JPH072103A - Outer bellows for vehicle - Google Patents

Abstract

PURPOSE:To provide an outer bellows for railway vehicles which suppress generation of the noise during traveling at high speed or on the curved rails, and is simple in structure and reliable by integratedly providing a packing material and a spring plate in the outer bellows of the shape of double-folding of the plate body made of flexible material. CONSTITUTION:An outer bellows 2 is connected to bracket 3 by bolts or the like at a connecting part of a vehicle 1. A packing material 4 and a spring plate 5 are connected to the inside of the outer bellows 2 with the adhesive or the like. a,d no packing material is provided at the part of the specified width (a) on the tip, and the air layer 6 is provided instead. This is because the danger that the outer bellows 2 or the outer bellows 2a may be broken in the middle due to contact and may not be restored is happened if the outer bellows 2 is brought close to the outer bellows 2a when the vehicle 1 enters the curved rails and if no air layer is present and the packing material 4 is swollen. By providing the air layer 6, the outer bellows 2 or 2a are returned to the original shape even if they are deflected. The spring plate 5 prevents the outer bellows 2, 2a from being bent.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad vehicle outer scale, and more particularly to a railroad vehicle outer scale suitable for a high-speed railroad vehicle.

[0002]

2. Description of the Related Art As a conventional technique, an inflatable multi-chamber hollow shape that can be adjusted to various stages with respect to the internal pressure through a compressed air system unique to a train and is connected to the outer circumference of a vehicle, When a plate-like body made of a flexible material such as rubber is folded back in two to form an outer scale on the vehicle's connecting part, it is attached so that it projects along the outer side of the vehicle and the inner side of the outer side There is an outside railroad railroad car with some pleats at intervals toward the top. Regarding these structures, Japanese Examined Patent Publication No. 1-43666 and Jikken Sho-41-
1683 and the like.

[0003]

SUMMARY OF THE INVENTION In the above conventional technique,
There is a need for a vehicle-to-vehicle connecting device other than the outside of the vehicle that can automatically adjust the strength of the outside of the vehicle according to the demands of high-speed traveling and curve traveling, and these cause an increase in weight. Also,
The vehicle-to-vehicle connecting device has an automatic control circuit incorporated therein and an electronic circuit for stepping the input signal therein,
There is a problem that we cannot keep up with the ever-changing situation.
Further, there is a problem that the system mechanism is complicated.

It is an object of the present invention to provide a simple and reliable outer rail for a railway vehicle which suppresses the generation of running noise during high-speed traveling and curve traveling.

[0005]

[Means for Solving the Problems] The above object is to fill a sponge or the like with a spring plate integrated inside an outer scale of a plate-like body made of a flexible material such as rubber and folded back in two. And by providing a portion of the air layer as needed.

[0006]

[Function] The outer scale is made of a soft material including a spring material and an air layer, and the gap between the outer scales is set to zero, or is set to be a little (10 mm or less), so that the outer scale can be used at a high speed or at a curve. The moles come into contact with each other and are slightly deformed, whereby interference with the outside moles can be prevented and running noise can be suppressed.

Further, by inserting a spring plate in the outside of the outside, it is possible to prevent bending of the inside of the outside by wind pressure, and
The spring plate accelerates the restoration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The connecting portion between the vehicles 1 has a through passage 1 through which a person passes.
0 is vacant, and the inner side of this is surrounded by the inner tip 11.
The outer scale 2 is substantially flush with the outer surface of the vehicle 1. The outer scale 2 is fastened to a bracket 3 attached to the vehicle 1 with bolts or the like. Also outside 2
The filler 4 and the spring plate 5 are bonded to the inner surface thereof by adhesion or the like, and there is no filler 4 and an air layer 6 is provided at a portion of the tip of the outer scale 2 having a predetermined width a. The reason for providing the air layer 6 is as follows. That is, when the vehicle 1 enters a curve, the outer scale 2a facing the outer scale 2 approaches. At this time, if there is no air layer 6 and the filling material 4 is full,
The contact causes the outer scale 2 or the outer scale 2a to be broken in the middle, and when the curve ends and enters a straight line, there is a danger that it will not return to its original shape. By providing the air layer 6, such a phenomenon only compresses the air layer 6, and the root of the outer scale 2, that is, the fixed portion side does not move. Therefore, when the vehicle 1 returns to a straight line, Outer side 2 is in a normal state. Further, a spring plate 5 is inserted between the outer scale 2 and the filler 4. Due to the presence of the spring plate 5, even if the outer plate 2 is pressed by the adjacent outer plate 2a and the outer plate 2 is bent, the original shape is restored. Further, the presence of the spring plate 5 has an effect of preventing the outer scale 2 from being bent inward by the vehicle exterior pressure generated when the vehicle 1 plunges into the tunnel at high speed. The spring plate 5 is put on the outside of the outer scale 2, but if it is put on both sides, the spring force is doubled and the restoration is further improved.

By making the vehicle 1 and the outer scales 2 and 2a flush with each other, that is, by making the outer surfaces flush with each other, the air flow is smoothed. Therefore, the turbulence of the air generated in the gap between the vehicles 1 is eliminated, and the generation of noise can be suppressed. Further, by forming the outer scale 2 into an inverted U-shape that extends to the end face of the vehicle 1 up to the skirt 8, the sound generated from the bogie 7 and the underfloor equipment at the bottom of the vehicle 1 is not leaked to the outside. The inverted U shape is used because the lower side is on the track and the side wall of the track has a soundproof wall (not shown), so that the distance from the sound source is increased. Furthermore, this is because the weight of the vehicle 1 is not increased by installing more devices than necessary. If the weight is increased, the orbit noise will be increased, and a large amount of electric power will be consumed.

Next, another embodiment of the present invention will be described with reference to FIGS. In this case, the portions that are in contact with each other may be provided with some gaps or may be in slight contact with each other, and the air layer has two stages. The outer side 2 at the end of the vehicle 1
There is a main air layer 6 in the area where the outer side 2 contacts.
Besides, this air layer 20 is provided. The air layer 20 is provided on a line inside the outer scale 2. This is because when the vehicle 1 is on the line that coincides with the outer surface, the vehicle 1 does not always protrude outside the outer scale 2 even when the vehicle 1 is biased. When the vehicle 1 travels on a straight line, the deviation amount is small, and the air layer 20
Only deforms. This is the outer scale 2 on the body side of the vehicle 1.
It's smaller, so you can move freely.

[0011]

As described above, according to the present invention, the gap between the outer scales is minimized, the inside of the outer scales is made up of the filler, the spring plate, and the air layer, and further, it is smooth with the vehicle body up to the skirt. By providing an inverted U shape including the above, it is possible to provide an outer railroad railroad vehicle railroad vehicle that can obtain the strength of the outer railroad wheels, suppress the generation of noise, and eliminate the interference between the outer railroad wheels due to the deviation of the vehicle. it can.
