Description
Technical field
The present invention relates to Heavy-Haul Railway freight locomotive field, be specially a kind of locomotive three axle radial bogies.
Background technology
Railway locomotive steering, when by curve, must rely on wheel rim to guide to guarantee that bogie truck is along rail running.Now, between rail side and wheel rim, lateral contact occurring, pushes, rubs in surface, causes wheel track to produce abrasion.The influence factor of abrasion is mainly that wheel is to the angle of attack, wheel-rail lateral force.Common engine truck wheel be to rotating with respect to framework, therefore when by curve track, wheel to and track between the larger angle of attack of formation, thereby produce additional wheel-rail wear, radius of curve is less, this situation is more obvious.For Heavy-haul Freight three axle truck, because axle is great, wheel is large to locating stiffness, wheelbase is long, therefore large to the angle of attack by curve hour wheel, wheel-rail lateral force is large, wheel-rail wear is more serious, causes the maintenance cost of locomotive and circuit all very high.Therefore, the wheel while managing to reduce locomotive curve negotiating, to the angle of attack and wheel-rail lateral force, reduces wheeling edge wearing, to reducing the operation maintenance cost of railway locomotive, has great importance.
Radial steering divides self-steering radial truck and forced-steering radial truck, and wherein self guide mechanism is relatively simple, applies wider.As far back as 20 century 70s, foreign railway vehicle starts to adopt radial steering technology.The development of Self-Steering Power Bogie far lags behind the bogie of car, and to beginning of the nineties late 1980s, breaking through just appears in its technology.
The domestic starting of the research at radial steering is more late, just on vehicle and diesel locomotive, developed radial steering in recent years, and the tentative entrucking of having carried out small lot is used, as Chinese invention patent publication number CN03148640.1 discloses a kind of radial steering with being arranged on the modularity drg on steering beam, it comprises: framework, front-wheel to trailing wheel to, the first steering beam and the second steering beam, traction link, between centers drag link mechanism, be arranged on the drg of the modularity on the first and second steering beams." shipping diesel-electric locomotive HTCR bogie truck " that paper " development of DF8B type locomotive radial steering ", the workman > > of < < rolling stock magazine 12 phases of nineteen ninety-five of delivering on < < experimental study > > magazine deliver all relates to a kind of diesel locomotive three axle radial bogies, and its structure is basically identical with invention CN03148640.1.Electric locomotive radial steering does not have exploitation and application.
