Abstract

The invention relates to the technical field of railway vehicles, and provides a railway vehicle bogie frame, a railway vehicle bogie and a railway vehicle. The railway vehicle bogie frame comprises afirst end beam, a second end beam and a box beam arranged between the first end beam and the second end beam. The box beam comprises a motor box and gear cases. The motor box is connected with the first end beam and the second end beam through the gear cases. According to the bogie frame, the motor box and the gear cases are integrated on the bogie frame, accordingly, a motor installing base, a gear case hanging rod base and other structures on an original bogie frame are eliminated, and the bogie dismounting and mounting efficiency is improved. In addition, additional arrangement of the motor box and the gear cases on the bogie frame base is not needed, accordingly, the height between a railway vehicle floor and the ground can be reduced, the distance between the railway vehicle floor ofthe railway vehicle and the ground is reduced, and the lateral rolling resisting capability of the railway vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, and provides a rail vehicle bogie frame, a rail vehicle bogie and 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 t...
