The invention relates to a walking device of a rail car. The walking device comprises a power walking part, a driven walking part and a suspension beam. The suspension beam and the power walking partare connected by a slewing bearing, the suspension beam and the driven walking part are connected by the slewing bearing, and the driven walking part can oscillate in a walking direction of the walking device of the rail car relative to the power walking part. The walking device comprises the three parts: the power walking part, the driven walking part and the suspension beam. The suspension beamis mounted on the power walking part and the driven walking part by the slewing bearing. According to the structure, the walking device of the rail car is flexible to turn and good in curve trafficability characteristic. By adopting frames with two double shafts, one shaft is provided with one wheel. As two frames are arranged, that is, the power walking part frame and the driven walking part frame, the two frames are connected together by using the suspension beam. The slewing bearing is used at a connection of the suspension beam and the frame. When a vehicle passes a turnout and a curve ofa box type rail, the walking device is more flexible to turn and a phenomenon of stagnation or suspension of a single wheel is avoided.
一种轨道车走行装置,包括:动力走行部、从动走行部以及悬挂梁,悬挂梁与动力走行部采用回转支承连接,悬挂梁与从动走行部采用回转支承连接,从动走行部可相对于动力走行部在轨道车走行装置的走行方向上摆动。本发明包括动力走行部、从动走行部以及悬挂梁三个部分,悬挂梁通过回转支承安装到动力走行部与从动走行部上,该结构可使得轨道车走行装置转向灵活,弯道通过性好。本发明采用两个双轴的车架,一个轴安装一个车轮。车架设置有两个,即动力走行部车架以及从动走行部车架,两个车架之间采用悬挂梁连接到一起,悬挂梁与车架的连接处采用回转支承,在车辆通过箱型轨道道岔和弯道时,其转向更加灵活,不会存在卡滞或者单轮悬空的现象。
