Description

Moteur a explosions avec parties thermiques de moto La présente invention concerne les moteurs a explosions du type quatre temps de plus de quatre cylindres. The present invention relates to four-stroke type explosion engines with more than four cylinders.
Les moteurs connus présentent l'inconvénient d'être lourds et encombrants sauf,pour les moteurs de compétition qui eux présentent l'inconvénient d'être d'un prix très élevéKnown engines have the drawback of being heavy and bulky except, for competition engines which have the drawback of being very expensive
Le moteur selon l'invention présente un rapport,poids encombrement prix et rendement très intéressant.The motor according to the invention has a very attractive ratio, weight, size, price and efficiency.
Ce moteur comprend deux parties,le haut moteur composé de parties thermiques de moto (chaque partie thermique com¬ prend un ensemble de quatre cylindres avec bielles pistons culasses et carburateurs) et le bas moteur composé d'un ou plusieurs carters en alliage léger avec les vilebrequins et arbres de transmission. L'originalité de ce moteur consiste dans le montage de deux,quatre ou six parties thermiques de moto dans un même bas moteur avec plusieurs vilebrequins reliés entre eux par des engrenages. "' -This engine comprises two parts, the high engine composed of thermal motorcycle parts (each thermal part includes a set of four cylinders with piston rods, cylinder heads and carburetors) and the low engine composed of one or more light alloy casings with crankshafts and transmission shafts. The originality of this engine consists in the assembly of two, four or six thermal parts of motorcycle in the same low engine with several crankshafts connected to each other by gears. "' -
Selon une forme de réalisation le bas moteur comprend un carter avec un plan de joint horizontal passant par l'axe des vilebrequins permettant le démontage.According to one embodiment the low engine comprises a casing with a horizontal joint plane passing through the axis of the crankshafts allowing disassembly.
Le carter comprend plusieurs paliers pour le montage de deux vilebrequins sur coussinets,les vilebrequins sont para¬ llèles et reliés par des engrenages taillés sur ces derniers, l'un deux comprend une prise de force a son extrémité prévue pour recevoir un enbrayage.The casing comprises several bearings for mounting two crankshafts on bearings, the crankshafts are para¬ lleles and connected by gears cut on the latter, one of which comprises a power take-off at its end designed to receive a clutch.
Sur la partie supérieure du carter deux plans de joint parallèles a l'axe des vilebrequins et inclinés vers l'exté¬ rieur reçoivent les parties thermiques,les arbres a cames sont entrainés par les vilebrequins par l'intermédiaire de chaines.On the upper part of the casing, two joint planes parallel to the axis of the crankshafts and inclined towards the outside receive the thermal parts, the camshafts are driven by the crankshafts by means of chains.
Cet ensemble forme un moteur en v avec deux rangées de quatre cylindres.This assembly forms a v-shaped engine with two rows of four cylinders.
La figure 1 représente le bas moteur dont la coupe A-A se situe au niveau du plan de joint de démontage et permet de voir les deux vilebrequins avec les engrenages taillés dans la masse ainsi que la prise de force (5),les manetons de bielle sont représentés par un axe (9). Pour la clarté des dessins les coussinets,les bagues d'étanchéité,le circuit de graissage et d'allumage,ne sont pas représentés car ils ne comportent aucun caractère particulier. Selon le même procédé un carter plus long dans le sens de l'axe des vilebrequins reçoit quatre groupes thermiques ali¬ gnés deux par deux,les vilebrequins plus longs comportent huit manetons de bielle chacun.FIG:4.Figure 1 shows the low engine whose AA cut is located at the disassembly joint plane and allows to see the two crankshafts with the gears cut in the mass as well as the PTO (5), the crank pins are represented by an axis (9). For clarity of the drawings, the bearings, the sealing rings, the lubrication and ignition circuit are not shown because they do not have any particular character. According to the same process a longer casing in the direction of the axis of the crankshafts receives four thermal groups ali¬ born two by two, the longer crankshafts comprise eight connecting rod crankshafts each.FIG: 4.
Ce moteur comporte 16 cylinrdes en v avec la prise de for ce a l'extrémité de l'un des deux vilebrequins. La fig.3 représente le même type de moteur 16 cylindres avec une prise de force différente,dans ce cas le carter est aménagé de façon a recevoir un arbre de transmission au centreThis engine has 16 v-cylinders with the power take-off at the end of one of the two crankshafts. Fig.3 shows the same type of 16-cylinder engine with a different PTO, in this case the casing is arranged to receive a drive shaft in the center
Cet arbre se situe sur le même plan que les vilebrequins et perpendiculaire a ceux-ci,l'arbre comporte deux engrenages coniques et une prise de force, des roulements ou des coussi¬ nets sont prévus pour assurer son mouvement.This shaft is located on the same plane as the crankshafts and perpendicular thereto, the shaft has two bevel gears and a PTO, bearings or coussi¬ nets are provided to ensure its movement.
Les vilebrequins sont au nombre de quatre et disposent chacun de quatre manetons,deux d'entre eux sont munfs -cl'un engrenage conique a leur extrémité situé vers le centre du moteur,ces engrenages entraînent l'arbre de transmission.The crankshafts are four in number and each have four crankpins, two of them are provided with a bevel gear at their end located towards the center of the engine, these gears drive the transmission shaft.
Selon le même principe un autre procédé de disposition des parties thermiques consiste en ce que le carter pré-cité comme moteur de base comporte dans ce cas deux encoches situ¬ ées de chaque côté dans un plan de joint vertical et parallèle a l'axe des villebrequins. FIG:5According to the same principle, another method of arranging the thermal parts consists in that the housing mentioned above as basic motor in this case comprises two notches located on each side in a vertical joint plane parallel to the axis of the Villebrequins. FIG: 5
Sur chaque plan de joint vient s'ajuster un autre carter qui possède un vilebrequin et un arbre intermédiaire muni d'un engrenage.On each joint plane is adjusted another casing which has a crankshaft and an intermediate shaft provided with a gear.
Ce moteur comporte donc un carter central et deux carters latéraux.This engine therefore comprises a central casing and two lateral casings.
A l'intérieur du carter central il y a deux vilebrequins, chacun d'eux possède trois engrenages et quatre manetons de bielle.Inside the central housing there are two crankshafts, each of them has three gears and four connecting rods.
Les vilebrequins des carters latéraux sont munis d'un seul engrenage aligné avec celui de l'arbre intermédiaire lui même aligné avec un de ceux des vilebrequins de la partie centrale, les encoches prévues a cet effet permettent la liaison entre les quatre vilebrequins,les quatre parties thermiques sont disposées parallèlement entre elles dans le même sens que les axes des vilebrequins. FIG.2 Numérotation des pièces :(l)culasse (2)cylindreThe crankshafts of the side casings are provided with a single gear aligned with that of the intermediate shaft itself aligned with one of those of the crankshafts of the central part, the notches provided for this purpose allow the connection between the four crankshafts, the four thermal parts are arranged parallel to each other in the same direction as the axes of the crankshafts.
