摘要： The invention relates to a sliding contact piece for transmitting an electrical current with a density of between 15 A/cm and 50 A/cm , said element comprising copper particles and graphoid particles produced by grinding a mixture of graphite particles, preferably natural graphite, and organic binding agents. Said contact piece is characterised in that, in order to transmit the current for at least 2000 hours at a temperature higher than 100 DEG C, typically around 150 DEG C, the contact piece contains between 20 and 60 wt. % of copper particles and also particles comprising an additional metal pertaining to the group consisting of zinc, manganese and tin, in the form of metal or a compound of said metal.

摘要： The invention relates to a sliding electrical contact part comprising a base of carbonaceous material and copper. The invention is characterised in that the part is lead free and contains zinc and iron-based particles having a size of less than 500 µm. The inventive contact parts are particularly suitable for electrical devices which require high current densities and friction velocities, such as motor vehicle starters with a high power-weight ratio.

摘要： Procédé d'usinage in situ de la surface (1100) périphérique d'une pièce rotative tournant autour d'un axe xx' (1), dans lequel on utilise un dispositif d'usinage comprenant au moins une platine (12) solidaire d'un bâti et un porte-outil (11) muni d'un outil coupant (300), et monté sur ladite platine de sorte qu'il peut se déplacer suivant une direction YY' (3) sensiblement perpendiculaire à l'axe de rotation xx' (1). Le porte-outil est monté sur la platine (12) de telle sorte qu'il peut pivoter autour d'un axe orienté suivant une direction ZZ' (4) sensiblement perpendiculaire à la direction YY' et à l'axe de rotation xx'. En combinant une rotation autour de ZZ' et une translation suivant la direction de plongée YY' du centre de rotation (C) autour de ZZ', on impose à l'extrémité active de l'outil coupant (300) un déplacement dans un plan perpendiculaire à l'axe ZZ'. Le dispositif peut également se déplacer suivant le troisième axe XX'.

摘要： The invention concerns friction contact devices, such as pantographs, used for transferring electric current from a fixed electrical conductor, such as a catenary, to a stopped or moving railway car. More particularly, the invention concerns the friction element ( or friction strip ) of friction contact devices. The inventive friction strip is characterised in that its wear strip (2) comprises, entirely or partially, a carbon/carbon composite material (C/C), optionally impregnated with a metal such as copper or an alloy containing copper. The inventive friction strips are considerably less fragile than those of prior art based on graphite impregnated with copper. They also have a much higher wear resistance than those of prior art.

摘要： The invention relates to a sliding strip (1) comprising at least one contact strip (22, 22a, 22b) containing a first carbonated material which is resistant to abrasion, and a sheath (21, 21a, 21b) containing a second carbonated material having a thermal conductivity which is higher than or equal to 80 W/m.K. Part (24, 24a, 24b) of the surface of the contact strip (22, 22a, 22b) forms all or part of said contact surface (20). The inventive sliding strip enables operational costs (for example the maintenance cost of the catenaries) to be reduced, especially as a result of the low temperature when the current is collected in a stationary position.

摘要： The invention concerns mounting bracket (3) of pantograph bow contact (1), designed to bear a current collector (2), characterised in that it comprises, entirely or partly, at least an organic composite containing fibres and an organic matrix. The mounting bracket and the bow contact of the invention are lighter, more corrosion-resistant and easier to produce than those of prior art.

摘要： The invention relates to a brush-holder (1) for a rotating commutated electric motor, comprising a support (10), provided with a central hole (5) to permit the commutator through, for arranging perpendicular to the axis of rotation and n brushes (20), regularly distributed and associated with n radial brush guidance systems, n being a whole number of at least 2. Each brush is provided with grooves (25, 26) on the lateral face thereof (21, 22) and is connected to an elastic means (40). The support has n housings (50), each housing may house a brush and the associated elastic means with a base (49) essentially perpendicular to the axis and an upper open face parallel to the base. The upper open face is partially encased by two rigid sheets (60, 61) separate from the support but attached thereto such as to project over said upper open face and engage in the radial grooves (25, 26) of the brush thus trapping the brush and the elastic means thereof (for example a compression spring) in said housing.
