Description

A kind of three axle radial bogie of locomotive
Technical field
The present invention relates to Heavy-Haul Railway freight locomotive field, specially a kind of three axle radial bogie of locomotive.
Background technology
Railway locomotive steering is when by curve, it is necessary to guide to ensure bogie along track row by wheel rim Sail.Now, occur laterally to contact between rail side and wheel rim, surface occurs extruding, friction, causes wheel track to produce mill Consumption.The influence factor of abrasion is mainly taken turns to the angle of attack, wheel-rail lateral force.Common engine truck wheel to be can not be relative to structure What frame was rotated, therefore when by curve track, take turns to the larger angle of attack is formed between track, so as to produce additional wheel track Abrasion, sweep are less, and such case is more obvious.For Heavy-haul Freight three-axle bogie, as axle is great, wheel is to fixed Position rigidity is big, wheelbase is long, therefore by curve hour wheel is big to the angle of attack, wheel-rail lateral force is big, wheel-rail wear causes machine than more serious The maintenance cost of car and circuit is all very high.Therefore, wheel when trying to reduce locomotive curve negotiating to the angle of attack and wheel-rail lateral force, drop Low wheeling edge wearing, the operation maintenance cost to reducing railway locomotive have great importance.
Radial steering point self steering radial truck and forced steering radial truck, wherein self guide mechanism are relatively simple Single, application is wider.Early in 20 century 70s, foreign railway vehicle starts using radial steering technology.Locomotive is radially turned to The development of frame lags far behind the bogie of car, and to beginning of the nineties late 1980s, breaking through just occurs in its technology.
The domestic research starting in radial steering is more late, just develops on vehicle and diesel locomotive in recent years and radially turns To frame, and the tentative operation on locomotive of small lot is carried out, such as Chinese invention patent publication number CN03148640.1 discloses one The radial steering with the blocking brake on steering beam is planted, which includes:Framework, front-wheel to and trailing wheel to, One steering beam and the second steering beam, traction link, between centers drag link mechanism, blocking on the first and second steering beams Brake.《Experimentation》The paper " development of DF8B type Self-Steering Power Bogies " delivered on magazine,《Rolling stock Workman》" the shipping diesel-electric locomotive HTCR bogies " that 12 phase of magazine nineteen ninety-five delivers all refers to a kind of three axle of diesel locomotive Radial steering, its structure are basically identical with invention CN03148640.1.And electric locomotive radial steering then do not have exploitation and Using.
The content of the invention
For the above-mentioned deficiency of prior art, the present invention is intended to provide a kind of three axle radial bogie of locomotive, the bogie Radial device is set on conventional power locomotive three-axle bogie, to ensure bogie in curve negotiating, reduces wheel to the angle of attack, Wheel-rail lateral force is reduced, so as to reduce wheel-rail wear, improves the curving performance of locomotive, reduce wheeling edge wearing and cross force, Train is improved simultaneously by speed during curve.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of three axle radial bogie of locomotive, mainly by three wheels to axle box assembling, three sets of driver elements, framework, A set of single stage suspension device, a set of secondary suspension device, a set of traction apparatuss, three sets of suspension device of motor, a set of brake unit, A set of radial device composition;The framework is mainly made up of front beam, two curb girders, draw beam, intermediate transverse girder, back end beam;It is described Framework is provided with multiple erection supports;Three wheel is divided into an axle axial assembling positioned at front side, position to axle box assembling In three axle axial assemblings of rear side, and two between an axle axial assembling and three axle axial assemblings Axle axial is assembled;Which is structurally characterized in that, is mounted in the radial device of bogie bottom mainly by pivot, front guide beam, mistake Cross coupling pull bar, support bar, connecting lever, coupling pull bar, rear guide beam composition;Between the front guide beam and framework front beam, institute State;The front guide beam can be turned around pivot with rear guide beam It is dynamic;The transition coupling pull bar is arranged between front guide beam and connecting lever;The support bar is used to support the transition coupling to draw Bar;The connecting lever is arranged on the lower seat of framework intermediate transverse girder, and can relative seat rotation;The coupling pull bar is arranged on Between connecting lever and rear guide beam.
Thus, when bogie passes through curve(It is assumed to be positive moving ahead), the wheel of axle axial assembling to Rotation passes sequentially through front guide beam, transition coupling pull bar, connecting lever, coupling pull bar, rear guide beam and is delivered to three axle axial groups The wheel of dress is right, makes the wheel of three axle axial assemblings to rotating backward so that bogie is respectively taken turns to tending to radial direction position simultaneously Put, reduction wheel is reached to the angle of attack, so as to obtain the effect for reducing wheeling edge wearing.
It is below the technical scheme of further improvement of the present invention:
