当前我国商用车AMT自主研发及产业化过程中的主要技术难点

Main Technology Difficulties of Independent Research,Development and Industrialization Process of China Commercial Vehicles AMT at Present

随着高速公路的发展．运输市场对功率在300马力以上的卡车及特种专用汽车的需求越来越大。而目前配置这些重型汽车的变速箱多为手动，档位多、换档复杂．即使熟练的驾驶员也很难掌握最佳换档时机：进口的自动变速器价格又十分昂贵，用户很难接受。因而，实现电控机械式自动变速器（AMT）的自主研发和产业化．是当前我国重型商用车发展的重要选择与必然趋势。

With expressway development,transport market demand is growing for above 300Hp truck and special purpose vehicle.At present most heavy-duty trucks use manual transmission.Because of multi and complex shift,also skilled driver master shift in best time so difficult.The price of imported automatic transimission is expensive and user can not accept.So,achieving independent research,development and industrialization of electronical controlled mechanical automatic transimission(AMT) is important option and inevitable trend for nowaday China heavy-duty commercial vehicle development.
