Problems solved by technology

When driving at high speed, the pressure difference between the inside and outside of the car body increases. If the sealing performance of the side sliding door does not meet the requirements for use, there will be safety hazards or affect the driving of the car.
[0004] The driving method of the existing side sliding door is mainly hydraulic pressure or oil pressure. The disadvantage of this type of hydraulic pressure sealing device is that the pressure is unstable. It directly affects the sealing ability, and with the increase of the pressure difference inside and outside the car body, the sealing ability of the hydraulic drive will also decrease, which obviously does not meet the performance requirements of high-speed rail vehicles
[0005] In addition, the pipeline of the hydraulic drive device is prone to leakage due to excessive local pressure, which requires regular maintenance or refilling of hydraulic oil, resulting in increased vehicle operating costs

Embodiment Construction

[0048] Such as Figure 1 to Figure 7 As shown, the rail vehicle side sliding door is integrally arranged inside the car body 4, and the door body 1 is pressed and sealed to the door frame 10 on the car body by the control device 2 .

[0049] The side sliding door mainly includes a door body 1 , a control device 2 , a reset adjustment device 3 , a drainage assembly 5 and an isolation lock 6 . in,

[0050] The control device 2 is used to control the opening and closing action state of the door body 1;

[0051] The reset adjustment device 3 is to realize the state before the door body 1 resumes action in the open state;

[0052] After the door body 1 is closed, the pressure acting on the door body 1 is maintained by the control device 2 .

[0053] The side sliding door adopts an electro-pneumatic built-in structure, and the compression sealing of the side sliding door is realized by the air pressure locking part 22 . After the compressed air is input into the air pressure lin...

Abstract

The invention discloses a side sliding door of a railway vehicle. The side sliding door adopts an integrally built-in type door body and a driving mechanism to tightly compress a vehicle door through a revolving bar type air-pressure driving structure instead of a conventional hydraulic driving device, thereby realizing continuity and stability of pressure in the process of compressing and sealing. Good compressing and sealing between the side sliding door and the vehicle door is realized through the adoption of an air-pressure driving principle, and better sealing performance can be kept under the circumstance of increased differential pressure inside and outside the vehicle door. The side sliding door comprises a door body, a control device for controlling action state of opening and closing of the door body and a resetting adjustment device which realizes recovery of door body state before action in an opening state. The side sliding door is integrally arranged on the inner side of a vehicle body, and the door body is tightly compressed onto a door frame of the vehicle body through the control device. After the door body is closed, pressure exerted on the door body is maintained through the control device. The control device is provided with a driving part adopting pneumatic outputting, an air-pressure locking part and an electromagnetic valve which controls air-pressure output to the driving part and the air-pressure locking part.

Description

technical field [0001] The invention relates to a structural improvement of a side sliding door of a rail vehicle, and specifically adopts a novel air pressure driving principle to realize compression and sealing between the side sliding door and a car body, and belongs to the field of mechanical manufacturing. Background technique [0002] With the current domestic main line railway and urban light rail transit operation speed greatly improved, higher design standards have been put forward for the safe use and structural stability of vehicle supporting facilities. [0003] For rail vehicles with a speed of more than 380 km / h that have been put into use in China at present, the safe use and sealing of the side doors are more critical. When driving at high speed, the pressure difference between the inside and outside of the car body increases. If the sealing performance of the side sliding door does not meet the requirements for use, there will be safety hazards or affect the...
