On a montré en figures 1 à 3 un bloc moteur 100 qui comprend au moins un cylindre 110 dans lequel se déplace un piston 2 au moyen d'un dispositif de transmission 1.FIGS. 1 to 3 show an engine block 100 which comprises at least one cylinder 110 in which a piston 2 moves by means of a transmission device 1.
Le dispositif de transmission mécanique 1 comporte dans la partie inférieure du piston 2 un organe de transmission 3 solidaire dudit piston et coopérant, d'une part avec un dispositif de guidage à roulement 4, et d'autre part avec une roue dentée 5.The mechanical transmission device 1 comprises in the lower part of the piston 2 a transmission member 3 integral with said piston and cooperating, on the one hand with a rolling guide device 4, and on the other hand with a toothed wheel 5.
La roue dentée 5 coopère avec une bielle 6 reliée à un vilebrequin 9 afin de réaliser la transmission du mouvement entre ledit piston et ledit vilebrequin.The toothed wheel 5 cooperates with a connecting rod 6 connected to a crankshaft 9 in order to effect the transmission of movement between said piston and said crankshaft.
La roue dentée 5 coopère à l'opposé de l'organe de transmission 3 avec une autre crémaillère dite crémaillère de commande 7 dont la position verticale par rapport au bloc moteur 100 est pilotée par un dispositif de contrôle 12 comportant un vérin de commande 8, dont le piston de vérin 13 est guidé dans un cylindre de vérin 112 aménagé dans le bloc moteur 100. Le cylindre de vérin 112 peut être directement alésé dans le bloc moteur 100, ou dans une chemise non représentée rapportée dans le bloc moteur 100. Le cylindre de vérin 112 est fermé dans sa partie supérieure par une culasse de vérin 113 qui est vissée sur le bloc moteur 100. Il peut être prévu une culasse 113 par cylindre de vérin 112 ou une culasse 113 commune à l'ensemble des cylindres de vérin 112 d'un moteur multicylindres.The toothed wheel 5 cooperates opposite the transmission member 3 with another rack known as a control rack 7 whose vertical position relative to the engine block 100 is controlled by a control device 12 comprising a control cylinder 8, whose cylinder piston 13 is guided in a cylinder cylinder 112 arranged in the engine block 100. The cylinder cylinder 112 can be directly bored in the engine block 100, or in a jacket not shown attached to the engine block 100. The cylinder 112 is closed in its upper part by a cylinder head 113 which is screwed onto the engine block 100. There may be provided a cylinder head 113 by cylinder 112 or a cylinder head 113 common to all of the cylinder cylinders 112 of a multi-cylinder engine.
Le dispositif de transmission 1 comporte un organe de transmission 3 solidaire du piston 2 et pourvu sur l'une de ses faces d'une première crémaillère de forte dimension 35 dont les dents 34 coopèrent avec celles 51 de la roue dentée 5. L'organe de transmission 3 comporte, à l'opposé de la crémaillère 35, une autre crémaillère 37 dont les dents 38 de faible dimension coopèrent avec celles du rouleau 40 du dispositif de guidage à roulement A solidaire du bloc moteur.The transmission device 1 comprises a transmission member 3 secured to the piston 2 and provided on one of its faces with a first large rack 35 whose teeth 34 cooperate with those 51 of the toothed wheel 5. The transmission member 3 comprises, opposite the rack 35, another rack 37, the teeth 38 of small dimension cooperate with those of the roller 40 of the rolling guide device A secured to the engine block.
Le bloc moteur 100 est percé d'un orifice 104 du côté du cylindre 110 permettant d'introduire dans ledit bloc un support 41 comportant des crémaillères 46 assurant la synchronisation du déplacement du rouleau -40 avec celui du piston 2, et une piste de roulement 48 coopérant avec le rouleau 40.The engine block 100 is pierced with an orifice 104 on the side of the cylinder 110 making it possible to introduce into said block a support 41 comprising racks 46 ensuring synchronization of the movement of the roller -40 with that of the piston 2, and a rolling track 48 cooperating with the roller 40.
Le support 41 est constitué d'une plaque de forte épaisseur 42 qui permet sa fixation au bloc moteur 100, par l'extérieur de ce dernier, au moyen de vis 105.The support 41 consists of a very thick plate 42 which allows it to be fixed to the engine block 100, from the outside of the latter, by means of screws 105.
Pour faciliter l'usinage des crémaillères 46 sur le support 41 , on peut rapporter sur ledit support 41 un corps 45 comportant la piste de roulement 48 coopérant avec le rouleau 40, ledit corps étant fixé audit sup ort 41 avec au moins une vis de fixation 107.To facilitate the machining of the racks 46 on the support 41, it is possible to attach to said support 41 a body 45 comprising the rolling track 48 cooperating with the roller 40, said body being fixed to said support 41 with at least one fixing screw 107.
L'étanchéité entre le support 41 et le bloc moteur 100 est assuré par un joint 47 logé dans une gorge 44 qui peut être ménagée soit dans le support 41 soit dans le bloc moteur 100.The seal between the support 41 and the engine block 100 is ensured by a seal 47 housed in a groove 44 which can be provided either in the support 41 or in the engine block 100.
La distance entre le bloc moteur 100 et le support 41 est réglée par une cale d'épaisseur 106, formant des moyens de réglage du positionnement du dispositif de transmission 1 , ladite cale 106 étant intercalée entre la face interne de la plaque 42 et la face externe du bloc moteur 100.The distance between the engine block 100 and the support 41 is adjusted by a thickness shim 106, forming means for adjusting the positioning of the transmission device 1, said shim 106 being interposed between the internal face of the plate 42 and the face external of the engine block 100.
La cale d'épaisseur 106 permet de régler la crémaillère de commande 7 en position verticale, tenant compte de l'empilement des côtes de l'ensemble des pièces comprises entre le plan d'appui du support 41 sur le bloc moteur 100 et le centre du cylindre de vérin 112 du vérin de commande 8.The thickness shim 106 makes it possible to adjust the control rack 7 in a vertical position, taking into account the stacking of the ribs of all the parts included between the support plane of the support 41 on the engine block 100 and the center of cylinder cylinder 112 of control cylinder 8.
L'épaisseur de la cale 106 est déterminée après mesure de l'empilement des côtes de l'ensemble des pièces comprises entre le plan d'appui du support 41 sur le bloc moteur 100 et le centre du cylindre de vérin 112 du vérin de commande 8.The thickness of the shim 106 is determined after measuring the stacking of the ribs of all the parts included between the support plane of the support 41 on the engine block 100 and the center of the jack cylinder 112 of the control jack 8.
En figures 4 et 5, on a illustré le vérin de commande 8 du dispositif de contrôle 12 qui est constitué d'une tige de vérin supérieure 10 présentant une partie filetée 11 vissée dans la tige de vérin inférieure 16 de la crémaillère de commande 7 et d'un piston de vérin 13 traversé en son milieu, au moyen d'un alésage 17, par la tige de vérin supérieure 10.In FIGS. 4 and 5, the control cylinder 8 of the control device 12 is illustrated, which consists of an upper cylinder rod 10 having a threaded part 11 screwed into the lower cylinder rod 16 of the control rack 7 and of a jack piston 13 traversed in the middle, by means of a bore 17, by the upper jack rod 10.
La tige de vérin supérieure 10 comporte une partie cylindrique 14 coopérant avec un alésage 114 ménagé dans la culasse de vérin 113 assurant au vérin de commande 8 un rapport entre volume déplacé et course de piston de vérin 13 qui est identique pour les chambres supérieure 121 et inférieure 122.The upper cylinder rod 10 comprises a cylindrical part 14 cooperating with a bore 114 formed in the cylinder head 113 ensuring that the control cylinder 8 has a ratio between displaced volume and cylinder piston stroke 13 which is identical for the upper chambers 121 and lower 122.
La tige de vérin supérieure 10 comporte une prise d'outil 15 permettant son serrage. La tige de vérin supérieure 10 comporte des moyens de centrage 135 qui permettent de centrer d'une part la tige de vérin supérieure 10 sur le piston de vérin 13 et d'autre part la tige de vérin inférieure 16 sur le piston de vérin 13.The upper jack rod 10 has a tool grip 15 allowing it to be clamped. The upper actuator rod 10 comprises centering means 135 which make it possible to center on the one hand the upper actuator rod 10 on the actuator piston 13 and on the other hand the lower actuator rod 16 on the actuator piston 13.
Selon une variante non représentée, la tige de vérin inférieure 16 peut présenter une partie filetée vissée dans la tige de vérin supérieure 10, et des moyens de centrage qui permettent de centrer d'une part la tige de vérin supérieure 10 sur le piston de vérin 13 et d'autre part la tige de vérin inférieure 16 su r le piston de vérin 13.According to a variant not shown, the lower actuator rod 16 may have a threaded part screwed into the upper actuator rod 10, and centering means which allow the upper actuator rod 10 to be centered on the actuator piston on the one hand 13 and on the other hand the lower jack rod 16 on the jack piston 13.
L'étanchéité entre la tige de vérin supérieure 10 et l'alésage 11 -4 de la culasse de vérin 113 est assuré par un joint 115. L'étanchéité entre la tige de vérin inférieure 16 et un alésage 11 6 ménagé dans le fond 117 du cylindre de vérin 112 est assuré par un joint 118.The seal between the upper cylinder rod 10 and the bore 11 -4 of the cylinder head 113 is provided by a seal 115. The seal between the lower cylinder rod 16 and a bore 11 6 formed in the bottom 117 cylinder cylinder 112 is provided by a seal 118.
Les joints 115 et 118 sont prévus pour pouvoir assurer une étanchéité tout en s'accommodant du jeu important prévu entre les tiges de vérin supérieure 10 et inférieure 16 et leurs alésages respectifs 114, 116.The seals 115 and 118 are provided in order to be able to provide a seal while accommodating the large clearance provided between the upper 10 and lower 16 cylinder rods and their respective bores 114, 116.
Cet agencement permet à la crémaillère de commande 7 de s'orienter dans le bloc moteur 100 afin que les dents 74 de la dite crémaillère s'alignent avec celles 52 de la roue dentée 5.This arrangement allows the control rack 7 to orient itself in the engine block 100 so that the teeth 74 of said rack align with those 52 of the toothed wheel 5.
Chaque joint 115 et 118 est composé, par exemple, d'un anneau externe 119 en matière plastique résistant au frottement et d'un joint torique interne 120 qui assure l'étanchéité entre l'anneau 119 et l'alésage 114, 116 correspondant. Le piston de vérin 13 est traversé verticalement par un autre alésage 18, présentant ou non au moins un lamage 19 permettant de limiter l'encombrement de l'ensemble du dispositif de contrôle 12, pour le passage d'u ne tige de contrôle 20 coopérant de part et d'autre de l'épaisseur du piston 13 avec des valves 21 et des ressorts 22.Each seal 115 and 118 is composed, for example, of an external ring 119 made of friction-resistant plastic and of an internal O-ring 120 which seals between the ring 119 and the corresponding bore 114, 116. The cylinder piston 13 is traversed vertically by another bore 18, with or without at least one counterbore 19 making it possible to limit the size of the whole of the control device 12, for the passage of a cooperating control rod 20 on either side of the thickness of the piston 13 with valves 21 and springs 22.
Chaque valve 21 est traversée par la tige de contrôle 20 et vient prendre appui directement sur la face supérieure ou inférieure correspondante du piston de vérin 13 ou du lamage 19. Chaque ressort 22 est traversé par la tige de contrôle 20 et vient prendre appui d'une part sur la valve 21 correspondante et d'autre part sur une butée 130 aménagée sur la tige de contrôle 20 et constituée, par exe ple, d'un anneau élastique 131 et d'une rondelle 132. Chaque valve 21 comporte un joint qui est composé, par exemple, d'un anneau en matière plastique 23 résistant au frottement et d'un joint torique interne 24 qui assure l'étanchéité entre l'anneau 23 et le corps de la valve 21. Les valves 21 peuvent être prévues en deux parties pour faciliter le montage du joint qu'elles comportent.Each valve 21 is crossed by the control rod 20 and comes to bear directly on the corresponding upper or lower face of the cylinder piston 13 or the counterbore 19. Each spring 22 is crossed by the control rod 20 and comes to bear on on the one hand on the corresponding valve 21 and on the other hand on a stop 130 arranged on the control rod 20 and constituted, for example, of an elastic ring 131 and a washer 132. Each valve 21 has a seal which is made up, for example, of a friction-resistant plastic ring 23 and an internal O-ring 24 which seals between the ring 23 and the body of the valve 21. The valves 21 can be provided in two parts to facilitate the mounting of the seal which they comprise.
Le jeu entre les valves 21 et la tige de contrôle 20 est suffisant pour permettre au piston de vérin 13 de pivoter légèrement dans le cylindre de vérin 112 afin que la crémaillère de commande 7 puisse s'orienter dans le bloc moteur 100 pour que les dents 74 de la dite crémaillère s'alignent avec celles 52 de la roue dentée 5, tout en permettant aux dites valves d'assurer l'étanchéité entre les chambres supérieure 121 et inférieure 122 du cylindre de vérin 112.The clearance between the valves 21 and the control rod 20 is sufficient to allow the piston of cylinder 13 to pivot slightly in the cylinder of cylinder 112 so that the control rack 7 can be oriented in the engine block 100 so that the teeth 74 of the said rack align with those 52 of the toothed wheel 5, while allowing the said valves to seal between the upper 121 and lower 122 chambers of the jack cylinder 112.
Les valves 21 peuvent donc légèrement pivoter par rapport à la tige de contrôle 20 afin qu'elles restent toujours en contact sur toute leur circonférence avec le piston de vérin 13. Chaque valve 21 peut présenter une faible surface de contact avec le piston de vérin 13, matérialisée par une arête circulaire périphérique 25 prévue pour augmenter la pression de contact exercée par lesdites valves 21 sur ledit piston de vérin 13. Cet agencement permet d'une part d'assurer une meilleure étanchéité et d'autre part aux valves 21 d'offrir une surface exposée à la pression du fluide côté piston de vérin 13 plus importante afin de faciliter le pilotage du dispositif de contrôle 12.The valves 21 can therefore pivot slightly relative to the control rod 20 so that they always remain in contact over their entire circumference with the cylinder piston 13. Each valve 21 can have a small contact surface with the cylinder piston 13 , materialized by a peripheral circular edge 25 intended to increase the contact pressure exerted by said valves 21 on said cylinder piston 13. This arrangement makes it possible on the one hand to ensure better sealing and on the other hand to the valves 21 of provide a surface exposed to the pressure of the fluid on the piston piston side 13 greater in order to facilitate the piloting of the control device 12.
La tige de contrôle 20 comporte, pour son guidage, une partie cylindrique 123 coopérant avec un alésage 124 ménagé dans la culasse de vérin 113. La tige de contrôle 20 comporte dans le prolongement de sa partie cylindrique 123 une extrémité filetée 125 permettant sa fixation à un dispositif de pilotage non représenté. L'étanchéité entre la tige de contrôle 20 et l'alésage 124 de la culasse de vérin 113 est assurée par un joint 126.The control rod 20 comprises, for its guidance, a cylindrical part 123 cooperating with a bore 124 formed in the cylinder head 113. The control rod 20 comprises, as an extension of its cylindrical part 123, a threaded end 125 allowing it to be fixed to a control device not shown. The seal between the control rod 20 and the bore 124 of the cylinder head 113 is ensured by a seal 126.
L'alésage 124 peut comporter un lamage 133 dans lequel peuvent évoluer le ressort 22 et la butée 130 se trouvant dans la chambre supérieure de vérin 121 , afin de limiter l'encombrement vertical du dispositif de contrôle 12.The bore 124 may include a countersink 133 in which the spring 22 and the stop 130 located in the upper chamber of the jack 121 can move, in order to limit the vertical size of the control device 12.
A l'opposé de la culasse de vérin 113 la tige de contrôle 20 est guidée dans un alésage 127 ménagé dans le fond 117 du cylindre de vérin 11 2. L'étanchéité entre la tige de contrôle 20 et l'alésage 127 du cylindre de vérin 112 est assurée par un joint 128.Opposite the cylinder head 113, the control rod 20 is guided in a bore 127 formed in the bottom 117 of the cylinder 11 cylinder 2. The seal between the control rod 20 and the bore 127 of the cylinder cylinder 112 is provided by a seal 128.
L'alésage 127 peut comporter un lamage 134 dans lequel peuvent évoluer le ressort 22 et la butée 130 se trouvant dans la chambre inférieure de vérin 122, afin de limiter l'encombrement vertical du dispositif de contrôle 12.The bore 127 may include a countersink 134 in which the spring 22 and the stop 130 located in the lower chamber of the jack 122 can move, in order to limit the vertical size of the control device 12.
La partie du piston de vérin 13 en contact avec le cylindre de vérin 112 présente un profil sphérique 26 formant une liaison de type rotule entre ledit piston de vérin 13 et ledit cylindre de vérin 112. Cet agencement est prévu pour permettre à la crémaillère de commande 7 de pivoter afin que ses dentures 74 puissent s'aligner avec les dentures 52 de la roue dentée 5.The part of the jack piston 13 in contact with the jack cylinder 112 has a spherical profile 26 forming a ball-type connection between said jack piston 13 and said jack cylinder 112. This arrangement is provided to allow the control rack 7 to pivot so that its teeth 74 can align with the teeth 52 of the toothed wheel 5.
Le piston de vérin 13 comporte de part et d'autre de son profil sphérique 26 des joints d'étanchéité 27.The piston of the jack 13 has on each side of its spherical profile 26 seals 27.
Les joints 27 sont prévus pour assurer l'étanchéité entre les chambres supérieure 121 et inférieure 122 du vérin de commande 8, malgré les jeux importants nécessaires à l'orientation du piston de vérin 13 dans le cylindre de vérin 112.The seals 27 are provided to seal between the upper 121 and lower 122 chambers of the control jack 8, despite the large clearances necessary for the orientation of the jack piston 13 in the jack cylinder 112.
Dans une variante, non représenté, les joints 27 sont composés, par exemple, d'un anneau externe en matière plastique résistant au frottement et d'un joint torique interne qui assure l'étanchéité entre l'anneau et le piston de vérin 13.In a variant, not shown, the seals 27 are composed, for example, of an external ring of friction-resistant plastic and of an internal O-ring which seals between the ring and the piston of the jack 13.
Ainsi, le profil sphérique 26 du piston de vérin 13 forme des premiers moyens donnant les libertés angulaires nécessaires au fonctionnement du dispositif de transmission 1.Thus, the spherical profile 26 of the cylinder piston 13 forms first means giving the angular freedoms necessary for the operation of the transmission device 1.
Le piston de vérin 13 peut comporter un clapet de décharge 137 qui pourra être constitué, par exemple, d'une bille 138 maintenue sur un siège ménagé dans le piston de vérin 13 par un ressort 139 (figure 10). Le clapet de décharge 137 permet de limiter la pression maximale de la cham re supérieure 121 du vérin de commande 8, et de ce fait, permet de limiter l'effort maximal exercé sur les dents 34, 51, 52, 74 du dispositif de transmission 1.The cylinder piston 13 may include a relief valve 137 which may consist, for example, of a ball 138 held on a seat formed in the cylinder piston 13 by a spring 139 (Figure 10). The discharge valve 137 makes it possible to limit the maximum pressure of the upper chamber 121 of the control cylinder 8, and therefore makes it possible to limit the maximum force exerted on the teeth 34, 51, 52, 74 of the transmission device 1.
La crémaillère de commande 7 comporte à l'opposé de sa denture 74, une face d'appui 75 venant coopérer avec une face d'appui 103 ménagée dans le bloc moteur 100 et dont la distance par rapport audit bloc moteur 100 est réglable, ceci constituant des moyens de réglage des jeux fonctionnels du dispositif de transmission 1.The control rack 7 comprises, opposite its toothing 74, a bearing face 75 coming to cooperate with a bearing face 103 formed in the engine block 100 and the distance from which relative to said engine block 100 is adjustable, this constituting means for adjusting the functional clearances of the transmission device 1.
La face d'appui 75 comprend une cavité 28 en portion de sphère présentant ou non en son pôle un logement cylindrique 29 pour un ressort 30 qui peut être, par exemple, de type hélicoïdal ou « belleville ».The bearing face 75 comprises a cavity 28 in the portion of a sphere having or not having in its pole a cylindrical housing 29 for a spring 30 which may be, for example, of helical or "belleville" type.
Le ressort 30 a pour fonction de maintenir en contact les différents organes du dispositif de transmission 1, lorsqu'un effort faible est exercé sur les dents 51, €>2 de la roue dentée 5. La cavité 28 est prévue pour recevoir la calotte 31 en portion de sphère d'u ne pièce d'appui 76 logée dans ladite cavité réalisant une liaison rotule entre la crémaillère de commande 7 et le bloc moteur 100 (figure 5). La calotte en portion de sphère 31 de la pièce d'appui 76 peut présenter en son pôle un logement cylindrique 36 pour le ressort 30.The function of the spring 30 is to keep the various members of the transmission device 1 in contact, when a weak force is exerted on the teeth 51, €> 2 of the toothed wheel 5. The cavity 28 is provided for receiving the cap 31 in a sphere portion of a support piece 76 housed in said cavity providing a ball joint between the control rack 7 and the engine block 100 (FIG. 5). The cap in the portion of a sphere 31 of the support piece 76 may have at its pole a cylindrical housing 36 for the spring 30.
La pièce d'appui 76 comporte à l'opposé de sa calotte en portion de sphère 31 une face plane 32 coopérant avec une autre face plane 103 ménagée dans le bloc moteur 100.The support piece 76 comprises, opposite its cap in the portion of a sphere 31, a flat face 32 cooperating with another flat face 103 formed in the engine block 100.
Cet agencement permettant à la crémaillère de commande 7 de se déplacer par rapport au bloc moteur 100.This arrangement allowing the control rack 7 to move relative to the engine block 100.
La pièce d'appui 76 peut comporter un réseau de canaux 33 permettant d'amener l'huile de lubrification d'une part sur sa face plane 32 et d'autre par sur sa calotte en portion de sphère 31. Ainsi, la liaison de type rotule entre la crémaillère de commande 7 et le bloc moteur 100 formée par le profil sphérique de la cavité 28 de ladite crémaillère de commande 7 et par la calotte en portion de sphère 31 de la pièce d'appui 76 constitue des seconds moyens donnant les libertés angulaires nécessaires au fonctionnement du dispositif de transmission 1.The support piece 76 may comprise a network of channels 33 making it possible to bring the lubricating oil on the one hand on its flat face 32 and on the other hand on its cap in the portion of a sphere 31. Thus, the connection of type ball joint between the control rack 7 and the engine block 100 formed by the spherical profile of the cavity 28 of said control rack 7 and by the cap in sphere portion 31 of the support piece 76 constitutes second means giving the angular freedoms necessary for the operation of the transmission device 1.
La face plane 103 du bloc moteur 100 est réalisée, par exemple, sur un support cylindrique 102 vissé dans ledit bloc.The planar face 103 of the engine block 100 is produced, for example, on a cylindrical support 102 screwed into said block.
Le support cylindrique 102 présente un filetage 108 réalisé sur son pourtour pour être vissé directement dans un orifice fileté 101 aménagé dans le bloc moteur 100.The cylindrical support 102 has a thread 108 made on its periphery to be screwed directly into a threaded orifice 101 arranged in the engine block 100.
Le support cylindrique 102 comporte une prise d'outil 109 permettant son serrage et son maintien en position lors de son blocage par l'intermédiaire d'un contre écrou 129.The cylindrical support 102 comprises a tool socket 109 allowing it to be clamped and held in position when it is blocked by means of a lock nut 129.
Le contre écrou 129 comporte une prise d'outil 111 permettant son serrage. La prise d'outil 111 est prévue de telle sorte que l'on puisse serrer le contre écrou 129 tout en maintenant le support cylindrique 102 au moyen de sa prise d'outil 109.The lock nut 129 has a tool socket 111 allowing it to be tightened. The tool socket 111 is provided so that the lock nut 129 can be tightened while maintaining the cylindrical support 102 by means of its tool socket 109.
Ainsi, le support cylindrique 102 et son contre écrou 129 vissés dans l'orifice fileté 101 du bloc moteur 100 constituent un dispositif de réglage des jeux fonctionnels du dispositif de transmission 1 dans le bloc moteur 100.Thus, the cylindrical support 102 and its lock nut 129 screwed into the threaded orifice 101 of the engine block 100 constitute a device for adjusting the functional clearances of the transmission device 1 in the engine block 100.
En variante, le support cylindrique 102 peut être rendu solidaire d'une plaque de forte épaisseur, non représentée, fixée par l'extérieur au bloc moteur 100 par l'intermédiaire de vis. Pour cette variante, le réglage des jeux fonctionnels du dispositif de transmission 1 dans le bloc moteur 100 est réalisé au moyen d'une cale d'épaisseur, non représentée. Cette cale d'épaisseur, disposée entre la plaque de forte épaisseur et le bloc moteur 100, permet de régler la distance entre la dite plaque et ledit bloc moteur.As a variant, the cylindrical support 102 can be made integral with a very thick plate, not shown, fixed from the outside to the engine block 100 by means of screws. For this variant, the adjustment of the functional clearances of the transmission device 1 in the engine block 100 is carried out by means of a shim, not shown. This thickness spacer, disposed between the very thick plate and the engine block 100, makes it possible to adjust the distance between said plate and said engine block.
Selon une variante, non représentée, la cavité 28 en portion de sphère, servant de logement à la calotte 31 en portion de sphère de la pièce d'appui 76, peut être aménagée dans le support cylindrique 102.According to a variant, not shown, the cavity 28 in the portion of a sphere, serving as a housing for the cap 31 in the portion of the sphere of the support piece 76, can be arranged in the cylindrical support 102.
Dans cette variante, la face plane 32 de la pièce d'appui 76 vient glisser sur une face plane aménagée sur la crémaillère de commande 7, c'est à dire, à l'inverse de celle décrite précédemment, sans pour cela changer l'objet de la présente invention.In this variant, the flat face 32 of the support piece 76 slides on a flat face fitted on the control rack 7, that is to say, unlike that described above, without changing the object of the present invention.
En figures 7 à 10 on a montré une variante de réalisation des seconds moyens donnant les libertés angulaires nécessaires au fonctionnement du dispositif de transmission 1 prévu au niveau de la crémaillère de commande 7 et plus particulièrement de sa liaison de type rotule prenant appui sur le bloc moteur 100.In FIGS. 7 to 10, an alternative embodiment of the second means has been shown, giving the angular freedoms necessary for the operation of the transmission device 1 provided at the level of the control rack 7 and more particularly of its ball-type connection bearing on the block. motor 100.
Dans cette variante, les seconds moyens sont constitués d'un vérin presseur 62 dont le piston 61 réalise grâce à un profil sphérique une liaison de type rotule entre la crémaillère de commande 7 et le bloc moteur 100.In this variant, the second means consist of a pressing cylinder 62, the piston 61 of which makes a ball-type connection between the control rack 7 and the engine block 100 thanks to a spherical profile.
Un distributeur 65 permet de réaliser une comparaison permanente des pressions régnant dans les chambres supérieure 121 et inférieure 122 afin de relier celle ayant la pression la plus élevée avec la chambre 66 du vérin presseur 62.A distributor 65 makes it possible to carry out a permanent comparison of the pressures prevailing in the upper 121 and lower 122 chambers in order to connect the one having the highest pressure with the chamber 66 of the pressure cylinder 62.
Ainsi, le distributeur 65 permet de mettre en relation la chambre supérieure 121 ou inférieure 122 dont la pression est la plus élevée avec la chambre 66 du vérin presseur 62. Le vérin presseur 62 comporte un ressort 63 qui permet de maintenir en contact les différents organes du dispositif de transmission 1 , lorsque la pression régnant dans la chambre 66 est faible.Thus, the distributor 65 makes it possible to connect the upper chamber 121 or lower 122 whose pressure is the highest with the chamber 66 of the press cylinder 62. The press cylinder 62 comprises a spring 63 which makes it possible to keep the various members in contact of the transmission device 1, when the pressure prevailing in the chamber 66 is low.
Le ressort 63 peut être de type hélicoïdal ou « belleville ».The spring 63 can be of helical or “belleville” type.
A titre d'exemple, le distributeur 65 peut être logé dans l'épaisseur du piston de vérin 13. Dans ce cas, il est relié au vérin presseur 62 par des canaux 64 aménagés dans le piston de vérin 13, les tiges de vérin supérieure 10 et inférieure 16 et dans la crémaillère de commande 7.By way of example, the distributor 65 can be housed in the thickness of the cylinder piston 13. In this case, it is connected to the pressing cylinder 62 by channels 64 arranged in the cylinder piston 13, the upper cylinder rods 10 and lower 16 and in the control rack 7.
On note que le bloc moteur 100 peut être réalisé en acier, en fonte ou en alliage léger. Il peut comprendre une ou plusieurs chemises sèches ou humides. Il peut également comporter un ou plusieurs cylindres 110 directement alésés dans ledit bloc moteur 100.Note that the engine block 100 can be made of steel, cast iron or light alloy. It can include one or more dry or wet shirts. It may also include one or more cylinders 110 directly bored in said engine block 100.
Le bloc moteur 100 peut comporter au moins un canal et/ou au moins une chambre dans lesquels circule un fluide qui assure le refroidissement du moteur. Le bloc moteur 100 peut comporter au moins un canal et/ou au moins une chambre dans lesquels circule un fluide de lubrification des différents composants du moteur. On remarque que le bloc moteur 100 comporte des chapeaux de palier 141 fixés par au moins deux vis, lesdits chapeaux de paliers 141 pouvant être incorporés dans un carter-paliers 140.The engine block 100 may comprise at least one channel and / or at least one chamber in which a fluid circulates which ensures the cooling of the engine. The engine block 100 can comprise at least one channel and / or at least one chamber in which a lubricating fluid of the various engine components circulates. It will be noted that the engine block 100 includes bearing caps 141 fixed by at least two screws, said bearing caps 141 possibly being incorporated in a bearing housing 140.
On constate que le bloc moteur 100 peut comporter des arbres d'équilibrage pour limiter l'effet des vibrations, lesdits arbres d'équilibrage pouvant être montés dans un carter indépendant fixé au bloc moteur 100. Le bloc moteur 100 peut comporter un carter de lubrifiant réalisé soit en tôle emboutie, soit en alliage léger ou en matière plastique, comprenant ou non des structures de renforcement. II doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tout autre équivalent. It is noted that the engine block 100 may include balancing shafts to limit the effect of vibrations, said balancing shafts being able to be mounted in an independent casing fixed to the engine block 100. The engine block 100 may comprise a lubricant casing made either from stamped sheet metal, light alloy or plastic, with or without reinforcing structures. It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by any other equivalent.
