Abstract
A three piece rail car truck has a pair of side frames, a pair of wheelsets and a roller bearing adapter seated on each end of each wheelset. Each side frame has pedestal jaws formed and adapted to seat upon each roller bearing adapter. The improvement comprises a stabilizer bar connected between each roller bearing adapter and an adjacent portion of a side frame, with the stabilizer bars resisting unsquaring relative movement between the wheelsets and side frames.
Claims6
A three-piece rail car truck having a pair of side frames, a bolster extending between said side frames, a pair of wheelsets, roller bearing adapters, each of which is seated on an end of said wheelsets, each of said side frames having a pedestal at each end thereof formed and adapted to seat upon one of the roller bearing adapters, the improvement comprising a stabilizer bar connected between each of said roller bearing adapters and an adjacent portion of one of said side frames, the connection between each of said stabilizer bars and one of the roller bearing adapters being rigid, the connection between each of said stabilizer bars and one of the side frames providing for limited movement therebetween, each of said stabilizer bars being significantly less stiff than an axle or the side frames and functioning as a yaw spring stiffness between said axle and side frame, thereby resisting unsquaring relative movement between the wheelsets and side frames.
