Title (EN) CONNECTING ROD AND PISTON ASSEMBLY WITH GUIDE PIN GUIDING THE ROTATION OF THE PISTON
(FR) ENSEMBLE BIELLE ET PISTON AVEC AXE DE GUIDAGE EN ROTATION DU PISTON
Abstract:
(EN) The invention relates to an assembly of connecting rod (1) and piston (2) comprising a substantially cylindrical skirt (3) surrounding, via a curved face (3a), an end portion of the connecting rod (1) for an internal combustion engine, the piston (2) having a central axis (A) and being articulated to the connecting rod (1) by a ball joint connection between a spherical surface of the piston (2) and a spherical surface borne by the end portion of the connecting rod (1). The connecting rod (1) bears a guide pin (6) perpendicular to the central axis (A) of the piston (2) and secured to the end portion of the connecting rod (1), the curved face (3a) of the skirt (3) comprising two grooves (7) opening to the outside of the skirt (3) and diametrically opposite each other respectively accepting one end of the guide pin (6) for angular pivoting of the piston (2) about its central axis (A).
(FR) L'invention concerne un ensemble bielle (1) et piston (2) comportant une jupe (3) sensiblement cylindrique entourant par une face courbe (3a) une portion d'extrémité de la bielle (1) pour un moteur à combustion interne, le piston (2) présentant un axe central (A) et étant articulé sur la bielle (1) par une liaison rotule entre une surface sphérique du piston (2) et une surface sphérique portée par la portion d'extrémité de la bielle (1). La bielle (1) porte un axe de guidage (6) perpendiculaire à l'axe central (A) du piston (2) et solidaire de la portion d'extrémité de la bielle (1), la face courbe (3a) de la jupe (3) comportant deux gorges (7) débouchantes à l'extérieur de la jupe (3) et diamétralement opposées recevant respectivement une extrémité de l'axe de guidage (6) pour un pivotement angulaire du piston (2) autour de son axe central (A).
