Abstract

PURPOSE: To reduce a rolling stock internal sound and a rolling stock external sound emitted from a part between rolling stocks by surrounding the periphery of a roof between rolling stocks by a hood device where a surface of a foaming material mold is a sound absorbing layer and a hood upper part is a foaming material and has a bamboo hat-like cross-sectional shape approximated to an external shape of a rolling stock roof. CONSTITUTION: In two hood pleats 6, both side, upper and lower parts have the same cross section, and the mutual hood pleats are integrally joined together by a metallic frame 13. When a gangway hood device is installed on a rolling stock, an installing frame 18 is fixed to an installing seat 17 by a bolt 19, and the other end is fixed to an installing seat 17 by fastening metal 14 so that a hood side installing frame 15 is easily removed. Through part foaming body blocks (7a and b) have a width W and a height H, and are a single crest shaped block foaming body having a U-shaped groove. A material which is composed of a polyurethane type, a polyethylene type or a foaming material in the same system with a hood material and can excellently follow deformation of the hood pleats and whose sound absorbing force is comparatively high, is selected as a material having high shock absorbing resiliency, sound absorbing performance and adhesive strength in a hood pleat united body.

化が実施されていた。2. Description of the Related Art A hood device used between conventional vehicles is disclosed in Japanese Examined Patent Publication Nos. 45-26244 and 46-3656.
As described in No. 1 and Japanese Patent Publication, the hood is composed of an elastic body having a hollow cross section and a diaphragm shock absorber, and the air pressure inside the hood is automatically controlled to provide cushioning in the front and rear of the vehicle and air resistance by reducing the front and rear clearance. Some of them are intended to be reduced, or elastic cushions installed at both ends of the vehicle constitute a through path where rainwater does not enter between adjacent vehicles. Mitsuko Sho 41-16
In No. 83 and Japanese Utility Model Publication No. 56-45800, the platform passengers are prevented from falling or the air resistance of the train is reduced. In the latter case, noise emitted from the inter-vehicle area is reduced. Noise reduction was carried out by the hood with sound insulation function.

の問題があった。Among the above-mentioned prior arts, in which the hood is composed of an elastic body having a hollow cross section, air pressure is controlled by controlling the pressure inside the hollow hood in order to improve the ride comfort of vehicle vibration or running performance. It is intended to improve the followability by giving a spring function or changing the cross section of the hood to the movement of the hood when the vehicle runs on a curve. Next, the diaphragm shock absorber is an integrally molded product that surrounds only the through-passage made of an elastic material, and has a through-passage configuration that is less dangerous to passengers at the inter-vehicle connection, and is a low-cost component of the hood component. There is no known example of making noise. Next, a publicly known through-passage hood for high-speed vehicles is subjected to external pressure due to the effects of passing trains in the tunnel, etc., and the hood pleats are elastically deformed to cause inversion deformation. There is a problem of sound generation, strength, and short life of the hood. In terms of noise, there are problems such as a high level of noise such as rolling noise of a trolley that is transmitted to the inside of the vehicle through the hood, and high outside noise in the inter-vehicle area.

路幌装置を提供することにある。The object of the present invention is to prevent the deformation of the hood folds due to the external pressure of the through hood by adhering the integrally molded block of the foamable material to the outer periphery of the through hood and to prevent the foam material from generating noise in the inter-vehicle portion. It is an object of the present invention to provide a low noise type through road hood device for a high-speed vehicle that absorbs sound inside the vehicle and reduces the sound outside the vehicle emitted from the inter-vehicle portion.

Since the foam block with the groove is adhered and fixed for ease of use, even if external pressure is applied to the hood folds, the folds of the hood folds do not reverse and follow movements between vehicles. Further, the sound absorbing area is provided on the outer peripheral surface of the hood and around the roof, and in combination with the known side outer hood, the noise from the underfloor is enclosed and shielded to absorb the sound, so that the sound absorbing effect is improved.

It will load around mmAq. This external pressure may be further impacted by the passing trains, and in the bent hood fold, the reversal phenomenon becomes remarkable due to these external pressures. With respect to these external pressures, a foam material having a large thickness and a high waist with a sound absorbing function serves as a reinforcing body to enable pressure retention. Furthermore, the noise generated from the inter-vehicle area is due to the sound absorbing layer of foam material,
Since the sound absorbing layer in the roof surrounding shade portion absorbs and blocks sound, noise generation from this portion is small.

る押え板である。The through foam blocks 7a and 7b are monolithic block foams having a width W and a height H and U-shaped grooves, and have buffer elasticity, sound absorption, and As a material with high adhesive strength, we have selected polyurethane, polyethylene, or foam materials of the same type as hood materials, which have good followability to fold deformation and have relatively high sound absorption. S is the gap size of the single mountain block foam, and indicates the gap for avoiding the interference between the two when the vehicle is displaced. Reference numeral 11 denotes a shade-shaped foam block having a head portion adapted to the roof shape of the vehicle, which is an integral part of the penetration block 7 of foam. Reference numeral 12 is a displacement groove that facilitates the deformation of the through-hole foam 7. The cap-shaped foam blocks 11a and 11b are shaped so that the two blocks do not come into contact with each other to generate a gap 23. Also, this block is adhesively attached to the head fold, and since the foam on the roof side is the exterior surface of the car, it is assumed that it is wrapped with 21 weatherproof foam or tarpaulin material. There is. Reference numeral 20 denotes a displacement hole which facilitates the deformation of the cap-shaped foam 11. Reference numeral 22 is a retainer plate that prevents the generation of a space for connecting the end faces of the shade-shaped foam block 11.

騒音発生を防ぐ効果もある。In the above structure, in the displacement of the penetrating hood when the vehicle crosses the garage, the foam block is a unit of a U-shaped hood fold and has a displacement groove and a displacement hole. Because of this, these foam blocks, including the cap-shaped foam block, can easily be deformed and follow up even if they have the branching crossing deviation shape shown in FIG. Further, with respect to the external pressure, since the width and height in the deformation direction are relatively large in cross section, the hood fold is not deformed in the inversion direction, and it is possible to withstand a shocking high external pressure. Next, the noise from the floor
Sound is absorbed by the sound absorbing layer around the outside of the penetrating hood, which has the effect of significantly reducing running noise both inside and outside the vehicle, and also has the effect of preventing noise generation from this surface because the outer periphery of the inter-vehicle roof can be smoothed. .

However, when the vehicle-end damper is arranged above, the through-hole and the shade-like foam are not stuck to this. It can be configured by disposing the body block separately, or by scooping out the foamed body of the interference portion of the vehicle end damper arrangement. Further, in order to expand the sound absorbing area, it is common to mount the sound absorbing material on the end wall and the sound absorbing material on the rear surface of the outer hood. Further, although the through-hole foam block has a gap size of S, the foam itself is easily deformed by lowering the density of the foam, so that the gap size can be reduced. .
