The invention provides a three-axle bogie for a rail engineering tractor, a frame is composed of two side beams, two middle beams and an end beam, and a plurality of sets of spring sliding block type supporting devices used for supporting a tractor body are symmetrically arranged on the two side beams; the spring sliding block type supporting device, a side baffle arranged at the bottom of the side beam and the traction rod device form a suspension elastic supporting structure for a vehicle body. The axle gear boxes on the axles in every two adjacent wheel set assemblies are connected through a transmission shaft, and synchronous rotation of the three axle gear boxes driven by the power driving system is achieved. By improving the supporting structure for supporting the tractor body, on the premise that the low cost and safety performance of the engineering tractor are guaranteed, the engineering tractor has the advantages of being large in power, large in adhesion weight, large in traction capacity and the like, the spring sliding block type supporting device is simply and effectively combined with the side baffle and the traction rod device, and therefore the tractor has good operation stability; and the device is easy to manufacture and can be used for a liquid transmission rail car tractor or a traction motor body suspension type telex rail car.

    提供一种轨道工程牵引车用三轴转向架,框架由两根侧梁、两根中梁和端梁组成,两根侧梁上均对称布置有多组用于支撑车体的弹簧滑块式支撑装置,弹簧滑块式支撑装置与设于侧梁底部的侧挡和牵引杆装置形成了对车体的悬挂弹性支撑结构;相邻两组轮对组件中车轴上的车轴齿轮箱通过传动轴连接,实现动力驱动系统驱动下三个车轴齿轮箱的同步转动。本发明通过对支撑车体的支撑结构进行改进,在确保工程牵引车低成本和安全性能的前提下,具功率大、粘着重量大,牵引能力大等特点,简单、有效的将弹簧滑块式支撑装置与侧挡和牵引杆装置的组合,使得牵引车具有良好的运行平稳性,制造容易,可用于液传轨道车牵引车或牵引电动机体悬式电传轨道车。
