Improvement of the efficiency of hydraulic power steering

Abstract

The purpose of the study is to increase the reliability of the steering system. The article reflects scientifically based recommendations for improving the design of steering. The research method is theoretical studies performed on the basis of the provisions, laws and methods of theoretical mechanics, hydraulics, heat engineering, power flow theory and mathematical analysis. The article presents the results of theoretical studies on the temperature regimes of a hydraulic power steering (HPS), the results of which establish the analytical relation between the temperature pressure of the working fluid and the efficiency coefficient of the HPS. As a result, knowing the temperature of the working fluid, it is possible to determine the efficiency of the HPS in any of its operating modes. The analysis shows that in order to increase the efficiency of the HPS it is necessary to lower the temperature of the HPS working fluid. To this end, a device is developed aimed at improving the efficiency of the cooling fluid in the power steering and allowing increasing the efficiency of the HPS.
