Abstract: This brush holder assembly for an electric machine includes a bearing-forming metal end cap (26) intended to be mounted on a carcass of the machine, and a set of members (28, 30, 32, 34) for electrical connection of the brushes mounted on the end cap (26) by means of rivets (50, 52) which each include a shank extending from one of the pieces consisting of the end cap and one of the members, passing through an orifice formed in the other piece and folded over against the latter. The shank is made of the same material as the piece from which it extends and includes a closed head.

Abstract: Of application for suspension and steering systems and/or stabilizer bars which are located in the vicinity of a source of excessive heat generation such as a brake, it basically incorporates a thermal protector (9) integrated in the ball joint which presents a series of flexible radial plates (10) on its upper face defining interiorly a circular opening (11) which is attached to a connecting ring (12) previously fixed to the neck (7) of the dust boot (6) by overinjection or pressure and/or gluing, so that the thermal protector (9) covers the dust boot (6) in order to protect it from the high temperatures generated in the surrounding area.

Abstract: It incorporates a body (1) formed in sheet metal by stamping with reduced thickness and maximum inertia, and consists of a modular element ready for mounting which incorporates: a ball joint (2) located inside an external front housing (5) in which it is coupled by means of a lower socket (6) and a cover (7) which fit together and are welded by laser, a front silent-block (3) which reveals a cylindrical body from the surface of which some pairs of securing flaps (11) project radially which are inserted in a slot (8) defined in a concavely curved front housing (9), folded and welded by laser welding, and a rear silent-block (4) which is incorporated in a rear housing (12) by means of some press-fit bushings (15).

Abstract: The electric machine includes a collector (60), a brush-holder assembly comprising an end cap (26) and a set of members (28, 30, 32, 34) for electrical connection equipped with guide cages (36, 38, 40, 42) suitable for accommodating a respective brush (44), in which a member (64) for limiting the radial displacement of the brushes in the absence of a collector is provided, the dimensions of the limiting member (64) being suitable for obtaining a tight fit of this member on the end cap (26). Application for the mounting of a brush holder for a motor-vehicle starter.

Abstract: The motor vehicle starter (10) has a casing (18) in which there is arranged an electric motor (12) which rotates a coaxial starter head (22) with the interposing of an epicyclic gearbox (34) including a ring gear (44) made of rigid material (M1) which is housed at least partially in a cavity (58) in the casing and which has an internally toothed cylindrical annular skirt (46) closed at its front axial end by a radially oriented transverse wall (50) with a hole at its centre (52) for the output shaft (42) of the gearbox to pass; the ring gear (44) has pins (P) moulded from a flexible material (M2), notably elastomer material, which are interposed between the ring gear (44) and complementary portions (68) of the cavity (58) of the casing (16, 18) in order to immobilise the ring gear (44) rotationally with respect to the casing (18) and provide a function of torsion damping between these two components (44, 18).
