A passenger locomotive and its three-axle bogie

Abstract

The invention discloses a three-axle bogie for a passenger locomotive, which includes a frame, a motor drive unit, two end wheel sets, and an intermediate wheel set between the two end wheel sets. The motor drive unit It includes two, and one of the motor drive units is arranged on the middle wheel pair, and the other one of the motor drive units is arranged on any one of the end wheel pairs. The three-axle bogie has one less motor drive unit, which effectively reduces the overall weight of the bogie, so that the overall axle load of the locomotive is controlled within 17T, which can realize the passenger locomotive on the passenger dedicated line or the passenger dedicated line with the existing Run across lines between lines. The invention also discloses a passenger locomotive with the above-mentioned three-axle bogie.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies, in particular to a passenger locomotive and a three-axle bogie. Background technique [0002] As a key component of the rail vehicle, the bogie undertakes the task of carrying the weight of the parts above the frame and ensuring that the vehicle passes through the curve smoothly. [0003] In 2007, my country launched the sixth national railway speed increase, planned and built a number of high-speed passenger dedicated lines, and adopted advanced high-speed passenger train series EMUs, which greatly improved the convenience of national travel. However, when the new high-speed passenger line was merged into the existing railway network, it was found that the existing high-speed passenger locomotives in my country could not operate on the newly-built high-speed passenger dedicated line. It cannot meet the requirements of new passenger dedicated lines, thus causing a waste of high-speed ...

AI Technical Summary

Problems solved by technology

However, when the new high-speed passenger line was merged into the existing railway network, it was found that the existing high-speed passenger locomotives in my country could not operate on the newly-built high-speed passenger dedicated line. It cannot meet the requirements of new passenger dedicated lines, resulting in a waste of high-speed passenger line resources and hindering the development of railway transportation

[0004] According to regulations, the axle load of a vehicle running on a high-speed passenger dedicated line cannot exceed 17T. However, there is currently no electric locomotive in my country that can run on a passenger dedicated line or cross-line between an existing line and a passenger dedicated line. The bogie technology is relatively mature, but the axle load of locomotives using these bogies is above 20T, and it is difficult to control the axle load within 17T, so it is impossible to run on high-speed passenger lines or between high-speed passenger lines and existing lines
