The invention relates to a highway-railway dual-purpose single-shaft driving tractor which comprises a tractor frame, a highway wheel train assembly and a railway wheel train assembly. The road wheel train assembly comprises a road bogie, bogie tires, a road driven frame and driven frame tires. The railway wheel train assembly comprises a railway driven bogie, driven frame steel wheels and a highway-railway dual-purpose single-shaft driving assembly, the highway-railway dual-purpose single-shaft driving assembly comprises an axle, driving frame steel wheels, a driving system and friction hubs, and the friction hubs are arranged on the outer sides of the driving frame steel wheels at the two ends. The rim of the friction hub is meshed with the rim of the driven frame tire, and the friction hub rotates to drive the driven frame tire to rotate. A four-wheel walking structure is adopted in the highway mode and the railway mode and is achieved through driving frame steel wheels, the tractor is small in size, shunting operation is flexible, a special garage is not needed for storage, and the repair and maintenance cost is low; the working route of the tractor is short, railway layout design is simplified, the number of tracks and the number of track forks are reduced, and railway construction investment is reduced.

    本发明涉及一种公铁两用单轴驱动牵引车,包括车架、公路、铁路轮系组件;公路轮系组件包括公路转向架、转向架轮胎、公路从动架以及从动架轮胎;铁路轮系组件包括铁路从动转向架、从动架钢轮以及公铁两用单轴驱动组件,公铁两用单轴驱动组件包括车轴、驱动架钢轮、驱动系统以及摩擦轮毂,摩擦轮毂设置在两端驱动架钢轮的外侧,在公路模式下,摩擦轮毂的轮缘与从动架轮胎的轮缘啮合,摩擦轮毂转动带动从动架轮胎转动。本发明在公路模式和铁路模式均采用四轮行走结构,均是通过驱动架钢轮实现,牵引车积小,调车作业灵活,不需要专门的车库存储,维修、保养成本低;牵引车的工作路线短,简化铁路布局设计,减少轨道数和道叉数,降低铁路建设投资。
