Abstract

La présente invention concerne un disque entraîné par embrayage et un embrayage, le disque entraîné par embrayage comprenant deux plaques latérales, deux brides de moyeu entre les deux plaques latérales et une pluralité de ressorts d'amortissement principaux. Un premier ressort d'amortissement principal parmi la pluralité de ressorts d'amortissement principaux correspond uniquement à une première bride de moyeu et un second ressort d'amortissement principal correspond uniquement à une seconde bride de moyeu, de telle sorte que le premier ressort d'amortissement principal et le second ressort d'amortissement principal sont agencés en série pendant la transmission de couple du disque entraîné par embrayage. Par conséquent, l'angle de rotation relative total des deux brides de moyeu est égal à la somme de l'angle de rotation relative de la première bride de moyeu par rapport aux plaques latérales et de l'angle de rotation relative des plaques latérales par rapport à la seconde bride de moyeu. De cette manière, l'agencement en série des ressorts d'amortissement principaux du disque entraîné par embrayage peut obtenir une rigidité de torsion principale à deux niveaux, et l'angle de torsion des ressorts d'amortissement principaux du disque entraîné par embrayage est important, améliorant ainsi l'effet d'atténuation sur les vibrations de torsion, ce qui améliore l'effet d'amortissement.
