Abstract

Device making it possible to adapt a trailer whose hitching gear is longitudinally rigid and articulated horizontally to light 3, 4, or 5 door cars or vehicles with a short rear overhang. It comprises a draw bar 1 with a hitching gear casing 2 for a standard ball, a removable front support 3 fixed to the roof of the vehicle and equipped with two slides 4 which guide two shafts 5 which are securely fixed to the trailer. The hitching gear is materialised by an isosceles triangle ASB in which the point S is articulated on the ball. The apexes A and B are mounted slidably on the roof within the wheelbase of the vehicle. The device is intended for utility trailers or leisure trailers of low total weight when loaded. It makes it possible to use the volume on the axle of the trailer as well as the volume situated beneath the vehicle within the permitted load limits of the latter.

Description

Une très large part des attelages classiques voitures, ou véhicules légers, avec remorques légères se présentent sous l'aspect de la fig.1 et sont constitués d'un attelage à boule suivi d'un timon d'une longueur égale à la demi-longueur de la voiture plus une garde de 0,20 mètre, soit environ 1 mètre. A very large part of the classic car couplings, or light vehicles, with light trailers are presented in the aspect of fig. 1 and consist of a ball coupling followed by a drawbar with a length equal to half length of the car plus a guard of 0.20 meters, about 1 meter.

Dans cette configuration un espace D (fig.1) doit être réservé entre l'arrière de la voiture et l'avant de la remorque pour le balayage du volume en virage. L'ensemble constitue un attelage articulé démesurément long. In this configuration, a space D (fig. 1) must be reserved between the rear of the car and the front of the trailer for sweeping the volume when cornering. The whole constitutes a disproportionately long articulated hitch.

L'espace D est relativement important et lorsque la voiture freine et braque intempestivement avec une remorque en charge non freinée, il en résulte un risque de mise en portefeuille" de l'ensemble attelé. The space D is relatively large and when the car brakes and turns unexpectedly with a trailer under unbraked load, this results in a risk of portfolio "of the coupled assembly.

Le but de l'invention est de conserver le eap à ltensemble du convoi en utilisant l'adhérence totalisée des six pneumatiques, quelque soit la trajectoire du véhicule tracteur, tout en réduisant à zéro l'espace D (figes 2). D'autre part, le report des charges dynamiques de la remorque du nu freinage du véhicule tracteur sera appliqué sensiblement à mi- longueur de 1 'empattement, ce qui tend à stabiliser la voiture et à répare tir également le freinage sur les quatres roues du véhicule tracteur. The object of the invention is to keep the eap to the whole convoy by using the totalized grip of the six tires, whatever the trajectory of the towing vehicle, while reducing the space D to zero (figs 2). On the other hand, the deferral of the dynamic loads of the trailer from the bare braking of the towing vehicle will be applied substantially at mid-length of the wheelbase, which tends to stabilize the car and also repair the braking on the four wheels of the towing vehicle.

La fgare 1 représente l'épure d'un attelage classique. Fig. 1 represents the simplicity of a classic team.

La figure 2 représente l'épure de l'attelage objet de l'invention. Figure 2 shows the drawing of the coupling object of the invention.

La figure 3 représente la vue en élévation de l'ensemble attelé. FIG. 3 represents the elevation view of the coupled assembly.

La figure 4 représente la vue en plan de l'ensemble attelé. FIG. 4 represents the plan view of the coupled assembly.

La figure 5 représente la fixation du boitier d'attelage à boule normalisée, adapté à l'invention. Figure 5 shows the attachment of the standard ball coupling box, adapted to the invention.

La figure 6 représente l'une des deux coulisses avants. Figure 6 shows one of the two front slides.

Selon la présente invention, le dispositif d'attelage permet de supprimer l'espace D entre voiture et remorque et seadapte sur toutes les voitures ou véhicules légers : trois, quatre, cinq portes à faible porte à faux arrière. According to the present invention, the coupling device eliminates the space D between car and trailer and fits on all cars or light vehicles: three, four, five doors with low rear overhang.

Il comprend un timon (1) avec un boitier d'attelage rapide (2) à boule fixé souplement sur le timon (1) par l'interposition d'un amortisseur (6) (fig.5) qui contrôle la variation de l'angle o( (fig.3). Un support avant (3) amovible et fixé sur le toit du véhicule tracteur. Un plus un coulisseaux (4) fixés souplement sur le support (3) par interposition d'éléments anti-vibratoires (7) (fig.6). Un plus un brancards (5) montés glissant dans les coulisseaux (4) et solidaires de la remorque.  It includes a drawbar (1) with a quick coupling box (2) with ball loosely attached to the drawbar (1) by the interposition of a shock absorber (6) (fig.5) which controls the variation of the angle o ((fig.3). A removable front support (3) fixed on the roof of the towing vehicle. One more one slides (4) fixed flexibly on the support (3) by interposition of anti-vibration elements (7 One (1) stretchers (5) mounted sliding in the slides (4) and integral with the trailer.

La géométrie de l'attelage est matérialisée par un triangle isocèle
ASB contenu dans le plon P de la fig. 3. Ce triangle isocèle représente les trois points de fixation de l'attelage. Le sommet S est confondu avec l'axe de la rotule, à l'arrière du véhicule tracteur, et assure la traction de la remorque. Les deux autres sommets A et B de la base du triangle sont montés en coulisse sur le toit de la voiture suivant la fig. 6, à l'intérieur de l'empattement. Les glissières des coulisseaux sont usinées en forme convexe afin de permettre à ceux-ci différentes orientations dans le plan vertical. r
L'attelage tel que décrit, transforme l'ensemble voiture-remorque en un volume rigide dans le plan horizontal, tout en conservant l'indépendance des volumes voiture et remorque dans le plan vertical. L'ensemble attelé réagit en tenue de route comme un véhicule 6X2 à roues indépendantes et peut se désolidariser comme un attelage voiture-remorque classique avec en plus la sécurité qu'offrent en cas de rupture de la boule ou de son support, les deux points A et B de fixation avant sur le toit de la voiture.The hitch geometry is materialized by an isosceles triangle
ASB contained in plon P of fig. 3. This isosceles triangle represents the three attachment points of the hitch. The apex S coincides with the axis of the ball joint, at the rear of the towing vehicle, and provides traction for the trailer. The other two vertices A and B of the base of the triangle are mounted behind the scenes on the roof of the car according to fig. 6, inside the wheelbase. The slides of the slides are machined in a convex shape in order to allow them different orientations in the vertical plane. r
The coupling as described transforms the car-trailer assembly into a rigid volume in the horizontal plane, while preserving the independence of the car and trailer volumes in the vertical plane. The hitched assembly reacts in road holding like a 6X2 vehicle with independent wheels and can be disassociated like a classic car-trailer hitch with in addition the security offered in the event of a break in the ball or its support, the two points A and B of front fixing on the roof of the car.

La description de cette invention n'est pas limitotive. Toutes autres réalisations employant des principes similaires sous d'autres formes, celles-ci pouvant varier à l'infini, tombent dans le domaine de la protection.  The description of this invention is not limiting. All other embodiments employing similar principles in other forms, which may vary endlessly, fall within the field of protection.
