Single-unit eight-axle electric transmission shunting diesel locomotive

Abstract

The invention discloses a single-unit eight-axle electric transmission shunting diesel locomotive. The locomotive is divided into an upper part and a lower part; the upper part is a car body with a frame, two ends of the lower part are bogies which include two B0-B0 four-axle bogies, and each of the two B0-B0 four-axle bogies is formed by that two B0 two-axle bogies and a transition frame are connected by rubber pads, and the transition frame is arranged at the middle above the two B0 two-axle bogies; and the car body is connected with the B0 two-axle bogies through a transition device. The single-unit eight-axle electric transmission shunting diesel locomotive has the advantages that the transition capacity is high; parts have good generality, the maintenance is convenient, and the locomotive maintenance cost is reduced; the locomotive has good curve negotiating performance, and the wheel / rail abrasion value is greatly reduced; only one set of diesel, generator and cooling device are used, the reliability and the economy of the locomotive are improved, and the production and use cost is reduced; and the application economical efficiency is high, the single-unit eight-axle locomotive can replace two four-axle locomotives, the number of the locomotive crew is reduced, and the use is convenient.

Description

technical field [0001] The invention relates to a diesel locomotive, in particular to a single-section eight-axis electric transmission shunting diesel locomotive used for shunting operations and small running operations in a yard, and belongs to the technical field of diesel locomotives for rail transit. [0002] Background technique [0003] Due to the increasing passenger and cargo volume in the railway transportation of countries all over the world, measures such as increasing the weight of the train and increasing the speed of the train are generally adopted to meet the transportation requirements. Therefore, the power of the locomotive must be increased. In addition to increasing the single-shaft power, under the existing load conditions, it is required to increase the number of moving axles of the locomotive. In many small and medium-sized countries, the number of single-section locomotives has been increased from 4 to 6 axles. Now, most countries in the world have d...
