Title (EN) ISOLATING DECOUPLER
(FR) DÉCOUPLEUR ISOLANT
Abstract:
(EN) An isolating decoupler comprising a hub, a pulley journalled to the hub, a torsion spring having a first torsion spring end welded directly to the hub, a wrap spring having a first wrap spring end welded directly to a second torsion spring end, a wrap spring outer surface fictionally engaged with a pulley inner surface, and a wrap spring second end temporarily engagable with the torsion spring first end whereby the frictional engagement between the wrap spring outer surface and the pulley inner surface is progressively released as a torque load increases.
(FR) Un découpleur isolant comprenant un moyeu, une poulie tourillonnée sur le moyeu, un ressort de torsion ayant une première extrémité de ressort de torsion soudée directement au moyeu, un ressort enroulé ayant une première extrémité de ressort enroulé soudée directement à une seconde extrémité de ressort de torsion, une surface externe de ressort enroulé en prise par friction avec une surface interne de poulie, et une seconde extrémité de ressort enroulé pouvant venir temporairement en prise avec la première extrémité de ressort de torsion, ce par quoi l'engagement par friction entre la surface externe de ressort enroulé et la surface interne de poulie est progressivement libéré lorsqu'une charge de couple augmente.
