Description
Technical field
The utility model relates to transmission technology field, particularly relates to a kind of differential coupling automatic transmission.
Background technique
The double-clutch speed changer (DCT) of prior art grows up on the basis of manual transmission technology, manual transmission is divided into two-part design concept, a part transmits odd number shelves, another part transmits even number shelves, and its transmission of power is by two clutch couplings, two input shafts, the driven gear of adjacent each shelves is staggered to be engaged with two input shaft gears.When engaging with odd number shelves input shaft gear at the driven gear of a certain odd gear, the clutch connecting this axle is in jointing state, the driven gear of adjacent next gear now engages with even number shelves input shaft gear, but the clutch connecting this axle is in separated state, when needs conversion gear, while controlling the clutch separation of odd gear, the clutch controlling even gear engages, thus shorten shift time, effectively improve property of automatic shft.But because its state is that the gear gear that access one is new again more first cut off in a job works on, still there is of short duration incoherent problem that Power output engages.
Existing automatic transmission primarily of: torque converter, planetary transmission, control mechanism form.Automatic transmission has processing ease, driving comfort, can reduce the advantage of driver's fatigue, has become a kind of developing direction of Modern Car configuration.The automobile that automatic transmission is housed can according to pavement behavior automatic speed-changing and torque-converting, and driver can watch road traffic attentively absorbedly and can not be done in a rush by gearshift.Automatic gearbox common are three kinds of patterns: be hydraulic automatic speed variator (AT), mechanical stepless automatic speed changer (CVT), electric-controlled mechanical automatic speed transmission (AMT) respectively.
Current car generally uses AT, and AT almost becomes the synonym of automatic transmission.AT mainly refers to the automatic transmission of planetary gear structure, the change of velocity ratio is realized by the load path of control lines star-wheel mechanism, the namely change of gear, there is fluid torque converter speed changer front end, realizes flexibly connecting and the stepless change in certain ratio coverage.Oil consumption height mainly contains two influence factors: one is transmission efficiency, just because of the existence of fluid torque converter, there is certain loss in efficiency.Automatic transmission in the market, also with regard to the popular DSG of AMT and DCT() transmission efficiency can be suitable with manual transmission; Two is economic work states of motor, and automatic transmission can both realize making engine operation in economic zone, and manual transmission must need skilled driver to realize.
CVT is due to the driving gear without general automatic catch gearbox, and also just without the shift process of automatic catch gearbox, the gear shift pause and transition in rhythm or melody sense brought thus also disappears thereupon, and therefore the Power output of CVT gearbox is linear, very smooth-going in reality is driven.Gear can be more in theory for the transmission system of CVT, and gear setting is more free, and the balance of the gear ratio in conventional drivetrain, speed ratio and performance, oil consumption, toxic emission, all more easily reaches.Also have the mechanical efficiency of CVT transmission, performance is better than common automatic catch gearbox greatly, be only second to manual gear gearbox, fuel economy is than well a lot.Its shortcoming is: first starting or accelerate, skidding easily appears in CVT steel band or belt, causes transmission of power to be affected, thus affects sense of acceleration and be subject to.Next is that CVT steel band or strapping requirement are higher.Although CVT structure is simple, if there is fault, not generally minor issue.This can have influence on use and the maintenance cost increase of car owner.
AMT transforms on mechanical transmission (manual ripple) original base, main change hand shift actuating element.Namely when overall drive mechanism is constant by install micro-processor controlled automatic handling system additional to realize gearshift automation.Therefore AMT is actually two actions being come complete operation clutch and gear selecting by a robot system.Because AMT can transform on the manual ripple basis of existing production, production inheritance is good, and the expense of input is also lower, easily for factory accepts.The core technology of AMT is that microcomputer controls, and electronic technology and quality will directly determine performance and the ride quality of AMT.Based on this, in order to improve the transmission efficiency of automatic transmission and make its uninterrupted outputting power, the utility model explores that research and development are a kind of can the smooth-going comfortable automatic control system realizing automatic shifting speed-variable, not only there is the high efficiency of gear-shift transmission, high pulling torque, and its power transmission does not interrupt in gearshift procedure.
