The embodiment of the invention provides a bogie and a rail engineering vehicle. The bogie comprises two wheel sets, a framework and two power devices, wherein the two wheel sets are oppositely arranged, and each wheel set comprises an axle and two wheels fixed to the two sides of the axle; each wheel set is provided with two axle boxes, and the two axle boxes are arranged on the axle and locatedbetween the two wheels; the framework comprises two side beams arranged oppositely and a cross beam connected with the two side beams, and the side beams are perpendicular to the axle and connected tothe axle boxes; the two power devices are respectively used for driving the two wheel sets to move, and are symmetrically arranged relative to the center of the bogie; the power device comprises a traction motor, a transmission mechanism and a gear box, the traction motor is arranged on the framework and connected with aninput end of the gear box through the transmission mechanism, and an outputend of the gear box is connected with the axle. The embodiment of the invention is beneficial to reducing the size of the bogie, so that the bogie is enabled to be suitable for running on a rail witha smaller limit.

    本申请实施例中提供了一种转向架及轨道工程车辆,转向架包括两个轮对、构架和两个动力装置,两个轮对相对设置,轮对包括车轴和固定在车轴两侧的两个车轮;每一个轮对上设有两个轴箱,两个轴箱均设置在车轴上且位于两个车轮之间;构架包括相对设置的两个侧梁以及连接两个侧梁的横梁,侧梁垂直于车轴且连接在轴箱上;两个动力装置分别用于驱动两个轮对运动,两个动力装置相对于转向架的中心对称设置;动力装置包括牵引电机、传动机构和齿轮箱,牵引电机设置在构架上,牵引电机通过传动机构连接齿轮箱的输入端,齿轮箱的输出端连接车轴。本申请实施例有利于缩小转向架的尺寸,从而使转向架适合于运行在较小限界的轨道上。
