The invention discloses a large-traction highway-railway dual-purpose tractor and a railway tractor train method, and relates to the technical field of highway-railway dual-purpose tractors. The tractor comprises a chassis, a front guide device, a front rubber wheel driving device, a rear guide device, a counterweight device and a traction device; the front rubber wheel driving device is connected to the front part of the vehicle body and comprises a telescopic driving device and a rubber wheel connected with the telescopic driving device; the telescopic driving device drives the rubber wheel to descend and ascend; the position of the balancing weight assembly on the vehicle body is adjusted under the driving of the chain transmission assembly; the continuous traction force of the highway-railway dual-purpose tractor is increased by adjusting the position of the counter weight and adjusting the bearing capacity of the rear guide wheel; during starting, the rubber wheels descend, and the tires and the rubber wheels jointly provide starting traction force for the train set; after operation, the rubber wheels are lifted and withdrawn, and continuous traction force is provided for the train set through the tires; the traction force of the tractor is more reasonably provided, and the problem that an existing highway-railway dual-purpose tractor is poor in universality is solved.
本发明公开了一种大牵引力公铁两用牵引车及铁路牵引车列方法,涉及公铁两用牵引车技术领域;牵引车包括底盘、前导向装置、前胶轮驱动装置、后导向装置、配重装置、牵引装置;前胶轮驱动装置连接在车体前部,前胶轮驱动装置包括伸缩驱动装置和与伸缩驱动装置连接的胶轮;通过伸缩驱动装置带动胶轮下降和上升;在链条传动组件的驱动下调整配重块组件在车体上的位置;本发明通过调整配重位置和调节后导向轮承载力来增大公铁两用牵引车的持续牵引力;起动时胶轮下降,轮胎和胶轮共同为车列提供起动牵引力;运行后上升收回胶轮,通过轮胎为车列提供持续牵引力;本发明牵引车牵引力提供更为合理,解决了现有公铁两用牵引车通用性差的问题。
