Abstract
The utility model relates to a novel front bearing cap structure of a dual-clutch automatic gearbox. The novel front bearing cap structure consists of a front bearing cap and a lining and is characterized in that the internal wall of the front bearing cap is in interference fit with the lining; the front bearing cap is provided with two clutch pressure oil holes and a clutch lubricating oil hole. The novel front bearing cap structure of the dual-clutch automatic gearbox has the features of simple structure, low cost and reliability in working.
Description
Technical field
The utility model relates to a kind of novel double-clutch automatic transmission front bearing retainer structure, 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 shfit, has starting, gear shift is smooth-going, but resisting moment is changed advantage such as self adaption.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 gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit 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 shfit problem that electric control mechanical type automatic speed variator exists; Greatly improved the gear shift travelling comfort, guaranteed that vehicle has good power character and shift 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 to realize gear switch.
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 gear-shifting actuating mechanism very easily; When vehicle operating reaches shift point; The clutch separation that only need will work simultaneously with another clutch, then makes automobile go with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure of accomplishing like this is a power shfit.Vehicle implementation timing, will improve the gear shift travelling 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
The purpose of the utility model provides a kind of novel double-clutch automatic transmission front bearing retainer structure, and Ju has the Jie structure Jian Dan ﹑ characteristics with reliable operation with low cost.
The technological scheme of the utility model is achieved in that a kind of novel double-clutch automatic transmission front bearing retainer structure; Form by front bearing retainer, lining; It is characterized in that: front bearing retainer inwall and lining interference fit, front bearing retainer have two clutch pressure oilholes and a clutch lubrication oilhole.
The utility model good effect is that Ju has the Jie structure Jian Dan ﹑ characteristics with reliable operation with low cost.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description: a kind of novel double-clutch automatic transmission front bearing retainer structure, form and it is characterized in that by front bearing retainer 1, lining 2: front bearing retainer 1 inwall and lining 2 interference fit; Front bearing retainer 1 has two clutch pressure oilholes 3 and a clutch lubrication oilhole 4, guarantees that clutch obtains enough pilot pressure oil and cooling oil mass.
