摘　　要：根据动力形式的不同,当前煤矿无轨辅助运输车辆动力传动系统主要采用防爆柴驱传动技术或防爆电驱传动技术。通过分析两种动力系统的技术现状及其典型传动系统的布置形式和结构特点,指出了防爆柴驱车型因防爆柴油机尾气污染问题而发展受限,而防爆电控燃油喷射技术及防爆电液控制技术在该类车型动力传动系统中的应用可有效降低系统排放、提高传动效率,是实现防爆柴驱车辆节能减排的关键技术。但防爆电驱车型受制于续驶里程不足,维护使用成本过高等问题,短期内难以规模化应用。为此,隔爆型永磁同步电动机及分布式电驱动技术因具有高效节能、易于布置等特点,是该类车型动力传动技术的发展趋势。According to the different power forms,at present,the power transmission system of trackless auxiliary transport vehicles in coal mine mainly adopts explosion-proof diesel drive technology or explosion-proof electric drive technology.Based on the analysis of the technical status of the two power systems and the layout and structural characteristics of their typical transmission systems,it has been pointed out that the development of explosion-proof diesel engine models was limited due to the exhaust pollution of explosion-proof diesel engine,and the application of explosion-proof electronic fuel injection technology and explosion-proof electrohydraulic control technology in the power transmission system of these vehicles can effectively reduce the system emissions and improve the transmission efficiency,which is to achieve key technologies for energy conservation and emission reduction of explosion-proof diesel driven vehicles.However,the explosion-proof electric drive model is limited by the lack of driving mileage,high maintenance and use costs,and it is difficult to be applied in a large scale in a short period of time.For this reason,flameproof permanent magnet synchronous motor and distributed electric drive technology have the characteristics of high efficiency,energy saving and easy layout,which is the development trend of power transmission technology of this type of vehicle.
