Need to control speed change box clutch simultaneously and be in an off state, thus motor can directly by differential mechanism progress power output without
Gearbox need to be passed through, reduce energy loss；When the control module control speed change box clutch of hybrid power system is in closed form
When state, while the input shaft for needing to control the power clutch mechanism and differential mechanism disconnects, so that motor can pass through speed change
Case imparts power to differential input shaft, due to including shifting gear in gearbox, so that entire hybrid power system can
Obtain biggish power performance.As can be seen that hybrid power system provided by the embodiment of the present invention, due to hybrid power system
Control module can select a control power clutch mechanism and the speed change box clutch, it is thus possible to needing to reduce energy damage
When work consuming condition selection closure power clutch mechanism, and when needing to improve power performance operating condition selection disconnect power clutch mechanism with
Increase gearbox gear, ensure that motor can between different mode free switching, to widen hybrid power system
Operating condition application, the accuracy of control is also ensured, at the same time it can also prevent two power transmission paths while being moved
The generation for the phenomenon that power is transmitted, improves the safety of power transmission.

In the present embodiment, gearbox the first synchronization mechanism A1 and the second synchronization mechanism of gearbox A2 are fixed on the gearbox
On second input shaft S2, fixed form can be spline connection, be also possible to that gearbox synchronous gear mechanism is directly welded to speed change
On the second input shaft of case S2.
In the present embodiment, it is illustrated by taking 6 gear gearboxes as an example.By setting 6 gears, Neng Gougen in gearbox
Need to select the gear pair of different stalls to carry out power transmission according to different power, the deceleration torque increase of the gear pair of different stalls
Ratio is different, to increase speed alternative.
Because use 6 gear gearboxes, therefore by the first synchronization mechanism of gearbox A1 be set to the first driven shifting gear D1 and
Between the driven shifting gear D3 of third, by the second synchronization mechanism of gearbox A2 be set to the 5th driven shifting gear D5 and second from
Between dynamic shifting gear D2, by gearbox third synchronization mechanism A3It is set to the 4th driven shifting gear D4 and the 6th driven gear
Between gear D 6.Specifically, gearbox the first synchronization mechanism A1 corresponds to the first driven shifting gear D1 and the driven gear of third
Gear D 3, gearbox the second synchronization mechanism A2 correspond to the 5th driven driven shifting gear D2 of shifting gear D5 and second, speed change
Case third synchronization mechanism A3 corresponds to the 4th driven driven shifting gear D6 of shifting gear D4 and the 6th.
In this way, multiple active shifting gears and multiple driven shifting gears are engaged with each other to form and respectively correspond multiple gears
Gear pair, multiple synchronization mechanisms can with corresponding shifting gear engage or disconnect engagement to realize gear shift.So as to root
Need to select the gear pair of corresponding gear according to operating condition, to increase power transmission torque.Due to each shifting gear in gearbox 60
It may be incorporated for motor 10 and engine 30, hybrid power system can obtain more fixed speed ratios, so that hybrid electric vehicle
Can power performance and the economy performance obtain preferably balance.
In a specific embodiment, the hybrid power system further include:
Transmission mechanism 70 is fixed between engine 30 and the speed change box clutch 40.
Specifically, as shown in Fig. 2, in one embodiment, the transmission mechanism 70 can be belt wheel.Belt wheel can get compared with
Long service life.Certainly, in other embodiments, the transmission mechanism 70 can also be chain conveyer, to reduce transmission process
In noise.
With continued reference to Fig. 2, hybrid power system further include:
Engine clutch 80 is set between the engine 30 of the hybrid power system and the transmission mechanism 70.
Engine clutch 80 is used to disconnecting or connecting the power transmission between engine 30 and wheel, in 10 work of motor
Make in the idle situation of engine 30, can prevent motor 10 from dragging to the counter of engine 30, to save 10 energy of motor damage
Consumption.
To solve the above-mentioned problems, the embodiment of the present invention also provides a kind of hybrid vehicle, including wheel and above-mentioned
Hybrid power system, the wheel are connected with the output shaft of the differential mechanism.
Since the hybrid vehicle includes above-mentioned hybrid power system, thus have and above-mentioned hybrid power system phase
Same effect and effect, specifically please refers to above, details are not described herein.
Although the embodiment of the present invention discloses as above, present invention is not limited to this.Anyone skilled in the art, not
It is detached from the spirit and scope of the present invention, can make various changes or modifications, therefore protection scope of the present invention should be with right
It is required that subject to limited range.
