Abstract

The invention relates to a directional power-assisted oil composition and its application and mainly solves the problems of poor compatibility between a directional power-assisted oil and a rubber sealing member and the fault of a power steering system due to deformation or failure of the rubber sealing member with the application of a power-assisted oil composition in the power-assisted steering system in the prior art. The directional power-assisted oil composition comprises the following components of: by weight, a) 0.1-5 parts of boron polyisobutylene succinimide; b) 95-99.9 parts of base oil. By the adoption of the technical scheme, the problems are greatly solved. In addition, the technical scheme can be used in the industrial production of the directional power-assisted oil composition provided by the invention.

Description

technical field [0001] The invention relates to a steering oil composition and its application. Background technique [0002] In order to assist the driver to adjust the direction of the car and reduce the intensity of the steering wheel for the driver, almost every car is equipped with a power steering system. There are many forms of power steering systems in cars, but most cars now generally use hydraulic power steering systems. The hydraulic power steering system uses the pressure energy of the liquid to transmit energy, and the core component is the hydraulic pump; the steering oil is used as the transmission medium to transmit energy. When the car is turning while driving, the power steering system will generate high oil pressure, which will be sent to the steering gear through the steering oil to play a role in assisting. In addition, the steering oil also plays the role of lubricating the hydraulic pump and steering gear, heat dissipation, and rust prevention. [0...
