The invention provides a plug-in hybrid power heavy-duty tractor chassis which is provided with a front axle, a middle axle and a drive axle which are sequentially arranged on a tractor frame from front to back. An engine is arranged in the center of the front axle; the rear end of the engine is connected with the drive axle input end sequentially through a motor, a gearbox, a middle axle transmission shaft and a drive axle middle transmission shaft. High-voltage battery devices are arranged at the upper end of the gearbox and on the upper wing surfaces of the left and right beams of the frame on the rear side of the cab, and are connected with a motor circuit. The device has a pure electric driving function and meets the requirement of hanging green boards; the energy utilization rate and the mechanical efficiency are effectively improved; the problem that the endurance mileage is short due to battery offset and limited battery capacity of an existing hybrid electric vehicle is solved. The chassis is simple in structure, reasonable in chassis part arrangement, high in space utilization rate, convenient to assemble, capable of achieving serialization and modularization and suitable for popularization, and can be directly refitted on a conventional vehicle to achieve the battery replacement function.

    提供一种插电式混合动力重型牵引车底盘,具有在车架上由前至后依次设置的前桥、中桥和驱动桥;前桥上部中心位置设有发动机;发动机后端依次经电机、变速箱、中桥传动轴、驱动桥中间传动轴与驱动桥输入端相连;变速箱上端以及驾驶室后侧车架的左右梁上翼面设有高压电池装置,且高压电池装置与电机电路相连。本发明具备纯电行驶功能,满足挂绿牌要求;有效提升能量利用率,机械效率;解决现有混动汽车电池偏置以及电池容量有限导致的续航里程短的问题;结构简单,底盘零部件布置合理,空间利用率高,可直接在常规车上改装和实现换电功能,便于装配,能实现系列化、模块化,适合推广。
