Abstract

The invention provides a lubricating oil composition for a motorcycle shock absorber. The lubricating oil composition comprises the following components in percentage by weight: 1-20% of viscosity index improver, 0-1.0% of extreme-pressure antiwear agent, 0.05-1.0% of antioxidant and antiwear agent, 0.001-0.01% of demulsifier, 0.0001-0.01% of antifoaming agent, 0.05-1.4% of pour point depressant and the balance of base oil. According to the invention, the lubricating oil composition has the advantages of proper viscosity index, good viscosity-temperature performance, good low-temperature property, excellent rubber compatibility, and good corrosion resistance and oxidation resistance, and can be also used for lubricating a bicycle saddle shock absorber.

Description

technical field

[0001] The invention relates to a lubricating oil composition, in particular to a lubricating oil composition used for motorcycle shock absorbers, and belongs to the technical field of lubricating oil additives. Background technique

[0002] The motorcycle shock absorber is mainly a double-tube hydraulic shock absorber. The working principle of the hydraulic shock absorber is that when the frame and the axle reciprocate, the oil in the shock absorber shell will repeatedly pass through an inner cavity. Some narrow pores flow into another lumen. At this time, the friction between the hole wall and the oil and the internal friction of the liquid molecules form a damping force on the vibration, so that the vibration energy of the body and frame is converted into heat energy, which is absorbed by the oil and the shock absorber shell.

[0003] The use of shock absorber lubricating oil composition can be divided into lubricating oil composition for motorcycle shock...
