Specific embodiments

Reference numeral implication: rail level 1, rail hat 2, rail chair 3, tenon 4, fourth of the twelve Earthly Branches groove 5, tenon peak 6, fourth of the twelve Earthly Branches bottom land 7, tenon root 8, fourth of the twelve Earthly Branches notch 9, forward finedraw 10, fixed bolt hole 11, gusset plate 12.

Convert lateral clearance into the forward method of finedraw: lateral clearance is divided into several perpendicular forward adjacent little rectangles; The length of rectangle equals the width of lateral clearance; The quantity that the width of rectangle multiply by rectangle equals the length of lateral clearance, and is as shown in Figure 1; Each little rectangle is parallel mobile to a side, lets the one of which angle link to each other with an oblique line and evenly extension, and is as shown in Figure 2; It is again toward inflection, as shown in Figure 3 when the position between each rectangle meets the requirements; When first little rectangle is got back to the origin-location, change and finish, as shown in Figure 4.

The direction of little rectangle is along the direction of rail, so for forward, in the reality, the width of little rectangle only is equivalent to 1/tens of lateral clearance width, so claim finedraw.The major reason that does not have bump, do not shake when forward, finedraw is train wheel process Rail joint head.

The position of the similar isosceles triangle that as stated above, each little rectangle on the rail is moved and is rotarily formed along oblique line is called tenon or fourth of the twelve Earthly Branches groove.

Per two connectors that match constitute one group when connecting rail; A connector has some sizes and the identical tenon of shape; Another then has equal number and corresponding with it fourth of the twelve Earthly Branches groove; Between the tenon, between the groove of the fourth of the twelve Earthly Branches, between tenon and the fourth of the twelve Earthly Branches groove, and various relations such as tenon fourth of the twelve Earthly Branches groove is corresponding with position, direction and interlock between the rail joint, like Fig. 5, shown in Figure 6.
