ABSTRACT:
A railroad-vehicle truck with a frame that yields under torsion and consists of transoms (2) and side frames bars (1) welded into an H. The transoms (2) are positioned such that the planes that the transom webs (2k) lie in intersect at one line (S7), which lies between the flanges (21) of the transoms. Each of the flanges of the transoms are fastened to one of the upper and lower flanges on the depressed middle section of the side frame. Helical compression springs are positioned on the upper flanges of the depressed section, with a bolster on the springs, and load dependent side bearings between the compression springs and the bolster. The side frames are resistant to torque over their total length, but the transoms yield under torque. Thus the truck has sufficient corner rigidity and prevents high material stresses caused by torque.
