Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a suspension link receiving portion of a monorail structure (vehicle body).

[Conventional technology]

A schematic diagram of the entire monorail vehicle is shown in FIGS. 5 and 6, and a conventional mounting structure of the monorail vehicle body suspension mechanism on the vehicle body side (detailed view of section A in FIG. 6) is shown in FIGS. 3 and 4. show.

To explain the overall structure, the monorail car body 01 has a suspension link receiver 03 fixed to the car body roof beam part 02 at two places, front and rear, as shown in FIGS. 3 to 6.
It is suspended by a suspension link 05 via a pin 04, and the suspension link 05 is suspended from a pin 011 provided at the upper end.
It is attached to the running wheel unit 06 so as to be swingable in the left and right directions, and has a structure that allows it to move back and forth on the elevated running surface 07.

Now, the above-mentioned suspension link 05 is integrated into one block at the front and rear on each side of the left and right sides, and the mounting portion on the vehicle body side is connected to the vehicle roof beam portion 0 through the pin 04.
Suspension link supports 03 installed at four locations are suspended. The suspension link receiver 03 is mounted on the upper flange of a roof structure link receiver beam made of welded frames with the roof plate 08 sandwiched therebetween, and is fastened with mounting bolts 09. A reinforcing plate 010 is provided on the back side of the flange of each beam of the mounting bolt fastening part,
The other side of the corresponding plate reinforcement 010 was bolted to the web of the beam, taking into consideration the relaxation of the load on the flange and the distribution of the load to the web.

[Problem that the invention attempts to solve]

The conventional structure described above has the following problems: (1) Because four separate suspension link supports are used for one set of suspension links, the transmission force between the suspension links and the vehicle body becomes complicated. , the force transmission path becomes longer.

(2) Due to the reason stated in item (1) above, the required strength of the suspension support structure increases, which increases the weight.

(3) Since the suspension link receiver is separated into four pieces, it is not possible to easily adjust the level of the link.

[Means for solving the problem] Four suspension link holders per set of suspension links, which were conventionally used when attaching suspension links to the roof beam of the vehicle body, are integrated into an integrated structure, that is, one block. . The link receiving block is engaged with the lower surface of the vehicle roof beam to support the vehicle roof beam from the lower surface.

[Effect]

By making the suspension link an integrated structure,
The parallelism, mounting pitch, and centering accuracy of the pins at the connection between the suspension link and the link receiver are improved. Furthermore, the number of man-hours required for assembly and adjustment is significantly reduced.

By attaching the link receiver to the roof beam while supporting the link receiving beam of the vehicle roof beam from below, the weight of the vehicle is held by the entire suspension link receiving beam, improving structural strength and safety.

〔Example〕

In Figures 1 and 2, 1 is the monorail car body, 2 is the car body roof beam, 3 is the suspension link holder, 4 is the pin, 5 is the suspension link, 8 is the roof plate, 9 is the mounting bolt, and 21 is the joint beam. , 22 is the cross beam, 23 is the ceiling,
24 is a link receiving beam, 25 is a rain cover, 26 is a closing plate, 27 is a rubber seal, 28 is a ceiling lining, 29
is our board.

The overall structure of the monorail vehicle is similar to the conventional device shown in FIGS. 5 and 6.

The suspension link supports 3 are welded together on the left and right with joint beams 21, and the cross beams 22 are passed through the front and rear to form a strong block weld. All 4 parts of the pin 3 have an integrated structure, and when installing to the roof beam part 2 of the vehicle body, the interior and exterior (ceiling side, roof board side) are open so that the link holder 3 can pass through the center from the bottom. The link receiving beam 24 is attached to the body structure by being supported from below from the ceiling 23 side of the interior of the vehicle body. After installing the suspension link receiver 3, the outdoor opening is closed with a rain cover 25. In other words, the blocking plate 2 is placed in advance at a predetermined position of the integrated suspension link receiver 3.
6 is welded, and after installing the link holder 3, the roof plate 8
A rain cover 25 is attached to a rubber seal 27 fitted around the opening via a closing plate 26. Also, on the other hand,
Since the indoor opening is covered with the ceiling lining 28 after the link holder 3 is installed, the link holder 3 is covered with the closing plate 26 and the ceiling lining 2.
8 and is stored inside. Abutment plates 29 are attached to the mounting surface of the suspension link receiving beam 24 (at four locations each on the front and rear), and the structure is such that flatness can be achieved after the roof beam portion 2 is constructed.

The above-described link receiving structure ensures mechanical accuracy of the parallelism of the center of the pin 4, mounting pitch, centering, etc., and eliminates the need for adjustment work when engaging with the suspension link 5.

[Effect of idea]

(1) By making the suspension link receiver into an integrated structure, the precision of each part manufactured can be greatly improved, and the number of man-hours required for assembly and adjustment can be significantly reduced. Moreover, the mounting structure is strong and safe.

(2) The flatness of the bearing surface of the suspension link receiving beam allows for accurate parallelism of pin centers (4 locations per set of suspension links), mounting pitch, centering, etc. just by installing the suspension link receiver. Naturally secured.

(3) The suspension link receiver, which is integrated as a strong block, is installed so as to support the suspension link receiving beam on the roof beam of the vehicle body from below, so it is in a state of tight contact due to the load of the vehicle body, and the mounting bolt is also attached to the link. They only need to be able to withstand the weight of the bridge and fixation when the vehicle body rolls, and only a small number of bridges are required compared to the conventional method, and installation and rigging are also easier.
