STARTER FOR A COMBUSTION ENGINE

摘要

A starter motor (1) for a heat engine of a motor vehicle, comprising: an electric motor having a stator (7) and a rotor (3) mounted on a rotor shaft (5); a translatably mobile starter shaft (15) carrying a drive pinion (13) that can move from an idle position wherein the drive pinion (13) is released from a rotational element connected to the crankshaft of the heat engine to an active position wherein the drive pinion (13) is used to rotatably drive the rotational element connected to the crankshaft of the heat engine; and a speed reducer group (17) inserted between the rotor shaft (5) and the starter shaft (15).

1. Starter (1) for a thermal engine of a motor vehicle, comprising:
an electric motor with a stator (7) and a rotor (3) mounted on a rotor shaft (5); a launcher shaft (15) which is mobile in translation, and supports a drive unit (13) which can go from a position of rest in which the drive unit (13) is released from a rotary element connected to the crankshaft of the thermal engine, to an active position in which the drive unit (13) is designed to rotate the rotary element connected to the crankshaft of the thermal engine; a speed reducer assembly (17) which is interposed between the rotor shaft (5) and the launcher shaft (15),wherein it additionally comprises:
a free wheel (16) which is immobile in translation with an input end connected in rotation to the speed reducer assembly (17), and an output end formed by a drive shaft (18); the launcher shaft being (15) mounted such as to be mobile in translation on the drive shaft (18) by means of a helical connection.
