Abstract

The utility model provides an outer windshield for a motor train unit. The outer windshields are arranged on two side contour profiles of two end faces of each compartment. Each outer windshield comprises a windshield connecting frame, a rubber bag and press bars, wherein the windshield connecting frame is fixed on the end face of a train, the two ends of the rubber bag are fixedly connected with the windshield connecting frame through the press bars so that a closed U-shaped space is formed between the rubber bag and the windshield connecting frame. The outer windshield has the advantages of reducing influence of air resistance on the train, lowering and isolating noise outside the train, improving the running speed of the train and protecting the internal structure of the train.

Description

EMU is used outer windscreen

Technical field

The utility model relates to EMU, relates in particular to the outer windscreen of EMU vehicle junction.

Background technology

Train windscreen is the vitals of passenger train, between two joint vehicles.No matter vehicle is in any relative position, windscreen all keeps tight with vehicle and contacts, and prevents wind, sand, rain, snow, dust etc. into the car.Connect extension and in service at train, windscreen plays important effect.

The ordinary train windscreen is a single layer structure, is arranged on the end of adjacent two joint vehicles, and its chief component is the U type windscreen capsule that rubber elastic material is processed, and vehicle outline place is not provided with outer windscreen.Along with the appearance of EMU and improving constantly of running velocity thereof, the air rate in the ordinary train windscreen outside also improves constantly, and consequent noise just sees through windscreen and imports in the car, causes the interior noise of car higher, greatly reduces the comfort level that the passenger takes.

Individual layer windscreen structure also makes vehicle further receive air resistance influence, the speed when influencing the train high-speed cruising.

In addition; Individual layer windscreen structure makes train when high-speed cruising, because the high speed airflow influence of outside vehicle, the windscreen capsule outside and the bigger draught head of inboard formation; Cause the windscreen capsule to overturn to the inside easily and interfere each other, reduce the service life of windscreen with the parts around it.

Summary of the invention

In order to address the above problem, the utility model provides a kind of air resistance that can reduce that the EMU of the outer noise of influence, reduction and the runner wagon of train, raising train running speed and car comfort inside and protection train inner structure is used outer windscreen.

The said EMU of the utility model is used outer windscreen; Be arranged at two side profile places of two end faces of the every joint vehicle of EMU; Comprise windscreen connection box, capsule and press strip; The windscreen connection box is fixed on the vehicle end face, captives joint with the windscreen connection box through press strip in the capsule two ends, makes and forms an airtight U type space between capsule and the windscreen connection box.

The said EMU of the utility model is used outer windscreen, has following beneficial effect:

1, said capsule is a U type structure, makes the vehicle junction smooth smooth, thus the air resistance when reducing the train high-speed cruising.

2, said EMU is arranged on two side profile places of two end faces of every joint vehicle with outer windscreen; And said capsule is originally as U type structure; Thereby the low noise space through between in U type space and outer windscreen and the car makes car outer high velocity air noise, wheel and track friction noise, isolated layer by layer by electric system noise etc. and successively decrease the interior passenger's of assurance car traveling comfort; Because the present invention can reach the purpose that reduces noise, therefore reduced the noise reduction measure of taking to original train windscreen, simplified train composition.

3, the higher U type capsule of said rigidity has born the anticyclonic pressure that the train high-speed cruising is produced, thereby the air pressure that acts on each parts in the outer windscreen is reduced, and has improved the reliability and the service life of each parts in it.

In order to reach better effect, the said EMU of the utility model can also adopt following measure with outer windscreen:

1, with the cooresponding position of press strip some auxiliary holes is arranged on the said capsule.When capsule is fixed in the windscreen connection box through press strip, can utilizes these auxiliary holes to accomplish and install.

2, said capsule U type section top is 244.5mm to the distance of bottom.The capsule of adjacent like this two joint vehicles can closed contact, makes at vehicle when producing mutual dislocation through curve, can satisfy the mutual transversion malposition of vehicle keeping the changing of the relative positions each other under the prerequisite of better leak tightness between the capsule.

3, the height of said capsule is 2300mm, is made up of three sections circular arcs tangent to each other from top to bottom, and the radius of curve of these three sections circular arcs is respectively 798mm, 1998mm and 7998mm.It is 380 kilometers EMU that this size capsule is used for speed per hour.

4, the height of said capsule is 2295mm, is made up of three sections circular arcs tangent to each other from top to bottom, and the radius of curve of these three sections circular arcs is respectively 1898mm, 1998mm and 7998mm.It is 200 kilometers EMU that this size capsule is used for speed per hour.

The specific embodiment

In conjunction with Fig. 1 to Fig. 4 the said EMU of the utility model is elaborated with outer windscreen.

Embodiment one.

Embodiment one is that 380 kilometers EMU is used outer windscreen for speed per hour, like Fig. 1, Fig. 2 and shown in Figure 3.

Fig. 1 has described the installation site of the said EMU of the utility model with outer windscreen.Outer windscreen 2 is arranged at the every joint vehicle of EMU end face 1, divides left and right symmetrical part, is arranged at the both sides of vehicle end face 1 respectively, matees with the vehicle outline.

Fig. 2 and Fig. 3 have described 380 kilometers EMUs of speed per hour and have used outer windscreen.

As shown in Figure 2, the outer whole height L of windscreen of the type is 2300mm, is divided into epimere circular arc, stage casing circular arc and hypomere circular arc, and the three is tangent successively, and its radius is respectively R1=798mm, R2=1998mm, R3=7998mm.
