ABSTRACT:
The present invention provides a railway truck sideframe with a strengthened bottom member. The sideframe comprises an elongated top compression member, two diagonal tension members extending 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. The top surface of the bottom member is usually referred to as a spring seat as such top surface provides support for the spring group on which the railway truck bolster is supported. The bottom member and attached diagonal tension members are strengthened by the addition of internal support ribs within the generally hollow bottom member near the intersection with the diagonal tension member. An increased thickness in the intersection of the top surface of the bottom member and the diagonal tension member and/or column is also provided.
