Definitions

  • the present specification refers to a Patent of Invention - concerning a primary suspension for railway vehicles, the obvious purpose of which is to incorporate a primary suspension in an independent wheeled bogie in order to keep both a vertical position and a parallelism betwwen them during the vertical oscillations caused as a result of the running.
  • the inventor is not aware of the present existence of a primary suspension for railway vehicles disposing of the particular features represented by this invention.
  • the primary suspension for railway vehicles covered by the invention constitutes, itself, an evident novelty in this field.
  • the primary suspension for railway vehicles envisaged by this invention is shaped starting from a suspension incorporated to an independent wheeled bogie frame fixed in short axles, the bearing cases of which have, each of them, an arm stiffly united to that of its pair allowing the wheel assembly, short axle and bearing cases to oscillate in relation to the bogie frame, said arm being supported on flexible elements interposed between said bearing cases and the frame.
  • the purpose of the present invention is to allow to incorporate a primary suspension in an independent wheeled bogie, in order to keep both the vertical position and a parallelism between the same wheels, during the vertical oscillations caused as a result of the running.
  • each bearing case 3 and 4 has an arm 6, stiffly united to the arm of the other case 4 or 3, corresponding to the same wheel 5, through an axle 7 oscillating inside a horizontal arm 8, belonging to said frame, and it is supported on flexible elements 9 located between the bearing cases 3 and 4 and said axle 2 and the frame.
  • the purpose of the invention is to incorporate a primary suspension to an independent wheeled bogie, in order that these wheels keep both a vertical position and a parallelism between them during the vertical oscillations caused as a result of the running.
