Abstract

The invention relates to the field of vehicle variable gauges, and provides a variable gauge bogie frame and a variable gauge bogie, wherein side beams are arranged in parallel, and the cross beams are connected between the side beams and arranged in parallel; brake clamp locking seats are respectively arranged on the inner side of each side beam and on the outer sides of the pair of cross beams;the brake clamp locking seat is of a box-shaped structure; an upper top plate of the side beam extends inwards to form an upper cover plate of the brake clamp locking seat, and a side plate of the brake clamp locking seat is welded with the bottom plate and then welded with the upper cover plate to form the box-shaped structure; active anti-yaw damper mounting bases are arranged at the two ends ofone cross beam and located on the outer sides of the side beams correspondingly. By redesigning the structure of the framework, the installation requirements of a variable gauge wheel set can be met.

Description

technical field [0001] The invention relates to the technical field of track-gauge variable rail vehicles, in particular to a variable-gauge bogie frame and a variable-gauge bogie. Background technique [0002] In order to meet the transportation requirements between tracks of different gauges in neighboring countries, bogies with different inner distances of wheel sets are often replaced at the junction. This solution is costly and time-consuming. Spain and Japan successively invented variable-gauge bogies, and the wheel sets can run continuously between tracks of different gauges. [0003] In order to adapt to the requirement of changing the gauge of the wheel set, the existing bogie frame has been unable to meet the requirement of changing the gauge. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0006] The object of ...
