| 摘 要： | 旁通流量式电控液压助力转向系统ECHPS(Electronically Controlled Hydraulic Power Stearing System)中的执行元件常采用电磁阀.对有、无前置稳压阀的电磁阀ECHPS助力特性进行理论分析和试验验证,结果表明,对于电磁阀带有稳压阀的ECHPS,高低车速下其助力特性曲线都可以达到系统限定的高压;而电磁阀无稳压阀的ECHPS,当高速时,系统中将不能建立高压.出于驾驶安全因素和整个系统设计的考虑,ECHPS中的电磁阀带有稳压阀更理想. |

| Abstract: | The actuator in by-pass flow type electronically controlled hydraulic power steering(ECHPS) was solenoid valve.Boosting characters of ECHPS whose solenoid valves with and without constant pressure valve were analyzed and measured.The results show solenoid valve with or without constant pressure valve in the ECHPS engenders different characters that all of the pressure in the character within the constant pressure valve would attain high value of the rated system pressure but would not without constant press... |
| Keywords: | solenoid valve constant pressure valve character electronically controlled hydraulic power steering |
