The invention relates to an incomplete load power shaft for improving traction force of a rack rail train, which comprises a power shaft framework, one end of the power shaft framework can be connected to a bogie framework of a bogie through a multi-connecting-rod traction mechanism, and the other end of the power shaft framework can be connected to the bottom of a rack rail train body through a secondary spring. A single-shaft rack rail driving device is arranged on the power shaft framework, the single-shaft rack rail driving device can provide traction force on a line rack rail section, and the multi-connecting-rod traction mechanism enables the power shaft framework to only horizontally move relative to the bogie framework in the vertical direction. The power shaft is connected to one side of the bogie, traction force is generated through the action of the power shaft and the ground rack rail on a large-gradient road section, the traction force is transmitted to the bogie through the multi-connecting-rod traction mechanism, and therefore the train is dragged to run on a larger gradient, and the power shaft does not participate in driving and only serves as a follow-up component on a small-gradient and wheel-rail section. Meanwhile, the nodding motion of the power shaft is effectively restrained through the multi-connecting-rod traction mechanism.

    本发明关于一种提升齿轨列车牵引力的非完全荷载动力轴,包括动力轴构架,动力轴构架的一端通过多连杆牵引机构能够连接于转向架的转向架构架,动力轴构架的另一端通过二系弹簧能够连接于齿轨列车车体底部,动力轴构架上设有单轴齿轨驱动装置,单轴齿轨驱动装置能够在线路齿轨段提供牵引力,多连杆牵引机构使动力轴构架在垂直方向仅能够相对转向架构架平动。本发明的动力轴连接于转向架的一侧,在大坡度路段,动力轴与地面齿轨作用产生牵引力,通过多连杆牵引机构将牵引力传递到转向架,从而牵引列车在更大坡度上运行,在小坡度及轮轨地段,动力轴不参与驱动,仅作为随动部件,同时多连杆牵引机构有效抑制了动力轴自身的点头运动。
