浅析四轮转向系统在工程机械中的应用 Four wheel steering system is analysed in the application of engineering machinery 工程机械广泛地被应用到设计生产建设的各个方面。工程机械通常机身较长，转向不灵活，转弯半径大，与之相矛盾的是，工程机械的作业场地通常都狭窄，工作条件差，障碍物多，行驶路面凹凸不平，而且工程机械要求频繁转向。这就提出一个迫切的任务，即如何减小工程机械的转弯半径，增加工程机械作业行走的稳定性和可靠性，即我们需要一种转向性能良好的工程机械转向系统。 Engineering machinery is widely applied to design every aspect of production and construction. Engineering machinery is longer than the fuselage, usually not flexible steering, the turning radius is big, and paradoxically, engineering machinery operation site is usually small, poor working conditions, obstacles, more road uneven, but also frequently turned to mechanical engineering requirements. It puts forward an urgent task that how to reduce engineering machinery turning radius, increase walking engineering machinery operation stability and reliability, namely, we need a kind of engineering machinery to the good performance of steering system. 四轮转向系统是这些年来得到发展和应用的一种转向系统，从目前现状看来，进口的工程机械采用四轮转向技术屡见不鲜，可是国内对这一技术的研究几乎还处于空白。 2四轮转向系统的工作原理 四轮转向系统通常包括前轮转向、全轮转向、以及斜行转向三种模式。 Four-wheel steering system in these years the development and application of a steering system, from the current situation, it seems, imports of construction machinery with four-wheel steering technique, but domestic research on this technology is still in a blank almost. 2 four-wheel steering system working principle of four-wheel steering system usually includes the front wheel steering, all-wheel steering, and oblique lines to three modes. 前轮转向就是只有前轮进行左转或者右转。这是一种常用的转向方式，此时，前外轮的弯道行驶半径大，驾驶员易于用前外轮是否避过障碍来估计整机的行驶路线。 The front wheel steering is only front wheel to turn left or turn right. This is a common way of steering, at this point, the ocean shipping before driving bend radius is large, the driver is easy to use ocean shipping before ever avoid barriers to estimate the whole route. 全轮转向就是前后轮同时偏转的转向方式，此时，前后轮的偏转方向相反，即前轮左转时后轮右转，前轮右转时后轮左转。这种转向方式往往用于对机动性有特殊要求或机架特别长的机械。 All-wheel steering is the deflection of the front and at the same time
