Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a connecting portion of two vehicle bodies with an articulated bogie and a flexible hood, and prevents deformation of the hood in response to mutual displacement of the articulated vehicle bodies on a curved road. Regarding connecting devices with less.

[Prior art and problems]

Displacements between vehicle bodies include displacement on curved roads, displacement due to rolling, displacement due to yawing, displacement due to pitching, etc. However, due to the structure of articulated vehicles, displacement due to the above-mentioned yawing and pitching hardly occurs.

In addition, any flexible canopy cannot avoid shearing deformation due to the displacement caused by rolling, but in articulated cars often used in streetcars with many small curves, the displacement on the curved road is the same as the mutual displacement of the articulated car bodies. It accounts for the majority.

In order to provide windproof and waterproof protection for the joints of articulated cars, it is necessary to cover the entire circumference of the passageway with a canopy as an integral piece. However, in the conventional joint device shown in FIG. A hood cloth 4 is attached in the longitudinal direction of the car body between an outer frame 2 connected to the through-way side wall 1 (fixed to the connecting part bogie) and the car body end face 3, and the car body center dish center 5 is aligned with the connection center 6. It was set at one point.

Note that this figure shows a case where only the right-hand vehicle body is on a curved road.

Therefore, when the articulated car bodies are mutually displaced by the angle ψ on a curved road, the displacement X of the top and bottom cloths 4 in the upper and lower parts of the joint in the sleeper direction and the shear deformation Y of the hood cloth itself become large, and the hood This impairs the durability of the cloth 4 and poses a problem in securing windproof and waterproof properties.

On the other hand, in order to eliminate the drawbacks of the prior art, as shown in FIG.
However, as shown in FIG. 8, the deformation of the hood cloth 4 is not as light as the conventional one.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention installs a flexible canopy in the radial direction of the vehicle body, and moves the center plate center position of the articulated vehicle body from the articulated center to approximately the visible part attachment position of the hood cloth in the longitudinal direction of the vehicle body. This is due to the eccentricity.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Note that the same parts as in the conventional example are given the same reference numerals.

FIG. 1 shows an embodiment of the present invention in which the hood cloth 4 in the conventional articulation device shown in FIG. It is something that

That is, the outer frame 2 is connected to the through-way side wall 1 (fixed to the connecting part bogie), and the hood cloth 4 is attached in the radial direction of the car body between the outer frame 2 and the guide column 7 on the car body's end face 3. .

The center disc center 5 of the articulated vehicle body is eccentric from the articulated center 6 by ε in the longitudinal direction of the vehicle body (ε approximately corresponds to the length to the visible part attachment position of the hood cloth 4). Note that this figure also shows the case where only the right-hand vehicle body is on a curved road.

Therefore, when the connected vehicle body is displaced by an angle ψ on a curved road, the displacement X of the hood cloth 4 in the sleeper direction and the shear deformation Y of the hood cloth 4 itself are 8 times smaller than that of the conventional one shown in FIG. 7, as shown in FIG. It is smaller than the figure.

Then, as shown in FIGS. 3 and 4, the articulated car body end surface 3
distance a% In the case shown in FIG. 3, the through-path width and the space between the side walls of the through-path can be made larger than in the case shown in FIG. 4, which is not eccentric.

That is, the through-path width, the through-path side wall spacing, and the remaining angle are w, b, , β1 in FIG. 4, and W2, bt in FIG.

becomes.

〔effect〕

Since the present invention is configured as described above, it has the following effects and is extremely useful.

(a) Since the displacement of the hood cloth attached to the entire circumference of the joint in the direction of the sleepers and the shear deformation of the hood cloth itself are extremely small compared to conventional ones, the durability of the hood cloth is improved and windproof and waterproof properties are ensured. .

(b) Since the hood cloth is attached between the outer frame and the guide post of the car body end, and the heart and blood center of the articulated car body is offset from the articulation center in the longitudinal direction of the car body, a large passageway width can be secured.
