摘 要本次设计的题目是北方奔驰前四后八自卸车改装设计。以二类底盘为基础，在此基础之上，进行改装设计。北方奔驰前四后八自卸车近几十年来它在国内外获得迅速的进展与普及，它最大的优点是实现了卸货的机械化，从而提高卸货效率。不仅可以减轻工人劳动强度，还可以促进国家的经济建设速度，关系到国家重点建设项目的建设和进展。同时在自卸车讨论和生产过程中，也带动了钢铁，化工等其它很多行业，又提供了大量的工作岗位，减轻就业压力，并日趋完善，成为系列化多品种的产品。因此，自卸车的进展是很有必要的。所以本文以北方奔驰前四后八自卸车为设计题目，设计的主要内容有以下几个方面,确定自卸车的总体设计方案，对举升机构进行选择，对液压控制系统的进行设计，对车厢的结构及副车架进行设计等。最后所设计出来的自卸车能够承载 15 吨的货物的结实耐用的产品。关键词：自卸车；车厢；改装；副车架；前四后八ABSTRACTThe design on the topic of north Benz 8×4 dump design modification. Second class based on chassis, based on this, the modification. North Benz 8×4 dump in recent decades it at home and abroad and the development of the speedy popularization, its biggest advantage is realized the mechanization of discharge, so as to improve the efficiency of discharge. It can not only reduce labor intensity, also can promote the country's economic construction speed, related to the national key construction project construction and development. At the same time in the research and production equipments in the process, also contributed to the steel, chemical and other many industries, and provide a great deal of the work, reduce the employment pressure, and improve, become a series of many varieties products. Therefore, the development of tipper is very necessary. So this paper to north Benz 8×4 equipments for design topic, design of the main content in the following aspects, determine the dump overall design scheme for the lifting mechanism of choice of hydra...
