Motor vehicle starter comprises pinion, selector and conical coupling clutch with friction surfaces fixed to pinion and selector

摘要

The starter drive assembly comprises a pinion (1), a selector (2) and a conical coupling clutch. The clutch has a first conical friction surface (8) fixed to the pinion and a second conical friction surface (8') fixed to the selector. The engaging clutch comprises a recess which has a base elongated by an annular sleeve (1b) extending axially towards one of the pinion/selector elements and an elastic element (10) which presses axially on a first stop, fixed to the clutch, in order to engage a second stop (4'), fixed to one of the pinion/selector elements.
