Embodiment Construction

[0013] The structure of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, in the figure: 1- traction seat at the bottom of the vehicle; 2- draw bar; 3- wheel pair; 4- driving device; 1st-series vertical shock absorber; 9-secondary transverse shock absorber; 11-secondary vertical shock absorber; 12-secondary spring; 13-anti-snake shock absorber; 15-frame, 16-drive motor. The bogie adopts the matching of primary springs 6 hard and secondary springs 12 soft and long single drawbar 2; the front and rear wheel pairs of the bogie are power-driven wheel pairs, and the driving units of the front and rear wheel pairs have the same structure and are obliquely symmetrical to the center of the bogie Arrangement, the driving unit is mainly made up of the driving device 4 and the driving motor 16 that drives the driving device. The middle wheel pair does not have a driving device, but a ...

Abstract

The invention discloses an A1A shaft type elastic suspension turning frame for a high speed locomotive. A three-axle turning frame is adopted; the shaft type is in an A1A structure mode, namely a front and rear wheel pair is a driving wheel pair with driving devices and a middle wheel pair is not provided with driving devices; driving units of the front and rear driving wheel pair are oppositely arranged on the front and rear wheel pair in a diagonally symmetric manner; and each driving unit is suspended on a framework through three points, namely a rubber joint and an oscillating bar pair consisting of two oscillating bars. By the structure of the turning frame, lower axle weight, smaller axle distance and higher axle power can be realized; due to the elastic suspension of an end axle driving system of the turning frame, the dynamics of high speed running of the locomotive can be enhanced effectively; furthermore, the performance of the turning frame meets the requirement that two locomotives can drag 16 to 18 sections of passenger trains and run on 300-km / h railway lines special for passenger traffic and existing acceleration lines at a speed of 200 to 250 km / h or railway lines special for passenger traffic in an overline manner.

Description

technical field [0001] The invention belongs to the technical field of manufacturing railway locomotives, especially high-speed locomotive bogies. Background technique [0002] my country's medium and long-term railway network planning will build about 12,000 kilometers of dedicated passenger lines with a speed of more than 200km / h. Some of the lines will run 300km / h high-speed trains. In order to economically and effectively play the role of the passenger transport network, the 300km / h passenger dedicated line will run two trains at 300km / h and 200-250km / h at the same time. This requires that 200-250km / h passenger trains can run on the 200-250km / h passenger dedicated line, and can run across the 300km / h high-speed dedicated line. [0003] Our country has a vast territory. For long-distance passenger transportation and passenger transportation at night and morning, the formation of high-speed locomotives to pull passenger cars (or power-concentrated EMUs) is more expensive...
