Train is exported to differential mechanism 63 and wheel.
High-grade combination drive operating condition (its power flow is as shown in Figure 7): brake 625 is in releasing orientation, at clutch 626
In bonding state, internal combustion engine 5 issues power input to the first planetary gear train, and the first planetary gear train shunts power, and one
Divide power output to first motor 61, makes the work of first motor 61 in generating state, the mechanical energy of internal combustion engine 5 is eventually converted into
Electric energy is input in power battery 1 or for directly driving the second motor 64；Another part power can by the first gear ring 6211,
First gear 6231, second gear 6232 are transferred to the second gear ring 6221, while can be transferred to the 4th by third gear 6241
Gear 6242 can carry out torque couple with the movement from the second motor 64 at this time, and directly pass through clutch 626, second too
Positive wheel shaft 630 is transferred to the second sun gear 6224, and two-way power is finally collaborated in the second planetary gear train, and by main reduction
Gear 627 is output to differential mechanism 63 and wheel.Certainly, it can both be passed to by the 4th gear 6242 in above-mentioned power transmittance path
Third gear 6241 can also be transmitted to the 4th gear 6242 by third gear 6241, and the torque for depending on speed changer distributes
Strategy.
Low-grade, high-grade Brake energy recovery operating condition: entering on-position from driving condition, can carry out energy by the second motor 64
Amount recycling.When vehicle is reduced to some threshold value from fast state, control system acts on and vehicle is made to enter lower-speed state, at this time
Due to having two groups of different speed ratios, it can thus optimize the energy efficiency under damped condition, the second motor 64 is allow to exist
It effectively generates electricity, and is stored into power battery 1 under lower speed.Meanwhile under two kinds of Brake energy recovery operating conditions, braking is opened
Mechanical changeover or hydraulic part movement are not all needed when the beginning, to there is preferable driving sensation.
Switching between the above various low-grade operating conditions and high-grade operating condition, is to control clutch and system by hydraulic control portion
The working condition of dynamic device, shift process do not have a power interruption, switching of second motor 64 between driving condition to generating state,
The adjusting for pertaining only to second motor 64 itself control parameter does not need to carry out mechanical switch, will not thus generate shift punching
It hits, makes the more flexible agility of switching between operating condition, driving sensation is better；Switching time between operating condition, switching action simultaneously
Speed, handoff procedure torque the operating parameters such as control, can be determined by the calibration of speed changer.

626 and brake 625 connect and control its working condition, so that brake 625 be in normally off, clutch 626 is in normally opened
State, the i.e. Low gear state of speed changer；Clutch oil cylinder 107 and brake oil cylinder 108 share a set of oil pump 102 and oil pump simultaneously
Motor 103 can reduce manufacturing cost in this way.Certainly, two sets of oil pumps 102 and Oil pump electrical machinery 103 can also be used control respectively from
Clutch oil cylinder 107 and brake oil cylinder 108 (specific as shown in Figure 10), although cost of manufacture will increase in this way, can divide
Not Kong Zhi clutch 626 and brake 625 working condition, be allowed to more flexible.
It is illustrated in figure 9 the sequence of movement schematic diagram of brake and clutch, as seen from the figure, when working connection pressure rise
When, brake 625 can first unclamp, and then clutch 626 gradually combines, and speed changer steps into high-grade operating condition, can avoid in this way
When clutch 626 transfers power to the second sun gear 6224, the second sun gear 6224 is still within all or part of on-position,
Brake 625 or clutch 626 is caused to generate the unfavorable movement of improper sliding wear；And when working connection pressure reduction, clutch
626 can first separate, and then brake 625 gradually combines, and can avoid clutch 626 in this way and still transfer power to the second sun gear
6224, so that the second sun gear 6224 is still within all or part of on-position, brake 625 or clutch 626 is caused to generate
The unfavorable movement of improper sliding wear.
