Abstract

The wheel unit comprises a wheel (1) fitted with a hub (10). A pivot suspension (2) has a shaft (20) drilled with a cylindrical housing (21) in which the wheel hub is engaged. The pivot shaft is crimped onto a roller bearing (3) interposed between the wheel and the housing.

Description

La présente invention concerne, de façon générale, un dispositif de train roulant du type de ceux qui sont utilisés sur les véhicules à moteur. The present invention relates generally to a rolling gear device of the type of those used on motor vehicles.

Plus précisément, l'invention concerne un dispositif de train roulant comprenant une roue équipée d'un moyeu, un pivot de suspension présentant un fiât perce d'un logement sensiblement cylindrique dans lequel est engagé le moyeu de la roue, et un palier de roulement interposé entre le moyeu de la roue et le logement. More specifically, the invention relates to a rolling gear device comprising a wheel equipped with a hub, a suspension pivot having a pierced fiber of a substantially cylindrical housing in which is engaged the hub of the wheel, and a rolling bearing interposed between the hub of the wheel and the housing.

Bien que de tels dispositifs soient depuis longtemps utilisés sur tous les véhicules automobiles, et bien qu'ils mettent en oeuvre des solutions multiples, la conception de ces dispositifs reste subordonnée à la résolution de différents compromis, notamment techniques et économiques. Although such devices have long been used on all motor vehicles, and although they implement multiple solutions, the design of these devices remains subject to the resolution of different compromises, including technical and economic.

Selon une solution très répandue, le palier roulement peut être maintenu dans le logement, suivant une direction axiale, grâce à un segment d'arrêt circlips. According to a widespread solution, the rolling bearing can be maintained in the housing, in an axial direction, by means of a circlip stop segment.

Outre le fait qu'elle est relativement onéreuse cette solution ne permet pas de réduire le jeu axial du palier de roulement jusqu'à faire disparaître les risques de claquement mécanique du montage, ni les risques de frottement résiduel au niveau du frein porté par roue correspondante. In addition to the fact that it is relatively expensive this solution does not reduce the axial play of the rolling bearing to eliminate the risk of mechanical slamming of the assembly, nor the risk of residual friction at the brake wheel carried corresponding .

Dans le cas d'un pivot en aluminium, une voie possible consiste à utiliser la solution précédemment décrite, complétée par l'emploi d'un insert permettant d'éviter le matage du pivot. In the case of an aluminum pivot, a possible way is to use the previously described solution, supplemented by the use of an insert to prevent the matting of the pivot.

Non seulement cette seconde solution entraîne les mêmes risques que la solution précédente, mais elle est de surcroît plus onéreuse encore, dans la mesure où elle exige l'emploi et la mise en place d'un insert. Not only this second solution carries the same risks as the previous solution, but it is also more expensive still, insofar as it requires the use and implementation of an insert.

Une autre solution parfois adoptée dans le cas d'un pivot en aluminium consiste à utiliser un palier de roulement spécifique, vissé sur le pivot. Dans ce cas, le recours à un roulement spécifique non seulement provoque un déversement plus important de la roue, mais constitue en soi une source de coûts supplémentaires. Another solution sometimes adopted in the case of an aluminum pivot is to use a specific bearing, screwed on the pivot. In this case, the use of a specific bearing not only causes a larger spill of the wheel, but in itself is a source of additional costs.

Dans ce contexte, la présente invention a pour but proposer un dispositif de train roulant dont la conception réalise une meilleure optimisation des compromis économiques et techniques. In this context, the present invention aims to propose a running gear device whose design achieves a better optimization of economic and technical trade-offs.

A cette fin, le dispositif de train roulant de 'invention, par ailleurs conforme à la definition genérique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce que le fût pivot serti sur le palier de roulement. To this end, the rolling gear device of 'invention, also complies with the generic definition given in the preamble above, is essentially characterized in that the shaft pivot crimped on the rolling bearing.

Selon le mode de réalisation préferé de 'invention, le palier de roulement comporte une bague roulement externe présentant une surface externe sensiblement cylindrique, et la bague de roulement externe est calée axialement dans le logement, par sa surface externe, entre un épaulement et un sertissage du fut du pivot. According to the preferred embodiment of the invention, the rolling bearing comprises an outer bearing ring having a substantially cylindrical outer surface, and the outer bearing ring is wedged axially in the housing, by its outer surface, between a shoulder and a crimping. of the pivot.

De façon similaire, le palier de roulement comporte une bague de roulement interne présentant une surface interne sensiblement cylindrique et la bague de roulement interne est avantageusement calée axialement sur le moyeu de la roue, par sa surface interne, entre un épaulement du moyeu et un épaulement d'un axe engagé dans le moyeu de la roue. Similarly, the rolling bearing comprises an inner race having a substantially cylindrical inner surface and the inner race is advantageously axially wedged to the hub of the wheel, by its inner surface, between a shoulder of the hub and a shoulder. an axis engaged in the hub of the wheel.

Le dispositif de l'invention peut ainsi utiliser un palier standard, dans lequel les bagues de roulement interne et externe sont sensiblement de même largeur, y compris dans la cas où le fût du pivot, ou le pivot tout entier, sont en aluminium. The device of the invention can thus use a standard bearing, wherein the inner and outer races are substantially the same width, including in the case where the shaft of the pivot, or the entire pivot, are aluminum.

D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence à la figure unique annexée, qui est une vue en coupe d'un dispositif conforme à l'invention. Other features and advantages of the invention will emerge clearly from the description which is given below, by way of indication and in no way limiting, with reference to the single appended figure, which is a sectional view of a device according to the invention.

Comme le montre cette figure, le dispositif de l'invention comprend essentiellement une roue 1, un pivot de suspension 2, et un palier de roulement 3. As shown in this figure, the device of the invention essentially comprises a wheel 1, a suspension pivot 2, and a rolling bearing 3.

Le pivot 2 présente un fût 20 percé d'un logement indrique 21 dans lequel est engagé moyeu 10 de la roue 1, le palier de roulement 3 étant interposé entre moyeu 10 et le logement 21. The pivot 2 has a shank 20 pierced with an inductive housing 21 in which is engaged hub 10 of the wheel 1, the rolling bearing 3 being interposed between the hub 10 and the housing 21.

Selon un premier aspect de l'invention, le fût 20 pivot est serti sur le palier de roulement 3. According to a first aspect of the invention, the pivot shaft 20 is crimped on the rolling bearing 3.

Plus précisément, le palier de roulement 3 comporte de préférence une bague de roulement externe 31 présentant une surface externe 310 sensiblement indrique et cette bague de roulement externe 31 est calée axialement dans le logement 21 par sa surface externe 310, entre un épaulement 211 fût 20 du pivot un sertissage 212 de ce même fût 20. More specifically, the rolling bearing 3 preferably comprises an outer race 31 having a substantially inductive outer surface 310 and this outer race 31 is axially wedged in the housing 21 by its outer surface 310, between a shoulder 211 which is 20 a crimp a crimp 212 of the same barrel 20.

De même, le palier de roulement 3 comporte avantageusement une bague de roulement interne 32 présentant une surface interne sensiblement indrique, et cette bague de roulement interne 32 est calée axialement sur le moyeu 10 de roue, par sa surface interne 320, entre un épaulement 11 du moyeu et un épaulement 40 de l'axe 4 de la roue, qui est engagé dans le moyeu 10. Similarly, the rolling bearing 3 advantageously comprises an inner race 32 having a substantially inductive inner surface, and this inner race 32 is axially wedged to the wheel hub 10 by its inner surface 320 between a shoulder 11. of the hub and a shoulder 40 of the axis 4 of the wheel, which is engaged in the hub 10.

Le palier utilisé peut ainsi être un palier standard, dans lequel les bagues de roulement interne et externe 32, 31 sont sensiblement de même largeur. The bearing used can thus be a standard bearing, in which the inner and outer races 32, 31 are substantially of the same width.

Dans l'application privilégiée de l'invention, le pivot de suspension 2 est intégralement réalisé en aluminium. In the preferred application of the invention, the suspension pivot 2 is made entirely of aluminum.

Le cas échéant, le pivot peut être conçu de façon que son fût 20 au moins soit en aluminium, ce fût devant en tout cas être réalisé en un matériau suffisamment ductile pour supporter le sertissage. Where appropriate, the pivot may be designed so that its barrel 20 is at least aluminum, it was in any case be made of a sufficiently ductile material to support crimping.
