Description

La présente invention concerne un dispositif de graissaEe des sellettes et des plaques d'attelage de tracteurs et de semi-remor quels.  The present invention relates to a device for greasing harnesses and coupling plates of tractors and semi-trailers.

Aotuellement, sur les tracteurs et les semi-remporques, a sel- lette et la plaque d'attelage sont graissés à la spatule ou à la truelle avant l'attelage de la semi-remorque. Lors de l'attelage, la graisse flue de chaque c8te de la sellette et il en résulte une perte de graisses une mauvaise répartition de la graisse restante et, par conséquent, une lubrification irreguliere et assez éphémère. At times, on tractors and semi-trailers, the selector wheel and the coupling plate are greased with a spatula or trowel before coupling the semi-trailer. During coupling, the fat flows from each side of the harness and this results in loss of fat, poor distribution of the remaining fat and, consequently, irregular and fairly ephemeral lubrication.

Ce défaut de graissage, qui contrarie la libre rotation de la plaque par rapport à la sellette, se traduit indirectement par une usure prématurée des deux pivots de direction, ainsi que des pneus et des bagues des ressorts avant du tracteur et de la sellette. This lack of lubrication, which impedes the free rotation of the plate relative to the fifth wheel, results indirectly in premature wear of the two steering pivots, as well as the tires and rings of the front springs of the tractor and the fifth wheel.

Le dispositif selon l'invention, vise à remédier à ces incon venients, car avec celui-ci, en effet, le graissage s'effectue sous pression, en plusieurs points de la sellette et de la plaque, individuellement ou collectivement, la semi-remorque étant attelée, à partir d'une centrale de graissage porte par le tracteur. The device according to the invention aims to remedy these drawbacks, because with it, in fact, lubrication is carried out under pressure, at several points of the harness and of the plate, individually or collectively, the semi- trailer connected, from a central lubrication unit carried by the tractor.

Ce dispositif se caracterise principalement en ce qu'il comporte plusieurs orifices de graissage raccordés par des tuyauteries souples annees, à une centrale de graissage sous pression. This device is mainly characterized in that it comprises several lubrication orifices connected by flexible year pipes, to a pressurized lubrication unit.

Sur la sellette, les orifices de graissage débouchent dans la cannelure de graissage, dans la partie lisse située entre la cannelure et la zône de pivotement et dans la z8ne de pivotement. Dans la cannelure, les orifices de graissage sont situés aux extrêmités et au milieu de celle-ci. Sur la plaque d'attelage, les orifices de graissage débouchent dans la surface de contact avec la sellette. On the fifth wheel, the lubrication holes open into the lubrication groove, in the smooth part located between the groove and the pivot zone and in the pivot zone. In the groove, the lubrication holes are located at the ends and in the middle of it. On the coupling plate, the lubrication holes open into the contact surface with the fifth wheel.

D'autres caractéristiques et avantages apparaitront dans la description qui va suivre d'un dispositif de graissage d'une sellette et d'une plaque d'attelage de semi-remorque donné à titre d'exemple non limitatif au regard des dessins annexés sur lesquels t

- Figure 3 shows the detail of connection of the pipes to the fifth wheel or to the coupling plate and to the control unit
lubrication.

L'attelage s'effectue par l'intermédiaire de la sellette I, de la plaque 2 et de l'axe de pivotement 3. The coupling is carried out by means of the fifth wheel I, the plate 2 and the pivot axis 3.

La sellette I possède une cannelure de graissage Ia, dans laquelle débouchent les orifices de graissage 4, 5 et 6, une partie lisse Ib comportant les orifices de graissage 7 et 8 et une ebne de pivotement Ic munie d'un orifice de graissage 9. The harness I has a lubrication groove Ia, into which the lubrication orifices 4, 5 and 6 open, a smooth part Ib comprising the lubrication orifices 7 and 8 and a pivoting ebony Ic provided with a lubrication orifice 9.

La plaque d'attelage 2 est munie de deux orifices de graissage 10 et II. The coupling plate 2 is provided with two lubrication orifices 10 and II.

Les orifices de graissage de la sellette sont raccordés directement à la centrale de graissage I2 par les tuyauteries I4, 15, 16, 17, I8 et 19. Les orifices de graissage de la plaque sont raccordés à la centrale de graissage 12 par les tuyauteries 20 et 21 et la tuyauterie escamotable 22. Les tuyauteries sont raccordées aux orifices de graissage par des raccords obliques 13.  The lubrication holes in the fifth wheel are connected directly to the lubrication center I2 by the pipes I4, 15, 16, 17, I8 and 19. The lubrication holes in the plate are connected to the lubrication center 12 by the pipes 20 and 21 and the retractable piping 22. The piping is connected to the lubrication orifices by oblique connections 13.

Sur la figure I, on remarque que les orifices de graissage 4 à 9 de la sellette sont réunis individuellement à la centrale de graissage 12 par les tuyauteries souples armées I4 à I9, alors que les orifices de graissage 10 et Il de la plaque sont raccordés à la centrale I2 par l'intermédiaire des tuyauteries souples 20 et 21 et la tuyauterie esoamotable 22t de façon à permettre une déconnection aisée lors du dételage de-la remorque.L'axe de pivotement est graissé par l'orifice 9 situé dans la zône de pivotement 10 de la sellette
Sur la figure 2, on remarque que les orifices de graissage 4, .5 et 6 débouchent aux extrêmités et au milieu de la cannelure de graissage la, que les orifices de graissage 7 et 8 débouchent dans la partie lisse b et que l'orifice 9 débouche dans la zône de pivotement le.
In FIG. 1, it can be seen that the lubrication orifices 4 to 9 of the fifth wheel are joined individually to the lubrication center 12 by the reinforced flexible pipes I4 to I9, while the lubrication orifices 10 and II of the plate are connected to the central unit I2 by means of flexible pipes 20 and 21 and the removable pipe 22t so as to allow easy disconnection during uncoupling of the trailer. The pivot axis is greased by the orifice 9 located in the area pivot 10 of the fifth wheel
In FIG. 2, it can be seen that the lubrication orifices 4, .5 and 6 open at the ends and in the middle of the lubrication groove la, that the lubrication orifices 7 and 8 open in the smooth part b and that the orifice 9 opens into the pivot zone.

Sur la figure 3, on remarque que le raccordement des tuyaute- ries aux orifices s'effectue par l'intermédiaire de raccords oblique 13, vissé à l'entrée des orifices,
Comme on le voit, ce dispositif permet un graissage complet du système d'attelage après que celui-ci est réalisé. Il suffit pour cela, de mettre les tuyauteries sous pression de graisse ou d'huile jusqu'à ce que celle-ci flue sur les cotes
Le conducteur de l'engin peut effectuer des graissages en cours de route lorsqu'il le juge utile puisque la centrale de graissage est constituée d'une pompe, aspirant dans un réservoir d'huile ou de graisse, mue par l'énergie électrique ou pneumatique générée par le tracteur.
In FIG. 3, it can be seen that the connection of the pipes to the orifices takes place by means of oblique connectors 13, screwed at the inlet of the orifices,
As can be seen, this device allows complete lubrication of the coupling system after it has been completed. For this, it is enough to put the pipes under pressure of grease or oil until it flows on the dimensions
The operator of the machine can carry out lubrication during the journey when he deems it useful since the lubrication center consists of a pump, sucking in a reservoir of oil or grease, driven by electrical energy or tire generated by the tractor.

Des dispositift simplifiés ne comportant pas de centrale de graissage peuvent néanmoins être envisagés lorsque le parcours s' effectue sur des routes comportant des stations services suffisam- ment rapprochées ou lorsque les déplacements s'effectuent dans un secteur assez limité. Simplified arrangements which do not include a lubrication center can nevertheless be envisaged when the journey is carried out on roads comprising sufficiently close service stations or when journeys are made in a fairly limited sector.

Le dispositif selon l'invention est destiné particulièrement aty ensembles trncteur et semi-remorque effectuant un important kilomètrage dans des régions ou des pays mal équipés en stations de graissage,  The device according to the invention is intended in particular for tractor and semi-trailer assemblies carrying out significant mileage in regions or countries poorly equipped with lubrication stations,
