Abstract

The present invention provides a sideframe for use in a traditional three piece railway fright car truck comprising a pair of laterally spaced sideframes supporting a bolster extending between the sideframes. Each sideframe comprises an elongated top compression member, two diagonal compression members extending generally downwardly at acute angles from near the ends of the top compression member, and a bottom member joining the other ends of the diagonal tension members. Two column members also extend vertically between the bottom member and the top compression member. Pads with fastener openings are provided on the top surface of the top compression member to assist in mounting brackets to the sideframe.

Claims (86)

1. A sideframe for use in a railway car truck,

said sideframe of a generally unitary cast steel structure comprising an elongated top compression member extending longitudinally,

two end sections each extending longitudinally from an end of said top compression member and each forming a pedestal jaw,

two diagonal tension members each extending at an acute angle with said top compression member from near said end of said top compression member,

a bottom member extending longitudinally and joining said diagonal tension members at a lower end of each diagonal tension member,

two column members longitudinally spaced from each other extending vertically between said bottom member and said top compression member,

said column member forming a bolster opening between,

the top compression member including two elongated longitudinally spaced generally flat pad sections, each of which extending laterally across a majority of the lateral width of the top compression member, each of the pad sections having fastener openings extending through the pad section and the top compression member,

further including two side sections each extending between the top compression member and the diagonal tension members,

and a side fastener opening extending through each side section below the top compression member.

2. The sideframe of claim 1 ,

wherein each side section includes two side fastener openings,

the side fastener openings in each side section being spaced longitudinally from each other.

3. The sideframe of claim 1 ,

wherein each side section includes two side fastener openings in each side section being located above the diagonal tension member.

4. The sideframe of claim 1 ,

wherein the side fastener openings extending through the side sections are aligned.

5. The sideframe of claim 1 ,

wherein the pad sections are located above the bolster opening.

6. A sideframe for use in a railway car truck,

said sideframe of a generally unitary cast steel structure comprising an elongated top compression member extending longitudinally,

two end sections each extending longitudinally from an end of said top compression member and each forming a pedestal jaw,

two diagonal tension members each extending at an acute angle with said top compression member form near said end of said top compression member,

a bottom member extending longitudinally and joining said diagonal tension members at a lower end of each diagonal tension member,

two column members longitudinally spaced from each other extending vertically between said bottom member and said top compression member,

said column member forming a bolster opening between,

the top compression member including longitudinally spaced, generally flat pad sections,

each of the pad sections having a fastener opening extending through the pad section and the top compression member,

further including two side sections each extending between the top compression member and the diagonal tension members, and

a side fastener opening extending through each side section below the top compression member.

7. The sideframe of claim 6 ,

wherein each pad section is raised above a top surface of the top compression member.

8. The sideframe of claim 6 ,

wherein the longitudinally spaced pad sections are provided in laterally spaced pairs.

9. The sideframe of claim 6 ,

wherein each of the pad sections extends laterally across a majority of the lateral width of the top compression member.

generally flat pad sections each of which extending across a majority of the lateral width of the top compression member,

each of the pad sections having two laterally spaced fastener openings extending through the pad section and the top compression member,

and two side sections each extending between the top compression member and the diagonal tension members,

and a side fastener opening extending through each side section below the top compression member.

14. The sideframe of claim 13 ,

wherein each side section includes two side fastener openings,

the fastener openings in each side section being spaced longitudinally from each other.

15. The sideframe of claim 13 ,

wherein each side section includes two side fastener openings,

the side fastener openings in each side section being located above the diagonal tension member.

16. The sideframe of claim 13 ,

wherein the side fastener openings extending through the side sections are aligned.

17. The sideframe of claim 13 ,

wherein the pad sections are located above the bolster opening.

18. A sideframe for use in a railway car truck,

said sideframe of a generally unitary cast steel structure comprising an elongated top compression member extending longitudinally,

two end sections each extending longitudinally from an end of said top compression member and each forming a pedestal jaw,

two diagonal tension members each extending at an acute angle with said top compression member form near said end of said top compression member,
