1、后置直推式自卸车的设计与实现摘要去年以来,我国专用车市场取得较好的经营业绩,全国395家改装车企业改装汽车23.06万辆,销售23.05万辆。自卸汽车27125辆,占总量的11.76%。随着国内基础设施建设需要不断增加,自卸车产量近年来一直保持较高产销量,在专用车综合产量中保持第一位置,但在种类、型式、材料运用方面与国外还有一定的差距。本文首先对自卸车的设计特点以及国内外发展现状做了相关的概述。具体分析介绍了自卸车的各种类型,逐层分析到后置直推式自卸车的特点、功能。根据题廿要求确定自卸车的总体结构,再根据设计要求确定后置直推式自卸车举升机构的主要
2、尺寸和质量参数。在设计过程中应时刻注意设计应满足加工简单,生产率高,经济性能好,制造成本低,工作寿命长等。在设计过程中及吋翻阅资料,咨询老师,尽量完成机构合理,质量良好,能正确、有效完成任务的后置直推式自卸车举升机。接着,从车厢的设计、举升机构的设计等方面进行了后置宜推式自卸车的总体设计,并对主车副车架进行了改装与设计。对整个后置直推式自卸车的外廓尺寸、轮距与轴距尺寸、前悬后悬以及整车的装载质量、整备质量、总质量和轴载质量进行了相关的计算与设计。关键字:自卸汽车,总体布置设计,副车架,轴载质量,举升机构AbstractSincelastyear,
