行驶液压系统

行驶液压系统利用机器液压系统中的七个主要部件提供机器行驶,包括:

  • 两个双向双速行驶马达,用于驱动终传动和附属的履带链轮

  • 主液压泵,可为行驶马达操作供油

  • 主控制阀中的三个控制阀滑阀,控制从主液压泵流向行驶马达的油流

  • 连接在操作员控制上的两个先导阀,控制机器前后移动和转向

  • 先导歧管,启用先导油分配,以便操作先导操作的行驶操纵杆/踏板

  • 控制歧管,包括双速行驶电磁阀

  • 回转接头,作为旋转上部结构(车体)和静止下部结构之间所有行驶系统液压油管路的旋转连接。

行驶系统的其他部件包括:

  • 直行电磁阀

  • 左右行驶压力开关

  • 双速行驶电磁阀
