Description

La présente invention concerne un tricycle utilitaire à moteur ayant une roue directrice à l'avant et deux roues à l'arrière dont au moins l'une est motrice. Le tricycle objet de la présente invention est un tricycle relativement petit, il a une seule place à l'avant pour le conducteur et possède un espace marchandises ou passagers situé entre et au dessus des deux roues arrières.The present invention relates to a utility motor tricycle having a steering wheel at the front and two wheels at the rear, at least one of which is driving. The tricycle object of the present invention is a relatively small tricycle, it has a single place in the front for the driver and has a goods or passenger space located between and above the two rear wheels.

Le poids à vide de ce tricycle ne représente qu'une fraction du poids des marchandises ou des passagers qu'il est capable de transporter. La vitesse maxi de ce tricycle est limitée, d'une part pour assurer une bonne sécurité active tout eli profitant de la grande maniabilité d'un tricycle avec roue avant directrice et d'autre part pour limiter la puissance installée donc le poids et le cout des parties motrices.The unladen weight of this tricycle represents only a fraction of the weight of the goods or passengers it is capable of transporting. The maximum speed of this tricycle is limited, on the one hand to ensure good active safety while taking advantage of the great maneuverability of a tricycle with steerable front wheel and on the other hand to limit the installed power therefore the weight and cost. of the driving parts.

Vue le rapport important, poids total en charge sur poids à vide, les suspensions et en particulier celles des deux roues arrières sont pratiquement inéfficaces lorsque le véhicule circule avec le conducteur et très peu de charge sur les roues arrières, ces conditions de fonctionnement ne sont pas négligeables pour un véhicule utilitaire dont une partie du taux d'utilisation est obligée d'être faite à vide pour se rendre sur les lieux de chargement ou revenir des lieux de déchargement. Un tricycle utilitaire étant l'instrument de travail du conducteur, son siège doit être très bien suspendu afin de lui assurer un confort acceptable, même pendant les trajets à vide.In view of the large ratio, total weight loaded over empty weight, the suspensions and in particular those of the two rear wheels are practically ineffective when the vehicle is traveling with the driver and very little load on the rear wheels, these operating conditions are not not negligible for a commercial vehicle for which part of the utilization rate is obliged to be made empty to go to the places of loading or return from the places of unloading. A utility tricycle being the driver's working instrument, his seat must be very well suspended in order to provide him with acceptable comfort, even during empty journeys.

Un tricycle utilitaire à moteur roule beaucoup et en conséquence son réservoir de carburant doit avoir une capacité importante pour éviter des passages trop fréquents à la station service.A utility motor tricycle rides a lot and therefore its fuel tank must have a large capacity to avoid too frequent trips to the service station.

Un tricycle utilitaire à moteur est très maniable, en conséquence il est fait pour se faufiler aussi bien dans les petites ruelles que dans les embouteillages des grandes artères de la circulation urbaine; en se faufilant il n'est pas impossible que , de temps en temps, il soit heurté ou heurte des obstacles, ceci en roulant à relativement basse vitesse, pour la protection du conducteur, des passagers ou des marchandises transportées, il est bon que le véhicule soit entouré par un pare choc éfficace.A utility motorized tricycle is very manoeuvrable, therefore it is made to squeeze in both small alleys and in traffic jams of major arteries of urban traffic; in sneaking it is not impossible that, from time to time, it is struck or collided with obstacles, this while driving at relatively low speed, for the protection of the driver, passengers or goods transported, it is good that the vehicle is surrounded by an effective bumper.

Le tricycle objet de la présente invention répond aux trois critères précités, à savoir: 1) suspension souple pour le siège du conducteur.The tricycle object of the present invention meets the three aforementioned criteria, namely: 1) flexible suspension for the driver's seat.

2) grande capacité pour le réservoir de carburant.2) large capacity for the fuel tank.

3) conducteur, passagers et marchandises protégés par un
pare choc éfficace.
3) driver, passengers and goods protected by a
effective bumper.

A cet éffet le chassis du tricycle utilitaire à moteur selon 1' invention est composé d'une poutre tubulaire en forme de U dont les deux jambages sont les cotés du tricycle et la base est l'avant du tricycle; le tube qui reçoit la colonne de direction de la roue avant est solidaire de la partie médiane de la base du U et le tube qui sert de support aux bras de suspension et au ou aux moteurs est relié à chacun des deux jambages du chassis en U.To this effect the chassis of the utility motor tricycle according to the invention is composed of a U-shaped tubular beam whose two legs are the sides of the tricycle and the base is the front of the tricycle; the tube which receives the steering column of the front wheel is integral with the middle part of the base of the U and the tube which serves to support the suspension arms and the motor (s) is connected to each of the two legs of the U-shaped chassis .

Le chassis en U est un corps creux avec une paroi suffisement épasse et non cassante pour servir à la fois de réservoir de carburait et de pare choc. Les deux jambages du U ne sont pas parallele au sol afin d'assurer un écoulement correct du carburant vers le ou les moteurs qui sont de préférence incorporés à l'un ou à chacun des bras de suspension des roues arrières.Un jeu de lame de ressort, parallèle à la base du U, s'articule sur des supports solidaires de chacun des jambages du chassis en U, ces lames de ressort servant de support au siège du conducteur; ceci permet d'une façon simple et peu encombrante, d'obtenir une excellente suspension pour le siège du conducteur; la partie basse située sous le siège est alors complètement libre pour permettre au conducteur de mettre les pieds au sol pour éffectuer, par propulsion pédestre, des petites manoeuvres, comme une marche arrière par éxemple. The U-shaped chassis is a hollow body with a sufficiently thick and non-brittle wall to serve as both a fuel tank and a bumper. The two legs of the U are not parallel to the ground in order to ensure correct flow of fuel to the engine or engines which are preferably incorporated into one or each of the suspension arms of the rear wheels. spring, parallel to the base of the U, is articulated on supports integral with each of the legs of the U-shaped chassis, these leaf springs serving to support the driver's seat; this allows in a simple and space-saving way, to obtain an excellent suspension for the driver's seat; the lower part located under the seat is then completely free to allow the driver to put his feet on the ground to carry out, by pedestrian propulsion, small maneuvers, such as reverse gear for example.

Les figures ci annexées représentent à titre indicatif et non limitatif un tricycle utilitaire à moteur selon l'invention.The attached figures show by way of non-limiting example a utility motor tricycle according to the invention.

La Fig. 1 est une vue en prespective du chassis, ceci pour un tricycle avec une seule roue arrière motrice.Fig. 1 is a perspective view of the chassis, this for a tricycle with a single rear wheel drive.

La Fig.2 est une vue latérale du tricycle coté moteur, le protège jambes étant retiré.Fig.2 is a side view of the tricycle on the engine side, the leg protector being removed.

La Fig. 3 est une vue latérale du tricycle coté opposé au moteur.Fig. 3 is a side view of the side tricycle opposite the engine.

La Fig. 4 est une coupe parallele au sol montrant les bras de suspension des roues arrières.Fig. 4 is a section parallel to the ground showing the suspension arms of the rear wheels.

Le chassis en U est parfaitement visible sur la Fig. 1, 2 est la base du U, 3 est l'un des jambages du U et 4 est l'autre jambage du U. 5 est le support sur lequel les lames de ressorts 6 et 7 qui reçoivent le siège 8 sont vissées, 9 est le support dans lequel les lames de ressorts 6 et 7 peuvent coulisser; si les supports 5 et 9 sont en caoutchouc, les lames 6 et 7 sont vissées sur les deux supports, le coulissement est alors remplacé par une déformation élastique des supports en caoutchouc. 10 est le tube qui reçoit la colonne de direction, 1 1 est le tube entretoise qui reçoit les bras de suspension 12, 13 des roues arrières 14,15; le moteur avec sa transmission 16 fait partie intégrante du bras de suspension 12; 17, 18, 19 et 20 sont les articulations des bras de suspension; 21,22 et 23 sont les attaches de ces articulations sur le tube 11.The U-shaped chassis is perfectly visible in Fig. 1, 2 is the base of the U, 3 is one of the legs of the U and 4 is the other leg of the U. 5 is the support on which the leaf springs 6 and 7 which receive the seat 8 are screwed, 9 is the support in which the leaf springs 6 and 7 can slide; if the supports 5 and 9 are made of rubber, the blades 6 and 7 are screwed onto the two supports, the sliding is then replaced by an elastic deformation of the rubber supports. 10 is the tube which receives the steering column, 1 1 is the spacer tube which receives the suspension arms 12, 13 of the rear wheels 14,15; the engine with its transmission 16 is an integral part of the suspension arm 12; 17, 18, 19 and 20 are the joints of the suspension arms; 21, 22 and 23 are the attachments of these articulations on the tube 11.

24 est le tube qui, avec le tube 1 1 sert à la fixation du plancher qui reçoit les passagers ou les marchandises à transporter. 25 est un arceau de sécurité qui sert également à la fixation d'une protection supérieure contre le soleil ou la pluie. Le bouchon 27 sert au remplissage en carburant du tube 4, 2, 3. Pour une bonne alimentation du moteur en carburant, le jambage 4 est nettement plus haut que, le jambage 3, ce dernier ayant à son extrémité la prise de reniflard 28, ce reniflard pouvant être un tube souple solidaire de la prise 28, ce tube souple montant à l'intérieur du tube 29 qui sert de ridelle. 24 is the tube which, with the tube 1 1 is used for fixing the floor which receives passengers or goods to be transported. 25 is a roll bar which also serves for fixing a superior protection against the sun or the rain. The plug 27 is used to fill the tube 4, 2, 3 with fuel. For a good fuel supply to the engine, the leg 4 is significantly higher than, the leg 3, the latter having the breather outlet 28 at its end, this breather can be a flexible tube integral with the socket 28, this flexible tube rising inside the tube 29 which serves as a side wall.

30 est le pignon qui est solidaire de l'arbre de sortie de la transmission du moteur, 31 est le pignon qui est solidaire de l'axe de la roue motrice 14, 32 est la chaine de transmission.30 is the pinion which is integral with the output shaft of the engine transmission, 31 is the pinion which is integral with the axis of the drive wheel 14, 32 is the transmission chain.

Sans rien changer au caractère de l'inveition il est possible de rendre également motrice l'autre roue arrière 15, ceci en montant le pignon 30 sur une roue libre, l'arbre de sortie de la transmission moteur étant également relié par un cardan à la partie interne d'une autre roue libre fixée par des paliers sur le bras 13, la partie externe de cette roue libre ayant un pignon relié par chaine à l'axe de la roue 15. Il est également possible d'équiper le bras 13 d'un moteur avec pignon 30, chaine 32 et pignon 31 sur l'axe de la roue 15.Avoir les deux roues arrières motrices augmente la maniabilité du tricycle, par contre le poids à vide et surtout les couts sont considérablement augmentés; pour des conditions normales d'utilisation, une seule roue motrice est amplement suffisante, comme deux roues motrices sont généralement suffisante pour une automobile normale. 32 sont les tubes qui reçoivent le protège jambes 33. 34 est le garde boue de la roue avant, 35 est la bavette du garde boue.34; il est aisé de voir que , à l'arret, le conducteur peut mettre les pieds au sol entre le tube 1 1 et le protège jambes 33 et éffectuer, par propulsion pédestre, des petites manoeuvres comme une marche arrière, ceci sans etre gêné par le chassis ou le support du siège. 36 et 37 sont les suspensions élastiques des roues arrières 14 et 15; la suspension 37 de la roue non motrice est reliée au tube entretoise 38 qui relie le tube 11 au jambage 4, ce tube 38 est utile à cause de la plus grande hauteur du jambage 4 par rapport au sol. Without changing the character of the invention, it is also possible to make the other rear wheel 15 also drive, by mounting the pinion 30 on a free wheel, the output shaft of the engine transmission also being connected by a cardan joint. the internal part of another free wheel fixed by bearings on the arm 13, the external part of this free wheel having a pinion connected by chain to the axis of the wheel 15. It is also possible to equip the arm 13 a motor with pinion 30, chain 32 and pinion 31 on the axis of the wheel 15. Having the two rear driving wheels increases the maneuverability of the tricycle, on the other hand the unladen weight and above all the costs are considerably increased; for normal conditions of use, a single drive wheel is more than sufficient, as two drive wheels are generally sufficient for a normal automobile. 32 are the tubes which receive the leg protector 33. 34 is the mudguard of the front wheel, 35 is the mud flap of the mudguard. 34; it is easy to see that, when stopped, the driver can put his feet on the ground between the tube 1 1 and the leg protector 33 and carry out, by pedestrian propulsion, small maneuvers such as reverse, without being hampered by the chassis or the seat support. 36 and 37 are the elastic suspensions of the rear wheels 14 and 15; the suspension 37 of the non-driving wheel is connected to the spacer tube 38 which connects the tube 11 to the leg 4, this tube 38 is useful because of the greater height of the leg 4 relative to the ground.
