Ring, different synchronous lock rings can be meshed from the different second gears 404 of the both sides of synchronizer 50 so that clutch collar with not
After the synchronous lock ring connection that same second gear 404 is meshed gear 100 can be made to perform different gears, avoid one
Individual clutch collar can only lock ring synchronous with one be connected perform a gear and increase the quantity of synchronizer 50, effectively reduce
The quantity of synchronizer 50, makes product with compact structure, has saved production cost, and meets the needs of product structure miniaturization, lifting
The competitiveness of product in market.
According to second aspect embodiment of the present utility model, it is also proposed that a kind of automatic transmission, including any of the above-described skill
Gear 100 described in art scheme.
The automatic transmission that the embodiment of the utility model second aspect provides, including described in any of the above-described technical scheme
Gear 100.The automatic transmission that the embodiment of the utility model second aspect provides including first aspect embodiment because carrying
The gear 100 of confession, thus whole advantageous effects of the gear 100 provided with first aspect embodiment,
This is repeated no more.
In one embodiment of the present utility model, it is preferable that also include：Shifting control system, with the phase of gear 100
Connect and realization gearshift is controlled to gear 100.
In this embodiment, automatic transmission also includes shifting control system, passes through shifting control system and gear
100, which are connected and realization is controlled to gear 100, shifts gears so that gear 100 can flexibly, accurately and rapidly
Operated corresponding to performing, so make the gearshift of automatic transmission compared with manual transmission gearshift flexibly, accurate, quick, reliability is high,
It is effectively improved the satisfaction that user uses.Further, shifting control system can be hydraulic control, automatically controlled, electro-hydraulic mixing control
System, or meet other control modes of requirement, the multiple control modes of shifting control system disclosure satisfy that fluid drive
The demand of device different structure, different operating modes, while the use demand of different user is disclosure satisfy that, it is applied widely, improve and use
The satisfaction that family uses.
In summary, the gear and automatic transmission of offer of the present utility model, the shelves of adjacent gear positions number are being performed
During bit map, by different synchronizers 50, second gear 404 corresponding with current gear is separated respectively, with target gear pair
The second gear 404 answered is mutually close so that when synchronizer 50 departs from second gear 404 corresponding to current gear, different synchronizations
The second gear 404 corresponding with target gear of device 50 is meshed performance objective gear, avoid in the prior art with current gear
The second gear 404 corresponding with current gear of synchronizer 50 that corresponding second gear 404 is meshed separates rear idle stroke operation
After performing neutral gear, synchronizer 50 close to second gear 404 corresponding to target gear and is intermeshed performance objective gear it is changed again
Keep off that the time is long, the situation of power interruption time length, the utility model moved simultaneously by different synchronizers 50 respectively with currently
Second gear 404 is separated corresponding to gear, and second gear 404 corresponding with target gear is mutually close and engages, and effectively subtracts
Lack the transforming gear time of adjacent gear positions number, and then shortened the power interruption time of vehicle, lift the usage experience of user,
The satisfaction that user uses is improved, while improves the competitiveness of product in market.
