Abstract
The utility model discloses a radial mechanism for a locomotive bogie, relating to the field of locomotive vehicle structure design. The radial mechanism comprises a bogie shaft, rotating beams, axle box pulling rods and a coupling rod, wherein a front rotating beam is connected with a front axle of the bogie by a front axle box pulling rod; a rear rotating beam is connected with a rear axle of the bogie by a rear axle box pulling rod; the left end of the coupling rod is hinged with one end of a front rotating beam connecting rod; the other end of the front rotating beam connecting rod is hinged with the left end of the front rotating beam; the middle part of the coupling rod is hinged with one end of a rear rotating beam connecting rod; the other end of the rear rotating beam connecting rod is hinged with the right end of the rear rotating beam, therefore, the linkage of wheel pairs is realized. When a locomotive passes by a curve, the creep guide moment between wheel tracks lead the wheel pair of the front axle of the bogie to obtain the radial position; and under the action of a steering mechanism, two end axles of the bogie can obtain radial positions respectively when passing by curves with different curvature radius, therefore, the action force between a wheel and the track can be reduced, and the locomotive can be ensured to successfully pass the small-radius curve.
Description
Technical field
The utility model relates to rolling stock structure design field, is specially a kind of radial mechanism of locomotive bogie, is applied on the rolling stock bogie truck.
Background technology
China is vast in territory, and hills and mountain area proportion are very big, and the railroad curve in mountain area is many and bending spring is little, has limited the running velocity of rolling stock.Development locomotive radial steering technology can improve vehicle by running velocity on the elbow curve and the wearing and tearing that alleviate wheel, rail, reduces the railroad maintenance cost.Self guide mechanism is a gordian technique of radial steering, effect by self guide mechanism can reduce the right angle of attack of wheel, thereby make wheel-rail lateral force each take turns between reasonably distributed, make front and back wheel to by curve the time, having the radial position ability that is tending towards curve simultaneously, thus the stability when improving rolling stock greatly by curve.The present invention is contained in three diameters of axle on the vehicle to mechanism for a kind of, and great realistic meaning will be arranged.
In recent years, various countries competitively carry out the radially research of bogie truck, have obtained certain effect, have begun to enter practical stage, and this respect development mainly contains countries such as the U.S., Germany, Switzerland, South Africa than faster.
Current, the wheel of the most of rolling stock that travels on China's circuit is bordering on being connected of rigidity to still adopting in the vertical with framework, and promptly front and back wheel is parallel to remaining in the operational process.When rolling stock when the curve track, wheel is to the position of keeping parallelism still in framework, make wheel to and track between the angle of attack bigger, produce bigger transverse force between wheel track, thereby wheel-rail wear is serious, rolling stock adhesive performance on curve descends.Solve this contradiction, adopting the radial steering technology is a desirable approach.
The self guide mechanism bogie truck is the guiding mechanism that utilizes front and back wheel right, the motion of shaking the head that front and back wheel is right is coupled together, utilize vertical creep power of left and right wheels poor, front-wheel is right to by the curve hour wheel trend that is tending towards radial position oppositely being sent to trailing wheel, make front and back wheel to by curve the time, all being tending towards the curve radial position, reduce the wheel track horizontal force to reach, reduce to take turns purpose the angle of attack and wheel-rail wear.
Chinese patent CN200720129909.2 discloses a kind of passenger car bogie radial guide means, and its composition comprises: two pilot bars, mount pad, guiding damper, guiding damper seat.
U.S. Pat 4679506 discloses locomotive (the Railway truck with improved steering linkage of a kind of improved steering swivel system, detachable suspension and traction motor braking, detachable suspension and traction motor mounted brake), its structure is: the right side wheel of front-wheel links together to axle box by pull bar and the trailing wheel wheel to the same side to axle box, realizes interlock.
Yet before, during and after still can not limiting effectively in above-mentioned two kinds of guide piece structures the wheel to vertical relative displacement, before, during and after being easy to generate wheel between the motion of shaking the head relatively, cause train guiding mechanism when high-speed cruising to produce fierce vibration, wheel-rail wear and tear is serious.
Chinese patent CN03148641.X discloses a kind of radial steering device, its structure is as follows: preceding steering beam links together to axle box by pull bar left and right wheel that front-wheel is right, and back steering beam links together to axle box by pull bar left and right wheel that trailing wheel is right.Two steering beams link together by a big pull bar (being equivalent to coupling bar of the present utility model) again, thus realize front and rear wheel to interlock.
Chinese patent CN03148641.X also discloses a kind of radial steering device, it comprises framework, front and rear wheel to forward and backward bogie axle, and the forward and backward steering beam that links to each other with forward and backward bogie axle by pull bar respectively, in one wheel to and middle bogie axle, the between centers pull bar (being equivalent to coupling bar of the present utility model) of steering beam and back steering beam before connection.Two steering beams link together by a between centers pull bar again, thus realize front and rear wheel to interlock.
This patent limit to a certain extent front and rear wheel to vertical relative displacement, yet it is because only grade coupled by one, when bend front and rear wheel between still be easy to generate by a relatively large margin the motion of shaking the head relatively, cause train guiding mechanism when high-speed cruising to produce fierce vibration, wheel-rail wear and tear is serious.
Summary of the invention
For overcome existing radial mechanism of locomotive bogie be easy to generate when the bend front and back wheel between the motion of shaking the head relatively, cause train guiding mechanism when high-speed cruising to produce fierce vibration, the wheel-rail wear and tear class-one defect, the utility model aims to provide a kind of radial mechanism of locomotive bogie, it is by the effect of rotating mechanism, make the bogie truck two end axles when the curve by different curvature radius, can obtain radial position separately, reduce the application force of wheel and track, guarantee that locomotive can pass through sharp radius curve smoothly.
