Abstract

The frame for towing motor-cles comprises a chassis (1) carrying a ball-joint (2) which attaches to a towing bracket (3). Two blocks (5) are welded to the chassis (1) and receive anchorage points (4) for removable straps which are held in a retracted or deployed position by split-pins (12). An adjustable frame (6) receives the rear wheel of the bike and is bolted to the chassis. Another frame (9) is attached to the end of the chassis and carries adjustable bolts (10) which locate into the ends of the front wheel axle and hold the wheel steady as it rotates in transit.

I1 existe actuellement différentes solutions pour transporter des motocyclettes avec un véhicule automobile s - charger la moto dans le véhicule ; encore faut-il que le véhicule soit
suffisamment grand - oharger la moto dans une remorque et la tracter ; en dehors de ltuti-
lisation un problème de parking se pose - charger la moto eur une remorque spéciale monoroue et la tracter ;
ici encore il y a un problème de parking et d'encombrement - charger la moto sur un système qui s'accroche à l'arrière de l'auto
mobile, la moto étant portée et en travers du véhicule ; d'où grande
largeur de l'ensemble roulant dans bien des cas et poids limité de la
moto - utiliser "un moto tract" derrière l'automobile; la roue avant de la
moto étant portée par le moto tract, la roue arrière roule sur le sol ;
il y a nécessité de déorocher la chaîne, usure supplémentaire du pneu
arrière, qui se détériore rapidement sur une moto, difficulté de
manoeurer en marche arrière, la moto se couchant dès que l'attelage
auto-moto n'est plus aligné
L'invention évite inconvénients exposés ci-desnus ; en effet, on met en action un système simple, léger, peu encombrant qui . réduit la dimension du véhicule tracteur ou porteur . élimine les problèmes de garage d'une remorque . n'oblige pas à décrocher la chaîne de la moto . autorise toutes les manoeuvres de l'attelage sans difficultés parti
culières . permet le transport d'un poids allant jusqu'à 250 kg.There are currently different solutions for transporting motorcycles with a motor vehicle; loading the motorcycle into the vehicle; still the vehicle must be
large enough - load the motorcycle in a trailer and tow it; outside the uti-
There is a parking problem - load the motorbike with a special single-wheel trailer and tow it;
here again there is a problem of parking and space - load the motorcycle on a system which hangs on the back of the car
mobile, the motorcycle being carried and across the vehicle; where great
width of the rolling assembly in many cases and limited weight of the
motorbike - use a "motorbike" behind the automobile; the front wheel of the
motorbike being carried by the motorbike tractor, the rear wheel rolls on the ground;
there is a need to loosen the chain, additional tire wear
rear, which deteriorates quickly on a motorcycle, difficulty
maneuver in reverse, the motorcycle setting down as soon as the coupling
auto-moto is no longer aligned
The invention avoids the drawbacks set out above; indeed, we put into action a simple, light, space-saving system which. reduces the size of the tractor or carrier vehicle. eliminates garage problems from a trailer. does not require you to unhook the chain from the motorcycle. authorizes all maneuvers of the coupling without leaving difficulties
culières. allows the transport of a weight of up to 250 kg.

Le dispositif est réalisé en tubes de section carrée profilés à froid et assemblEs par soudure électrique. The device is made of cold-shaped square section tubes and assembled by electric welding.

Il se compose d'un cadre 1, d'un Joint de cardan 2, assemblé par boulons ou soudé au cadre 1, dune plaque 3 qui sert à assembler le porte- moto au véhicule tracteur, de deux encastrements 5 soudés au cadre 1, recevant deux ancrages de sangle 4 amovibles et tenus en position utili- sation (extension) ou en position rétractée (cas du rangement du porte moto) par deux goupilles bêta 12. Un chariot en tubes soudés 6 se place sur le cadre 1, la roue arrière de la moto a'encastre dedans. Sa position est réglable, il est bloqué par quatre boulone 7 et rondelles 13 qui le pincent sur le cadre 1 (voir coupe AA). It consists of a frame 1, a Cardan joint 2, assembled by bolts or welded to the frame 1, a plate 3 which is used to assemble the motorcycle carrier to the towing vehicle, two recesses 5 welded to the frame 1, receiving two removable strap anchors 4 held in the use position (extension) or in the retracted position (in the case of storing the motorcycle carrier) by two beta pins 12. A trolley made of welded tubes 6 is placed on the frame 1, the wheel rear of the motorcycle to be fitted into it. Its position is adjustable, it is blocked by four bolts 7 and washers 13 which pinch it on the frame 1 (see section AA).

Une deuxième partie 8 amovible en tubes carrés soudés, de zection inférieure aux tubes de la pièce 1, s'assemble à celle-ci par amboîtement et est maintenne en position par deux vis 9.
