摘 要
目前国内外都对加油车这一新兴车种相当的重视,尤其是是在军事方面,等高科技的技术领域加油车的应用广泛。加油车以它方便,快捷,被人们所接受。所以加油车以后还是会离我们的生活越来越近,我们的生活已经离不开它的存在RL5040GLY加油车先从底盘开始入手通过对底盘的选择,选取出符合要求的二类底盘,并对车架和副车架的承重进行分析,确定副车架的尺寸。并根据二类底盘的满载质量计算出出罐体的大小。最后确定各个部件的组成,最后进行整车动力性,燃油经济型的计算

ABSTRACT
A tanker truck at home and abroad of all this new type much attention, especially in the military, is high-tech technological field widely fuel truck. According to understand, for international oil prices continue to rise, small flow the economic value of fuel truck increasingly highlights, in recent years flow tanker truck market demand to multiply, and tanker trucks often is in short supply, high-tech cutting-edge products are much rarer, so a tanker truck later still will leave our life more and more close, our life has without its existence
Based on the introduction to design a key, tank car main structure and cheer special equipment design and working principle. In the design process devastates reference other tank tank car the basic shape, select section of simple and small error "four sections of arc fitting elliptic" method to design vessel section. And considering the difficulties in carriage process inner tanks increase prevent slope board. In order to ensure transportation safety, need low temperature of heat BaoWenChe, referring to transport the principle, design have heat preservation thermal insulation layer. Finally, according to the quality of the tanks assembly of fuel truck chassis and the distribution of axle and hang a Hollywood, and vehicle fuel economy performance, were calculated
