[0002] Now, the variable rail mode of most rail transit is to drive the rail variable by the separate control mode. The variable rail principle of the existing rail transit is briefly described as follows: there is a circle of disc larger than the radius of the wheel in the inner side of the wheel of the carriage, which is called "wheel rim". Since the wheels on both sides are symmetrical, the "wheel rim" of the wheel is clamped in the inner side of the two rails, so that the wheel can always run on the rail without derailing, and the direction of the rail vehicle operation is controlled. When it is needed to change the rail on which the carriage runs, only the position of the "wheel rim" of the wheel is changed. For this purpose, when the rail is changed, the switch machine installed on the switch rail drives the connecting rod to the rail tip to make the back and forth switching action, so as to realize the adhesion or separation of the rail tip to the two tracks, thereby realizing the function of changing the vehicle running on different rails.

[0027] Working principle:
[0028] like Figure 2 As shown, in this embodiment, the deflection track is configured for right turns;
[0029] When rail vehicle 1 turns from the straight track to the turning track, the hydraulic cylinder on the right side drives the limiting wheel 14 to move downward. The limiting wheel 14 comes into contact with the outer side of the first straight track section 61 of the second parallel track 6. At this time, the two sides of the right travel wheel 4 are limited on the first straight track section 61 by the wheel flange 42 and the limiting wheel 14, so that the right travel wheel 4 travels from the first straight track section 61 along the inner turning track 7, thereby causing rail vehicle 1 and the left travel wheel 4 to turn as well. When the left travel wheel 4 transitions from the first parallel track 5 to the first turning track section 81, the left travel wheel 4...

After the turn is completed, the hydraulic cylinder on the right drives the limit wheel 14 to reset.
[0030] When the rail vehicle 1 continues to go straight along the straight track, at this time the hydraulic cylinder on the left drives the limiting wheel 14 to move down, the limiting wheel 14 is in close contact with the outer side of the first parallel track 5, at this time the left driving wheel 4 is limited on the first parallel track 5 through the flanges 42 and the limiting wheels 14, so that the left driving wheel 4 continues to drive along the first parallel track 5, and the rail vehicle 1 and the right driving wheel 4 continue to go straight, when the right driving wheel 4 transitions from the first straight track section 61 to the second straight track section 62, the flange 42 of the right driving wheel 4 falls on the first pad 11, and the main wheel body 41 of the right driving wheel 4 is suspended, when the right driving wheel 4 transitions from the second straight track section 62 to the third straight track section 63, the flange 42 of the right driving wheel 4 falls on the straight pad 122, and the main wheel body 41 is empty, the first pad 11 and the straight pad 122 are arranged to avoid the suspension of the right driving wheel 4, so that the rail vehicle 1 passes through the first gap 9 and the second gap 10 smoothly, when the rail vehicle 1 completes the straight selection and passes through the second gap 10, the limiting wheel 14 driven by the hydraulic cylinder on the left is reset;
