Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides the above-mentioned Arlo This paper relates to an improvement of the suspension-type mole rail currently in use as an urban transportation system in which the vehicle body is suspended through a section.

Figures 1 and 2 show a conventional mole rail, and the track girder (
1) is made of steel and is formed into a box-shaped girder with an open center part on the lower surface, and running paths (2) (2'
), and the upper left and right walls are equipped with guideway walls (
3) (3') is provided.

The trolley (4) is a traveling drive device ([)] including a differential gear system.
, and the main lij machine (6) that drives the same device (5), the left and right running wheels (force (7')) rotatably attached to the traveling drive device (5), and the wheels installed on the front, rear, left and right sides of these wheels. The car body (9) is suspended from the bogie (4) via the suspension device (11) by a link-type suspension device (10), and the bogie ( 4
), and the vehicle body tilts in response to the centrifugal force when passing through a curve, which is advantageous in terms of increased speed when passing through a curve and ride comfort.

When the main motor (6) is driven, the running wheels (7) (
7') are driven at the same time, and the running wheels (71 (7') run forward or backward on the running path (2) (2). Also, the guide wheels (8) (8') respectively run on the guide road wall (2). 3)(
3') to guide the trolley (4) along the track. Vibration caused by the running of the vehicle body (9) is caused by the suspension system OD.
It is absorbed by the air spring used in

However, in the conventional mole rail, most of the bogies are housed within the track girder, which has a box-shaped cross section.
Although it has advantages in terms of weather resistance and resistance to the weather, on the other hand, the structure was rather complicated, and the construction cost, weight, and volume tended to increase.

The present invention was proposed in order to eliminate such drawbacks, and includes a track girder formed in the cross section of the mold, a running wheel suspended so as to grip the inside of the lower flange of the track girder, and its drive. A traveling bogie comprising a device, a guide wheel that clamps the web of the drive girder, and a stabilizing wheel for preventing the vehicle from tilting over 1Φ, which is disposed oppositely with a gap between the upper part of the web, and from the same bogie. The present invention relates to a mole rail characterized by comprising a suspended mole rail car body, and a cover for shielding space inside the track girder vertically installed closer to the car body than the track girder.

Since the present invention is configured as described above, the traveling bogie on which the mole rail car body is suspended by driving the running wheels by the motion device of the traveling bogie is formed on the cross section of the working die.
¥11. It runs forward or backward along the lower flange of the road girder. The guide wheels that hold the web of the track girder on the ridge receive the lateral force applied to the car body or the running bogie when passing through a curved road, and guide the Morseal car frame so that it runs along the track.

Stabilizing shafts for preventing over-inclination of the vehicle are placed opposite each other with a gap between the two parts of the web of the track girder, so that when passing through a curved track, the presence of the gap prevents the rotation of the bogie. The Morrail vehicle makes a pendulum movement around the center,
The vehicle body automatically tilts in response to centrifugal force, allowing passengers to
This offsets the force and improves riding comfort, and also reduces the lateral force applied to the running bogie due to the rear force of the inclined car body, reducing the lateral load on the track, and as a result, it is easier to pass through curves. Speed is improved.

1) In the present invention, the track girder is formed with a burr cross section, so the structure is simplified compared to the conventional track girder with a box-shaped cross section, and the amount of work and manufacturing cost is reduced.Furthermore, the present invention In this case, since the track girder internal space shielding cover is vertically installed closer to the vehicle body than the track girder, the present invention has many advantages, such as wind and snow being closed later and the soundproofing effect being improved. It is.

Hereinafter, a first embodiment will be described.

A +pA road girder made by FF, J++ is formed into a cross-section of a mold by connecting upper and lower flanges with a web. The girder height of the upper and lower flanges can be changed according to the requirements. The upper flange of the soft track girder (21) is formed to have a cross section of 1λ as shown in the fourth [K1] as required.
- can provide additional rigidity and strength.

At the upper part of the rotary shaft 11 of the lower flange of the track girder (21), there are two guideways (22) provided at the bottom of the web, and at the bottom of the web there are guideway walls (°):→( 2

Covers (24) from both sides of the twisted track girder (21) (24
A shovel is suspended close to the car body (2').

Running trolley (20 is a suspension frame (2 forces, running wheels 12R) (2

) is installed.

The suspension frame 127) has a structure in which both parts and the lower part of the platform 6) are integrated, and forms the main part of the truck, and suspends the vehicle body (25) via the suspension device (331).

The running wheels (28) (28') are located at the front and rear of the suspension frame η, are arranged as close as possible to the web of the track girder 121) and grip the inside of the lower flange, and rotate to the suspension frame (27I). can be attached to the guideway t22)
(22') so that the vehicle can travel forward or backward respectively.

The reduction drive device 09) is a gear device I! ! -, etc., is attached to the central part of one side of the suspension frame (27), is driven by the main electric motor, and simultaneously drives the front and rear running wheels.

Note that the speed reduction and drive device 4 can be further provided at the center of the other side of the suspension frame Qη.

One or two pairs of guide wheels Gυ (31') are provided in front or behind the travel @■ (28'), and are rotatably attached to the picture frame (5), and are mounted on the guide path wall v3) ( 2
Transfer three trains and guide the trolley (26) along the track. In addition, three (32') stabilizing shafts are provided at the upper left and right center of the suspension frame 172, respectively.

The web of the track girder eJ11 is sandwiched between the web of the track girder eJ11, and the track girder eJ11 can roll on the web of the track girder eJ11 when the vehicle body (4) is tilted. .

The two are the suspension system (suspension frame through the image, 27

Improve the ride comfort. In addition, the restoring force of the tilted car body reduces the lateral force applied to the bogie (2G), reducing the lateral load on the track, and as a result, the speed in curves can be improved.

Note that the gap δ is determined by the vehicle body inclination limit determined by the construction limit of the track and the like.

By changing the girder height of the track (21), it is possible to provide rigidity according to the span length, and by making the upper flange of the track a closed cross section as shown in Fig. 4, it is possible to provide rigidity according to the span length. Accordingly, folding strength can be imparted.

Furthermore, 1 is located closer to the car body f2', +) than the track girder (2I).
