort de coupelle entoure entièrement le fond creux, assurant une grande solidité à la coupelle de fixation. [0019] The cup reinforcement completely surrounds the hollow bottom, ensuring great strength to the fixing cup.
[0020] Selon une autre variante, la bordure arrière du renfort de coupelle est fixée à une bordure arrière de la deuxième bordure périphérique de la coupelle de fixation. La deuxième bordure latérale et la bordure avant de la première bordure périphérique du renfort de coupelle sont reliées à un premier repli relié à un deuxième repli. Les replis sont positionnés à la deuxième extrémité du renfort de coupelle. Le premier repli est soudé à une première bordure avant de la deuxième bordure périphérique de la coupelle de fixation. [0021 ] Selon une autre variante, le premier repli est perpendiculaire à la première bordure latérale et s’étend vers la première bordure avant de la deuxième bordure périphérique de la coupelle de fixation. Le deuxième repli est perpendiculaire au premier repli et s’étend vers une direction opposée au fond creux. According to another variant, the rear edge of the cup reinforcement is fixed to a rear edge of the second peripheral edge of the fixing cup. The second side edge and the front edge of the first peripheral edge of the cup reinforcement are connected to a first fold connected to a second fold. The folds are positioned at the second end of the cup reinforcement. The first fold is welded to a first front edge of the second peripheral edge of the fixing cup. [0021] According to another variant, the first fold is perpendicular to the first side edge and extends towards the first front edge of the second peripheral edge of the fixing cup. The second fold is perpendicular to the first fold and extends in a direction opposite the hollow bottom.
[0022] Selon une autre variante, la bordure arrière de la première bordure périphérique du renfort de coupelle est inclinée par rapport à la première bordure latérale et à la deuxième bordure latérale de la première bordure périphérique. According to another variant, the rear edge of the first peripheral edge of the cup reinforcement is inclined relative to the first side edge and the second side edge of the first peripheral edge.
[0023] Les replis et cette inclinaison permettent au renfort de coupelle d’épouser la forme du fond creux, assurant un renfort optimisé. [0023] The folds and this inclination allow the cup reinforcement to match the shape of the hollow bottom, ensuring optimized reinforcement.
[0024] Selon une autre variante, le renfort de coupelle est fixé sur le support de train arrière. According to another variant, the cup reinforcement is fixed on the rear axle support.
[0025] Ceci assure le maintien de l’articulation sur le châssis. [0025] This ensures that the articulation is maintained on the chassis.
[0026] On décrira ci-après, à titre d’exemples non limitatifs, des formes d’exécution de la présente invention, en référence aux figures annexées sur lesquelles : [0026] We will describe below, by way of non-limiting examples, embodiments of the present invention, with reference to the appended figures in which:
