System for dynamic control of the rolling of the guide roller(s) for an assembly for guiding a vehicle along at least one rail

摘要

A system of dynamic control of rolling on at least one guide rail for a guidance system of a vehicle along at least one guide rail, composed of at least one roller or at least one pair of guide rollers rolling along this guide rail, is characterized in that it incorporates a vibrational sensor located near at least one roller or at least one pair of guide rollers and a proximity sensor, and in that the signals transmitted by these sensors, or the circuits in which they are placed, are continually analyzed to establish a commencement of guidance failure, a guidance failure, a limit of wearing of or damage to the roller(s) or their tires. This invention is of interest to manufacturers of vehicles guided along at least one rail.

主权项

1. A guidance system of a ground vehicle along at least one guide rail, the guidance system being endowed with a dynamic monitoring system for dynamic control of contact with the rail, the guidance system comprising of at least one roller or at least one pair of guide rollers rolling along at least one guide rail, the guidance system having a first state in which at least one roller or at least one pair of rollers rolls on at least one guide rail via a tire, a rolling surface or a rolling periphery in a normal guidance situation, and a second state in which at least one of the rollers, or a protruding surface of a mounting of at least one of the rollers, rolls on or rubs against the guide rail or the road surface in a derailed situation, characterized in that:
the vibrational characteristics of the part of the roller or rollers in normal rolling contact with the guide rail during a normal guidance situation, and the vibrational characteristics of the area in contact with the guide rail or the road surface in a derailed situation, are different; and the dynamic monitoring system incorporates a vibrational sensor located near at least one roller or at least one pair of guide rollers and a proximity sensor; and the dynamic monitoring system incorporates a unit for processing and analyzing signals from the sensors or from circuits in which the sensors are placed, in order to analyze the signals and continually establish whether the signals from the vibrational sensor and the signals from the proximity sensor exceed a first warning threshold and a second warning threshold, respectively, such that a derailment alarm is triggered if the first and second thresholds are exceeded.
