Usage:

735C LFJ

悬架没有保持正确的悬挂高度

可能原因:

  1. 悬架油缸内的密封有泄漏。 泄漏将导致受影响的一侧悬挂高度降低。

    • 有关悬架油缸的信息,请参阅拆解和装配机器系统, UENR4229, "740C 推料器铰接式卡车"。

    • 有关悬架油缸的信息,请参阅机器系统拆解和装配, UENR4228, "735C 和 745C 铰接式卡车"。

  1. 液压油从悬架油缸泄漏。 泄漏将导致受影响的一侧悬挂高度降低。

    • 请参阅技术规格 - 印度, UENR4225, "735C 铰接式卡车机器系统技术规格(组合式)"和系统操作/测试和调整, UENR4226, "735C 铰接式卡车机器系统操作/测试和调整(组合式)"。

底盘悬挂过硬或过软

可能原因

  • 一个或两个悬架油缸的充灌压力不正确。

  • 悬架高度不正确。

  • 检查每个悬架油缸有无氮气泄漏。 氮气泄漏很难检测。 由肥皂和水配成的溶液可用于检测泄漏。 确保阀芯和阀体四周无泄漏。 确保阀盖就位。 确保将阀盖拧紧至 3 至 5 N·m(27 至 44 lb in)的扭矩。

注: 对于上述任何可能的原因,请参阅技术规格 - 印度, UENR4225, "735C 铰接式卡车机器系统技术规格(组合式)"和系统操作/测试和调整, UENR4226, "735C 铰接式卡车机器系统操作/测试和调整(组合式)"
