Abstract

The forecarriage includes: - a framework 10 articulated with respect to the chassis 9 of the trailer 5, by means of an orientation ring 11; - an axle 12, possibly a suspended axle, carried by the said framework 10; - a hitch 7 providing the link between the framework 10 and the hook 6 located to the rear of the lorry 1. The hitch 7 is located, in the normal position, in a substantially horizontal plane anchored to the framework 10 at the same level as the axis of the axle 12. The axle is arranged slightly set back from the vertical axis of gyration of the orientation ring 11; this set back lies between zero and fifteen centimetres, preferably five centimetres.

Description

La présente invention concerne un avant-train pour remorque de camion. The present invention relates to a front end for a truck trailer.

Les avant-trains modernes de remorque sont généralement articulés par rapport a l'avant du châssis au moyen d'une couronne d'orientation ; l'essieu est équipé d'un système de freinage ainsi que d'une suspension. Modern trailer fore-ends are generally articulated with respect to the front of the chassis by means of a slewing ring; the axle is equipped with a braking system as well as a suspension.

La liaison entre l'avant-train de la remorque et le camion s'effectue au moyen d'un attelage, lequel est, de façon classique, positionné a la partie supérieure de l'avant-train pour se fixer, au niveau du camion, sur un crochet disposé lui aussi relativement haut sur le châssis du camion. The connection between the front end of the trailer and the truck is effected by means of a hitch, which is conventionally positioned at the top of the front end to be fixed, at the level of the truck , on a hook also placed relatively high on the chassis of the truck.

De nouveaux systèmes d'attelage de longueur variable, pour réduire l'intervalle entre le camion et sa remorque comme décrit en particulier dans les documents FR-A-2.533.172, 2.570.654, 2.585.295, sont apparus ces nouveaux systèmes d'attelage représentent une masse importante suspendue pour partie, à l'avant-train de la remorque. Par ailleurs, ces systèmes d'attelage ont entrainé une augmentation assez nette de la longueur des remorques et en particulier de l'empattement, par rapport aux remorques classiques ; et il est apparu des mouvements au niveau de l'avant-train qui provoquent une certaine instabilité. New coupling systems of variable length, to reduce the interval between the truck and its trailer as described in particular in the documents FR-A-2,533,172, 2,570,654, 2,585,295, these new systems have appeared. 'hitch represents a large mass suspended partly, in the front end of the trailer. Furthermore, these coupling systems have resulted in a fairly marked increase in the length of the trailers and in particular in the wheelbase, compared with conventional trailers; and there were movements in the forefoot that caused some instability.

L'invention a pour objet un avant-train qui permet de pallier les inconvénients apparus ; elle a pour but d'améliorer la géométrie de l'avant-train et par la d'améliorer nettement la stabilité, en toutes circonstances, de la remorque. The subject of the invention is a front end which overcomes the drawbacks which have appeared; its purpose is to improve the geometry of the front end and thereby significantly improve the stability, in all circumstances, of the trailer.

L'avant-train selon l'invention, comporte : - un bâti articulé par rapport au châssis de la remorque au moyen d'une couronne d'orientation, - un essieu, éventuellement suspendu, porté par ledit bâti, - et un attelage assurant la liaison entre ledit bâti et un crochet situé à l'carrière du camion ; l'attelage est disposé sensiblement à l'horizontale derrière le camion et son ancrage sur le bâti de l'avanttrain s'effectue sensiblement au même niveau que l'axe de l'essieu dudit avant-train, dans la position normale moyenne de la remorque, lors du roulage.  The front end according to the invention comprises: - a frame articulated with respect to the chassis of the trailer by means of an orientation ring, - an axle, possibly suspended, carried by said frame, - and a coupling ensuring the connection between said frame and a hook located at the quarry of the truck; the coupling is arranged substantially horizontally behind the truck and its anchoring on the foreground frame is effected substantially at the same level as the axis of the axle of said fore-end, in the normal normal position of the trailer, when driving.

Toujours selon l'invention, l'axe de l'essieu est disposé en retrait de l'axe de giration de la couronne d'orientation. Ce retrait est compris entre O et 15 centimètres ; de préférence il est sensiblement égal à 5 centimètres. Still according to the invention, the axle axis is set back from the axis of gyration of the slewing ring. This shrinkage is between 0 and 15 centimeters; preferably it is substantially equal to 5 centimeters.

Toujours selon l'invention, le bâti comporte, à l'avant, des bras d'ancrage de l'attelage, qui s'étendent vers le bas, solidaires des structures de soutien du systeme de suspension de l'essieu. Still according to the invention, the frame comprises, at the front, hitch anchoring arms, which extend downward, integral with the support structures of the axle suspension system.

L'invention sera mieux comprise à l'aide de la description suivante et des dessins annexés donnés à titre indicatif, et dans lesquels - la figure 1 représente de façon schématique la partie arrière d'un camion et la partie avant d'une remorque l'attelage étant du type à longueur variable - la figure 2 représente, de façon schématique, le bati de l'avant-train de la remorque - la figure 3 représente une demi-vue de dessus du bâti représenté figure 2. The invention will be better understood with the aid of the following description and of the appended drawings given as an indication, and in which - FIG. 1 schematically represents the rear part of a truck and the front part of a trailer l the coupling being of the variable length type - FIG. 2 represents, schematically, the frame of the front end of the trailer - FIG. 3 represents a half-view from above of the frame shown in FIG. 2.

Tel que représenté figure 1, la partie arrière du camion 1 comporte, sous son chassis 2, une structure 3 qui s'étend vers le bas derrière les roues 4, et qui porte, tourné vers la remorque 5, un crochet 6 recevant un attelage 7 qui assure la liaison entre ledit camion 1 et ladite remorque 5. On a representé à titre d'exemple de réalisation, un attelage 7 du type décrit dans les documents
FR-A-2.570.654 et 2.585.295 précités. Ce type d'attelage permet de réduire considérablement l'espace mort entre la paroi arrière du camion et la face avant de la remorque. Des moyens particuliers, non décrits, et ne faisant pas partie de l'invention, commandent l'évolution automatique de la longueur de l'attelage 7.La remorque 5 comporte un avanttrain 8 disposé sous le châssis 9 et constitué : - d'un bati 10 articulé au moyen d'une couronne d'orientation 11 solidaire dudit bâti et du châssis 9 de la remorque ; - d'un essieu 12 solidaire du bati 10 par des moyens de suspension classiques, non représentés, articulés en particulier sur une structure verticale 13 qui apparait à l'avant de la roue 14, derriere le bras vertical 15 qui sert d'ancrage a l'attelage 7.
As shown in Figure 1, the rear part of the truck 1 has, under its chassis 2, a structure 3 which extends down behind the wheels 4, and which carries, turned towards the trailer 5, a hook 6 receiving a hitch 7 which provides the connection between said truck 1 and said trailer 5. A coupling 7 of the type described in the documents has been shown as an example of embodiment.
FR-A-2.570.654 and 2.585.295 cited above. This type of coupling considerably reduces the dead space between the rear wall of the truck and the front face of the trailer. Particular means, not described, and not forming part of the invention, control the automatic evolution of the length of the hitch 7.The trailer 5 comprises a pre-train 8 disposed under the chassis 9 and consisting of: frame 10 articulated by means of an orientation ring 11 secured to said frame and to the chassis 9 of the trailer; - An axle 12 secured to the frame 10 by conventional suspension means, not shown, articulated in particular on a vertical structure 13 which appears at the front of the wheel 14, behind the vertical arm 15 which serves to anchor a hitch 7.

Le bâti 10 est représenté de façon plus détaillé, figure 2 et figure 3. Ce bâti 10 est essentiellement constitué d'un cadre rectangulaire sur lequel est fixée la couronne d'orientation 11 elle-même solidaire de la remorque l'axe de giration vertical 16 de cette couronne d'orientation est représenté sur les deux figures. On remarque également, fig. 3, l'essieu 12 et en particulier sa position par rapport a l'axe 16 de la couronne d'orientation 11. The frame 10 is shown in more detail, Figure 2 and Figure 3. This frame 10 consists essentially of a rectangular frame on which is fixed the slewing ring 11 itself secured to the trailer the vertical axis of gyration 16 of this slewing ring is shown in the two figures. We also notice, fig. 3, the axle 12 and in particular its position relative to the axis 16 of the slewing ring 11.

;'axe 17 de l'essieu se situe sensiblement en retrait de l'axe 16, c'est-à-dire vers l-'arrière de la remorque, à une distance L qui se situe dans une fourchette de zéro à quinze centimètres environ. Pour ce type d'exemple de réalisation, les essais ont permis de fixer à L une valeur de l'ordre de cinq centimètres. the axis 17 of the axle is located substantially behind the axis 16, that is to say towards the rear of the trailer, at a distance L which is within a range of zero to fifteen centimeters about. For this type of exemplary embodiment, the tests made it possible to fix at L a value of the order of five centimeters.

Sur la partie avant du bâti 10, on trouve le bras 15 vertical destiné a l'ancrage de l'attelage 7 articulé sur un axe 18. Cet axe 18 se situe, comme montré figures 1 et 2, sensiblement au même niveau que, d'une part, l'axe 17 de l'essieu 12 de l'avant-train lorsqu'il est en position moyenne normale de roulage, et d'autre part, le crochet 6 disposé a la partie arriere du camion. Cette disposition permet en particulier, une meilleure transmission des efforts entre la remorque et le camion par l'intermédiaire de l'attelage 7 en position normale. On the front part of the frame 10, there is the vertical arm 15 intended for anchoring the coupling 7 articulated on an axis 18. This axis 18 is located, as shown in FIGS. 1 and 2, substantially at the same level as, d on the one hand, the axis 17 of the axle 12 of the front end when it is in the normal normal rolling position, and on the other hand, the hook 6 disposed at the rear of the truck. This arrangement allows in particular a better transmission of forces between the trailer and the truck by means of the coupling 7 in the normal position.

Tel que représenté figure 3, l'attelage 7 a une forme sensiblement triangulaire et se fixe en fait sur les bras verticaux 15 disposés sensiblement au coin avant du bâti 10. Ces bras 15 sont adossés aux structures verticales 13 qui servent d'ancrage et notamment d'articulation au systeme de suspension, non représenté, de l'essieu 12. As shown in FIG. 3, the coupling 7 has a substantially triangular shape and is in fact fixed on the vertical arms 15 disposed substantially at the front corner of the frame 10. These arms 15 are backed by the vertical structures 13 which serve as anchors and in particular articulation to the suspension system, not shown, of the axle 12.

On voit également figure 3, le décalage L entre l'axe de giration 16 de la couronne d'orientation 11 et l'axe 17 de l'essieu 12. Cet axe de giration se situe sensiblement en avant de l'axe 17 de l'essieu.  Also seen in Figure 3, the offset L between the axis of gyration 16 of the slewing ring 11 and the axis 17 of the axle 12. This axis of gyration is located substantially in front of the axis 17 of the 'axle.
