自行走液压全挂车液压电控设计

Hydraulic and Electric Control Design of Self-propelled Hydraulic Full Trailer

介绍了一种自行走液压全挂车,能实现空车自行走、重载拖行、辅助驱动、主动转向、被动转向、平台升降等。重点介绍了自行走液压全挂车液压系统原理,并分析了如何实现自行走和拖行走的切换及主动转向和被动转向的切换。最后介绍了电控原理并对多车并车模式下各车轮位转角进行了计算。

This paper introduced a self-propelledhydraulic full trailer, it can walk by itself when without load, towed by tractor when with loadand auxiliarydrive. It enables active steering and passive steering. The principle of hydraulic system of self-propelled hydraulic full trailer isintroduced emphatically, and analyzes how to realize selfpropelling and towing switching and active steering and passive steering switching.Finally, the principle of electric control is introduced and the wheel position angle of nmlti-vehiele parallel mode is calculated.
