Title
(EN) CONNECTING ROD FOR AN INTERNAL COMBUSTION ENGINE WITH ADJUSTABLE COMPRESSION RATIO
(FR) BIELLE POUR MOTEUR À COMBUSTION INTERNE À TAUX DE COMPRESSION RÉGLABLE
Abstract
(EN)
The present invention refers to a connecting rod (1) for an internal combustion engine with an adjustable compression ratio comprising a crank pin bearing eye (2) for connecting the connecting rod (1) to a crank shaft of the internal combustion engine, a connecting rod bearing eye (3) for connecting said connecting rod (1) to a cylinder piston of said internal combustion engine and an eccentrical element adjustment device (4) for adjusting the distance between said crank pin bearing eye (2) and said connecting rod bearing eye (3), wherein said eccentrical element adjustment device (4) comprises an eccentrical element (5) including said connecting rod bearing eye (3), an eccentrical element lever (6) and eccentrical element rods (8) engaging the eccentrical element lever (6), wherein said eccentrical element rods (8) are loaded with a force generated by hydraulic pressure in hydraulic cavities (9), wherein an outer surface (11) of the eccentric element (5) and/or an inner surface (12) at the border of the connecting rod bearing eye (3) is provided with a texture (10).
(FR)
La présente invention concerne une bielle (1) pour un moteur à combustion interne ayant un taux de compression réglable comprenant un œil de roulement à aiguilles de manivelle (2) pour relier la bielle (1) à un vilebrequin du moteur à combustion interne, un œil de palier de bielle (3) pour relier ladite bielle (1) à un piston de cylindre dudit moteur à combustion interne et un dispositif de réglage d'élément excentrique (4) pour régler la distance entre ledit œil de roulement à aiguilles de manivelle (2) et ledit œil de palier de bielle (3), où ledit dispositif de réglage d'élément excentrique (4) comprend un élément excentrique (5) contenant ledit œil de palier de bielle (3), un levier d'élément excentrique (6) et des tiges d'élément excentrique (8) s'engageant avec le levier d'élément excentrique (6), où lesdites tiges d'élément excentrique (8) sont soumises à une force produite par une pression hydraulique dans des cavités hydrauliques (9), où une surface extérieure (11) de l'élément excentrique (5) et/ou une surface intérieure (12) au bord de l'œil de palier de bielle (3) comporte une texture (10).
