Rotation.
As shown in Fig. 4, when the driving wheel X rotation jointly of engine 1 and first motor 2, the second motor 3 does not work,
The closure of second clutch 6, first clutch 5 disconnect, and synchronizer 4 is connect with second gear 8.Specific energy transmission path can refer to
The energy transmission path of above-mentioned pure engine mode and electric-only mode.It should be noted that this mode is bottom gear, in automobile
So far mode facilitates engine 1 and obtains better fuel economy and more preferably dynamic property for switching when low speed is run.
As shown in Fig. 5, when engine 1 and the second driving wheel X rotation jointly of motor 3, engine 1 and the second motor
3 work, first motor 2 do not work, and the closure of first clutch 5, second clutch 6 disconnect, and synchronizer 4 disconnects.Specific energy passes
Passing path can refer to the energy transmission path of above-mentioned pure engine mode and electric-only mode.This mode is top gear, works as automobile
At a relatively high speed when driving, it can switch to such mode.
Based on above-mentioned, which can be combined by engine 1, first motor 2 and the second motor 3
Running car is driven, the power performance of automobile is improved.Also, the power by exporting engine 1, first motor 2, second
The mechanical energy that motor 3 exports couples at the 7th gear 17, can enable the power phase between first motor 2 and engine 1
Mutually supplement works that (best fuel oil region refers to: mentioning with minimum oil consumption to guarantee that engine 1 is in best fuel oil region
For the region of maximum power).
Increasing journey mode is enabled when 1 fuel consumption of engine is larger, working efficiency is lower, in order to give full play to engine
Energy extra in engine 1 is converted to electric energy by increasing journey mode, then passes through electric energy by the energy that fossil fuel discharges in 1
Wheel X rotation is driven, the service efficiency for improving fossil fuel is conducive to.
In increasing journey mode, as shown in Fig. 6, first clutch 5 and second clutch 6 are disconnected, synchronizer 4 and first
Gear 7 connects, and provides electric energy to first motor 2 by engine 1 and the second motor 3 and battery pack 10, and pass through the first electricity
Machine 2 drives wheel X rotation.Specifically, 1 output power of engine makes the synchronized device 4 of the power, first gear 7, the 4th gear
13 are transferred to the second motor 3, using the second motor 3 by the power-conversion be electric energy, and by a part of electric energy be transferred to first electricity
Machine 2 drives wheel X rotation by first motor 2；And another part electric energy is transferred to inverter 9, it will be handed over using inverter 9
Galvanic electricity is converted to direct current, charges for battery pack 10.
The increasing journey mode can realize the uncoupled dynamic space of engine 1, first motor 2 and the second motor 3, and engine 1 is made to work
In high efficient district.The mode is used in low speed and lower battery dump energy value, and the fuel economy of automobile can be improved.
In energy recuperation mode, as shown in Fig. 7, engine 1 and the second motor 3 do not work, synchronizer 4, first from
Clutch 5 and second clutch 6 disconnect, and convert electric energy for mechanical energy by wheel X and first motor 2, and be stored in battery
In group 10.The mechanical energy that automobile is generated when sliding or braking is from wheel X through the 9th gear 19, the 6th gear 16, the 7th gear
17, eighth gear 18 is transferred to first motor 2, so that first motor 2 is generated electricity, and electric energy is transferred to inverter 9, utilizes inverter
9 convert alternating current to direct current, transmit the direct current and store into battery pack 10.
It is braked under electric-only mode, first clutch 5 and second clutch 6 are in an off state, first motor 2 and hair
Motivation 1 decouples, and for engine 1 without towing astern, the effect that recovers energy is good.Engine 1 and first motor 2 do not solve under mixed dynamic model formula
Coupling will cause engine towing astern phenomenon, influence energy regenerating effect when recovering energy, when automobile needs are longer under mixed dynamic model formula
When time brakes, such as persistently descending operating condition, first clutch 5 or second clutch 6 can be disconnected according to the mixed dynamic model formula of difference, it will
First motor 2 and engine 1 decouple the energy regenerating effect realized.
To sum up, hybrid power system provided in an embodiment of the present invention reduces by using the arrangement of parallel axle construction
Axial tooth cun, while adjusting the position of first clutch 5, second clutch 6 and synchronizer 4, make system have two it is solid
Constant-speed ratio shelves improve the fuel economy of vehicle.
The foregoing is merely illustrative embodiments of the invention, the protection scope being not intended to limit the invention is all at this
Within the spirit and principle of invention, any modification, equivalent replacement, improvement and so on should be included in protection model of the invention
