Long-life driving method for railway locomotive

The invention discloses a long-life driving method for a railway locomotive. The method comprises the following steps of S1, installation of a pantograph; S2, installation of an electromagnetic clutch; S3, conversion of electric energy; S4, measurement of the speed and pressure; S5, adjustment of the pantograph; S6, adjustment of the electromagnetic clutch. By means of the driving method, the locomotive speed and pressure are detected, a PLC controls an electric retractable rod to ascend and descend and controls the electromagnetic clutch to be turned on and turned off, running of a driving device is adjusted, and the purpose of long-life use is achieved. 本发明公开了种铁路机车用的长寿命驱动方法，其包括以下步骤：S1、受电弓的安装；S2、电磁离合器的安装；S3、电能的装换；S4、速度与压力的测量；S5、受电弓的调节；S6、电磁离合器的调节。本发明的驱动方法通过实施检测车速以及压力情况，通过PLC控制器控制电动伸缩杆的升降，电磁离合器的启闭，调整驱动装置的运行，达到长寿命使用的目的。
