The embodiment of the invention provides a multi-axle bogie and a rail vehicle. A framework of the multi-axle bogie comprises a cross beam, side beams and a center plate beam. Wherein a plurality of wheel pairs are mounted at the bottoms of the side beams, an axle box device is mounted on the outer side of each wheel pair, and the axle box devices are respectively connected with axles of the wheel pairs and the bottoms of the side beams; side bearing devices are installed on the tops of the middles of the side beams, and the tops of the side bearing devices are used for making contact with a vehicle body and reducing friction force of relative rotation between the framework and the vehicle body. A center plate device is installed on the center plate beam, and the top of the center plate device makes contact with the vehicle body and is used for adapting to relative rotation between the vehicle body and the framework. The bogie can adapt to rotary motion between a vehicle body and the bogie, is favorable for improving the curve passing performance of the vehicle, and is suitable for the technical field of bogies of large-scale rail engineering vehicles.

    本申请实施例提供一种多轴转向架及轨道车辆,多轴转向架的构架包括:横梁、侧梁、心盘梁;其中,侧梁底部安装有多个轮对,每个轮对的外侧均安装有轴箱装置,轴箱装置分别与轮对的轮轴和侧梁的底部连接;侧梁的中间顶部安装有旁承装置,旁承装置的顶部用于与车体接触,用于减小构架与车体之间相对转动的摩擦力;心盘梁上安装有心盘装置,心盘装置的顶部与车体接触,用于适应车体与构架之间的相对转动。该转向架能够适应车体与转向架之间的回转运动,有利于提高车辆通过曲线的性能,适用于大型轨道工程车转向架的技术领域。
