Abstract: front page image
(EN)The bearing material produced by impregnating in the porous metal or alloy layers, for example, copper or copper-like alloy layers formed by known means, for instance by sintering on the back of a metal plate such as steel, a composition containing 1 to 30% by volume of one or both of a lead-tin alloy, which contains 1 to 25% by volume of lead fluoride and 3 to 30% by weight of tin, and lead wherein the total of the said lead fluoride and lead is 2 to 35% by volume and, as the residual part, polytetrafluoroethylene (PTFE). The capacity of the bearing may be further improved by adding about 0.1 to about 5% by weight of at least one member of the additives consisting of molybdenum disulfide, tungsten disulfide, cadmium oxide, aluminium oxide, calcium fluoride, lithium fluoride, graphite, lead iodide, glass fibre, carbon fibre and phosphates. The bearing is especially suitable for being applied to the shock absorber of vehicles moving under changeable load.
(FR)Le materiau pour coussinet est produit par impregnation dans les couches de metal ou d"alliage poreux, par exemple, de cuivre ou d"alliage de cuivre, formees de maniere connue, par exemple, en frittant sur les dos d"une plaque metallique telle qu"une plaque en acier, une composition contenant 1 a 30% en volume - l"un ou les deux - d"un alliage plomb-etain, qui contient 1 a 25% en volume de fluorure de plomb et 3 a 30% en poids d"etain, et du plomb ou le total dudit fluorure de plomb et du plomb est de 2 a 25% en volume et le reste, du polytetrafluorethylene (PTFE). La capacite du coussinet peut encore etre amelioree en ajoutant environ 0,1 a 5% en poids d"au moins un des additifs tels que le disulfure de molybdene, le disulfure de tungstene, l"oxyde de cadmium, l"oxyde d"aluminium, le fluorure de calcium, le fluorure de lithium, le graphite, l"iodure de plomb, la fibre de verre, la fibre de carbone et les phosphates. Le coussinet convient particulierement aux amortisseurs des vehicules se deplacant avec des charges qui varient.
