Abstract

The invention relates to a rail locomotive vehicle low-floor bogie, in particular to a low-floor bogie driving unit and a low-floor bogie. A driving motor (1) of the driving unit, a first gear box (3) used for driving a first wheel pair and a second gear box (5) used for driving a second wheel pair are installed on the outer side of a bogie frame (7), the driving motor is vertically installed, the first gear box and the second gear box are connected through a connecting rod device (4), a second transmission gear is installed at one end of the connecting rod device, and a second transmission gear is installed at the other end of the connecting rod device. The output shaft of the driving motor is connected with and drives the first transmission gear, the second transmission gear is meshed with the input gear in the first gear box, and the third transmission gear is meshed with the input gear in the second gear box. According to the invention, the transverse space required by the installation of the driving motor is reduced, the junction points of the output shaft of the motor are reduced, and the maintenance cost is effectively reduced.

Description

technical field [0001] The invention relates to a low-floor bogie of a rail vehicle, in particular to a low-floor bogie driving unit and a low-floor bogie. Background technique [0002] At present, there are two main arrangements of drive units used in low-floor vehicle bogies in the world, namely, the motor transverse (track width direction) arrangement and the motor longitudinal (track length direction) arrangement. The drive units with the motor transversely arranged and the motor longitudinally arranged are installed in the bogie frame, and the drive unit with the motor transversely arranged needs to be used in conjunction with the transmission wheel pair, which is limited by the size of the wheels, which is not conducive to reducing the height of the middle of the bogie to achieve real meaning The drive unit arranged in the longitudinal direction of the motor can reduce the space required for the lateral installation of the motor. By using it with the bogie axle bridge,...
