Starter motor comprises a pinion engaging with a gear wheel, under the action of a ring forced towards the wheel by an elastic element surrounded by pressure and transmission elements

摘要

Gear comprises a free wheel (3) mounted on the motor shaft (1). The free wheel has a ring (3A), which can be displaced towards the gear wheel (50) so that the pinion (3P) engages with the gear wheel (50). The ring is pushed by an elastic element (6) surrounded by a pressure element (5a) and a transmission element (5b). The assembly is placed between the ring and the piston (4).
