Problems solved by technology

However, such a system requires the development of complex tooling to be able to manufacture the pinion body by cold forging
In addition, the pinion body is mechanically weakened due to the grooves being made along its entire length

Abstract

The invention mainly relates to a starter (11) for a combustion engine of a motor vehicle, comprising: an electric motor (15); a drive pinion (60); a pinion body (61), on which the drive pinion (60) is mounted on: transmission shaft (12), able to transmit the torque from said electric motor (15) to said transmission pinion (60) via said pinion body, said pinion body (61) being mounted with opposite Ability to slide axially on said transmission shaft (12), and wherein there is a chamber (86) which is in particular composed of one end of said transmission shaft (12) and said pinion body (61 ) is bounded by an end opposite to the end of the transmission shaft (12), the chamber (86) is formed via an annular wall made in the pinion body (61) or the transmission shaft (12) Formed through hole (85) ventilation.

Description

technical field [0001] The invention relates to a starter for a combustion engine of a motor vehicle, equipped with air ventilation holes. The invention finds particularly advantageous application in (but not exclusively) automatic combustion engine stop and start systems for vehicles. Background technique [0002] For starting a combustion engine, in particular a combustion engine of a motor vehicle, it is known practice to use a starter provided with a starter drive assembly capable of transferring rotational energy from the starter to the starter ring gear of the combustion engine . The starter drive assembly is mounted with the ability to slide on a drive shaft that is coupled to the shaft of the electric motor via a reduction gearing. [0003] The starter drive assembly is moveable between an active position in which a drive pinion meshes with the starter ring gear to start it following energization of the ignition, and a rest position , in the rest position, the dri...
