| 摘 要： | 基于流量递减式球活塞车辆转向泵的结构和工作原理，从力平衡和流量平衡出发，构建了该泵的动态特性方程组，据此对该泵的变流量控制特性进行了仿真和试验研究。结果表明，该泵转速在超过开启转速之后，泵的输出流量增速不升反降，与车辆行驶速度越高，需要的转向力越低的实际工况完全同步，为智能化车辆转向泵的研制奠定了基础。

| Abstract: | Based on the analysis of the structure and working principles of a ball piston vehicle steering pump, the dynamic characteristic equations of the new pump were set up from the force and flow balance. Then based on those equations, the corresponding simulations and experimental investigation were carried out. The results indicated that the output flow would decrease drastically when the rotation speed of the pump exceeded the opening speed of rotation, which met the requirements of the vehicle steering working condition. |
