集装箱正面吊的转向系统对其行驶安全至关重要,若转向系统出现故障,往往会造成重大的事故。本文以DRF400-450型卡尔玛集装箱正面吊为例,介绍全液压转向系统的工作原理及常见故障的解决方法。1.工作原理全液压转向系统巾液压泵1、优先阀2、梭阀3、转向器4、转向阀5、转向缸6以及扪关 The front suspension system of the container is crucial to the safety of the vehicle. If the steering system fails, it often leads to a major accident. In this paper, the DRF400-450 Kalmar container positive case is taken as an example to introduce the working principle of the full hydraulic steering system and the solution to common faults. 1. Working principle Full hydraulic steering system towel pump 1, priority valve 2, shuttle valve 3, steering gear 4, steering valve 5, steering cylinder 6 and the palmar
