Abstract

The subject of the present invention is a device for supplying pressurised liquid to a brake, which device comprises a supply pipe 5 for the fluid having a deformable curved-over part. According to the invention, this part is located approximately in one plane.

Description

t'alimentation en liquide d'un frein logé sur un élément mobile, tel qu'un bras support de roue, est assurée le plus couramment par l'intermédiaire d'un flexible qui encaisse les mouvements différentiels du bras par rapport à la caisse du véhicule.the supply of liquid to a brake housed on a mobile element, such as a wheel support arm, is most commonly provided by means of a hose which collects the differential movements of the arm relative to the body of the vehicle.

Dans le cas d'un essieu arrière à bras tirés, il est connu par le brevet français 1 409 885 d'assurer l'alimentation par un tuyau qui comporte plusieurs spires centrées sur l'axe de pivotement du bras et qui travaille en torsion lors des mouvements de ce bras. Cette solution supprime le flexible mais nécessite le montage du tuyau autour du tube d'essieu lors de l'assemblage de ce dernier et ce montage est difficilement automatisable.In the case of a rear axle with pulled arms, it is known from French patent 1 409 885 to ensure the supply by a pipe which has several turns centered on the pivot axis of the arm and which works in torsion during movements of this arm. This solution eliminates the flexible but requires the mounting of the pipe around the axle tube during the assembly of the latter and this mounting is difficult to automate.

La présente invention a pour objet un dispositif pour l'alimentation d'un frein en fluide sous pression, qui ne nécessite pas de flexible, pièce chère et dont le montage est difficilement automatisable, et peut être monté sur l'essieu lorsque celui-ci est assemblé, ce montage pouvant éventuellement être réalisé à l'aide d'un robot.The subject of the present invention is a device for supplying a brake with pressurized fluid, which does not require a flexible, expensive part and the mounting of which is difficult to automate, and can be mounted on the axle when the latter is assembled, this assembly possibly being possible using a robot.

Le dispositif selon l'invention, qui comprend un tuyau d'amenée du fluide présentant une partie recourbée déformable, est caractérisé en ce que cette partie se trouve approximativement dans un plan. Cette partie déformable est avantageusement formée par une succession de pliages en omégas.The device according to the invention, which comprises a fluid supply pipe having a curved deformable part, is characterized in that this part is located approximately in a plane. This deformable part is advantageously formed by a succession of folds in omegas.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du dispositif d'alimentation selon l'invention, avec référence aux dessins annexés dans lesquels
La Figure 1 est une vue en plan
d'un essieu arrière comportant
ce dispositif d'alimentation;
La Figure 2 en est une coupe
transversale, à plus grande échelle,
suivant Il-Il de la Figure 1;
La Figure 3 en est une vue en
élévation, suivant la flèche F
de la Figure 2;
La Figure 4 montre la déformation
du tuyau d'alimentation lors de
l'oscillation du bras de support
de roue.An embodiment of the supply device according to the invention has been described below, by way of non-limiting example, with reference to the accompanying drawings in which
Figure 1 is a plan view
a rear axle comprising
this feeding device;
Figure 2 is a section
transverse, on a larger scale,
along Il-Il in Figure 1;
Figure 3 is a view in
elevation, following arrow F
of Figure 2;
Figure 4 shows the deformation
supply hose when
the oscillation of the support arm
wheel.

Au dessin, on voit un essieu arrière comprenant un tube 1 dont les extrémités sont emmanchées et fixées dans des traverses 2, elles-mêmes fixées sous ~ le plancher du véhicule. Sur chacune des extrémités du tube 1 est monté oscillant un bras support de roue 3. La référence 4 désigne deux barres de suspension agissant en torsion dont chacune a l'une de ses extrémités fixée à l'un des bras 3 alors que son autre extrémité est fixée à la traverse 2 située du côté opposé
Les freins gauche et droit sont alimentés par des tuyaux 5. Chacun de ces tuyaux comprend une première partie fixée en A au tube 1, une seconde partie fixée en B au bras 3, et entre ces deux parties, entre les points A et B, une partie déformable qui est située approximativement dans un plan au niveau du tube 1 et pliée en formant une succession d'omégas.In the drawing, we see a rear axle comprising a tube 1, the ends of which are fitted and fixed in cross members 2, themselves fixed under the vehicle floor. On each end of the tube 1 is mounted a oscillating wheel support arm 3. The reference 4 designates two suspension bars acting in torsion, each of which has one of its ends fixed to one of the arms 3 while its other end is fixed to the crossmember 2 located on the opposite side
The left and right brakes are supplied by pipes 5. Each of these pipes comprises a first part fixed at A to the tube 1, a second part fixed at B to the arm 3, and between these two parts, between points A and B, a deformable part which is situated approximately in a plane at the level of the tube 1 and bent by forming a succession of omegas.

Le point milieu C de la partie déformable du tuyau 5 est engagée dans un clip 6 prévu à l'extrémité d'une première pièce 7. Celle-ci est montée pivotante, autour d'un axe perpendiculaire à l'axe du tube 1 et au plan de la partie déformable du tuyau 5, par rapport à une seconde pièce 8 clippée sur le tube 1.The midpoint C of the deformable part of the pipe 5 is engaged in a clip 6 provided at the end of a first part 7. The latter is pivotally mounted, around an axis perpendicular to the axis of the tube 1 and in terms of the deformable part of the pipe 5, relative to a second part 8 clipped onto the tube 1.

La pièce 7 peut pivoter par rapport à la pièce 8 qui peut elle-même pivoter autour du tube 1. The part 7 can pivot relative to the part 8 which can itself pivot around the tube 1.

Lorsque l'un des bras 3 pivote, le point B vient par exemple en B' (Figure 4); la pièce 8 pivote sur le tube I d'un angle moitié et le point C vient en C'.When one of the arms 3 pivots, the point B comes for example at B '(Figure 4); the part 8 pivots on the tube I by a half angle and the point C comes at C '.

Les tuyaux 5 peuvent être montés sur l'essieu assemblé, avec fixation de leurs extrémités en
A et B et clippage de leurs parties déformables en C.The pipes 5 can be mounted on the assembled axle, with their ends fixed in
A and B and clipping of their deformable parts in C.

Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
