Embodiment Construction

[0031] The bogie of the invention has a high-speed internal combustion locomotive three-axle bogie with high running speed, excellent curve passing performance and a running speed of 160km / h.

[0032] The composition of bogie of the present invention is: frame, wheelset, driving device, braking device, primary suspension device, support assembly, traction device, accessory assembly and wheel rim lubrication etc.

[0033] The bogie adopts the Co-Co shaft type, and the traction motor of the driving device adopts the parallel arrangement, which can effectively reduce the axle load transfer and improve the adhesion utilization rate of the locomotive. The bogie adopts the matching method of the first series of axle box springs with higher vertical stiffness, the second series of high round springs with smaller vertical stiffness, the first series of vertical shock absorbers, and the second series of vertical shock absorbers. While meeting the requirements of the frame suspension an...

Abstract

The invention discloses a quasi-high speed broad-gauge triaxial internal combustion locomotive bogie which comprises a bogie frame, a wheel pair, a drive device, a brake device, a single stage suspension device, a supporting assembly, a traction device, an accessory assembly, a rim lubrication device and the like, the vertical stability of a locomotive is improved, and the dynamic acting force of the locomotive on a line is reduced. A hollow shaft two-pole transmission structure and a drive device suspension structural mode are adopted in the broad-gauge bogie drive device, and the running speed of the broad-gauge internal combustion locomotive can be improved. The bogie is suitable for the requirement of broad-gauge line countries for improving the running speed of internal combustion locomotives.

Description

technical field [0001] The invention relates to the technical field of a wide-gauge three-axle diesel locomotive bogie. Background technique [0002] Most of the railway gauges in our country are international standard gauges (1435mm), but there are many gauges in the world, including meter gauge, 1067mm gauge, 1520mm gauge, and 1676mm gauge. If our railway products want to enter the world market, we must have products that meet the different requirements of different countries. At present, from a global perspective, countries that adopt wide-gauge systems have more demand for locomotives, including Pakistan, Argentina, and the Commonwealth of Independent States, which requires us to develop wide-gauge system locomotives. [0003] The bogie is an important part of locomotive operation, and its structure directly determines the running speed, running safety, running quality and comfort of the locomotive. Therefore, the first focus of developing locomotives with different ga...
