The new E-drive Axle is suitable for refrigerator semi-trailers, semi-trailers on rough roads, pure electric trucks and television broadcast trucks.
SAF-Holland China at Automechanika Shanghai 2018
SAF-Holland China participated in the Automechanika Shanghai 2018, which was held from 28th November to 1st December at the National Exhibition and Convention Center, Shanghai. Taking centre-stage at the company’s booth was the E-drive Axle.
According to E-drive Engineer Yan Zijiang, the E-drive Axle made its debut at the IAA Commercial Vehicle show in Hannover last year. This was a new product developed by SAF-Holland China especially for the Chinese logistics market.
“We started developing this product in February last year and completed it in August the same year. There are similar products in the market but they are mostly high-end products from the European countries that sell at far higher prices. In addition, they are not so suitable for our local market.”
With a load capacity of 13 tonnes, the new E-drive Axle is said to be suitable for refrigerator semi- trailers, semi-trailers on rough roads such as the steep inclines in mountainous areas, pure electric trucks and television broadcast trucks.
“The E-drive module recovers the energy during braking or driving downhill and transforms the motion energy of the vehicle into electrical energy. This energy is stored in a lithium-ion battery and used subsequently for auxiliary units in the semi-trailer, such as cooling systems, heaters, lighting, tail lifts and others. The stored energy could also be the main drive support for the semi-trailer on difficult terrain, including sloping or muddy roads, ensuring safety and driveability. The integrated E-drive design combines the E-drive module and the axle is maintenance free; thus, there is no extra maintenance and servicing cost. The truck could be driven by multiple axles instead of the engine, achieving full-electric drive,” he explained.
He also revealed that the company was in the process of applying for the patent right for this new E-drive Axle.
中国赛夫华兰德携电驱动车轴
亮相2018年Automechanika Shanghai 展
中国赛夫华兰德（SAF-Holland）参与从11月28日至12月1日在上海国家会展中心盛大举行的2018年Automechanika Shanghai 展。 电驱动车轴是该公司重点展出的产品。
据电驱动车轴工程师杨子江表示，电驱动车轴第一次展出是在去年于汉诺威举行的IAA商用车展。这是中国赛夫华兰德特别为中国物流市场开发的产品。
“我们在去年2月时进行开发，并在同年8月完成这个产品。中国国内有许多类似的产品，不过大部分都是来自欧洲国家的高档货，价格都相当高。再加上，它们不太适合国内市场。”
该电驱动车轴具有13吨的承载力，适合冷藏半挂车、行驶路况恶劣如山高坡陡的半挂车、纯电动卡车及电视台转播车使用。
“电驱动车轴的电机在刹车与下坡工况下，用来回收能量。该能量将储存在锂离子电池中，并可用于半挂车的辅助单位如制冷、制热、照明、升降上。该储存的能量也可在爬坡、泥泞路况等需要大力矩的工况下为半挂车提供额外的驱动力，增加车辆的通过性和安全性。电驱模块与车桥集成一体且免维护，不增加车桥的额外维护和保养成本。多桥联装可以独立驱动卡车，从而取代引擎实现卡车纯电动化。”他解释。
他也透露，该公司正在为此新的电驱动车轴申请专利。
