Definitions

  • the invention relates to a novel drive wheelset and, more particularly, to a single-axle wheelset with movable independent drive wheels, for a railway vehicle, that can be used on different gauges, with direct coupling between each drive motor and the driven wheel.
  • the invention is applicable to TALGO® wheelsets of variable gauge, or others of similar design.
  • TALGO® wheelsets consist of a pair of wheels, each one of them fixed on a short axle housed via its ends in separate bearings positioned one on the inside and the other on the outside with respect to the wheel and movable by sliding with respect to the frame of the wheelset in a direction perpendicular to the direction of travel of the train. These wheelsets are incorporated in the connection between two railcars.
  • the present system is an additional development of the work done by the applicant in the field of the construction of rolling-stock for travelling at high speed and equipped with movable independent wheels so that it can be adapted to different gauges.
  • Patent FR-A-1 558 329 of the applicant in which a description is given of a single-axle bogie with variable separation between the wheels, which solves the problem of it being possible to use one and the same bogie for travel on two different gauges, for example the gauge usually found in Spain and the gauge usually found in France and other European countries.
  • the spread drive applied to single-axle railway wheelsets equipped with independent wheels comprises, for each wheel, an electric drive motor associated with each wheel that transmits its actuation indirectly to the associated wheel, i.e. with the intervention, in addition to the corresponding transmission shaft, of an assembly of a gearwheel (integral with said transmission shaft) and ring gear (integral with the axle of the wheel in question).
  • a gearwheel integral with said transmission shaft
  • ring gear integral with the axle of the wheel in question.
  • Said gearwheel may be a bevel gear and said ring gear may be a crown wheel that meshes directly with the gearwheel and is mounted on the inside face of the wheel, with the result that the drive developed by the motor is applied to the inside end of the wheel axle.
  • the gearwheel is a spur pinion and the ring gear is a spur crown that meshes with the gearwheel via an intermediate spur wheel and is mounted on the outside face of the wheel, with the result that the drive developed by the motor is applied to the outside end of the wheel axle.
  • the present invention offers a system for direct coupling of an electric drive motor to a movable independent drive wheel, eliminating the speed-reducing and/or transmission mechanisms customary in this type of drive, which system is characterized by the electric drive motor for actuating its associated wheel being mounted directly in a coaxial position with respect to the geometric axis of the axle carrying the wheel, in an extension of said axle and towards the inside of the railway vehicle, such that a TALGO®-type wheelset of the kind to which the invention relates will be formed by independent separate wheels, each one of these mounted on a short axle supported in rotation, in turn, via its ends, in a pair of bearings that can move relative to the frame of the wheelset in a direction transverse to the direction of travel of the train, it being possible to immobilize said bearings by means of at least one locking bolt (in a manner similar to how this is achieved in the TALGO system with movable independent wheels) in selected positions in accordance with the gauge, each drive motor being mounted at the inner end of said
  • Said short, telescopic transmission shaft is in a retracted position, housed completely inside an axial cavity defined in the rotor of the drive motor when the wheelset is adapted in order to run on a narrower gauge, whilst it is in an extended position, partially outside the above-mentioned cavity of said rotor when said wheelset is adapted in order to run on a wider gauge.
  • This spread-drive system with direct coupling between drive motor and wheel may be mounted on the two types of TALGO® wheelset currently in use, in the first of which the frame has the general form of a yoke, with the wheels housed in the inverted U-shaped cavities of the frame on which the elastic suspension elements of the car body are mounted, and in the second of which the frame of the wheelset is flat, defining a substantially rectangular framework with the wheels arranged near its ends. For this, it is necessary only to vary the mounting configuration in order to fix the electric motors to said frame of the wheelset.
  • 1 generally indicates a wheelset of a type to which the invention relates, consisting, in this case, of a frame 2, substantially in the form of a yoke, on the end upper platforms 3, 3' of which the suspension elements (not shown) of the railway car body are intended to be mounted.
  • this wheelset 1 has an independent rolling assembly consisting of a wheel 4 (4'), an axle 5 (5') and respective outer and inner bearings 6a, 6b (6a', 6b').
  • Each one of said rolling assemblies is of the type that can be moved with respect to the frame 2 of the wheelset 1 in a direction transverse to the direction of travel of the railway vehicle, and the fixed operating positions of each one of said rolling assemblies with respect to said frame 2 are secured in the usual manner in wheelsets of this type by means of vertically movable bolts (not shown).
  • Fig. 1 shows the arrangement of the two drive motors 7, very close together and one on either side of the central longitudinal plane of the railway vehicle, each one of said motors consisting of an outer stator 8, 8' integral with the frame 2 of the wheelset 1 and a rotor 9, 9' mounted rotatably inside said stator 8, 8 '.
  • This rotor 9, 9' has a special configuration, with an axial cavity 20 of large diameter (see Figs.
  • FIG. 2a this shows, on a larger scale, a detailed view, in partial section, of the rolling assembly 4, 5 and 6a, 6b of the right-hand side of Fig. 1.
  • the elements shown in this figure, which are common with those of Fig. 1, have the same reference numerals as in that figure.
  • FIG. 2a shows the configuration of a rolling assembly that comprises a wheel 4 mounted on an axle 5 supported rotatably in outer and inner bearings 6a, 6b such that said assembly can move by sliding on the frame 2 of the wheelset in a direction transverse to the direction of travel of the train, the bearing 6b being shown in partial section in order to illustrate the installation bearings 12 of the axle 5 that support the inner end 11 of the latter, on whose outer face is mounted, at 16, for example by means of screws, a universal joint 14' integral with one end of the telescopic transmission shaft 10, the other end of which, provided with another universal joint 14, is secured at 15 to the back of the cavity 20 defined inside the rotor 9 of an electric drive motor 7 whose stator 8 is secured to the frame 2 of the wheelset 1 by any known means (not shown).
  • the rolling assembly is located in the position in which the wheel 4 is further away from the central plane of the railway vehicle, i.e. that which would correspond to a wider gauge like that customary in the Spanish National Network.
  • the telescopic transmission shaft 10 is extended, housed only partially inside the rotor 9.
  • Fig. 3 which is a diagrammatic plan view of a wheelset 100 with a flat frame 200, shows the rolling assemblies 4, 4'; 5, 5'; 6a, 6b and 6a', 6b' and their associated motors 7, all of which are similar to those described in connection with the first embodiment above, in the situation of travel on a gauge of the Spanish National Network type, with the transmission shafts 10, 10' extended.
  • the drive motors 7 are arranged in the central opening provided in the frame 2 by way of framework, in which said rolling assemblies are mounted slidably in the manner described above.
  • FIG. 4a shows, also, the mounting cantilevers 30 that, in the example illustrated, fix the stator 8 of the drive motor 7 to the frame 200 of the wheelset 100, for example by means of screws.
  • Fig. 4b shows a view similar to that in Fig. 4a, showing the rolling assembly in the situation adapted for travel on a European gauge, with the telescopic transmission shaft 10 totally withdrawn and housed completely inside the rotor 9 of the drive motor 7.
