Abstract

The present invention relates to a hydraulic-transmission- braking three-use lubricating oil composition, which is prepared by mixing the following raw materials, by weight, 85-98% of high viscosity index base oil, 0.1-5% of an extreme pressure wear resistance agent, 0.1-4% of an antioxidant, 0.1-3% of a metal deactivator/antirust agent, 0.1-5% of a friction modifier, and 0.1-2% of a dispersing agent. The hydraulic-transmission- braking three-use lubricating oil composition has beneficial effects of good low temperature fluidity, friction reduction, wear resistance, corrosion resistance, rust resistance, emulsification resistance and foaming resistance, and can meet requirements of universal hydraulic transmission oil used by large-medium-sized tractors and construction machinery so as to achieve complete lubricating protection on hydraulic parts, transmission parts, gear parts, power output parts and braking parts, such that a long service life is provided, equipment operation stability is easily improved, and energy saving and consumption reduction are provided.

Description

technical field [0001] The invention relates to a hydraulic-transmission-braking three-week lubricating oil composition. Background technique [0002] The lubricating oil used in early tractors was relatively simple, only engine oil and gear oil. Due to the continuous improvement of tractors, the transmission system and hydraulic system have been added, and the oil used in the system has developed from independent oil products to sharing the same oil product. Most modern tractors use oil-immersed multi-disc clutches, and use this wet brake device to replace the original dry brake device. After the wet brake device is used, it develops to the transmission, hydraulic pressure, brake, and clutch share the same oil, which requires the tractor transmission system oil to have better extreme pressure performance and friction performance. It must meet the needs of gear transmission lubrication and hydraulic pressure. The lubrication of the system must also meet the oil requirement...
