本文讨论用于630kW级机场工作的化学消防车的功率分配车离合器的开发。因摩擦盘在100kPa接触压力下要求打滑,故作为大多数问题可以预见由于盘表面不够精确而减少了实际的接触面积。基于TEM和实际试验通过数值分析可推断出实际接触面积和离合器的温度。我们可以测定我们的分析和实验结果十分吻合。另一方面我们采用-ECMV(电子控制调节阀)(*1)用它来平稳控制车辆速度。此外我们还利用-电子系统代替机动联动装置可使维修简化。通过有效使用-微处理器,我们成功地增添了能防止不良使用的安全措施的保护功能和一个有效的故障诊断系统。
This article discusses the development of a power distribution car clutch for a chemical fire truck operating at a 630kW class airport. Because friction disks require slippage at a pressure of 100 kPa, it is foreseen as most problems that the actual contact area is reduced due to inaccurate disk surfaces. The actual contact area and the temperature of the clutch can be inferred by numerical analysis based on the TEM and the actual test. We can determine that our analysis is in good agreement with the experimental results. On the other hand, we use -ECMV (* 1) to control the vehicle speed smoothly. In addition, we also use - electronic systems instead of mobile linkage can make maintenance easier. With the efficient use of microprocessors, we have succeeded in adding protection features that prevent unsafe use of safety measures and an effective fault diagnosis system.
