摘　　要：为解决传统检修车在高速铁路长大坡道线路区段上坡动力不足、下坡制动闸瓦温度高的问题,文章通过增大柴油机组装机功率并结合电传动牵引系统良好的牵引和电制动性能,设计了一套适用于长大坡道的工程车电传动牵引系统,其采用两车固定重联运行方式,车辆功率大、制动能力强。相比目前采用的HXN5型货运机车,所设计的电传动工程车具有自重轻、惯性小、制动距离短等特点,极大地降低了检修过程对钢轨造成损伤的可能性;相比HXN5型货运机车只能向前牵引、不能向后退行,新型电传动工程车可向前、向后行驶,极大地减少了时间浪费,提高了维护效率。整车型式试验及西成高铁实际试验结果显示,采用该牵引系统的电传动轨道工程车单机上坡时速最高可达107 km,下坡时施加电阻制动后可在100 km/h速度内稳定运行,且电传动牵引系统稳定、可靠。To solve the problem of maintaining equipment on high-speed railway lines with long ramp,this paper designs an electric drive traction system for engineering vehicles suitable for long ramp, by increasing the power of the diesel engine and combining the good traction and braking performance of the electric drive.The traction system can adopt a two-vehicle fixed couple operation mode, and the vehicle has high power and strong braking ability. It effectively solves the problems of insufficient power for uphill and high temperature of downhill brake shoes for traditional maintenance vehicles running on long ramp. Compared with HXN5 freight locomotive, the designed electric drive engineering vehicle has the characteristics of light weight, small inertia and short braking distance, which greatly reduces the possibility of damage to the rail during maintenance. Compared with HXN5 freight locomotive, which can only be pulled forward and cannot be driven backward, the new electric drive engineering vehicle can travel forward and backward, which greatly reduces time waste and improves maintenance efficiency.Type test result of whole vehicle and actual test result of Xicheng high speed railway show that the electric drive rail engineering vehicle using this traction system can reach a maximum speed of 107 km/h uphill, and can run stably within 100 km/h after applying resistance braking as the vehicle being downhill, and the electric drive traction system is stable and reliable.
