Position, the second axis synchronizer gearshift 151 still be in left gear, when the first axle synchronizer gearshift 141 from
After left shift transformation is linked into intermediate gear, then the left shift gear 142 of the first axle and the right shift gear 143 of the first axle will
It can turn in support needle roller overhead, not transmit power.Also, at the same time, second motor 221 continues to keep power drive vehicle
Traveling, pass through above-mentioned transformation realize power continuous change gearshift function.
Specifically, the second axis synchronizer gearshift 151 can also be linked into intermediate gear from left shift transformation, this
When, the left shift gear 152 of the second axis and the right shift gear 153 of the second axis turn in support needle roller overhead, do not transmit power.Accordingly
, at the same time, the first motor 211 continues to keep power drive vehicle driving, and the company of power is realized by above-mentioned transformation
Continuous gear shift function.
Specifically, first shift speed change mechanism 14 and the second shift speed change mechanism 15 are not only in above-mentioned implementation
It is one group, is also possible to multiple groups, i.e., first shift speed change mechanism 14 can be realized two or three or four gear tune
Section, the second shift speed change mechanism 15 can be realized two or three or four gears are adjusted, therefore the first shift speed change mechanism
14 and second shift speed change mechanism 15 can there are many modes being freely combined to realize the various gear continuous changes of automobile, it fits
Realize that three gears are adjusted for various, such as the first shift speed change mechanism 14, the second shift speed change mechanism 15 realizes four
A gear is adjusted, so that the continuous change that 7 gears may be implemented in applicable vehicle is adjusted, it is preferable that in the present embodiment, first
Shift speed change mechanism 14 and the second shift speed change mechanism 15 can be realized two gear shifts and adjust, it is to be understood that described
When first shift speed change mechanism 14 or the second shift speed change mechanism 15 realize the adjusting of three gears, first shift
Gear 14 or the second shift speed change mechanism 15 are two groups, and having one group only includes a left shift gear or a right gear
Position gear, also, first shift speed change mechanism 14 and the realization of the second shift speed change mechanism 15 be three gears adjust or
When four gears are adjusted, the function and specific implementation principle that can be realized and the function and principle phase of realizing that two gears are adjusted
Together, which is not described herein again.
Further, in the present embodiment, first electric module 21 and the second electric module 22 can also be distinguished
The two sides of shift speed change module 1 are set, and are only the installation sites of the first electric module 21 or the second electric module 22
Change, and the connection connection relationship of shift speed change module 1 is identical as the connection relationship of above-mentioned specific descriptions, the function realized
Can and principle also identical which is not described herein again.
Embodiment 2:
Another structure of the continuous change electric gear shift(ing) is given in the present embodiment referring to Fig.2, the present embodiment with
Unlike embodiment one, first electric module 21 is wholely set with the second electric module 22, second shift speed change
Mechanism 15 further includes intermediate gear 16, and the intermediate gear 16 is connect by transmission gear 17 with second electric module 22,
The intermediate gear 16 is supported on second input shaft 12 by third needle bearing.
Specifically, in the present embodiment, first shift speed change mechanism 14 also can be realized one grade, three gears and neutral gear gear
Position, second shift speed change mechanism 15 also can be realized second gear, four gears and neutral gear.Specifically, different from embodiment
Be, above-mentioned second gear and four keep off power transmitting in, second motor 221 be different from embodiment one in directly pass through second
Input shaft transmits power, but the power of second motor 221 is passed to intermediate gear 16 by transmission gear 17, and then lead to again
It crosses intermediate gear 16 and the power of second motor 221 is passed into second input shaft 12, to be passed again by the second input shaft
Graduating power.Specific transfer principle is identical with embodiment one, and which is not described herein again.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
