Degree rotation is slided；
S2. single-chip microcomputer 1 sends time delay 1 second after command M, that is, send a command N leads to it to the second single flow electromagnet 7
Electricity, absorption selector fork 10 pulls sleeve 9 to move axially, and the external splines and small driven gear 13 for making the one end of sleeve 9 are disengaged from,
With big driven gear 6 into engaging, power is changed to one grade to the external splines of the other end of sleeve 9 from two grades；
S3. single-chip microcomputer 1 sends time delay 1 second after command N, that is, sending the instruction single flow of P to first electromagnet 8 makes it break
Electricity, no longer adsorbs big drive gear 14, and big drive gear 14 is acted on and return due to the elastic force of the first return spring, drive it is small from
Moving gear 13 dallies, and rear drive sprocket 11 drives operating by big driven gear 6, and dolly is with one grade of climbing.
In the present embodiment, when carriage descending, its speed can be increasingly faster, when grating wheel speed sensors 2 sense axle speed
Increase to the first setting value（The complete velocity amplitude in ramp can be slided with the speed by determining dolly after measuring and calculating）When, now
The step of electrically-controlled component controls power transfer assembly gear shift be：
S4. grating wheel speed sensors 2 send an electric signal B to single-chip microcomputer 1, and single-chip microcomputer 1 sends a command M to first again
Single flow electromagnet 8 makes it be powered, and adsorbing big drive gear 14 makes it stop operating, roll 17 and rear drive sprocket semiaxis 4
Static, unilateral bearing 12 is in non-lockup state, and rear drive sprocket 11 is rotated with the first gear speed before braking and slided；
S5. single-chip microcomputer 1 sends time delay 1 second after command M, that is, send one and instruct the single flow of Q to second electromagnet 7 it is broken
Electricity, no longer adsorbs selector fork 10, and sleeve 9 axially moves back to position under the elastic force effect of the second return spring 5, outside its one end
Spline is disengaged from big driven gear 6, and the external splines of the other end is engaged with small driven gear 13, and dolly power is changed to from one grade
Two grades, rear drive sprocket 11 continues coast in the case where roll 17 and rear drive sprocket semiaxis 4 are still in inactive state；
When S6. after carriage descending to level road, speed is more and more slower, when raster velocity sensor sensing to axle speed is reduced to
Two setting values（The velocity amplitude that i.e. dolly will not stop）When, that is, an electric signal C to single-chip microcomputer 1 is sent, single-chip microcomputer 1 sends one again
The instruction single flow of P to first electromagnet 8 powers off it, no longer adsorbs big drive gear 14, and big drive gear 14 is in the first return
The lower return of elastic force effect of spring, roll 17 and rear drive sprocket semiaxis 4 start running, and dolly returns to two grades of travelings.
The utility model adds Single-chip Controlling formula using infrared tube intelligent-induction, can independently sense be arranged on completely
The ramp of optional position and gear shift is completed on racing track, be avoided that different ramp positions realize the resistance of climb and fall function to dolly
Hinder, smoothly realize climb and fall function；Single flow electromagnet is used to adsorb drive gear super plus unilateral bearing with brake system
The mode for more travelling, can avoid dolly from first stopping the phenomenon restarting in gearshift procedure, and can be prevented effectively under the phenomenon causes
Counterweight gravitational potential loss of energy；And can make traveling energy of the dolly during descending be only derived from itself kinetic energy and
Gravitional force, with little need for using the gravitional force of counterweight, and fully relies on its initial kinetic energy and its weight in Po Ding positions
Power potential energy can be achieved with descending, can save the gravitional force of counterweight, and the energy under saving can make the farther of dolly traveling.
