Description
Technical field
The invention belongs to administrative region of a city rolling stock technical fields, more particularly, to a kind of system of administrative region of a city railroad car
Make technique.
Background technique
Administrative region of a city railway, also referred to as Rail Transit are being filled with railway technology of specially runing between neighbour city, city
City common-rail traffic system based on standby is that connection city proper and suburb and tens kilometers of peri-urban are even more big
The satellite of range or the fast high-capacity public transport public transport mode of urban agglomeration.Generally based on certain panel region, administrative region of a city
The coverage positioning of railway reflects the city integrated Rail Transit System of " the outer Tie Tong of internal rail is intercity ".When administrative region of a city railway operation
For speed generally between 120~200km/h, station spacing is smaller, and it is between city rail that this route, which is typically all to be directly entered urban district,
Novel rail Transportation Model between road traffic (subway, light rail) and inter-city high-speed rail, the tracks such as existing subway, light rail
Restriction of the traffic form by the speed of service has been unable to reach the target expectation of resident trip in urban construction, with city rail
Traffic is compared, it has averagely station spacing is larger, passenger capacity is big, speed target value is high, travelling speed is high, rate of traffic flow is moderate etc.
Feature, moreover it is possible to which realization is interconnected with state-owned railroads main line, enhances urban outbound radianting capacity.
Administrative region of a city rolling stock primary structure includes: the parts such as pulling equipment, bogie, car body, and wherein car body is vehicle
One of main composition main body, car body be both passenger seating carrier and installation and connect other several component parts (such as:
EEF bogie, brake apparatus, coupling device at car end, vehicle interior decorating apparatus etc.) basis.
Since administrative region of a city railroad car is different from train of high-speed motor train unit body construction, existing train of high-speed motor train unit
Car body manufacturing process is unsuitable for the manufacture of administrative region of a city railroad car, and there is no administrative region of a city railroad car manufacturing process now
The disclosure of process patent, therefore a kind of manufacturing process flow suitable for administrative region of a city railroad car is formulated, production efficiency is improved, is
Those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of manufacture of administrative region of a city railroad car
