The invention relates to the technical field of rail transit, and discloses an urban rail transit vehicle bogie which is characterized in that the axis of a rotating frame, the axis of a rotating groove and the axis of a rotating hole are located on the same center line, so that a rotating device can rotate by taking the axis of the rotating hole as the central line. And meanwhile, guide rotatingwheels are fixedly mounted at the positions, located on the two sides, of the two ends of the rotating frame. When wheel axles rotate, a brake disc deflects, is in contact with the guide rotating wheels and pushes the guide rotating wheels to enable the rotating device to rotate; therefore, a trapezoidal groove can face the surface of the brake disc all the time; therefore, the contact surface ofan internal brake device and the brake disc can be always kept parallel to the surface of the brake disc when the brake disc deflects; the braking effect is still not reduced after the train is driveninto a curve, and the problem that the braking performance is reduced due to the fact that the wheel axles deflect after the train is driven into the curve and the brake disc and a brake block are not in a parallel posture any more is solved.

    本发明涉及轨道交通技术领域,且公开了一种城市轨道交通车辆转向架,通过旋转架的轴线、转动槽的轴线和转动孔的轴线位于同一条中心线上。使得旋转装置可以转动孔的轴线为中心线进行旋转,同时通过旋转架两端位于两侧的位置上固定安装有导向转轮。当轮轴进行旋转时,使刹车盘发生偏转并与导向转轮发生接触并推动导向转轮使得旋转装置发生转动,从而使梯形槽能够一直朝向刹车盘的表面,从而使内部的刹车装置与刹车盘的接触面能够在刹车盘发生偏转时能够一直保持与刹车盘表面处于平行的位置上,使得火车驶入弯道后刹车的效果依然不会减少,避免了因火车驶入弯道后轮轴发生偏转而使刹车盘与刹车块之间不再处于平行的姿态而导致刹车性能下降的问题。
