Definitions
- the invention relates to a system for dynamically controlling the rolling of one or more rolling elements for a vehicle guidance assembly along at least one rail.
- a guide assembly by rolling along at least one rail including ground for a road vehicle, including a public transport vehicle.
- this dynamic control system combines the generation and recognition of a vibratory state and the indication of a difference in elevation of the rolling element or elements of the guide assembly with respect to the (x) rail (s). ) to provide information on the risk and condition of derailment and wear of these rolling elements or the bandage thereof.
- Such detection can result from a measurement or recognition of a vibratory state and an inductive measurement from sensors located on the guide assembly to indicate any failure of the guidance to avoid accidents following a derailment in any case to minimize the consequences of a derailment. This is to alert on a potential derailment that is to say the beginning of a clearance to proceed to security or safety actions.
- the present invention relates in particular, but not exclusively to the particular case of guidance by two inclined rollers rolling on the inclined tracks of a guide rail as shown in the figures. These rollers may each have a shank.
- Guiding is normal and safe when the rollers enclose the rail.
- the part of the roller which is in contact with the rail is relatively flexible material, for example rubber or polyurethane. But in all cases, this part of the roller does not have the same stiffness characteristics as the sill it is in the same material as this one or it is in another material.
- the pebbles have one of the preferred modes embodiment of the invention because it is aimed at all types of rollers or guide wheels.
- guiding devices which comprise a rotating fixed casing connected to the support of the roller or rollers and protruding relative to the rolling track of the rollers.
- the vehicle equipped with the guide assembly still follows its trajectory, but the derailment is to be expected.
- the part of the guide which is in contact with the rail is made of steel. We thus have an iron-on-iron contact. Then, if the rollers leave the rail, as the chins or the housing are prominent that is to say protruding from them, they will come into contact with the roadway. Again, the vibratory signature is different.
- the present invention constitutes a suitable solution which makes it possible to satisfy this need and, in addition, to detect the limit of wear or the deterioration of the tire of the guide rollers.
- the system for dynamically controlling the rolling on the guide rail and the contact with this rail makes it possible to ensure a constant and real-time monitoring of the rolling of the wheel (s) or guide wheels on the guide rail with a view to to emit an alarm at the slightest deviation or modification of elevation or trajectory of this or these rollers and more generally of the guide assembly of which they are part.
- a warning signal warns the monitoring and safety system and the driver of the vehicle that acts accordingly by applying the safety instructions depending on the severity of the incident.
- This same warning signal can also trigger the actuation of safety devices, causing for example the stopping of the vehicle or the engagement of an active device for anti-derailment or re-rigging.
- the system according to the invention also makes it possible to detect the wear or the deterioration of the tire of the rollers constituting the rolling means of the guide assembly on the rail. This ensures safety and maintenance monitoring for the replacement of this bandage.
- the object of the invention is twofold. It allows first to ensure a constant monitoring of the proper operation of the guidance and to prevent early clearance. It then allows preventative maintenance by detecting normal or excessive wear of the roller bandage.
- the invention relates to a system for dynamically controlling the contact with the rail of the rolling means of a guide assembly of a road vehicle by displacement along the less a guide rail especially on the ground.
- Such a system must be able to operate in all normal situations of movement or stopping of the vehicle, that is to say in both directions of travel, over the entire range of authorized speeds, when switching points, crossings or expansion joints, when driving in a tight corner, during braking, etc. Moreover, since the non-detection of a deguidage is a particularly feared event, the system failure rate must be as low as possible.
- this system for dynamically controlling the guiding and the contact with the rail comprises at least one sensor with a means of generating a vibratory signal associated with a means of recognizing a vibratory regime which translates a critical state of guiding or wear of the roller (s) or bandage thereof and a proximity sensor that accounts for the elevation of the at least one roller or guide assembly relative to the rail.
- the combined analysis of the signals of these two sensors makes it possible to conclude that a derailment or a deguidage.
- the alert of the vibratory sensor alone signals either a sensor fault or a faulty tire.
- the proximity sensor only alert indicates a fault of this sensor. The existence of the two warnings above leads to the conclusion of a derailment.
- the detection means ensuring the generation of a vibratory signal preferably comprises at least one accelerometer integral with the mechanical element for taking up each pair of guide rollers.
- the output signal of the accelerometer or each accelerometer is processed and analyzed for example in frequencies and a comparison is made to determine information on the state of good operation of the guide assembly.
- the proximity sensor is preferably inductive in nature. It comprises an inductive sensor which monitors the dimension between a fixed reference on the guide assembly, for example the lower take-up axis of the guide rollers and the top of the guide rail. This dimension is practically invariable as long as there is no deguidage. It can be reduced slightly over time with the normal wear of the roller bandage. This eliminates the mechanics of guidance, that of the vehicle and the infrastructure.
- the outputs of the Acceleration Sensors and Inductive Proximity Sensor are easily accessible, and connected by connectors, for quick and easy maintenance.
- These sensors are particularly resistant to variations in temperature, wear, shock and vibration, which ensures the reliability of the dynamic control system of the invention for a long time.
- This device for dynamic control of the rail contact has many other advantages, among which we can mention those according to which:
- the system of dynamic control of rolling and rail contact can provide other information except those on the derailment. It can provide, for example, signals whose shape and frequency indicate the wear of guide elements or their bandage or a failure thereof.

- a dynamic control system 1 is used on a guide assembly 2 of any vehicle along at least one guide rail 3, in particular on the ground 4, in which it there is at least one vibratory sensor 5, for example an accelerometer 6, and at least one proximity sensor 7, for example an inductive sensor 8, carried or fixed on this guide assembly 2 in the vicinity of at least one roller 9 or at least one pair of guide rollers 9 and the signals of these sensors 5, 7 are used to determine a clearance, the derailment state and the simple wear of the tire of the guide rollers 9.
- the signals emanating from each vibratory sensor 5 are processed by analyzing them in frequencies and the level of the signal of the proximity sensor 7 is compared with a distance reference to determine whether the signals of the vibratory sensor (s) translate a deterioration or a wear of the guide rollers 9 or a derailment if there is concomitance of the two alarms provided by the detection assemblies.
- the dynamic control system 1 of the invention is described here mounted on a guide assembly 2 provided for a land vehicle guided along a central rail 3, in particular on the ground 4.
- this system 1 is not specific to this type of guide assembly and it can be adapted and used with any guide system by contact on at least one guide rail.
- each axle or axle frame 10 of the guided vehicle uses a guide assembly 2 comprising two pairs of guide rollers 9, namely a pair 1 1 of guide rollers 12 and 13 located forwardly in the direction of travel, and a pair 14 of follower rollers 15 and 16 located aft in the direction of travel, which allows the vehicle to flow in both directions.
- a guide assembly 2 comprising two pairs of guide rollers 9, namely a pair 1 1 of guide rollers 12 and 13 located forwardly in the direction of travel, and a pair 14 of follower rollers 15 and 16 located aft in the direction of travel, which allows the vehicle to flow in both directions.

- This pair 1 1, 14 of guide rollers 9 follows the guide rail 3 by rolling on the side edges 20 and 21 used as a track and directs the axle or the axle frame 10 in the manner of a trailer drawbar .
- All lateral forces for example caused by wind or centrifugal force, are taken up by the tires 22 and 23 relating to the axle frame 10 and to the vehicle. Only the forces necessary for the orientation of the axle-frame 10 are taken up by the guide assembly 2.
- rollers 9 and the lateral edges 20 and 21 in chamfer of the guide rail 3 are inclined at 45 °, which makes it possible to reduce the vertical load on the rollers 9 and to transmit the forces on the guide rail 3 by rolling rollers. 9 and not by friction of the chins 17 on the guide rail 3.
- the rollers 9 often have a rolling band such as 24 of flexible material by which they are and normally remain in contact with the guide rail 3 and which ensures a soft contact with it.
- the disadvantage of this material is that it wears with the rolling time, which requires its replacement.
- this part is also made of steel, but of a suitable shape to be more flexible radially and therefore less stiff than the chin.
- the guide assembly 2 is furthermore composed of a sliding coulter before said stone-thrower, of an oblique-arm support structure 26 and 27, of a spring 28 ensuring a permanent downward stress, of two pivoting axes 29 and 30 for its lifting, pads such as 31 and 32 for the rollers, as well as various electrical connections 33, 34 and 35 return of the supply current of the vehicle with electrical energy.

- the frequency signature or the signal spectrum of the vibratory sensor 5 has a given shape. If the roller 9 or a part thereof rolls or rubs on the rail 3, the contact iron on iron generates a different vibration and vibratory signature for example in frequencies of the vibratory sensor 5, that is to say, its decomposition in frequency, has a different form and content. It is thus possible by comparison, to detect any problem at least one of the rollers 9, for example a wear of its bandage 24 of flexible material or a relieving.
- a proximity sensor 7 is used in the form of, for example, the proximity inductive sensor 8 which permanently indicates its distance, in particular vertical distance from to a reference surface.
- This proximity sensor 7 is mounted on the guide assembly 2 in a place which allows it to give a slight interference indication of the distance relative to a reference surface, in particular its distance from the upper surface of the guide rail 3 which is hereinafter called H-side and identified in FIG.

- the two levels are compared in a differentiation module RMSB1 B2.
- an ALACC accelerometric alert is triggered.
- the adjacent BAMF medium frequency analysis block is also powered by the signal from the measured SGAME vibrating sensor (s). It presents a path consisting of a high frequency medium-frequency bandpass filter F3 in the B3 range of 150-1000Hz followed by a module for measuring the level of the RMSB3 medium-frequency upper-frequency voltage. This level is compared to a threshold S in a comparator COMB3. This threshold S differs depending on whether one is above or below a minimum vehicle speed Vmin for example 15 km / h. An encoder assigns a value different from the threshold S if the vehicle speed is less than or greater than Vmin.
- the comparator COMB3 emits an alarm signal if the level of the effective voltage of the signal B3 is greater than the value of the threshold S.
