辅助转向是这些机器上的一个附件。 辅助转向泵位于靠近左转向油缸的发动机端机架的左下侧。
辅助转向泵总成包括辅助转向马达 (1) 和辅助转向泵 (3) 。 辅助转向马达 (1) 是一个 24 VDC 马达。 马达 (1) 驱动辅助转向泵 (3) 。 马达 (1) 沿逆时针方向转动泵 (3) 。
辅助转向泵 (3) 为齿轮泵。 辅助转向泵 (3) 吸取进口 (2) 中的油。 这些油被吸过齿轮的周围。 这些油从出口 (6) 流出。
辅助转向泵上的安全阀 (7) 将辅助转向回路中的油压值限制为 135 bar (1957.5 psi)。
注: 在正常机器操作过程中，除非主转向泵发生故障，否则辅助转向泵和电动马达不会工作。
