随着电控技术水平的不断提高,目前工程车辆传动系统正由传统的手动操纵向自动操纵方向发展。为对BF6M1015CP型电控柴油发动机、HD4070PR型电控液力自动变速器进行实车试验,通过匹配电控柴油机以及自动变速器的北方奔驰2627K型工程自卸车进行路面行驶试验,测试车辆的自动换挡性能,研究换挡过程特性,通过研究、掌握国外先进自动变速技术,为国内研究开发工程车辆自动变速技术提供参考。
With the continuous improvement of the technology of electric control, the transmission system of engineering vehicles is developing from the traditional manual control to automatic control. For the BF6M1015CP-type diesel engine, HD4070PR-type electro-hydraulic automatic transmission for real car test, through the matching diesel engine and automatic transmission north of Mercedes-Benz 2627K-type dump truck road test to test the vehicle’s automatic shift performance , Study the shift process characteristics, through research, master advanced automatic transmission technology abroad, for the domestic research and development of engineering vehicles automatic transmission technology to provide a reference.
