The embodiment of the invention provides a bogie and a rail engineering vehicle, and relates to the technology of large railway maintenance machinery. The technology is used for solving the problem that in the related technology, the gravity center of a rail engineering vehicle is prone to shifting, so that the suspension deformation difference of the two sides of the rail engineering vehicle is caused, and the vehicle inclines or overturns. The bogie is used for the rail engineering vehicle, and comprises a framework equipped with two opposite side beams; wheel pairs, that are mounted on the side beams of the framework through axle boxes; a jacking shaft oil cylinder which is mounted on a first mounting seat arranged on the side beam and is used for connecting the framework with an axle box; a truck jacking oil cylinder which is mounted on a second mounting seat arranged on the side beam and is used for connecting the framework with a truck body; and a control device which is used for controlling stretching and retracting of the jacking shaft oil cylinder and the car jacking oil cylinder.

    本申请实施例提供一种转向架及轨道工程车,涉及铁路大型养路机械技术,用于克服相关技术中轨道工程车重心易偏移导致轨道工程车两侧的悬挂变形量差异进而造成车辆倾斜或倾覆的问题。所述转向架,用于轨道工程车辆,包括:构架,具有两个相对设置的侧梁;轮对,通过轴箱安装至所述构架的侧梁;顶轴油缸,安装至设于所述侧梁的第一安装座,用于将所述构架与轴箱连接;顶车油缸,安装至设于所述侧梁的第二安装座,用于将所述构架与车体连接;控制装置,用于控制所述顶轴油缸及顶车油缸的伸缩。
