Matching of Hydraulic Power Assisted Steering System in the Gear and Rack Type Passenger Vehicle

Based on the importance of the gear and rack type hydraulic power assisted steering system, the relationship between the steering resistance and the vehicle speed is calculated by the overall layout input data and measured data. According to the analysis results of the steering resistance, the steering pump and the steering gear are matched, and the characteristic curves of these two parts are adjusted and matched. Then, the steering system output are optimized, the results meet the requirements of the steering resistance curve. Finally, combining empirical formulas and theories, an effective method which can build system model for matching analysis is obtained.
