LANCEUR A FRICTION POUR ENGRENEMENT AVEC UNE COURONNE DE DEMARRAGE D'UN MOTEUR THERMIQUE ET DEMARREUR D'UN MOTEUR THERMIQUE COMPORTANT UN TEL LANCEUR

摘要

A friction starter drive unit for a starter, comprising: a pinion including a hole for the passage of a drive shaft; a drive part including a hole for the passage of a drive shaft, said drive part being mounted such as to be rotationally fixed with the pinion; a drive element including a hole for the passage of a drive shaft of a starter, which element can move in translation along axis X of the hole in relation to the drive part between an uncoupled position and a coupled position; and a friction coupling means arranged to couple the drive element to the drive part when the drive element is in the coupled position. The starter drive unit comprises a return means that exerts a force on the drive element and a force on the drive part in the direction of the uncoupled position.
