Definitions

  • the present invention relates to a steering bogie for railway cars.
  • Steering railway car bogies which are equipped with complex lever systems, which lever systems are generally fastened either to the axle boxes or to the axles, and result to be cumbersome inside the interior or the bogie.
  • this type of steering bogies require a lot of servicing and in the overall are subject to high wear rates, which jeopardize very soon the efficiency of the system.
  • the purpose of the present invention is of obviating the drawbacks which affect said prior art.
  • a steering bogie for railway cars which is constituted by a chassis defining a longitudinal axis thereof, and equipped with at least two axle-wheels units defining a longitudinal axis of their own, each one of said axle-­wheels units being provided with two axle boxes, each one of said axle-wheels units being connected with said chassis of said bogie by means of primary suspensions positioned laterally to said axle boxes, said longitudinal axis of said railway car bogie being in an orthogonal position relatively to said longitudinal axes of said axle-wheels units under resting operating conditions or when the railway car runs along a straight track portion, characterized in that between said chassis of the bogie and each axle box of said axle-wheels units a jack is interposed, which is capable of generating a plurality of forces concurring to position said longitudinal axes of said axle-wheels units in an angular position different from said orthogonal position.
  • a bogie according to the present invention is generally indicated by the reference numeral 10.
  • Such a bogie 10 is essentially constituted by a chassis 11 onto which two axle-wheels units 12 are fastened by means of axle boxes 13 connected with primary suspensions 14.
  • the primary suspensions 14 are connected with the chassis 11 of the bogie.
  • a jack 15 is provided, which is fastened to the chassis 11 at a higher level than the level at which the axle box 13 is fastened.
  • the jacks 15 are furthermore connected with a control system, which is schematically indicated by the reference numeral 16 in Figures 2 and 3.
  • the primary suspensions of this type of bogies preferably are large-rubber-volume suspensions, or rolling-rubber-ring suspensions, or steel spring suspensions, with helical springs of cylindrical or conical shape.
  • the bogie 10 will be in the schematic configuration shown in Figure 2.
  • Figure 3 shows the configuration assumed by the bogie 10 while traveling along a track bend.
  • the jacks 15 of the internal side of the bend are retracted, and the jacks of the external side of the bend are in their extended position.
  • the axle boxes 13 compress the elastic element of the suspensions which, as said, can be rubber, or can be a steel spring, thus enabling the axle-­wheels units 12 to modify the position of their axis 21 relatively to the axis 20 of the bogie.
  • axles 21, from their position perpendicular to the axis 20 will therefore come to coincide with the radius of curvature of the bend along which the bogie runs.
  • Another advantage of the present invention is that the jacks 15, by being in an oblique position, generate a vertical force component directed downwards, which considerably contributes to increase the stability of the railway car when traveling along bends, by favouring the adherence of the bogie to the track. Furthermore, it is forecast that a type of bogie like the one herein diclosed can be used both for railway cars or vehicles of the variable-trim type, and of conventional type.
