Working principle of the present utility model is:
Neutral gear: Effector is positioned at neutral position, forward gears clamping strap 27, reverse gear clamping strap 34 unclamps, power is by fluid torque converter 1, driving shaft 10, first epicyclic gear 20 of planetary drive transmission 2, first planetary pinion 21, stir first sun gear 23 (counter-rotating), secondary sun wheel 31, second planetary pinion 29 and axle 30, second planetary carrier 32 and the 3rd sun gear 38, the third line star gear 37, the third line star gear 37, stir epicyclic gear 33 (counter-rotating), identical with second planetary pinion, 29 sense of rotation, power does not transmit in inside idle running circulation, as shown in Figure 3.
Reverse gear: gear is when reverse gear, the epicyclic gear 33 of reverse gear clamping strap 34 locking front and back crosspiece transducers 3 and braking thigh, forward gears clamping strap 27 unclamps, power is by fluid torque converter 1, driving shaft 10, planetary drive transmission 2 (oppositely), secondary sun wheel 31, second planetary pinion 29 and axle 30, second planetary carrier 32 and the 3rd sun gear 38, the third line star gear 37 and axle 59, the pump impeller 44 of the third line gear rack 39 and variable-speed shaft 11, the first fluid coupling 9, the 4th sun gear 49, fourth line star gear 47 and axle 48, fourth line gear rack 50 and the 5th epicyclic gear 51, fifth line star gear 54 and axle 53, fifth line gear rack 52, the pump impeller 58 of second fluid coupling 9, connection gear 8 outputs.Because planetary drive transmission 2 back transfer, the 3 forward transmission of front and back crosspiece transducer are so outputting power is for falling speed; Velocity ratio is:
Forward gears: forward gears clamping strap 27 locking forward gearss braking thigh 28, reverse gear clamping strap 34 unclamps, second planetary pinion 29 rotation on axle 30, stir second and third epicyclic gear 33 counter-rotatings simultaneously, drive the third line star gear 37 and axle 59 again, the third line gear rack 39 and variable-speed shaft 11 are around the double rotation of the 3rd sun gear 38 revolution.Transfer route is identical with reverse gear later on, because planetary drive transmission 2 is a back transfer, first epicyclic gear 20 of front and back crosspiece transducer 3 also is a back transfer, so the power of output is direction of advance,
At a high speed: when fifth line gear rack 52 rotating speeds increase, second fluid coupling 9 beginning transferring power, closed the 5th sun gear 55 and fifth line gear rack 52, planetary drive transmission 2 unitary rotation, velocity ratio is 1, because i
