The invention relates to the technical field of suspension type rail transit, in particular to a wheel track changing mechanism and a bogie, and aims to solve the problem of insufficient contact between walking wheels and a walking plate when a train runs on rails with different widths. The wheel track changing mechanism comprises a walking wheel, a sliding shaft, a power shaft and a shifting rod assembly. The traveling wheel is mounted at one end of the sliding shaft; one end, deviating from the traveling wheel, of the sliding shaft sleeves the power shaft; the sliding shaft can move in the axis direction of the power shaft and drive the walking wheels to move in the axis direction of the power shaft. The power shaft rotates around the axis of the power shaft to drive the sliding shaft to rotate so as to drive the walking wheels to rotate. According to the wheel track changing mechanism, the shifting rod assembly drives the sliding shaft to move in the axis direction of the power shaft so as to drive the walking wheels to move in the axis direction of the power shaft, so that the positions, perpendicular to the advancing direction, of the walking wheels are adjusted to adapt to changes of the width of the track, and insufficient contact between the walking wheels and the track is avoided.

    本发明涉及悬挂式轨道交通技术领域,尤其涉及一种变轮距机构及转向架,旨在解决列车在不同宽度轨道运行时行走轮与行走板接触不充分的问题。本发明提供的变轮距机构包括行走轮、滑动轴、动力轴和拨杆组件;行走轮安装于滑动轴的一端,滑动轴背离行走轮的一端套装于动力轴;滑动轴可沿动力轴的轴线方向移动并带动行走轮沿动力轴的轴线方向移动;动力轴绕自身轴线转动以带动滑动轴转动,进而带动行走轮转动。本发明提供的变轮距机构通过拨杆组件带动滑动轴沿动力轴的轴线方向移动以带动行走轮沿动力轴的轴线方向移动,从而调节行走轮在垂直于前进方向上的位置,以适应轨道宽度的变化,避免行走轮与轨道接触不充分。
