Definitions

  • the present invention relates to a method for centering the steerable axles of a bogie.
  • the method for centering the steerable axles of a bogie of the invention applies more particularly to a bogie with two steerable axles.
  • Such bogies include, for example, a chassis connected to each axle by means of two axle boxes and a primary suspension formed from deformable elastic blocks.
  • the orientation of the axles is achieved by means of jacks controlled by a track sensor. Under the action of these cylinders, the elastic primary suspensions are deformed to allow the axle to assume a radial position in a track curve. Axle orientation is usually accomplished by flexible suspension. Stability of the axle in a straight line is then ensured by means other than flexible suspensions.
  • the advantage of bogies with steerable axles, more particularly for the metro and tramway networks, is to reduce the nuisance caused by the "iron” equipment, namely: squealing, wear of rails and wheels, as well as solidian vibrations transmitted to buildings.
  • the method for centering the steerable axles of a bogie of the invention is characterized in that, at the entrance to a track curve, at least one of the axles is oriented towards the center of the curve and in that each wheel is positioned transversely to the track so that each of the wheels is at the same distance from its rail.
  • the method of centering the steerable axles of a bogie of the invention is characterized in that, in a track curve, at least one of the axles is arranged radially to the curved and is centered transversely to the two lines of rail in the track.
  • the method of centering the steerable axles of a bogie of the invention is characterized in that a signal whose value would not fall within a predefined range of values is considered to be invalid , the resulting signal then being extrapolated from a previous value and the only signal remaining valid.
  • the method for centering the steerable axles of a bogie of the invention is characterized in that, if only a valid signal exists, it is also invalidated, the last resulting signal being then considered invariant until the two signals have become valid again.
  • the method for centering the steerable axles of a bogie is characterized in that, following a failure of the control or power devices, the bogie's axle control is neutralized by an internal detection device by eliminating all power controls so that the vehicle returns to a conventional configuration.
  • the particularity of the method for centering the steerable axles of a bogie according to the invention lies in the fact that the servo-control described below makes it possible to center the axle in the track.
  • An advantage of the method for centering the steerable axles of a bogie according to the invention is that it applies to any bogie with steerable axles of the prior art having at least one lane detector.
  • An advantage of the bogie with steerable axles according to the invention is therefore to provide positive security for the stability function of the bogie with steerable axles.
  • Another advantage of the method for centering the steerable axles of a bogie according to the invention lies in the fact that the vehicles using the steerable bogies of the invention can be driven on tracks which do not require any particular adaptation.
  • the orientation of the axles of the bogie of the invention is achieved by servo-control.
  • the servo-control operates permanently on a track in alignment or when crossing curves.
  • Sensors 1-4 equip the axles 5 and 6 and each have the function of detecting the axis of magnetic symmetry of the rail 7 or 8 with which it is associated.
  • Each sensor is arranged longitudinally in front of or behind the axis of the axle.
  • the sensors are for example of the type described in French application N ° 90.04436.
  • Each active sensor delivers a signal which is a function of the offset between its position and the magnetic axis of the rail. However, these signals are not measured vertically but in front of the axles. The signals delivered are summed so as to have, for each axle, a signal resulting from the offset of the axle relative to the longitudinal axis of the track.
  • the resulting signal constitutes the disturbance added to a zero setpoint in the external loop of a servo in position which may include one or more other internal loops.
  • the output signal from the servo circuit controls a set of two cylinders 9,10; 11.12; 13.14 and 15.16 per axle. These cylinders are arranged approximately longitudinally in the bogie and control the orientation of the axle by bearing on the chassis 17, 18 of bogie. The torque exerted by the jacks acts in the favorable direction to reduce the signal resulting from the set point produced from each of the two axle sensors.
  • the objective sought is to keep the axles as close as possible to the center of the track, while eliminating the influence of the variations in the spacing of the rails, by seeking to center the axles laterally at the level of the sensors, that is to say , in front of their own axis of rotation.
  • the axle orientation control device described above is an active system. Its implementation requires at least one power source 19.20, for example a hydraulic source.
  • the servo In the event of failure of the control or power devices, the servo is neutralized by an internal detection device by eliminating all power commands. The vehicle is then in a conventional configuration. Control is therefore no longer ensured and the vehicle's security level is that of a conventional vehicle.
  • the bogie with steerable axles is fitted with relatively stiff primary suspensions to ensure sufficient stability of the vehicle at maximum commercial speed.
  • each sensor delivers a signal whose value is compared to a predefined range of values. A value which is not included in the predefined range of values is considered invalid. The resulting signal is then extrapolated from a previous value and the only signal remaining valid. This situation is encountered in particular when passing over singular points such as switches and crossings. This procedure is applied until both signals have become valid again.
  • the bogie with orientable axles comprises four sensors arranged on the side external to the axles of the bogie.
  • the bogie with steerable axles has a set of two active sensors for each direction of travel.
  • the sensors therefore make it possible to obtain a single resulting signal.
  • This unique resulting signal is associated with the first of the two axles disposed in the direction of travel and is used to drive the two axles.
  • the vehicle axles can either be conventional axles, with wheels fixed on the same axis, or axles with independent wheels, using a differential.
  • Vehicles may use the safety system and procedure of the invention only for part of their bogies with steerable axles.
  • the extreme axles of a vehicle are equipped for both directions of travel. We then have a single resulting signal associated with the driving axle to drive four axles. To do this and taking into account the real values of the dimensions that come into play, namely: distance between bogie, length of connection curves, speed, it is necessary to develop a signal out of phase with the first, to control the second bogie.
