Problems solved by technology

In the 1980s, foreign countries began to apply the centralized lubrication system of vehicle chassis, but in China, due to the technical and economical impact of this system, it has not been widely used.
At present, lubricating greases for chassis mainly include extreme-pressure lithium-based greases and general-purpose lithium-based greases for automobiles, which cannot meet the pumping performance and low-temperature performance requirements of centralized lubrication systems for vehicle chassis
At present, there is no relevant report on the special grease for centralized lubrication of vehicle chassis in China.

Abstract

The invention relates to a lubricating grease composition specially for the centralized lubrication of a vehicle chassis, prepared from the following raw materials in percentage by weight: 78.4-84.1 percent of base oil, 9.4-11.4 percent of 12 - hydroxyl stearic acid, 2.3-2.7 percent of lithium hydroxide monohydrate, 0.3-1.0 percent of alkylated diphenylamine, 2.0-4.0 percent of sulphide isobutene, 1.5-2.5 percent of molybdenum dialkyl-dithiophosphate and 0.4-1.0 percent of dodecencylsuccinic acid. The lubricating grease specially for the centralized lubrication of the vehicle chassis has favorable extreme-pressure abrasive resistance, antioxidative performance, anti-corrosion behavior, low-temperature performance and pumping performance and can be suitable for lubricating all vehicle chassis using a vehicle chassis centralized lubrication system. The lubricating grease composition specially for the centralized lubrication of the vehicle chassis has simple preparation method and low production cost.

Description

technical field [0001] The invention belongs to the technical field of lubrication, in particular to a lubricating grease composition specially used for centralized lubrication of vehicle chassis, and is especially suitable for the lubricating grease of the centralized lubrication system of vehicle chassis. Background technique [0002] The vehicle chassis centralized lubrication system is a device that centrally provides lubricating grease for each lubrication point of the vehicle chassis. Compared with manual greasing, it has the advantages of automatic timing and quantitative lubrication, accurate greasing amount, reliable lubrication, reduced parking time, and high labor productivity. The outage rate of vehicles installed with the chassis centralized lubrication system has been significantly improved, and the maintenance cost has also been reduced. In the 1980s, foreign countries began to apply the centralized lubrication system of vehicle chassis, but in China, due to ...
