Description

technical field

[0001] The invention relates to a shock absorber oil. Background technique

[0002] The development trend of the world's automobile products is towards the direction of energy saving, low pollution, improving reliability, durability, driving safety, riding comfort and ease of operation.

[0003] Many technical performances of a car, such as ride comfort, maneuverability, stability, etc., all depend on the choice of suspension characteristics. Suspension characteristics have to address three main issues, namely the selection of the best characteristics of the elastic, guiding and damping elements. The damping element refers to the shock absorber, and the good characteristics of the shock absorber can ensure the best characteristics of the suspension. The shock absorber oil is one of the main factors that affect the performance characteristics, high temperature characteristics, low temperature characteristics and anti-foaming properties of the shock absorber....
