Abstract: The invention relates mainly to a starter (11) for a motor vehicle combustion engine, comprising: an electric motor (15), a drive pinion (60), a pinion body (61) on which said drive pinion (60) is mounted, a drive shaft (12) able to transmit a torque derived from the electric motor (15) to the drive pinion (60) via the pinion body, the pinion body (61) being mounted with the ability to slide axially with respect to the drive shaft (12), and in which, with there being a chamber (86) delimited notably by one end of the drive shaft (12) and one end of the pinion body (61) opposite the end of the drive shaft (12), the chamber (86) is vented via a through-opening (85) made in an annular wall of the drive shaft (12) or of the pinion body (61).

Abstract: Brush holder support plate (1) for an electric engine comprises a central through-hole (2) for the engine manifold and guide elements (10) for receiving brush holders (20) in sliding connection on the plate. The plate allows the brush holder to be mounted on the plate, engaging same in the direction running from the edge (1e) of the plate towards the central through-hole (2). The plate comprises a non-return stop (11) for each brush holder (20) after the latter has been mounted in sliding connection on the plate, the stop being elastically retractable. The brush holders (20) have a base shaped so as to be received in sliding connection in the guide elements (10) of the plate (1). They have a recess in the base of same suitable for being engaged by the corresponding non-return stop (11) of the plate (1).

Abstract: The invention relates mainly to a starter for a heat engine of a motor vehicle comprising: at least one electromagnetic contactor comprising a positive output terminal, at least one electric motor, the electric motor comprising: at least one brush cage (43), at least one positive brush (35) mounted in the brush cage (43), an electrical path (91) between the positive brush (35) and the positive output terminal (32), and at least one thermal protection (96) situated in the electrical path (91), in which the thermal protection is suitable for disconnecting the two elements (93, 95) when the thermal protection has a temperature above a temperature threshold to electrically disconnect the positive output terminal relative to the positive brush (35).

Abstract: A starter for a motor vehicle comprises an electric motor having an output shaft which drives a coaxial starter head through a speed reducer. The speed reducer incorporates an epicyclic gear train, including a cylindrical casing within which the internally toothed crown wheel of the epicyclic gear train is mounted in rotation. The crown wheel is coupled in rotation to the casing through a friction type torque limiting device, which is interposed axially between the crown wheel and a transverse plate of the casing. The torque limiting device includes at least one annular transverse friction surface of the crown wheel, which is biased elastically into axial engagement against a reaction surface coupled in rotation to the casing.
