The invention belongs to the technical field of vehicle manufacturing, and particularly relates to a power bogie which comprises a pair of frameworks and a traction device arranged between the two frameworks. The framework is connected with a sliding rail mechanism, the sliding rail mechanism is connected with a damping mechanism used for supporting the carriage, the traction device is connected with a fixing seat, and the fixing seat is connected with a steering shaft. A pair of sliding seats is symmetrically connected to the fixing seat in a sliding mode, the sliding seats are connected with a connecting frame, the two ends of the connecting frame are connected with the framework, and a driving mechanism used for driving the two sliding seats to slide towards the two sides is connected to the steering shaft; a telescopic arm is connected between the fixed seat and the framework; when the traction vehicle passes through a curve, the steering shaft rotates to drive the frameworks on the two sides to move towards the two sides, and the frameworks deviate transversely, so that the vehicle keeps sufficient stability during turning, the flexible performance of the bogie is improved, and the situation that the vehicle turns on one side is avoided.
本发明属于车辆制造技术领域,尤其是一种动力转向架,本发明包括一对构架以及设于两构架之间的牵引装置;构架上连接有滑轨机构,滑轨机构上连接有用于支撑车厢的减震机构,牵引装置上连接有固定座,固定座上连接有转向轴;固定座上对称滑动连接有一对滑座,滑座连接有连接架,连接架两端分别与构架连接,且转向轴上连接有用于带动两滑座向两侧滑动的驱动机构;且固定座与构架之间连接有伸缩臂;该牵引车辆在经过弯道时,转向轴转动带动两侧的构架向两侧移动,构架发生横向偏移,使得车辆在转弯时保持足够的稳定性,提高转向架的灵活性能,避免车辆侧翻的状况发生。
