High-tech safety for compact cars
:  zaoche168.com   2008年12月14日

20081月新德里举行的印度汽车博览会对于制造商来说是展示各自汽车安全新技术和新部件一个好机会。这些技术包括新的高性能刹车装置,车辆稳定技术和驾驶辅助系统。在车展上,零部件供应商Continental (大陆)重点突出了他们对于车辆安全的关注,展示了集合了刹车,底盘和乘坐者保护系统的智能技术。

小型车市场发展

在下一个十年中,汽车工业将注意力集中在经济型轿车上,特别是亚洲市场的发展。根据预测,零售价格低于14,500美金(105,000人民币)的轿车生产将从现有650万辆增70%,到2017年到达大约1100万量。

“为了对于需求作出快速反应,我们将关注顾客定制和针对特定市场的解决方案。”Continental(大陆)公司底盘和安全部门Ralf Cramer博士说。“人们需要的是安全,我们的方案是直接进入这些市场,将我们各种汽车专业技术转化为符合当地需求的零部件和系统。”

更小更轻的刹车

小型轿车市场的发展制造了开发更小,更轻,同时具有经济适用性的刹车的需求。较低的发动机动力输出和较小的车辆总质量允许刹车系统减小尺寸,从而导致原材料消耗的减少。根据这种趋势,Continental(大陆)公司开发了新的ABS(防抱死系统)。该系统是在原有的ABS MK70系统上改造,但是大约只有原尺寸的一半。

Continental(大陆)公司的亚洲驱动部门(Asian Base Actuation)的制动驱动装置汇集了众多降低成本的建议。使用该系统情况下,真空气缸可以用更薄的和材料和隔膜。双管路控制泵活塞可以采用钢材料的而不用铝的,也可以降低成本。整个控制缸架由更薄但是相同耐用的材料制成。液压刹车系统20076月,Continental(大陆)公司和印度RICO汽车工业公司签订了合资协议,在印度建立一个液压刹车系统工厂,在两个阶段的第一个阶段达到4300万美元(3亿1500万人民币)的销售量。该合资公司是两公司平等合作所建立的。工厂将在2008年的第四季度开始大规模液压刹车系统的生产,并在距新德里不远的Gurgaon雇佣大约450名员工。

2008年竣工时,工厂将生产液压刹车产品,提供适于各种型号汽车的包含前后轴盘式制动器,鼓式制动器,控制缸,制动助力器和压力传感比例阀的服务,这些将提供给印度的代工贴牌客户。工厂的计划年生产能力是100万套刹车驱动单元和200万套刹车制动钳,50万套压力传感分配阀。

完成之后,工厂的第二阶段将产生一年9400万美金(6亿8200万人民币)的营业额并将雇佣625个员工。

High-tech safety for compact cars

The Auto Expo India held in New Delhi in january 2008 was an opportunity for manufacturers to showcase new technologies and components for increased vehicle technologies and driver assistance the show,component supplier Continental highlighted the focus on safety by bringing together intelligent technologies for brakes,chassis and occupant protection systems.

The growth of the small car market In the next decade,the automotive industry is set to focus on affordable cars-especially in the growth markets of is predicted that the production of cars with a retail price of less than USD 14,500(RMB 105,000) will increase by 70 per cent from the current figure of around 6.5m,to approximately 11m by erable increases are also predicted for Eastern Europe and South America.

"To respond quickly to this demand,we will focus on custorn-tailored,market-specific  solutions",says Dr Ralf Cramer,president chassis safety division,Continental,"What people want are safe,yet affordable we strongly believe that driving safety should be made available to each and every one,our solution is to go directly into these markets and to translate our extensive expertise in vehicle technology into components and systems that correspond to local needs."

Smaller and lighter brakes

The growth in the small car market has created the need to develop smaller and lighter brakes that are also lower engine output and lower overall weight of small cars allow braking systems to be downsized,resulting in reduced material light of this trend,Continental has been developing the new ABS system has been based on the existing ABS MK70 system,but is roughly half the size.

The brake actuation mechanism of ABA (Asian Base Actuation) from Continental incorporates a number of detailed proposals for reducing this system,the vacuum cylinder can be constructed using a thinner material and a thinner membrane.A steel dual master cylinder piston can be used instead of the aluminium version,which also keeps costs whole master cylinder housing is constructed with thinner,but equally durable material.

Hydraulic brake systems

In June 2007,Continental signed a joint venture agreement with RICO Auto Industries,India,to build a hydraulic brake systems plant in India,in a two step approach generating sales of USD 43m (RMB 315m) in the first joint venture is an equal partnership between the two plant will begin mass  producing hyraulic brake systems in the fourth quarter of 2008,employing around 450 staff in Gurgaon near New Delhi.

When construction is completed in 2008,the plant will produce hydraulic brake products and services consisting of calipers for front and rear axles,drum brakes,master cylinders,brake boosters and load sensing proportioning valves for vehicles of all classes, and supply to OEM customers in planned annual production 1.5m drum brakes and 500,000 load sensing proportioning valves.

On completion, the second phase of the plant will have annual turnover of USD 94m(RMB 682m) and will employ 625 people.
