Description

Technical Field

[0001] This utility model belongs to the field of subway maintenance technology, specifically relating to a process bogie for subway maintenance. Background Technology

[0002] During subway maintenance, process bogies are typically used to replace the original bogies, providing support, displacement, and positioning for the car body to complete various maintenance tasks. Currently, most process bogies used in subway maintenance serve only a specific car model and are generally welded frame type process bogies, including wheelset assembly, frame assembly, bolster assembly, and support assembly. The support assembly has locating pins to ensure good positioning and support with the car body. However, the existing shortcomings are that the spacing of the support assembly is not adjustable, which cannot meet the needs of different cars at the same time; when mating with the car center pin, it is not considered how the center pin sleeve can still have a good fit with the center pin if the fit between the center pin sleeve and the center pin is too tight or too loose, or if the installation dimensions do not match; and there is no interface for connecting with the car body anti-roll torsion bar.
