Title (EN) TRANSMISSION LUBRICANT COMPOSITION
(FR) COMPOSITION LUBRIFIANTE DE TRANSMISSION
Abstract:
(EN) A lubricant composition comprising a) a synthetic poly-alpha-olefin base fluid; b) an organomolybdenum friction modifier; c) an alkylphosphorothiolate and a hydrocarbylamine anti-wear combination; and d) a dihydrocarbyl dithiophosphate extreme pressure additive and optionally one or more of e) a copper corrosion inhibitor; f) an anti-foam agent; g) a solubilizing agent; h) polymeric viscosity index improver; and i) an oligomeric viscosity modifier is highly suitable for use in the synchronizer of a transmission.
(FR) L'invention concerne une composition lubrifiante comprenant a) un fluide de base de poly-alpha-oléfine synthétique ; b) un modificateur de frottement à base d'organomolybdène ; c) un phosphorothiolate d'alkyle et une combinaison anti-usure à base d'hydrocarbylamine ; et d) un additif de pression extrême à base de dithiophosphate de dihydrocarbyle et éventuellement l'un ou plusieurs parmi e) un inhibiteur de corrosion du cuivre ; f) un agent antimousse ; g) un agent de solubilisation ; h) un améliorant d'indice de viscosité polymère ; et i) un modificateur de viscosité oligomère, qui est hautement appropriée pour une utilisation dans le synchroniseur d'une transmission.
