At the opposite end of the lateral frame 123, the upper / lower frame 124 is configured to be connected to the lateral frame 123 via the hinge H2.

Further, a connection frame 125 is formed at the opposite end of the up / down direction frame 124.

When the connection frame 125 is fixed to the rear truck with respect to one of the wagons, it is fixed to the front wagons provided in the other wagons adjacent to the wagon, so that the wagons can be continuously arranged.

3 and 5, axle boxes (not shown) functioning to support and protect the ends of the axle are provided below the side frames 110, respectively.

In the axle box, the linear motor hanger bar 130 is fastened by fastening means such as a bolt.

At this time, as shown in the accompanying drawings, the axle boxes are formed by two for one side frame 110, so that a total of four axle boxes can be formed.

Specifically, the axle box may be directly coupled to the side frame 120, but may be connected via a separate auxiliary frame or the like.

The main function of the linear motor hanger bar 130 is to allow the linear motor 140 to be fixed to the carriage 100 via the motor connecting portion 141.

More specifically, the configuration in which the linear motor hanger bar 130 is connected to the axle box is shown in FIG. 7 of the accompanying drawings.

According to Figure 7 of the accompanying drawings,

The linear motor hanger bar 130 has a structure for connecting a pair of axle boxes, and has a hanger bar end 130a formed at the end thereof with a through hole penetrating in the traveling direction of the bogie.

That is, the end portion 130a of the hanger bar 130 is connected to the one side of the bracket 131, and a hole having a predetermined size for inserting the hanger bar end 130a is formed on one side of the bracket 131 .

A rubber bushing 132 passing through the through hole of the hanger bar end portion 130a passes through the through hole and is fastened to one surface of the bracket 131 through fastening means such as bolts at both ends thereof. Also, the connection between the bracket 131 and the axle box can be achieved through the fastening means.

The linear motor 140 has a structure such that it is developed on a plane cut along the axis of the induction motor. The linear motor 140 is composed of a stator and a reaction rail, and generates a linear driving force in the rail direction.

As an example in which the linear motor 140 is applied to a train, since there is a magnetic levitation train, the function of the linear motor 140 in the present invention is omitted. However, the linear motor 140 drives the motor so as to enable a parallel stop when the vehicle is stopped by the bogie according to the present invention.

The linear motor 140 is fastened and coupled to the upper surface of the end portion through a fastening means such as a bolt or the like by a motor connecting portion 141. The motor connecting portion 141 is fixed to the linear motor hanger bar 130, So that the hanger bar 130 and the linear motor 140 can be connected.

The motor connecting portion 141 will be described with reference to an enlarged view of FIG.
