简介:一、为什么要使用四轮定位专用调整角度零件?大家知道,车辆在出厂时其悬挂系统的定位角度(基本定位角度有7个)都是根据设计要求预先设定好的.这些定位角度共同用来保证车辆驾驶的舒适性和安全性.但是,由于车辆在售出并行驶一段时间后,这些定位角度会由于交通事故、道路坑洼不平造成的剧烈颠簸(特别是高速行驶时突然遇到不平路面)、底盘零件磨损、更换底盘零件、更换轮胎等原因而产生变化.一旦定位角度由任何一种原因产生变化,就可能产生诸如轮胎异常磨损、车辆跑偏、安全性下降、油耗增多、零件磨损加快、方向盘发沉、车辆发飘等不适症状.有些症状使车辆在高速行驶时非常危险.
简介:目前国外汽车零部件工业正在进一步向缩短产品开发周期、提高技术含量和通用化、降低成本、产品电子化等方向发展,其管理科学化、制造自动化、市场全球化水平很高,并广泛应用CAD/CAS/CAM等计算机技术。国外零部件工业经过重组、调整、优化等过程,已经形成了实力雄厚、产品质量优异、技术水平先进的大型企业集团,并率先实行同步开发、系统供货、模块化生产,成为汽车工业发展及零部件全球化采购的主要受益者。相比之下,我国汽车零部件行业还有很大差距,还不具备为国产汽车(尤其是轿车)全面配套供货的能力,参与国际竞争的能力很弱;在科技实力、销售业绩、产品技术含量、企业经营规模、全员劳动生产率等诸多方面存在几十年差距。我国已加入WTO,国际汽车及零部件生产企业正在大举进军我国汽车及零部件市场,虽然作为发展中国家我国在汽车领域尚有5年的保护过渡期,但不管从长远看,还是针对目前国内汽车零部件行业情况,我们都必须根据国际汽车零部件工业的发展,综合分析国外经验,结合我国实际情况,采取有力措施提高产品开发能力,加快人才培养,调整产业及产品结构,增加产品开发及生产现代化的资金投入,完善试验试制、生产管理、经营服务手段,开拓国内市场并积极参与国际竞争,尽快提
