The specific embodiment
Shown in Fig. 1-2, dynamically gauge is optimized structure, the stock rail 12 of track switch 10 sections and tongue 14, and during near stock rail 12, vehicle crosses branch line, and vehicle crosses main track when tongue 14 and stock rail 12 space out at tongue.
In order to ensure at tongue 14 near stock rails 12 and when having rail vehicle to cross branch line, grasp the condition that conforms to main track, therefore and PURE ROLLING rather than creep motion between wheel and the track be described, to change the trend of stock rail by following mode near the former scope of (stock rail) in tongue 14 and peaked area 16 thereof according to the utility model.To move towards change can cause finishing PURE ROLLING when vehicle crosses branch line in order to make, it is right that rail vehicle will have such wheel, and these are taken turns tapered trend in its work plane zone, that is to say that these take turns towards end face direction tube reducing.The work plane zone is subjected to the restriction of wheel rim usually.Wheel is rigidly connected with axletree in addition.
At second section 20 that is positioned at branch line near its point of switch 21 on the tongue 14 of stock rail 12.
By the change that each wheel contact point is finished in change of moving towards of stock rail 12,, promptly be transferred on the longitudinal axis of main track or branch line so that axletree is transferred on the circuit longitudinal axis that will cross.Therefore wheel rim not taking place on tongue skids.
So not only improved comfort level by bus, and the while vehicle can cross the track switch through respective design at a high speed.Therefore the condition of circuit will appear being similar in the transitional region between stock rail and tongue.
The change of moving towards of stock rail 12 forms by a plurality of sections.First curved section 18 that therefore, 21 fronts, tongue 14 tips are just arranged on the close position of stock rail 12.Here section 18 at first has one to contain the radius of curvature that r is tending towards ∞, changes stock rail 12 over to so that can connect all the time, i.e. tongue 14 region in front.Section 18 is to finish with the terminal radius that contains the R=constant.Second section 20 of straight line is connected with first section 18.The point of switch 21 is near tongue 14 in second section 20.Second section 20 connection changes the 3rd section 22 over to, and the line alignment that this section 22 is indicated according to dashed lines 24 is provided with depression.26 of the 4th linear section are from the 3rd section 22.Tongue 14 at the 4th section 26 is to finish with the zone near stock rail 12.
Fig. 1 comes the zone of this terminal of mark to finish with reference marker 27.The 5th crooked section 28 is connected with the 4th section 26.Crooked section 28 is drawn by the 4th section 26, and a terminal radius that contains the R=constant is at first arranged, and contains the radius of curvature that r is tending towards ∞ so that can change over to subsequently, changes stock rail 12 over to so that can connect after it moves towards change all the time.
As the diagram demonstration, not only first section 18 but also the 5th section 28 all have a convexly curved trend according to line alignment 24, have the 3rd crooked section 22 to be designed to the curved shape that caves in.
The length of section 18,20,22,26,28 will have following correlation.First section 18 length L

In addition 20,22 and third and fourth sections 22,26 of second and the 3rd section all the time or basically all the time mutually smooth connection change over to.Also there is one to change over to all the time with the trend of the 5th section 18,26 curature variations in addition to being connected of stock rail 12 by first.
From Fig. 2, can draw in addition, in the 3rd section 22 scopes, the distance between the real work limit 34 of the working edge 32 of the line alignment that equals to suppose near the distance alpha between the working edge 32 of the line alignment of the real work limit 30 of stock rail on the tongue 14 of stock rail 12 and hypothesis and tongue 14.This distance alpha is 6mm.
In other words, tongue 14 has one to be the width of 12mm in certain zone in its 3rd section that section 22 distributes that moves towards according to stock rail 12 to change, and this width is along being produced by the line that is connected to form between stock rail 12 working edges and tongue 14 working edges.
The above tongue 14 of position near stock rail 12 in the 4th section 26 forms isolating construction with stock rail.
Trend by stock rail 12 changes the autotelic wheel contact point in orbit that influences, so that axletree is adjusted to all the time center line perpendicular to the circuit that will cross vehicle, so that wheel is only at stock rail with roll on tongue subsequently, and can not skid along the tongue side.
Distance road along the line between the sidewall of grooving 40 and the stock rail working edge vertically changes.
Grooving 40 is positioned on the rail head side 38 on rail inoperative limit.
Grooving 40 starts from 12mm place on the starting point that stock rail 12 sections 11 move towards change, and will be arranged on 14mm place, rail head tread bottom.
Moving towards in the mobility scale of section 11 maximums, grooving 40 has one to be the spacing of 5mm apart from the rail head tread in its interface wall parallel with the web of the rail 43.
Grooving 40 is the ledge structure designs that form through Milling Process at rail head edge 38.
Grooving 40 have a side parallel with the web of the rail 43 with one with the almost vertical bottom surface 42 of the web of the rail, this bottom surface may extend to the rail head tread.
Suppose that axletree is not in the state vertical with track centre constantly during crossing main track.And more be to produce a kind of sinusoidal motion, that is to say angle sometimes greater than 90 °, sometimes less than 90 °, but do not skid in the tongue side.Situation is like this equally when axletree crosses branch line.
If only shown a section of a stock rail and a tongue among Fig. 1, same so in principle geometric proportion or same move towards change and also can on second stock rail of track switch and tongue, realize.
