| Abstract: | The GKD2 diesel locomotive is equipped with 12 QB-4 unit brakes. In recent years, the failure rate of the unit brake on five locomotives has remained high. Therefore, the importance of correct judgment and timely disposal of unit brake failure is selfevident. This paper analyzes the causes of failure from the structure, working principle and environmental conditions of Qb-4 type unit brake, and puts forward relevant improving measures to further improve the service efficiency of QB-4 type unit brake. |
