节能减排法规的日渐趋严,混合动力汽车的逐渐普及化的趋势,推动了汽车传动装置的变革和技术进步。北美自由贸易区(美国、加拿大、墨西哥)的生产预测具有一定的代表性。传动装置的种类由于目前在北美的大多数制造基地生产自动变速器,因此至少在近期或中期,各种档位和型式的自动档变速器会占据大多数的市场份额。鉴于汽车制造商会继续在节能减排下功夫,所以自动档可以通过高效率的电控系统提高整车的性能,并且会相应减少驾驶员对传动 Energy-saving emission reduction regulations increasingly stringent, hybrid vehicles gradually universal trend, and promote the transformation of automobile transmission and technological progress. North American Free Trade Area (the United States, Canada, Mexico) production forecast has a certain representation. Types of Gearing As automatic transmissions are currently manufactured in most manufacturing sites in North America, automatic transmissions of various gears and types will account for the majority of the market, at least in the near and medium term. In view of the fact that automakers will continue their efforts in energy saving and emission reduction, the automatic transmission can improve the performance of the vehicle through an efficient electronic control system and reduce the driver’s effort on the transmission
