(1) 履带
(2) 活塞马达( 静液压)
(3) 传动链轮
(4) 车桥
(5) 惰轮
(6) 张紧装置
(7) 转向架

多地形装载机的底盘系统通过车桥 (4) 安装在下部机架上。 车桥允许底盘系统的每一侧独立于另一侧弯曲。

底盘系统包括以下部件:履带 (1)、活塞马达( 静液压) (2)、驱动链轮 (3)、车桥 (4)、引导轮 (5)、张紧器 (6) 和转向架 (7)。

活塞泵( 静液压)向活塞马达提供油流。 来自活塞马达的动力通过行星齿轮外侧终传动传递到驱动链轮。 驱动链轮接合履带上的凸耳,且履带围绕引导轮、转向架和张紧器旋转。

转向架 (7) 直接安装在底盘系统的机架上。

张紧器 (6) 调整履带上的张力。 请参阅操作和保养手册, "履带(橡胶)- 检查/调整",了解调整履带张力的正确步骤。

如果履带张力未正确调整,则可能会发生以下任何一种情况:

  • 履带可能打滑。

  • 履带上的驱动凸耳可能损坏。

  • 履带可能会脱落。

  • 履带可能会过早磨损。

  • 动力损失。

  • 轴承可能有故障。
