The invention discloses a straddle type monorail unpowered bogie. The bogie structurally comprises a side frame, a swing bolster assembly and a wheel set assembly. The swing bolster assembly is provided with an elastic bearing and a hydraulic spring group. The wheel set assembly is provided with hubs and a rotating shaft, and the hubs are connected to the two ends of the rotating shaft. The beneficial effects of the invention are that: a hydraulic cylinder drives a screw rod to push a cleaning head to descend on a damping spring, so that a cleaning groove in the cleaning head is driven to be embedded into the damping spring, a brush in the cleaning groove is driven to clean soil condensed on the damping spring, the damping spring is kept clean, and the situation in which the soil influences work of the damping spring is avoided; and the hydraulic cylinder drives the screw rod to ascend, so that the cleaning head is driven to conduct reverse cleaning on the damping spring, secondary cleaning is completed, the cleaning strength of the cleaning head can be enhanced through secondary cleaning, meanwhile, the cleaning head is restored to the original position, and the situation in whichthe cleaning head clamps the damping spring and work of the damping spring is affected is prevented.

    本发明公开了一种跨座式单轨无动力转向架,其结构包括侧架、摇枕组成、轮对组成,摇枕组成设有弹性轴承、液压弹簧组,轮对组成设有轮毂、转轴,轮毂连接于转轴两端,本发明的有益效果是:通过液压缸带动螺旋杆推动清理头在减震弹簧上进行下降,从而带动清理头上的清理槽嵌入减震弹簧,带动清理槽内部的毛刷对减震弹簧上凝结的泥土进行清理,从而使得减震弹簧保持干净,避免泥土影响减震弹簧的工作;通过液压缸带动螺旋杆进行上升,从而带动清理头在减震弹簧上进行反向清理,从而完成二次清理,通过二次清理能够加强清理头的清理力度,同时将清理头恢复原位,防止清理头卡住减震弹簧,影响减震弹簧的工作。
