Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The power drive system 100 according to the embodiment of the present invention will be described in detail with reference to fig. 1 to 4, and the power drive system 100 is suitable for use in a vehicle such as a hybrid vehicle and serves as a power system of the vehicle to provide sufficient power and electric energy for normal running of the vehicle.
The power driving system 100 according to the embodiment of the present invention mainly includes two major parts, one of which may be a power source, which may be the engine 4, the motor generator, etc., and the other may be a transmission (including multiple input shafts, multiple output shafts, a gear pair, etc.), which is used to realize a speed change function for outputting power from the power source, and meet a vehicle running requirement or a charging requirement, etc.
For example, in some embodiments, as shown in fig. 1-4, the power-drive system 100 may include, but is not limited to, the engine 4, the first motor generator 51, and a transmission.
As shown in connection with fig. 1, in some embodiments, the transmission basically includes a plurality of input shafts (e.g., first input shaft 11, second input shaft 12), a plurality of output shafts (e.g., first output shaft 21, second output shaft 22), a motor power shaft 8 and associated gears and shifting elements (e.g., synchronizers) on each shaft.
The engine 4 is configured to selectively engage at least one of the plurality of input shafts when power is transmitted between the engine 4 and the input shafts. In other words, for example, when the engine 4 transmits power to the input shafts, the engine 4 can be selectively engaged with one of the plurality of input shafts to transmit power, or the engine 4 can also be selectively engaged with two or more of the plurality of input shafts at the same time to transmit power.
For example, in the example of fig. 1-4, the plurality of input shafts may include two input shafts, a first input shaft 11 and a second input shaft 12, and the engine 4 may be selectively engageable with one of the first input shaft 11 and the second input shaft 12 to transmit power. Alternatively, in particular, the engine 4 can also be simultaneously engaged with the first input shaft 11 and the second input shaft 12 to transmit power. Of course, it should be understood that the engine 4 may also be disconnected from both the first input shaft 11 and the second input shaft 12.
It will be apparent to those skilled in the art that the engagement state of the engine 4 and the input shaft is related to specific operating conditions of the power drive system 100, which will be described in detail below in connection with specific embodiments and will not be described in detail herein.
The input shaft and the output shaft can be transmitted through a gear pair. For example, each input shaft is provided with a gear driving gear, each output shaft is provided with a gear driven gear, and the gear driven gears are correspondingly meshed with the gear driving gears, so that a plurality of pairs of gear pairs with different speed ratios are formed.
In some embodiments of the present invention, power-driven system 100 may have seven forward-gear pairs, i.e., a first-gear pair, a second-gear pair, a third-gear pair, a fourth-gear pair, a fifth-gear pair, a sixth-gear pair, and a seventh-gear pair, and power-driven system 100 may also have one reverse-gear pair.
As shown in fig. 1 to 4, the reverse shaft 3 is sleeved with a reverse shaft first gear 31 capable of engaging with the reverse shaft 3, in other words, transmission can be performed between the reverse shaft 3 and the reverse shaft first gear 31, as shown in fig. 1 to 4, the reverse shaft 3 can be further provided with a reverse shaft first synchronizer 3c, and the reverse shaft first synchronizer 3c is used for engaging with the reverse shaft 3 and the reverse shaft first gear 31. When the first synchronizer 3c is used to engage the reverse shaft 3 and the first gear 31, the reverse shaft 3 and the first gear 31 are in transmission, and the reverse output gear 39 is linked with the reverse shaft 3, as shown in fig. 1 to 4, a second gear 32 may be fixedly disposed on the reverse shaft 3, and the second gear 32 is engaged with the reverse output gear 39. The reverse output gear 39 may be fixed to one of the output shafts. As shown in fig. 1 to 4, the reverse output gear 39 is fixed to the second output shaft 22, so that the reverse output gear 39 can be arranged reasonably, and the volume of the power drive system 100 can be further reduced.
It should be noted that the above-mentioned "linkage" may be understood as a linkage movement of a plurality of members (for example, two members), and in the case of linkage of two members, when one member moves, the other member also moves.
For example, in some embodiments of the present invention, a gear in communication with a shaft may be understood such that when the gear rotates, the shaft in communication therewith will also rotate, or when the shaft rotates, the gear in communication therewith will also rotate.
As another example, a shaft is coupled to a shaft is understood to mean that when one of the shafts rotates, the other shaft coupled thereto will also rotate.
As another example, gears may be understood to be geared with one gear so that when one gear rotates, the other gear that is geared with it will also rotate.
In the following description of the present invention, the term "linkage" is to be understood unless otherwise specified.
The first reverse shaft gear 31 is engaged with one of the gear drive gears, for example, as shown in fig. 1, the first reverse shaft gear 31 is engaged with the first gear drive gear 1a, so that the first reverse shaft gear 31 and the first gear drive gear 1a together form a reverse gear pair, and power can be transmitted between the reverse shaft 3 and the input shaft.
The first motor generator 51 is linked with the motor power shaft 8, a transmission gear is arranged between the first motor generator 51 and the motor power shaft 8, a first motor gear 84 can be arranged on the motor power shaft 8, a first transmission gear 511 is fixedly arranged on the first motor generator 51, and the first transmission gear 511 is meshed with the first motor gear 84, so that the first motor generator 51 is linked with the motor power shaft 8.
A motor power shaft first gear 81 and a motor power shaft second gear 82 are sleeved on the motor power shaft 8, each of the motor power shaft first gear 81 and the motor power shaft second gear 82 is arranged to be capable of being connected with the motor power shaft 8, a synchronizer for synchronizing the motor power shaft first gear 81 and the synchronizer for synchronizing the motor power shaft second gear 82 are arranged on the motor power shaft 8, preferably, as shown in fig. 1 and fig. 2, a motor power shaft synchronizer 8c is arranged on the motor power shaft 8, and the motor power shaft synchronizer 8c is arranged between the motor power shaft first gear 81 and the motor power shaft second gear 82, so that the parts of the power driving system 100 can be reduced, and the axial length of the power driving system 100 can be reduced.
The first motor power shaft gear 81 is linked with one of the driven gears, as shown in fig. 1 and 2, the first motor power shaft gear 81 is in transmission with the fifth-gear driven gear 5b, and as shown in fig. 3 and 4, the second motor power shaft gear 82 is in transmission with the sixth-gear driven gear 6 b. Specifically, an intermediate idle gear 83 is further disposed between the first gear 81 of the motor power shaft and the corresponding gear driven gear, and the intermediate idle gear 83 is freely sleeved on the second output shaft. As shown in fig. 1 and 2, the intermediate idle gear 83 is engaged between the motor power shaft first gear 81 and the fifth-speed driven gear 5b, and as shown in fig. 3 and 4, the intermediate idle gear 83 is engaged between the motor power shaft second gear 82 and the sixth-speed driven gear 6 b.
The motor power shaft second gear 82 is linked with the reverse gear shaft 3, specifically, as shown in fig. 1, the reverse gear shaft 3 is further fixedly provided with a reverse gear shaft second gear 32, and the reverse gear shaft second gear 32 is respectively engaged with the reverse gear output gear 39 and the motor power shaft second gear 82. In other words, the motor power shaft second gear 82 and the reverse output gear 39 are linked, so that the first motor generator 51 drives the vehicle in motion when the first motor generator 51 is used as a motor and the motor power shaft synchronizer 8c is used to synchronize the motor power shaft 8 and the motor power shaft second gear 82.
The arrangement of the second motor generator 52 is described in detail below with reference to fig. 2 and 4, and the second motor generator 52 is provided in conjunction with the engine 4. When the second motor generator 52 is used as a motor, the second motor generator 52 may be used to start the engine 4, or the second motor generator 52 may be used to drive the wheels to rotate. When the second motor generator 52 is used as a generator, the engine 4 can drive the second motor generator 52 to generate electric power, and the energy transmitted from the vehicle can drive the second motor generator 52 through the output shaft to generate electric power.
As shown in fig. 1-4, power-driven system 100 may further include: a dual clutch 2d, the dual clutch 2d having an input 23d, a first output 21d and a second output 22d, the input 23d selectively engaging at least one of the first output 21d and the second output 22d, the engine 4 being connected to the input 23 d. Wherein the first output 21d is connected to the first output shaft 21 and the second output 22d is connected to the second output shaft 22. The input 23d is provided with input external teeth, and the second motor generator 52 is linked with the input external teeth. Since the input terminal 23d is connected to the engine 4, the second motor generator 52 and the engine 4 can be interlocked via the input terminal 23 d. A transmission gear connected to the external teeth of the input terminal may be fixedly provided on a motor shaft of the second motor generator 52.
It will be appreciated that the particular engagement state of the dual clutch 2d is influenced by the control strategy, which can be adapted by those skilled in the art according to the actual desired transmission mode, so that it is possible to switch between a plurality of modes in which the input 23d is disconnected from both outputs and the input 23d is engaged with at least one of the two outputs.
As shown in fig. 1 to 4, the second input shaft 12 is sleeved on the first input shaft 11, so that the power driving system 100 is compact in structure, the axial length of the power driving system 100 can be effectively reduced, the size of the power driving system 100 can be smaller, and the power driving system 100 can be conveniently arranged on a vehicle.
As shown in fig. 1 to 4, the first input shaft 11 may be disposed with a first-gear driving gear 1a, a third-fifth-gear driving gear 35a and a seventh-gear driving gear 7a, the second input shaft 12 may be disposed with a second-gear driving gear 2a and a fourth-sixth-gear driving gear 46a, and each gear driving gear rotates synchronously with the corresponding input shaft.
Correspondingly, as shown in fig. 1-4, the first output shaft 21 is provided with a first-gear driven gear 1b, a second-gear driven gear 2b, a third-gear driven gear 3b and a fourth-gear driven gear 4b, the second output shaft 22 is provided with a fifth-gear driven gear 5b, a sixth-gear driven gear 6b and a seventh-gear driven gear 7b, and each gear driven gear is freely sleeved on the corresponding output shaft, i.e. each gear driven gear can rotate with a differential speed relative to the corresponding output shaft.
The first-gear driven gear 1b is engaged with the first-gear driving gear 1a to form a first-gear pair, the second-gear driven gear 2b is engaged with the second-gear driving gear 2a to form a second-gear pair, the third-gear driven gear 3b is engaged with the third-fifth-gear driving gear 35a to form a third-gear pair, the fourth-gear driven gear 4b is engaged with the fourth-sixth-gear driving gear 46a to form a fourth-gear pair, the fifth-gear driven gear 5b is engaged with the third-fifth-gear driving gear 35a to form a fifth-gear pair, the sixth-gear driven gear 6b is engaged with the fourth-sixth-gear driving gear 46a to form a sixth-gear pair, the seventh-gear driven gear 7b is engaged with the seventh-gear driving gear 7a to form a seventh-gear pair, and the first-gear 1b is engaged with the reverse-shaft first gear 31.
Wherein the four-gear pair and the six-gear pair share the four-six-gear driving gear 46a, and the three-gear pair and the five-gear pair share the three-five-gear driving gear 35a, so that two gear driving gears can be reduced, the structure of the power driving system 100 is more compact, and the axial size is smaller.
Because the driven gear and the output shaft are in an empty sleeve structure, a synchronizer is required to be arranged to synchronize the corresponding driven gear and the output shaft so as to realize power output.
In some embodiments, and as shown in conjunction with fig. 1-4, the powertrain system 100 includes a three-gear synchronizer 13c, a two-four gear synchronizer 24c, a five-seven gear synchronizer 57c, and a six-gear synchronizer 6 c.
As shown in fig. 1, a three-speed synchronizer 13c is provided on the first output shaft 21 between the first-speed driven gear 1b and the third-speed driven gear 3b, and the three-speed synchronizer 13c can engage the first-speed driven gear 1b or the third-speed driven gear 3b with the first output shaft 21 so as to enable the synchronous rotation of the driven gears and the output shafts.
For example, as shown in fig. 1, moving the engaging sleeve of the first three-speed synchronizer 13c leftward engages the third driven gear 3b with the first output shaft 21, so that the third driven gear 3b and the first output shaft 21 can rotate synchronously. The rightward movement of the engaging sleeve of the first-third synchronizer 13c engages the first-speed driven gear 1b with the first output shaft 21, so that the first-speed driven gear 1b and the first output shaft 21 can rotate synchronously.
Similarly, as shown in fig. 1, a two-fourth-speed synchronizer 24c is provided on the first output shaft 21 between the two-speed driven gear 2b and the four-speed driven gear 4b, and the two-fourth-speed synchronizer 24c can engage the two-speed driven gear 2b or the four-speed driven gear 4b with the first output shaft 21 so as to enable the synchronous rotation of the driven gears and the output shafts.
For example, as shown in fig. 1, moving the engaging sleeve of the second-and-fourth-speed synchronizer 24c leftward engages the second-speed driven gear 2b with the first output shaft 21, so that the second-speed driven gear 2b rotates in synchronization with the first output shaft 21. The rightward movement of the engaging sleeve of the second-and-fourth-speed synchronizer 24c engages the fourth-speed driven gear 4b with the first output shaft 21, so that the fourth-speed driven gear 4b rotates in synchronization with the first output shaft 21.
Similarly, as shown in fig. 1, a fifth-seventh speed synchronizer 57c is provided on the second output shaft 22, the fifth-seventh speed synchronizer 57c is located between the fifth-speed driven gear 5b and the seventh-speed driven gear 7b, and the fifth-seventh speed synchronizer 57c is used to engage the fifth-speed driven gear 5b or the seventh-speed driven gear 7b with the second output shaft 22, for example, if the engaging sleeve of the fifth-seventh speed synchronizer 57c is moved rightward, the seventh-speed driven gear 7b can be engaged with the second output shaft 22, so that the seventh-speed driven gear 7b rotates synchronously with the second output shaft 22. For another example, when the engagement sleeve of the fifth-seventh-speed synchronizer 57c moves leftward, the fifth-speed driven gear 5b is engaged with the second output shaft 22, and the fifth-speed driven gear 5b rotates in synchronization with the second output shaft 22.
Similarly, as shown in fig. 1, a sixth-speed synchronizer 6c is provided on the second output shaft 22, the sixth-speed synchronizer 6c is located on one side, for example, the left side, of the sixth-speed driven gear 6b, and the sixth-speed synchronizer 6c is used to engage the sixth-speed driven gear 6b with the second output shaft 22, for example, the engaging sleeve of the sixth-speed synchronizer 6c moves to the right, so that the sixth-speed driven gear 6b can be engaged with the second output shaft 22, and thus the sixth-speed driven gear 6b rotates synchronously with the second output shaft 22.
In some embodiments, as shown in fig. 1, the second gear drive gear 2a, the fourth-sixth gear drive gear 46a, the third-fifth gear drive gear 35a, the first gear drive gear 1a, and the seventh gear drive gear 7a are located at increasing distances from the engine 4. Thus, the gear arrangement is more reasonable, the power drive system 100 is more compact, and the radial and axial dimensions are relatively smaller.
For the power drive system 100 in which the reverse output gear 39 is fixedly provided on the second output shaft 22, the reverse shaft first gear 31 is freely fitted on the reverse shaft 3, and the reverse shaft 3 is provided with the reverse shaft first synchronizer 3c for engaging the reverse shaft first gear 31, wherein the sixth gear synchronizer 6c is located on the left side of the sixth gear slave gear, and the reverse shaft first synchronizer 3c is located on the right side of the reverse shaft first gear 31, so that the reverse shaft first synchronizer 3c and the sixth gear synchronizer 6c can share the same shift fork mechanism, when the shift fork mechanism drives the reverse shaft first synchronizer 3c to engage the reverse shaft first gear 31, the sixth gear synchronizer 6c is disengaged from the sixth gear slave gear 6b, and when the shift fork mechanism drives the sixth gear synchronizer 6c to engage the sixth gear slave gear 6b, the reverse shaft first synchronizer 3c is disengaged from the reverse shaft first gear 31. Specifically, when the clutch sleeve is moved leftward by the fork mechanism, the reverse shaft first synchronizer 3c engages the reverse shaft first gear 31 and the six-gear synchronizer 6c is disengaged from the six-gear driven gear 6b, and when the clutch sleeve is moved rightward by the fork mechanism, the six-gear synchronizer 6c engages the six-gear driven gear 6b and the reverse shaft first synchronizer 3c is disengaged from the reverse shaft first gear 31. Therefore, a shifting fork mechanism can be omitted from the power driving system 100, so that the power driving system 100 is simple in structure and light in weight.
