Title (EN) STARTER SOLENOID ASSEMBLY WITH PLUNGER DAMPING ARRANGEMENT
(FR) ENSEMBLE SOLÉNOÏDE DE DÉMARREUR AVEC AGENCEMENT AMORTISSEUR DE PLONGEUR
Abstract:
(EN) An electric starting system for cranking an internal combustion engine that has a starter solenoid assembly having plurality of "O" rings mounted on the tapered groove of the plunger assembly. The arrangement is such that, when the coils are energized the strong magnetic force attracts the plunger to the iron rod and rotates the pinion in axial direction to engage it with the engine ring gear by the elastic force of the mesh spring. Due to the high speed of the plunger and the mass of the drive assembly and pinion, the mesh spring collapses and closes the contact prior to the smooth engagement of the pinion with the ring gear, resulting in engagement problem. Thus the present invention ensures safe engagement of pinion and ring gear and also prevents the water/dust entry inside the plunger or contact assembly, eliminating the need of an additional shroud.
(FR) La présente invention concerne un système de démarrage électrique pour démarrer un moteur à combustion interne qui a un ensemble solénoïde de démarreur ayant une pluralité de joints toriques montés sur la rainure conique de l’ensemble plongeur. L’agencement est conçu de manière que, lorsque les bobines sont excitées, la force magnétique importante attire le plongeur vers la tige en fer et tourne le pignon dans une direction axiale pour le mettre en prise avec la couronne du moteur par la force élastique du ressort d’engrenage. En raison de la grande vitesse du plongeur et de la masse de l’ensemble d’entraînement et du pignon, le ressort d’engrenage se comprime et ferme le contact avant l’engagement progressif du pignon avec la couronne, engendrant un problème de prise. Ainsi, la présente invention assure une prise sûre du pignon et de la couronne et prévient également une entrée d’eau/de poussières à l’intérieur de l’ensemble plongeur ou contact, éliminant le besoin d’une coiffe supplémentaire.
