Front and back crosspiece gear is a planet speed change mechanism, it comprise gear ring 15, the first planetary gear 16,The second planetary gear 17, planet carrier component 18 and with the power output shaft 21 of the coaxial setting of gear shaft 19,Power output shaft 21 is rotated and connects with gear shaft 19 by bearing, and gear shaft 19 axles are provided with the gear shaft sunWheel, the first planetary gear 16, the second planetary gear 17 are installed on planet carrier component 18, the first planetGear 16 engages with gear shaft sun gear, the second planetary gear 17 respectively with the first planetary gear 16 and gear ring15 engagements, shifter collar 20 is slidably mounted on power output shaft 21 by spline or internal tooth, shifter collar20 between planet carrier component 18 and gear shaft 19, and shifter collar 20 is provided with and planet carrier component 18The internal tooth that the external tooth of engagement and the external tooth being provided with gear shaft 19 are meshed.
The transfer route of each gear of this 10+10 gear gearbox is:
One grade: shift fork is stirred one grade of synchronized 8 and made it and one grade of gear 9 combination of two axles is one grade of main transformer speed,The pass order of power is: the first axle 1 → often engage driving gear 2 → often engage driven gear 26 → jackshaft9 → mono-grades of synchronizeds of one grade of gear of one grade of gear of 27 → jackshaft, 22 → bis-axle, 8 → the second axles 12.
Second gear: shift fork is stirred two third gear synchronizeds 6 and made it and two axle intermediate gear 7 combinations, is main transformer speed twoShelves, the pass order of power is: the first axle 1 → often engage driving gear 2 → often engage driven gear 26 → inCountershaft 27 → secondary gear of intermediate shaft 23 → bis-axle intermediate gear 7 → bis-third gear synchronized 6 → the second axles 12.
Third gear: shift fork is stirred two third gear synchronizeds 6 and made it and two axle third gear 5 combinations, is main transformer speed threeShelves, the pass order of power is: the first axle 1 → often engage driving gear 2 → often engage driven gear 26 → inCountershaft 27 → third-speed gear of intermediate shaft 24 → bis-axle third gear 5 → bis-third gear synchronized 6 → the second axles 12.
Fourth gear: shift fork is stirred four Five-gear synchronizers 3 and made it and two axle fourth gear 4 combinations, is main transformer speed fourShelves, the pass order of power is: the first axle 1 → often engage driving gear 2 → often engage driven gear 26 → inCountershaft 27 → jackshaft fourth gear 25 → bis-axle fourth gear 4 → tetra-Five-gear synchronizer 3 → the second axles 12.
Five grades: shift fork is stirred four Five-gear synchronizers 3 and made it and the first axle 1 combination, for five grades of main transformer speed, movingThe pass order of power is: the first axle 1 → tetra-Five-gear synchronizer 3 → the second axles 12.
After main speed-changing mechanism enters high and low shift gear, the gear change in high and low shift gear is:
It is high-grade: driving cog cover 14 stirred by high and low shift gear district gear lever and the second axle 12 combinations are high-grade,The pass order of power is: second axle 12 → driving cog cover 14 → gear shaft 19.
It is low-grade: it is low-grade with planet carrier 13 combinations that high and low shift gear district gear lever is stirred driving cog cover 14,The pass order of power is: second axle 12 → planetary gear → planet carrier 13 → driving cog cover 14 → gear shaft19。
After high and low shift gear, enter after front and back crosspiece gear, gear change is:
Drive shift: it is neutral position that front and back crosspiece gear district shift fork stirs that shifter collar 20 mediates, and nibblesClose tooth cover 20 and move with gear shaft 19 in conjunction with being drive shift, the pass order of power is: gear shaft 19 → nibbleClose tooth cover 20 → power output shaft 21.
Backward gear: front and back crosspiece gear district shift fork is stirred shifter collar 20 and moved with planet carrier component 18 and tieClosing is backward gear, and the pass order of power is: gear shaft 19 → the first planetary gears 16, the second planetary gear17 → planet carrier component, 18 → shifter collar, 20 → power output shaft 21.
