Description
Technical field
The present invention relates to a kind of double-clutch automatic gearboxes, more particularly to a kind of electronic automobile-used 3 gear double clutch automatic speed changing
Device.
Background technology
Pure electric automobile has many advantages, such as small noise, zero-emission, easily operated and safeguard, is passed since effect on environment is opposite
Uniting, automobile is smaller, and foreground is had an optimistic view of extensively.
Since the driving motor of pure electric automobile has good governor control characteristics, pure electric vehicle power in industry
Transmission system the more uses single shift transmission or two-gear transmission, still, in the lower electricity of larger and rotating speed for torque demand
When motor-car, for example, using single shift transmission, will be unable to meet simultaneously in the passenger car or load-carrying vehicle of 8t to 14t for load-carrying
Load-carrying ability and maximum speed, currently, climbable gradient has occurred in country's mainstream 8t-14t electric bus (or electronic logistic car)
Insufficient problem (climbable gradient<20%, usually<15%).Using two-gear transmission structure, then a gear speed ratio is too big, so that
The maximum speed of one gear state is too low (usually<30Kph), and if lasting climbing, often smaller is (usual for speed<15Kph)；And
Two gears are promoted to meet maximum speed, often use overgear (i.e. monodentate wheel set speed ratio<1).In this way so that adjacent gear speed difference
Excessive, if needing certain climbing when encountering normally travel region (speed 20-60kph), there are two to keep off unable to do what one wishes a, gear
The technical issues of speed is not achieved, and two gear torques are not achieved.
Patent document CN104763798A discloses a kind of gear of pure electric vehicle bus three double clutch automatic speed changing case, referring to figure
5, which is：Including motor connection axle 1, double clutch 2, the first input shaft 3, the second input shaft 4, first gear

Device transmission be connected, output end is provided with synchronizer 6, by synchronizer respectively with it is defeated on first gear driving gear 5 and output shaft 8
Go out gear 9 to match, wherein first gear driving gear 5 is set on the first input shaft 3, in synchronizer 6 and first gear driving tooth
When wheel 5 combines, first gear driving gear 5 will follow the first input shaft 3 to rotate；Output gear on synchronizer 6 and output shaft 8
When 9 combination, output shaft 8 will follow directly after the first input shaft 3 and rotate, and first gear driving gear 5 does not follow；And synchronizer 6
Specific location is determined by motor speed, be may respectively be the combination of first gear driving gear 5, centre position and output gear and is combined, the
Two gear driven gears 12, first gear driven gear 13 and final gear 14 are successively set on countershaft 11, and respectively with second
Gear gear 7, first gear driving gear 5 and output gear 9 are meshed.It follows that the program includes the first input shaft, the
Two input shafts, output shaft and countershaft, structure is complex, and process costs are higher, in addition, in the program, the first input shaft is made
It is penetrated in the second input shaft for punching axle, and uses odd even double clutch, cause the length of punching axle longer and relatively thin, it is difficult to negative
Lotus large torque increases the rigidity requirement and difficulty of processing of whole axis, can not ensure technological feasibility and commercial viability.
