Abstract

The invention relates to the technical field of railway vehicles, and provides a bogie framework of a railway vehicle and a bogie. The bogie framework of the railway vehicle comprises a first end beam, a second end beam and a box beam. The box beam comprises a first-level gear case and a second-level gear case. The first-level gear case is used for connecting a traction motor and the second-levelgear case. The second-level gear case is arranged between the first-level gear case and the first end beam and between the first-level gear case and the second end beam. The gear cases are integratedon the bogie framework, the bogie dismounting and mounting efficiency can be improved, the height from a railway vehicle floor to the ground is reduced, the distance between the railway vehicle floorof the railway vehicle and the ground is reduced, and meanwhile the lateral rolling resisting capability of the railway vehicle is improved. Furthermore, due to the integrated design of the gear casesand the bogie framework and gear transmission inner arrangement, the height of the bogie can be better reduced, the requirements of suburb elevated, urban tunnels and A type subway tunnel shields aremet, and the engineering manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a bogie frame and a bogie of a rail vehicle. Background technique [0002] As an important part of a rail vehicle, the bogie frame directly determines the dynamic performance and safety performance of the rail vehicle. The bogie frame in the prior art is formed with a motor mounting seat and a gear box boom seat, and the installation of the motor and the gearbox is realized through the motor mounting seat and the gear box boom seat respectively. The technical problem of this kind of bogie frame in the prior art is that, due to the need to additionally set the motor mounting seat and the gear box suspender seat, the efficiency of disassembling and assembling of the bogie is low. Moreover, after the motor and the gearbox are installed on the bogie frame, the height under the vehicle will be too high, that is, the floor of the rail vehicle is higher than the ground, which is ...
