Abstract
The utility model relates to a vibrationless rail which can relieve the damage caused by the gap of the two rails laid down presently. The utility model is characterized in that the gap joints of the two ends of each rail are matched to connect the cross section which has the included angle smaller than 90DEG with the vertical plane in the direction of the rail or the uneven and ladder-like break joint. The steel rail is utilized, as if the train runs in a seamless steel rail in a high speed, has stability, energy saving without noise, and the service life of the rail and the vehicle can be extend.
Description
The utility model relates to the friction railway track that changes present railway track end surface shape.
The rail end face of railway use at present all is perpendicular to the cross section of rail direction vertical plane, and make the rail distortion for fear of expanding with heat and contract with cold, leave certain slit at two rail intersections, like this when train vibration influence, wheel not only can produce vibrations and noise when stitching through this, and rail and locomotive etc. all had infringement, influenced raising and the safety maintenance and the conserve energy of the speed of a motor vehicle.
The purpose of this utility model is for avoiding above-mentioned weak point of the prior art, a kind of the rail end face is cast cross section or the concavo-convex and scalariform cross section that certain angle is arranged with rail direction vertical plane and design, and becomes vibrationless railway track.
The purpose of this utility model can reach by following measure:
The both ends of the surface of rail be with the vertical plane 4 angle α of rail direction less than 90 ° and perpendicular to the cross section of rail level.
The rail both ends of the surface can for the vertical plane 4 angle α of rail direction less than 90 ° and perpendicular to the cross section that parallels of rail level, the rail rail level is a parallelogram.
The rail both ends of the surface also can for the vertical plane 4 angle α of rail direction less than 90 ° and perpendicular to the cross section that intersects of rail level, the rail rail level is trapezoidal.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is the described friction rail of claim 2 an end clearance fit structure schematic diagram.
Fig. 2 is the rail perspective view of the described friction rail of claim 2 parallel end faces form.
Fig. 3 is the described friction rail of claim 3 an end clearance fit structure schematic diagram.
Fig. 4 is the intersect rail perspective view of end pattern of the described friction rail of claim 3.
Among the figure: 1-rail face, 2-rail waist, 3-two rails R-joining crack, the vertical plane of 4-rail direction.
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Embodiment 1:
Angled end-face: end face angle α=45 ° are example, as shown in Figure 1, change the rail of present two end sections and cast both ends of the surface for the rail of rail direction vertical plane angle α=45 °, it when being used an oblique slit crack 3, because wheel line all the time is cut in rail face 1 when wheel crosses gap, wheel always has true the contact with rail, and unlike the rail that uses now, vibration has been avoided in the sagging slit of the section of having.
The utility model compared with prior art has following advantage:
1, train is steady at the utility model rail going, at a high speed, and ride comfort, noiselessness, energy savings.
2, can prolong the service life of the parts such as rail, locomotive, the vibrations of train and roadbed improve the speed of a motor vehicle in the reduction train operation, energy savings, and traffic safety is convenient to railway maintenance.
Claims (3)
1, a kind of friction railway track is characterized in that: the both ends of the surface of rail for the vertical plane 4 angle α of rail direction less than 90 ° and perpendicular to the cross section of rail level.
2, friction railway track according to claim 1 is characterized in that: the rail both ends of the surface can for the vertical plane 4 angle α of rail direction less than 90 ° and perpendicular to the cross section that parallels of rail level, the rail rail level is a parallelogram.
3, friction railway track according to claim 1 is characterized in that: the rail both ends of the surface also can for the vertical plane 4 angle α of rail direction less than 90 ° and perpendicular to the cross section that intersects of rail level, the rail rail level is trapezoidal.
