Definitions

  • This invention relates to railway vehicles and more particularly to improvements in cast steel truck bolsters for such vehicles.
  • an object of this invention is to provide an improved cast bolster design with considerably improved strength qualities that is capable of withstanding severe dynamic service loading notwithstanding the presence of large brake rod openings therein.
  • FIGURE 1 is a top fragmentary view, partly in section, of a truck bolster that incorporates the features of the presently described invention
  • FIGURE 2 is a side sectional view, taken substantially along section line 2-2 of FIGURE 1;
  • FIGURE 3 is a sectional view taken along section line 3-3 of FIGURE 2;
  • FIGURE 4 is a sectional view taken along section line 4-4 of FIGURE 2;
  • FIGURES 5, 6 and 7 are sectional views showing several modifications of the present invention, said views being taken along a line corresponding to section line 5-5 of FIGURE 2.
  • the bolster comprises a substantially horizontal top wall or compression element 10 and a bottom wall or tension element 12 that extends longitudinally upwardly from a central horizontal portion thereof.
  • Elongated outer vertical side walls 14 extend between top and bottom walls 10 and 12, respectively, along the length thereof to form an elongated box structure of greater vertical depth in the central portion of the bolster.
  • a center plate 16 is centrally located on the top wall 10, and a central aperture 18 is provided through the bolster for reception of a king pin (not shown).
  • central aligned apertures 20 may be provided in each side Wall 12 for reception of a king pin retainer (not shown).
  • Brake rod openings 22 are provided through the side walls 14 on both sides proximate the central vertical axis thereof, and secondary openings 23 and 25 are provided on both sides distal from said axis, it being understood that the bolster is substantially symmetrical about its transverse vertical center plane AA and longitudinal vertical center plane BB (FIG. 1).
  • a pair of central vertical supports 24 are provided that extend between the top and bottom walls 10 and 12, respectively.
  • Vertical supports 24 are located between and interconnect a pair of spaced internal vertical walls 26 that extend for the entire length of the bolster substantially parallel to the longitudinal center plane BB thereof.
  • Transverse vertical webs 28 are provided between a central potrion of each side wall 14 and its adjacent internal vertical wall 26 along the transverse center plane AA of the bolster.
  • one or more box sections are provided in the internal structure of the bolster and extend longitudinally in said bolster from the transverse vertical center plane thereof, preferably beyond the diameter of the center plate.
  • the box sections 30 are transversely spaced and adjoin the top or bottom and an adjacent side wall of the bolster and are formed by the addition of a transverse web 32 between an external side wall 14 and its adjacent internal vertical wall 26, said web being spcaed from each of the top and bottom Walls 10 and 12, respectively.
  • box sections 30 at both the top and bottom of the bolster, as shown.
  • the transverse webs 32 forming the box sections 30 extend approximately between central vertical supports 24 and are curved to conform to the shape of the brake rod opening 22.
  • the webs 32 curve inwardly around the openings 22 from a substantially horizontal central section thereof.
  • an additional transverse web 34 may interconnect the two internal vertical walls 26, resulting in an additional, central box section, generally indicated at 36, interconnecting the otherwise transversely spaced box sections 30.
  • FIGURE 6 Another embodiment is shown in FIGURE 6.
  • a single box section, indicated generally at 38, is formed by the provision of a single transverse web 40 between the internal vertical walls 26, with the other transverse webs 32 being omitted.
  • FIGURE 7 Still another embodiment is shown in FIGURE 7, wherein the aforementioned "box sections 30 are provided in the top of the bolster only, with the transverse webs 32 being omitted at the bottom. It should now be obvious that any combination of the above box sections, including one, two or three box sections at the top or bottom only, as well as one, two or three box sections at the top and bottom or any combination thereof would be feasible in the practice of the presently described invention.
  • a railway truck bolster including a top wall having a centrally disposed center plate, a bottom wall, and a pair of spaced side walls connected between said top and bottom walls, the improvement comprising a pair of spaced internal vertical walls connected between said top and bottom walls, and a horizontal web connected between said internal vertical walls and spaced from said top and bottom walls along its entire length, said horizontal web extending longitudinally within said bolster at least substantially the breadth of said center plate.
  • a second horizontal web is connected between said internal vertical walls and is spaced from said top and bottom walls and said first horizontal web, said second horizontal web extending longitudinally within said bolster at least substantially beneath said center plate.
  • a railway truck bolster including a top wall having a centrally disposed center plate, a bottom wall, and a pair of spaced side walls connected between said to and bottom walls, the improvement comprising a pair of spaced internal vertical walls connected between said top and bottom walls and spaced from said side walls, a pair of substantially vertical support members extending between said top and bottom walls and between said internal vertical walls, said vertical support members being spaced longitudinally in said bolster from the transverse vertical center plane thereof, and at least one horizontal web con nected between said internal vertical walls and extending between said vertical support members, said horizontal web being entirely spaced along its entire length from said top and bottom walls.
  • a railway truck bolster including a to wall having a centrally disposed center plate, a bottom wall, and a pair of spaced side walls connected between said top and bottom walls, the improvement in said structure comprising a pair of internal vertical walls spaced from said side walls and connected between said top and bottom walls, and a horizontal web connected between each of said internal vertical walls and its respective adjacent side wall, said horizontal webs extending longitudinally within said bolster at least substantially beneath the length of said center plate.
  • openings are provided in the side walls of said bolster, and wherein said horizontal webs curve around a portion of said openings.
  • a railway truck bolster including a bottom wall, a top wall having a centrally disposed center plate, and a pair of spaced side walls interconnecting said top and bottom walls, the improvement comprising a pair of internal vertical walls spaced from said side walls, a pair of vertical support members connected between said internal vertical walls and spaced longitudinally in said bolster from the transverse vertical center plane thereof, a vertical web connected between at least a portion of each internal vertical wall and its respective adjacent side wall, and at least one horizontal web connected between each side wall and its adjacent internal vertical wall, said horizontal web extending longitudinally in said bolster substantially beneath said center plate.
