Definitions

  • the invention relates to an undercar system for a railway vehicle as defined in the preamble of claim 1.
  • the invention has for its object to reduce the required number of pivots in an undercar system of the aforesaid kind whilst maintaining a satisfactory directional action of the axles.
  • the relative distances between a truck and next trucks may be unequal to one another, so that the axles can be arranged below the car bodies at the most favourable places in order to use the structure gauge as satisfactorily as possible.
  • the car bodies can be somewhat broader and shorter, so that a more efficient arrangement of seats in the car bodies can be realized.
  • the system described is suitable for a distribution of trucks below car bodies in a manner such that with adapted car body lengths a largest possible building width becomes possible within the limitations of the cinematic gauge.
  • the wheel sets need not be arranged below the car body ends and this has an advantageous effect of oscillation behaviour of the car body.
  • the rail vehicle 11 shown in Figs. 1 to 3 comprises three intercoupled car bodies 12 carried by an undercar system 9 embodying the invention, comprising a plurality-in this example eight-of uniaxled trucks numerated in order of succession from the left-hand end indicated in the drawing by 1, 2, 3, 4, 5, 6, and 8.
  • Each truck 1 to 8 comprises a frame 10 with two pivotal arms 14 journalled thereon and carrying each an axle bearing 15 holding a wheel set 16 formed by an axle 17 and two wheels 18 rigidly secured thereto.
  • the frame 10 is supported by means of spring packets 19 on the pivotal arms 14. Via air springs 20 and rubber springs 21 positioned in series therewith the frame 10 supports the car body 12 located above the same.
  • the trucks 1 to 8 are coupled with one another by means of steering means 24 for directing the wheel sets 16 towards a curve centre of the passed rail curve.
  • the steering means 24 comprise steering beams 27 which couple with one another the intermediate trucks 2, 3, 4, 5, 6 and 7 disposed each between two other trucks by means of their long middle portions 28.
  • each intermediate truck 3 to 6 comprises a spherical pivot 31 formed by a ball pivot, the ball 33 of which is embraced in a rubber layer 34, which allows some axial movement of the steering beam 27 relatively to the frame 10.
  • the spherical pivot 32 of Fig. 8 comprises a bridge piece 37 connected by means of rubber blocks 36 to longitudinal beams 35 of a frame 10 and extending transversely of a steering beam 27.
  • a pin 38 passes through ears 39 of the frame 10 and through a rubber block 36, so that the bridge piece 37 can slightly tilt about a horizontal axis 59 located at a higher level than the steering beam.
  • the bridge piece 37 has a lower piece 40 accommodating a ball pivot 41, which is not provided with rubber spring cushions and is engaged between two inner walls 42 of the steering beam 27 through a pivot pin 43. This ensures a rigid pivot in transverse direction between the steering beam 27 with respect to the frame 10 is enabled by the turn of the bridge piece 37 about the axis line 59.
  • Each car body 12 is coupled by means of a coupling rod 49 (Fig. 3) with a steering beam 27.
  • the steering beam 27 is entirely loose from each car body 12 carried by the coupled trucks 3 to 6 or in other words the trucks are mechanically interconnected while short-circuiting each car body 12. As a result movement of the car body 12 cannot disturb the action of the steering means 24.
  • the trucks 1 and 8 are identical to one another.
  • the trucks 2 and 7 are also identical to one another, so that hereinafter only the trucks 1 and 2 will be described.
  • the frame 10 of truck 1 is provided with an arm 44, which is coupled by means of a spherical pivot 30 with the short end portions 29 of the steering beam 27, which is pivotally connected with the frame 10 of truck 2 by means of a spherical pivot 31.
  • the trucks 1 and 2 are disposed near one another and movably connected with one another by means of the coupling mechanism 45 consisting of a bridge piece 47 corresponding to the bridge piece 37 and extending transversely of the direction of movement 46, said bridge piece 47 being pivotally connected both to the first and the second truck 1 and 2 by means of spherical pivots 48.
  • the arm 44 constitutes a prolongation of the frame 10 extending beyond the coupling mechanism 45 of the truck 1.
  • the wheel sets 16 of the trucks 1 to 8 have pitch distances a, to a 7 (see fig. 1).
  • the places of the pivots 30, 31 and 32 in the intermediate trucks 3,4,5 and 6 are determined as follows.
  • the pivots 31 and 32 are disposed on both sides of the wheel axle 16 at a relative distance 2v.
  • the wheel set 16 has an eccentrical shift e with respectto the middle of the distance 2v. In figs. 1 to 8 e is equal to v.
  • the eccentricity e for the intermediate trucks 3 and 5 is directed to the right and for the intermediate trucks 4 and 6 to the left as shown in the situation of fig. 9 the following formulae apply to the short arm p and q:
  • the distances a3 and a 5 bridging the bellows couplings 50 between the car bodies 12, are smallerthan the distances a 2 , a4 and as.
  • the traction motors 51 are arranged at the distances a3 and a 5 . They are suspended to the steering beams 27.
  • These axles 17 (see fig. 10) are driven by these traction motors 51 through hollow gear boxes 52 surrounding the axles 17 and through a coupling 53.
  • a brake 54 is provided on the axle 17. The space over the distances a 2 , a4, as thus remains free for arranging other apparatuses.
  • the undercar system is suitable, not only for suspending thereto electric traction motors, but also for suspending thereto combustion engines having electric, hydraulic, hydrodynamic or mechanical transmissions and for suspending apparatus boxes and ducts.
  • the arrangement of the wheel sets 16 below the car bodies 12 is furthermore such that the free space profile is most satisfactorily utilised and the seat distribution is most efficient. On the side of the passage path each time five seats 56 or four ample seats 57 can be arranged. Thus the useful floor surface per wheel axle 16 is larger.
  • the undercar system embodying the invention can also be used with wheel sets having independently rotatably journalled wheels.
