The single-axle bogie comprises a framework, a left radial oil cylinder, a right radial oil cylinder, a left turning supporting wheel set and a right turning supporting wheel set, the left radial oil cylinder and the right radial oil cylinder are symmetrically arranged between the framework and a vehicle body, and the left turning supporting wheel set and the right turning supporting wheel set are arranged on the framework. All the left buffering oil cylinders of the left turning supporting wheel set are connected with the left radial oil cylinder, and all the right buffering oil cylinders of the right turning supporting wheel set are connected with the right radial oil cylinder. By means of the left buffering oil cylinder and the right buffering oil cylinder, one of the left radial oil cylinder and the right radial oil cylinder is controlled to automatically stretch out and the other one of the left radial oil cylinder and the right radial oil cylinder is controlled to automatically retract in a minimum-energy-consumption mode, so that a vehicle body is stably supported to steer, and a side slip angle and a side deviation force generated when a framework turns are reduced; and meanwhile, the pre-tightening force of the left-turning supporting wheel set and the pre-tightening force of the right-turning supporting wheel set are adjusted, so that the pre-tightening force is kept stable within a certain range, and the transverse stability of the vehicle body during turning is effectively improved.
本发明公开一种跨座式单轨车辆及其单轴转向架,其中,单轴转向架包括构架、对称设于构架与车体之间的左径向油缸和右径向油缸及分别设于构架的左转支撑轮组和右转支撑轮组;左转支撑轮组的全部左缓冲油缸均与左径向油缸相连,右转支撑轮组的全部右缓冲油缸均与右径向油缸相连。本发明借助左缓冲油缸和右缓冲油缸,以最小能耗的方式控制左径向油缸和右径向油缸二者中的一者自动伸出且另一者自动回缩,以稳定支撑车体转向,减小构架转弯时产生的侧偏角和侧偏力,并同时调整左转支撑轮组和右转支撑轮组的预紧力,使预紧力在一定范围内维持稳定,从而有效改善车体转弯时的横向平稳性。
