Starter for starting thermal engine of car, has axial thrust provided with protrusion for limiting stroke of driver in active advanced position, where axial thrust ensures guidance between driver and driver shaft in active advanced position

摘要

The starter (30) has a driver (33) axially movable on a driver shaft (32) between a retracted rest position and an active advanced position to enable engagement of a pinion (35) with a cogwheel of an engine of a car. The driver cooperates with the driver shaft via a helical bond formed by a toothing (56) having a shape complementary to grooves (57) on a portion of the driver shaft. An axial thrust (63) is provided with a protrusion to limit a stroke of the driver in the advanced position, where the axial thrust ensures guidance between the driver and the driver shaft in the advanced position.
