The invention discloses a highway-railway combined transport vehicle sliding type air suspension which comprises a sliding type auxiliary frame assembly, installation frames are installed at the four corners of the sliding type auxiliary frame assembly, one end of an air spring is installed at the bottom of each installation frame, two transverse frames are fixedly installed on the sliding type auxiliary frame assembly, and the two transverse frames are fixedly installed on the sliding type auxiliary frame assembly. And two guide arms are installed at the bottom of each transverse frame, the same axle is installed on the two guide arms, and wheels are installed at the two ends of the axle. The suspension can slide manually within a certain range relative to the frame according to requirements, the position of the suspension is consistent with that of a common semitrailer during highway transportation, good axle load distribution effect and loading capacity are guaranteed, during railway transportation, the limit valve is opened manually, the suspension and the frame can slide, the suspension is moved to the center of the vehicle and then mechanically lifted, and the suspension can be moved to the center of the vehicle. An installation position is reserved for connection of the bogie, meanwhile, the load of goods is borne by the bogie, and highway-railway combined transportation conversion is completed.
本发明公开了一种公铁联运车辆滑动式空气悬架,包括滑动式副车架总成,所述滑动式副车架总成的四角位置均安装有安装架,安装架的底部安装有空气弹簧的一端,所述滑动式副车架总成上固定安装有两个横向架,且横向架的底部均安装有两个导向臂,两个导向臂上安装有同一个车轴,所述车轴的两端均安装有车轮。该发明悬架相对于车架可以在一定范围内根据需求手动滑动,在公路运输时,悬架位置与普通半挂车一致,保证了良好的轴荷分配效果和装载量,在铁路运输时,手动打开限位阀,悬架与车架可以滑动,悬架移至车辆中心位置,然后机械式抬起,给转向架的连接留出安装位置,同时货物的载荷由转向架承载,完成公铁联运转换。
