A lubricating composition comprising a base oil of mineral and/or synthetic origin in combination with a friction-reducing additive combination comprising molybdenum disulphide, zinc naphthenate and one or more metal dithiophosphates, and optionally one or more metal dithiocarbamates. A lubricating grease comprising such a composition in combination with a thickener, which may be a urea compound, a simple lithium soap or a lithium complex, is particularly suitable for lubricating constant velocity joints such as constant velocity ball joints.
Composition lubrifiante comprenant une huile de base d'origine minérale et/ou synthétique associée à une combinaison additive à réduction de frottement contenant du bisulfure de molybdène, du naphténate de zinc et un ou plusieurs dithiophosphates métalliques, et éventuellement un ou plusieurs dithiocarbamates métalliques. Une graisse lubrifiante de cette composition associée à un épaississeur, qui peut être un composé uréique, un simple savon de lithium ou un complexe de lithium, s'avère particulièrement utile pour la lubrification des joints homocinétiques, tels que les joints à rotule homocinétiques.
