Enclosed stainless steel train windscreen

Abstract

The invention discloses a full-sealing typed stainless train windshield, mainly consisting of the multi-waved stainless steel expansion joints and the flange discs corresponding to the width of the carriage door or the carriage end. The flange discs are circularly welded at the two ends of the multi-wave stainless steel expansion joints; the internal layer and / or external layer of the multi-wave stainless steel expansion joints can be provided with reflection coating or polyamide coating or attached plastic membrane. Owning to the use of mature large stainless steel expansion joint production technology, the invention rolled by stainless steel with good flexibility and high quality leads the train windshield metallization to come true; furthermore, the invention mainly consists of the stainless steel expansion joints and flange discs, thus obviously having the advantages of more simple and reasonable structure, good high and low temperature-resistance performance, anti-vibration, sound insulation, good heat preservation, long service life, convenient disassembly and assembly, low maintenance cost and beauty, being the updating product for the existing train windshield.

Description

technical field [0001] The invention relates to a windshield for a train, in particular to a windshield suitable for high-speed trains installed between carriages, and belongs to the field of railway vehicles. Background technique [0002] The windshield is an important connecting part between the carriages of railway cars, which plays an important role in sealing the internal passage between the carriages. Since the train runs on the rails, each carriage must turn with the turning of the rails. As the rail goes up and down, the windshield connected between the carriages must be a sealed structure with good telescopic and bending performance. The existing windshields mainly include single-layer bellows windshield and double-layer bellows windshield. Its structure is mainly composed of several rectangular metal frames and tarpaulin sewn on the frame. It has the characteristics of simple structure and low production cost, but the tarpaulin is easy to be damaged, pulled off and...

Problems solved by technology

[0002] The windshield is an important connecting part between the carriages of railway cars, which plays an important role in sealing the internal passage between the carriages. Since the train runs on the rails, each carriage must turn with the turning of the rails. As the rail goes up and down, the windshield connected between the carriages must be a sealed structure with good telescopic and bending performance. The existing windshields mainly include single-layer bellows windshield and double-layer bellows windshield. Its structure is mainly composed of several rectangular metal frames and tarpaulin sewn on the frame. It has the characteristics of simple structure and low production cost, but the tarpaulin is easy to be damaged, pulled off and broken, resulting in short service life and requiring frequent maintenance. Replacement, but the disassembly and installation process is complicated, which makes loading, unloading and replacement difficult, and the maintenance cost is high. At the same time, there are obvious defects such as ugly appearance, poor sound insulation and heat insulation effect, and it is still widely used on ordinary trains.

As the speed of the train continues to increase, it is imperative to use a sealed windshield. The traditional bellows-type windshield can no longer meet the needs of high-speed trains, especially when the running speed reaches and exceeds 160 kilometers per hour, it is necessary to use a windshield with better performance. Windshields, such as the folded sealed windshields and sealed rubber windshields used on the recent express passenger cars and EMUs, have the advantages of good air tightness, vibration isolation, sound insulation, and heat insulation, which greatly improve the comfort of passenger trains and security

However, due to the aging of rubber and shed cloth, there are also obvious shortcomings such as short service life and high replacement and maintenance costs.
