At this time, the direction is switched by the hinge 22 of the vehicle beam 21 and the hinge hole 23 of the frame 11.

또한 뒤에 있는 다른 대차의 휠은 전기한 제 2,3휠(14)(15)의 방향과 반대되는 방향의 레일(30)을 따라 이동함으로써 전기한 바와 같은 동일한 과정을 통해 경전철이 레일의 진행 방향에 대해 90°로 꺽여진 상태로 위치하게 된다.In addition, the wheel of the other bogie behind moves along the rail 30 in a direction opposite to the direction of the second and third wheels 14 and 15 described above. It will be positioned at an angle of 90 ° to.

그리고 분기된 것을 ""한 형태로 할 경우에는 다시 처음과 같이 레일의 방향과 같은 방향을 유지하게 된다.And the branching " "When you do one form, you keep the same direction as the rails again, like the first time."

이 상에서 살펴 본 바와 같이 본 발명은 자량빔에 구비된 힌지와 프레임에 형성된 한지공을 이용하여 레일의 방향변화에 따라 소정 각도로 대차가 회전 가능하게 구비함으로써 객실을 레일방향에 대해 직각으로 변경시키고자 할 경우에 용이하게 할 수 있도록 한 이점이 있다.As described above, the present invention uses a hinge provided in the self-contained beam and a Hanji ball formed in the frame so that the bogie is rotatable at a predetermined angle in accordance with the change in the direction of the rail, thereby changing the cabin perpendicular to the rail direction. There is an advantage to facilitate the case.
