For bottom gear and top gear.
As shown in Figure 3, Figure 4, electronic automobile-used bi-motor two of the present invention keeps off control of the gearbox under low speed gear pattern
Method is：Shift combined cover 5 is detached with two gear pinion gears 6, i.e. the first input shaft 4 is detached with two gear pinion gears 6.First input shaft
4 and second input shaft 7 can individually transmit power to output shaft, be independent of each other.Due to the first motor 1 and the first input shaft
4 are connected, a gear pinion gear 3 and the first input shaft 4 are connected, and a gear pinion gear 3 is engaged with a gear gear wheel 10.Therefore, bottom gear
Under state, the power of the first motor 1 is via first gear to being transmitted to a gear gear wheel 10, and the rotating speed of the first motor 1
Determine the rotating speed of a gear gear wheel 10.At this point, the rotating speed of the first motor 1 of adjustment, to sufficiently high, a gear gear wheel 10 turns
Speed increase therewith reach output rotating speed when, 11 locking of unilateral bearing, and by one gear gear wheel 10 power be transferred to output shaft
12.Since the second motor 8 and the second input shaft 7 are connected, two gear pinion gears 6 and the second input shaft 7 are connected, two gear gear wheels 9
It is connected with output shaft 12, two gear pinion gears 6 are engaged with two gear gear wheels 9.So the power of the second motor 8 output can pass through two
Gear gear mesh is directly delivered to output shaft 12.
Power transmission line under low speed gear pattern is：The power exported by the first motor 1 is successively through the first input shaft
4, it after a gear pinion gear 3, one keeps off gear wheel 10, unilateral bearing 11, is exported by output shaft 12；It is exported by the second motor 8 dynamic

Enter axis 7 to be connected, two gear gear wheels 9 are connected with output shaft 12, and two gear pinion gears 6 are engaged with two gear gear wheels 9, so the first input
Axis 4 and the power of the second input shaft 7 output can by second gear to being directly delivered to output shaft 12, the first input shaft 4 with
Second input shaft, 7 common passing power is via second gear to being transferred to output shaft 12.And under high speed gear pattern, the first input
Axis 4, one keeps off pinion gear 3, two and keeps off pinion gear 6 and 7 rotating speed having the same of the second input shaft.At this point, due to one gear pinion gear 3 with
Two gear pinion gears 6 have same rotational speed, and the transmission ratio of bottom gear is more than top gear, and therefore, the rotating speed of a gear gear wheel 10 is low
In the rotating speed for two gear gear wheels 9 being connected on output shaft 12.Therefore the rotating speed of a gear gear wheel 10 is less than output shaft 12, it is single at this time
To the Internal and external cycle not locking of bearing 11, opposite not passing power of trackslipping.Therefore under high speed gear pattern, first gear is to will not interfere with
Power transmits.
Power transmission line under high speed gear pattern is：The power exported by the first motor 1 is successively through the first input shaft
4, shift combined cover 5, two keeps off pinion gear 6 and is exported by output shaft 12 with after two gear gear wheels 9；It is exported by the second motor 8 dynamic
Power is exported with after two gear gear wheels 9 by output shaft 12 through the second input shaft 7, two gear pinion gear 6 successively.
It is specifically described the shift course of work of two forward gears below：
The shift control process that the electronic gear gearbox of automobile-used bi-motor two rises to top gear from bottom gear is as follows：
Step 1：As shown in figure 4, gearbox is operated in low speed gear pattern：The power exported by the first motor 1 passes through successively
After first input shaft 4, one keeps off the gear of pinion gear 3, one gear wheel 10, unilateral bearing 11, exported by the output shaft 12 of gearbox；By
Two motor 8 output power successively through the second input shaft 7, two gear pinion gear 6, two keep off gear wheel 9 after, by the output of gearbox
Axis 12 exports；
Step 2：As shown in figure 9, reducing the rotating speed of the first motor 1, then the rotating speed of a gear gear wheel 10 is less than output shaft
12, at this time the not locking of unilateral bearing 11, unilateral bearing 11 dally, a gear gear wheel 10 can not will be from the first motor 1 it is dynamic
Power is transferred to output shaft 12；The power exported by the second motor 8 is still kept off via the second input shaft 7, two gear pinion gear 6, two
It after gear wheel 9, is exported by the output shaft 12 of gearbox, this shift process power failure-free；
Step 3：Adjusting the rotating speed of the first motor 1 keeps the first input shaft 4 identical as two gear 6 rotating speeds of pinion gear, at this point,
It manipulates shift combined cover 5 to be combined with two gear pinion gears 6, as shown in fig. 6, gearbox rises to as high speed gear pattern, one keep off greatly at this time
The rotating speed of gear 10 is still below the rotating speed of output shaft 12, and locking, unilateral bearing 11 do not dally unilateral bearing 11 at this time, a gear canine tooth
Power from the first motor 1 10 can not be transferred to output shaft 12 by wheel, and the power exported by the first motor 1 is successively through the
One input shaft 4, shift combined cover 5, two keep off pinion gear 6 and are exported by the output shaft 12 of gearbox with after two gear gear wheels 9；By second
Motor 8 export power successively through the second input shaft 7, two gear pinion gear 6, two keep off gear wheel 9 after, by the output shaft of gearbox
12 outputs.
So far, the electronic automobile-used bi-motor two keeps off gearbox and completes the shift that low speed gear pattern rises to high speed gear pattern
Journey.
