Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bogie, a bogie structure, and a linear motor support structure in which a central passage in a train of a railway as a public transportation system has an ultralow floor.

[0002] The present invention also relates to a method of laying a track for running an iron-wheel linear train of a 100% ultra-low floor vehicle.

[0003]

2. Description of the Related Art Conventionally, iron-wheel linear trains have been put to practical use as subways and elevated railways. In the case of a subway or elevated railway,
Since it is not necessary to travel on the road surface and the vehicle floor surface of the train does not need to be as high as 350 mm or less as required for road surface transportation, a dedicated platform can be provided. In the case of an ordinary train, a dedicated platform can be provided, so that there is no height restriction on the vehicle floor. For this reason, the conventional iron-wheel linear electric train has an axle connecting left and right wheels, and adopts a bogie configuration in which a linear motor is loaded using a space between wheels of the bogie on the axle.

[0004]

SUMMARY OF THE INVENTION In the case of public road traffic,
Barrier-free electric stops (train stops) that pedestrians can easily access on the road are required, and the height of the platform is also required to be reduced to about 300 mm. In order to cope with such a platform, steps are usually provided at the entrance of the train.

However, since these vehicles are unacceptable as barrier-free vehicles in response to the recent aging era and considering that they can be easily used by persons with mobility impairment, various types of barrier-free vehicles are required. Measures have been taken. For example, a countermeasure is to equip a lift for getting on and off or to make a low-floor vehicle structure of about 70% in which the area around the entrance is lowered.

However, the former is not practical because it has a problem that the lift equipment takes up a large occupied area and it takes time to get on and off. In the latter case, since the toll collection is performed near the driver, at least the floor of the central aisle must have a flat structure so that passengers can pay at the exit without trouble. There is.

[0007] As described above, as long as the toll collection is under the control of the driver, there is a problem in the partial low-floor structure in practical use of the iron-wheel linear electric train as a tram, and a 100% ultra-low-floor vehicle Development was required.

[0008] As in the past, the tram has a history of prosperity and has declined, so that in a large city where the road surface is taken by car and mass transportation is required, the transportation is replaced by a subway or a monorail running on an elevated track. Migrating.

[0009] On the other hand, even in local cities, there are severe road conditions in planning transportation, and train traffic is beginning to be reviewed from the viewpoint of being friendly to the global environment and having energy saving properties. The routes required in these existing cities are low-medium-volume transports suitable for the number of users and low-cost road transport.

However, in consideration of recent urban traffic conditions, even a tram travels basically on the road surface, but travels on an underground track or an elevated line in a city center where only an underground or elevated line is available. In the suburbs, it is often advantageous to plan a variety of routes, such as running on dedicated tracks.

In such a case, from underground to the road surface,
Alternatively, a vertical movement of moving from a road surface to an overhead line occurs. For this reason, in an adhesive drive system using the adhesive force between wheels and rails as in a general train, it is not possible to climb a severe gradient of a route. On the other hand, it is necessary to prepare a wide place to reduce the slope.

[0012] To solve this problem, a non-adhesive driving type train that can cope with a steep slope can be considered. At present, there are iron-wheel linear trains and floating linear trains as trains using this non-adhesive drive system. The former is thought of mainly on the subway, and the latter is thought of on the elevated line, but neither is suitable for road traffic. In addition, in the age of aging, if the road transport system allows anyone, especially those with weak traffic, to easily get on and off, the floor will be low and the floor can be moved from the passenger seat to the driver's cab where the fee is paid. It is necessary to realize a 100% ultra-low floor vehicle.

The present invention has been made in view of such a conventional technical problem. When an iron-wheel linear electric train is selected as a 100% ultra-low-floor vehicle suitable for an electric train running mainly on a road surface, the present invention is applied to such a case. A truck with a loadable structure, a truck structure,
It is an object to provide a linear motor support structure.

Another object of the present invention is to provide a track laying method for laying a track having a structure that enables a 100% ultra-low-floor vehicle to travel on a road surface of an iron-wheel linear electric train.
