First gear 204 hangs N gears, and when hub 101 of shifting gears rotates forward certain angle, the second gear 205 hangs L gears, now drives
Motor has hung up gear, and vehicle can be with pure electronic starting, the first gear when hub 101 of shifting gears continues to rotate forward certain angle
204 extensions 1 keep off and the second gear 205 is maintained at L gears.During the first gear 204 is put into gear, main clutch 206
Operation also can coordinate simultaneously to carry out, to complete process of normally putting into gear.
During the gearshift reversion certain angle of hub 101, the second gear 204 hangs L gears, and the reversion by motor 202 is electronic
Pattern realizes reversing.Can also arrange in the first gear 204 and individually reverse gear, be moveed backward by motor-powered vehicle, but
It is not limited thereto system.
As shown in figure 3, when gearshift hub 101 is hung in the second gear 205, L keeps off and the first gear 204 is maintained at N gears
Angle continue reversion certain angle when, the first gear 204 hang 1 gear and the second gear 205 hang N gear.So ensure
Mixed power plant also has cyllopodia returning function, i.e., when electrical storage device or motor break down, electromotor is still
1 gear can be hung drives vehicle to go home.
As shown in Fig. 2 shift motor 102 is motor.Shift motor 102 can also using other kinds of motor come
Realize, as long as which disclosure satisfy that the torque or power for driving gearshift hub 101, and the requirement of positional precision, not with this
To limit.Additionally, shift motor 102 can also be made up of two less motor parallel connections, which can be with external in gearshift hub
101 outside, it is also possible to installed in the inside of gearshift hub 101, be not limited thereto system.
By dividing for selector fork 2041 or 2042 lock unit for driving and the main clutch 206 driven by disengaging yoke 2061
From or engaging process characteristic be it is different, shift motor 102 according to gearshift hub 101 rotate angle carry out speed Control, with
Process control requirements needed for meeting.The contour curve of three slideways 1011,1012,1013 can also be special according to required difference
Property is designed, and is not limited thereto system.
As shown in Fig. 2 also including including the mixed power plant 200 of gearshift 100:Electromotor 201, accessory belt pulley
It is 210, motor 202, main reducing gear driven gear 203, the first gear 204, the second gear 205, power transmission shaft
207 and electromagnetic clutch 208;
Electromotor 201 is connected with main reducing gear driven gear 203 by the first gear 204, with by the first speed change
Mechanism 204 provides the first power to main reducing gear driven gear 203;
Motor 202 is connected with main reducing gear driven gear 203 by the second gear 205, to become by second
Fast mechanism 205 provides the second power to main reducing gear driven gear 203;
Electromotor 201 is connected with accessory belt train 210, to drive accessory belt train 210 to rotate;
Accessory belt train 210 is connected with power transmission shaft 207 by electromagnetic clutch 208, power transmission shaft 207 and motor
202 connections.
Wherein, the power of motor 202 is applied to main reducing gear quilt not over the inside of the first gear 204
On moving gear 203, but it is applied on main reducing gear driven gear 203 by the inside of the second gear 205, it is ensured that right
The change of existing variator is minimum;And in vehicle parking, the power of electromotor 201 is delivered to by accessory belt train 210
On power transmission shaft 206, motor 202 is then driven to generate electricity, it is ensured that on the premise of minimum is changed to existing variator
Idling generating function is provided, the electric quantity balancing of electrical storage device is effectively maintained.
Electromotor 201 and motor 202 drive the first gear 204 and the second gear 205, two-way to drive respectively
Power is superimposed rear-guard motor-car, therefore the first gear 204 and the second gear on main reducing gear driven gear 203
205 can be operated according to its respective gear shifting characteristic, when a gear is shifted gears wherein, another gearshift machine
Structure is avoided while shift gears, then can ensure that power does not interrupt gearshift, or even accelerates in gearshift, raising power performance.And
During parking, the second gear 205 hangs neutral, then contact cut-off between motor 202 and wheel, by power transmission shaft
The power of 207 electromotors 201 for transmitting can just drive motor 202 to be generated electricity.
Motor 202 is added on existing variator, inevitably need change variator housing, and if
Variator manufacturer is also ready to further carry out appropriate modification to form more suitably product, then the first gear 204
Need to keep off with 1 gear, 2 gears, 3 gears and 4 with 4 forward gears, i.e. the first gear 204, and 205 need of the second gear
There is 2 forward gears, i.e. the second gear 205 with L gears and H gears, the complexity of mixed power plant can be so reduced
Property and cost.
A kind of speed ratio of the gear 1/2/3/4/5/R of typical 5 gear change speed gear box is followed successively by:3.583、2.105、1.379、
1.030th, 0.820, -3.363, base ratio is 3.722.In the case where base ratio is constant, this specific embodiment first becomes
The speed ratio of the gear 1/2/3/4 of fast mechanism 204 could be arranged to:2.105、1.379、1.030、0.820.The speed ratio of each gear
Can be other numerical value, can select according to the actual requirements to arrange, be not limited thereto system.
The speed ratio of the L gears and H gears of the second gear 205 can be arranged to:2.105 with 1.030.Due to motor
The rotating speed of the 202 corresponding rotating ratio electromotor of gearshift 201 is high, therefore can avoid when the first gear 204 is shifted gears the
Two speed-changing mechanism 205 is also shifted gears, so as to avoid shifting power from interrupting, it is also possible to utilize identical gear as far as possible.
Using above-mentioned gearshift and mixed power plant, realize to electromotor due to wherein by a gearshift hub
The speed Control of the first gear for carrying out speed change and the second gear that speed change is carried out to motor, it is only necessary to be equipped with
One shift motor, simple structure significantly reduce the complexity of mixed power plant gearshift, are also convenient for the later stage and are tieed up
Repair maintenance.
