DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body connection device, and more particularly to a vehicle body connection device suitable for a high-speed driving vehicle such as a linear motor car.

[0002]

2. Description of the Related Art Conventionally, the outer periphery of a connecting passage of a railway vehicle is covered with a bellows-shaped connecting hood for safety of passers-by. That is, as shown in FIG.
The bellows-shaped connecting hoods are fixedly held to the vehicle end face by mounting brackets so as to surround the connecting portion passages 1a and 21b to form a closed space.

[0003]

However, in the conventional connecting hood, as shown in the drawing, the connecting hood portion has a vehicle 21a,
The height is lower than the height of 21b, so that a recessed space is formed therein, so that air flows in at the time of traveling and generates air noise, which is a cause of noise. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to provide a vehicle body connection device capable of preventing generation of air noise without forming a recessed space in a connecting portion of the vehicle body.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to an iron plate provided so as to protrude at the same height as an outer peripheral surface of a vehicle body along a peripheral edge of the vehicle body, and to an iron plate provided between mutually opposed iron plates of a vehicle body connected to each other. A band-shaped bond magnet provided so as to cover the gap between the iron plates by being attracted to the inner surfaces of the two iron plates by magnetic force, and attached between the inner surface of the bond magnet and the two vehicle body ends, between the two vehicle body ends. And an expansion joint for forming a closed space. The expansion joint is made of rubber.

[0005]

According to the present invention, an iron plate protrudes from the end of a vehicle body along the periphery thereof on the same plane as the outer peripheral surface of the vehicle body, and a band-like bond magnet is attracted to the inner surface of the front and rear vehicle bodies by magnetic force. Furthermore, an expansion joint is provided between the inner surface of the magnet and the end of the vehicle body to form a closed space so that the vehicle body is connected.The outer periphery of the vehicle body connection portion is the same as the vehicle body height, and the recessed space is Since it disappears, generation of air noise can be prevented.

[0006]

1 is a view for explaining a vehicle body connection device according to the present invention. FIG. 1 (a) is a side sectional view, FIG. 1 (b) is a plan view, and FIG.
(C) is a front sectional view. In the figure, reference numerals 1a and 1b denote vehicle bodies, 2
a and 2b are iron plates, 3 is a bond magnet, and 4 is an expansion joint. Iron plates 2a, 2b are provided at the ends of the vehicle bodies 1a, 1b along the edges thereof so as to protrude on the same plane as the vehicle body surface. A band-like bonded magnet 3 is provided on the inner surfaces of the iron plates 2a and 2b by magnetic attraction. The bond magnet 3 is made of a mixture of plastic or rubber and magnetic powder. An expansion joint 4 made of rubber or the like is provided on the inner surface of the bond magnet 3 between the vehicle bodies so as to surround the passage between the vehicle bodies. Since the magnet 3 is attracted to the iron plates 2a and 2b by magnetic force, when the distance between the vehicle bodies 1a and 1b changes due to a curve or the like, a slip occurs between the iron plates 2a and 2b and the bond magnet 3 to cause the gap. Can absorb changes. Also,
The iron powder and the magnetic powder generated by the friction between the iron plate and the bonded magnet are adsorbed by the magnet 3 and do not scatter around. Further, since the outer surface formed by the iron plates 2a, 2b and the magnet 3 is at the same height as the vehicle bodies 1a, 1b, there is no space into which an air flow flows, and the generation of air noise by the conventional connecting hood occurs. Never.

The vehicle body according to the present invention has a structure mounted on a bogie as shown in FIG. 2, for example. That is, FIG.
As shown in the plan view of FIG. 2A and the side view of FIG. 2B, the trucks 10a and 10b are connected to each other by a coupler 13, and shock absorbers 11a and 11b are provided on both sides of the end of the truck. An elastic body 1 made of rubber or the like is provided on one of the shock absorbers 11a.
2, the cushioning device 11b opposed thereto is provided with a concave portion in which the elastic body 12 is fitted.
The mutual angle change of 10b is permitted by the coupler 13, and is absorbed by the expansion and contraction of the elastic body 12, so that these carts are connected without any gap. The vehicle body is placed on such a trolley and connected by a connecting device as shown in FIG.

[0008]

As described above, according to the present invention, it is possible to prevent the generation of air noise due to the inflow of air flow as a result, without the formation of a recessed space in the connection portion between the vehicle bodies. .
