【摘要】 助力转向泵性能的好坏直接关系到汽车转向系统是否能正常运行。目前使用广泛的双作用叶片泵存在着较大的能量浪费;而单作用叶片泵却由于输出流量可随负载变化,可以减少其能量损耗。故本文提出用单作用叶片泵代替双作用叶片泵,优化设计配流盘并对其配流特性进行仿真。仿真结果表明:该转向泵具有良好的预升、卸能力,而且可以满足变工况调节。针对单作用叶片泵流量脉动较大、定子受力不好的情况,本文对其流量特性和定子力学特性进行研究分析,得出结论:叶片数的奇偶性与叶片泵的流量脉动没有直接的关系;叶片数为偶数时,定子在X轴向的所受作用力不但要比其为相邻奇数时的小,而且方向恒定。此外,本文运用软件SolidWorks对转向泵进行三维实体造型、虚拟装配和干涉检查,及时发现设计中的错误与不足之处,以避免将来在加工装配过程中人力、物力、财力不必要的浪费和损失。 总之,本文对解决车辆能耗问题具有一定的实际意义,同时对复杂液压元件的虚拟设计有着重要的参考价值。更多还原

【Abstract】 The quality of power assisted steering pump influences the automobile steering systematic normal running directly. The double action vane pump using extensively at present has great energy waste; however the single action vane pump, owing to output flow varying with load, can reduce energy waste. So this text adopted single action vane pump to replace double action vane pump, optimized port plate design and emulated its distributing flow characteristic. The result indicated that this steering pump had nicer boosting and unloading pressure ability in advance and met to adjustment running condition changing. Aimming for the condition that flow fluctuation of the single action vane pump is too large and force stator of it suffering is not satisfying, this text studied the pump’s flow characteristic and mechanics characteristic of its stator and drawed the conclusion that vane number is odd oreven number has no relation with flow pulses when vane number is even number, force the stator suffering along the X anxis is less than when vane number is neighboring odd number and its direction is constant. In addition, this text used the software SolidWorks to build the three-dimensional model of the steering pump and carry out fictitious assembly and intervention check in order to find the mistake and lack in the design in time, thereby avoiding the waste and loss of manpower, material resources, financial resources in the course of processing and assembling in the future.In a word, this text has certain actual meanings in solving the vehicle energy consumption problem. At the same time, there is important reference value to the fictitious design of the complicated hydraulic pressure component.更多还原
