Abstract
A side frame for a bogie. Two longitudinal sides of the side frame are respectively provided with a supporting seat for connecting an end portion of a connecting rod, and the supporting seat is integrally formed with the side frame by casting. The supporting seat includes a supporting plate, a middle rib and a first side rib. The supporting plate is provided with a through hole. The connecting rod and the supporting seat are thread-connected via a conical pole which is fixedly provided in the through hole. The side frame reduces the welding processes, ensures the installation precision of the supporting seat, and enhances the strength of the supporting seat.
