摘 要 汽车工业的发展是经济社会发展的必然，而经济社会的发展，又对汽车的使用功能不断提出新的要求，使汽车在社会商品、信息、人员三种流通中起着重要的作用。汽车的经济效益不只在于汽车生产的本身，而是更集中体现在汽车使用和流通的全过程。油罐车是专用汽车的一种，而专用汽车是一种高科技产品，它将机械、电子、液压、化工、环保等各领域的先进技术模块化地集成在一个专用车底盘上，从而实现一定的特定功能所以专用车的生产特点是技术要求高、品种多、批量小、市场需求变化快。目前，罐车已经在运输上得到了广泛的应用。在北美，罐车主要负责液体货物的散装运输。北美铁道车辆中罐车占七分之一。在美国、加拿大和墨西哥，每年有220000辆车运送300万的装车量的货物。尽管通常罐车与危险品的运输有关，但50％的货物是非管制的食品和工业产品。在我国，罐车也得到了充分的应用，有高度专用化的运输酸的酸罐车、经过优化的用于运输乙二醇的乙二醇罐车、专门设计成运输液化石油气的液化石油气罐车、用于运输氯乙烯的氯乙烯罐车、运输谷物浆的谷物浆罐车等等。罐车运输已经影响到我们生活的每一部分，对国民经济的发展有着重要的意义。本次设计的油罐车主要用于装运柴油、汽油等易燃、易爆的液体，也可以运送食品油等其它油品。按罐体与汽车或挂车的连接方式分为半承载式罐车和承载式罐车；油罐汽车一般由二类汽车底盘、油罐、安全阀、输油管道等主要部件组成。 ：专用汽车；油罐；副车架；油泵；取力器 ABSTRACT Auto industry development is the necessity of the development of economy and society, and the development of economy and society, and for the automobile use function continuously put forward new requirements, make cars in social commodity, information, personnel three circulation plays an important role. The economic benefits of car lies not just in automobile production itself, but the more embodied in the whole process of car use and circulation. A tanker is a kind of special automobile, and special vehicle is a high-tech product, it will machinery, electronics, hydraulic, chemical, environmental protection etc advanced technology modular integration in a special automobile chassis, thus achieve certain specific functions so special automobile production features are high technical requirements variety, small batch, market demand change quickly. At present, in transportation tank has been widely used. In North America, tanker is mainly responsible for the goods in bulk liquid transportation. North American railway vehicles accounted for one in seven points tank. In the U.S., Canada and Mexico, each year 220,000 car shipping 300 million loading quantity of goods. Although usually tanker and dangerous goods transport related, but 50% of the goods are controlled food and industrial products. In our country, the tanker also got fully
