Abstract
The utility model relates to a structure for a double-clutch type automatic transmission to realize fast starting of a vehicle. The structure consists of a second-gear and reverse-gear synchronizer assembly, a second-gear gear, a reverse-gear gear, a reverse-gear idle wheel, a first-gear gear and a transmission. The structure is characterized in that the second-gear and reverse-gear synchronizer assembly and a first-gear and third-gear synchronizer assembly are distributed on a middle shaft; the reverse-gear idle wheel is distributed on an idle wheel shaft; the first-gear gear is connected with an odd-gear clutch; and the reverse-gear gear is connected with an even-gear clutch. The structure has the characteristics of short vehicle-starting time, fast and reliable gear shifting and the like.
Description
Technical field
The utility model patent relates to a kind of structure that double-clutch automatic transmission (DCT) can be realized the vehicle fast starting that is used for, and belongs to the automatic gearbox technical field of auto manufacturing.
Background technique
Along with the fast development of automobile pollution and the rapid increase of amateur driver's quantity, automatic gearbox is just presenting fast development trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT) and double-clutch automatic transmission (DCT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, also is present most widely used automatic gearbox.It does not cut off power gear shifting, has starting, smooth gear shifting, but to advantages such as resisting moment variation self adaptions.But shortcomings such as it also has complex structure simultaneously, and difficulty is made, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is that efficient is high, and cost is low, and mature production technology is widely used in China at present.Shortcoming is a gearshift difficulty, and power interruption during gearshift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that self shifter becomes possibility.Double-clutch automatic transmission (DCT) is the automatic mechanical transmission of a new generation; It has inherited high, the many advantages such as installing space is compact, in light weight, low price of manual transmission transmission efficiency; Fundamentally solved the cut-out power gear shifting problem that electric control mechanical type automatic speed variator exists; Greatly improved shifting comfort, guaranteed that vehicle has good power character and gear shifting characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer by strange, even number gear respectively with input shaft on two clutch C1, C2 being provided be connected, clutch C1, C2 replace transferring power and switch to realize gear.
During DCT work, with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of getting into according to the signal of related sensor to vehicle earlier; Because of this gear clutch separation transferring power not also,, mesh this gear in advance so instruction hydraulic control solenoid valve is controlled gearshift actuator very easily; When vehicle operating reaches shifting points; The clutch separation that only need will work simultaneously with another clutch, then makes automobile go with next gear.In shift process, the power of motor constantly is passed to wheel all the time, so the shift process of accomplishing like this is a power gear shifting.Vehicle implementation the power gear shifting process, will improve shifting comfort greatly, simultaneously guarantee that also vehicle has good and economic, aspects such as vehicle oil consumption and discharging are made moderate progress.
Summary of the invention
Characteristics such as the purpose of the utility model provides a kind of structure that double-clutch automatic transmission can be realized the vehicle fast starting that is used for, and has vehicle start time weak point, and gearshift is fast reliable.
The technological scheme of the utility model is achieved in that a kind of structure that double-clutch automatic transmission can be realized the vehicle fast starting that is used for, the You Er ﹑ synchronizer assembly that reverses gear, and second gear, reverse gear, the idle pulley that reverses gear, first gear and speed changer are formed; It is characterized in that: the synchronizer assembly that two, reverses gear, one, three retaining synchronizer assemblies are arranged on the jack shaft, and the idle pulley that reverses gear is arranged on the idler shaft; First gear links to each other with odd number retaining clutch, and reverse gear links to each other with even number retaining clutch.
The good effect of the utility model is that Ju has the Jie structure Jian Dan ﹑ characteristics with reliable operation easy to use.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Fig. 2 is the utility model De Yi ﹑ power transmission line figure that reverses gear.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: a kind of double-clutch automatic transmission that is used for can be realized the structure You Er ﹑ of the vehicle fast starting synchronizer assembly 2 that reverses gear, second gear 1, reverse gear 3; The idle pulley 4 that reverses gear, first gear 5 and speed changer are formed; It is characterized in that: the synchronizer assembly 2, that two, reverses gear, three retaining synchronizer assemblies are arranged on the jack shaft, and the idle pulley 4 that reverses gear is arranged on the idler shaft; Because first gear 5 links to each other with odd number retaining clutch, reverse gear 3 links to each other with even number retaining clutch, and the gearshift characteristics of DCT can realize hanging up simultaneously first gear 5 and reverse gear 3.Like this, this project organization can be realized reducing the gearshift time, hangs the disconnected gear of anticipation in advance, has reduced start-up time, makes gearshift quick more reliable, improves the power character of car load.Because of second gear 1 and reverse gear 3 shared same synchronizer assemblies.Because having, DCT can hang structural feature in advance into next gear when gearshift; At this moment since first gear 5 and reverse gear 3 on two different synchronizer assemblies; We can the control strategy of DCT be designed to hang up simultaneously one the retaining and reverse gear; Like this, can realize that a retaining and the synchronizer that reverses gear engage simultaneously.Owing to can only hang during vehicle start into a retaining or reverse gear, can realize reducing the gearshift time, hang the disconnected gear of anticipation in advance, reduced start-up time, make gearshift quick more reliable, improve the power character of car load.
