In addition, for various mode of operations, rotary clutch 4, brake coupling 5 and motor 2 it is specific
Operate and shown in table 1, wherein, ◆ and ◇ represents that the locking of clutch or mechanical brake is conciliate respectively
Lock status.
The mode of operation of the hybrid electric drive system of table 1
Below, will be described in detail the driving conditions of each specific works pattern, operating method, state with
And power flow.
1) pure electric Drive Mode
When running resistance and car speed is relatively low and during sufficiently high dump energy of battery, mixing is dynamic
Power automobile is only driven by motor 2, i.e. operated with pure electric Drive Mode.In this drive pattern
Under, as shown in Figure 2 a, engine 1 is closed down, and rotary clutch 4 is opened, and brake coupling 5
Closure.So as to which motor 2 is delivered to as the power of motor operation from its rotor by sun gear S
Planet carrier C, then passes sequentially through the main reducing gear 8 being connected with planet carrier C, connects with main reducing gear 8
The driving moment that the differential mechanism 9 that connects and being eventually transferred to is connected with differential mechanism 9, to drive vehicle.Figure
Arrow in 2a shows the transfer mode of power flow.
2) pure engine drive mode
When running resistance and of a relatively high car speed, hybrid vehicle is only driven by engine 1
It is dynamic, i.e. to be operated with pure engine drive mode.In that driving mode, as shown in Figure 2 b, revolve
Clutch 4 is left to close, and brake coupling 5 is opened.Now, gear ring R, planet carrier C and the sun
Wheel S is fixed together, therefore, and planetary gearsets 3 play a part of directly driving axle.The quilt of motor 2
Close down and with engine 1 together with identical speed rotate.So as to which the power of engine 1 is bent from it
Axle is sequentially delivered to planetary gearsets 3, main reducing gear 8, differential mechanism 9 by shock absorber 6 and finally passed
Driving moment is delivered to, to drive vehicle.Arrow in Fig. 2 b shows the transfer mode of power flow.
3) combination drive pattern
Specifically include two distinct types of combination drive pattern：Combination drive pattern I and combination drive
Pattern II.
Combination drive pattern I
When running resistance height but low car speed, such as under the conditions of all one's effort accelerates or climbs, mixing
Power vehicle is driven jointly by engine 1 and motor 2.In this case, motor 2 is as electronic
Machine is operated, so that, the power that maximum is provided can be travelled for vehicle.If however, driving dynamics demand
It is not that so high and battery dump energy is relatively low, the excess power of engine 1 can also be used in motor 2
As generator operation, to be charged for battery.In a word, motor 2 can be used for working drive system
Efficient region is arrived in point regulation.
In combination drive pattern I, as shown in Figure 2 c, rotary clutch 4 is closed, braking clutch
Device 5 is opened, therefore, and planetary gearsets 3 play a part of directly driving axle, motor 2 and engine 1
Rotated together with identical speed.So as to, when motor 2 is as motor operation, engine 1 it is dynamic
The power of power and motor 2 is delivered to the planet carrier of planetary gearsets 3 from gear ring R and sun gear S respectively
C, is then sequentially delivered to main reducing gear 8, differential mechanism 9 and is eventually transferred to driving moment, to drive
Vehicle.Arrow in Fig. 2 c shows the transfer mode of power flow.
Combination drive pattern II
When running resistance height and also high car speed, such as under the conditions of high-ball, hybrid power
Automobile is also driven jointly by engine 1 and motor 2.Under combination drive pattern II, such as Fig. 2 d
Shown, rotary clutch 4 and brake coupling 5 are opened, and hybrid electric drive system is in the pattern
Under serve as the electronic infinite variable speed device (EVT) with two frees degree.No matter car speed and load have
How is body, and additional one degree of freedom can make deep hybrid power automobile/plug-in hybrid-power automobile
Its efficient region is arrived into the speed regulation of engine 1 with greater flexibility.According to engine speed
Degree requires that motor 2 can be used as motor or generator operation.It is similar with combination drive pattern I,
When motor 2 is as motor operation, the power of engine 1 and the power of motor 2 are respectively from gear ring R
The planet carrier C of planetary gearsets 3 is delivered to sun gear S, be then sequentially delivered to main reducing gear 8,
Differential mechanism 9 is simultaneously eventually transferred to driving moment, to drive vehicle.Arrow in Fig. 2 d shows power
The transfer mode of stream.
4) braking mode
Specifically include three kinds of different types of braking modes：Mechanical braking pattern, braking mode and
Composite braking pattern.
Mechanical braking pattern
Under mechanical braking pattern, by discharging rotary clutch 4 and brake coupling 5 simultaneously, by institute
There is braking moment to be applied to mechanical brake 10 by leverage, as shown in Figure 2 e.
Braking mode
In a regenerative braking mode, engine 1 is closed down, and motor 2 is as generator operation and passes through
Locking brake coupling 5 provides regenerative braking moment.It can thus be seen that power flow is in regenerative braking
With the contrast under pure electric Drive Mode under pattern, as shown in figure 2f.
Composite braking pattern
Mechanical braking pattern and braking mode are combined into composite braking pattern, so as in motor 2 not
Feedback more braking energies when energy provides whole required braking moment, as shown in Figure 2 g.
5) stopping for charging pattern
When battery needs charging, such as accelerate with all strength by prolonged under combination drive pattern or
When climbing and the dump energy of battery is reached lower limit, hybrid electric drive system of the invention can also be carried
For the possibility of stopping for charging.Under stopping for charging pattern, rotary clutch 4 and brake coupling 5
Open, and mechanical brake 10 is closed.The power of engine 1 passes through the He of shock absorber 6 from its bent axle
Planet carrier C is delivered to sun gear S, and being then passed to motor 2 makes it as generator operation to electricity
Pond is charged, as shown in Figure 2 d.
It can thus be seen that the hybrid electric drive system of the present invention is fairly simple, it uses list
Individual planetary gearsets, single motor, a brake coupling and a rotary clutch.By these
The combination of the different operating of part, realizes a variety of different mode of operations and suitable for different travelings
Condition.So as to reduce the defect of existing single motor and many electric machine mixed power drive systems, i.e.,
The hybrid electric drive system of the present invention has relatively low cost and system complexity, while again not sacrificial
Any power performance of domestic animal and economic performance.Specifically, system cost reduction but no sacrifice automobile
Can, mechanically and electrically the system integration difficulty in terms of power is reduced, and due to using only an electricity
Machine is with the mixed power coupling device simplified so that hybrid electric drive system has more compact chi
It is very little.Especially, hybrid electric drive system of the invention can still realize pure driven by power.
For those skilled in the art, hybrid electric drive system of the invention obviously can also be answered
For other suitable application scenarios, it is not limited to hybrid vehicle.
Moreover, for a person skilled in the art, other advantages of the invention and alternative implementation
Mode is obvious.Therefore, shown in the present invention is not limited to for its wider range of meaning
With described detail, representative configurations and exemplary embodiment.On the contrary, those skilled in the art
Various modifications and substitutions can be carried out in the case where not departing from the essence spirit and scope of the present invention.
