Embodiment Construction

[0034] refer to figure 1 with 4 , describes a brush holder 1 for a motor vehicle starter according to the invention.

[0035] The brush holder 1 comprises a support plate 2 having an annular form, on which is fixed a set of brush holders 3.1-3.4, each brush holder serving as a receptacle for a brush 5.1-5.4. The axis X of the support plate 2 corresponds to the axis of the brush holder 1 .

[0036] The support plate 2 and the brackets 3.1-3.4 it supports are fixed on a cover 6 which forms the rear bearing for the rotor shaft of the electric machine. The cover 6 comprises, for example, two protruding ears 7 , a hole for the passage of a connecting rod (tierod) passing radially through each ear 7 , said connecting rod being screwed on the front bearing of the starter. The two protuberances 8 obtained from the ears are configured to be folded back against the head of the motor during tightening of the connecting rod to improve the mechanical retention of the assembly.

Abstract

The invention relates mainly to a brush holder (1) of a rotary electric machine comprising at least two boxes (3.1, 3.3) which are each used respectively as a housing for a brush (5.1, 5.3), and an inter-brush connector (20) to which braids (17.1, 17.3) of said brushes (5.1, 5.3) with the same polarity are intended to be welded, the brush holder being characterised in that said boxes (3.1, 3.3) are each provided with at least one tab (25) extending axially relative to an axis of the brush holder (1), and in that said inter-brush connector (20) is held by resilient deformation against the tabs (25) of the brush boxes (3.1, 3.3). The invention also relates to the corresponding starter.

Description

technical field [0001] The invention relates to a brush holder for an electric motor of a vehicle, and to a corresponding starter. [0002] The invention has a particularly advantageous but not exclusive application in motor vehicle starters, in particular starters installed in vehicles equipped with a stop and restart (stop and start) function of a thermal engine. Background technique [0003] In a known manner, a brush holder is fitted on the shaft of the starter rotor to cooperate with a current collector which is integral with the shaft of the rotor. [0004] The brush holder includes a support plate supporting a set of brackets, each bracket serving as a receptacle for a brush. Brushes made of conductive material provide power to the rotor by switching the current in the rotor's conductors. [0005] For this purpose, each brush comprises a face designed to rub against a conductive plate of the collector connected to the rotor winding, elastic means such as springs are...
