Definitions
- This invention relates to a railway bogie comprising a bolster secured between two hollow section side [30] Foreign Application Priority Data frames, in which the bolster ends are flanged and each June 22, 1973 United Kingdom 29794/73 is Welded around its edge the surface of a mating aperture or recess in the inner side of the side frame. 52 C
- the recess may be 5 Field f Search n 105 /1 82 R 200, 206 A constituted by either an integrally formed shoulder 105 /202, 226 ring or a separate backing ring secured around the aperture.
- 5 References Cited this ring may be removed so as to expose the inner UNITED STATES PATENTS weld seal, a weld bead then being laid from the inside.
- This invention relates to railway bogies, and in particular concerns the manner in which the bolster is secured to the side frames.
- Bogies are usually fabricated from multi-part structures, i.e. the bolster is secured between two side frames. With this manner of fabrication the bolster ends are normally welded to the side frames and it is usual for the ends to be machined to fit into apertures which accommodate them.
- One particular form of construction of this I-I-frame type includes the use of hollow-section side frames which have co-axial apertures in their inner and outer walls, the bolster ends extending through these apertures and having annular machined areas which align with the side frame walls and are fillet welded to them.
- the present invention provides a method of securing a bolster between two hollowsection side frames in the construction of a railway bogie, in which the bolster ends are flanged and each is welded around its peripheral edge'to the surfaces of a mating aperture or recess in the inner wall only of the respective side frame.
- the invention also provides a railway bogie comprising a bolster secured between two hollow-sectionside frames, in which the bolster ends are flanged, each of which has been welded around its peripheral edge to the surface of a mating aperture or recess in the inner side only of the respective side frame.
- the peripheral edge of the flanged end may lie wholly within the inner wall of the side frame and it may be circular; the bolster section may be strengthened, at least in the area of the flange, by stiffening ribs.
- An aperture may also be provided in the outer wall of each side frame in alignment with the inner aperture or recess.
- the recess may be constituted by either an integrally formed shoulder ring or a separate backing ring secured within the side frame around the aperture. Depending on the weld classification required, this ring may be removed so as to expose the inner weld seal, a weld bead then being laid from the inside.
- the whole assembly may be made from cast steel.
- the weight of the bogie is also reduced as compared with the through end design.
- FIG. 1 is a plan view of the bogie structure
- FIG. 2 is a sectional side elevation through A A in FIG. 1',
- FIG. 3 is a detail of part of the weld junction shown in FIG. 2;
- FIG. 4 is an axial section through B B in FIG. 2.
- the bogie comprises a H-frame structure including a bolster 1 secured between two side frames 2.
- Two side bearers 3 are mounted on the bolster and lie on opposite sides of a .centre pivot 4 to which the carriage is secured.
- Two wheel and axle assemblies 5 are mounted in journal housings (not shown) adjacent the ends of the two side frames.
- the side frame 2 is of hollowed rectangular section and has circular apertures 7, 8 formed in its side walls.
- the aperture in the outer wall is provided to lighten the bogie and provide access as described below, whilst the inner aperture 8 is in the form of a machined recess providing, with an integrally cast backing ring or shoulder 9, location for the flanged end 10 of the bolster.
- the bolster which is of hollow circular section (at least adjacent its ends) has a number of integral stiffening ribs 11- to add strength, particularly in the area of the flange.
- the end surface 12 of the flanged end is machined so as to abut the shoulder, these two abutting surfaces governing the width'of the finished assembly and the peripheral edge 13 of this end is machined in like manner to the side frame providing a Vee-trough 14 for the weld (see FIG. 3).
- This trough preferably includes an angle of not less than 60 and a penetration land 15 is machined to enable the welding rod used to bottom on the ring.
- the machined preparation for the weld provides both lateral positioning and longitudinal positioning, ensuring parallelism between the side frames.
- the assembly is clamped together and the annular through weld (16) to the shoulder is laid down. This may be effected by moving the welding head around the trough or by rotating the whole assembly about the bolster arm axis relative to a stationary welding head.
- the shoulder may be machined off, e.g. by hand grinding, access being obtained through the aperture 7 and a bead weld may be laid on the inner side of the exposed through weld if desired.
- a separate pre-machined ring may be secured in place to provide location. This may be removed afterwards as before.
- a railway bogie comprising two hollow-section side frames each defining an aperture in one side and spaced apart with the apertured sides facing one another;
- a bolster terminating in flanges extending transversely of the longitudinal axis of the bolster, said bolster being secured between the said sides of the side frames by the flanges having been welded around their peripheral edge to the mating surface of the associated aperture in the side frames.
- a bogie according to claim 2 wherein the periphery of each flanged end of the bolster is circular.
- side frames each define, in alignment with the said aperture in their one side, an aperture in their other side.
- a bogie according to claim 2 comprising a shoulder ring extending around the aperture within each side frame, by which a recess is constituted.
- a method of securing a bolster between two hollow-section side frames in the construction of a railway bogie said bolster having ends terminating in flanges extending transversely of the longitudinal axis of the bolster, in which the flanged ends of the bolster are each welded around their peripheral edges to the surfaces of the boundary walls of a mating aperture in the inner wall only of the respective side frame.
- each aperture is constituted by a shoulder ring extending around the aperture within the side frame, in which after the welds have been completed, the ring is removed so as to expose the weld seal, a weld bead then being laid on this sea] from the inside.
- a railway bogie comprising; two hollow-section side frames each defining an aperture in one side and spaced apart with the apertured sides facing one another; a bolster having flanged ends, the peripheral edge of each flanged end lying wholly within the associated aperture of the respective side frame, said bolster being secured between the said sides of the side frames by the flanges having been welded around their peripheral edge to the mating surface of the associated aperture in the side frames.
