202型转向架自1958年设计並于1959年试制完成后,到目前为止已在近千辆车上装用。这种转向架主要是为适应铁路旅客列车速度不断提高的要求而进行设计的,因此,在结构上采用的新技术比较多,並第一次在我国鉄路客车转向架上采用了油压減振器。经过几年来的制造和运用证明,这种转向架的制造和检修成本低,在正常运用情况下振动 202 bogies have been designed and built in 1958 and completed in 1959, so far they have been installed on nearly a thousand vehicles. This kind of bogie is mainly designed to meet the requirements of the increasing speed of railway passenger trains. Therefore, the new technology adopted in the structure is relatively large, and for the first time, hydraulic damping is adopted on the bogie of Kushiro bus in our country Device. After several years of manufacturing and operation proved that the bogie manufacturing and maintenance costs low, under normal conditions of vibration
