车型:95款福特林肯城市V8轿车。 故障现象:轿车起动后尾部先下降后上升到正常高度。 故障检测:根据故障现象,首先检查空气弹簧,发现空气弹簧与空气弹簧电磁阀都是新的。经询问车主得知,此车在好几个修理厂修过未能解决问题,才来我厂维修。我们对整个故障过程思考后认为,某个地方漏气是肯定的,因空气弹簧和空气弹簧 相似文献

空气悬架系统是以空气弹簧为弹性元件。空气弹簧是在一个密封的容器内充入压缩空气(气压为0.5~1.0MPa),利用气体的可压缩性,实现其弹性作用的。这种弹簧的刚度是可变的,因为作用在弹簧上载荷增加时,容器内的定量气体受压缩,气压升高,则弹簧的刚度增大。反之,当载荷减小时,弹簧内的气压下降,刚度减小,故它具有理想的弹性特性。对客车而言,使用空气弹簧悬架可以提高乘坐舒适性,对货车或挂车而言,使用空气弹簧悬架可以更好地保护货物。 相似文献

空气悬架系统作为高档公路大客车的关键部件,已经在国外高档客车上普及,商用车上使用的比例也在迅速提升,其独特的变刚度、低振动频率、抗道路凹凸冲击等诸多优越性越来越受人们重视。目前国内没有一家企业能设计出成熟的产品,加快空气悬架的设计研发,尤其是电子控制空气悬架(ECAS)的研发是大势所趋,谁先掌握了汽车空气悬架的开发技术,谁先开发出配置空气悬架的成熟车型,谁就掌握了今后若干年内商用车市场的先机和主动。 相似文献

Looking at the future trends of the road traffic, one will recognize that the commercial vehicle participation will not decrease, although it is required from the environmental and social viewpoints. The reason is that the other means of freight transport (water, railway, air) do not provide the same flexibility as the road transport, and direct business interest of those companies, who are using this transport form is larger than the eventual loss caused by the penalties to be paid (taxes, compensation of higher axle load). This conflict is hard to solve, but the effect can be minimized. The commercial vehicle industry attempts to introduce systems to the vehicles, which are targeting on reduction of the environmental impacts caused by heavy vehicles. These systems, which are named generally as “intelligent chassis systems”, electronically control the operation of the chassis subsystems (engine, transmission, brake, suspension) and co-ordinate their operation on a higher level (vehicle controller, intelligent control systems, such as adaptive cruise control, video camera based lane change recognition system, etc.). This paper reviews the state-of-the-art of the commercial vehicle chassis systems, and tries to project their future development. 相似文献
