Problems solved by technology

[0002] Based on the characteristics of fast boarding and landing, the new intercity EMUs mostly use double-opening plug doors with large openings. However, since the operating environment of intercity EMUs is mostly leaky and unobstructed, the requirements for airtightness and watertightness of vehicles are relatively high. High, the existing large-opening double-opening plug doors cannot well meet the requirements of the vehicle's airtightness and watertightness

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as figure 1 with figure 2 As shown, a rail vehicle double-opening plug-and-pull door system provided by the present invention includes two side-opening door leaves 1 and a door frame 2, and the door frame 2 is fixed on the car body steel structure (not shown in the figure) by bolts. On the butt joint surfaces of the two door leaves 1, there are centering sealing strips symmetrically arranged, which are respectively the centering sealing strip 3 installed on the left door leaf 1 and the centering sealing strip 4 installed on the right door leaf 1. Circumferential sealing rubber strips 5 are arranged on the connection surfaces where the top, bottom and side of each door leaf 1 are connected with the door frame 2 .

[0025] Such as figure 1 As shown, both the centering sealing strip 3 and the centering sealing strip 4 include a firs...

Abstract

The invention relates to a double sliding-plug door system of a rail vehicle. The double sliding-plug door system comprises two side-by-side door leaves and a door frame, the door frame is fixed to avehicle body steel structure, and centering sealing rubber strips are symmetrically arranged on the butt-joint faces of the two door leaves; and the connecting face where each door leaf is connected with the door frame is provided with a circumferential sealing rubber strip, at least one of the centering sealing rubber strips comprises a first mounting part and a first sealing part, the first mounting parts are fixedly connected with the door leaves, and an outer side sealing lip edge flanging towards the outside of the vehicle is at least arranged on the vehicle outer side of one first sealing part. The double sliding-plug door system of the rail vehicle plays a good air sealing effect, meanwhile, watertightness is more facilitated, and the good water sealing effect is achieved.

Description

technical field [0001] The invention relates to a rail vehicle door system, in particular to a rail vehicle double-opening plug-and-pull door system, which belongs to the technical field of rail vehicle manufacturing. Background technique [0002] Based on the characteristics of fast boarding and landing, the new intercity EMUs mostly use double-opening plug doors with large openings. However, since the operating environment of intercity EMUs is mostly leaky and unobstructed, the requirements for airtightness and watertightness of vehicles are relatively high. High, the existing large-opening double plug door can not well meet the requirements of the airtightness and watertightness of the vehicle. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a track that can effectively improve the airtightness and watertightness of the car door, make the door meet the airtightness and watertightness index of the vehicle,...
