Highway and railway dual-purpose vehicle

Abstract

The invention discloses a highway and railway dual-purpose vehicle which comprises a vehicle frame. Lifting air bag installation seats are arranged between two longitudinal beams of the vehicle frame.Bearing air bag insertion holes are formed in lower cover boards of the longitudinal beams. Bearing air bag installation seats are arranged in the bearing air bag insertion holes. Force bearing sleeper beams are installed on the outer sides of the longitudinal beams. A suspension comprises an axle assembly with lifting air bags arranged on the middle portion at the front end. First-level bearingair bags are arranged on the two sides at the rear end of the axle assembly. The two first-level bearing air bags are provided with second-level bearing air bags. The lifting air bags are arranged onthe lifting air bag installation seats. The second-level bearing air bags are installed in the bearing air bag installation seats. Each single-axle bogie comprises a framework. Axle boxes are arrangedat the two ends of the bottom face of each framework. A first-system damping spring assembly is arranged between each axle box and the corresponding framework. Vehicle frame connecting assemblies arearranged at the two ends of the top face of each framework. The frameworks are arranged on the bottom faces of the force bearing sleeper beams through the vehicle frame connecting assemblies. The highway and railway dual-purpose vehicle is suitable for transport.

Description

technical field [0001] The invention relates to the field of road transportation, in particular to a road-rail vehicle. Background technique [0002] With the development of transportation capacity, cargo owners have higher and higher requirements for the timeliness of cargo delivery. The railways of various countries are constantly committed to improving the speed of cargo delivery, striving to form the speed advantage of cargo delivery, and gradually form container transportation. "Door to door" transportation. [0003] Due to a relatively late start, the development of my country's transportation and logistics industry has been lagging behind foreign countries, and the realization of railway "door-to-door" transportation equipment is only used in the field of railway container transportation. However, railway container transportation has always been wandering between "door-to-station and station-to-door" transportation, and has not realized "door-to-door" transportation ...

AI Technical Summary

Problems solved by technology

[0007] 1. When transporting from road to railway, it is necessary to add one sleeper assembly, two sleeper assemblies and bogies; when transferring from railway to road, it is necessary to remove one sleeper assembly, two sleeper assemblies and bogies, so that Greatly increased transit time

[0008] 2. When the road and railway operation modes are switched between road and railway vehicles, it needs to be carried out in a dedicated site, and the corresponding forklift truck for moving the bogie must be equipped, and the conversion site must have a hardened ballast bed suitable for the length of the vehicle, and the ballast surface and the rail surface The same height and can ease the transition to the ground, and the railway stations that participate in the conversion of public-rail transportation need to set up special assembly and storage sites for traction pillows with bogies. In this way, the number of railway stations that can use public-rail conversion will be greatly reduced. limit
