Abstract

The rigid band (1) surrounds the towing vehicle (2), but is not rigidly attached to it. The band is rigidly attached to the towed vehicle (3), allowing easy towing and reversing of the vehicle train.

Description

La présente invention concerne un dispositif pour assembler deux véhicules. The present invention relates to a device for assembling two vehicles.

Lorsque deux véhicules sont assemblés, généralement un tracteur et une remorque, ils sont liés par une attache ponctuelle autorisant une relative indépendance de leurs mouvements notamment en virage serré. When two vehicles are assembled, generally a tractor and a trailer, they are linked by a point attachment allowing relative independence of their movements, especially in tight turns.

Ce principe a au moins deux inconvénients. This principle has at least two drawbacks.

II nécessite un espace suffisant entre les deux véhicules pour que quelque soient leurs positions respectives lors d'une manoeuvre, leurs formes avant et arrière ne s'entrechoquent pas. D'où il résulte une perte de volume utile pour l'un et l'autre des véhicule au regard de l'encombrement en longueur qu'ont les deux véhicules une fois réunis. D'autre part, la manoeuvrabilité d'un tel système est problématique, notamment en marche arrière, dans la mesure où tous les mouvements du tracteur ne peuvent être transmis à ceux du véhicule remorqué puisque leur liaison n'est pas rigide. It requires sufficient space between the two vehicles for whatever their respective positions during a maneuver, their front and rear shapes do not collide. This results in a loss of useful volume for one and the other of the vehicle with regard to the overall length that the two vehicles have once combined. On the other hand, the maneuverability of such a system is problematic, in particular in reverse, insofar as all the movements of the tractor cannot be transmitted to those of the towed vehicle since their connection is not rigid.

Le dispositif selon l'invention remédie à ces inconvénients. II comporte en effet selon une première caractéristique une ceinture rigide entourant le tracteur mais non fixée à celui-ci, et solidaire du véhicule remorqué. Le tracteur en mouvement entraîne la ceinture et donc la remorque dans toutes les directions où il se dirige. Les faces arrière du tracteur et les faces avant de la remorque peuvent être aussi à proximité sans inconvénient. Dans le cas d'une manoeuvre de recul, les mouvements imprimés par le tracteur sont directement transmis au véhicule remorqué. The device according to the invention overcomes these drawbacks. According to a first characteristic, it in fact comprises a rigid belt surrounding the tractor but not fixed to it, and secured to the towed vehicle. The moving tractor drives the belt and therefore the trailer in all directions where it is going. The rear sides of the tractor and the front sides of the trailer can also be nearby without inconvenience. In the case of a reversing maneuver, the movements printed by the tractor are directly transmitted to the towed vehicle.

Selon un mode particulier de réalisation, l'intérieur de la ceinture a une forme de cercle et le tracteur de forme circulaire s'inscrit à l'intérieur de ce cercle. According to a particular embodiment, the inside of the belt has the shape of a circle and the tractor of circular shape fits inside this circle.

Le tracteur peut alors tourner autour de son axe vertical selon les commandes de son conducteur. Selon la direction choisie, il imprime alors un mouvement à l'ensemble des deux véhicules.The tractor can then turn around its vertical axis according to the commands of its driver. Depending on the direction chosen, it then prints a movement on all of the two vehicles.

Les dessins annexés illustrent l'invention:
La Figure 1 représente selon une coupe horizontale le dispositif de l'invention.
The accompanying drawings illustrate the invention:
Figure 1 shows in a horizontal section the device of the invention.

La Figure 2 représente selon une coupe horizontale une variante de ce dispositif. Figure 2 shows in a horizontal section a variant of this device.

En référence à ces dessins, la ceinture rigide (1) entoure le tracteur (2) sans être fixée à celui-ci et est fixée solidairement à la remorque (3).  With reference to these drawings, the rigid belt (1) surrounds the tractor (2) without being fixed to it and is fixedly attached to the trailer (3).

Dans la forme de réalisation selon la Figure 2, la ceinture rigide (1) dont l'intérieur a une forme de cercle, entoure le tracteur (2) de forme circulaire. La ceinture est fixée solidairement à la remorque (3). Le tracteur peut tourner autour de son axe vertical (4). In the embodiment according to Figure 2, the rigid belt (1) whose interior has a circle shape, surrounds the tractor (2) of circular shape. The belt is fixed securely to the trailer (3). The tractor can turn around its vertical axis (4).

A titre d'exemple non limitatif, la ceinture est métallique et soudée à la remorque. La section en vertical du tracteur a un double épaulement de telle façon que les efforts verticaux de la ceinture dus au transfert du poids de la remorque au tracteur soient repris. Ces épaulements sont écartés en hauteur d'une distance suffisante, par exemple 20 cm, pour permettre à la ceinture d'avoir une fonction de palier en étant muni de paliers radiaux et axiaux, et donc de limiter les éventuelles différences de dévers longitudinaux et latéraux du tracteur et de la remorque provenant de mouvements de leurs suspensions respectives. By way of nonlimiting example, the belt is metallic and welded to the trailer. The vertical section of the tractor has a double shoulder so that the vertical efforts of the belt due to the transfer of the weight from the trailer to the tractor are taken up. These shoulders are spaced apart by a sufficient distance, for example 20 cm, to allow the belt to have a bearing function by being provided with radial and axial bearings, and therefore to limit any differences in longitudinal and lateral superelevation tractor and trailer from movements of their respective suspensions.

Dans ce cas, le tracteur peut être équilibré dans une position verticale grâce aux réactions foumies par la surface d'appui des épaulements en son pourtour, et ses roues qui peuvent être seulement deux et fixées à un seul essieu transversal dont le centre est fixé au niveau de l'axe central du tracteur. Dans ce cas, I'essieu du tracteur peut être rotatif autour de l'axe vertical du tracteur et commandé par la direction du tracteur.In this case, the tractor can be balanced in a vertical position thanks to the reactions provided by the bearing surface of the shoulders around its periphery, and its wheels which can be only two and fixed to a single transverse axle whose center is fixed to the level of the tractor center line. In this case, the tractor axle can be rotatable about the vertical axis of the tractor and controlled by the direction of the tractor.

La ceinture peut être ouvrable selon notamment un système où la demimoitié avant vient s'emboîter dans la demi-moitié arrière, de façon à séparer si besoin le tracteur de la remorque. The belt can be opened in particular according to a system where the front half is fitted into the rear half-half, so as to separate the tractor from the trailer if necessary.

Ce dispositif est destiné aux véhicules.  This device is intended for vehicles.
