内容简介：

3吨柴油动力货车设计（总体设计）摘 要随着国内轻型载货汽车市场迅速发展,轻型载货汽车是载货汽车发展的一个重要方向。载货汽车市场竞争的加剧,车辆开发过程中对性能控制工作的需求越来越强烈。根据本次设计的车型和技术参数要求及现有的生产技术水平，为降低生产成本，使该车具有良好的燃油经济性，操纵性和结构简单的特点；后桥、转向器、传动轴、差速器和制动器等部件的选择和布置参照了BJ1041轻型载货汽车的相应部件选择和布置设计。文中还对汽车进行了主要部件的运动校核和性能预测，包括转向轮跳动、传动轴跳动、转向拉杆与悬架导向机构的运动协调校核，以及汽车的动力性、燃油经济性、机动性、操纵稳定性、通过性、制动性和平顺性等的预测。一辆汽车性能的优劣不仅取决于组成汽车的各部件的性能，而且在很大程度上取决于各部件的协调和配合，也取决于总体布置；总体设计水平的高低对汽车的使用性能和产品的生命力起决定性的影响。关键词： 汽车，设计，总布置 ,性能3T DIESEL FUEL POWER DUTY VEHICLE DESIGN (OVERALL DESIGN )ABSTRACT Light-duty vehicle is an important tendency of truck development, tractor-semitrailer are playing an important role in long way transportation. Taking light-duty truck as the target, this dissertation presents contents and methods of a study on performance control at design stage.According the design of the car and the ability of the manufacture technology at the present,in order to deciline the cost of the production anmake sure the car had a better quality and proper price ; The choices and arrangements of rear axle, steering gear, propeller shaft, differential and brake, etc is referred to the related parts on BJ1041 light truck. The movement corrections of key parts and the performance predictions of main components have been fulfilled including steering wheel hop, propeller hop and the mechanical motion correspondency between steering drag link and suspension guiding mechanism, so do the performances of driving, fuel economy, flexibility, steering stability, mobility over unprepared terrain, braking and riding comfort.A car performance depends not only on the merits of the various components of car, but also to a large extent depend on various parts of coordination and mate ，also depends on the overall layout;The high or low levels of design play a decisive impact on vehicle perform
