Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
A hybrid system 100 according to an embodiment of the invention is described below with reference to fig. 1 to 11.
As shown in fig. 1 to 10, a hybrid system 100 according to an embodiment of the first aspect of the invention includes: the dual-input-shaft transmission comprises an engine 10, a dual-input-shaft transmission 20, a motor generator 30 and a differential 50, wherein the dual-input-shaft transmission 20 is in power connection with the engine 10 through a clutch 24, and a driving gear 28 is formed on a shell of the clutch 24; the motor generator 30 includes: the motor comprises a motor body 31, a power generation end 32 and a driving end 33, wherein the power generation end 32 is in power connection with the driving gear 28.
The differential 50 is respectively in power connection with the output shaft 23 of the dual-input shaft transmission 20 and the driving end 33 of the motor generator 30; the power generation terminal 32 includes: generate electricity end driven gear 321 and generate electricity end drive gear group 322, generate electricity end drive gear group 322 and gear driving gear or gear driven gear power connection, drive end 33 includes: a drive-end drive gear 331 and a drive-end driven gear set 332, the drive-end driven gear set 332 being in power connection with the differential 50, wherein
The power generation end driven gear 321 and the driving end driving gear 331 are both selectively in power connection with the motor body 31.
Preferably, the power generation-side driven gear 321 and the drive-side driving gear 331 are selectively power-connected to the motor body 31 through the bidirectional synchronizer 40.
Specifically, generator 10 is in power communication with dual input shaft transmission 20 and selectively outputs power toward differential 50, generator end 32 of motor generator 30 is in power communication with a range driven gear or range driving gear, and drive end 33 is in direct power communication with differential 50.
Furthermore, based on the fact that the motor generator 30 is directly connected to the gear driving gear or the gear driven gear, during the starting process of the engine 10, the motor generator 30 can perform the same function as a starter motor, and meanwhile, the dual-input shaft transmission 20 has at least two gears, compared with the single-gear hybrid power system 100, the working efficiency of the engine 10 is higher, so that the engine 10 can still drive the vehicle 1000 to run within the full vehicle speed range, and compared with the conventional power vehicle 1000, the transmission has smaller volume and is convenient and simple to arrange.
The power generation end 32 and the driving end 33 are selectively in power connection with the motor body 31 through the bidirectional synchronizer 40, the motor generator 30 provides power towards the differential 50 when the driving end 33 is in power connection with the motor body 31, and the transmission drives the motor generator 30 to generate power when the power generation end 32 is in power connection with the motor body 31.
It can be understood that, the power generation end driven gear 321 and the driving end driving gear 331 are both selectively in power connection with the motor body 31, which means that: in some embodiments, the power generation-side driven gear 321 and the driving-side driving gear 331 are selectively power-connected to the motor body 31 through two-way synchronizers, and in other embodiments, the power generation-side driven gear 321 is power-connected to the motor body 31 through one synchronizer and the driving-side driving gear 331 is power-connected to the motor body 31 through another synchronizer 40.
Meanwhile, the power of the engine 10 and the power of the motor generator 30 are power-coupled on the differential 50.
The hybrid system 100 according to the embodiment of the invention has the following advantages:
