STARTER DRIVE FOR INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a starter drive (1) for an internal combustion engine having a starter ring gear comprising: a pinion (20) intended to mesh with the starter ring gear; a pinion body (31) rigidly connected in rotation to the pinion (20); a friction element (311) such as a friction disk encased on the body of the pinion (30) and capable of being tightened axially between a reaction plate (312) and a pressure plate (411); a driver (40) axially movably mounted relative to the pinion (20) between an inoperative position and an operative position on which at least one friction element (313), such as a friction disk capable of being axially tightened between the reaction plate (312) and the pressure plate (411), is mounted; and a cover (32) rigidly connected to the pinion body (30) that includes a first portion (3211), said cover (32) being in contact with the pinion body (30) and in contact with the driver (40) in the inoperative position and having a of friction coefficient of contact of the first portion (3211) of the cover on the driver (40) is no higher than 0.3.
