Research on Influence of Hydraulic Power Steering Gear on 0perating Feel under In-situ Steering Conditions
The operating feel of steering wheel directly affects the ease of vehicle handling.To address the problem of strong nonlinearity in the tyre resistance torque under in-situ steering condi-tions,the"magic-formula"is adopted for char-acterization,and the calculated results of the in-situ steering"magic formula"and the test results are compared and analyzed to obtain a good consistency.The influence of steering parameters on the operating feel of the steering wheel is analyzed.The analysis results show that,among the parameters of the steering gear,the distance from the original position of the end face of the valve core to the end face of the valve sleeve has the greatest influence on the operating torque of the steering wheel,the operating torque of the steering wheel increases with the increase of the wheel angle,but it will decrease slightly after reaching a certain value.
