Operation principle：Advance one grade：Total input shaft 4 is driven to rotate by the turbine wheel shaft 201 of fluid torque-converter 200, so as to
So that the 3rd travelling gear 9 rotates, the 3rd travelling gear 9 drives the 4th clutch drive gear 15 to rotate, and now the 4th pressure
Block 27 compresses corresponding active friction plate 104 and driven friction disk 105, so that second clutch axle 2 rotates so that the 5th
Travelling gear 13 rotates, and the 5th travelling gear 13 drives the 7th travelling gear 17 to rotate, so as to realize that propons output shaft 5 rotates
(now, the first briquetting 24, the second briquetting 25, the 3rd briquetting 26 and the 5th briquetting 28 be not by corresponding active friction plate 104
It is compacted with driven friction disk 105 to realize transmission)；And when the 5th in de- bridge axle 3 presses fast 28 by corresponding active friction plate 104
When being compacted with driven friction disk 105, just de- axle gear 18 is driven to rotate by the 6th travelling gear 16 so that de- bridge axle 3 rotates,
And de- bridge axle 3 drives outrigger shaft 19 to rotate, outrigger shaft 19 drives the 9th travelling gear 21 to rotate by the 8th travelling gear 20, from
And back axle output shaft 6 is rotated.
Advance two gears：Total input shaft 4 is driven to rotate by the turbine wheel shaft 201 for crossing fluid torque-converter 200 so that the second transmission
Gear 8 is driven, and has driven the 3rd clutch drive gear 14 to be driven, and then, is compressed corresponding active by the 3rd briquetting 26 and is rubbed
Pad 104 and driven friction disk 105 so that second clutch axle 2 rotates so that the 5th travelling gear 13 rotates, the 5th transmission
Gear 13 drives the 7th travelling gear 17 to rotate, so as to realize that propons output shaft 5 rotates (now, the first briquetting 24, the second briquetting
25th, corresponding active friction plate 104 and driven friction disk 105 are not compacted to realize by the 4th briquetting 27 and the 5th briquetting 28
Transmission)；And when corresponding active friction plate 104 and driven friction disk 105 are compacted by the 5th pressure fast 28 in de- bridge axle 3, just
De- axle gear 18 is driven to rotate by the 6th travelling gear 16 so that de- bridge axle 3 rotates, and de- bridge axle 3 drives 19 turns of outrigger shaft
Dynamic, outrigger shaft 19 drives the 9th travelling gear 21 to rotate by the 8th travelling gear 20, so that back axle output shaft 6 rotates.
Ahead three is kept off：Total input shaft 4 is driven to rotate by the turbine wheel shaft 201 for crossing fluid torque-converter 200 so that the first transmission
Gear 7 is driven, and has driven first clutch travelling gear 11 to be driven, and then, is compressed corresponding active by the first briquetting 24 and is rubbed
Pad 104 and driven friction disk 105 so that first clutch axle 1 rotates so that the 4th travelling gear 10 rotates, the 4th transmission
Gear 10 drives the 7th travelling gear 17 to rotate, so as to realize that propons output shaft 5 rotates (now, the second briquetting 25, the 3rd briquetting
26th, corresponding active friction plate 104 and driven friction disk 105 are not compacted to realize by the 4th briquetting 27 and the 5th briquetting 28
Transmission)；And when corresponding active friction plate 104 and driven friction disk 105 are compacted by the 5th pressure fast 28 in de- bridge axle 3, just
De- axle gear 18 is driven to rotate by the 6th travelling gear 16 so that de- bridge axle 3 rotates, and de- bridge axle 3 drives 19 turns of outrigger shaft
Dynamic, outrigger shaft 19 drives the 9th travelling gear 21 to rotate by the 8th travelling gear 20, so that back axle output shaft 6 rotates.
Retreating gear：Total input shaft 4 is driven to rotate by the turbine wheel shaft 201 for crossing fluid torque-converter 200 so that the 3rd driving cog
The transmission of wheel 9, the 3rd travelling gear 9 drive idle pulley 23 to rotate, and idle pulley 23, which rotates, has driven second clutch travelling gear 12 to be driven,
Then, corresponding active friction plate 104 and driven friction disk 105 are compressed by the second briquetting 25 so that 1 turn of first clutch axle
It is dynamic so that the 4th travelling gear 10 rotates, and the 4th travelling gear 10 drives the 7th travelling gear 17 to rotate, so as to realize that propons is defeated
Shaft 5 rotates that (now, the second briquetting 25, the 3rd briquetting 26, the 4th briquetting 27 and the 5th briquetting 28 be not by corresponding active
Friction plate 104 and the compacting of driven friction disk 105 are driven to realize)；And when the 5th in de- bridge axle 3 presses fast 28 by corresponding active
When friction plate 104 and driven friction disk 105 are compacted, just de- axle gear 18 is driven to rotate by the 6th travelling gear 16 so that de-
Bridge axle 3 rotates, and de- bridge axle 3 drives outrigger shaft 19 to rotate, and outrigger shaft 19 drives the 9th driving cog by the 8th travelling gear 20
Wheel 21 rotates, so that back axle output shaft 6 rotates.
The output end of propons output shaft 5 and back axle output shaft 6 is connected with Hooks coupling universal coupling.
