Description

Domaine TechniqueTechnical area

L'invention concerne un moteur à pistons axiaux à chambre de balayage comprimée, pour tous les moyens de transport ou groupes énergétiques.The invention relates to an axial piston engine with compressed sweeping chamber, for all means of transport or energy groups.

Technique AnterieurePrevious Technique

On connaît des moteurs à combustion interne à plusieurs cylindres à pistons axiaux dans lesquels les pistons sont placés deux par deux dans le même cylindre, la bande d'appui qui empêche la rotation de l'oscillateur est fixée et l'échange de gaz se réalise par l'intermédiaire des fenêtres de balayage qui mettent en liaison directe le cylindre avec l'espace de précompression qui peut être réalisé par un compresseur disposé dans un plan adjacent au moteur. Parmi ceux-ci on peut aussi citer le moteur à pistons axiaux à deux temps décrit dans le brevet AT-B-73073, où l'arbre principal est utilisé comme réservoir intermédiaire pour l'air nécessaire au balayage, et aussi comme réservoir intermédiaire pour le mélange frais air-combustible. Tous ces moteurs présentent l'inconvénient qu'ils ne résolvent pas le problème d'une liberté fonctionnelle totale contrôlée de la bielle et du guidage de l'oscillateur. En outre, ces solutions n'assurent pas un échange de gaz qui réalise un rendement volumétrique élevé, n'assurent pas une pression de balayage satisfaisante et/ou mettent en mouvement de rotation des pièces à dimensions et masses assez grandes.There are known internal combustion engines with several cylinders with axial pistons in which the pistons are placed two by two in the same cylinder, the support strip which prevents the rotation of the oscillator is fixed and the gas exchange takes place by means of the scanning windows which put the cylinder in direct connection with the precompression space which can be produced by a compressor arranged in a plane adjacent to the engine. Among these we can also cite the two-stroke axial piston engine described in patent AT-B-73073, where the main shaft is used as an intermediate tank for the air required for sweeping, and also as an intermediate tank for the fresh air-fuel mixture. All these motors have the disadvantage that they do not solve the problem of controlled total functional freedom of the connecting rod and of the guidance of the oscillator. In addition, these solutions do not provide a gas exchange which achieves a high volumetric efficiency, do not provide a satisfactory scanning pressure and / or set in rotation movement of parts with fairly large dimensions and masses.

Exposé de L'inventionPresentation of the invention

Le moteur axial à deux temps, conforme à la présente invention, élimine les inconvénients mentionnés ci-dessus par le fait qu'afin d'assurer une optimisation de l'échange des gaz qui doit engendrer un rendement volumétrique élevé et assurer le mouvement libre du système bielle- oscillateur, l'admission du mélange propre se fait directement dans une chambre de balayage, par l'intermèdiaire d'une fenêtre d'admission pratiquée à la partie inférieure du cylindre et actionnée par l'arbre primaire qui est pourvu de deux canaux longitudinaux, le melange propre étant, sous l'action du piston, refoulé de la chambre de balayage à l'aide d'une fenêtre de balayage, à l'intérieur d'une chambre de combustion; entre la chambre de balayage et l'enceinte du carter est monté un séparateur, constitué d'une boîte fixée sur le bloc moteur, d'un premier manchon sphérique monté entre le raccord mobile et la boîte, et d'un deuxième manchon sphérique monté entre le raccord mobile et le corps de la bielle; entre le premier manchon sphérique et le raccord mobile et entre le deuxième manchon sphérique et la boîte est monté un joint annulaire d'étanchéité; afin d'éviter le blocage de l'oscillateur, on a monté dans le corps de l'oscillateur une fourche ayant des possibilités de rotation et un rail de guidage, sur lequel la fourche coulisse, est assemblé dans le bloc moteur dans deux paliers qui lui confèrent aussi des possibilités de rotation.The two-stroke axial motor, in accordance with the present invention, eliminates the drawbacks mentioned above by the fact that in order to ensure an optimization of the exchange of gases which must generate a high volumetric efficiency and ensure the free movement of the rod-oscillator system, the admission of the clean mixture is done directly in a sweeping chamber, through an admission window made at the bottom of the cylinder and actuated by the primary shaft which is provided with two longitudinal channels, the clean mixture being, under the action of the piston, discharged from the scanning chamber using a scanning window, inside a combustion chamber; between the sweeping chamber and the enclosure of the housing is mounted a separator, consisting of a box fixed on the engine block, a first spherical sleeve mounted between the movable connector and the box, and a second spherical sleeve mounted between the movable connector and the body of the connecting rod; between the first spherical sleeve and the movable connector and between the second spherical sleeve and the box is mounted an annular seal; in order to avoid blocking of the oscillator, a fork with rotational possibilities has been mounted in the oscillator body and a guide rail, on which the fork slides, is assembled in the engine block in two bearings which also give it rotation possibilities.

Meilleure Manière de Realiser L'inventionBest Way to Realize the Invention

Le moteur axial à deux temps, qui fait l'objet de la présente invention est constitué d'un arbre primaire A monté parallèllement à des cylindfes moteurs 1 dans lesquels travaillent deux pistons 2 qui forment entre eux une chambre de combustion a, pistons qui sont assemblés par une articulation sphérique b avec des bielles B qui oscillent pendant le fonctionnement. Un séparateur C divise en deux parties l'enceinte d'un carter déjà connu.The two-stroke axial motor which is the subject of the present invention consists of a primary shaft A mounted parallel to the engine cylinders 1 in which work two pistons 2 which form between them a combustion chamber a, pistons which are assembled by a ball joint b with connecting rods B which oscillate during operation. A separator C divides the enclosure of an already known casing into two parts.

A l'autre bout, les bielles B sont assemblées, toujours à l'aide d'une articulation sphérique c avec un oscillateur D.At the other end, the connecting rods B are assembled, still using a ball joint c with an oscillator D.

Le moteur axial comporte aussi un sous-ensemble E qui guide l'oscillateur. L'arbre primaire A qui assure la commande de l'échange de gaz et transmet à l'extérieur le couple moteur, est constitué de quatre tronçons 3, 4, 5 et 6, qui sont montés à l'aide de coins 7 et de vis de serrage 8, de manière à pouvoir être démontés.The axial motor also includes a sub-assembly E which guides the oscillator. The primary shaft A which ensures the control of the gas exchange and transmits the engine torque to the outside, consists of four sections 3, 4, 5 and 6, which are mounted using wedges 7 and clamping screw 8, so that it can be removed.

Dans le tronçon central 4 de l'arbre primaire A, il y a au moins deux canaux longitudinaux d sur les mêmes génératrices qui assurent l'admission de l'air frais ou du mélange de combustibles du collecteur d'admission, déjà connu et représenté sur les dessins. L'air ou le mélange frais du collecteur d'admission passe par une fenêtre pratiquée dans le bloc cylindre déjà connu pour aboutir à un espace annulaire e créé par un saut du diamètre f du tronçon 4 de l'arbre primaire A.In the central section 4 of the primary shaft A, there are at least two longitudinal channels d on the same generators which ensure the admission of fresh air or the fuel mixture from the intake manifold, already known and shown in the drawings. The fresh air or mixture from the intake manifold passes through a window in the already known cylinder block to reach an annular space e created by a jump in the diameter f of the section 4 of the primary shaft A.

De l'espace cylindrique e, l'air ou le mélange frais circule seulement quand les canaux d arrivent en face des fenêtres d'admission g dans des chambres de balayage h. Ainsi, l'arbre primaire A commande l'aspiration de l'air ou du mélange frais dans la chambre de balayage h où toute la quantité d'air ou de mélange aspirés est retenue, ce que engendre une augmentation du rendement volumétrique élevé. De la chambre de balayage h, la charge fraîche pénètre dans la chambre de combustion a du cylindre 1 par les fenêtres de balayage i actionnées par les pistons 2.From the cylindrical space e, the fresh air or mixture circulates only when the channels d arrive opposite the intake windows g in the scanning chambers h. Thus, the primary shaft A controls the suction of fresh air or mixture into the sweeping chamber h where the entire quantity of air or mixture sucked in is retained, which generates an increase in the high volumetric efficiency. From the scanning chamber h, the fresh charge enters the combustion chamber a of the cylinder 1 through the scanning windows i actuated by the pistons 2.

Sous l'action de la charge fraîche qui s'écoule, on réalise le balayage du cylindre, les gaz brûlés étant évacués par les fenêtres d'échappement j.Under the action of the fresh charge flowing, the cylinder is scanned, the burnt gases being evacuated through the exhaust windows j.

La bielle B est constituée d'une tige ronde 9 d'un élement sphérique 10 qui travaille dans l'articulation sphérique b s'assemblant avec le piston 2, de l'articulation sphérique c et de l'oscillateur D. Pendant le fonctionnement, la bielle B décrit un mouvement spatial, générant une surface conique ayant une coupe elliptique, le mouvement spatial de la bielle B étant déterminé par le guidage E, par des jeux dans des paliers sphériques k par lesquels on a assemblé sur l'arbre primaire A les deux oscillateurs D, et par des défauts inhérents apparus au cours du montage des tronçons 3, 4, et 6 de l'arbre primaire A.The connecting rod B consists of a round rod 9 of a spherical element 10 which works in the spherical joint b joining with the piston 2, the spherical joint c and the oscillator D. During operation, the connecting rod B describes a spatial movement, generating a conical surface having an elliptical section, the spatial movement of the connecting rod B being determined by the guide E, by games in spherical bearings k by which the two oscillators have been assembled on the primary shaft A D, and by inherent faults which appeared during the mounting of sections 3, 4, and 6 of the primary shaft A.

Le séparateur C confère une mobilité pendulaire et de translation de la bielle B et est constitué d'une boîte 11 fixée sur le bloc moteur déjà connu, d'un premier manchon sphérique 12 monté entre la boîte 11 et un raccord mobile 13 et d'un manchon sphérique 14 monté entre le raccord mobile 13 et la tige ronde 9. Entre le manchon sphérique 14 et le raccord mobile 13 et entre le manchon sphérique 12 et la boîte 11, il y a des joints annulaires 15 et 16.The separator C provides pendular and translational mobility of the connecting rod B and consists of a box 11 fixed to the already known engine block, a first spherical sleeve 12 mounted between the box 11 and a movable connector 13 and a spherical sleeve 14 mounted between the movable connector 13 and the round rod 9. Between the spherical sleeve 14 and the movable connector 13 and between the spherical sleeve 12 and the box 11, there are annular seals 15 and 16.

Afin d'assurer un mouvement de translation léger entre la tige ronde 9 et la surface intérieure de forme cylindrique du manchon sphérique 14, sur la surface intérieure cylindrique du manchon, on a monté un matériau anti-friction, par exemple un alliage en bronze.In order to ensure a slight translational movement between the round rod 9 and the cylindrical interior surface of the spherical sleeve 14, on the cylindrical interior surface of the sleeve, an anti-friction material, for example a bronze alloy, has been mounted.

Afin de maintenir l'étanchéité de la chambre de balayage h on recommande que la tige ronde 9 et la surface intérieure cylindrique du manchon sphérique 14 soient usinées de manière convenable. Par sa construction bi-articulée, le séparateur C assure la division de l'espace correspondant à chaque piston en deux espaces, la chambre de balayage h et l'enceinte d'un carter déjà connu.In order to maintain the tightness of the scanning chamber h it is recommended that the round rod 9 and the cylindrical interior surface of the spherical sleeve 14 be suitably machined. By its bi-articulated construction, the separator C divides the space corresponding to each piston into two spaces, the scanning chamber h and the enclosure of an already known casing.

La séparation de l'espace du carter et de la chambre de balayage h engendre une augmentation du rendement de remplissage de même qu'un meilleur balayage de l'enceinte du cylindre 1 par le pénétration dans les deux sens du mélange frais existant sous pression dans la chambre de balayage h par les fenêtres de balayage i.The separation of the space of the casing and the sweeping chamber h generates an increase in the filling efficiency as well as a better sweeping of the enclosure of the cylinder 1 by the penetration in both directions of the fresh mixture existing under pressure in the scanning chamber h through the scanning windows i.

L'oscillateur D est constitué d'un corps formé par deux flasques 17, des boulons 18 disposés radialement par rapport au corps et qui font la liaison entre le corps de l'oscillateur D et les éléments sphériques 19, qui forment avec les cages à cavité sphérique 20 et le coussinet 21 les articulations sphériques C, et d'un coussinet sphérique 22, d'une boîte-palier maneton 23, d'un coussinet-palier maneton 24 et des vis de serrage 25.The oscillator D consists of a body formed by two flanges 17, bolts 18 arranged radially relative to the body and which make the connection between the body of the oscillator D and the spherical elements 19, which form with the cages at spherical cavity 20 and the bearing 21 the spherical joints C, and of a spherical bearing 22, of a crankpin bearing housing 23, of a crankpin bearing bearing 24 and of the clamping screws 25.

Le coussinet palier sphérique 22 est réalisé en un matériau anti-friction qui permet l'oscillation légère du corps de l'oscillateur D sur la tête sphérique / du tronçon 5 de l'arbre primaire A. La boîte-palier maneton 23 est fixée par des vis de serrage 25 sur le corps de l'oscillateur D et constitue le support du coussinet palier maneton 24 qui peut assumer tous les efforts, tant radiaux, qu'axiaux.The spherical bearing cushion 22 is made of an anti-friction material which allows the slight oscillation of the body of the oscillator D on the spherical head / of the section 5 of the primary shaft A. The crankpin bearing box 23 is fixed by clamping screws 25 on the body of the oscillator D and constitutes the support for the crank pin bearing 24 which can assume all the forces, both radial and axial.

L'oscillateur D est un sous-ensemble du moteur qui supporte les plus grandes sollicitations meca- niques parce qu'il transforme le mouvement de translation des pistons 2 en mouvement de rotation de l'arbre primaire A à l'aide d'un palier maneton m formé du coussinet-palier maneton 24 de la partie cylindrique du tronçon 5 de l'arbre primaire A et du palier sphérique k formé de la tête sphérique / et du coussinet-palier sphérique 22.Oscillator D is a sub-assembly of the motor which withstands the greatest mechanical stresses because it transforms the translational movement of the pistons 2 into the rotational movement of the primary shaft A using a bearing crank pin m formed by the bearing bearing crank pin 24 of the cylindrical part of the section 5 of the primary shaft A and the spherical bearing k formed by the spherical head / and by the spherical bearing 22.

Afin de prévenir la rotation de l'oscillateur D en même temps que l'arbre primaire A, on a monté à la partie inférieure du carter un système de guidage E constitué d'une fourche 26 montée de manière qu'elle ait la possibilité de rotation dans le corps de l'oscillateur sur un rail de guidage 27 qui est montée dans deux paliers radiaux 28 ce qui lui confère la possibilité de rotation. Le système de guidage E confère à l'oscillateur la liberté de mouvement et lui permet d'assumer les éventuels déplacements pendulaires de l'oscillateur.In order to prevent the oscillator D from rotating at the same time as the primary shaft A, a guide system E consisting of a fork 26 mounted so that it has the possibility of being mounted at the bottom of the casing rotation in the body of the oscillator on a guide rail 27 which is mounted in two radial bearings 28 which gives it the possibility of rotation. The guidance system E gives the oscillator freedom of movement and allows it to assume any pendulum movements of the oscillator.
