Abstract: The invention relates mainly to an assembly comprising a brush cage and a spiral spring (36), the spiral spring (36) comprising an axis (Y), a wound part (37) wound about the axis (Y) and an arm (39) extending from one end of the wound part (37), the brush cage comprising at least one lateral wall provided with an opening for the passage of the arm (39) through the lateral wall so that one end of the arm (39) can press against at least part of an end face of a brush, wherein the arm (39) comprises a first portion (391) of which the width (L5) measured along the axis (Y) is different from the width (L6) of the wound part (37) measured along the axis (Y) of the spiral spring (36).

Abstract: The invention relates mainly to a brush cage (13) for a brush holder (10) of an electric motor comprising:—two lateral walls (26) and a connecting wall (28) connecting the two lateral walls (26),—in which cage at least one of the lateral walls (26) has an opening (43) for the passage of a spring arm,—the lateral wall (26) comprising the opening (43) having a length (L0) measured between a first end (51) intended to be furthest from a commutator and a second end (52) intended to be closest to the commutator, wherein the opening (43) comprises at least a first portion (431) between the two ends (51, 52) which widens out towards the second end (52).

Abstract: The invention mainly relates to a spiral spring (36) of a brush holder for a motor vehicle starter. The 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 the spiral spring (36) also comprises a means (42) for reducing the friction between at least two adjacent turns (371) of the rolled-up portion (37).

Abstract: A brush-holder for a motor vehicle starter comprising at least one first electrically conductive cage receiving a first brush having a first polarity, at least one second cage receiving a second brush having a second polarity different to the first polarity, at least one support plate on which the first cage and the second cage are attached, the support plate being electrically connected to the second polarity, and a deformable heat-sensitive member that is deformable from a pre-defined temperature, wherein the deformable member is arranged so as to electrically insulate the first cage relative to the support plate and wherein it further comprises a means for moving the first cage or the support plate in such a way as to establish contact between the first cage and the support plate following a deformation of the deformable member.

Abstract: An electric motor brush holder for a motor vehicle starter includes a mounting plate, at least one cage mounted on the mounting plate, where the cage has a housing and at least one opening, at least one brush positioned inside said housing of the cage, and a conductive braid connected to the brush, said conductive braid passing through the opening of the cage, where the conductive braid is supported at least on the portion thereof passing through said opening.

Abstract: The invention relates mainly to an assembly comprising a brush cage and a spiral spring (36), the spiral spring (36) comprising an axis (Y), a wound part (37) wound about the axis (Y) and an arm (39) extending from one end of the wound part (37), the brush cage comprising at least one lateral wall provided with an opening for the passage of the arm (39) through the lateral wall so that one end of the arm (39) can press against at least part of an end face of a brush, wherein the arm (39) comprises a first portion (391) of which the width (L5) measured along the axis (Y) is different from the width (L6) of the wound part (37) measured along the axis (Y) of the spiral spring (36).

Abstract: The invention relates mainly to a brush cage (13) for a brush holder (10) of an electric motor comprising:—two lateral walls (26) and a connecting wall (28) connecting the two lateral walls (26),—in which cage at least one of the lateral walls (26) has an opening (43) for the passage of a spring arm,—the lateral wall (26) comprising the opening (43) having a length (L0) measured between a first end (51) intended to be furthest from a commutator and a second end (52) intended to be closest to the commutator, wherein the opening (43) comprises at least a first portion (431) between the two ends (51, 52) which widens out towards the second end (52).
