Description

Essieu de véhicule automobile comprenant des moyens de fixation d’un roulement de roue à la tête d’essieuMotor vehicle axle comprising means for fixing a wheel bearing to the axle head

La présente invention concerne le domaine des véhicules automobiles, et plus particulièrement, les trains arrière de véhicules automobiles.The present invention relates to the field of motor vehicles, and more particularly, the rear axles of motor vehicles.

De manière générale, un train arrière comprend un essieu s’étendant transversalement au véhicule automobile et reliant deux roues par l’intermédiaire d’un roulement de roue fixé sur une tête d’essieu solidaire d’un bras d’essieu fixé à chacune des extrémités de l’essieu.In general, a rear axle comprises an axle extending transversely to the motor vehicle and connecting two wheels by means of a wheel bearing fixed on an axle head secured to an axle arm fixed to each of the axle ends.

De nos jours, la fixation du roulement de roue se fait par des vis de fixation sur la tête d’essieu, implantées à l’intérieur de renforts avant et arrière fixés sur le bras d’essieu et formant avec la tête d’essieu une pièce de fixation en forme de U.Nowadays, the wheel bearing is fixed by fixing screws on the axle head, located inside front and rear reinforcements fixed on the axle arm and forming with the axle head a U-shaped mounting piece.

On peut à cet égard se référer au document US 2014151973 dans lequel les perçages pour la fixation du roulement de roue sont situés entre les deux renforts.In this regard, reference can be made to document US 2014151973 in which the holes for fixing the wheel bearing are located between the two reinforcements.

Toutefois, un tel agencement ne permet pas de remplacer le roulement à roue existant par un roulement à roue de plus grand diamètre sans modifier le bras d’essieu.However, such an arrangement does not allow the existing wheel bearing to be replaced by a larger diameter wheel bearing without modifying the axle arm.

Il existe donc un besoin de proposer une solution pour la fixation d’un roulement à roue de grand diamètre sur une tête d’essieu d’un essieu existant.There is therefore a need to propose a solution for fixing a large-diameter wheel bearing on an axle head of an existing axle.

L’objectif de l’invention est donc de pallier ces inconvénients et de proposer un système permettant la fixation d’un roulement à roue de grand diamètre sur une tête d’essieu tout en conservant l’essieu existant.The objective of the invention is therefore to overcome these drawbacks and to propose a system allowing the fixing of a large-diameter wheel bearing on an axle head while retaining the existing axle.

La présente invention a pour objet un essieu de véhicule automobile comprenant au moins un bras d’essieu, au moins une tête d’essieu solidaire dudit bras d’essieu par au moins un premier et un deuxième moyens de renforts. Ladite tête d’essieu comprend au moins deux perçages disposés chacun sur un axe de perçage et destinés chacun à recevoir une vis de fixation d’un roulement de roue, les deux axes de perçage étant parallèles entre eux.The present invention relates to a motor vehicle axle comprising at least one axle arm, at least one axle head secured to said axle arm by at least first and second reinforcement means. Said axle head comprises at least two holes each arranged on a drilling axis and each intended to receive a fixing screw for a wheel bearing, the two drilling axes being parallel to each other.

Le premier moyen de renfort est disposé entre les deux axes de perçages et le deuxième moyen de renfort est disposé au-delà des axes de perçages.The first reinforcement means is arranged between the two drilling axes and the second reinforcement means is disposed beyond the drilling axes.

En d’autres termes le premier axe de perçage se trouve entre le deuxième moyen de renfort et le premier moyen de renfort et le deuxième axe de perçage se trouve à l’extérieur du premier moyen de renfort. On obtient ainsi une alternance de moyen de renfort et d’axe de perçage sur la tête d’essieu.In other words, the first piercing axis is located between the second reinforcing means and the first reinforcing means and the second piercing axis is located outside the first reinforcing means. One thus obtains an alternation of reinforcement means and drilling axis on the axle head.

Ainsi, il est possible de conserver la position d’assemblage des renforts avant et arrière sur le bras d’essieu et de modifier uniquement l’implantation de la tête d’essieu par rapport à ces renforts.Thus, it is possible to keep the assembly position of the front and rear reinforcements on the axle arm and to modify only the location of the axle head with respect to these reinforcements.

Selon un mode de réalisation, la tête d’essieu se présente sous la forme d’une plaque sensiblement plane formant avec les moyens de renforts une tôle en forme de F.According to one embodiment, the axle head is in the form of a substantially flat plate forming with the reinforcing means an F-shaped sheet.

Selon un autre mode de réalisation, la tête d’essieu est réalisée à partir d’une tôle pliée en forme de L comprenant le deuxième moyen de renfort, le premier moyen de renfort étant fixé, par exemple par soudure, à la tête d’essieu pour former une forme en I. Dans cette variante, les premier et deuxième axes de perçage restent disposés sur la tête d’essieu en forme de tôle en L, notamment sur la branche de la tête d’essieu perpendiculaire au deuxième moyen de renfort.According to another embodiment, the axle head is produced from an L-shaped bent sheet comprising the second reinforcement means, the first reinforcement means being fixed, for example by welding, to the head axle to form an I-shape. In this variant, the first and second drilling axes remain arranged on the axle head in the form of an L-shaped sheet, in particular on the branch of the axle head perpendicular to the second reinforcement means. .

Avantageusement, chaque axe de perçage comprend une paire de perçages pour la fixation dudit roulement de roue.Advantageously, each drilling axis comprises a pair of holes for fixing said wheel bearing.

La tête d’essieu peut également comprendre un trou débouchant (26) situé entre les deux axes de perçages.The axle head may also include a through hole (26) located between the two drilling axes.

Chacun des moyens de renforts a, par exemple, la forme d’une équerre et peuvent être fixés respectivement à la tête d’essieu et au bras d’essieu par soudage.Each of the reinforcing means has, for example, the shape of a square and can be fixed respectively to the axle head and the axle arm by welding.

En variante, on pourrait prévoir une fixation par moyens de visseries.Alternatively, one could provide a fixing by means of screws.

Selon un second aspect, l’invention concerne un train arrière de véhicule automobile comprenant un essieu tel que décrit précédemment.According to a second aspect, the invention relates to a rear axle of a motor vehicle comprising an axle as described above.

Selon un troisième aspect, l’invention concerne un véhicule automobile comprenant un train arrière tel que décrit précédemment.According to a third aspect, the invention relates to a motor vehicle comprising a rear axle as described above.

D’autres buts, caractéristiques et avantages de l’invention apparaîtront à la lecture de la description suivante, donnée uniquement à titre d’exemple non limitatif, et faite en référence aux dessins annexés sur lesquels :Other objects, characteristics and advantages of the invention will appear on reading the following description, given solely by way of non-limiting example, and made with reference to the appended drawings in which:

- la figure 1 est une vue en coupe d’une partie d’un essieu d’un véhicule automobile selon l’invention; et- Figure 1 is a sectional view of a portion of an axle of a motor vehicle according to the invention; and

- la figure 2 représente une vue en perspective de la partie d’essieu de la figure 1.- Figure 2 shows a perspective view of the axle part of Figure 1.

Tel qu’illustré sur les figures 1 et 2, une partie d’un essieu, référencé 10 dans son ensemble, est destiné à être intégré dans un train arrière de véhicule automobile.As illustrated in FIGS. 1 and 2, part of an axle, referenced 10 as a whole, is intended to be integrated in a rear axle of a motor vehicle.

La partie d’essieu 10 comprend un bras d’essieu 12, par exemple de forme tubulaire, relié à une extrémité d’un essieu (non représenté), une tête d’essieu 14 solidaire du bras d’essieu par deux moyens de renforts 16, 18.The axle part 10 comprises an axle arm 12, for example of tubular shape, connected to one end of an axle (not shown), an axle head 14 secured to the axle arm by two reinforcing means 16, 18.

Chacun des moyens de renforts 16, 18 a la forme d’une équerre et est fixé respectivement à la tête d’essieu 14 et au bras d’essieu 12 par soudage. En variante, on pourrait prévoir une fixation par moyens de visseries.Each of the reinforcing means 16, 18 has the shape of a square and is fixed respectively to the axle head 14 and to the axle arm 12 by welding. Alternatively, one could provide a fixing by means of screws.

Tel qu’illustré, la tête d’essieu 14 se présente sous la forme d’une plaque sensiblement plane et rectangulaire comportant quatre perçages 20a, 20b ; 22a, 22b, chaque paire de perçages étant disposé sur un axe de perçage Al, A2. Les deux axes de perçages Al, A2 sont parallèles entre eux.As illustrated, the axle head 14 is in the form of a substantially flat and rectangular plate comprising four holes 20a, 20b; 22a, 22b, each pair of bores being arranged on a boring axis A1, A2. The two drilling axes A1, A2 are mutually parallel.

En variante, on pourrait prévoir que la tête d’essieu comprennent un nombre de perçages différent de quatre, par exemple, deux, ou supérieur à quatre, chaque axe de perçage comprenant au moins un perçage.Alternatively, one could provide that the axle head include a number of holes other than four, for example two, or more than four, each drilling axis comprising at least one hole.

Chaque perçage 20a, 20b ; 22a, 22b est destiné à recevoir une vis de fixation (non représentée) afin de fixer un roulement à roue 24.Each hole 20a, 20b; 22a, 22b is intended to receive a fixing screw (not shown) in order to fix a wheel bearing 24.

La tête d’essieu 14 comprend en outre un trou 26 situé entre les deux axes de perçages Al, A2, pour le passage par exemple de capteurs.The axle head 14 further comprises a hole 26 located between the two drilling axes A1, A2, for the passage, for example, of sensors.

Tel qu’illustré, le premier moyen de renfort 16 est disposé entre les deux axes de perçages Al, A2 et le deuxième moyen de renfort 18 est disposé à une extrémité de la tête d’essieu au-delà des axes Al, A2 de perçages. En d’autres termes, le premier axe de perçage Al se trouve entre le deuxième moyen de renfort 18 et le premier moyen de renfort 16 et le deuxième axe de perçage A2 se trouve à l’extérieur du premier moyen de renfort 16.As illustrated, the first reinforcement means 16 is arranged between the two drilling axes A1, A2 and the second reinforcement means 18 is arranged at one end of the axle head beyond the drilling axes A1, A2 . In other words, the first piercing axis A1 is located between the second reinforcing means 18 and the first reinforcing means 16 and the second piercing axis A2 is located outside the first reinforcing means 16.

La tête d’essieu 14 et les moyens de renforts 16, 18 forment ensemble une forme d’une tôle en E.The axle head 14 and the reinforcement means 16, 18 together form a form of an E-sheet.

En variante, on pourrait prévoir que tête d’essieu soit réalisée à partir d’une tôle pliée en forme de L comprenant le deuxième moyen de renfort 18. Le premier moyen de renfort 16 serait alors fixé, par exemple par soudure, à la tête d’essieu pour former une forme en I. Dans cette variante, les premier et deuxième axes de perçage Al, A2 restent disposés sur la tête d’essieu en forme de tôle en L, notamment sur la branche de la tête d’essieu perpendiculaire au deuxième moyen de renfort 18.As a variant, provision could be made for the axle head to be produced from an L-shaped folded sheet comprising the second reinforcement means 18. The first reinforcement means 16 would then be fixed, for example by welding, to the head axle to form an I shape. In this variant, the first and second drilling axes A1, A2 remain disposed on the axle head in the form of an L-shaped sheet, in particular on the branch of the perpendicular axle head the second reinforcement means 18.

Ainsi, grâce à l’invention, on peut fixer sur une tête d’essieu un roulement à roue de grand diamètre tout en conservant un essieu existant. De ce fait, il est possible de conserver la position d’assemblage des renforts avant et arrière sur le bras d’essieu et de modifier uniquement l’implantation de la tête d’essieu par rapport à ces renforts.Thus, thanks to the invention, it is possible to fix a large diameter wheel bearing to an axle head while retaining an existing axle. Therefore, it is possible to keep the assembly position of the front and rear reinforcements on the axle arm and to modify only the location of the axle head with respect to these reinforcements.
