The method to increase the wedge wedging quality and measure whether the bolster and the side frame are in the right position after the completion of the turning wedge is put forward. It is also demonstrated that to ensure the positive position of the bogie and improve its running quality is to reduce the end grinding of the bearing bush and reduce An effective way of thermal axis rate. At the same time, on the wedge planing special fixture and a new wedge wedge structure, the use of a more detailed description.
