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

[Conventional technology and problems]

Mutual displacements between vehicle bodies include displacements on curved roads, displacements due to rolling, displacements due to yawing, and displacements due to pitching, but due to the structure of articulated vehicles, the above-mentioned displacements due to yawing and pitching hardly occur.

In addition, for the displacement due to the rolling mentioned above,
Any flexible canopy is subject to shear deformation, but in articulated cars often used in streetcars with many small curves, displacement on curved roads accounts for most of the displacement between the articulated car bodies.

In order to provide windproof and waterproof protection for the joints of articulated cars, it is necessary to use a canopy as an integral part to cover the entire circumference of the passageway, but in the conventional joint 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 plate 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, on a curved road, the articulated vehicle body has an angle ψ
As shown in FIG. 6, when the hood cloth 4 at the upper and lower portions of the connecting portion is displaced in the sleeper direction, the displacement X and the shear deformation Y of the hood cloth itself become large, impairing the durability of the hood cloth 4, and reducing wind protection. There was a problem with ensuring waterproofness.

On the other hand, in order to eliminate the drawbacks of the prior art, as shown in FIG. 7, there is a vehicle in which the center plate center 5 of the vehicle body is eccentric with respect to the connection center 6 by ε.
As shown in FIG. 8, the deformation of the hood cloth 4 is not significantly reduced compared to the conventional one.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention mounts the flexible hood 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 flexible portion attachment position of the hood cloth along the longitudinal direction of the vehicle body. This is because it is eccentric in the direction.

〔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 truck), and the outer frame 2 and the guide column 7 of the car body end face 3 are connected to each other.
A hood cloth 4 is attached in the radial direction of the vehicle body between.

The center plate 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 flexible portion 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 7th
It is smaller than the conventional one shown in FIG. 8.

As shown in FIGS. 3 and 4, when the distance a between the articulated vehicle body end surfaces 3, the inner radius γ of the guide column 7, and the displacement angle ψ of the articulated vehicle body on a curved road are equal, the articulated vehicle body The one shown in FIG. 3 in which the center disk center 5 is displaced by ε from the connection center 6 in the longitudinal direction of the vehicle body can make the through-path width and the through-path side wall interval larger than the one shown in FIG. 4, which does not have eccentricity. .

That is, the through-path width, the through-path side wall spacing, and the remaining angle are W ₁ , b ₁ , β ₁ in FIG. 4, and W 1 , b 1 , β 1 in FIG.
Assuming W ₂ , b ₂ , β ₂ , W ₁ =2γ sinβ ₁ , W ₂ =2γ sinβ ₂ b ₁ =2γ sin(β ₁ +ψ), b ₂ =2γ sin(β ₂ +ψ), and β ₂ > Since β ₁ , W ₂ >W ₁ and b ₂ >b ₁ .

〔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 connecting part 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
Waterproofing is guaranteed.

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