Description

Ensemble moyeu-roue de véhicule automobile
La présente invention concerne un ensemble moyeu-roue de véhicule automobile.Motor vehicle wheel-hub assembly
The present invention relates to a hub-wheel assembly of a motor vehicle.

Dans les ensembles moyeu-roue connus jusqu'à ce jour, l'assemblage de la roue, et en particulier de la jante de celle-ci, avec le moyeu est normalement réalisé en ménageant par découpage, dans la partie centrale de la jante, un trou axial traversant pouvant recevoir avec des tolérances appropriées un appendice tubulaire de centrage de diamètre relativement grand.In the hub-wheel assemblies known to date, the assembly of the wheel, and in particular of the rim thereof, with the hub is normally carried out by cutting, in the central part of the rim, an axial through hole which can receive, with appropriate tolerances, a tubular centering appendage of relatively large diameter.

Dans le but de permettre un centrage facile et commode de la jante sur le moyeu, cet appendice fait saillie d'une certaine longueur par rapport au moyeu lui-meme et présente normalement un poids qui, meme s'il n'est pas considérable, concourt toutefois à augmenter les masses non suspendues du véhicule, avec des effets négatifs sur la tenue de route et sur le confort de marche de celui-ci.In order to allow easy and convenient centering of the rim on the hub, this appendage projects a certain length relative to the hub itself and normally has a weight which, even if it is not considerable, however, contributes to increasing the unsprung masses of the vehicle, with negative effects on the handling and the walking comfort thereof.

Le but de la présente invention est d'éviter au moins en partie l'inconvénient exposé ci-dessus en réduisant au minimum la masse des parties assurant l'assemblage entre le moyeu d'un véhicule automobile et la roue correspondante. The object of the present invention is to avoid at least in part the drawback explained above by minimizing the mass of the parts ensuring the assembly between the hub of a motor vehicle and the corresponding wheel.

Ce but est atteint selon l'invention grâce à un ensemble moyeu-roue de véhicule automobile comprenant une roue munie d1une jante centrale et un moyeu de support de la roue, cette dernière étant solidarisée à un élément de support monté rotatif sur ledit moyeu, caractérisé en ce que ledit élément de support rotatif est muni d'une cavité extérieure limitée par une surface cylindrique coaxiale audit moyeu, laditejante étant munie d'un trou traversant central et axial, dont la périphérie est repliée en direction axiale pour former un appendice cylindrique qui s'engage dans ladite cavité et présente une surface extérieure coopérant avec ladite surface cylindrique.This object is achieved according to the invention thanks to a hub-wheel assembly of a motor vehicle comprising a wheel provided with a central rim and a wheel support hub, the latter being secured to a support element rotatably mounted on said hub, characterized in that said rotary support member is provided with an outer cavity bounded by a cylindrical surface coaxial with said hub, said rim being provided with a central and axial through hole, the periphery of which is folded in an axial direction to form a cylindrical appendage which engages in said cavity and has an outer surface cooperating with said cylindrical surface.

D'autres caractéristiques et avantages de l'invention ressortiront de la description ci-après et du dessin annexé, qui représente partiellement un mode de réalisation non limitatif, en coupe axiale partielle et avec des parties arrachées pour la clarte.Other characteristics and advantages of the invention will emerge from the description below and from the appended drawing, which partially represents a nonlimiting embodiment, in partial axial section and with parts cut away for clarity.

Dans la figure annexée, la référence 1 désigne un ensemble moyeu-roue s'étendant sur le côté d'un châssis 2 de véhicule automobile et comprenant un moyeu 3 et une roue 4. Le moyeu 3 comprend un arbre cylindrique 5 muni à une extrémité d'une bride 6, laquelle est assemblée par l'intermédiaire de vis 7 soit au chassies 2, soit à une paroi de fond 8 d'un corps en godet 9 constituant la partie fixe d'un frein 10 interposé entre la roue 4 et le moyeu 3. L'arbre 5 s'étend à travers la paroi 8 et supporte, à l'intérieur du corps en godet 91et avec l'interposition d'un roulement 11, un manchon 12 de forme cylindrique, lequel est muni à son extrémité extérieure d'une bride circulaire 13.Cette dernière présente une pluralité de trous axiaux traversants 14 (dont un seul est illustré dans la figure), filetés intérieurement et distribués uniformément autour de l'axe de l'arbre 5, et au moins un autre trou fileté 15 de diamètre inférieur à celui des précédents.In the appended figure, the reference 1 designates a hub-wheel assembly extending on the side of a chassis 2 of a motor vehicle and comprising a hub 3 and a wheel 4. The hub 3 comprises a cylindrical shaft 5 provided at one end a flange 6, which is assembled by means of screws 7 either to the casings 2, or to a bottom wall 8 of a bucket body 9 constituting the fixed part of a brake 10 interposed between the wheel 4 and the hub 3. The shaft 5 extends through the wall 8 and supports, inside the bucket body 91 and with the interposition of a bearing 11, a sleeve 12 of cylindrical shape, which is provided at its outer end of a circular flange 13. This latter has a plurality of axial through holes 14 (only one of which is illustrated in the figure), internally threaded and distributed uniformly around the axis of the shaft 5, and at least one another threaded hole 15 of diameter smaller than that of the preceding ones.

A la bride 13 est fixée une paroi de fond 16 d'un corps en godet 17 disposé avec sa concavité dirigée vers celle du corps en godet 9 et constituant une portion rotative du frein 10. La paroi 16 présente au centre un trou axial traversant 18 au travers duquel s'étend une partie filetée d'extrémité 19 de l'arbre 5 portant un écrou 20 qui constitue, par l'intermédiaire d'une rondelle 21, une butée axiale pour une bague intérieure du roulement 11.To the flange 13 is fixed a bottom wall 16 of a bucket body 17 disposed with its concavity directed towards that of the bucket body 9 and constituting a rotary portion of the brake 10. The wall 16 has an axial through hole 18 in the center through which extends a threaded end portion 19 of the shaft 5 carrying a nut 20 which constitutes, by means of a washer 21, an axial stop for an inner ring of the bearing 11.

A l'intérieur de chaque trou 15 est montée une extrémité filetée d'un goujon de repérage 22, lequel traverse un trou 23 percé dans la paroi 16, à laquelle le goujon 22 est fixé par l'intermédiaire d'un écrou 24. Le goujpn 22 présente un bout conique 25 qui s'engage avec un jeu radial dans un trou 26 percé dans une portion centrale d'une jante 27-de la roue 4 pour permettre le positionnement angulaire correct de celui-ci -par rapport à la bride 13 et à la paroi 16.En effet, la jante 27 présente une pluralité de trous 28 en nombre égal à celui des trous 14 et distribués uniformément autour de l'axe d'un trou central 29, le long d'une circonférence de même rayon que celle sur laquelle sont distribués les trous 14; et au positionnement correct de chaque goujon 22 à travers le trou associé 26 correspond l'alignement de chaque trou 28 avec un trou 14 associé et avec un trou 30 correspondant ménagé à travers la paroi 16. Cet alignement est nécessaire pour permettre le montage d'une vis 31 dans chaque trou 28 et les trous 30 et 14 correspondants pour assembler la roue 4 au moyeu 3.Inside each hole 15 is mounted a threaded end of a locating stud 22, which passes through a hole 23 drilled in the wall 16, to which the stud 22 is fixed by means of a nut 24. The goujpn 22 has a conical end 25 which engages with a radial clearance in a hole 26 drilled in a central portion of a rim 27-of the wheel 4 to allow the correct angular positioning thereof-relative to the flange 13 and to the wall 16. Indeed, the rim 27 has a plurality of holes 28 in number equal to that of the holes 14 and distributed uniformly around the axis of a central hole 29, along a circumference of the same radius as that on which the holes 14 are distributed; and to the correct positioning of each stud 22 through the associated hole 26 corresponds the alignment of each hole 28 with an associated hole 14 and with a corresponding hole 30 formed through the wall 16. This alignment is necessary to allow the mounting of a screw 31 in each hole 28 and the corresponding holes 30 and 14 to assemble the wheel 4 to the hub 3.

Pendant le montage, le centrage axial de la roue 4 par rapport au moyeu 3 est assuré par la présence, sur la jante 27, d'un appendice cylindrique 32 obtenu en repliant en direction axiale la partie de la jante 27 qui entoure le trou 29. Le diamètre extérieur de l'appendice 32 est sensiblement égal, aux tolérances près, au diamètre intérieur du trou 18, lequel définit une cavité de centrage dont la surface cylindrique intérieure 33 coopère avec la surface extérieure de l'appendice 32 pour assurer la coaxialité de la roue 4 et du moyeu 3.During assembly, the axial centering of the wheel 4 relative to the hub 3 is ensured by the presence, on the rim 27, of a cylindrical appendage 32 obtained by folding in the axial direction the part of the rim 27 which surrounds the hole 29 The outside diameter of the appendage 32 is substantially equal, to within tolerances, to the inside diameter of the hole 18, which defines a centering cavity whose inner cylindrical surface 33 cooperates with the outside surface of the appendage 32 to ensure coaxiality wheel 4 and hub 3.

Bien que dans l'exemple représenté la cavité de centrage présente la forme d'un trou traversant la portion rotative 17 du frein 10, il est évident que la cavité de centrage peut présenter une forme différente de celle d'un trou-traversant.Although in the example shown the centering cavity has the shape of a hole passing through the rotary portion 17 of the brake 10, it is obvious that the centering cavity may have a shape different from that of a through-hole.

Par exemple, cette cavité pourrait avoir la forme d'une rainure annulaire frontale apte à recevoir l'extrémité de l'appendice 32 et à coopérer avec la surface extérieure de celle-ci. For example, this cavity could have the shape of a front annular groove capable of receiving the end of the appendage 32 and of cooperating with the outer surface of the latter.
