Exported by output shaft 800；
Two gear drive paths, torque converter assemblage 100 power inputted, by power shaft 120, bidirectional clutch assembly 600 in fact
Existing cylindrical driving gear 630 and cylindrical driven gear 510 engaged transmission, then make two gears driven by the two gear clutches 500 that advance
Gear 520 and output gear 810 engaged transmission, exported by output shaft 800；
Retreat gear drive path, torque converter assemblage 100 power inputted, by power shaft 120, bidirectional clutch assembly 600
Realize retreating gear gear 620 and output gear 810 engaged transmission, output shaft 800 export.
The specific works principle of the present invention is described as follows:
The power of electromotor transmits power by torque converter assemblage 100, active force part under the effect of torque converter assemblage 100,
It is delivered on bidirectional clutch assembly 600 by power shaft 120.
Seeing Fig. 2 and Fig. 3, the first cylindrical support member 670 is by being fixedly welded on bidirectional clutch axle 690, and cylindrical props up
Being provided with first piston assembly the 660, first friction plate the 650, first partition 640 in support member 670, first piston assembly 660 is installed
In the inner chamber of the first cylindrical support member 670, first partition the 640, first friction plate 650 is installed the most successively, first every
The square dop of sheet 640 cylindrical is just embedded in the draw-in groove of the first cylindrical support member 670, and interior on the first friction plate 650
Spline is then matched by spline with the external splines of shift gear.After hydraulic oil is filled into the inner chamber of first piston assembly 660,
Hydraulic oil can overcome the spring force of the first return spring 680, promotes first piston assembly 660 to be rubbed with first by first partition 640
Pad 650 compresses.The bidirectional clutch axle 690 rotated drives the first cylindrical support member 670 to rotate, thus drives the first partition
640 rotate in the lump, and the first partition 640 is to compress with the first friction plate 650, by the friction pair between them, first every
Sheet 640 delivers torque to the first friction plate 650.Internal spline on first friction plate 650 can drive a gear driving gear 610 or
Retreat gear gear 620.
See Fig. 5, when hydraulic oil is poured in bidirectional clutch assembly 600 left hand piston chamber, it will drive a gear driving tooth
Wheel 610 rotation；One gear driving gear 610 is meshed with the first excessive gear 710, sees Fig. 5, and power passes through First Transition gear
710 pass to the second transition gear 720, and the second transition gear 720 is meshed with output gear 810, and power is by the second transition tooth
Wheel 720 passes to output gear 810, completes the output of moment of torsion, it is achieved the forward gear function of car load.
See Fig. 7, when hydraulic oil is poured in bidirectional clutch assembly 600 right hand piston chamber, it will drive and retreat gear gear
620 rotate.Retreating gear gear 620 to be directly meshed with output gear 810, power is delivered to output gear by retreating gear gear 620
Wheel 810, it is achieved vehicle rollback gear function.
See Fig. 2, Fig. 4 and Fig. 6, when the chamber, left and right two of bidirectional clutch assembly 600 is not filled with hydraulic oil, electromotor
Power can pass to advance outside two gear clutch assemblies 500 by the cylindrical driving gear 630 on bidirectional clutch assembly 600
Circle driven gear 510, when the plunger shaft of two gear clutch assemblies 500 of advancing is filled with hydraulic oil, power can be driven through cylindrical
Gear the 510, second partition the 540, second friction plate 550 passes to two gear driven gears 520, two gear driven gears 520 and output
Gear 810 is meshed, and power is transferred to output gear 810, it is achieved that the function of advance two gear of vehicle.
See Fig. 7, when, after hydraulic oil off-load, the second piston assembly 560 of two gear clutch assemblies 500 of advancing is at second time
Resetting under the spring-force driven dual of position spring 580, the second partition 540 and the second friction plate 550 release and compress, and release moment of torsion transmission.
When bidirectional clutch assembly 600, two gear clutch assemblies 500 of advancing the most do not have hydraulic oil to be filled with, variator is in neutral
Position, does not has power to transmit.
Seeing Fig. 8, the power of electromotor transmits power by torque converter assemblage 100, and sub-fraction power passes through torque-converters
Gear 130, imparts power to idle pulley 920, and first is meshed with idle pulley 920 for oilgear 910, and first carries for oilgear 910
Dynamic fuel feeding output shaft 930 works, it is achieved two PTO power outputs, it is achieved band working barrel and lubricating pump simultaneously.
