Abstract
Movable set for thermal engines and piston machines. The disclosed device replaces the conventional transmission: rod-crankshaft by using a single oscillating rod and a single diagonal throw for any number of pistons or members with an alternating rectilinear translation motion. The throw axis sweeps a revolution cone. The rod, of fixed axis, is hinged, on the one hand, through its head with a crankshaft and, on the other hand, with parts having an alternating motion such as double-head pistons respectively through orthogonal arms of which the extremities operate in the axial area of those parts. The device with a reduced number of moving parts is very compact. It transmits a higher voluminal power and a higher power per unit of mass. The passage of the pistons at the center points being slower, the control of combustion and pollution is facilitated.
Description
TITRE : EQUIPAGE MOBILE : MOTEURS THERMIQUES, MACHINES A PISTONS TITLE: MOBILE EQUIPMENT: HEAT ENGINES, PISTON MACHINES
La présente invention concerne l'équipage mobile des moteurs thermiques à pistons à deux temps, quatre temps, à bougies ou Diesel et toute machine convertissant un mouvement alternatif en rotation continue et réciproquement. The present invention relates to the mobile assembly of two-stroke, four-stroke, spark plug or diesel piston engines and any machine converting an alternating movement into continuous rotation and vice versa.
L'équipage mobile des moteurs actuels à bielle et vilebrequin classiques est volumineux, lourd, siège de vibrations nuisibles et de frottements produisant une ovalisation des cylindres et une perte d'énergie. The mobile equipment of current conventional rod and crankshaft engines is bulky, heavy, seat of harmful vibrations and friction producing an ovalization of the cylinders and a loss of energy.
Le dispositif selon l'invention atténue ces inconvénients. Il comporte en effet- une seule "bielle" oscillante, munie de bras dont les extrémités s'articulent sur des pistons en nombre quelconque, à simple ou double tête. Elle exerce un couple de forces sur un seul "maneton" diagonal d'un vilebrequin simplifié. Ce vilebrequin (fig. 1) comporte un arbre de sortie 7, avec un volant d'inertie 6, d'axe XX, deux tourillons 3 de même axe, deux bras de manivelle 2, un maneton 1 diagonal dont l'axe AOA coupe XOX en 0 et deux contrepoids 5 équilibrant les bras de manivelle et le maneton. Au cours de la rotation du vilebrequin, l'axe AOA balaye un cône de révolution de sommet 0 et d'angle AOX =α . Ce vilebrequin est porté par les paliers- support 4. Dans le volume de centre C, limité partiellement par les bras de manivelle et les contrepoids, est logée la tête de la bielle d'axe fixe YOY. The device according to the invention mitigates these drawbacks. It in fact comprises a single oscillating "connecting rod", provided with arms whose ends are articulated on pistons in any number, with single or double head. It exerts a couple of forces on a single diagonal "crankpin" of a simplified crankshaft. This crankshaft (fig. 1) comprises an output shaft 7, with a flywheel 6, of axis XX, two journals 3 of the same axis, two crank arms 2, a crank pin 1 diagonal whose axis AOA cuts XOX in 0 and two counterweights 5 balancing the crank arms and the crankpin. During the rotation of the crankshaft, the axis AOA sweeps a cone of revolution with vertex 0 and angle AOX = α. This crankshaft is carried by the support bearings 4. In the center volume C, partially limited by the crank arms and the counterweights, is housed the head of the rod of fixed axis YOY.
La bielle portée par le palier-pivot 11 se compose de trois parties : un arbre 8, une tête 9, des bras 10. Le mouvement de la bielle est une oscillation d'amplitude autoιτ de YOY orthogonal à XOX. Au cours de cette oscillation, l'axe OZ (fig. 2A) lié à la bielle et perpendiculaire à OY balaye un angle 2 α dont la bissectrice est OX. Cette oscillation de la bielle provoque la mise en mouvement du maneton selon un cône de sommet O et d'angle α. Ce mouvement conique du maneton implique la rotation continue autour de l'axe XOX des bras de manivelle. Dans le mouvement relatif du maneton dans la bielle, OA reste dans le plan YOZ et A décrit un arc de méridien a égal à 2 α , de bissectrice OZ. La tête de bielle 9 (fig. 1, 2A, 2B) s'inscrit dans une sphère S de centre O et de diamètre légèrement inférieur à la longueur du maneton. Une cavité v, ménagée dans S, est balayée par le maneton au cours de son oscillation. Ses parois P
latérales sont symétriques par rapport au plan YOZ et sont écartées l'une de l'autre d'une distance égale au diamètre du maneton, augmentée du jeu nécessaire à la lubrification. La sphère S sera aussi allégée de toute matière non nécessaire à la transmission des forces et dont l'élimination ne nuit pas à la rigidité de la pièce. The connecting rod carried by the pivot bearing 11 consists of three parts: a shaft 8, a head 9, arms 10. The movement of the connecting rod is an amplitude oscillation autoιτ of YOY orthogonal to XOX. During this oscillation, the axis OZ (fig. 2A) linked to the connecting rod and perpendicular to OY scans an angle 2 α whose bisector is OX. This oscillation of the connecting rod causes the crankpin to move according to a cone with vertex O and angle α. This conical movement of the crankpin involves the continuous rotation around the XOX axis of the crank arms. In the relative movement of the crankpin in the connecting rod, OA remains in the plane YOZ and A describes an arc of meridian a equal to 2 α, of bisector OZ. The connecting rod head 9 (fig. 1, 2A, 2B) fits into a sphere S of center O and of diameter slightly less than the length of the crank pin. A cavity v, formed in S, is swept by the crankpin during its oscillation. Its walls P lateral are symmetrical with respect to the YOZ plane and are spaced from each other by a distance equal to the diameter of the crankpin, increased by the clearance necessary for lubrication. The sphere S will also be lightened of any material not necessary for the transmission of forces and the elimination of which does not affect the rigidity of the part.
La bielle est portée par un palier-pivot 11 ou une butée, éliminant tout mouvement selon la direction YY. The connecting rod is carried by a pivot bearing 11 or a stop, eliminating any movement in the direction YY.
L'arbre de bielle 8 est positionné par les paliers 12 qui maintiennent fixe l'axe YY. Muni de bras transversaux 10 dont les extrémités s'engagent dans les pistons 13, il transmet les forces entre pistons et tête de bielle. Percé de canalisations, il conduit le lubrifiant injecté à ses extrémités jusqu'au maneton et aux pistons. The connecting rod shaft 8 is positioned by the bearings 12 which hold the YY axis fixed. Provided with transverse arms 10, the ends of which engage in the pistons 13, it transmits the forces between the pistons and the connecting rod head. Drilled with pipes, it conducts the lubricant injected at its ends to the crank pin and the pistons.
Les pistons ont une forme inscrite dans un cylindre de révolution. Ils comprennent essentiellement (fig. 3A et 3B) : - les têtes situées aux extrémités de ce cylindre, portant The pistons have a shape inscribed in a cylinder of revolution. They essentially include (fig. 3A and 3B): - the heads located at the ends of this cylinder, bearing
des cannelures pour les segments d'étanchéité, les pare-feu et les racleurs d'huile (repérés 26), splines for the sealing rings, firebreaks and oil scrapers (marked 26),
- le corps du piston 13 reliant et solidarisant les 2 têtes, - the body of the piston 13 connecting and joining the 2 heads,
percé d'une lumière 20 dans sa partie centrale où s'engage et travaille l'extrémité des bras de bielle. pierced with a light 20 in its central part where engages and works the end of the connecting rod arms.
L'extrémité des bras est un corps de révolution, cylindrique par exemple, s'appuyant avec le jeu nécessaire sur les parois de la lumière 20. The end of the arms is a body of revolution, cylindrical for example, resting with the necessary clearance on the walls of the lumen 20.
La longueur des bras est telle que les points de contact sur les parois de la lumière sont situés sur l'axe du piston lorsque les forces de détente des gaz sont maximales : le couple exercé sur le piston est alors nul et ne produit pas d'ovalisation des cylindres. The length of the arms is such that the contact points on the walls of the lumen are located on the axis of the piston when the gas expansion forces are maximum: the torque exerted on the piston is then zero and does not produce any ovalization of the cylinders.
Les pistons 13, à simple ou double tête, en nombre quelconque (le nombre quatre a été choisi dans la description et les dessins), ont leurs axes situés dans des plans perpendiculaires à YOY. Les quatre pistons sont disposés en deux étages superposés de centres 01 et 02 (fig. 1). La figure 3A représente un étage de deux pistons opposés, à double tête, se mouvant dans les cylindres 18 dont les bases reçoivent les culasses 19. Une fenêtre dans la partie centrale des cylindres permet le passage et l'oscillation de l'arbre et du bras de bielle. Cette fenêtre est repérée 25 (fig. 3A).
Chaque cylindre est refroidi par un fluide circulant à sa périphérie et chaque piston est refroidi et lubrifié par un liquide injecté au niveau de la partie centrale du cylindre ou du piston. Les contacts mobiles seront lubrifiés par des canalisations ménagées dans la bielle, le maneton, le vilebrequin et les pistons. The pistons 13, single or double head, in any number (the number four has been chosen in the description and the drawings), have their axes located in planes perpendicular to YOY. The four pistons are arranged in two superposed stages with centers 01 and 02 (fig. 1). FIG. 3A represents a stage of two opposite pistons, with double heads, moving in the cylinders 18, the bases of which receive the cylinder heads 19. A window in the central part of the cylinders allows the passage and the oscillation of the shaft and of the connecting rod arm. This window is marked 25 (fig. 3A). Each cylinder is cooled by a fluid circulating at its periphery and each piston is cooled and lubricated by a liquid injected at the central part of the cylinder or the piston. The moving contacts will be lubricated by pipes made in the connecting rod, the crankpin, the crankshaft and the pistons.
