The invention relates to the technical field of straddle type rail transit, in particular to a straddle type monorail train power frame and a rail system.According to the scheme, the power frame is suitable for running on a large-gradient line, a driving gear and a gear transmission mechanism are connected through a flexible connecting pair, the flexible connecting pair only transmits torque, and therefore the driving gear and the gear transmission mechanism are connected through the flexible connecting pair; the driving gear and the gear transmission mechanism can be allowed to be transversely and horizontally staggered; when the meshing state of the driving gear and the rack is not good, the driving gear tends to generate tiny plane dislocation relative to the gear transmission mechanism under the action of the rack meshing force, and the driving gear transmits the longitudinal meshing force to the front pull rod, the rear pull rod and the surrounding buffer device through the swing limiting device. The transverse position of the driving gear is limited through the buffering device, the effect of buffering vibration impact is achieved, the driving gear and the rack can be prevented from being disengaged, and therefore the driving gear can automatically adapt to the meshing state of the driving gear and the rack, and better curve passing performance is obtained.
本发明涉及跨座式轨道交通技术领域,具体涉及一种跨座式单轨列车动力架及轨道系统,本方案中的动力架适用于在大坡度线路上行驶,该动力架通过将驱动齿轮和齿轮传动机构通过柔性连接副进行连接,该副仅传递扭矩,并能够允许驱动齿轮与齿轮传动机构之间发生横向水平错位;当驱动齿轮和齿条啮合状态不佳时,驱动齿轮在齿条啮合力作用下相对齿轮传动机构趋向发生细微平面错动,驱动齿轮将纵向的啮合力通过摆动限位装置传递给前后拉杆和周围的缓冲装置,通过缓冲装置限制驱动齿轮的横向位置且具有缓冲振动冲击的效果,能够避免驱动齿轮与齿条脱离啮合,从而使驱动齿轮能够自动适应调节与齿条的啮合状态,从而获得更好的曲线通过性能。
