The invention discloses a highway-railway dual-purpose traction locomotive which comprises a frame, a railway walking mechanism and a highway walking mechanism are installed on the frame at the same time, and the highway walking mechanism comprises a pair of steering wheel sets installed at the front end of the frame and a pair of driving wheel sets installed at the rear end of the frame. The steering wheel sets and the driving wheel sets are arranged in a bilateral symmetry mode relative to the frame, hydraulic lifting mechanisms are connected to the steering wheel sets and the driving wheel sets, a steering platform assembled in a rotating mode is arranged in each he steering wheel set, and a hydraulic steering cylinder driving each steering platform to rotate in a reciprocating mode is connected to the steering platform. A hydraulic driving motor is in transmission connection with a wheel shaft of each driving wheel set. Meanwhile, a hydraulic pump driving system for driving the hydraulic lifting mechanisms, the hydraulic steering cylinders and the hydraulic driving motors to work respectively is mounted on the frame. The shunting operation of the traction locomotive can be independently completed without depending on a turnout system, and the traction locomotive has the characteristics of simple overall structure and convenience and rapidness in operation, and effectively solves the problems in the prior art.
本发明公开了一种公铁两用牵引机车,包括车架,在车架上同时安装有铁路行走机构和公路行走机构,其公路行走机构包括安装于车架前端的一对转向轮组和安装于车架后端的一对驱动轮组,转向轮组与驱动轮组均相对于车架左右对称布设,并在转向轮组与驱动轮组上均连接有液压升降机构,转向轮组中设有转动装配的转向平台,转向平台上连接有驱动其往复转动的液压转向缸,在驱动轮组的轮轴上传动连接有液压驱动马达,同时在车架上安装有驱动液压升降机构、液压转向缸和液压驱动马达分别工作的液压泵驱动系统。本发明可以不依赖道岔系统独立完成牵引机车的转轨作业,其具有整体结构简单、操作方便快捷的特点,有效的解决了现有技术存在的问题。
