The invention discloses a wheel-track combined type semi-trailer tractor and a traction method thereof. The wheel-track combined type semi-trailer tractor comprises a frame, a track assembly and two groups of rear axle assemblies. Wherein the track assembly is arranged at the head end of the frame and comprises a saddle and a track chassis; each rear axle assembly comprises a swing arm and a tire assembly, and the two swing arms are hinged to the two sides of the connecting support through pin shafts respectively. The loading capacity and the running power performance of traction equipment can be effectively improved, the turning radius is reduced, meanwhile, the transverse moving function can be achieved, and the transfer requirement of large equipment in a mining area is met.
本发明公开了一种轮履组合式半挂牵引车及其牵引方法,其中所述轮履组合式半挂牵引车包括:车架、履带总成和两组后桥总成。其中,履带总成,其设置在所述车架的头端,包括鞍座和履带底盘;两组后桥总成,每组后桥总成包括摆臂和轮胎组件,两个摆臂分别通过销轴与连接支架的两侧铰接。本发明可有效提高牵引设备的载重能力和行驶动力性能,缩小转弯半径,同时可以实现横移功能,满足矿区大型设备的转运需求。
