Abstract

A primary suspension for railway vehicles consisting of providing a bearing box (3) with an arm (6) that, stiffly united to the arm (6) of the other bearing box (4) corresponding to the same wheel through an axle (2), oscillates inside a horizontal arm (8) belonging to the frame, and which is supported on flexible elements (9) intermediate between the bearing boxes (3,4) of said axle (2) and the frame, disposing of a stiff union between the bearing boxes (3,4) of each wheel by means of the axle (2) allowing the assembly to oscillate in relation to the bogie frame about a horizontal axle (7).

Description

    BACKGROUND OF THE INVENTION
  • 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.
    • FIELD OF THE INVENTION
  • The application of this invention is envisaged to the railway industry.
    • RELATED ART
  • 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.
  • Obviously, he is aware of several suspensions used on railway vehicles, which are greatly different from the one covered by this invention.
    • SUMMARY OF THE INVENTION
  • The primary suspension for railway vehicles covered by the invention constitutes, itself, an evident novelty in this field.
  • In a more definite way, 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.
  • It is evident that 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.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • In order to supplement the present description and to help to a better undestanding of the features of the invention, the appending drawings, which are a part of this specification, show in an illustrative but not limitative way, the following:
    • Figure 1 shows a front elevational view of the primary suspension for railway vehicles covered by the invention.
    • Figure 2 is a side elevational view of the object shown in Fig. 1.
    • Figure 3 shows, lastly, a plan view of the object representated in the above figures.
    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • From these Figures, it can be clearly seen the primary suspension for railway vehicles, which is the object of the present invention, intended to be incorporated between an independent wheeled bogie frame 1 and a short axle 2, which is mounted between two bearing cases 3 and 4, per each wheel.
  • The primary suspension for railway vehicles has an own significance in that 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.
  • In synthesis, it can be said that 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.
  • It is not considered necessary to extend more this description for an expert in the art to understand the scope of the invention and the advantages derived from it.
  • The materials, shape, size and arrangement of its components are open to variation, provided that it does not imply any alteration to the essence of the invention.
  • The terms under which this specification has been described should be taken in an ample and non limitative sense.

Claims (3)

  1. A primary suspension for railway vehicles, of the type intended to be incorporated between an independent wheeled bogie frame (1) and a short axle (2), mounted between two bearing cases (3) and (4) per wheel (5), characterized in that each bearing case has an arm (6) that, stiffly united to the arm of the other case corresponding to a same wheel,through an axle (7), oscillated inside a horizontal arm (8), belonging to said frame and supported on flexible elements (9) intermediate between the bearing cases of said axle and the frame.
  2. A primary suspension for railway vehicles, according to claim 1, characterized in that it has a rigid union between the bearing bases (3) and (4) of each wheel by means an axle (7) which allows the assembly to oscillate in relation to a bogie frame (8) according to a horizontal axle.
  3. A primary suspension for railway vehicles, according to any of the preceding claims, characterized in that it has two bearing cases (3) and (4), which are leant on the bogie frame through flexible elements (9).
