Abstract

La présente invention concerne une bielle. La bielle comporte un premier corps de bielle (20) attaché à un deuxième corps de bielle (30) par un organe (50) de réglage d’écartement fileté. Un frein (60) comporte un premier contre-écrou (61) vissé à un premier tronçon fileté (51) de l’organe (50) et un deuxième contre-écrou (62) vissé à un deuxième tronçon fileté (52) de l’organe (50). Le frein (60) comporte : au moins un fil frein central (71) coopérant avec le premier corps de bielle (20) ainsi qu’avec l’organe (50) de réglage d’écartement fileté et le deuxième corps de bielle (30), au moins un premier fil frein latéral (72) coopérant avec le premier corps de bielle (20) et le premier contre-écrou (61), et au moins un deuxième fil frein latéral (73) coopérant avec le deuxième corps de bielle (30) et le deuxième contre-écrou (62) Figure d’abrégé : figure 4
