Description
Domaine technique de l'inventionTechnical field of the invention
L’invention concerne un élément de moteur à combustion interne comprenant un moyen de diffusion d’huile. L’invention porte encore sur un moteur à combustion interne comprenant un tel élément. L’invention porte enfin sur un véhicule comprenant un tel moteur à combustion interne ou un tel élément de moteur.The invention relates to an internal combustion engine component comprising an oil diffusion means. The invention also relates to an internal combustion engine comprising such an element. The invention finally relates to a vehicle comprising such an internal combustion engine or such an engine element.
Etat de la technique antérieureState of the prior art
Un moteur à combustion interne comprend généralement un système de refroidissement liquide comprenant un circuit. Un tel système de refroidissement liquide comprend généralement une pompe à liquide de refroidissement qui fait circuler un liquide de refroidissement au sein du circuit. Une telle pompe à liquide de refroidissement est généralement entraînée en rotation par une courroie, généralement appelée « courroie d’accessoires », par l’intermédiaire d’une transmission reliée au vilebrequin du moteur.An internal combustion engine generally includes a liquid cooling system comprising a circuit. Such a liquid cooling system generally comprises a coolant pump which circulates a coolant within the circuit. Such a coolant pump is usually driven in rotation by a belt, generally called an "accessory belt", through a transmission connected to the engine crankshaft.
Dans certains cas il n’est pas possible d’implanter une courroie d’accessoires, notamment par manque de place, au sein d’un carter de distribution du moteur. C’est notamment le cas sur un moteur à combustion interne destiné à entraîner en rotation une machine électrique apte à recharger une batterie de traction et/ou de propulsion d’un véhicule électrique.In some cases it is not possible to install an accessories belt, in particular due to a lack of space, within an engine timing cover. This is particularly the case with an internal combustion engine intended to rotate an electric machine capable of recharging a traction and/or propulsion battery of an electric vehicle.
En effet, la transmission entre le moteur à combustion interne et la machine électrique contraint le carter de distribution. Il en résulte l’utilisation d’une transmission par chaîne pour entraîner la pompe à liquide de refroidissement.Indeed, the transmission between the internal combustion engine and the electric machine constrains the timing cover. This results in the use of a chain drive to drive the coolant pump.
Cependant une transmission par chaîne a besoin d’être lubrifiée pour être fiable et durable. Or il est complexe de lubrifier une transmission par chaîne à ce niveau du moteur à combustion interne.However, a chain transmission needs to be lubricated to be reliable and durable. However, it is complex to lubricate a chain transmission at this level of the internal combustion engine.
Présentation de l'inventionPresentation of the invention
Le but de l’invention est de fournir un élément de moteur remédiant aux inconvénients ci-dessus. En particulier, l’invention propose une solution simple, fiable et économique de lubrification d’une transmission par chaîne de pompe à liquide de refroidissement.The object of the invention is to provide an engine element remedying the above drawbacks. In particular, the invention proposes a simple, reliable and economical solution for lubricating a coolant pump chain transmission.
Pour atteindre cet objectif, l’invention porte sur un élément de moteur à combustion interne, notamment un carter cylindre, comprenant une rampe de canalisation d’huile sous pression destinée à lubrifier au moins une première pièce au sein de l’élément, l’élément comprenant un moyen de diffusion d’huile sous pression en dehors de l’élément de sorte à lubrifier au moins une deuxième pièce agencée en dehors de l’élément.To achieve this objective, the invention relates to an internal combustion engine element, in particular a cylinder block, comprising a ramp for channeling oil under pressure intended to lubricate at least a first part within the element, the element comprising a means of diffusing oil under pressure outside the element so as to lubricate at least one second part arranged outside the element.
Le moyen de diffusion peut comprendre un gicleur fixé à une extrémité de la rampe, notamment fixé par frettage dans l’élément.The diffusion means may comprise a nozzle fixed to one end of the ramp, in particular fixed by shrink fitting in the element.
Le gicleur peut comprendre un conduit primaire, notamment un conduit primaire axial, et un conduit secondaire, notamment un conduit secondaire radial, le conduit secondaire pouvant déboucher dans le conduit primaire.The nozzle may comprise a primary duct, in particular an axial primary duct, and a secondary duct, in particular a radial secondary duct, the secondary duct possibly opening into the primary duct.
Le conduit primaire et le conduit secondaire du gicleur peuvent être de section circulaire, le diamètre du conduit primaire pouvant être supérieur au diamètre du conduit secondaire, notamment le diamètre du conduit secondaire pouvant être compris entre 0.2 mm et 0.8 mm.The primary duct and the secondary duct of the nozzle may be of circular section, the diameter of the primary duct possibly being greater than the diameter of the secondary duct, in particular the diameter of the secondary duct possibly being between 0.2 mm and 0.8 mm.
Le moyen de diffusion et/ou l’élément peut comprendre un moyen de positionnement du moyen de diffusion par rapport à l’élément de sorte à orienter la diffusion d’huile.The diffusion means and/or the element can comprise a means for positioning the diffusion means relative to the element so as to direct the diffusion of oil.
Le moyen de positionnement peut comprendre :
- un moyen d’indexage mâle, notamment un méplat mâle, ménagé sur le moyen de diffusion ou sur l’élément, et
- un moyen d’indexage femelle, notamment un méplat femelle, ménagé sur l’élément ou sur le moyen de diffusion,
les moyens d’indexage mâle et femelle pouvant coopérer entre eux au cours de la fixation du moyen de diffusion sur l’élément.The positioning means may include:
- a male indexing means, in particular a male flat, provided on the diffusion means or on the element, and
- a female indexing means, in particular a female flat, formed on the element or on the diffusion means,
the male and female indexing means being able to cooperate with each other during the fixing of the diffusion means on the element.
L’invention porte encore sur un moteur à combustion interne, notamment destiné à entraîner un véhicule et/ou à entraîner en rotation un moyen de production d’énergie électrique d’un véhicule, notamment d’un véhicule automobile, notamment d’un véhicule électrique, comprenant un élément de moteur tel que défini précédemment.The invention also relates to an internal combustion engine, in particular intended to drive a vehicle and/or to drive in rotation a means of producing electrical energy of a vehicle, in particular of a motor vehicle, in particular of a vehicle electric, comprising a motor element as defined above.
Le moteur à combustion interne peut comprendre un carter, notamment un carter de distribution, et le moyen de diffusion peut traverser le carter, notamment avec un jeu entre le moyen de diffusion et le carter.The internal combustion engine may comprise a casing, in particular a timing casing, and the diffusion means may pass through the casing, in particular with a clearance between the diffusion means and the casing.
Le moteur à combustion interne peut comprendre une pompe à liquide de refroidissement et une transmission d’entraînement en rotation de la pompe à liquide de refroidissement, l’au moins une deuxième pièce pouvant comprendre un élément de la transmission.The internal combustion engine may include a coolant pump and a coolant pump rotary drive transmission, the at least one second part may include a component of the transmission.
L’invention porte encore sur un véhicule, notamment un véhicule automobile, comprenant un moteur à combustion interne tel que défini précédemment ou un élément de moteur tel que défini précédemment.The invention also relates to a vehicle, in particular a motor vehicle, comprising an internal combustion engine as defined above or an engine element as defined above.
