Frame structure of process bogie and wheel base adjustment assemblies thereof

Abstract

The invention relates to a frame structure of a process bogie and wheel base adjustment assemblies thereof. The frame structure comprises a frame body and at least two wheel base adjustment assemblies. The at least two wheel base adjustment assemblies are arranged at intervals along the moving direction of traveling wheels, first adjusting parts are disposed on the frame body, and first connectingpieces are used for mounting the traveling wheels. In use, according to the model and size of a ground car lifting jack, the first connecting pieces are adjusted to be relative to the first adjustingparts to move in the moving direction of the traveling wheels. Since the traveling wheels are mounted on the first connecting pieces and the at least two wheel base adjustment assemblies are arrangedat intervals along the moving direction of traveling wheels, the wheel base of the at least two traveling wheels can be adjusted, the wheel base between the traveling wheels can adapt to the ground car lifting jack, and fixing of the vehicle body part of a subway vehicle to the frame structure is facilitated. Through the frame structure, the adaptability of the process bogie can be improved, andthe configuration of different types of process bogies can be avoided, and the maintenance cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance, in particular to a frame structure of a craft bogie and a wheelbase adjusting assembly thereof. Background technique [0002] In the process of maintenance of subway vehicles, it is often necessary to use the process bogie as the bearing equipment of the car body part of the subway vehicle to facilitate the maintenance of the subway vehicles. However, the wheelbase of the traditional process bogie is fixed, and one process bogie is only suitable for one type of ground crane. When multiple models need to be overhauled, multiple types of process bogies need to be used, resulting in high maintenance costs and poor adaptability of process bogies. Contents of the invention [0003] Based on this, it is necessary to provide a frame structure of a process bogie with an adjustable wheelbase and an wheelbase adjusting assembly thereof to address the above problems. [0004] A wheelbase adj...
