【摘要】：針對(duì)傳統(tǒng)液壓助力轉(zhuǎn)向系統(tǒng)的壓力和流量損失問題,設(shè)計(jì)了基于負(fù)載敏感技術(shù)的液壓助力轉(zhuǎn)向系統(tǒng)。基于仿真軟件AMESim對(duì)負(fù)載敏感泵和液壓助力轉(zhuǎn)向系統(tǒng)進(jìn)行了建模。仿真結(jié)果表明:當(dāng)在直線行駛工況下,該系統(tǒng)以低壓、小流量的待機(jī)狀態(tài)輸出;當(dāng)有轉(zhuǎn)向需求時(shí),系統(tǒng)能根據(jù)轉(zhuǎn)閥開啟閥度,快速調(diào)節(jié)泵出口的壓力和流量,并且能夠滿足助力需求。基于負(fù)載敏感技術(shù)的液壓助力轉(zhuǎn)向系統(tǒng)在車輛行駛過程中能減小能量消耗,達(dá)到節(jié)能的目的。
[Abstract]:Aiming at the pressure and flow loss of traditional hydraulic power steering system. The hydraulic power steering system based on load sensitive technology is designed. The load sensitive pump and hydraulic power steering system are modeled based on the simulation software AMESim. The simulation results show that:. When you're running in a straight line. The system is output in the standby state of low voltage and small flow rate. When there is a steering demand, the system can quickly adjust the pressure and flow rate of the pump outlet according to the valve opening threshold. The hydraulic power steering system based on load sensitive technology can reduce the energy consumption and achieve the purpose of energy saving.
