Title (EN) ELASTIC FIXING ELEMENT FOR A PISTON OF A VARIABLE COMPRESSION RATIO ENGINE
(FR) FIXATION ELASTIQUE POUR PISTON DE MOTEUR A TAUX DE COMPRESSION VARIABLE
Abstract: front page image
(EN)The invention relates to an elastic fixing element for a piston (2) of a variable compression ratio engine (10), said fixing element consisting of at least one metal rod (15) held under tension between the piston (2) and the transmission member (2) and applying a strong contact pressure between the base of the piston (2) and the upper face of the transmission member (3), said piston (2) being tightened according to a previously calculated angle enabling the metal rod (15) formed by a dowel (16) to be subjected to a desired tension strain and enabling the tightening pre-stress to be reached between the piston (2) and the transmission member (3), and indexed in rotation in relation to the transmission member (3) by an additional tightening which does not significantly increase the tightening pre-stress, said dowel (16) continuing to extend under the same tension strain by plastic deformation.
(FR)La fixation élastique pour piston (2) d'un moteur à taux de compression variable (10) suivant la présente invention est constituée d'au moins une tige métallique (15) maintenue en tension entre ledit piston (2) et ledit organe de transmission (3) et qui applique une forte pression de contact entre la base dudit piston (2) et la face supérieure dudit organe de transmission (3), ledit piston (2) étant d'une part serré selon un angle préalablement calculé permettant que la tige métallique (15) constitué d'un goujon (16) soit soumis à un effort de tension recherché et que la précontrainte de serrage soit atteinte entre ledit piston (2) et l'organe de transmission (3) et d'autre part indexé en rotation par rapport à l'organe de transmission (3), par un serrage additionnel qui n'augmente pas significativement la précontrainte de serrage, ledit goujon (16) continuant à s'allonger à même effort de tension par déformation plastique.
