The invention belongs to the technical field of railway traffic, and particularly relates to a hybrid power transmission power pack applied to a railway track car and an operation car. The technical problems that existing internal combustion engine transmission is heavy in tail gas pollution, and electric driving is limited by the electric quantity of a battery and the cost are solved. A hybrid power transmission power pack applied to a railway track car and an operation car comprises an installation frame, and a diesel engine and a hybrid transmission device are sequentially installed in the installation frame from the non-output end to the output end. The hybrid transmission device comprises a clutch, a traction motor, a reversing box and an automatic gearbox which are sequentially mounted from a non-output end to an output end, and an output interface of the automatic gearbox is used for outputting power; the diesel engine is connected with the traction motor through the clutch, the traction motor is connected with the reversing box through a spline shaft, and the reversing box is connected with the automatic gearbox through a spline shaft. The reversing box of the power pack is arranged in the middle, the torque borne by the reversing box can be reduced, the size of the reversing box is reduced, and the space utilization rate is increased.

    本发明属于铁路交通技术领域,具体是涉及一种应用于铁路轨道车、作业车用混合动力传动动力包。解决了目前内燃机传动存在尾气污染较重、而电动驱动又受限于电池电量以及成本的技术问题。一种应用于铁路轨道车、作业车用混合动力传动动力包,包括安装框架,安装框架内由非输出端向输出端依次安装有柴油机和混合传动装置;所述混合传动装置包括由非输出端向输出端依次安装的离合器、牵引电机、换向箱、自动变速箱,自动变速箱的输出接口进行动力输出;所述柴油机通过离合器与牵引电机连接,牵引电机与换向箱、换向箱与自动变速箱均采用花键轴连接。本动力包的换向箱采用中置布置,可减小换向箱承受的扭矩,减小换向箱的体积,提高空间利用率。
