Description

Technical Field

[0001] The utility model relates to the technical field of railway freight car bogies, in particular to a railway frame type bogie and a railway freight car. Background Art

[0002] At present, welded frame bogies basically use guide frame axle box for positioning. During the operation of the bogie, the axle box and the guide frame rub against each other, causing the guide frame to be worn, shortening the service life of the guide frame and increasing the maintenance cost of the bogie.

[0003] Therefore, in order to protect the guide frame from wear, a wear plate is usually installed on the guide frame. When the wear plate is worn to a certain thickness, it needs to be replaced. However, since the wear plate is usually welded to the guide frame, it is necessary to remove the original wear plate and weld the new wear plate on. This process requires special tools such as welding machines and angle grinders. At the same time, the guide frame is often damaged during the disassembly process, resulting in high maintenance costs and long maintenance cycles. Utility Model Content

There is no need to prepare special tools such as welding machines and angle grinders, which avoids problems that may occur due to improper welding operations and increases the safety of the installation of the wear plate 2. At the same time, the guide frame 1 will not be damaged during the disassembly process of the wear plate 2, thereby improving the replacement efficiency of the wear plate 2.
