Abstract: front page image
(EN) The invention relates mainly to a starter having a maximum torque Cmax in N.m comprising: a pinion belonging to a starter drive assembly mounted on a drive shaft, said starter drive assembly being movable between an inoperative position and an operative position; a front bearing assembled between a mounting and said drive shaft in order to guide the rotation of said drive shaft, a starter drive assembly; an overrunning clutch (73) comprising: a driven ring (76) comprising on the outer periphery thereof an inner track (77) with a radius R measured in mm, and a driving ring (78) comprising ramps (79) on the inner periphery thereof; and N rollers (82) each mounted between said inner track (77) and a corresponding ramp (79), each roller (82) comprising a pin (Y) having an axial length L measured in mm and a radius r measured in mm, characterised in that said overrunning clutch (73) has dimensions that comply with the following relation: ε =((Cmax/(1000N 5 /2*L*0.05))*((R+r)/(R*r))5 /2)√2 and in that ε is between 300 and 700.
(FR) L'invention porte principalement sur un démarreur ayant un couple maximum Cmax en N.m comprenant: -un pignon appartenant à un lanceur monté sur un arbre d'entraînement, ledit lanceur étant mobile entre une position repos et une position active, -un palier avant monté entre un support et ledit arbre d'entraînement pour guider en rotation ledit arbre d'entraînement, un lanceur, -une roue libre (73) comprenant: -une bague entraînée (76) comprenant sur sa périphérie externe une piste interne (77) de rayon R mesuré en mm, et -une bague entraînante (78) comprenant des rampes (79) sur sa périphérie interne, -N rouleaux (82) montés chacun entre ladite piste interne (77) et une rampe (79) correspondante, chaque rouleau (82) comprenant un axe (Y) ayant une longueur axiale L mesurée en mm et un rayon r mesuré en mm, caractérisé en ce que ladite roue libre (73) a des dimensions telles qu'elle respecte la relation suivante: ε =((Cmax/(1000N 5/2*L*0.05))*((R+r)/(R*r))5/2)√2 et en ce que εest compris entre 300et 700.
