Title (EN) LUBRICATING OIL COMPOSITION FOR MANUAL TRANSMISSION
(FR) COMPOSITION D’UNE HUILE DE LUBRIFICATION POUR TRANSMISSION MÉCANIQUE
(JA) 手動変速機用潤滑油組成物
Abstract: front page image
(EN)A low-viscosity lubricating oil for a manual transmission, which can simultaneously satisfy excellent shifting fork baking preventive properties and transmission properties despite the low viscosity and can realize fuel saving of automobiles, is provided. The lubricating oil composition for a manual transmission comprises a base oil, for a lubricating oil, having a kinematic viscosity of 4 to 6 mm2/sec at 100°C and, incorporated into the base oil based on the total amount of the composition, (A) 0.14 to 0.20% by mass, in terms of magnesium element, of magnesium sulfonate, (B) 0.14 to 0.18% by mass, in terms of zinc element, of a specific zinc dithiophosphate, (C) 0.3 to 0.5% by mass, in terms of sulfur element, of a sulfur-containing compound, and (D) 0.02 to 0.05% by mass, in terms of phosphorus element, of an alkyl phosphite. The lubricating oil composition has a kinematic viscosity of 25 to 30 mm2/sec at 40°C.
(FR)Il s’agit d’une huile de lubrification à faible indice de densité pour transmission mécanique, offrant d’excellentes propriétés contre l’échauffement de la fourche de changement de vitesse, d’excellentes qualités de transmission, malgré son faible indice de viscosité, tout en permettant de réaliser des économies de carburant. La composition de ce lubrifiant pour transmission mécanique comprend une huile de base pour lubrifiants présentant une viscosité kinématique de 4 à 6 mm²/sec à 100°C et, incorporés à l’huile de base, en proportion du volume total de la composition, (A) 0,14 à 0,20 % de la masse de sulfomate de magnésium, en termes d’élément magnésium, (B) 0,14 à 0,18% de la masse d’un dithiophosphate de zinc spécifique, en termes d’élément zinc, (C) 0,3 à 0,5% de la masse d’un composé contenant du sulfure, en termes d’élément sulfure, et (D) 0,02 à 0,05% de la masse de phosphite alkyl, en termes d’élément phosphore. La composition de ce lubrifiant présente un indice de viscosité kinématique de 25 à 30mm²/sec à 40°C.
(JA)低粘度であっても優れたシフトフォークの焼付き防止性と変速特性を両立し、自動車の省燃費化を達成し得る低粘度の手動変速機用潤滑油として、100℃の動粘度が4~6mm/sである潤滑油基油に、組成物全量基準で、(A)マグネシウムスルフォネートをマグネシウム元素量換算で0.14~0.20質量%、(B)特定のジチオリン酸亜鉛を亜鉛元素量換算で0.14~0.18質量%、(C)硫黄を含有する化合物を硫黄元素量換算で0.3~0.5質量%、及び(D)アルキル亜リン酸エステルをリン元素量換算で0.02~0.05質量%を含有して成り、かつ40℃における動粘度が25~30mm/sである手動変速機用潤滑油組成物が提供される。
