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).

Object: To provide a technique whereby it is possible to both shorten the overall length of a power transmission device and reduce the number of components of the power transmission device. Resolution Means: A power transmission device (20) is configured so that the power of the motor rotational shaft (14) is transmitted to the axles (WS, WS) via the second input shaft (26) and the second idler shaft (59). Additionally, on the second idler shaft (59), the sliding contact portion (59a) is provided with which the brush member (70) slidably contacts. Among the shaft supports for supporting the shaft members, the housing side second input shaft support (64) and a portion of the second idler shaft support (65) which are formed in the housing (32) are disposed within the flywheel housing space (FAS). Moreover, the brush housing wall (32d) is formed integrally with the housing side second idler shaft support (65), and the interior (32d') of the brush housing wall (32d) is allowed to communicate with the outside air via the flywheel housing space (FAS) and the notch (32b"). As a result of this configuration, it is possible to prevent unnecessary increases in the overall length of the power transmission device (20), and there is no need to provide dedicated components such as a breathing pipe or the like.

The invention mainly relates to a spiral spring (36) of a brush holder for a motor vehicle starter. Said spiral spring includes: - a rolled-up portion (37) having a plurality of turns (371); and - an arm (39) for engaging one surface of a brush of the brush holder. The invention is characterized in that said spiral spring (36) also comprises a means (42) for reducing the friction between at least two adjacent turns (371) of said rolled-up portion (37).
