参见图1-图4，一种电机、车架和后叉的同轴固定结构，包括电机1、车架侧板件、后叉2及边盖3，而车架侧板件又包括车架左侧板41和车架右侧板42，车架左侧板41和车架右侧板42又对应有各自的边盖3，后叉2前端具有两个连接部位。
本实施例中，以电机1为中间部位，车架左侧板41、后叉2前端一侧的连接部位21及对应的边盖3位于电机1左侧；车架右侧板42、后叉2前端另一侧的连接部位22及对应的边盖3位于电机1右侧。
在电机1左侧，车架左侧板41与后叉2前端一侧的连接部位21通过一固定销5使两者相连，车架左侧板41与后叉2前端一侧的连接部位21两者的铰接轴线与电机1转子中心线相重合。
同时，可在后叉2前端一侧的连接部位21与固定销5之间设置轴承6，即固定销5至少部分部位穿设与轴承6处。
而车架左侧板41与电机1之间通过紧固件固定连接，固定销5由该侧的边盖3定位，边盖3固定于车架左侧板41上，边盖3固定时又将后叉2前端一侧的连接部位21定位，如此，将电机1左侧的各部件固定牢靠。
进一步的，在该处的边盖3与固定销5之间还可设置有卡簧7。
在电机1右侧亦是如此，即车架右侧板42与后叉2前端另一侧的连接部位22通过一固定销5使两者相连，同时，可在后叉2前端另一侧的连接部位22与固定销5之间设置轴承6，即固定销5至少部分部位穿设于该轴承6处。
而车架右侧板42与电机1之间通过紧固件固定连接，固定销5由该侧的边盖3定位，边盖3固定于车架右侧板42上，边盖3固定时又将后叉2前端另一侧的连接部位22定位，如此，将电机1右侧的各部件固定牢靠。
进一步的，在该处的边盖3与固定销5之间还可设置有卡簧7。
本实施例中，所述车架左侧板41及所述车架右侧板42上分别设置有若干安装位8，通过设置于对应安装位8上的紧固件将其与所述电机1固定连接，可进一步的设计为：所述车架左侧板41上的安装位及所述车架右侧板42上的安装位均一一对应，且对应的安装位同轴设置。
为更为体现装置的整体性及安装的快捷性，可将位于所述电机1两侧的车架左侧板41、车架右侧板42及所有边盖3均通过同组紧固件与电机1固定连接。
本实施例中，所述电机1输出轴上设置有传动件11，所述传动件11与传动皮带12传动连接，用于动力的输出。
