Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a joint between two car bodies in a railway vehicle or the like, and in particular, the connected car bodies are tilted in the left and right direction to prevent the connected cars from moving relative to each other. This is a structure that does not cause target displacement, and furthermore, attempts to prevent the vehicle from swaying in the left-right direction itself.

[Prior art]

Conventionally, this type of coupling device, as typified by Japanese Patent Publication No. 53-47565, consists of a triangular truss extending from both car bodies and engaging the tip of the triangular truss to support a dome located between the two car bodies. Support mechanisms are known that are comprised of a plurality of links with a plurality of pivot points.

[Problem that the invention seeks to solve]

However, in such conventional techniques, the support structure consists of a large number of links and pivot points, and the members themselves are required to be able to expand and contract, so certain types of movements are restricted. There is a problem that it is difficult to operate smoothly.

Furthermore, the number of pivot points increases in order to accommodate movement in all directions, making the entire mechanism complex, and it is inevitable that assembly and maintenance will be time-consuming. Further, even with such a support structure, it is not possible to obtain the effect of suppressing the lateral movement of the vehicle body.

[Means for solving problems]

The present invention has been made to solve the problems of the prior art as described above, and the first invention is:
The core plate 1 provided on the truck has two core plates 2, 2' on the car body.
are mounted in sequence, the fitting surfaces of these core plates are spherical, and the connecting arms 14 and 14' are provided so as to be able to enter and exit from both vehicles in the longitudinal direction of the vehicle, and the connecting arms 1
A roof connecting device 18 in which 4 and 14' are connected by a connecting pin 13 is provided between both vehicles near the roof of the vehicle body, and the center plate and each center of the connecting pin 13 are arranged on a straight line in the vertical direction. The gist of the invention is a connecting device for vehicles such as railways, etc., and the second invention is a system in which core plates 2 and 2' of two car bodies are sequentially mounted on a core plate 1 provided on a bogie, and these core plates are fitted. The roof connecting device 18, which has connecting arms 14 and 14' whose mating surfaces are spherical and can be moved in and out from both vehicles in the longitudinal direction of the vehicle, and which is connected by a connecting pin 13, is attached to the roof of the vehicle body. Provided between two nearby vehicles, each center of the core plate and the connecting pin 13 being arranged on a straight line in the vertical direction,
The gist of the present invention is a connecting device for a vehicle such as a railway, which is characterized by having a gate-shaped member 11 fixed to a bogie and whose upper portion is connected to a connecting pin 13.

[Effect]

The operation of the device of the present invention is as follows.

That is, in the first invention, the body center plates provided on the suspension arms extending from both car bodies are sequentially mounted on the bogie center plate with a spherical fitting surface provided on the bogie, thereby reducing the vibration between the car bodies. The center is set at one point, and the connecting arms, which are movable in and out of the roof connecting device installed near the roofs of both car bodies, are connected to each other by connecting pins, and the core plate and the connecting pins are arranged on the same straight line in the vertical direction. By doing so, it is possible to eliminate the horizontal movement that occurs between the car bodies and allow other movements, and also to smoothly respond to the longitudinal angular displacement of both car bodies by the action of the elastic body built into the roof connecting device. This is what I did.

Further, the second invention is such that by adding a configuration in which the upper part of the portal member fixed to the beam of the bogie is connected to a connecting pin, the lateral movement of the car body itself can be suppressed by the bogie. This is what I did.

〔Example〕

The present invention will be explained below with reference to examples shown in the figures.

As shown in FIGS. 1 and 2, suspension arms 8 and 8' extending from two car bodies A and B are provided on a bogie centering plate 1 provided on an articulated bogie 6 having wheels 7. 2 and 2' are mounted one after another to connect the articulated bogie 6 and the two vehicle bodies A and B. The contact surfaces of these bogie center plates 1 and car body center plates 2, 2', that is, the mating surfaces of both the concave and convex surfaces, are finished into spherical surfaces, and are free only within a limited range in all directions with respect to the vertical straight line P. can move to.

On the other hand, a roof connecting device 18 is disposed between the two vehicle body roofs 17 to connect the upper part of the vehicle body. and the longitudinal centers of the core plates 2, 2' of the bogie and the two car bodies and the connecting arms 14, 14' of the roof connecting device 18.
The centers of the connecting pins 13 that connect the two are arranged so that they are on the straight line P, and the connected vehicle bodies are integrated to form a connecting device that does not displace relative to the inclination in the left and right direction.

The detailed structure of the roof connecting device 18 is as shown in FIGS. 3 to 6.
A connecting arm support 15 is fixed at a predetermined position near the upper end, and a connecting arm 1 has a connecting pin hole 20 at the tip.
4 and 14', an elastic body 16 such as a spring is interposed. Receiving plates 21 are arranged at both ends of the elastic body 16,
A locking piece 22 that engages with the outer surface of each receiving plate 21 is provided protruding from the lower surface of the connecting arms 14, 14'. Then, the tips of these connecting arms 14, 14' are overlapped,
Connecting pin 1 on the straight line between roofs 17
3 to be able to connect. The force of the elastic body 16 is adjusted so that the axis of the connecting pin 13 is on the longitudinal center line of both vehicles and at the center position between the two vehicles to maintain a neutral position on a straight and flat track. Position it accordingly. As a result, even if vertical displacement occurs between the connected vehicles, the connecting arms 14, 14' are moved in and out by the elastic body 16 and positioned on the center line of the truck.

The connecting arms 14, 14' are caused by the vertical angular displacement of the vehicle body that occurs when the vehicle passes along a track with a vertical curve.
As shown in FIGS. 6a and 6b, the expansion and contraction action of the receiving plate 21 that comes into contact with the stoppers 23 provided at the front and rear four corners of the lidded casing of the connecting arm support 15
It is regulated by , and can move in a range of M or N in the front-rear direction centering on the neutral position O. That is,
When the connecting arm 14' extends from the O direction to the M direction, the elastic body 16 shortens correspondingly, and conversely, when the connecting arm 14 extends from the O direction to the N direction, the elastic body 16 shortens correspondingly.

On the other hand, in order to suppress the lateral movement of the vehicle body itself, in this embodiment, the side supports are omitted and the gate-shaped member 11 is disposed at the center of the connecting portion. The lower end portions of both sides of the gate-shaped member 11 are properly fixed to the beams of the articulated truck 6, and the top portions are fastened together with the connecting pins 13 inserted through the connecting arms 14, 14' to directly transmit the vibration in the left and right direction to the truck. to suppress this.

This provides a more effective deterrent effect than using other means. A crosspiece 10 and a cover plate 12 are provided in the connected passageway to allow passengers to pass safely.

In this way, the connected vehicle bodies do not cause any relative displacement in the left-right direction of the vehicle, suppressing lateral sway, and can also be mounted on the connecting arm of the roof connecting device against angular displacement in the vertical direction of both vehicles. Due to the action of the elastic body, relative displacement is allowed around the vertical straight line P connecting the core plate and the connecting pin 13 against rotation in the horizontal plane.

〔Effect of the invention〕

This invention provides the following effects not found in conventional mechanisms.

First, the first invention realizes (1) a connecting mechanism that has a small number of pivot points and is easy to assemble and maintain;

(2) Smooth and effortless movement can be ensured in all directions.

Furthermore, the second invention (3) not only makes it possible to omit the side supports and eliminate the need for maintenance to deal with wear, but also effectively suppresses the lateral movement of the vehicle without using any special equipment. You can also get the effect that you can.
