Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an outer hood for a railway vehicle that covers a connecting portion of a vehicle, and more specifically covers the entire circumference of a space portion between front and rear vehicles, and transmits the wind noise of the vehicle and the noise in the vehicle deck portion to the inside of the vehicle. The present invention relates to an outer hood for a railway vehicle that is excellent in durability and capable of following a large deformation in a curve with a small curvature at a yard.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a vehicle hood that covers a space between high-speed railway vehicles is composed of an inner hood that covers the entire inner periphery between vehicles and an outer hood that covers only the left and right side surfaces of the vehicle outside the vehicle.
[0003]
An inner hood provided in the vehicle connecting portion is formed in a bellows structure and serves to protect the inside of the vehicle from wind and snow, dust, etc., and the outer hood is a rubber having a U-shaped cross section attached to the side surfaces of the front and rear vehicles. It consists of a plate and has an aesthetic appearance of the vehicle connection part, and has also played a role in preventing passengers from falling from the platform of the station to the track in the space between the vehicles.
[0004]
[Problems to be solved by the invention]
However, the above-mentioned vehicle hood has been considered to be sealed in order to prevent intrusion of wind and snow, dust, etc., but no sufficient measures have been taken against noise. Because it is not arranged all around the connecting part of the vehicle, wind noise, friction noise between wheels and rails, tapping noise at rail joints, wheel rolling noise, pantograph rubbing noise, resonance when passing through an iron bridge There was a problem that sound, etc. entered the vehicle directly through the inner hood.
[0005]
In addition, when traveling on a track with a small radius of curvature at a yard or the like, the outer hood provided on the left and right side surfaces of the vehicle cannot flexibly respond, and the outer hoods come into contact with each other to shorten the life. .
[0006]
An object of the present invention is to provide a railcar outer hood that is excellent in durability while reducing noise from outside the vehicle transmitted to the inside of the vehicle.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an annular outer hood comprising a rubber plate that covers the entire circumference of a space portion between vehicles in a connecting portion of front and rear vehicles, wherein both ends of the rubber plate in the vehicle front-rear direction are connected to the outer hood. The annular front and rear end portions are formed by projecting to the annular inner side, and the annular front and rear end portions are configured to be attached to the vehicle. When a U-shaped deformation / following portion is formed, and the rubber plates of the outer hood main body facing the vehicle longitudinal direction across the deformation / following portion in the cross section of the outer hood are in the same straight line in the vehicle longitudinal direction In addition, an opening having a U-shaped cross section of the deformation / following portion is opened with a gap, and in the cross section of the outer hood, near the inside of the outer hood of the base portion of the deformation / following portion, Inside the outer hood from the position where the outer hood is attached The support beams rubber for connecting the position and to be linear, it is an summarized in that provided on a part of the annular or circular over the entire circumference of the outer hood periphery.
[0008]
Here, in consideration of the productivity of the outer hood and the workability of attachment, the deformation / following portion is a rubber plate having a U-shaped cross section configured to be detachable from the rubber plate of the outer hood main body .
[0009]
In addition, in order to maintain the rigidity of the outer hood, in the cross section of the outer hood, in the vicinity of the inner portion of the base of the deformation / following portion, the position in the outer hood inner side than the position where the outer hood of the front and rear vehicles is attached The support beam rubber which connects the two in a straight line is reinforced by providing the support hood rubber over the entire circumference of the outer hood or on a part of the circumference of the outer hood .
[0010]
Here, a reinforcing layer can be embedded in the deformation / following portion and the rubber plate of the outer hood main body, and a reinforcing layer can be embedded in the support beam rubber. With such a configuration, wind noise, wheel-to-rail friction noise, tapping noise at the rail joint, wheel rolling noise, pantograph rubbing noise, resonance noise when passing through an iron bridge, etc. from outside the vehicle It is possible to reduce the noise transmitted to the vehicle through the inner hood by temporarily blocking the noise.
[0011]
Furthermore, when traveling on a track with a small radius of curvature at a yard or the like, the rubber plate is deformed around the deformation / following part, so that the outer hoods are not damaged by contact with each other and the durability is improved. It is possible to make it.
