引领中国汽车的轻量化时代—爱普车辆(中国)有限公司

随着石油资源的逐渐损耗,各国政府对汽车产业的节能和排放的要求也日益严格。除了采用混合动力、纯电动等新的能源方式,降低整车重量应用更多的轻量化技术和轻量化材料也是降低排放、节能环保一项直接有效的办法。

铝合金作为一种轻量化材料为广泛应用于航空航天和交通运输,以客车为例全铝车身的重量一般仅为钢制车身的60%左右,通过全铆接等连接技术实现整体框架结构,具有安全可靠性高、重量轻、强度刚性好等特点,所以燃油经济性和安全性都比钢制车身大幅提升。车身是客车的主要重量部件,现有铝合金轻量化方案已完全能实现车身的全铝化。

接下来,就让我们了解一下爱普全铝车身的工艺和优势。

    提高车身的强度,还要减轻车身的重量,这本身看似矛盾,但这却是爱普车辆全铝合金车身综合解决方案的特点所在。2015年爱普与美国铝业签订了战略合作协议。美铝为爱普提供国际领先的车身结构技术并共同研发超轻高强度客车车身材料。

    坚固:爱普品质,坚若磐石,爱普全铝车身采用美铝第三代全铆接车身技术。拥有更高的抗疲劳强度和紧固力,能够大幅增加车身强度,在车辆遭受外来撞击时,使用铆接技术连接的车身能承受更长时间和更剧烈的碰撞。骨架采用高铁专用高强度铝型材,蒙皮采用美铝超轻高强度铝合金板,车身采用美铝航空技术 HUCK紧固件,真正做到了“永不松动”。

安全:减小发动机负荷,提高汽车的加速性及有效载荷;使转向和过弯更加灵活、稳定;有效降低刹车距离;

耐腐蚀:铝材具有极强的耐腐蚀性能,使用寿命可达15年以上,适用于酸雨较多或暴雨集中的沿海地区。

    爱普全铝车身相比较钢结构车身,全铝车身总减少近1000kg左右的重量。

    节省能耗:降低油耗6%-8%;节省电能6%-9%。

    环保:周期内约减少25吨二氧化碳的排放,碳排放的减少可创造额外价值。

    铝材回收:铝材回收利用率可达95%,是节能减排,提高运输效率的首选金属材料。

    电池成本:车身减重10%,同样的续航里程减少8%电池采购成本。

    整个生命周期成本约下降8%。
 

Leading the lightweight era of China's automobile-- Aipu Vehicle (China) Co.,Ltd.

With the gradual depletion of oil resources, governments are more stringent with the emissions of automobile enterprises. Besides the use of hybrid, pure electric and other new energy sources, improving energy efficiency of traditional fuel vehicles or the application of lightweight technology is also a more direct and effective way to reduce emissions, save energy and protect environment.

As a lightweight material, aluminum alloy is widely applied in aerospace and transportation. Aluminum bus body,which used riveting and other joining technology to accomplish the overall frame structure, is generally only about 60% weight of the steel body. With the characteristics of high reliability, light weight, good strength and strong rigidity,the fuel economy and safety are largely improved compare to steel body. Body, as the heaviest part of a vehicle, can be achieved 100% aluminum by the current technology.

Next, let´s take a look at the technology and advantage of Aipu aluminum bus body.

Increasing the body strength, meanwhile reduce the body weight, it seems contradictory, but is the characteristic of Aipu vehicles that use aluminum alloy for bus body. 2015, AIPU and Alcoa signed a strategic cooperation agreement. Alcoa provides international leading technology of body structure design and develop ultra light high strength bus body material with Aipu.

Strong: Rock-solid quality, only from Aipu. Aipu uses the third generation riveted body structure. A higher anti fatigue strength and tightening force significantly increase the body strength. When the vehicle is subjected to external impact, the body which uses riveting technology for connection can withstand longer and more intense collision. It uses special high-strength aluminum sections which provided for high-speed rail for frames and ultra-high-strength aluminum bus plate for covers. The body is connected with Alcoa´s  "never loose" HUCK Fasteners.

Safety: Reduce engine load, improve the vehicle acceleration property and effective carrying capacity; the steering and cornering are more flexible and stable; effectively reduce the braking distance; aluminum alloy structure enlarges the passenger space.

Corrosion resistance: Aluminum is highly resistant to corrosion, thus its service life can up to 15 years and it is more suitable for acid rain or heavy rains in coastal areas

Compared with the steel body structure, using aluminum bus body will reduce nearly 1000kg of the total weight.

Save energy: it decreases 6%-8% fuel consumption and 6%-9% electric energy.

Environmental protection: the entire bus life cycle will reduce the emission of 25 tons of carbon dioxide, which can be exploited to extra value.

Aluminum recovery: 95% recovery rate makes it to be the top material to increase transport efficiency as well as saving energy.

Battery cost: body weight loss 10%; reduce 8% battery purchasing cost.
