Abstract

The invention relates to a heavy-load hydrodynamic drive lubricating oil composition, which especially can meet the lubrication demand of hydrodynamic drive equipment (including automatic gearbox, a hydraulic coupler, a hydraulic torque converter) used under extremely low-temperature conditions. The composition also adopts special multifunctional antioxidant and antifriction lubricant, ashless dispersant and anti-wear agent at extreme pressure except for base oil, and is compound together with special clean dispersant and antioxidant, thus giving full play to the synergistic effect among the additives. The lubricating oil composition has good low-temperature fluidity, antiwear property at extreme pressure and anti-oxidization stability, as well as certain anticorrosion and anti-rust properties and anti-emulsion property, thus meeting the lubrication demand of the automatic gearbox, the hydraulic torque converter and the hydraulic couple used under various special environment conditions.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition for hydraulic transmissions (gear boxes, reduction boxes and other gear transmission systems) used under different environmental conditions. technical background [0002] Among various mechanical transmission mechanisms, power is directly transmitted through gears, which has high efficiency and wide application. However, with the increasing use of vehicles, the comfort and convenience of driving have become the focus of attention. In order to overcome the lack of hard connection of gears, the application of automatic transmission was born, which mainly uses the hydraulic torque converter to cooperate with the traditional mechanical gearbox to realize the gear shifting function. As the core component of automatic transmission, hydraulic torque converter is not only widely used in vehicle gearboxes, but also gradually develops into hydraulic transmissi...
