Description
Technical field
The present invention relates to transmission technology field, and in particular to the double clutch speed change used in a kind of many gear tractors
Device.
Background technology
Current transmission technology quickly grows, and automatic transmission technology is very ripe and is widely applied, but
It is that each automatic transmission all has certain merits and demerits.Automatic transmission mainly include hydraulic automatic speed variator,
Electric control mechanical type automatic speed variator, buncher, double-clutch automatic gearbox, they have been assemblied in different vehicles.
It is still many using the armstrong's patents such as balladeur train, engaging sleeve and synchronizer gearshift mode on current tractor, needed when tractor is shifted gears
Clutch is first separated, speed changer is then plucked into neutral, then block selecting, gearshift, finally engage clutch.So, clutch separation is worked as
Afterwards, before clutch is re-engaged again, the power of engine can not be passed to wheel and go to drive tractor to run, institute
To generate the interruption of power transmission in shift process, gearshift is slow, when being worked due to tractor running resistance than larger, and
Tractor mass is very big, if so there is power interruption in shift process, influence operating efficiency influences the dynamic property of tractor
And fuel economy.
Traditional gearbox is constantly increasing casing internal gear quantity to pursue more gears, and gear is excessively multiple
Miscellaneous, transmission case also becomes excessively huge.Cost is not only increased, and the gear for providing can not fully meet tractor each
