As shown in fig. 4, to achieve the above object, the present invention provides another continuously variable transmission system with uninterrupted dual motor power shifting, comprising: the output shaft 2 of the engine is simultaneously connected with the flywheel 1, the driving gear 3 of the Z1 and the driving disc of the main clutch 5; the gearbox input shaft 6 is connected with a driven disc of the main clutch 5; the Zn driven gear 4 is meshed with the Z1 driving gear 3 while being connected with the input shaft of the generator 7 or through a speed increasing and decreasing transmission gear (not shown); zd1 drive gear 9 is coupled to the output shaft of motor 8; the Zd2 driven gear 10 is meshed with the Zd1 driving gear 9 and is simultaneously coupled with the driving ring 30 of the overrunning clutch; the driving gear 17 of the high-speed Zd3 is connected with the driven ring 31 of the overrunning clutch through the driving disk input shaft 14; the speed change output shaft 19 is simultaneously coupled with the gearbox output shaft 20 and the high-speed Zd4 driven gear 18; wherein the gearbox output shaft 20 is coupled to the gearbox input shaft 6 via a gearbox gearset and the high speed Zd3 drive gear 17 is meshed with the high speed Zd4 driven gear 18.
In some embodiments, a continuously variable transmission system for uninterrupted dual-motor power shifting includes a dual-motor power shifting mode, wherein the shifting process comprises: during gear shifting, the main clutch 5 is gradually separated to cut off the power of the input shaft 6 of the gearbox, and at the moment, the motor 8 drives the driving gear 9 of the Zd1, the driven gear 10 of the Zd2 and the input shaft 14 of the driving disc to enter a gear shifting rotating speed tracking mode; when the rotating speed of the driving ring 30 of the overrunning clutch exceeds the rotating speed of the driven ring 31 of the overrunning clutch, the driving ring 30 is rapidly combined with the driven ring 31, and meanwhile, the motor 8 outputs uninterrupted power during gear shifting to the speed change output shaft 19 through the Zd1 driving gear 9, the Zd2 driven gear 10, the driving ring 30, the driven ring 31, the driving disc input shaft 14, the high-speed Zd3 driving gear 17 and the high-speed Zd4 driven gear 18; after gear shifting is completed, the engine drives the driving disc of the main clutch 5 to regulate speed, when the rotating speed of the driving disc of the main clutch 5 is matched with the rotating speed of the input shaft 6 of the gearbox, the main clutch 5 is combined, meanwhile, the motor 8 unloads and decelerates, the driving coil 30 and the driven coil 31 of the overrunning clutch are separated, and the gear shifting process is completed.
The main difference between the embodiment of fig. 4 and the embodiment of fig. 1-2 is that fig. 4 employs an overrunning clutch instead of the double-sided clutch or double-sided synchronizer 23 described above, and a single power path scheme. When the driving gear 9 of the Zd1 drives the driving ring 30 to rotate, the power of the motor 8 can be transmitted to the speed change output shaft 19 through the driving gear 9 of the Zd1, the driven gear 10 of the Zd2, the input shaft 14 of the driving disc, the driving gear 17 of the high-speed Zd3 and the driven gear 18 of the high-speed Zd 4; when the motor 8 is not rotating, the Zd2 driven gear 10 cannot be rotated by the positive and negative rotation of the driving disk input shaft 14.
The embodiment of fig. 4 also provides another installation method of the bi-directional overrunning clutch, please refer to the positions shown in (30), (31) of fig. 4. When the overrunning clutch driving ring 30 is connected with the high-speed Zd4 driven gear 18, the driven ring is connected with the speed change output shaft 19, and the high-speed Zd4 driven gear 18 drives the driving ring 30 to rotate, the power of the motor 8 can be transmitted to the speed change output shaft 19 through a Zd1 driving gear 9, a Zd2 driven gear 10, a driving disc input shaft 14, a high-speed Zd3 driving gear 17, a high-speed Zd4 driven gear 18, the driving ring 30 and a driven ring 31; when the motor 8 is not rotating, the high speed Zd4 driven gear 18 cannot be rotated by the normal and reverse rotation of the change speed output shaft 19.
The overrunning clutch scheme is suitable for power gear shifting systems of middle and small horsepower automobiles and tractors, and when the vehicles are not shifted, the motor 8 can not rotate along with the overrunning clutch; the idle power loss of the motor 8 of 3-5 kilowatts can be saved in different vehicle applications.
The operating principle of the overrunning clutch of the embodiment of fig. 4 is as follows: firstly, the driving part and the driven part are separated, and in the one-way overrunning clutch, as long as the driven part is faster than the driving part, the two parts are separated and do not work any more. The bidirectional overrunning clutch has the same principle, and as long as the driven part in two directions is faster than the driving part, the driven part and the driving part are separated. However, if the driving member is faster than the driven member, the driving member rotates at the same speed with the driven member and transmits power. The bidirectional overrunning clutch has the same reason, and as long as the driving in two directions is faster than the driven, the driving is driven to rotate.
In this embodiment: the Zd2 driven gear 10 is a driving part relative to the driving disk input shaft 14, the driving disk input shaft 14 is a driven part, when the motor does not rotate, the Zd2 driven gear 10 does not rotate the driving disk input shaft 14, and the rotation directions are both faster than those of the Zd2 driven gear 10, so the clutch is disengaged and does not transmit power. When the motor 8 rotates with the Zd2 driven gear 10, both directions are possible, and as long as the rotational speed exceeds the drive disk input shaft 14, the motor 8 rotates with the drive disk input shaft 14 and transmits power to the drive disk input shaft 14. The scheme solves the following problems:
1. when the gear is not shifted and the CVT is not needed, the motor 8 does not rotate, so that the idle consumption of the motor 8 is reduced, mainly the electromagnetic eddy current loss is reduced, 3-5KW can be saved generally, and the electric vehicle is particularly suitable for medium and small power vehicles.
2. When the reverse gear is performed, the motor 8 rotates reversely, the Zd2 driven gear 10 is a driving piece, and the driving disc input shaft 14 is driven to rotate, so that the reverse gear is realized.
3. During gear shifting, the motor 8 positively rotates to drive the driving disc input shaft 14 to positively rotate to transmit power gear shifting power, so that the main clutch 5 can be loosened without power interruption.
In a word, the positive and negative rotation of the driving disk input shaft 14 or the variable speed output shaft 19 which is used as a driven shaft does not influence the non-rotation of the motor 8; as long as the motor 8 rotates and has a higher rotation speed than the driving disk input shaft 14, or the variable speed output shaft 19 (second aspect), the motor 8 drives the driven shaft to rotate. As shown in fig. 5, in the schemes of fig. 1 to 4, the electromechanical power conversion system shown in fig. 5 needs to be configured to complete all the functions thereof.
