Device to maintain a trajectory of a guided vehicle in the event of derailment and/or failure of guidance

摘要

A device to be fitted to a guided vehicle moving on a track having a guide rail and two side rails parallel to and on each side of the guide rail maintains a trajectory of the vehicle upon derailment. The vehicle includes a guidance unit having guide wheels to be supported on the guide rail. The device includes a bar to be fixed to the guidance unit transverse to the track. The bar has a length L between a distance D mutually separating the side rails minus the width C of the head of the guide rail and the distance D mutually separating side rails, i.e. D−C

1. In a system having a track including at least one guide rail having a head with a width C and two side rails each disposed parallel to the guide rail and positioned on a respective side of the guide rail and mutually separated by a distance D, and a guided vehicle including a guidance unit having guide wheels to be supported on the guide rail, a device to be fitted to the guided vehicle for maintaining a trajectory of the guided vehicle moving on the track, the trajectory maintaining device comprising:
a. a bar configured to be fixed to the guidance unit so as to be transverse to the track, said bar having length L dimensioned between the distance D mutually separating the side rails minus the width C of the head of said guide rail and the distance D mutually separating the side rails: D−C
