Bellows passage connector for articulated passenger vehicle - with support hoop hanged on triangular support frame and braced by elastic ties

摘要

The rear of the leading car has a triangular frame mounted horizontally at its rear roof edge, with its apex pointing towards the trailing car. An inverted U-shaped frame is pivotted from the apex and forms the connecting link for the two bellows passages connected to the two cars. Elastic ties are secured between the apex and the top roof edge of the trailing car, and are angled at nearly 90 deg. to each other, as are the arms of the triangular frame. The ties are secured on the apex at separate points behind the pivot point of the U-frame. The system enables the vehicles to flex horizontally as well as vertically when travelling over bumps.
