For an automobile steering system, besides the requirements of safe and reliable operation, light operation, good maneuverability, high efficiency and energy conservation, the automobile steering system also needs to be capable of providing the best road feel under various working conditions (such as straight running, normal steering, fast steering, pivot steering and the like) according to different running speeds and road conditions.
A steering system for an automobile generally includes: steering gear, steering oil pump, oilcan, oil pipe and coupling. The energy required by the steering gear comes from a steering oil pump, and the steering oil pump transmits steering force through steering system oil, so that the performance of the steering system oil directly determines the performance of the steering gear. If the working pressure and flow provided by the steering oil pump are too low, the steering oil pump feels heavy or cannot move; when the working pressure and the flow provided by the steering oil pump are too high (the valve is blocked), the high-pressure oil can pierce the low-pressure seal, so that the steering engine leaks oil; therefore, the steering system of the automobile requires that the used steering system oil has excellent viscosity-temperature performance, extreme pressure abrasion resistance, rubber compatibility and proper friction performance under various working conditions and environments. If the steering system oil contains air or foam, the phenomena of noise and poor power assisting effect can be generated, so the steering system oil also needs to have good anti-foam performance, and simultaneously has good oxidation resistance and oil sludge dispersion performance to meet the requirement of long oil change period.
In view of the above, there is a need to develop an oil product having excellent viscosity-temperature properties, oxidation resistance, sludge dispersibility, extreme pressure antiwear properties, rubber compatibility, anti-foaming properties, friction properties, and being highly efficient and energy-saving for use in an automobile steering system.
