, link 10 is made to be fixed from rotating.The utility model is turned by one-way clutch 9 and two lockable mechanisms to carry out pattern
It changes, can realize multiple-working mode under less variable-speed unit：
(1) the first pure electric drive of motor (middle low torque operating mode) process：One-way clutch 9 is in separated position, the first lock
Locking mechanism 11 is in lockup state, and engine 1 is closed, and the second motor 4 is closed, and the first motor 3 works, the transmission of output torque
Direction is exported from the first motor 3, and the second sun gear 8a is passed to, then pass to planet by the second planetary gear 8b by motor shaft
Frame 6 is transmitted finally by output shaft 5 and is exported.Such pattern is because only that 3 independent role of the first motor, therefore torque is limited, uses
It works under the operating mode of torque in ground；
(2) first motors and the second pure electric drive of motor bi-motor (high torque operating mode) process, one-way clutch 9, which is in, to be divided
Open state, the first lockable mechanism 11 are in lockup state, and engine 1 is closed, and the second motor 4 works, and the first motor 3 works, defeated
Go out torque and be divided into two lines, first torque transfer route, the first motor 3 generates torque and passes to second too by motor shaft
Sun wheel 8a, then planet carrier 6, Article 2 torque transfer route are passed to by the second planetary gear 8b, the second motor 4 generates torque,
First sun gear 7a is directly passed to by motor transmission shaft, planet carrier 6 is then passed to by the first planetary gear 7b again, two
Torque on route merges, and is transmitted export by output shaft 5 together.Under such pattern, opened due to the second motor 4 and instantaneously passed through
First sun gear 7a generates a reversed trend, is at this moment equivalent to the first gear ring 7c and fixes, and planet carrier 6 is rotating in the forward direction, this
When the first gear ring 7c also can by the active force of a negative direction, since the operation principle of one-way clutch 9 is that negative direction locks,
Therefore 1 and first gear ring 7c of engine can effectively be prevented to reversely rotate, towing astern engine 1；
(3) engine and the first motor parallel driving process, engine 1 is in best efficiency point startup at full speed, drive at this time
First gear ring 7c is also rotated together, and torque passes to planet carrier 6 by the first planetary gear 7b.First lockable mechanism 11 and the simultaneously
Two lockable mechanisms 12 are all in the state of locking, and motionless for fixing the second gear ring 8c and the first sun gear 7a, second is electric at this time
Machine 4 does not work and is locked, and motor MGB work, torque is exported from the first motor 3, and second sun is passed to by motor shaft
8a is taken turns, then planet carrier 6 is passed to by the second planetary gear 8b, the torque that 1 and first motor 3 of engine passes over passes through planet
Frame 6 converges, and is eventually transmitted and exported by output shaft 5.Such paralleling model can meet when engine torque can not meet
When road conditions require, the first motor 3 can be with power-assisted, and when stopping brake, energy can be recycled again by the first motor 3；
(4) engine+E-CVT1 processes, engine is in best efficiency point startup at full speed, the first gear ring 7c of drive at this time
It rotating together, torque passes to planet carrier 6 by the first planetary gear 7b, and the first motor 3 works, and torque is generated from the first motor 3,
Second sun gear 8a is passed to, then pass to planet carrier 6 by the second planetary gear 8b by motor shaft, at this time the second lockable mechanism
12 lockings, the first lockable mechanism 11 are opened, and the work of the second motor 4 generates torque, and first is directly passed to by motor transmission shaft
Then sun gear 7a passes to planet carrier 6 by the first planetary gear 7b again.Three torques collect, and eventually pass through output shaft 5
Transmit output.Under such pattern, the variation of speed and torque passes through two to engine in best efficiency point, vehicle traveling always
The energy that a motor is transmitted is adjusted, and two motors play the role of CVT electrodeless variable-speeds under this system model,
The brake force or reactive torque generated during the speed governing simultaneously is recycled in can also feeding back to corresponding motor；
(5) engine+E-CVT2 processes, engine is in best efficiency point startup at full speed, the first gear ring 7a of drive at this time
It rotating together, torque passes to planet carrier 6 by the first planetary gear 7b, and the first motor 3 works, and torque is generated from the first motor 3,
Second sun gear 8a is passed to, then pass to planet carrier 6 by the second planetary gear 8b by motor shaft, at this time the second lockable mechanism
12 open, 11 locking of the first lockable mechanism, and the second motor 4 generates torque and is divided into two transfer routes, and first is to pass through motor
Transmission shaft is directly passed to the first sun gear 7a, then passes to planet carrier 6 by the first planetary gear 7b again, and Article 2 route is
Second planetary gear 8b is passed to, then pass to planet carrier 6 by the second gear ring 8c, and the energy passed out with the first motor 3 exists
Converge on planet carrier 6, the torque of first route of the second last motor 4, the torque of Article 2 route turn with the first motor 3
After square converges, then transmitted and exported by output shaft 5 together with the torque of engine 1.Under such pattern, engine is always in most
High efficiency point, in vehicle traveling the variation of speed and torque be adjusted by energy that two motors are transmitted, two electricity
Machine plays the role of CVT electrodeless variable-speeds under this system model, at the same the brake force that is generated during speed governing or
Reactive torque can also feed back in corresponding motor and be recycled.Compared to engine+E-CVT1 patterns, engine+E-CVT2
The torque of the second motor 4 is split in pattern, can obtain the rotating speed of the first motor 3 in limited range than map analysis by speed
When, the velocity interval that engine+E-CVT2 patterns do the variable speed carried out is wider, conversely speaking, as fruit product will
It asks and works in certain velocity interval, can drop requirement of the system to the first motor 3 by engine+E-CVT2 patterns
It is low, play cost-effective effect.The hybrid power system of the utility model, in unpowered when multiple-working mode switches
Disconnected, comfort is preferable.
Above-described is only the preferred embodiment of the utility model, it should be pointed out that those skilled in the art is come
It says, under the premise of the utility model structure is not departed from, several modifications and improvements can also be made, these all do not interfere with this reality
With the effect and practical applicability of novel implementation.
