Description
Technical field
The invention relates to a kind of wheel for track, especially a kind of wheel rim and tread are the wheel for track of split-type structural.
Background technology
In the prior art, the wheel rim of rail wheel part (tread and wheel rim) is to be one-piece construction.Wheel is on curve or in the straight-line guidance walking process, described wheel tread contacts with the end face of described track, and carry out rolling movement with respect to rail top face, described wheel rim then is positioned at the side of described track, because wheel rim is bigger than tread diameter, the wheel rim that whenever circles than the tread straight length of passing by more.That is, when wheel rolling moves, when described wheel rim contacts with track side surfaces, must produce wheeling edge wearing with the track slide relative.When wheel rolled in orbit, tread was a pure rolling, and wheel rim and track side surfaces can produce slide relative, so wheeling edge wearing is than big many of tread.Because wheel rim play the guiding role in wheel travels, so during break-in, all can frequently contact with track side surfaces in guiding on the straight line or on curve.The wheel rim wear down is to a certain degree will repairing by Xuan, and the major part of wheel all is because wheel rim wear down and Xuan falls.
In order to solve the problem of wheeling edge wearing, in the prior art, mainly adopt following method:
One, edge is lubricated
This know-why is grease to be sprayed or is coated in reduce wheel rim and track friction on the wheel rim, and its disadvantage is: consume grease and locomotive kinetic energy, contaminated environment descends tread and interorbital friction coefficient and generation driving wheel skid.
Two, taper tread structure
As shown in Figure 1, this technology is that the tread 1 ' with every pair of wheel all forms taper, promptly wheel tread 1 ' towards the inside diameter of car body center position (promptly near wheel rim 2 ' direction) greater than outside diameter towards the car body lateral direction.Its principle of work is to utilize the automatic centering power of the taper tread 1 ' of two wheels to reduce application force between wheel rim 2 ' and the track 3 '.Its disadvantage is that vehicle can produce hunting.Produced the worn profiled wheel tread structure on this basis again, as shown in Figure 2, this know-why is the taper tread 1 with two wheels " make the shape after the abrasion, reduce the application force between wheel rim 2 ' and the track 3 '.This texture ratio taper tread structure is progressive to some extent, but still can not solve the wheeling edge wearing problems of too at all.
Three, radial steering
This know-why makes axis alignment center of turn (radius of curve center) for utilizing mechanism, reduces the angle of attack of wheel rim relative orbit, but can not solve the slide relative of wheel rim and track at all.On straight line, do not act on and the installation cost costliness.
Four, bogie truck cross-connecting apparatus
This know-why, as shown in Figure 3, for utilizing the cross-connecting apparatus 4 ' that constitutes by elastic mechanism that trailing or leading bogie 5 ', 6 ' is linked together, utilize the mutual action of trailing or leading bogie 5 ', 6 ' outer corner difference to reduce the angle of attack of wheel rim relative orbit, but still can not solve the slide relative of wheel rim and track at all.Not effect on straight line.Because the wheelbase of three axle bogies is long, and is big by radius of curve, and the wheelbase of two axle bogies is shorter, little by radius of curve, so this bogie truck cross-connecting apparatus can only be used on two axle bogies, can not be used on three axle bogies.Only have in indivedual electric locomotives in practice and used, be not widely used.
Summary of the invention
The objective of the invention is to provide a kind of and can overcome the prior art defective, when avoiding wheel rim to contact, produce the wheel for track that slide relative causes wheeling edge wearing with track with track.
For this reason, the invention provides a kind of wheel for track, described wheel comprises wheel body and wheel rim, the periphery of described wheel body constitutes the tread that contacts with described track, described wheel body one side is provided with the wheel rim of external diameter greater than described tread external diameter, wherein, described wheel rim and described wheel body are split-type structural, and described wheel rim can be dismantled, also be arranged on rotationally on the periphery of described wheel body; One rib is positioned at the outside of described wheel body and wheel rim, is fixed on the wheel body by a connecting element.
