Accompanying drawing explanation
Content expressed by width accompanying drawing each to this specification and the labelling in figure are briefly described below:
Fig. 1 is gearbox designs schematic diagram of the present invention.
In figure: 1. input driving gear, middle driven gear, 3. first clutch, 4. output gear, 5. deceleration are actively Gear, middle driving gear, 7. input driven gear, 8. second clutch, 9. reduction driven gear, 10. differential mechanism, 11. Power shaft, 12. output shafts.
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.
Being fixed with parking wheel on output shaft 12, parking wheel and deceleration driving gear lay respectively at the both ends of output shaft.In Between driven gear between input driving gear and output gear, middle driving gear be positioned at deceleration driving gear and input from Between moving gear.Compact conformation, it is simple to arrange.
First clutch 3 is identical with second clutch 8 structure, and it includes piston, thrust bearing and friction plate group, described Piston is located on gear box casing, and the head of piston is by thrust bearing and friction plate group phase separation.In clutch, plunger shaft is not Rotating, without the centrifugal force impact on pressure, beneficially Stress control, Clutch Control is more accurate.
