摘要:
The invention mainly relates to a motor vehicle heat-engine starter including at least one electromagnetic contactor, including a positive output terminal, and at least one electrical motor. Said electrical motor includes: a stator including windings, each winding being wound around a pole piece so as to form a pole, at least one brush cage (43), at least one positive brush (35) mounted in said brush cage, an electrical path between said positive brush (35) and the positive output terminal (32), and at least one thermal protection (96) located in said electrical path, wherein said thermal protection is capable of disconnecting said two elements (93, 95) when the thermal protection has a temperature greater than a temperature threshold for electrically disconnecting said positive output terminal from said positive brush (35).

The invention mainly concerns a brush holder (10) for an electric motor, in particular the starter motor of a motor vehicle, comprising guide cages (13) for receiving the brushes (15) and a support plate (12) on which said guide cages (13) are positioned. Said guide cages (13) are made from an insulating material. Said brush holder (10) comprises legs (29) fixed on the support plate (12), around each of which a spiral spring (24) is intended to be mounted in order to exert a force on the brush (15) in such a way as to press said brush (15) against a collector.

The invention relates to a starter comprising an electric engine (11) which is connected to a starter drive assembly (30) with a planetary gear speed reducer (45) inserted therebetween. According to the invention, the reducer is housed inside a fixed ring gear (46) which comprises a centring ring (73) having a first support face (70) which is located in the same plane as the connection interface between the support (16) and the cylinder head (15). The invention is suitable for a motor vehicle starter.

The invention relates to an electric starter for an internal combustion engine comprising a housing, an electric motor comprising an inner shaft that is rotatably mobile in relation to the housing about a longitudinal axis, an output shaft driven by the inner shaft, and a reducer assembly rotatably connecting the inner shaft and the output shaft, said reducer assembly comprising a ring gear (46) fixed to the housing by means of an elastic connection. The elastic connection between the ring gear (46) and the housing comprises an elastic element (90) that is axially at a distance from the ring gear (46), and a rotatably connecting element (80) mounted axially between the ring gear (46) and the elastic element (90), the ring gear (46) being carried by the housing by means of the connection element (80), said elastic element (90) being able to absorb a coupling impact transmitted to the ring gear (46).

The front bearing (110) of a heat engine starter having an output pinion starter drive (120) comprises, in the front, a transverse wall (111) having an opening (112), for passing a body (122) of the starter drive (120) therethrough, and a cavity (200) for mounting a sealing joint (240), said cavity being set up on the inner periphery of the rear surface (400) of said front bearing. Said rear surface is configured so as to form a bearing abutment for the outer ring (231) of a rolling bearing (230) and moreover has at least one hollowed-out area (300) intended to be filled with grease so as to form a grease supply. Said hollowed-out area is mostly set up outside the cavity. A heat engine starter having an output pinion is characterized in that it comprises one such front bearing.

The invention relates to a method of mounting a retaining ring (21) on a rotating electric armature shaft. The inventive method consists in first mounting the retaining ring (21) on an axial shaft segment (27) which is located in an accessible mounting area between the groove (23) and the splines (15) of the starter drive assembly (10) and, subsequently, moving the starter drive assembly (10) axially towards the rest position such as to move the retaining ring (21) along the aforementioned shaft segment (27) as far as the positioning groove (23) comprising a service area with no radial access.
