Swing bolster and bogie

Abstract

The invention provides a swing bolster and a bogie. The swing bolster comprises a swing bolster body, wherein the middle of the swing bolster body is recessed downwards; the two ends of the swing bolster body are two-series spring mounting seats; the swing bolster further comprises swing bolster lifting seats arranged on the front side face of the swing bolster body in the recessing direction; theadjacent side of each two-series spring mounting seat is provided with the corresponding swing bolster lifting seat; and the swing bolster lifting seats protrude along the two ends in the width direction of the swing bolster. Compared with the related art, the swing bolster has the advantages that the functions of integrated bearing connection, integral hoisting, transverse stop mounting seats, air spring overcharging limiting and the like are integrated, the whole vehicle mounting space and the design space of the bogie are saved, the integral hoisting safety is improved, and the maintenanceand operation costs are greatly reduced.

Description

technical field [0001] The invention relates to the design of a rail vehicle bogie frame, in particular to a bolster and a bogie. Background technique [0002] At present, the bogies of most rail vehicles are all provided with separate integral hoisting wire rope devices (such as a kind of maglev rail vehicle and its bogies disclosed in the current patent CN106476832A), or the structure of the latch realizes lifting (such as the publicity of the current patent CN209553199U) bogie integral hoisting device), all of which are complex in structure and easy to wear, which greatly threatens the safety of bogie and car body lifting, and today's bogie design has higher requirements for compact structure and lightweight. [0003] As the bolster disclosed by the patent CN206465940U, it is impossible to realize integral lifting. [0004] In addition, regarding the nouns of orientation mentioned in this case, those skilled in the art generally believe that: [0005] The front side of ...
