Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the preferred embodiment of the present invention is elaborated.
See Fig. 1, the double clutch planet row type pure electric automobile variator of the present invention, including the power shaft 2 driving motor 1 to be connected with the rotor of one end with this driving motor 1, comprise gear ring 10, rear planetary gear 11, rear sun gear 12, planet axis 13, the planet row of planet carrier 14, and first clutch 3, second clutch 4, interior axle 6 and output shaft 15, described rear planetary gear 11 empty set and is meshed with rear sun gear 12 and gear ring 10 in the planet axis 13 of the planet carrier 14 of planet row simultaneously.nullAs seen from Figure 1，Present invention additionally comprises outer shaft 5、Front sun gear 7、Front planetary gear 8，Described power shaft 2、Interior axle 6 and output shaft 15 coaxial inner conductor from left to right arrange and interior axle 6 is positioned among outer shaft 5，It is left、Right half stretches out in a left side for outer shaft 5 respectively、Outside right-hand member，The rear sun gear about 12 of described front sun gear 7 and planet row arranges side by side and front sun gear 7 is fixed on outer shaft 5、Rear sun gear 12 is fixed on the right half of the right-hand member that interior axle 6 stretches out in outer shaft 5，In the planet axis 13 of the planet carrier 14 of planet row and front planetary gear 8 engages described front planetary gear 8 with front sun gear 7 with rear planetary gear about 11 empty set side by side，Described first clutch 3 and second clutch about 4 are arranged side by side and the external drum of the external drum of first clutch 3 and second clutch 4 all connects firmly with power shaft 2、The left half that the interior hub of first clutch 3 and interior axle 6 stretch out in outside the left end of outer shaft 5 is connected、The interior hub of second clutch 4 is connected with outer shaft 5，The right-hand member of the planet carrier 14 of described planet row connects firmly mutually with the left end of output shaft 15.So, arrange due to power shaft 2, interior axle 6 and output shaft 15 coaxial inner conductor from left to right and interior axle 6 is positioned among outer shaft 5.Thus, the overall radial dimension of the present invention is less, radial direction takes up room less, can not only assemble and be used in the automobile that radially assembly space is bigger, it is also possible to assembling is used in the automobile that radially assembly space is less, and adaptability is preferable.The peripheral components such as meanwhile, first clutch 3 and second clutch about 4 are arranged side by side, eliminate the one grade of driving gear and two grades of driving gears being provided with between them, the housing of two outer clutch drums just can share.Thus, it is possible to reduce cost and take up room less, arrangement is also made to be easier.Additionally, the present invention only increases outer shaft 5, front sun gear 7 and front planetary gear 8, just decrease one grade of driving gear, one grade of driven gear, two grades of driving gears, two grades of driven gears.Thus, reducing cost, overall structure is the most fairly simple.
Described first clutch 3 and second clutch 4 are multi-plate wet clutch.Thus, it is possible to utilize first clutch 3 and the bigger sliding wear thermal capacity of second clutch 4, it is ensured that the smooth gear shifting of the present invention is without impact.Meanwhile, it is capable to by first clutch 3 and second clutch 4 in combination with, it is achieved the locking of planet carrier 14, play the effect of parking parking, prevent automobile from coming down, work the most reliable.
The operation principle of the present invention is as follows；
One grade, driving motor 1 to rotate forward, the external drum of first clutch 3 and interior hub disconnect, and the external drum of second clutch 4 and interior hub combine；Power passes to front sun gear 7 by second clutch 4, and front planetary gear 8 is on the one hand around planet wheel spindle 13 rotation of planet carrier 14 together with rear planetary gear 11, and the centrage around front sun gear 7 revolves round the sun simultaneously.Then, drive the power of motor 1 to sequentially pass through power shaft 2, second clutch 4, outer shaft 5, front sun gear 7, front planetary gear 8, rear planetary gear 11, planet axis 13 and planet carrier 14, export finally by output shaft 15.Now, one grade of gear ratio is formed.One grade of power path: drive motor 1, power shaft 2, second clutch 4, outer shaft 5, front sun gear 7, front planetary gear 8, rear planetary gear 11, planet axis 13, planet carrier 14, output shaft 15.
Two grades, driving motor 1 to rotate forward, the external drum of first clutch 3 and interior hub combine, and the external drum of second clutch 4 and interior hub disconnect；Power passes to rear sun gear 12 by first clutch 3, and rear planetary gear 11 1 aspect is around planet wheel spindle 13 rotation of planet carrier 14, and the centrage around rear sun gear 12 revolves round the sun simultaneously.Then, drive the power of motor 1 to sequentially pass through power shaft 2, first clutch 3, interior axle 6, rear sun gear 12, rear planetary gear 1, planet axis 13 and planet carrier 14, export finally by output shaft 15.Now, two grades of gear ratios are formed.Two grades of power path: drive motor 1, power shaft 2, second clutch 4, outer shaft 5, front sun gear 7, front planetary gear 8, rear planetary gear 11, planet axis 13, planet carrier 14, output shaft 15.
Reverse gear, drives motor 1 to invert, and the external drum of first clutch 3 and interior hub disconnect, and the external drum of second clutch 4 and interior hub combine；Power passes to front sun gear 7 by second clutch 4, and front planetary gear 8 is on the one hand around planet wheel spindle 13 rotation of planet carrier 14 together with rear planetary gear 11, and the centrage around front sun gear 7 revolves round the sun simultaneously.Then, drive the power of motor 1 to sequentially pass through power shaft 2, second clutch 4, outer shaft 5, front sun gear 7, front planetary gear 8 and rear planetary gear 11, planet axis 13 and planet carrier 14, export finally by output shaft 15.Now, one grade of gear ratio is formed.One grade of power path: drive motor 1, power shaft 2, second clutch 4, outer shaft 5, front sun gear 7, front planetary gear 8, rear planetary gear 11, planet axis 13, planet carrier 14, output shaft 15.
Gear switch, automobile is when running for one grade, and variator automatic control unit is known vehicle running state according to related sensor, and then judged, as accelerated just to enter two grades, concrete gearshift is as follows；Vehicle is when one grade of operation reaches to change the shifting points such as two grades, and the second clutch 4 being in bonding state is gradually turned off, and the first clutch 3 being simultaneously in off-state gradually combines；Two clutch alternately switchings, until second clutch 4 is fully disconnected, first clutch 3 is completely combined, and whole gearshift terminates, and vehicle changes to two grades.Vehicle from two grades change to the process of a grade just with change to the process contrary of two grades, specific as follows；Vehicle is when two grades of operations need to change one grade, and the first clutch 3 being in bonding state is gradually turned off, and the second clutch 4 being simultaneously in off-state gradually combines；Two clutch alternately switchings, until first clutch 3 is fully disconnected, second clutch 4 is completely combined, and whole gearshift terminates, and vehicle changes to one grade.
Parking, cuts off the power supply driving motor 1, the external drum of first clutch 3 and interior hub and combines, and the external drum of second clutch 4 and interior hub combine, and planet row entirety cannot rotate.Now, planet carrier 14 can not rotate, it is achieved parking function.
In vehicle traveling process, running into special road section, the too high appearance of vehicle wheel rotational speed is counter drags, now can control clutch bonding state realize the sliding wear of external drum and interior hub to ensure safety.
The content that the present invention is not described in is prior art.
Description to the preferred embodiment of the present invention above is the illustration making the present invention.Those skilled in the art can carry out various amendment, supplement or use similar mode to substitute described preferred implementation, but without departing from the spirit of the present invention or surmount scope defined in appended claims.
