Highway-railway convertible car

Abstract

The invention discloses a highway-railway convertible car, comprising a highway container semi-trailer, a one-position traction bolster assembly, a two-position traction bolster assembly, a coupler buffer device, a bogie and an air and manual brake device. The highway container semi-trailer comprises a frame, container locks, ground jacks, a suspension damping system and protective devices. Two parallel centre sill assemblies are welded by adopting connection plate assemblies, to form the main part for bearing the railway longitudinal force; a secondary hook and a primary hook serve as the connectors and are connected with traction bolster assemblies at the head and the tail, so that the highway-railway convertible car can meet the requirement of railway transportation; when the highway-railway convertible car is used for railway transportation, a rear protective device is overturned upwards from the outside of the car around a rotating shaft, so that the requirements of assembling the railway bogie and the car body are met; and the suspension damping system adopts vibration damping gasbag and lifting gasbag structures, so that the matching of the highway container semi-trailer, a highway semi-trailer tractor and the bogie of the highway-railway convertible car during the conversion between highways and railways and the requirement of the gap between the road tire and the lower margin during railway transportation are met.

Description

technical field [0001] The invention belongs to the field of railway vehicles, and in particular relates to a road-rail vehicle. Background technique [0002] The road-rail vehicle is a special vehicle for transportation on roads and railways. During road transportation, the railway bogie is removed, and the road tractor is connected to the road container semi-trailer for road transportation; during railway transportation, the road container semi-trailer is mounted on the railway bogie, and the car tires are lifted by coil springs or hydraulic devices. After being lifted, it is assembled with the traction pillow and the coupler buffer device to form the railway train transportation. [0003] Existing road container semi-trailers are generally divided into skeleton structure and flat structure. Skeleton frame is welded by longitudinal beams, cross beams, front end beams and rear end beams. The longitudinal beams are made of high-quality steel plate 16Mn submerged arc welded...

AI Technical Summary

Problems solved by technology

However, the frame structure strength, rigidity and fatigue characteristics of the existing road container semi-trailer can only meet the requirements of road transportation. The frame will bear the longitudinal force of the railway, but the strength and rigidity of the existing frame structure cannot meet the requirements of the longitudinal impulse of railway transportation
