Apparatus for detecting deflation of a guide wheel tire of a transportation vehicle

摘要

A transportation vehicle for a transit system has a supporting structure provided with wheels moving on parallel tracks and inflated tires in rolling contact with stationary guide bars for guiding the structure. An apparatus for providing an indication of deflated or flat rubber tire is provided on the roadway. It detects lateral offset of the support structure with respect to the tracks from a set position responsive to deflation of one tire. The sensors are connected to a circuit which provides an alarm when the amount of offset exceeds a predetermined value.
