Problems solved by technology

[0004] The traction motor and gearbox of traditional electric locomotives are generally suspended on the bogie frame. One traction motor and gearbox can only drive one wheel set. Due to the influence of the lower limit of the locomotive, the transmission ratio that can be achieved is limited. To achieve a larger The traction force of the locomotive can only increase the number of traction motors, and the corresponding converter modules will increase, which will increase the material consumption cost of the locomotive

Abstract

The invention relates to the technical field of locomotive traction, and particularly relates to a traction transmission device for a locomotive. The device is in transmission connection with the locomotive, is positioned between two bogies at the bottom of the locomotive, is hoisted at the bottom of a locomotive frame, and comprises a traction transmission gear box in transmission connection withlocomotive wheel sets and a traction motor in transmission connection with the traction transmission gear box. According to the invention, all wheel sets of the locomotive are driven and the tractionforce of the locomotive is relatively large by adopting a relatively small number of traction motors; and the device is installed at the bottom of the locomotive frame, does not occupy the upper space, and does not affect the arrangement of locomotive upper equipment.

Description

technical field [0001] The invention relates to the technical field of locomotive traction transmission, in particular to a traction transmission device for a locomotive. Background technique [0002] The traction motor of a traditional electric transmission locomotive converts the torque and speed of the traction motor to the wheels through the gearbox or gear cover installed on the locomotive bogie frame. The traction motor and the gearbox are installed on the frame and the axle. The traction motor is configured with a gearbox to drive a wheel set. [0003] The diesel engine power of a traditional hydraulic transmission locomotive transmits torque and speed to the locomotive wheelset through a hydraulic transmission box integrated with a hydraulic torque converter and gear transmission. [0004] The traction motor and gearbox of traditional electric locomotives are generally suspended on the bogie frame. One traction motor and gearbox can only drive one wheel set. Due to ...
