分析汽车悬架系统的未来发展前景

1、 分析汽车悬架系统的未来发展前景是高速公路的发展对汽车的操纵稳定性、平顺性、安全性提出了更高的要求，对空气悬架国内市场产生了很大的促进作用。此外，重型汽车对路面破坏机理的研究及认识进一步加深，政府对高速公路养护的重视，限制超载逐步在国内各地受到重视，使空气悬架在重型车市场的应用也将进一步扩大，为适应高速公路运输的需要，高级客车和大型载货车都必须使用空气悬架。Highway development on vehicle handling stability and ride comfort, security, put forward higher request, the air suspen

2、sion had a great promoting role in the domestic market. In addition, the mechanism of heavy vehicles on the road deepened research and understanding, and the government's emphasis on highway maintenance limit overload in parts of the country step by step, make the application of air suspension i

3、n heavy truck market will be further expanded, in order to adapt to the needs of the highway transportation, high-end passenger cars and large trucks must use air suspension. 我国20012010年道路运输业发展规划纲要中明确提出：2005年全国营运客车总量达到163万辆，高级客车占10%以上；营运货车达到485万辆。 2010年全国营运客车总量达到220万辆，高级客车占25%以上；营运货车达到550万辆。交通部营运客车类

4、型划分及等级评定jt/t325-2002标准规定2002年 7月1日开始高档客车必须装用空气悬架。据交通部门有关规定，允许装用空气悬架的车辆承载量在额定轴荷的基础上增加10%。In 2001 2010 in China clearly put forward in the road transport industry development planning outline: 2005 national operating passenger car totaled 1.63 million vehicles, high-end passenger cars accounted for mo

5、re than 10%; Operation of the truck by 4.85 million. 2010 national operating passenger car totaled 2.2 million vehicles, high-end passenger cars accounted for more than 25%; Operation of the truck by 5.5 million. Transport the division operating passenger car type and rating jt/t325-2002 standard on

6、 July 1, 2002 began to high-end passenger car must be equipped with air suspension. According to the relevant provisions of the transport sector, allowing equipped with air suspension vehicle capacity on the basis of nominal axle weight increased by 10%. 根据交通部营运客车类型划分及等级评定的规定，2007年1月1日起，大型高一级客、中型高二级

7、客车也要采用空气悬架，为我国空气悬架市场带来巨大商机。据估计，2007年我国大中型客车产量在11.5万左右(含客车非完整车辆)，其中空气悬架装配量达到2.11万套。我国大中型客车空气悬架的装配率也从2005年的8%，上升到2007年的18.4%。未来三年，随着2008年北京奥运会、2010的上海世博会和广州亚运会相继举办，我国客车市场对空气悬架的需求会进一步上升。第三次修改后的交通行业标准jt/t325-2006营运客车类型划分及等级评定更是将独立空气悬挂配置作为客车高等级的采用标准，为独立空气悬架产品的推广使用创造了一个良好的外部环境。According to the ministry of

8、 communications of operating passenger car classification and rating, on January 1, 2007, large high level guest, medium high level 2 passenger cars also want to use air suspension, bring huge business opportunities for air suspension in China market. It is estimated that 2007 large and medium-sized

9、 passenger car production in China at around 115000 (including bus nonholonomic vehicles), the amount of air suspension assembly reached 21100 sets. China's large and medium-sized passenger car air suspension assembly rate from 8% in 2005, rising to 18.4% in 2007. Over the next three years, as t

10、he 2008 Beijing Olympic Games, 2010 Shanghai world expo and guangzhou Asian games were held, demand for air suspension bus market in China will rise further. Third time revised transportation industry standard jt/t325-2006 "operating passenger classification and rating" is independent of a

11、ir suspension configurations as buses high grade of the standard, for independent air suspension products promote the use has created a favorable external environment. 空气悬架在The air suspension 而目前在汽车悬架系统方面，我国除了钢板弹簧悬架的设计及应用比较成熟以外，其它的悬架技术的应用绝大部分还处于车型引进、仿制或直接购买产品阶段。悬架产品的设计开发滞后，一方面，表现在设计手段落后， 计算 机应力分析、动态

12、仿真在 企业 中应用还较少；另一方面，没有建立一套完善的设计评价体系。在美国，由于空气悬架的普遍应用，已经成就了一批专门从事空气悬架设计、制造的悬架专业公司。我国 交通 行业标准营运客车类型划分及等级评定已经规定，高级大、中型客车要采用空气悬架，但既没有一家整车厂能独立设计出空气悬架成功地应用于整车，也没有一家悬架专业公司能够设计出并向市场提供成熟的复合土工膜空气悬架产品。虽然我国加入wto之后汽车及零部件产业会全面融入全球 经济 一体化，汽车行业可以实现全球采购，但是不能拥有悬架设计和制造的关键技术，整车的市场竞争力肯定会受到削弱。Now, in the aspect of the auto

13、mobile suspension system, our country in addition to the design and application of leaf spring suspension more mature, other suspension technology application, for the most part, is still in the introduction, generic or purchase products directly. Suspension product design development lags behind, o

14、n the one hand, the backward performance in the design, calculation, stress analysis and dynamic simulation in the enterprise application is less; On the other hand, there is no set up a perfect evaluation system design. In the United States, due to the widespread application of air suspension has a

15、lready accomplished a number of specialized is engaged in the suspension of air suspension design, manufacture specialized company. Transportation industry standard in our country the division operating passenger car type and rating has rules, advanced large and medium-sized passenger car to use air

16、 suspension, but neither a oems can independently design out of the air suspension has successfully applied in the vehicle, also no suspension professional company to design and provide mature air suspension products to market. Although automobile and parts industry after China's accession to th

17、e wto will be fully integrated into the global economic integration, the automobile industry can realize global sourcing, but can't have suspension design and the key technology of manufacturing, vehicle market competitiveness will be weakened. 虽然国内对空气悬架已经有了很多研究，部分产品已经开始批量生产，但是，从目前国内使用空气悬架的大客车来看

18、，普遍存在如下一些问题：气囊脱落、推力杆螺丝易松动、推力杆断裂、推力杆衬套寿命不长、水性油墨制动容易跑偏等等问题。国产货车还在使用传统的钢板弹簧或螺旋弹簧悬架。对空气悬架设计、空气悬架的可靠性分析、空气悬架与整车匹配技术以及 电子 控制系统控制 规律 的研究，是今后空气悬架的主要研究方向。Although domestic air suspension has a lot of research, some products have already started mass production, however, from the current domestic use of air s

19、uspension bus, universal existence some questions as follows: air bag easy to loose, fall off, thrust rod screw thrust rod fracture, thrust rod bushing life is not long, easy brake running deviation, and so on. Domestic freight still use traditional leaf spring or helical spring suspension. About air suspension design, the reliability analysis of air suspension, air suspension and the vehicle matching technique, and electronic control system control law research, are main research direction in t
