Speed changer.Common manual speed changer dynamic property troublesome in poeration and economy rely on the driving experience of driver, could realize it
Preferable economy and dynamic property.If realizing fluid drive, otherwise the existing dynamic interruption of two speed transmission gear shift,
Two control clutches is needed to realize gear shift, a clutch unclamps, the engagement of another clutch, due in order to when move
Power is not interrupted, and when a clutch is totally released not yet, another clutch will engage, and causes two clutches in this way
With certain work schedule overlapping compared with angle, the final service life for influencing clutch of friction is easily generated.Two grades of the present invention
Automatic transmission only needs to control a clutch, due to that can realize that power does not interrupt gear shift, is easily achieved and moves certainly
Shelves.
Or understanding current electric car automatic speed transmission gear shift power interruption by analyzing above, slipped when going up a slope
Slope phenomenon or clutch it is easy to wear be exactly that poor reliability or technology are not mature enough, therefore two-shift automatic variable speed on the market
It is that device promotes and applies and few.
Invention content
It is limited the purpose of the invention is to overcome and solve existing electric automobile motor efficient operation section, existing two
Or gear automatic speed variator has gear shift power interruption, occur slipping by slope phenomenon or clutch reliability easy to wear when going up a slope
The shortcomings that poor and problem provide a kind of two-shift automatic variable speed device for braking gear ring, to realize that electronic function is operated in efficient operation
Region.
The technical solution adopted by the present invention is to achieve the above object of the invention：Including planet carrier connecting shaft 1, planet carrier 2, row
