Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Explanation.
As it is shown in figure 1, this automatic gear-box, subtract gear, differential mechanism 10, clutch including power shaft 11, output shaft 12, master
And gear box control unit, wherein, clutch includes first clutch 3 and second clutch 8, and output shaft 12 is positioned at power shaft
Between 11 and the rotating shaft of differential mechanism 10, the most parallel to each other between the rotating shaft of power shaft 11 and output shaft 12 and differential mechanism 10 set
Put, subtract gear by master between differential mechanism with output shaft and be connected, simple in construction, it is simple to arrange.
It is fixed with input driving gear 1 on power shaft 11, output shaft 12 is set with and inputs what driving gear 1 was meshed
Input driven gear 7, power shaft 11 is set with middle driven gear 2 and output gear 4, middle driven gear 2 and output gear
Being provided with, between wheel 4, the first clutch 3 that both control combines or disconnects, first clutch 3 is one grade of clutch；On output shaft 12
Being set with the middle driving gear 6 being meshed with middle driven gear 2, middle driving gear 6 is connected with input driven gear 7,
Being provided with, between input driven gear 7 and output shaft 12, the second clutch 8 that control combines or disconnects, second clutch 8 is
Two grades of clutches.
Master subtracts gear and includes deceleration driving gear 5 and reduction driven gear 9, and deceleration driving gear 5 is fixed on output shaft 12
On, differential mechanism 10 is provided with the reduction driven gear 9 being meshed with deceleration driving gear.
