Problems solved by technology
[0004] Shortcomings of the prior art: (1) the current brake shoe pin ring 40' is made of low-carbon steel wire, and the strength of the low-carbon steel wire is low, and the brake shoe pin ring 40' is easily deformed under the action of external force
[0005] (2) After the brake shoe pin ring 40' is installed, the overlapping amount of the steel wire is 10mm (or the arc angle of the overlapping area is 30°), the overlapping amount is relatively small, and the brake shoe pin ring 40' is deformed under the action of external force After that, the overlapping part is easy to open, so that the brake shoe pin ring 40' is easy to come off from the brake shoe pin 30'
[0006] (3) Now the brake shoe pin ring 40' is difficult to disassemble and assemble by hand because the steel wires in the overlapping area are tightly attached

Embodiment Construction
[0026] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0027] Such as figure 2 with image 3 As shown, the first embodiment of the present invention provides a brake shoe pin ring, which includes a pin ring body 41 and a detachable part 42 . The pin ring body 41 is configured as a ring structure, and overlapping portions of the ring structures form overlapping areas of the pin ring body 41 . The detachable portion 42 extends from at least one end of the pin ring body 41 in a direction away from the pin ring body 41 and protrudes to the outside of the pin ring body 41 .
[0028] The dismounting part 42 is provided, and the staff can manually open the overlapping area through the dismounting part 42, and install the brake shoe pin ring on the mat...

The invention provides a brake shoe pin ring, a bogie and a railway wagon. The brake shoe pin ring comprises a pin ring body which has an annular structure of which the overlapping portion forms the overlapping region of the pin ring body, and a disassembly and assembly portion which extends from at least one end of the pin ring body away from the pin ring body out of the outer side of the pin ring body. By arranging the disassembly and assembly portion in the brake shoe pin ring, working personnel can open the overlapping region manually through the disassembly and assembly portion, and arranges the brake shoe pin ring on a matched workpiece, thereby fulfilling the aim of bringing convenience to manual disassembly and assembly of the brake shoe pin ring.
Description
technical field [0001] The invention relates to the field of rail transportation tools, in particular to a brake shoe pin ring, a bogie and a railway freight car. Background technique [0002] Such as figure 1 As shown, in the prior art railway freight car bogie braking device, the brake shoe 10' is installed on the arc surface of the brake shoe holder 20', and is inserted into the middle of the brake shoe holder 20' through the shoe nose of the brake shoe 10' In the groove, the brake shoe pin 30' is inserted from top to bottom, passing through the matching hole of the brake shoe holder 20' and the shoe nostril of the brake shoe 10', so that the brake shoe 10' is fixed on the brake shoe holder 20'. Simultaneously, in the process of using or turning over the bogie process, in order to prevent the brake shoe pin 30' from coming out of the brake shoe holder, a brake shoe pin ring 40' is installed in the round hole at the bottom of the brake shoe pin 30'. [0003] The structur...
