在本实施例中，发电机3包括电机转轴301、前轴承302、后轴承303、前端盖304、后端盖305、电机转子319和电机定子320，电机转轴301前端设有与行车发动机动力输出轴连接的连接部6，电机转轴301后端设有动力传动和分离机构。本发明的发电机3能直接利用车用的行车发动机的动力进行发电，电机转轴301能与行车发动机的曲轴同轴连接并将动力由电机转轴301传递到车辆的传动机构；电机转子319磁路为四极，电机定子320满足电机转子319在转速为1500rpm时，电机发出50Hz380V的交流电，可以广泛取代传统移动发电车车厢内的移动发电系统，从而不需要移动发电车车厢中设置动力系统，使整个移动发电车只有一套动力系统，节约了成本，大大减少了发电系统在移动发电车车厢中的占用空间。
在本实施例中，动力传动和分离机构包括在电机转轴301后端同轴安装的飞轮307和在飞轮307的端面上同轴安装的离合器308，离合器308包括固定设置在飞轮307的端面上的压盘311和设置在飞轮307与压盘311之间的从动盘310，从动盘310的轴孔上设有内花键318，飞轮307可以更加稳定有效地将动力传递出去，防止转速出现波动，离合器308可以平稳的将飞轮的动力传递到传递部件，并能迅速彻底的切断动力输出，使发电机3具有切断或传递行车发动机动力的功能；电机转轴301后端同轴安装有一输出法兰309，输出法兰309与电机转轴301通过花键连接，飞轮307通过螺栓与输出法兰309连接，飞轮307通过输出法兰309与电机转轴301连接，使飞轮307牢固安装在电机转轴301的后端，使动力传递更加稳定。
在本实施例中，电机转轴301上的前轴承302和后轴承303均为圆锥滚子轴承，在电机转轴301后端的飞轮307受到离合器308的压盘311挤压时，电机转轴301上的前、后圆锥滚子轴承能够抵消电机转轴301所受到的轴向推力而不易损坏，使发电机3运行更加稳定，发电机3使用寿命增长。

在本实施例中，前轴承302、后轴承303分别设有润滑结构，前轴承302的润滑结构是由前轴承302、前端盖304和电机转轴301围成的前润滑油腔体312，在前端盖304上设有润滑油注入/流出前润滑油腔体312的进油口/出油口；后轴承303的润滑结构是由后轴承303、后端盖305和电机转轴301围成的后润滑油腔体313，在后端盖305上设有润滑油注入/流出后润滑油腔体313的进油口/出油口。润滑油前端盖304、后端盖上的进油口进入前润滑油腔体312、后润滑油腔体313对电机转轴301上的两轴承进行冷却、润滑，再通过出油口流出，防止前轴承302、后轴承303因高速、长时间旋转而发热、磨损，增加轴承的使用寿命，保证发电机3运转的稳定性，保证发电机3输出固定频率电压的稳定性。
在本实施例中，在前端盖304与电机转轴301之间的前润滑油腔体312和后润滑油腔体313进行密封的密封件，密封件为：在前端盖304两端的孔壁与电机转轴301之间的空隙设有封闭前润滑油腔体 312的第一油封314、第二油封315，在后端盖305两端的孔壁与电机转轴301之间的间隙设有封闭后润滑油腔体313的第三油封316、第四油封317。通过第一油封314、第二油封315、第三油封316和第四油封317的密封作用，有效地防止润滑油渗漏，保证电机的正常使用，延长电机使用寿命，保持电机的整洁。
在本实施例中，行车发动机1设有可为空压机102提供润滑油的发动机润滑系统，用于润滑行车发动机1本体的活塞、连杆、曲轴轴瓦等，以及为安装在行车发动机1上的空压机102提供润滑油，在发动机润滑系统上连接有为发电机3的轴承提供润滑油的发电机3润滑机构。通过发电机3润滑机构对发电机3的转轴上的轴承进行冷却、润滑，防止发电机3的转轴跟随行车发动机1做高速长时间转动时，轴承会发热、磨损，增加发电机3的使用寿命，减小噪音，使行车发动机1和发电机3运行更加平稳；ECU模块4可以根据需要控制行车发动机1的转速，通过电气控制得到精确的转速，满足使用要求，反应速度快；行车发动机1在发电模式时，ECU模块4可以控制其转速保持在1500rpm，保证发电机3产生稳定频率的电压。
在本实施例中，发动机润滑系统包括油底壳103、连接油底壳103的机油泵104、连接机油泵104出口与空压机102进油口的供油管105以及连接空压机102出油口与油底壳103进口的回油管106，油底壳103、机油泵104和空压机102安装在行车发动机1上；发电机3润滑机构包括将供油管105与前润滑油腔体312及后润滑油腔体313的进油口相连通的进油管107，还包括将前润滑油腔体312及后润滑油腔体313的出油口与回油管106相连通的出油管108；供油管105设置有连接进油管107的第一三通109，回油管106上设置有连接出油管108的第二三通101。在发动机润滑系统的供油管105设置支管为 发电机3的前轴承302、后轴承303提供润滑油，直接在空压机102的进油口处取润滑油对发电机3的轴承进行冷却、润滑，与行车发动机1、空压机102共用机油泵104和润滑储存箱，不需额外设置油箱和升压机构，大大节约成本，减少空间占用，方便油管的布置，安装制造方便；发电机3润滑机构与发动机润滑系统同时运转，能及时的对发电机3进行润滑。
在本实施例中，发电机3上设有对发电机3产生的电流进行处理的稳压装置8和控制发电机3开始和停止发电的触发开关10，所述的触发开关10与ECU模块4相连接。在变速箱5空档状态下，可以操作触发开关10使发电机3进入发电模式，ECU模块2根据触发开关12的状态控制行车发动机1的转速，使行车发动机1转速保持在1500rpm，保证发电机3产生380v50Hz的电流，稳压装置8对发电机3产生的交流电进行处理，再输出到用电设备9。
在本实施例中，传动机构包括与离合器308相连接的变速箱5以及将动力依次传递到车轮2的传动轴6和后桥7，变速箱5的输入轴与发电机3的从动盘310通过花键连接。在移动发电车行车过程中，电机转子319跟随行车发动机1的曲轴同步旋转，触发开关10断开，发电机3处于空转状态，不进行发电，行车发动机1的动力经发电机3传递到飞轮307，最经过安装在飞轮307上的离合器308传递到变速箱5的动力输入轴，从而将动力经传动轴6、后桥7至车轮2，保证移动发电车的动力系统能满足行车需求。
