Description

[0001] The present invention relates to a door system for a railway vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door system installed in a railway vehicle, and more particularly to a door system for a railway vehicle having excellent blocking and sealing performance against external air inflow and noise and driving force.

Railway vehicles are a means of transportation that can be mass-shipped. In particular, recent high-speed trains have a driving performance of around 300km / h with electric power, so they have advantages over other transportation methods in terms of safety, convenience and environmental protection. .

High-speed trains operate passenger / freight combined high-speed vehicles and freight-only vehicles that can pass passengers and cargo together, as well as general railway vehicles. Both these passenger / By having an airtight structure, it is necessary to be able to block the inflow of outside air and noise during high-speed driving.

In particular, if the airtightness is not maintained, a door that serves as a passageway for passengers to / from the inside or outside of the train or a passageway for loading / unloading the cargo will generate high pressure air from the outside of the train during traveling of the train The door system must be provided with airtightness technology that can sufficiently withstand wind pressure and lateral pressure.

An example of a currently known technology related to a door system for a railway car is Korean Patent No. 10-1383497 (issued on Apr. 4, 2017, entitled " Belt-driven Railroad Vehicle Door Opener " .

The door opening / closing apparatus for a railway vehicle disclosed in this patent document provides a sliding type door using a belt pulley rotated in normal and reverse directions in a vertical direction and a drive belt moving in a horizontal direction with respect to the ground surface. A door lock mechanism for locking the door when the door body is in the closed position, a first limiter for confirming the closed state at the closed position of the door body, A switch, and a second limit switch for confirming an opened state at a position where the door main body is opened.

Therefore, there is a feature that the operation is more smooth and quiet than the conventional belt-driven power transmission configuration in which the belt surface is vertically erected with respect to the ground, and the lock holding device has a locking state when the door body is in the closed position So that unnecessary opening of the door main body can be prevented.

However, even if the conventional door system is applied to a general train or an electric train traveling at a low speed, it is difficult to maintain the airtightness when applied to a high-speed train traveling at a high speed of 300 km / h or more, Therefore, there is a problem that it is vulnerable to noise and vibration due to wind pressure and lateral pressure.

Meanwhile, electric door systems and pneumatic door systems can be considered as door systems for railway vehicles. The electric door system is a system that transmits the driving force of the electric motor to the door through the screw. It has excellent blocking / airtightness against external air and noise, and durability, which can reduce the maintenance cost. However, It is necessary to apply lubricating oil periodically and there is no case applied to a door system for a high speed train, and the airtightness is not verified. In addition, the pneumatic door system is applied to the high-speed freight trains of the French post office. It is the system that has been used for the longest time in the world. It is excellent in blocking / sealing against outside air and noise, Improvement of confidentiality technology is required.
