735C and 745C Articulated Trucks Machine Systems Caterpillar


Calibrations (Cat ET)

Usage:

735C LFJ


简介

与机具或变速箱 ECM 相连的一些部件可以使用 Caterpillar 电子技师(Cat ET)来标定。

根据故障诊断与排除步骤或在标定的系统范围内更换部件的指示执行标定。

ECM 通过部件标定来确定正确的输出水平。 ECM 还通过此标定来确定正确的排量输入信号。

机器 ECM 标定

对机具 ECM 执行以下标定。

  • 惯性测量传感器标定 - 用于提供准确的机器级别信息,以便用于自动缓速控制。

若要访问机器 ECM 的标定步骤,建立 Cat ET 到机器的连接。 通过单击工具栏"服务",再单击"标定"导航至标定屏幕。 单击所需的标定。

一旦选择了特定标定,Cat 电子技师会为您引导整个标定步骤。

Cat 电子技师显示屏会列出 ECM 允许继续标定步骤前必须满足的初始机器状况。 遵循显示屏上的具体指示以完成标定步骤。

变速箱 ECM 标定

变速箱 ECM 控制以下标定:

  • 缓速器性能标定 - 缓速器控制标定步骤期间,系统软件将检测缓速能力。 通过在不同的水平接合缓速器电磁阀,直到检测到预期的发动机转速下降,来检测缓速能力。

  • 变速箱加注标定 - 变速箱离合器加注标定将微调通过阀控制的每个离合器阀。 如果离合器加注参数不正确,则可能显著影响变速箱换档质量。 为获得更高的一致性,校准程序是自动的。 变速箱离合器接合校准应在变速箱离合器充满校准前进行。
