Abstract

The invention discloses a brake assembly, which comprises a brake disc arranged under a vehicle frame and a guide rail located between the vehicle frame and the brake disc and extending along the width direction of the vehicle frame, the guide rail A brake caliper clamped and adapted to the brake disc is arranged on the upper side so as to be movable along its extending direction. The brake assembly has a large-range lateral movement capability, and can fully meet the working condition requirements of the rail vehicle when the gauge changes. The invention also discloses a rail vehicle using the brake assembly.

Description

Technical field[0001]The invention relates to the technical field of supporting components for a rail vehicle brake system, and in particular to a brake component. The invention also relates to a rail vehicle applying the brake assembly.Background technique[0002]At present, most of the rail vehicles in my country use standard gauges, so the bogies adopt fixed gauge bogies, that is, the distance between the two sets of wheels of the vehicle remains unchanged, and there is only a small amount between the main frame of the vehicle and the wheels Lateral displacement. However, in some areas, railway vehicles need to run continuously on tracks with different gauges. Therefore, the bogie is required to have a gauge change function, that is, the distance between the two sets of wheels can be changed according to the gauge of the track being driven.[0003]Correspondingly, the brake disc installed on the wheel set will also move with the track change of the wheel set, and the matching brake c...
