Several roller bearings 11 also are provided between axis 9, avoid producing between transmission input shaft 2, main transformer speed driving gear shaft 6 and housing 1
Raw larger friction, the energy of friction loss when reducing transmission, and then improve transmission efficiency.
Specific implementation process：When needing to put into forward gear, the drive in the wrong direction retrograde synchronizer assembly 4 of the cooperation of shift fork 41 and main transformer speed
Sliding tooth 42 on five gear driving gears 5 engages, and transmission input shaft 2 is rotated through the driving master of synchronizer assembly 4 that drives in the wrong direction at this time
Speed change five is kept off driving gear 5 and is rotated, and main transformer speed five keeps off driving gear 5 and main transformer speed driving gear shaft 6 is driven to rotate, at this time main transformer speed
The steering of driving gear shaft 6 is identical with the steering of transmission input shaft 2；When needs are linked into and reverse gear, the shift fork 41 that drives in the wrong direction coordinates inverse
Row synchronizer assembly 4 is engaged with the sliding tooth 42 on retrograde driving gear 3, and transmission input shaft 2 rotates same by driving in the wrong direction at this time
Step device assembly 4 drives the driving gear 3 that drives in the wrong direction to rotate, and the driving gear 3 that drives in the wrong direction is rotated makes the device duplicate gear that drives in the wrong direction by the transmission of idle pulley 7
8 rotate, and then transmission shaft 9 rotates, the steering of transmission shaft 9 at this time turned to transmission input shaft 2 it is identical, inter-axle shaft 9 it is another
The retrograde device duplicate gear 8 of side drives main transformer speed five to keep off driving gear 5 and rotates, and then main transformer speed driving gear shaft 6 rotates, at this time
6 rotation direction of main transformer speed driving gear shaft and the rotation direction of transmission input shaft 2 are on the contrary, the process that realization is reversed gear.
In conclusion the utility model has by the way that thrust bearing 12 and baffle ring 13 is set to limit the synchronizer assembly 4 that drives in the wrong direction
Axial movement, avoid driving in the wrong direction synchronizer assembly 4 and retrograde driving gear 3, main transformer speed driving gear shaft 6 abuts locking makes to put into gear
Failure；Effect is driven by the way that needle bearing 61 and roller bearing 11 is set to reduce abrasion, while is promoted to rotate smoothness and then improve
Rate；By setting gear semicircle baffle ring 51 and snap ring 52 that five gear driving gear 5 of main transformer speed is avoided to move axially, ensure the shift fork that drives in the wrong direction
41 smoothly put into forward gear and main transformer speed five are avoided to keep off the advantages of driving gear 5 abuts locking with retrograde synchronizer assembly 4.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model be subject to Patent Law.
