Definitions

  • the present invention relates to bogies for cars, primarily for railway cars. More particularly the invention relates to bogies including a frame having spaced wheel and axle assemblies. In accordance with the invention, the frame is provided with a recess disposed between the wheel and axle assemblies and receiving a bolster which is resiliently supported in the frame by means of springs. The car body rests on the bolsters of two such bogies so as to permit pivotal movement about a vertical axis between the respective bogies and the car body.
  • a further object is to provide a bogie which is capable of effectively damping the oscillations of the car body.
  • Still another object is to provide a bogie, the bolster of which is adapted to absorb shocks and sound to a high degree so as to prevent the same from being transmitted to the car body.
  • Fig. 1 shows a lateral view of a bogie embodying the invention.
  • Fig. 2 is a top view of the bogie.
  • Fig. 3 is a sectional view taken on the line IIIIII of Fig. 2.
  • Fig. 4 shows a portion of the bogie in the same sectional view as Fig. 3 but on an enlarged scale
  • Fig. 5 is a sectional view taken on the line VV of Fig. 2 and on an enlarged scale.
  • reference character generally denotes the frame of the bogie and 12 two axially spaced axles which are journalled in bearings 14 and carry two pairs of wheels 16 adapted to run on tracks.
  • the frame includes central transversely extending members 18 which together with the longitudinally extending members 20 of the frame form an opening 22 (Fig. 2 of rectangular shape and which may be connected to the lateral cross members 24 of the frame 10 by reinforcing members 26 in a known manner.
  • a bolster 28 Disposed in the opening 22 is a bolster 28 comprising a top plate 30, lateral plates 32 and cross plates 34 secured to the plates 30 and 32.
  • a pad 36 having a concave upper surface 38 and a central bore 40 is secured to the top plate 30 and is adapted to support a corresponding pivot member on the car body to allow relative pivotal movement between the latter and the bogie in a horizontal plane.
  • a plurality of cantilever springs 42 extend transversely through the opening 22 and are mounted in the longitudinal frame members 20.
  • the two cross plates 34 which are spaced at equal distances from the middle of the bolster, as is best shown in Fig. 3, are provided with bearing journals 44 in the form of short tubes closed at their ends as at 45 and having openings 46 through which the springs 42 pass.
  • Segments 48 of a bearing material such as a composite of plastic or metal, are located in the interior of the journals 44 on both sides of the springs, said segments turning in the journals 44 when the springs are bent.
  • supports 52 are provided on which rest resilient cushion members 54, such as of rubber or like material, disposed between and secured to plates 56 and 58 by an adhesive in known manner.
  • the upper plate 58 has a recess 60, which is engaged by the end of the spring 42, the latter being bent downwardly, as at 62, so as to determine the lateral relative position between the spring and the cushion member 54.
  • the springs may be of the laminated leaf type generally used in cars, but as such springs, on account of friction between the leaves, have a variable spring characteristic, single blade springs are preferred, which for obtaining easy spring action and smooth riding of the car body preferably have a rectangular, or I, or like cross section, the height of which decreases towards the ends of the springs. In the embodiment illustrated this form is obtained by progressively reducing the height of the central web 50 of the spring.
  • resilient members 68 such as of rubber, adapted to bear against vertical plates on the longitudinal frame members 20 so as yieldingly to support the bolster in horizontal direction laterally of the bogie and, if mounted with an initial pressure, also to damp the rocking and canting of the bolster and the car body thereon.
  • members 64 of the same character are provided between the longitudinal lateral faces of the bolster 28. Said members are adapted to bear against vertical plates 66 and to support the bolster in horizontal direction, that is, the longitudinal direction of the bogie. By giving the cushion members an initial pressure the friction between the cushions and the plates 66 contributes to damp oscillation of the bolster and the car body thereon.
  • the springs 42 carrying at least substantially the weight of the bolster and the car body thereon, ensure for the car, particularly if they are of the described single blade type, a smooth vertical riding action.
  • the rubber members 54 and 68 additionally act to allow a resilient movement of the bolster and springs laterally of the bogie as well as to prevent noise and vibrations from being transmitted through the bolster to the car body.
  • the cushion members 68, and additionally the members 64 if they are under initial pressure, provide friction against the bearing plates 70, 66, respectively, whereby the oscillations from the wheel and axle assemblies and the bogie frame are clamped to a considerable extent, as the car rolls over the inequalities of the track.
  • the members 68 effectively absorb shocks which may occur, such as when the car passes curves or the like and the bolster is moved laterally of the bogie by the centrifugal force acting on the car body.
  • the initial pressure between the member 68 and the plate 70 is increased, as is also the friction between the same, whereby the canting of the car body is reduced.
  • the internal friction of the material of said members acts to damp such small oscillations.
  • a bogie the combination with a frame having spaced longitudinal members and spaced transverse mem- 7 free to r 3 bers, of a bolster and means for supporting the bolster in the frame comprising at least one transverse spring, resilient yieldable supports on said longitudinal members operatively engaged by the ends of said spring to support the. same, and two intermediatexsupports carried by said bolster and engaged by said spring intermediate the ends thereof to support the bolster, said intermediate supports being spaced approximately equidistantly from the longitudinal-center line of the frame and the portion of the spring between the spaced intermediate supports being flex in a direction substantially perpendicular to the longitudinal center line of the spring.
  • a structure as set forth in claim 1 including pads of resilient non-metallic material located between the longitudinal members of the frame and adjacent portions of the bolster, said pads being initially compressed when the parts are assembled.
