Description

A kind of vehicle frame and road rail vehicle

Technical field

The present invention relates to road transport field, in particular to a kind of vehicle frame and road rail vehicle.

Background technique

With the development of traffic capacity, the requirement that the owner of cargo is sent to timeliness to cargo is higher and higher, and various countries' railway is not Disconnected to be dedicated to improving freight delivery speed, effort forms the speed advantage that cargo is sent to, and gradually forms and be with Container Transport " door-to-door " transport represented.

Since starting is than later, transportation logistics industry development in China's lags behind always foreign countries, realizes railway " door-to-door " transport Equipment is only applied to Railway Container Transport field.But Railway Container Transport is always between " door to CFS, container freight station to door " transport It hovers free, is not carried out " door-to-door " transport truly.This situation makes railway freight in current high speed development In the logistics epoch, it is difficult to form complete logistics chain, whole journey logistics service can not be formed, seriously constrain railway transportation advantage Performance, cause railway transportation obviously to lag in Development of Logistics Industry.With the development of Chinese national economy, railway technology Policy clearly proposes that the goods train of diversified forms will be started, carries out through transport Extension Services, promote centralization transport and " door arrives Door " transport.

Currently, China realizes that the major way of " door-to-door " transport is the rail-road combined transportation of container, transportational process is： First by road automobile by container by distribution centre transport to railway container assemble yard, then railway transportation to container distribution Yard, finally Automobile Transportation is to field of receiving by road, and wherein highway transportation container generally uses Highway Container semitrailer to transport Defeated, railway transportation container generally uses container flat car or open-top car to transport.

In recent years the road rail vehicle developed uses the unit vehicle group organizational systems of one group of three vehicle, by 3 Highway Containers half Trailer, a pillow pulling assembly, two pillow pulling assembly, wind hand brake device, coupler and draft gear and 2 independent bogie groups At；When being used for railway transportation, the Highway Container semitrailer end at vehicle group both ends is led with a pillow pulling assembly and two respectively Assembly connection is rested the head on, end is assembled in pillow pulling and coupler and draft gear and bogie is installed in middle part Highway Container half in lower part respectively Bogie is installed in trailer lower part respectively, and installs wind hand brake device in a pillow pulling fit on, and road rail vehicle may be implemented Railway transportation；When being used for highway transportation, Highway Container semitrailer is detached from a pillow pulling assembly and two pillow pulling assembly, with On-highway tractor connects to form truck combination, realizes highway transportation.

The road rail vehicle of this split type structure has the following problems in actual use：

1, when highway turns railway transportation, need to increase a pillow pulling assembly, two pillow pulling assembly and bogie；Railway turns public affairs When road transport is defeated, needs to shed a pillow pulling assembly, two pillow pulling assembly and bogie, substantially increase transhipment time in this way.

2, road rail vehicle needs to carry out in dedicated place when highway and railway operation mode are mutually converted, and is equipped with The corresponding fork truck for carrying bogie, and converting field must have the hardening railway roadbed of suitable vehicle commander, road bed surface and the same height of rail level are simultaneously Can mitigate is transitioned on ground, then and participate in rail-road transport conversion railway station need to be arranged it is dedicated with bogie pillow pulling dress With storage space, in this way, the railway station quantity that rail-road can be used to convert will receive very big limitation.

For this purpose, we need to develop a kind of road rail vehicle to solve the above problems, wherein develop a kind of mountable The vehicle frame of big travel suspension and bogie is one of the difficult point researched and developed in road rail vehicle.

Summary of the invention

The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, and provide a kind of vehicle frame and road rail vehicle.
